00:14 <rust_collector> works on both skodas and b&s mowers
00:49 <rust_collector> and none of those will run very very long on an empty tank....
12:20 <rust_collector> why are my gas cans always empty...
16:51 <Ysjoelfir> xD you should get a big fuel tnak in your yard
17:43 <rust_collector> I would think having 60 liters worth of cans should do... but they always end up empty
18:16 <rust_collector> well, 80, but the jerry can is a bit... like a jerrycan, and I do not like using it
18:34 <Ysjoelfir> I have 30 liters on hand, 5 of them two stroke mix
18:53 <rust_collector> Hmm, I do need some 2 stroke oil
19:27 <rust_collector> I should get the atv thing going some time one of these years
20:31 <rust_collector> its issue, was the ignition switch. But now the issue is that it has been sitting for years, so I guess I have to replace all the chinese rubber lines
21:27 <rust_collector> and it probably had clogged up the oil tank and pump and all that crap
22:03 <rust_collector> mmh, Maybe just disconnect that for now, and mix in the fuel
22:59 <rust_collector> have you tried running a moped on chainsaw fuel?

25:19 <rust_collector> heh, we did try running nitrous on a 2 stroke once, that was... exciting
33:52 <Ysjoelfir> no, does it work?
34:15 <rust_collector> I am sure it will run... I don't know how it will run...
34:26 <Ysjoelfir> regarding ATVs - I saw a 6x6 ATV in norge back then. that was a cool beast, dragging a big trailer around the woods.
34:32 <rust_collector> tends to be expensive.
34:46 <Ysjoelfir> I assumed that
34:58 <rust_collector> oh yes, I think it was polaris that started with the 6 wheel atvs
35:25 <rust_collector> they even had a "dump bed"
35:41 <rust_collector> I am not sure how useful that was, but...
35:42 <Ysjoelfir> yes, that one had it
35:55 <Ysjoelfir> the girl riding it had her tools stuffed into that
36:31 <rust_collector> they will pull pretty much anything you could imagine. they are quite impressive
37:01 Quit: Lemon ([email protected]) EOF from client
37:42 <Ysjoelfir> I was very impressed. actually I was like "Kelly, I want that one! with the trailer! and with the girl!" - Dunno why she disagreed though
38:06 <rust_collector> no turbo... that must be it
38:21 <Ysjoelfir> that sounds like a legit reason, yes

04:00 <rust_collector> ok, I am going on a mower rescue mission. oh, and to get some fuel
04:05 <rust_collector> have fun
04:48 <Ysjoelfir> make a youtube video! or at least some pics
31:45 Join: Lemon ([email protected]) to #EEVblog
38:42 <rust_collector> uhm... too late
40:16 <rust_collector> I can sum it up as... take the plug out, take the air filter out, chat with the guy for 3-4 minutes, put the plug back in, put the filter cover back on, fire it up, test it, tell the guy to put a new filter in it, go home
49:53 <rust_collector> and, I get paid in baked potatoes, with everything, except mushrooms
52:19 <Ampera> good morning
53:16 <Lemon> back
53:23 * Ampera me squeezes Lemon 
53:32 <Lemon> sprouich
53:47 <Ampera> now you're gonna end up like that cat
55:02 <Lemon> I ended up bringing him to the vet
55:21 <Lemon> it was her uterus, it went out and reversed itself
55:37 <Lemon> it happens sometimes, he will remove it and maybe she'll live
55:56 <Ampera> that's good
56:00 <Ampera> at least you were able to get it care
59:42 <Lemon> yeah, it will be another big expense for my mother, but we cant let something die without doing anything
00:19 <Lemon> man im so tired of frenchies that dont want to take paypal
00:22 <Lemon> 'only cheques'
00:31 <Lemon> ffs its the number one way to get fucked up
00:36 <Lemon> how can one be so dumb
01:42 <Lemon> he was selling some banana grabbers and crocodile clips, for 10 euros
02:05 <Lemon> its so sad to find nice things that you cant buy because the seller is living under a rock
04:31 <Lemon> and the guy with the fluke ac clamp, who accepted the paiement via the website, isnt responding anymore now that I paid
04:41 <Lemon> so I'll have to wait a few days to get my money back
04:51 <Lemon> why the fuck bother to put stuff online if you dont want to sell it ?

25:04 <Lemon> I have a new project that came to my mind yesterday
25:19 <Lemon> a multi-channel voltmeter, to measure my power supplies and log the data
25:39 <Lemon> accuracy down to at least 1mv would be nice
25:43 <Lemon> it should be achievable
26:05 <Lemon> https://www.ebay.fr/itm/ADS1256-8-Channel-24Bit-Data-ADC-Module-Multi-Channel-Acquisition-AU/323037290767?_trkparms=ispr%3D1&hash=item4b3685e10f:g:g6kAAOSwISRabkkW
26:36 <Lemon> with that kind of multi-channel adc, can it work ? I also need some op-amps for the input voltage I think, and maybe an external Vref
26:47 <Lemon> I'll use an arduino or whatever as the uC
28:21 <Lemon> input voltage will be as high as 50v, maybe 30 can be enough
33:50 <Lemon> hmmm I could build a voltage divider
43:56 <Lemon> if my input is 50v, with a 24 bits adc
44:06 <Lemon> I get 2uV steps, right ?
44:21 <Lemon> 50/2 exponent 24
47:18 <MrMobodies> Hello
47:26 <MrMobodies> need an opinion
48:44 <MrMobodies> that's an interesting controller above
48:45 <MrMobodies> TI ADS1256IDB ADC chips
48:48 <Ampera> MrMobodies, you're not that ugly
48:49 <Ampera> oh
48:52 <MrMobodies> aah
49:05 <MrMobodies> my dad order £800 worth of goods
49:13 <MrMobodies> it ended up at our old address
49:47 <MrMobodies> neighbour checked with the occupants, they said they did receive but refused it as it is not their name
50:05 <MrMobodies> they didn't accept the delivery
50:15 <MrMobodies> driver is saying they delivered it and accepted it
50:27 <Ampera> Take your powder, take your gun, and powder like it's 1776
50:33 <Ampera> *powder -> party
50:40 <MrMobodies> signature: C.(firstname)
50:43 <MrMobodies> I see
50:49 <MrMobodies> wild west
50:55 <Ampera> no, wild east
51:13 <MrMobodies> I'll start with the shed
51:25 <MrMobodies> it is likely there, if they have it in their possesion
51:51 <Ampera> Remember, if you get caught breaking and entering, I'm not responsible, though I may be proud
52:52 <Lemon> rip and tear, until its done
53:09 <Lemon> ampera ! what do you think of my great multi-channel voltmeter idea ?
53:24 <Lemon> 50v inputs max, as many channels as possible, mv accuracy/resolution
53:26 <Ampera> Lemon, didn't read it
53:32 <MrMobodies> can they also be used for audio?
53:37 <Ampera> looks interesting
53:38 <Lemon> I can use whatever external Vref and calibrate it with my dmms
53:51 <Lemon> https://www.ebay.fr/itm/ADS1256-8-Channel-24Bit-Data-ADC-Module-Multi-Channel-Acquisition-AU/323037290767?_trkparms=ispr%3D1&hash=item4b3685e10f:g:g6kAAOSwISRabkkW
53:56 <Lemon> do you think this can be used ?
54:19 <Lemon> ho and I found a 4 meters amphenol gpib cable for 30 euros delivered
54:28 <Lemon> that way I dont have to move my damned tek tds 540
55:32 <MrMobodies> for a volt meter, sounds interesting to see what happens
55:34 <Lemon> but I mean, getting mv accuracy/resolution shouldnt be too hard no ?
55:44 <Lemon> I want to log power supplies for example
55:47 <Lemon> without using my dmms
57:04 <MrMobodies> I wouldn't know about accracy but another listing on a 16 bit board talks about the resolution https://www.ebay.fr/itm/AD7606-DATA-Acquisition-Module-16Bits-ADC-200Ksps-8CH-Synchronization/263694139804
57:06 <Lemon> for the input, I guess I can use a voltage divider ?
57:24 <Lemon> well the resolution is simple to figure out
57:32 <Lemon> input/2 exponent 24
57:40 <Lemon> 50v max, and I get 2uV steps
57:44 <Lemon> which is more than enough
57:55 <Lemon> so I can get more samples by second I guess, if I use less steps
58:20 <MrMobodies> I am not an electrician... sorry I can't give decent answers.
58:29 <Lemon> neither am I :>
58:43 * Ampera starts an electrical fire, throws T3sl4 on it
58:48 <MrMobodies> but you seem interested and when you post pictures of it working, I learn stuff
59:12 <Ampera> oh man I am existentially tired
59:12 <Lemon> I want to work in that area so im trying to learn as much stuff as I can !
00:21 <Lemon> im pretty happy about how the thermometer turned up
00:23 <MrMobodies> maybe later the folks may come on and
00:31 <Lemon> the software could still benefit of some tweaks, but it works
00:55 <MrMobodies> that's nice, I can't barely build anything to save my life
01:20 <MrMobodies> I did replace the door handles that were badly installed by the previous owners in my worlkshop
01:50 <MrMobodies> so they, you know shut without a problem. the wooden needed to come out more with a chizzel
02:08 <Lemon> thats something !
02:13 <MrMobodies> ops chisel
02:37 <MrMobodies> I put rubber so it doesn't go bang and moves about in the wind
02:45 <MrMobodies> in the corners
03:13 <MrMobodies> I dug too deep in one of the doors but the gluegun came in handy
03:28 <MrMobodies> made the latch holder level

04:01 <Lemon> the glue gun is one of the greatest inventions
04:12 <Ampera> The gun is an even greater invention
04:35 Join: Halcyon ([email protected]) to #EEVblog
04:51 <Lemon> yeah but it aint that great to glue stuff sadly
05:01 <Ampera> no but you can shoot poor people
05:03 <Lemon> you know what I find funny ?
05:11 <Ampera> shooting minorities?
05:14 <Lemon> in france, you have to be 18 y/o to buy an airsoft gun
05:29 <Ampera> you have to be 16 to buy a BB/pellet gun
05:31 <Lemon> but you can go in any tool shop, get yourself a gas nail gun
05:34 <Ampera> not sure about plastic projectiles
05:41 <Lemon> and fucking murder people
05:52 <Ampera> you can also go into any kitchen, get a knife, and fucking murder people
05:53 <Lemon> and trust me that shit is really scary
06:05 <Lemon> yeah but the nail gun man
06:08 <Lemon> ever used one ?
06:09 <Ampera> so?
06:13 <Lemon> its really impressive
06:21 <Ampera> iirc they're just 22 blanks
06:24 <Lemon> you can shoot people like 50m afar easily
06:43 <Lemon> its using gas to compress a chamber
06:59 <Ampera> Thermite explosive, sparkler to light, and a steel pipe can easily be a gun
07:18 <Lemon> yeah sure, but I found this funny because of the legislation
07:25 <Lemon> an airsoft gun ? man thats too dangerous
07:31 <Lemon> a nail gun ? here you go hf
07:34 <Ampera> In the US you can, in private trade, just buy a gun
07:37 <Ampera> and own it
07:39 <Ampera> that's it
07:47 <Lemon> not everywhere but yeah
07:53 <Ampera> most places
07:53 <Lemon> in france you can with some limitations
08:07 <Ampera> go to someone's house, give them money, get a gun, and bring it home
08:13 <Ampera> it's now your gun to do with as you please
08:20 <Lemon> and what people dont understand is that most mass murder happen in states where guns werent allowed :>
08:45 <Lemon> the dude isnt a fool, he knows he'd get gunned down in seconds
09:01 <Lemon> well it will eventually happen anyway
09:07 <Lemon> but he still get a chance to kill peeps
10:05 <hsn_> reminds me of the joker few years ago
10:20 <Lemon> its funny because I was watching some postal 2 videos earlier, I kinda want to play it again
10:20 <hsn_> he entered batman movie and started shooting people
11:55 <MrMobodies> I brought a lighter 20 years ago in the shape of a gun
12:03 <MrMobodies> I use to carry it around and play with it
12:05 <Lemon> freaking madman !
12:21 <MrMobodies> someone said "do that now and you'll be met with armed response"
12:52 <MrMobodies> someone may think it'll be a real gun and call the police
13:17 <Lemon> thats not false, dumb peeps are everywhere
13:18 <MrMobodies> I used it to set light to things to burn
13:46 <MrMobodies> I got a collection of lighters
14:02 <MrMobodies> I got them down bootsales and i use to repair them
14:20 <Lemon> thats neat ! I kinda want to find a dupont one day
14:25 <Lemon> the older ones
16:17 <Lemon> ok so back at that multi channel voltmeter
16:21 <Lemon> it looks too easy to be true
16:33 <Lemon> I just need a voltage divider to read 50v max ?
16:42 <Lemon> a simple 10:1 ? as the adc can read 5v max
16:44 <rust_collector> MrMobodies, just call the shipping company. it is ok if the new owner of the property signed and took the goods, but they can not let them have the stuff unless your dad said it could be left with whoever wanted to sign for it
19:17 <MrMobodies> nope..., they signed a name similar to my dads
19:34 <MrMobodies> not the one on the order
19:58 <MrMobodies> I would have expected the occupant to sign so we no they have it
20:04 <MrMobodies> or the driver to refuse delivery
20:23 <MrMobodies> not try and use my dads name in a way lets say
20:49 <MrMobodies> Dave jones... Signed by Dave.D
21:00 <MrMobodies> and a scribble for the writing
21:27 <rust_collector> sure. but it is still their problem to fix. it does not matter what they sign it with. they have to make sure it is the guy they are delivering to
21:51 <MrMobodies> this is where I think the delivery driver is responsible
22:04 <Lemon> ultimately its the sender
22:10 <Lemon> expeditor
22:13 <MrMobodies> I could just sign "Santa Claus" and draw a little elf on the signature
22:15 <Lemon> well, in france it is at least
22:29 <MrMobodies> lighters:
22:30 <MrMobodies> https://i.imgur.com/b7He8GM.jpg
22:46 <Lemon> wow thats a neat collection
22:56 <Lemon> I like the table ones
23:16 <MrMobodies> I have some wiered ones
23:19 <rust_collector> well, yes, if you talk to the guy who sent it, he can complain for you. he is after all the customer
25:32 <MrMobodies> https://imgur.com/a/st4M3Tr
25:47 <MrMobodies> that would be the seller
25:58 <rust_collector> yes
26:09 <MrMobodies> the seller has also complained that they should have taken a picture as standard with many other couriers
26:32 <MrMobodies> Fedex are saying, they delivered it, got a signature and it is not their problem
27:55 <MrMobodies> I said, look, signature is wrong and in poor attempt in pretence, therefore it is fraud
28:46 <MrMobodies> either the driver or the occupant is lying, but I think the driver is responsible for not checking for example: "D.Dave" when it should have been "Dave Jones"
29:04 <MrMobodies> and the scribbling
29:12 <rust_collector> meh, the driver is the company
29:54 <MrMobodies> I see, the driver does all the work for the company
30:00 <MrMobodies> without drivers they cease to be
30:46 <MrMobodies> I opened a case on Paypal, it was from a UK shop but not Ebay
31:22 <MrMobodies> I'll spend all day tomorrow trying to contact them to get their advice, if they did reverse the charges can the seller try to sue.
31:28 <rust_collector> nono. you can not complain to the driver.... if you have a complaint, you can say you have something to complain about, and he will give you contact information to the office, who is the place you make a complaint. the driver does not do complaints. he does driver-ing
31:33 <Lemon> http://www.ti.com/lit/ds/sbas288k/sbas288k.pdf?&ts=1589912538525 I cant find if it got an internal Vref
32:02 <MrMobodies> I did contact the seller, the seller said to complain to Fedex and Fedex are saying complain to the seller
32:20 <MrMobodies> sending me in circles
32:30 <rust_collector> right, they are correct there, you have to complain to the seller
32:38 <Lemon> the seller is responsible
32:43 <Lemon> so you tell him to move his ass
32:46 <MrMobodies> so when I get through to Paypal, I'll explain what the seller is doing
32:49 <Lemon> before you fill up a fraud complain
32:50 <rust_collector> the seller is fedexs customer
32:53 <Lemon> ho paypal ?
32:55 <Lemon> even better !
32:59 <MrMobodies> yes

33:36 <rust_collector> hmm, does the seller live on your old address?
33:40 <MrMobodies> not fraud at the moment, just didn't receive item
34:03 <MrMobodies> nonono they got the details from my dad's Paypal account and he has been having some issues changong the address
34:30 <MrMobodies> I am not sure how he sent it to the old address but I think he didn't change "delivery address" but changed the billing one
34:47 <MrMobodies> but there is no reason why it shouldn't be at the old address.
34:59 <MrMobodies> to pick it up
35:12 <MrMobodies> but the occupants say they refused it
35:59 <MrMobodies> I phoned up the police advice line and they said, just go on Paypal and open a dispute
36:08 <Lemon> yeah just do that
36:19 <MrMobodies> So I'll see what happens
36:38 <rust_collector> paypal is usually pretty good at those things
37:05 <MrMobodies> if they reverse the charges, I wonder would the seller than try to sue
37:38 <MrMobodies> that's why I am going to try tomorrow to phone Paypal, at the moment they are shut for the night.
38:33 <MrMobodies> I am going out for walk for a little while
38:41 <MrMobodies> very hot but nice and breezy with the trees
38:47 <MrMobodies> lots of trees here
39:12 <rust_collector> i have been outside for a few hours today, in just a t shirt. it is different
39:31 <rust_collector> I guess I should have put a sock on too, but...
43:15 <Lemon> Hey Ysjoelfir ! I need your knowledge : I want to build a 8 channel voltmeter, with mv accuracy/resolution minimum or better if possible, and 50V input max to log power supplies
43:24 <Lemon> I found this : https://www.ebay.fr/itm/ADS1256-Module-24-bit-8-channel-ADC-Data-Acquisition-board-high-Precision-L40/232856284826?hash=item363750ee9a:g:oBUAAOSwrvNbUSIy
43:41 <Lemon> can I use that, along with a Vref, an arduino or whatever uC, and a voltage divider at the input ?
43:48 <Lemon> and calibrate everything with my dmm ?
44:17 <rust_collector> whyyyy would you log a bunch of power supplies?
44:50 <rust_collector> wait, I don't want to know. Go on
45:01 <Lemon> well its always nice to have the true voltage input when powering something, and I dont want to use a dmm for that when it can be used for something that require accuracy, and it can be probably used for something else !
45:06 <Lemon> its also a neat project I think
47:05 <rust_collector> dont use shitty long cables? I dunno, but go on. you want a project, it is good
47:21 <Lemon> shitty long cables ?
47:23 <Lemon> I dont understand
47:38 Quit: qeed ([email protected]) Client exited
48:06 <rust_collector> that is ok.
48:25 <rust_collector> it won't be a problem, if you use that thing anyway
48:43 <Lemon> yeah and a 8 channel voltmeter is a nice thing to have I guess
48:49 <Lemon> when you need to measure a ton of things at once
49:27 <rust_collector> yes, because you just can not have enough meters
49:36 <Lemon> exactly
49:40 <Lemon> and I like building tools
49:46 <rust_collector> is it done soon?
51:33 <Lemon> first I want to know if my expectations are reachable, then I order stuff
51:36 <Lemon> then I build :>
51:43 <rust_collector> NOOOO!!!!
51:52 <rust_collector> just build it first
55:16 <rust_collector> ADS1256 module is suitable for measuring analog voltage within 3V.... so, you would... uhm, divide the voltage before measuring it?
55:27 <Lemon> yes
55:32 <Lemon> thats what I thought
55:51 <Lemon> I want to measure stuff up to 50v, so like, a 12:1 divider or whatever
57:07 <rust_collector> shouldn't you be building a resistor box one of these days?
58:08 <Lemon> its on the list yeah
58:27 <Lemon> a variable bnc attenuator would be nice too
58:50 <rust_collector> that sounds dangerous
00:06 <Lemon> why that ?
00:16 <Lemon> I found many for sale but I figured out it wouldnt be too hard to build after all
00:21 <rust_collector> because it is adjustable
00:24 <Lemon> some power resistors and bam
00:31 <rust_collector> mmhmm
02:58 <Lemon> but first the multi channel voltmeter
03:54 <Lemon> it seems I need a 2.5v reference
04:16 <rust_collector> so, you are not using those boards?
05:10 <Lemon> well yes, that 8 channel 24bit adc sounds nice
05:32 <rust_collector> on board ADR03...
05:49 <rust_collector> i guess those are reference voltage things?
06:12 <Lemon> well I read the documentation and only found external inputs for the vref
06:15 <Lemon> so yeah idk
06:19 <Lemon> I dont think theres internal vrefs
07:13 <rust_collector> documentation for that module, or the chip? Well, you will figure it out
07:23 <Lemon> the module
07:27 <Lemon> the chip sorry
07:31 <Lemon> hmmm you are right
07:36 <Lemon> usually you find everything
07:38 <Lemon> please help
07:42 <Lemon> halp me rusty
08:01 <rust_collector> I don't fucking know a damn thing.... I just read what it said on ebay, lol
08:14 <Lemon> you are better at that game than me
08:26 <rust_collector> letters and numbers... yes
08:45 <rust_collector> translating that to something usable... not so much
09:20 <Lemon> hmmm you are right
09:27 <Lemon> it seems those adr03 are voltage ref
09:52 <Lemon> probably good enough for mv accuracy
10:05 <Lemon> I dont mind bigger resolution
10:13 Join: qeed ([email protected]) to #EEVblog
10:36 <rust_collector> I would be more worried about stability of things, and maybe especially the divider thingies?
11:15 <rust_collector> if you just want something sane, it will probably be just fine
11:42 <Lemon> staability of 1k hours is 50ppm
11:45 <Lemon> which is good
11:48 <rust_collector> you will have to box up the cats, and store them next to the bench, while you are measuring things
11:51 <Lemon> more than enough
11:57 <Lemon> hah yeah
12:05 <Lemon> have I told you what happenned today ?
12:11 <rust_collector> no
12:14 <Lemon> a cat that we never saw came here
12:19 <rust_collector> ooh
12:21 <Lemon> with her uterus hanging out...
12:31 <rust_collector> hmm. that is not ideal
12:41 <Lemon> we managed to pack her and I drove her to the vet
13:02 <Lemon> he told me that it was like that for maybe a day or two as it was starting to rot
13:11 <Lemon> he will remove it tonight and tell us tommorow
13:24 <rust_collector> well, that is something
13:28 <Lemon> it happens sometimes, he usually see that once per year
14:05 <rust_collector> i have only seen that in cows, and.. well, I did not look, but wifes friend had that
14:30 <Lemon> that was kinda hardcore honestyly
15:43 <rust_collector> well, I gues you saved that cat. and it will not make any more kats, so that is good
16:09 <rust_collector> what is carte bleue?
16:23 <rust_collector> my french is not awesome
16:25 <Lemon> a type of credit card
16:31 <rust_collector> ok
16:40 <Lemon> yeah I hope she'll be ok
16:48 <Lemon> hmmmm the module is much cheaper in china
16:56 <Lemon> but well Idk if I want to wait
17:03 <Lemon> but its 20 euros cheaper, which is significant
17:03 <rust_collector> heh, who would have thought....
17:22 <rust_collector> yes, order 2, and go do something else for a while
18:07 <Lemon> I also need a linear supply module
18:13 <rust_collector> uuh
18:33 <rust_collector> a what?
18:54 <Lemon> you know to power the thing
19:00 <Lemon> a noise free supply
19:13 <rust_collector> are you sure the thing cares?
19:24 <Lemon> yeah im kinda sure of it
19:35 <rust_collector> but ok. uhm, a 5v linear thing
19:39 <Lemon> in multimeters you can find some really high quality linear supplies
19:46 <Lemon> so im pretty sure its important
20:17 <rust_collector> look for a linear led driver? those might be good enough, and probably not expensive?
21:50 <rust_collector> or just use an antenna, and collect 5g energy, ploink it into a large capacitor, and...regulatify it to 5v?
22:13 <Lemon> hmmmrmf
22:48 <rust_collector> it is the new thing, you know... might as well keep up to date
23:45 <Lemon> true true
23:49 <Lemon> hmmm I need more info
23:54 <Lemon> maybe its not really needed as you said
24:01 <Lemon> in that case I can use a random 5v wart
24:15 <Lemon> but if it makes a difference, I need a linear one
24:26 <Lemon> ho wait
24:37 <Lemon> on my topward supply, theres a fixed 5v 3a output I never use
24:41 <Lemon> I can use that
25:04 <rust_collector> well, maybe you can use a 7 or 9v whatever supply, then use a whatever5v linear reglator...
25:44 <rust_collector> with some thingies in here and there, to knock the bumps off?
25:50 <Lemon> I'll go with the topward 5v output, that easier for now
25:57 <Lemon> but thats a possibility yeah
26:04 <Lemon> I also need a screen
26:10 <rust_collector> sure, but you need those on your list
26:18 <rust_collector> screen
26:18 <Lemon> I think I have some
26:22 <Lemon> 5v regulators
26:42 <rust_collector> or... if you use a real os, you can use....screen
26:55 <Lemon> well you know a display like the thermometer
27:01 <Lemon> so I can use it without it being connected
27:09 <Lemon> if I dont want to log stuff, just a regulat voltmeter
27:41 <rust_collector> you are already making a bunch of data weirdness, you might as well log
27:52 <Lemon> ho ofc I will log it
27:58 <Lemon> its the main reason I want to build that
28:06 <Lemon> but both options are nice
28:17 <Lemon> a screen for quick glance, and a software for logging like the thermometer
28:32 <rust_collector> I doubt you will use such a device off your bench, really...
28:46 <Lemon> not off, but sometimes I might not need logging
28:52 <Lemon> like I dont always log the temperature
29:03 <Lemon> but I like to read it to know whats going on
29:14 <rust_collector> well, then just don't log, you already have your confuser running...
29:24 <Lemon> :>
29:46 <rust_collector> did you order your old laptop yet?
29:56 <Lemon> nobody answered yet
30:19 <rust_collector> bastardssss, di dyou just ask frenchies or something?
30:47 <Lemon> frenchies and ebay sellers too
30:54 <Lemon> https://www.ebay.fr/itm/2-4-Zoll-Touchscreen-Display-fur-Arduino-Uno-LCD-Modul-TFT-Touch-Shield/283833809834?hash=item4215d03baa:g:angAAOSwC4ZehD9p looks fine
31:03 <Lemon> its tactile as a bonus I wont use, probably
31:12 <Lemon> but it seems to be hard to get a non tactile one anyway
31:36 <Lemon> also got a micro sd card reader, for some reasons
32:03 <rust_collector> 240X320... yes, that pic is certainly correct
32:17 <Lemon> perfect to display numbers
32:34 <rust_collector> yes, but not to display flower pics, lol
33:01 <Lemon> maybe but a tad more piexelated lol
33:12 <Lemon> but honestly they are quite good, I had one once
33:19 <Lemon> its impressive for the price
33:22 <rust_collector> ok, I dunno, I have one of those screens, but not in an arduino module form... it is from my old jyetech scope
34:10 <rust_collector> not touch, but... screen
34:22 <Lemon> https://www.ebay.fr/itm/3-5-inch-TFT-Touch-Screen-LCD-480x320-Display-UNO-R3-Board-For-Arduino-Mega-2560/163763739603?hash=item2621145bd3:g:7FUAAOSwZCBdo-mF
34:24 <Lemon> even better
34:33 <Lemon> and cheaper
34:44 Join: canadaguest ([email protected]) to #EEVblog
34:49 <Lemon> if I buy the adc module off china, I better get everything from there
34:52 <canadaguest> hi again for today
34:53 <Lemon> it wil be cheaper
34:56 <Lemon> hi again
35:00 <canadaguest> :)
35:11 <rust_collector> yes. make it big enough to split into 8 then
35:21 * canadaguest had a bit fun reading a lot of new library scans today
36:51 <rust_collector> I am not even sure if there is a library around here
37:31 <Lemon> ok then I need two good resistors for the divider
37:45 <rust_collector> yes, 16
37:50 <canadaguest> rust_collector well I was talking about that link someone provided earlier on today
37:52 <Lemon> shit 16
37:53 <Lemon> you are right
38:09 <rust_collector> eh?
38:38 <canadaguest> somewhat debating reading the mosfet ebooks to see if that might change my mind on the transformer itself or not but :)
39:15 <Lemon> so if I want to read 50v, when the module can take 3v max
39:41 <Lemon> I need to divide 50 by 17 at least
40:18 <rust_collector> what transformer?
40:34 <rust_collector> traaaans formersss DA DA TAAA!
40:45 <Lemon> so for example
40:55 <Lemon> a 10k and 638R
40:58 <Lemon> that would work
41:05 <Lemon> so I have to find easy to buy values
41:28 <rust_collector> Someone probably has that as a calculator online
41:35 <Lemon> yeah im using one
41:53 <MrMobodies> just got back
41:57 <rust_collector> that find easy to buy vaues?
42:07 <Lemon> no that calculate which values are needed
42:10 <Lemon> wb
42:17 <MrMobodies> 5 minutes under the air conditioner and don't feek sweaty
43:56 <rust_collector> so, Lemon someone probably has a calculator online to do that
44:14 <Lemon> I have no idea honestly
44:16 <canadaguest> rust_collector one for to drop wall voltage down to a more economical one for the rest of circuit? :) (re transformers..)
44:22 <Lemon> if you can find one I'd love it
44:29 <Lemon> im just looking at what is avalaible on ebay
44:36 <rust_collector> an economical voltage?
45:15 <MrMobodies> economical with voltage?
45:46 <MrMobodies> does that mean low voltage?
45:59 <rust_collector> I thought you people over there already had low voltage
46:51 <Lemon> I have to calculate the importance of the stability of those resistors
47:20 <rust_collector> just keep the toasty all the time, they will self-regulate
48:44 <canadaguest> rust_collector well I dunno what to call it so I just use whatever seem to make sense at the times .. and tbh some people think that 'low' still means 100v .. what do I know of what 'high' might mean to these same people
49:14 <rust_collector> well, I would say 117 kilovolts is pretty high
50:00 <Lemon> 25ppm resistors seems to be easy to find and not that expensive
50:02 <MrMobodies> I didn't know if it low DC voltage
50:02 <rust_collector> I mean, 100v is not high. but it is also plenty do do some damage
50:22 <MrMobodies> in the UK 220/240 AC
50:41 <rust_collector> the uk tends to be on the higher side, I believe
51:07 <rust_collector> I have not actually measured voltage here in many many years
51:48 <rust_collector> ok, let me stick my cheap chinese meter into mains... brb
52:17 <MrMobodies> Dave Jones and the UNIT
52:40 <MrMobodies> Send that in to the UL and they'll laugh at you.
53:10 <rust_collector> 232 over here
53:44 <Lemon> hmmmmm in fact
53:51 <Lemon> if the resistors are of the same brand/spool
53:57 <Lemon> they might drift in the same way together
54:03 <rust_collector> I still do not understand why people are worried about mains stuff anyway.
54:05 <Lemon> which is good
54:13 <rust_collector> Lemon, well, maybe...
54:32 <rust_collector> they may also be just really random... who knows?
54:39 <MrMobodies> wall plu meter 239 - 242
54:43 <Lemon> I'll have to characterize them somehow
54:51 <rust_collector> yep
54:58 <Lemon> well afterall I want mv accuracy minimum
55:01 <rust_collector> there goes that week. have fun
55:04 <Lemon> that might be doable if I find good enough resistors
55:45 <rust_collector> sure, maybe you can "double the up" and average them out? sort of, if you get what I mean
56:01 <Lemon> yeah
56:07 <rust_collector> 5 times the value, and 5 in paralell
56:11 <Lemon> or measure temperature, and calculate it
56:38 <rust_collector> or, maybe temp does not matter all that much, because the other side of the divider is equally hot?
56:38 <Lemon> but maybe it will be negligible for what I want to achieve
56:57 <Lemon> yes thats what I thought, also they might drift the same way
57:21 <rust_collector> I do think you want to measure a voltage, not the power, so... you do not need tons of current?
57:35 <canadaguest> rust_collector anyway tbh I haven't decided on a single number yet (still have to recheck what the loads like themselves) but it'll be anywhere between 15v to 26v straight from transformer ... and a to-yet-come low-emi rectifier circuit for the few dc-only loads elsewhere down the bus
57:35 <Lemon> ho no but im concerned about ambient
57:47 <Lemon> it wont be much but if I dont get low tempco resistors, it will play a role
57:53 <Lemon> and I dont want to spend a ton, remember
58:02 <Lemon> right now we are at 23 euros for the module + display which is fine
58:13 <rust_collector> so, make them high-ish values, so you get less heating, just enough to measure properly?
58:26 <rust_collector> Ok, I will stop, I might not make sense
59:04 <rust_collector> canadaguest, you are making a power supply for something on a bus?
59:35 <Lemon> well im playing with values
00:03 <Lemon> if I change one resistor by adding 100ppm
00:12 <Lemon> the output is moving in microvolts only
00:12 <rust_collector> I just mean, if you use 17 ohm on top, and 1 ohm on bottom, you will have tons of current, like?
00:18 <Lemon> ha yes
00:23 <Lemon> I plan to use values in the thousands
00:34 <Lemon> like 157k/10k
00:42 <canadaguest> rust_collector yes :)
01:08 <rust_collector> well, that is cool. I prefer trains myself...
01:53 <canadaguest> rust_collector oh I think I see where you could misread that .. by 'bus' I meant a primary circuit bus that the various small circuits would tap off from :)
02:19 <canadaguest> not bus as in road vehicles :P
02:45 <canadaguest> rust_collector and to be more funny this is actually for model trains :P
02:55 <rust_collector> cool! offroad buses are meat
02:59 <rust_collector> or neat
03:06 <rust_collector> oh nice
03:25 <rust_collector> have you tried dcc++?
03:46 <rust_collector> and, why you need the ac voltage?
03:56 <rust_collector> märklin stuff?
04:34 <canadaguest> you guessed right on the latter :)
04:40 <rust_collector> cool
04:55 <rust_collector> I think I still have a few of those
05:01 <canadaguest> and even the dcc station expects 15-24vac input, doesn't like dc
05:20 <rust_collector> ok
06:01 <rust_collector> I do look at model train stuff now and then, and it is like a different world now.
08:26 <rust_collector> I remember being pretty happy bout putting a pair of diodes on one side of the "direction change" relay in the engines, and a bridge rectifier and a reversing switch in the transformer box, so I could run each engine, using the speed thing, and the switch for direction, then the original direction change function switched to the other engine
09:10 <rust_collector> it was plenty for my tiny layout. I could not fit much more than 2 trains anyway
09:20 <Lemon> ok its time to sleep
09:30 <Lemon> I'll look for resistors tommorow
09:31 <canadaguest> bye lemon and don't lose resistance ;) hehehe
09:38 <Lemon> and ask around if the idea is feasible
09:42 <rust_collector> no no, it is time to get drunk, and go to ebay
09:45 <Lemon> bye peeps :>
09:55 <rust_collector> have enjoys frenchie
10:49 <rust_collector> I started with märklin, but I went for the dc stuff, pretty much because it was dirt cheap
11:31 <rust_collector> I think I have 3-4 engines. just small uninteresting ones.
12:50 <rust_collector> hmm, I think 2 are the "dhg500" industrial diesel things, and a "8000" tiny steam thing, with only the last axle driven
14:01 <rust_collector> Now, the kids are moving out... who knows what will happen
14:32 <rust_collector> how much power do you need out of this thing?
15:38 <canadaguest> varies from like 100ma to maybe at worst 3a per bus
16:28 Quit: Lemon ([email protected]) Connection closed
16:44 <rust_collector> how many buses?
17:10 <rust_collector> no one cares how little you draw from it, as long as it can handle the max, I guess
25:19 <canadaguest> sorry rust_collector .. seem like I can't browse digikey tonight they need to stop refusing to use a consistent website -_- but anyhow as for buses theres probably two maybe three, and yeah you're right re currents :)
25:56 <rust_collector> so, up to 9 amps... that is a bit
26:32 <rust_collector> maybe plus the train part
26:51 <canadaguest> actually one of the bus is already for the train motors :)
27:06 <rust_collector> is there any chance of all buses drawing all of the current at the same time?
27:13 <rust_collector> oh, ok
27:58 <rust_collector> still, that is a fairly chunky transformer. hmm, 20-ish volts...
28:52 <rust_collector> how about a 90's tuner-reciever-amplifier thing? they have some pretty hefty transformers, with a million windings
29:43 <rust_collector> also comes with some chunky caps and diodes, or rectifier brick things
29:49 <canadaguest> well I'm going by the assumption of about 300-700ma per motor and adding a bit allowance for constant-parasite (to put it mildly) interior lamps in locomotives/wagons
30:07 <canadaguest> so 3a just for the track alone doesn't seem too unreasonable with 2-3 trains active
30:37 <rust_collector> nope, I think most draw around 1a, if you stall them
30:43 <canadaguest> and the other bus..well I mean remote turnouts or house buildings etc
31:15 <rust_collector> and the turnouts are electromagets, or motors?
31:31 <canadaguest> plan on servo
31:58 * canadaguest wants to whack digikey with an iron pan perhaps
32:28 <rust_collector> no no, take care of iron pans
34:18 <canadaguest> what else should I hit digikey with? ;) hehe
34:48 <rust_collector> eeh, bricks... random explosives... something they make every day
35:14 <rust_collector> not good old iron pans
37:30 <canadaguest> ok :)
37:55 <rust_collector> when I quit tinkering with trains the tortoise switch motors was the thing. But damn, they were as big as a house in some cases
39:10 <rust_collector> I remember grinding and drilling a hole in a simple toggle switch, and used a piano wire over to the turnout, for the less used tracks. I kind of liked that
39:11 <canadaguest> yeah retail ones seem to have a weird case of obese-ness
39:38 <canadaguest> a homemade servo one takes up like 1/5th the footprint of what a tortoise wanted -_-
40:05 <rust_collector> ok, do you have a pic of a homemade servo?
41:25 <rust_collector> Part of me want to do a small narrow gauge layout. but otoh, narrow gauge things are not cheap either. But I guess there are less of everything in narrow-things in general...
42:01 <rust_collector> I did try a little bit of N, but.. yes, it works, but theyare damn small
42:32 <canadaguest> actually it depends, if you just want ng in general it can be quite cheap both retail and diy
42:58 <canadaguest> but if you for example specifically want hartz german ng .. or swiss ng then yeah these sort of fields can be expensive
43:12 <rust_collector> I do have some bemo things
43:17 <rust_collector> 12mm, iIrc
43:27 <canadaguest> heh if you think n is small you haven't tried z .. or even the more-recent 't gauge' (a japan creation)
43:38 <rust_collector> they were not cheap. they do run very very well tho
43:49 <canadaguest> t gauge is small enough that a locomotive can rest on the palm of your finger 0_0
44:05 <rust_collector> No, I have never had any interest in z, and much less anything smaller
44:36 <rust_collector> I can deal with n. but I like seeing the damn things when they run around
44:47 <canadaguest> well rust_collector just for the footnote z scale was a result of marklin trying to see how small a commerically-producable scale could be (long before super-precise modern computers existed)
45:07 <rust_collector> right
45:11 <canadaguest> the fact that t gauge is a lot smaller than z says something about more modern methods :)
46:22 <canadaguest> but anyway rust_collector as for cheap ng trains, one method (although the tracks wouldn't look quite 'real', for a toy layout noone would ask tho) is to remount ho locomotives onto n scale mechanisms/tracks .. or likewise with g scale body on ho tracks
46:36 <rust_collector> Now, I can see that it is interesting, technically, but.. I don't care. I want to use something usable, and visible
47:07 <rust_collector> yea, I think the HOe uses 9mm, like n
47:41 <rust_collector> I dunno. I already have a lot of ho. it would make sense to use that, but maybe not
48:25 <rust_collector> we will see
49:09 <rust_collector> maybe someone wants to buy my old junk, and I can get a bit of what I feel like. maybe the kids move back in...
49:42 <canadaguest> well find a old (nonworking being a bonus) lgb/playmobil train and have fun with something that looks like a creaky slow skinny "2 foot gauge train" re using ho tracks :)
49:55 <canadaguest> :P
50:27 <canadaguest> btw rust_collector as a side note even marklin did sell narrow gauge trains for a while
50:32 <rust_collector> nah, the point of narrow gauge, is to make it smaller, for me. Well,
50:39 <rust_collector> hmm, yes, they did
50:51 <canadaguest> their "egg-train" series (I forgot exact name if it wasn't that one now) was actually just normal marklin trains but with a bigger body remounted on
51:30 <rust_collector> part of me want the "tt" stuff, (I think it was) IIrc, mostly an east european thing
51:41 <rust_collector> but that is a bit too weird
52:26 <rust_collector> i should take a look at what I have laying around, lol
52:57 <rust_collector> The last train thing I bought, was a roco tram. I have no idea why, but it is pretty neat
53:07 <canadaguest> ah I have seen a bit of tt once in a while and yeah its not quite a very commonplace scale .. even then the fact that theres several major companies (and even some specialized low-volume ones) producing for it just simply confirms that its still a popular one in some groups
53:38 <rust_collector> yes, some of us just like being different, I think
54:57 <canadaguest> rust_collector well if you want 'being different' just ask uk .. they have all sort of weird things going on there (and that many of it is a bit rare outside uk too!)
55:07 <rust_collector> I do want to try the dcc++ things. I have the parts needed... I have no idea about what decoders my trains have....
55:20 <rust_collector> yes, they have their own size as well.
55:22 <rust_collector> oo
55:32 <canadaguest> "fine scale" .. oo9 (whatever that meant) .. etc
55:56 <rust_collector> oo9 is the narrow gauge oo, I think
56:01 <canadaguest> geeze never ever mention 00 .. its a weird "bastardize" of ho :p
56:13 <rust_collector> no, it is just british
56:24 <rust_collector> even their real trains are weird
57:24 <rust_collector> I should probably go outside, and close the car doors. or I will just forget
57:46 <canadaguest> well I mean put an 00 train on ho track ..its fine .. but put 00 locomotive with ho wagon and the two look out of shape with each others
00:22 * canadaguest starts to wonder if creating a digikey account would hopefully actually stop the site from refusing to load consisently
06:57 <rust_collector> we do have a few english spec real trains here. the class 66, I think they were. they looks funny here
07:24 <rust_collector> gm export model. very narrow and strange looking things
07:24 <Halcyon> Morning all
07:53 <rust_collector> they also filled the engine room with snow, so they had to redo the ventilation stuff on them, lol
07:57 <rust_collector> hey Halcyon
08:06 <Halcyon> How's it going?
08:16 <rust_collector> today is a great day
08:38 <rust_collector> I was outside in a tshirt for several hours today. I even mowed the lawn
08:50 <rust_collector> or, "lawn"
09:03 <rust_collector> it is mostly green-ish things
09:12 <Halcyon> You mowed your dirt and weeds?
09:13 <Halcyon> :P
09:24 <rust_collector> weeds and moss, yes
09:39 <Halcyon> Moss isn't too bad, at least it's pretty
09:52 <rust_collector> yes, noce and soft too
11:44 <rust_collector> I really enjoy the new mower. our old one gave up last year. this new one is just so light, so I don't care if I have to push it around. and it is very quiet. I dunno, it is just something about it that makes me enjoy using it, lol
12:38 <Halcyon> I just bought a new one too
12:48 <rust_collector> the old one was nice enough, and it did not have many hours on it. But the cylinder wore out. I guess it was a bad batch of cylinders or something
13:07 <Halcyon> Although I think the new one is heavier, it does have a more powerful engine though. The old one would stall if the grass was too long.
13:13 <rust_collector> but it was heavy and noisy-ish, compared to this one
14:31 <rust_collector> that is what I like about this one, it runs really slow, I guess at around 1/4 throttle. if you push it into some thick stuff, it just throttles up, and gnaws thru. it feels sort of diesel like
15:36 <rust_collector> very torque-y(?) for such a tiny engine.
15:38 <Halcyon> Oh nice
15:54 <Halcyon> Mine just have one throttle setting
15:57 <rust_collector> sounds like a weird vacuum cleaner
16:04 <Halcyon> *has
16:17 <Halcyon> Not like older mowers where you adjust it manually
16:21 <Halcyon> It's either on or off
16:35 <rust_collector> yes, this has... on, and off. but the governor is set in a way that works really well
16:53 <Halcyon> I'll have to test mine out when the grass grows longer
17:05 <Halcyon> I just mowed the other day but only just enough to take the top off and even it out
17:20 <Halcyon> We're coming into winter so the grass is starting to go dormant
17:45 <rust_collector> yes, I am going to raise mine up a bit. i do not want it too short
18:01 <Halcyon> It will help with the weeds
18:33 <Halcyon> I usually cut mine on the highest setting. Its taken a good year or so but it's now at the point where it's thick and lush enough that weeds don't grow
19:19 <rust_collector> meh, nothing kills these weeds. I probably have to dump some nuclear waste on them, but otoh, that could make them even worse, or turn them into spiderman
19:36 <Halcyon> Yeh they are pesky things
20:27 <rust_collector> the other thing, is that thee is almost nothing left for grass to grow in, so I have to think about adding some soil
21:06 <canadaguest> rust_collector btw the uk always had a funny story when it comes to gauges .. especially many steam era stories no less .. like did you know that gwr locomotives could be found to bigger boilers/etc only because of how their tracks were originally broad gauge (till forced to regauge basically)
22:01 <rust_collector> most of my lawn is on top of big rocks, with a thin layer of clay, then a little layer of soil on top. after a few decades, the soil and clay has dropped down between the rocks
22:21 <Halcyon> Yeh you will need to add top soil
22:23 <canadaguest> or these comical stories where for example a locomotive from company A usually turned over its express train to a different locomotive from B at a certain station but one day the B loco didn't turn up so A decided to continue on .. onl yto later end up with its piston striking a platform and being sidelined in disgrace till it could be sent 'back h
22:23 <canadaguest> ome' empty as an oversized load
22:32 <rust_collector> heh, no, I did not know they had broad gauge over there
22:57 <canadaguest> rust_collector well 'Great Western' name not surprisingly was fitting for their 5+ft gauge tracks they tried to impose initially :)
23:53 <rust_collector> Part of me want hitler to have won the war, just because he wanted a super wide gauge train, which should be much better at moving lots of stuff better
24:23 <rust_collector> but, maybe next hitler... we will see
25:36 <canadaguest> rust_collector on a funny sidenote re steam extinctions .. Southern Railway was converting a lot of their network to electrification and even had the locos/emus design to produce but by a twist of fate 1940 happened and most constructions had to stop with some of the major projects having never resumed till well after the 1950's .. which meant a re
25:36 <canadaguest> prisal for many 'southern' steam locomotives
26:02 <canadaguest> SR was one of the early forays into electrics in uk
27:24 <canadaguest> this SR emu was designed in the 1930's just for an idea https://upload.wikimedia.org/wikipedia/commons/4/43/2-bil_emu.jpg
27:33 <rust_collector> ok, why the hell do you know stuff about british trains anyway? what a weird thing to know stuff about
28:01 <canadaguest> well just in general tbh . especially the thing that affected traffics (such as steam>electric transition)
28:24 <rust_collector> seems a lot of the island went with diesels anyway
28:29 <canadaguest> but if you tried ask me about any specific uk diesels I would be like "umm want talk about the engines used in delitic? otherwise I dunno"
28:30 <canadaguest> :)
28:59 <rust_collector> ooh, the napier deltic engines were... also weird
29:31 <canadaguest> although mind you uk did have an interesting flirt with diesel-hydraulic instead of diesel-electric for a while .. sadly when the various companies were unified into a single BR, BR took a sour eye to these and refused to allow newer designs to be created anymore
30:08 <rust_collector> so, how about you telling me a bit about fairbanks morse engines, I like those, just because, and i have never seen one
30:40 <rust_collector> well, the germans have the diesel hydraulics sorted... it is nothing special
31:11 <canadaguest> well yes germany was one of the few countries that did happily develop the diesel-hydraulic for a long time :)
31:16 <rust_collector> hmm, now that i think about it, the southern pacific had a german diesel hydraulic thing
31:21 <EEVBlog> New EEVBlog Retweet: EFF: In a landmark decision the German Constitutional Court has ruled that mass surveillance of telecommunications outside of Germany conducted on foreign nationals is unconstitutional. https://t.co/mjnwnJNgw1
31:25 <canadaguest> especially V200 with its infamous shape (and Y-shaped exhaust ports too)
32:56 <canadaguest> rust_collector I actually know about that specific one weirdly enough ... SP was getting tired of low-power diesels for their mountaineous routes .. so they ordered a small fleet of oversea-spec usa-designed locomotives from krauss (germany yeah) .. and therefore we got the ML4000 which proved that a high-power diesel did exist

33:48 <canadaguest> that did kinda goaded emd (among others) into finally actually producing 2400+hp diesels eventually)
33:51 <canadaguest> :)
34:08 <Oxygene> Bonsoir
34:16 <rust_collector> I do have a thing for gm diesels...
34:21 <rust_collector> mornings
34:37 <rust_collector> I did own one, for a while
35:05 <canadaguest> rust_collector the ML4000 were eventually scrapped due to mechanical difficulties with them (not to mention newer diesels were matching their hp rating more or less) but one of them managed to escape being scrapped by being converted into an unpowered 'locomotive' for training purposes
35:23 <canadaguest> this one lone survivor is being slowly restored to full functional condition as of today
35:32 Quit: Oxygene ([email protected]) Quit: Leaving
36:01 <rust_collector> a weird one, it was a 16-610, iIrc, with turbos. it was fun starting that up, and having it shake its way across the shop floor, lol
36:03 <canadaguest> rust_collector heh gm did have a few odd-looking locomotives .. canada even had a small bunch of one particular gmd locomotive too ..
36:53 <rust_collector> was it 610? 6xx
37:07 <rust_collector> it was not the 567, ans not the 710
37:18 <rust_collector> 6 something
37:18 <canadaguest> rust_collector heres one example from canada https://rapidotrains.com/content/images/gmd1/news61-7.jpg they were basically 6-axle 4-motor "lightweight" shunter/mainline locomotives for the many old farmer networks through canada
37:23 <EEVBlog> New EEVBlog Tweet: Because apparently you can't have a poll and a photo at the same time. https://t.co/fg5GT7fvSG
37:52 <canadaguest> many of them eventually got removed from their original job when most tracks were upgraded or closed down .. so not surprisingly many survivors then end up with only 4-axle 4-motor trucks on them instead (as weight spreading wasn't necessary)
38:51 <rust_collector> for most of the time we had diesels up here, we used a swedish built gm. it was a 2 cab version of the f7, with 3 axle trucks. then we got a version later, with the middle axles not powered
39:39 <rust_collector> https://en.wikipedia.org/wiki/NSB_Di_3
40:05 <rust_collector> we have a few here still, but most are exported, or used for maintenance stuff
40:14 <canadaguest> rust_collector there were actually a few native 2-cab carbody diesels somewhere down southeast usa .. but they were an unique one-railroad oddity tho
40:45 <canadaguest> a lot more common oversea instead .. not to mention the nohab ones (which several are preserved and equally several have that ugly more-boxy modern body shell rebuild)
41:26 <canadaguest> although milwaukee did have a different kind of dual-cab carbody locomotive for a while .. abit electric not diesel ;)
42:04 <canadaguest> here if link still works for you too https://upload.wikimedia.org/wikipedia/commons/thumb/1/10/Avery%2C_Idaho_Little_Joe_GE_electric_locomotive_CMStP%26P_RR_1974.jpg/1200px-Avery%2C_Idaho_Little_Joe_GE_electric_locomotive_CMStP%26P_RR_1974.jpg
42:38 <canadaguest> they were supposed to be shipped to russia but then the embargo happened so all of them were hastily regauged to 4ft8inch and sold to a few usa railways instead .. in both ac and dc forms
42:57 <canadaguest> not surprisingly they were nicknamed "little joe" .. as joe = stalin
44:02 <canadaguest> oh that does remind me I think there was an usa-designed usa-running one in north too ...
44:42 <canadaguest> oh no surprise, it came up quickly. here https://rapidotrains.com/sites/default/files/2016/10/ep5-nh370-800px.jpg :)
44:53 <canadaguest> not sure the history of that one
45:30 <canadaguest> nsb .. why does something sound familiar ...
45:37 <rust_collector> ep5
46:43 <rust_collector> The EP-5s had a reputation for rapid acceleration and high pulling capacity. However, the class also had a tendency to overheat and catch fire due to
46:49 <rust_collector> that sounds fun
48:10 <canadaguest> rust_collector it explains why very little of them were heard during the conrail era as I imagine that lack of maintenance made a lot of them go up in flame :-s
48:38 <canadaguest> funny that conrail kept the one single "rivets" gg1 for a very long time tho
48:46 <rust_collector> it seems conrail can make a brick go up in flames
52:16 <canadaguest> hmm I thought it was nsb but seem not .. there was a northern diesel locomotive I quite liked . even as many of them are being retired for good these years .. it was an all-lowhood one with offset cab .. I think it was for sure diesel-hydraulic as well
57:28 <canadaguest> rust_collector oh it was finland funny enough this I like a lot for some reason http://www.vaiski.net/uudet/dv12jk2.jpg
57:42 <canadaguest> I present you the vr dv12 :)
58:23 <rust_collector> hmm, yes. I think that was based on some russian design... hmm but I am not really sure
58:36 <canadaguest> in passenger gear on the 2-speed transmission they could do 125kph .. surprisingly fast for a little unit
01:00 <canadaguest> rust_collector btw I don't know a lot about the actual class itself but anyhow there used to be one SJ E5 steam locomotive right in canada (till a few years ago when flooding closed the one tourist line and they for some reason decided to sell the locomotives, scrap almsot all wagosn outright, and basically otherwise convert the track into hiking/s
01:01 <canadaguest> kiing paths instead)
01:40 <rust_collector> heh
02:04 <canadaguest> heres the ex-sweden duo in canada http://www.easydestination.net/blogs/wp-content/uploads/2016/03/wakefield-steam-train.jpg
02:51 <canadaguest> the diesel was only used on some days when the train was a particular longer lengths (as the diesel did the shunting at the other station)
03:32 <rust_collector> we use these bastard things now: https://en.wikipedia.org/wiki/NSB_Di_8 they do ok, even if they have clatterpillar engines
04:28 <canadaguest> rust_collector btw if you want something funny to talk about to any usa modellers .. just ask them about the several different small flings amtrak (yes THAT amtrak in usa) had with foreign trains :p
04:36 <canadaguest> let me find a few example photos just for giggles :)
06:00 <canadaguest> https://www.railpictures.net/images/d1/6/3/7/8637.1221733208.jpg thats an danish dmu .. on amtrak :) they nicknamed these things "kiss" because thats what the effect looks like when the air-inflated tubes make contact between two sets
06:40 <canadaguest> and don't stare at this in disbelief as its real https://www.railpictures.net/images/d1/1/5/3/3153.1208702053.jpg .. german high-speed in usa!
07:56 <canadaguest> amtrak "toasters" as they for some reason were nicknamed ... coming from sweden https://history.amtrak.com/archives/amtrak-x995-test-locomotive-late-1970s/@@images/dabd9eee-d892-4023-b397-e077cc17f478.jpeg .. at least this one did directly create a similar-looking american counterpart nevertheless
08:30 <canadaguest> yet another one-off test that never resulted in any similar designs in usa https://www.railpictures.net/images/d1/2/5/0/9250.1050163440.jpg
09:31 <rust_collector> hmm, the toaster thing is based on a swedisc "rc" class. they are pretty good things
11:00 <canadaguest> rust_collector and heres a turbojet trainset, as I vaguely recall they seemingly didn't last long and were basically shoved to rust away if not cut up for scrapmetals https://www.railpictures.net/images/d1/0/3/7/5037.1185339600.jpg at least the more native ones in france/etc had much better lives
11:19 <canadaguest> funny enough these amtrak ones for some reason were complained to cause a "french fries smell" any time they went by a road crossing :)
12:16 <canadaguest> mm I looked it up and yeah the rc class was what implied the creation of the usa-designed emd aem-7 locomotives
12:33 <canadaguest> here if you want them https://upload.wikimedia.org/wikipedia/commons/a/a4/Amtrak_943_with_a_Metroliner_at_Seabrook%2C_MD%2C_November_12%2C_1987.jpg
13:40 <canadaguest> anyway thats all I can recall of amtrak for tonight
13:56 <canadaguest> but yeah you can see that they did literally test a lot of oversea trains for themselves .. the ice one is the most interesting one tho
14:09 <rust_collector> good. ionly remember the fh40, or what they were called
14:22 <rust_collector> not a huge fan of passenger trains
14:38 <rust_collector> https://upload.wikimedia.org/wikipedia/commons/thumb/7/74/IORE_Kiruna.jpg/1024px-IORE_Kiruna.jpg
15:23 <canadaguest> rust_collector the funny thing is that the aem-7 partially existed because the first attempt aka gm e60 was found to have instability problems at high speed that FRA slapped a speed restriction on them making them unsuitable for the corridor trains .. so there
16:49 <canadaguest> for non-electric routes .. well the f40ph was surprisingly very popular (even as many of them had minor rebuilds because it turned out that having HEP off the main engine made them loud at stations, so the rebuild basically moved HEP to its own genset engine)
17:06 <canadaguest> only the gm genesis did eventually replace many of them
18:05 <canadaguest> rust_collector I've seen old and new photos of IORE trains .. always so interesting how its very long string of nothing but just ores .. all days long :)
18:20 <canadaguest> especially that older multi-siderods 3-unit locomotive
19:11 <rust_collector> yes, the dm3 is pretty neat
20:27 <rust_collector> but with the power of the new ones, I sort of get why they replaced them
20:29 <canadaguest> mm actually I remember one more slight unusual diesel locomotive you might like too .. one moment
23:01 <rust_collector> I like these things. one of those was the first engine I tried: https://upload.wikimedia.org/wikipedia/commons/thumb/0/04/Gamle_Vossebanen_Fjordsteam_2018_%28113228%29.jpg/1024px-Gamle_Vossebanen_Fjordsteam_2018_%28113228%29.jpg
23:42 <rust_collector> they had something like maybe 100hp, if you were lucky
24:40 <rust_collector> I think they were rated at 90. but hey, they were fun enough
24:52 <canadaguest> rust_collector these thing were quite asymmetric in an interesting way http://www.railfaneurope.net/pix/at/narrow_gauge/2091/2091_09.jpg luggage/cargo in one "high" hood and single engine in one "low" hood .. and if you had not noticed it actually rests on only two fixed drive axles toward the middle while it had swing guide axles at both outter en
24:52 <canadaguest> ds
25:54 <rust_collector> arrrgh, austria always comes up with something weird
25:55 <canadaguest> even german had a few of these
26:24 <rust_collector> I guess the rails were pretty crap when they were designed
26:33 <canadaguest> rust_collector the only reason I know a bit about it is because .. well .. it doesn't look like just yet another diesel variation .. I mean look at the goofy luggage/engine split in same body shell :P
27:09 <canadaguest> on a small note its surprisingly popular in some model train scales too
27:16 <canadaguest> even lgb has it as well
27:27 <rust_collector> heh, yes, they would
30:44 <canadaguest> btw would you love something weird because it looks like someone took a steam locomotive and un-steam it? :)
31:10 <rust_collector> uhm, no
31:34 <rust_collector> not because of that. maybe for other reasons...
31:52 <canadaguest> I still say yes .. here have fun if you want to try not drop your jaws to the floor https://upload.wikimedia.org/wikipedia/commons/thumb/6/67/Stazione_di_Acqui_Terme%2C_254.jpg/1280px-Stazione_di_Acqui_Terme%2C_254.jpg
32:02 <canadaguest> that was the e.333 (such a consisent numbering)
32:24 <canadaguest> it almost looks like it could use a tender again :)
34:04 <canadaguest> italy sure had many strange 'not simply a boxy shape' electrics early on .. especially when they were using their own 3-phase electrification (before that eventually was converted to single-wire international-friendly universal system instead)
34:29 <canadaguest> but this particular one maybe was the most ugly
35:34 <canadaguest> heh btw I finally had a look .. your GVF 100hp locomotive actually look like someone tried to make their own copy of the german Kof locomotives :)
36:01 Quit: Ysjoelfir ([email protected]) Connection closed
36:15 <rust_collector> yes, except it is maybe even smaller, and has the cab in the middle, and a hood on each end
38:02 <canadaguest> oh tiny reminds me .. I actually like the NS Sik .. it was an interesting low-cost industrial locomotive that was cheap to maintain (especially as it didn't need any coolant fluids for it reused the diesel fuel to cool engine before feeding the fuel pump)
38:04 <rust_collector> i wonder how well the 3 phase stuff worked for the italians. I guess it sort of makes sense
38:16 <canadaguest> I'm a bit more partial to the crane-fitted Sik's but I like both variations tho
40:43 <canadaguest> well 3-phase does have its own quirks tho .. such as only a few "speed steps" by eg varying the cycles or raising/lowering different phases as needed (such as contact only 2 wires instead of 3 for low speed)
41:11 <canadaguest> theres a reason single-wire electrification was the best choice when that was cheap to produce
41:55 <canadaguest> as for ac vs dc with single-wire electrics .. well I don't really have anything to say as both methods worked well
42:09 <canadaguest> russia still depends on dc even for heavy freight trains in middle of russia
43:06 <rust_collector> well, running only one wire also makes sense, but...
44:01 <rust_collector> https://www.youtube.com/watch?v=pguYYjgJCXY
44:01 <canadaguest> if we want talk about multiply conducts .. I don't think there is any better example than the london underground itself :)
44:17 <canadaguest> as far as I recall its the only widely known 4-wire setup
44:24 <rust_collector> weirdos
44:54 <rust_collector> so, that video, it is not because of the video, but I like the model the model is based on
45:03 <canadaguest> I forgot the exact story but I recall that it was because theres one positive and one negative supply rails (on top of the 2 normal rails themselves) because using a single higher positive voltage was problematic in tunnels for some reason
45:17 <canadaguest> that is -200 plus +200 equals 400v .. that sort of supply
46:05 <rust_collector> heh
47:32 <canadaguest> rust_collector and mind you there is also one special maintenance/garbage 'freight' tube train built to withstand two different regulations .. small and squat to fit inside tunnel but then otherwise has standard-height buffers with rigid reinforcements to survive being hauled/shunted by a normal above-ground locomotive
49:24 <canadaguest> rust_collector heh these little swiss thing were basically station shunters although also handled maintenance trains at times .. some diesel some electrics .. still a few in occassional service to today
50:11 <rust_collector> maybe I like them, just because I could probably fit one on my lawn
50:12 <canadaguest> I know a few kitbashed g gauge ones some people have made only because they're suitable models for tiny "3 foot long" bookshelf shunter layouts :)
50:22 <rust_collector> yes
51:21 <canadaguest> rust_collector swiss also had that unusual modern snow rotary which could actually turn itself around just like that .. who ever need "old fashioned track turntables" anymore :P
51:34 <canadaguest> not sure if its been modelled
51:46 <rust_collector> it has
52:01 <canadaguest> oh, just goes to show it seem everyone is modelling almost anything these days :P
52:07 <rust_collector> and we use those up here to . hmm, beilhack, I think they are called
53:54 <canadaguest> rust_collector btw austria reminds me .. I dunno about you but theres something cute about poland narrow gauge that I like .. something about oversized "look at meeeee I'm cute!" kitteneyes-like wide light bezels on them :) http://3.bp.blogspot.com/-6fUXmpuWrXA/U1MGWq-panI/AAAAAAAA-AY/qObQ1l9_Mo4/s1600/PKP+Biskupin+Px38+805.JPG
54:15 <canadaguest> even some of their diesel/electric locomotives still used the same type of 'big' lights
55:55 <rust_collector> https://www.youtube.com/watch?v=RXRvb1Maq1k
57:06 <canadaguest> hmm rust_collector I dunno about you but I wonder if we're getting carried away. I realized we have been talking trains almost nonstop for close to two hours now .. are we nutty or what? :)
57:35 <rust_collector> nah
57:43 <rust_collector> lemon is a nut
59:30 <canadaguest> ok if you say so .. back to more train talks :P
00:37 <rust_collector> ok
00:40 <rust_collector> http://internationalsteam.co.uk/trains/pics02/er02056.jpg
02:07 <canadaguest> rust_collector as for snow clearing .. japan had these unusual things https://i.ytimg.com/vi/IgzHj6WuJ4Q/maxresdefault.jpg basically they took their standard general purpose diesel and mate it with speciality-built plow "cabins" thats suppose to hitch to both ends
02:59 <rust_collector> well, at leas they did not think it was a good idea to use a jet engine...like some people
03:57 <canadaguest> oh boy actually usa had many 'homebuilt' (there was no off-the-shelf plans for them) units that reused ex-aircraft jet engines on a 10kph chassis .. their main purpose was to literally blast ice/snow out of the many turnouts in a busy freight yard
04:54 <canadaguest> at least it replaced the costly slow labrious method of having to manually sweep out each turnout by foot one at a time
05:55 <rust_collector> well, it does not look very fast this whay either
06:30 <rust_collector> We used one like that on a car trailer, to dry the drag strip. it was pretty good at that
06:37 <canadaguest> btw re that japan "set" here is the slight newer version that also could clear three yard tracks at once at lower speeds (unless snow was not too thick to go fast through it) https://i.pinimg.com/originals/7d/3a/8d/7d3a8d289979ebe627ded3f716672ddd.jpg
06:55 <canadaguest> the very long blades gives its wide width ability away
08:25 <rust_collector> the old gm diesel I had, was actually supposed to be used to repower one of the big old "rotary plows" we had. old steam one. They abandoned that idea, so I got the thing for... around $100
09:10 <rust_collector> But that would be pretty cool, if they used that. those things are just so evil
09:31 <canadaguest> rust_collector heh actually usa did have some examples of where old emd B units were stripped of their traction motors and used to drive ex-steam electric-repowered rotary blowers while being pushed by by relatively modern geep diesels
09:47 <rust_collector> if you added some screaming emd noise, that would be cool
09:49 <canadaguest> it was a cheap way to modernize the rotary without having to try shim an engine inside the shell
09:56 <rust_collector> right
10:23 <rust_collector> well, I think up actually did fix up one of the steam ones
10:42 <rust_collector> not sure if it was just for fun, but I think they used it a bit
10:47 <canadaguest> if you're talking about the one used in colorado area .. I think its still always been steam-powered but I may be wrong .. I don't recall a lot
11:17 <rust_collector> yes, it always was, but they fixed it up, so they could keep using it
11:30 <rust_collector> I have no idea where, but that would make sense
11:37 <canadaguest> southern pacific was very big on a lot of specialized (rotary, flanger, etc) units to clear the various lines through the rockies .. and sp being up now up not surprisingly still has several of them
14:42 <canadaguest> rust_collector btw I still chuckle when I share this sort of photo with other people and they are like "really is THAT australia???" https://img.youtube.com/vi/6acPX_00M9Q/0.jpg
14:59 <canadaguest> just because a country is far south and/or full of desert does not mean it can't get too much snow at unusual times
15:53 <rust_collector> meh, you can still see the windows... keep going
17:17 <rust_collector> we started to have a pointy nose on out locomotives, because they could survive being smashed into a pile of snow much better than the flat faced ones, let me see...
18:09 <rust_collector> https://en.wikipedia.org/wiki/NSB_El_16 This one was based on the swedish rc class, like that amtrak one.
18:41 <rust_collector> and this one: several of them
19:44 <canadaguest> heh rust_collector yeah in the early-mid diesel era days in usa there sometimes were funny arguements about how much snow was too much .. some railroads didn't care about slogging at low speed through walkways-blocking deep drifts while others wanted to use plowers when there was more than two feet etc
20:13 <rust_collector> and this: https://en.wikipedia.org/wiki/NSB_El_17
20:47 <canadaguest> I've seen photos of and emd carbody locomotive bringing its train into eg toronto station .. and it has snow all stuck up on top of its hood .. and ice all over the place even on the engine radiators
20:49 <canadaguest> :)
20:57 <canadaguest> and emd=an emd*
21:50 <canadaguest> and the rare steam locomotive with snow all over the top of its boiler? umm better to not ask ... :)
24:38 <canadaguest> rust_collector btw in the day of steam-diesel transition and shortly afterward there were always many interesting stories like for example one railroad had a mix of alco and emd diesels but when serve winter hit the emds were almost always out of service while the alco ones still kept going like as if nothing was happening
25:39 <canadaguest> or another story is specifically to the LIRR .. during the tri-power era (diesel, electric, steam) it transired that some winters the various diesels were often conked out and the electrics had problem with iced up contacts while the 'old reliable' prr-contracted steam locomotives simply kept running
26:51 <rust_collector> the steam things were pretty well figured out by then... and with all the time it takes to even get one going, they better "just work"
27:10 <canadaguest> heh yeah :)
29:26 <rust_collector> just to not mention the 278 points you had to oil every day
29:54 <rust_collector> but, you probably had time to do that, while it was "starting"
31:03 <canadaguest> well self-lubricator and/or roller bearing did replace that on many types
31:20 <rust_collector> to some degree, probably yes
31:46 <canadaguest> although self-lubricators had one problem which a few well known public cases were written about...
31:55 <canadaguest> dry/clogged pipes = hot bearing
32:00 <rust_collector> but I think saying they were low maintenance, is pushing it a bit
33:16 <rust_collector> I mean, even having the self lubricating system work on my tail lift on the truck, once every 3 months or so feels like a miracle
33:47 <rust_collector> it only happens once, after it has been in to get fixed
33:51 <canadaguest> one of these https://www.spellerweb.net/rhindex/USRH/Milwaukee100.jpg was sidelined not due to diesels but because on one typical ran its self-lubricator malfunctioned causing one rod to break off and strike ballast .. its a surprise the train stopped completely on-track after a lengthy emergency brake ... with oncoming diesels there was no interes
33:52 <canadaguest> t in repairing it back to duty
39:46 <canadaguest> rust_collector btw about heavy freight locomotives theres one I kinda like in general .. I'll show you a photo in a moment...
44:13 <canadaguest> rust_collector don't ask about the sky .. this is how I always imagine them hard at work on a heavy train :P https://3.bp.blogspot.com/-i6WECPgzGy8/T3InMKhPu6I/AAAAAAAAA0o/MGaaZaVDHYg/s640/1.jpg
44:27 <canadaguest> they were generally dual unit but there were some other class that had single dual-cab layout instead
45:11 <canadaguest> they were a bit under 3000hp per unit which wasn't bad for 1960's-era 2stroke :)
45:42 <rust_collector> reminds me of that poor old german steam engine living in north korea, running on old car tires
46:12 <rust_collector> i like those things, they look like they were built to do sommething, then they do
48:17 <canadaguest> btw I found it on wiki and seem they also had a 3-unit upgrade variation which basically was just a cabless unit inserted in middle https://upload.wikimedia.org/wikipedia/commons/d/df/3TE10U-0034.jpg?uselang=ru

52:38 <canadaguest> oh rust_collector while checking the russia list I noticed one name I had read about before but forgot about till now .. https://sdelanounas.ru/i/y/3/m/f_Y3M2MTQ2MTcudmsubWUvdjYxNDYxNzcxMC8xYjVjYi9xWnd0bklIMlRGOC5qcGc=.jpeg would you like to guess what that is when it has no pistons? :)
53:49 <rust_collector> eh? some turbine thing?
53:50 <canadaguest> hm sorry wrong link nevermind that one
54:00 * canadaguest stares at the weird search engine clipboard
54:27 <canadaguest> heres the correct one https://www.railwaypro.com/wp/wp-content/uploads/2018/08/Sinara-locomotiva-hibrida-gaz_maxresdefault.jpg
54:35 <rust_collector> weird search engine clipboard....
54:50 <canadaguest> and yes its turbine .. basically a 2-unit locomotive (so yes all traction-powered axles) but one is the fuel carrier while other is the turbine carrier
54:54 <rust_collector> heh, sill some turbine?
55:03 <rust_collector> oyez
55:39 <rust_collector> well, they have gas, and... long distances.... makes sense
55:44 <canadaguest> and heres a different version but still turbine too http://wonderful-russia.net/wp-content/uploads/locomotive-gt-1.jpg not sure if its same split fuel/engine system or not
55:56 <rust_collector> but then, they probably put it in use on the metro
56:03 <canadaguest> I suspect these two are meant to replace the old green diesels on the long distance freights
56:30 <rust_collector> yeah, maybe
57:14 <rust_collector> they sold a bunch of diesels to germany, in the 90s. they were I think much newer than the green monsters
57:31 <rust_collector> and they were certainly not small (or quite
57:37 <rust_collector> quiet
58:32 <rust_collector> https://www.youtube.com/watch?v=rgT4l7LIzao
59:23 <canadaguest> btw russia did make one very funny goof when it came to steam locomotives tho .. one example built and it didn't travel far ... :)
59:33 <canadaguest> let me see if I still knew where a photo of it was
02:11 <canadaguest> http://www.douglas-self.com/MUSEUM/LOCOLOCO/russ/aa20.jpg that thing had seven (yes 7!) rigid drivers .. it split any turnouts it tried to go over ... don't ask
02:57 <rust_collector> who cares? it looks great
02:59 <canadaguest> realistically 5 drivers was a reasonable maximum .. 6 if you had the generious route clearance for it (as up found out with a few specific routes for their one small batch of 6-drivers locomotives)
04:30 <canadaguest> tbh mallets/garratts was the best place for if you wanted a lot of axles under one boiler. in my opinion ;)
04:52 <rust_collector> nah, no one cares. that thing looks just right
05:00 <canadaguest> although even they could have the rare quirky ones too tho. such as a compound mallet that had 2 drivers on the 'low' truck and 3 drivers on the 'high' truck
07:58 <canadaguest> and believe it but africa actually did think about a 8-pistons garratt but it was quietly shelved without any production being started tho .. it would had been uk-like setup with two LP outter and two HP inner pistons at both ends (which would had been like the many uk express locomotives that had the same kind of 2+2 pistons configuration)
08:25 <canadaguest> still wonder what sort of tractive such garratt could had made with the 8 pistons in effect
09:21 <rust_collector> africa....
09:46 <rust_collector> that is a lot of area...
10:37 <rust_collector> https://www.youtube.com/watch?v=XicLQNgyaGk
11:05 <rust_collector> those things do sounds pretty nice, even if they look like they run on gravel and old shoes
13:49 <canadaguest> btw the dutch had some unusual designs like for example this which was made to look un-steam on purpose to blend with road traffics (won't be surprised if horse interactions were involved) https://www.modelrailroading.nl/articulation/netherlands/images/NMVB%20850-851/NMVB%20Garratt%203.jpg
14:19 <canadaguest> or the "not un-steam bodied" version which shared similar drivetrain http://www.modelrailroading.nl/articulation/netherlands/images/LTM%2051/LTM51-2.jpg
14:34 <rust_collector> heh, a tram on steroids
14:37 <canadaguest> thats the only one strange garratt I know of .. everyone else just had the typical ones
15:37 <canadaguest> of course if you want talk about tram steam you need to ask uk .. they had so many of these .. especially the infamous ones classified in the Y group ... heck even the 'toby' engine in thomas movies was based on a Y class too
16:15 <rust_collector> hmm, that was a regular little engine in a box, wasn't it?
17:35 <canadaguest> heres toby without any face :) http://cdn.ipernity.com/135/34/33/25553433.539bc8b5.500.jpg?r2
18:03 <canadaguest> and toby himself http://i1.ytimg.com/vi/T-inc06HmzA/maxresdefault.jpg
18:23 <rust_collector> there was a version without the skirt. I think I prefer that one
19:01 <canadaguest> ah that may had been the industrial/habour version which didn't have to conflict with road traffics as much so the skirting was absent on them per-se
19:39 <canadaguest> there was also another common version which was a bit asymmetric body .. with a lowside water tank and highside cabin sides .. also produced by usa as a wartime measure too
19:47 * canadaguest goes to see if I can find that one
20:32 <EEVBlog> New EEVBlog Tweet: The Moving Goalposts from Free State to Police State by @thevivafrei https://t.co/VPoFiTAHwg
24:08 <canadaguest> rust_collector oh it was a bit unique one in its own right https://d240vprofozpi.cloudfront.net/locos/Y/y1_dept54.jpg .. thats a steam locomotive but not quite in a normal sense .. it was a sentinel locomotive which emant it used their own unusual vertical-like "high pressure supercharged" low maintenance boiler unit driving vertical pistons via ch
24:08 <canadaguest> ain or shaft (depend on design) to the axles themselves
25:15 <canadaguest> heres a preserved working sentinel industrial locomotive https://i.ytimg.com/vi/evsP9OH57bM/maxresdefault.jpg
25:29 <canadaguest> and yeah it looks a bit diesel-like except for all of that smoke coming out of the top :)
26:06 <rust_collector> I like the boxy bckwards looking one
27:47 <canadaguest> this is an africa-exported sentinel design http://www.douglas-self.com/MUSEUM/LOCOLOCO/colombia/col7.jpg and well yeah its small boiler in fact was rated to at least 500psi so it was quite a good output to power the whole thing with
30:04 <rust_collector> what africa?
31:22 <canadaguest> btw if you want something a bit different to look at even less drive this is a dual-cab version of the same 'preserved working' locomotive http://2.bp.blogspot.com/-SCJ6p5_PAEo/T50YQQAf2II/AAAAAAAAAwk/qGjMn4Lq63Q/s1600/Y10+Pic.jpg .. apparently the dockside railway wanted soemthing that would be facing forward in both directions so this was the sim
31:23 <canadaguest> ple solution to that
32:18 <rust_collector> that.... looks convenient
33:26 <canadaguest> and yeah africa did have a lot of unusual trials (one-off's at times) that sometimes never lasted more than one trip .. it was a bit checkered history at times (sometimes with only one or two grain photos as the only evidence left of it too)
33:37 <canadaguest> many times it was an imported design
34:13 <canadaguest> I don't know more than what I just said mind you :)
34:15 <rust_collector> sure, but africa is a bunch of different countries...
34:28 <canadaguest> true that
36:57 <canadaguest> rust_collector oh I remember something I got given once and have probably shared it out one or two times by now so far too .. one sec while I find it again for you
40:14 <canadaguest> rust_collector so yeah guess what happens when you have new diesel locomotives but somehow have to rely on a large fleet of the steam-heated carriages? so rather than making the axle heavy with a big water supply just simply use a small water supply and keep the old track pans in service to refill the water supply enroute http://www.davidheyscollec
40:14 <canadaguest> tion.com/userimages/00001-jrc-chris-carter-40-dillicar-7.jpg
40:29 <canadaguest> thats maybe the only one weird example I know of a non-steam locomotive picking up pan water on fly :)
41:17 <canadaguest> and this photographer has not just one but two examples http://www.davidheyscollection.com/userimages/00001-dh-hest-bank-L.jpg
42:21 <rust_collector> that is neat
43:19 <canadaguest> rust_collector and also he has one thing not many people would had thought of ...
43:57 <canadaguest> it was not only express trains that made on-fly water collect too http://www.davidheyscollection.com/userimages/jrc-black-5-dillicar-troughs.jpg
44:18 <canadaguest> even lowly freight trains apparently can have no time to stop for a water tower
45:12 <rust_collector> it wa probably seriously underpowered, and could not stop

47:41 <Halcyon> Gawd I love Linux
47:46 <Halcyon> Everything just friggin works
47:47 <rust_collector> as you should
47:49 <canadaguest> well actually you need quite some extra power to pick up water .. otherwise the interia of water slamming scoop would quite slow you down
48:08 <rust_collector> what distro are you using, Halcyon
48:10 <Halcyon> Got HiDPI working perfectly in XFCE
48:15 <Halcyon> Pop OS
48:37 <Halcyon> I was using MX Linux which I liked, but Pop has less bundled with it and I find just works nicer in general
48:50 <Halcyon> It also natively supports BIOS/Firmware updates for my laptop
49:50 <rust_collector> ubuntu based... ok
50:17 <canadaguest> rust_collector even then movies-not-photos are a bit rare due to how early it was for any sort of 'low cost' semi-portable videocameras .. but this is a good digitalized one nevertheless https://www.youtube.com/watch?v=DXBJnyjgbGw
50:38 <Halcyon> Yup
50:44 <canadaguest> the second one is interesting because you can see it just starting to scoop
52:09 <rust_collector> I think I will keep my shitty mx-fluxbox, just because I have used mx since 2014.
52:19 <canadaguest> anyway rust_collector I think I want go off for tonight, sleeping soon sorry. was a funny long almost-4-hours trainchat tonight tho :)
52:29 <canadaguest> see you next time ok? ;)
52:32 <Halcyon> Hey canadaguest
52:35 <Halcyon> I mean Cya
52:36 <rust_collector> ok, good night
52:42 Part: canadaguest ([email protected]) from #EEVblog
52:43 <rust_collector> OH! btw
52:48 <rust_collector> aah, too late
52:56 <rust_collector> I was not going to asy anything anyway
53:49 <rust_collector> I do quite like fluxbox, on laptop...
58:16 <rust_collector> I have been digging thru my pile of old isos, and I think some of them deserve to be... if not updated, have their configs stolen, and put on a new base system
59:14 <rust_collector> Maybe especially my favourite evilwm setup, I guess
04:42 <Halcyon> :)
04:53 <Halcyon> I just got a new machine so I thought I'd try something different
04:59 <rust_collector> sure
05:09 <Halcyon> But still like my XFCE interface
05:11 <rust_collector> but then you went for xfce...
05:14 <rust_collector> mmhmm
05:16 <Halcyon> Even on a high spec machine, GNOME runs like crap
06:01 <rust_collector> xfce is just about perfect, if you want a sane desktop, without too much blubber
06:13 <Halcyon> I was thinking about MATE but I have no reason to change
06:35 <rust_collector> well, mate is not BAD, but... nah.
06:53 <rust_collector> I tend to use window managers, or xfce
06:58 <Halcyon> Also, because I'm running everything in 4K, I didn't want to dick around too much, particularly because it's a laptop and I'll be docking/undocking all the time
07:02 <Halcyon> I just want things to work
08:46 <rust_collector> well, you should have enough oomph in that to run some vms, just have fun with it
08:54 <Halcyon> *nod*
10:04 <rust_collector> i remember having trouble, some years ago, when I used a lot of different computers, and tried many distros, and then I installed blackbox in windows7. that messed my head up pretty good
10:32 <Halcyon> What's blackbox?
11:05 <rust_collector> a window manager. it is the grandfather or fluxbox and openbox, and any other xxboxes
11:18 <Halcyon> Ah OK
11:28 <rust_collector> that got pretty confusing
12:17 <rust_collector> open a terminal... no... or did I get the cmd box? I don't remember... alt+p for dmenu, as I was used to... nooooo
13:11 <rust_collector> but yes, there was a few window managers that did work on windows
13:39 <rust_collector> at least 2 of them were versions of blackbox.
13:42 <rust_collector> oh well

14:15 <rust_collector> then I made xfce look exactly like w7, so that did not help
14:42 <rust_collector> I think I even found the intranet exploder icon to put on the desktop
15:05 <rust_collector> I really like that icon, even if it means trouble
23:35 <Halcyon> I've come to love Linux for what is it
23:47 <Halcyon> I don't want it to look or behave anything like Windows
24:06 <rust_collector> says the guy using xfce
24:23 <Halcyon> XFCE is far from Windows
24:29 <Halcyon> It's not even close to Windows 7
24:38 <rust_collector> yes, but it looks close enough
24:50 <Halcyon> Things are clean, in logical places, easily customisable
25:08 <rust_collector> and for most people (like my wife) they can use xfce for weeks, without realizing it is not windows
25:48 <rust_collector> That is... until the printer has changed its ip, for some reason
26:54 <rust_collector> but, otoh, that got me a pretty new yet crap spec laptop to play with, as she went and bought a new one
47:55 <rust_collector> I should have a look at the desktop... it annoys me that the usbs keep turning off.

37:47 <Halcyon> YAY! You're getting it installed today?
37:57 <steve30> yup
38:00 <Halcyon> :D
39:08 <steve30> I had to move the small sofa in the bedroom, and the years worth of junk that was hidden underneath it, and clean ten years worth of dust.
39:32 <Halcyon> Shocking
39:38 <Halcyon> Did you find anything interesting?
40:21 <steve30> nah, i knew what was under there already
40:55 <steve30> AC wise we are having three seperate splits
40:55 <Halcyon> Hahah
41:05 <Halcyon> Each with their own compressor?
41:11 <steve30> yes
41:15 <Halcyon> Very good
41:27 <Halcyon> Are you going to be using it for heating or cooling?
42:03 <steve30> For some reason a multi-split worked out a lot more expensive than seperates.
42:26 <Halcyon> Yeh so you get independent units for cheaper. That's a win.
42:27 <rust_collector> Halcyon, stop asking difficult questions, the guy is getting ac installed
42:33 <Halcyon> :P
42:56 <steve30> The bedroom ones are predominently for cooling. The kitchen one is predominently for heating in winter, although cooling in summer will be a bonus
43:08 <Halcyon> :P
43:24 <Halcyon> I just find it amusing that mid 20's is hot for you guys
43:51 <rust_collector> hahaha... wel, yes
44:00 <steve30> If it weren't for the fact that we have solar power, I'd have probably just had an extra radiator added in the kitchen rather than AC
44:33 <Halcyon> You guys amuse me :P
44:37 <steve30> Halcyon, my bedroom gets intp the high 20s
44:44 <rust_collector> oooh
45:03 <Halcyon> Yeh that's too hot to sleep Steve
45:11 <Halcyon> I like it around 16-18 degrees at night
46:15 <steve30> I tend to like it warm(ish) to sleep. I don't have any hot guys to keep me warm unfortunately :(
46:41 <rust_collector> at least you don't have an ice cold wife....
47:12 <rust_collector> that is something
49:04 <rust_collector> I think I do not really care that much about what temp it is when I sleep, but I have to have something like a blanket, to sleep well. which is annoying when it gets "hot"
49:33 <steve30> I like my electric blanket :)
52:02 <rust_collector> i think it is sort of interesting, it can be a large t shirt, or a towel, or anything. I just have to have something

08:34 <Lemon> we have to wait 48h now, as she was infected by all kind of worms
08:43 <Lemon> if she pass those 48h she'll be fine
08:44 <T3sl4> awww poor thing
08:57 <Lemon> I never saw something like this, she came here with her uterus hanging out
09:08 <Lemon> it happens sometimes when they give birth
09:13 <Lemon> it goes inside out like a sock
09:22 <Lemon> but the problem is that its been a few days
09:25 <Lemon> so it was infected
09:34 <T3sl4> D:
09:43 <Lemon> we never saw her
09:52 <Lemon> but we cant let something suffer :(
09:58 <Lemon> it will probably cost a lot but screw it
10:12 <Lemon> she'll be our 18th cat if she makes it x)
11:04 <T3sl4> good :)
15:12 <hsn93> hi lemon hi t3sl4
15:23 <T3sl4> hey
15:28 <hsn93> sup
16:40 <T3sl4> chilling after optimizing my program some more
16:54 <hsn93> whats ur program :P
18:06 <hsn93> i've sam-ba bootloader utility over rs485 and its hell slow around 3mins to upload 76k .bin file

18:37 <T3sl4> i've got the core reverb section down to 42 + 34*(taps) cycles :)
19:25 <T3sl4> hsn93: 4800bps? o.o
19:41 <hsn93> no, 115200
19:49 <T3sl4> what the fuck
20:02 <hsn93> exactly
20:30 <hsn93> i still dont know why i guess writing from buffer to flash takes time i'll check whats going on
25:02 <hsn93> T3sl4
25:21 <hsn93> how to test this thing ,, it only showed gray window :
25:25 <T3sl4> thing?
25:32 <hsn93> and then disappeared: https://snipboard.io/UtuzhL.jpg
25:57 <T3sl4> hah hmm
26:02 <hsn93> xD
28:31 <T3sl4> what is map.txt? different from level.map?
28:40 <hsn93> i copied it
28:57 <hsn93> level.map = map.txt
29:43 <T3sl4> ok
29:52 <hsn93> its shows loading mouse on gray window and then closes
30:23 <hsn93> https://snipboard.io/BE1A7n.jpg
30:42 <T3sl4> win10?
30:56 <T3sl4> must be something fucky about grabbing a frame canvas or something
31:09 <hsn93> yes win10
31:12 <T3sl4> it works on win7, and... idunno what others
31:18 <T3sl4> try setting compat mode?
31:32 <hsn93> can i do it in cmd mode ?
32:05 <hsn93> it works
32:55 <hsn93> very nice
33:02 <hsn93> how hard to learn this stuff ?
33:35 <T3sl4> idunno
33:46 <T3sl4> windows is bullshit
35:32 <T3sl4> guess i might recommend a wrapper, qt and wxwidgets are popular but as far as i know they're bullshitty too :P
35:42 <T3sl4> so then, uh, just write it in java or whatever :P
44:59 <hsn93> hmm
45:41 <hsn93> qt is bullshitty ?
47:24 <Halcyon> Hey Lemon
47:27 <T3sl4> i'm not aware of any toolkit that supports major GUI OSs (i.e. Windows, *nix) and that has a straightforward, coherent, easy to use interface
48:02 <hsn93> that box is shield ha
48:02 <T3sl4> java perhaps being the closest, but the irony there being you have your choice of 3 or more windowing toolkits, so take your pick, or mix and match who cares :P
50:35 <hsn93> i've no idea how to do this stuff but i enjoyed this before

54:26 <hsn93> yeah
54:30 <hsn93> there is also thecherno

55:13 <hsn93> he got game engine series
56:01 <T3sl4> neat
56:38 <T3sl4> https://www.youtube.com/user/Bisqwit/videos an excellent one
57:41 <T3sl4> he's got a long history on youtube, with cool examples the whole way back
58:12 <T3sl4> not to mention he founded tasvideos.org and was one of the early and prolific TASers on there
01:39 <hsn93> hmm i open one of his video i think i heared this voice before
01:47 <hsn93> https://youtu.be/jnkOcAkLkBU ^ lol this guy is fast
02:56 <T3sl4> helps when your editor playback is literally a TAS itself ;)
04:07 <hsn93> what is TAS a text editor?
08:59 <T3sl4> Tool Assisted Speedrun
09:48 <T3sl4> joe is his own custom editor, which IIRC he's made to record and playback typing and editing, so he can edit how and where code is entered, and play it back at whatever speed he likes
10:04 <T3sl4> so, it's tool-assisted playback of typing :P
12:06 <hsn93> oh nice
12:34 <hsn93> i always thought its long screen record and video editing
12:35 <hsn93> stuff
16:16 <hsn93> lol the glitch : https://youtu.be/RhgSSmBwNf8?t=1045
27:21 <steve30> Halcyon, AC men are here
27:40 <Lemon> back

43:44 <steve30> look like pretty normal vans to me
00:24 <Lemon> hey t3sl4, you might know, I want to build a multi channel voltmeter, 50v input max, mv accuracy/resolution, I planned to use a 8 channel 24bit adc module found on ebay (with integrated Vref) and use a voltage divider. do you think im missing something ? I'll use a random arduino as a uC, and build a little vb/net or whatever program to log data, and a random tft screen to display it.
00:38 <Lemon> https://www.ebay.fr/itm/ADS1256-24-Bit-8-Channel-ADC-AD-Module-High-Precision-Data-Acquisition-Card-BSG/122917917245
00:41 <Lemon> heres the adc module
01:21 <Lemon> for some reasons it seems easy to achieve what I want
01:32 <Lemon> I could even get one more decimal of resolution and maybe more accuracy
01:56 <T3sl4> you'll need some pretty skookum resistors to get there first
02:15 <T3sl4> probably okay, assuming the ADS chip isn't cloned or some shit
02:23 <Lemon> well as it can take 3v max I need like 157k and 10k resistors
02:34 <Lemon> and I guess they need some ok tempco's
02:41 <Lemon> like at least 15ppm, no more
02:52 <Lemon> but if I take them from the same brand/spool they might drift the same way which is good
03:02 <Lemon> and I can calibrate everything with either of my dmms
03:36 <Lemon> but anyway, mv accuracy should be easy no ?
03:44 <Lemon> if better is possible I take it
04:11 <Lemon> I want to use it to measure some stuff like power supplies, various little thingies when I dont want to use a high accuracy dmm on it
05:43 <Lemon> and resistors shouldnt be too important, as long as I have the right ratio right ?
05:47 <Lemon> and tempco isnt too horrible
06:20 <Lemon> that sounds like a cool project
07:45 <Lemon> what is the hard part for you, resistors tempco ?
07:51 * Ampera sneezes at Halcyon 
08:17 <Halcyon> Hey Ampera :)
08:21 <Ampera> how do
08:22 <Halcyon> How are you my friend?
08:26 <Lemon> heyhey
08:36 <Halcyon> I'm not bad
08:38 <Ampera> just woke up, I'm, eh
08:41 <Ampera> alright-ish
08:47 <Halcyon> Got my machine almost all set up
09:33 <Ampera> how is it
09:39 <Halcyon> I love it so much
09:46 <Ampera> hah, gay
09:49 <Halcyon> :P
10:01 <Halcyon> It's so quick, even with games
10:25 <Halcyon> But yeh, running Pop OS now with XFCE
10:35 <Ampera> ew
10:37 <Halcyon> :P
10:45 <Halcyon> It just works
10:53 <Ampera> likely story
11:03 <Ampera> I'll remember that when you ask me for help to unbreak it
11:05 <Halcyon> I don't have time to fart arse around too much
11:24 <Ampera> Sounds like a Windows user to me :P

11:59 <Halcyon> Heh, I won't. Got my various displays all working now. As soon as I undock (i.e.: yank out the thunderbolt cable), the displays automatically adjust to my preferred resolutions, brightness, scaling etc...
12:05 Quit: hsn93 ([email protected]) EOF from client
12:08 <Halcyon> HiDPI works perfectly
12:28 <Ampera> you're probably the only person who thinks that, especially under X
12:56 Join: hsn93 ([email protected]) to #EEVblog
13:07 <Halcyon> From what I read, a lot of the distros are "natively" supporting it now. And so they should. 4K monitors are common
13:11 Quit: hsn993 ([email protected]) EOF from client
13:23 <Ampera> there is no native support, they use the same software as everyone else
13:28 <Ampera> there's nothing special about the distros
13:33 <Halcyon> Every single one of my programs scales properly, even those under Wine
13:49 <Ampera> the problem is that a lot of programs are /not/ made to scale properly
13:55 <Halcyon> *shrug*
14:05 <Halcyon> They seem to work? Maybe I just don't use one of them
14:23 <Ampera> Wayland makes some attempts to improve it, but that basically ends up being making all X programs run at a lower resolution
14:54 <Ampera> A good half of the programs I use, some which are very very integral to how I use my machine, do not support HiDPI
15:14 <Halcyon> Well what works for me, might not work for you
15:19 <Halcyon> And vice versa
15:45 <Halcyon> But so far so good
15:57 <Halcyon> Even better than Windows 10 in that respect
16:09 <Halcyon> I have nothing but dramas with scaling and crap on my work PC
16:10 <Ampera> Someone, some day, maybe me, is going to have to give Window Maker HiDPI support, and then XFE
16:17 <Ampera> those are the two big ones for me
16:34 <Ampera> Oh yeah, Windows doesn't do HiDPI great either, but it does it better than Linux
16:51 <steve30> Halcyon, is this your new laptop?
16:51 <Halcyon> I've had the opposite experience to be honest
17:06 <Halcyon> Windows 10 at work randomly decides to resize windows and text after waking up
17:12 <Halcyon> Steve: Yep
17:24 <steve30> what model is it?
17:25 <Ampera> that's not a HiDPI thing that's a Windows thing
17:31 <Halcyon> Lenovo ThinkPad P1 Gen2
17:42 <Halcyon> Whatever it is, it's fucked
18:09 <Ampera> in general I solve these problems by not usng HiDPI displays
18:29 <Halcyon> I need the resolution though, that's the issue
18:54 <Halcyon> I was using 2560x1440 and it wasn't enough
19:24 <Ampera> what do you need it for
19:24 <Halcyon> And I like tiny font
19:36 <Halcyon> Depends what I'm doing that minute
19:44 <Lemon> pfff true thugs use 5760per 1080 :P
19:55 <Ampera> I mean I agree HiDPI looks great, but it's not worth breaking a bunch of support for programs
19:56 <Halcyon> Can be anything from my personal shit, to uni, to developing courses, to my business shit
20:09 <Ampera> ????
20:15 <Ampera> I
20:16 <Halcyon> As I said, all my programs display fine
20:21 <Halcyon> So far, so goot
20:23 <Halcyon> good
20:48 <Ampera> I'd have to replace my entire desktop environment and file explorer to move to HiDPI
20:54 <Ampera> and terminal emulator
21:01 <Halcyon> Yeh probably
21:09 <Halcyon> As I said, what works for me, doesn't work for you
21:20 <Halcyon> But it beats the shit out of Windows 10 or Mac OS
22:04 <Lemon> also true gangsters use windows 2000
22:20 <Halcyon> Lemon: Agreed, but it probably won't even install on new hardware
22:33 <Lemon> everything is possible with enough time to lose :>
22:49 <Halcyon> :P I tried it with Windows NT, I failed miserably
22:55 <Halcyon> Even in a VM, I only got it half-working
23:04 <Lemon> yeah its a pain
23:21 <Ampera> NT5 installs fine on modern hardware
23:25 <Ampera> it's NT4 that has problems

24:12 <Halcyon> The problem with Win2k isn't the OS itself
24:16 <Halcyon> It's the availability of drivers
24:37 <Halcyon> If you don't mind 640x480 in 16 colours and fuck all else working, then yeh, it runs on modern hardware
24:49 <Lemon> I wonder how accurate the multichannel voltmeter I want to build can be
25:07 <Lemon> I guess the internal Vref and the voltage divider will determine it ?
25:40 <steve30> When I built a new PC in 2010, I didn't really give much thought to the OS. I installed Windows 2000, since that's what I had on the old machine, and found the graphics drivers were non existent
26:14 <Lemon> they really fucked up on that one
26:55 <steve30> I was pretty much intending to use Linux, but ended up dual booting it with WinXP, since 2000 didn't work
27:03 <Halcyon> Lemon: It's not really Microsoft's fault
27:12 <Halcyon> Considering you were installing a 10-11 year old OS at the time
27:35 <steve30> My current PC can't even run Win7, let alone XP
27:40 <Halcyon> You find the same now, Windows 7 support is really lacking
30:11 <steve30> Lots of loud drilling going on downstairs
30:32 <Ampera> I wish someone would drill me
30:41 <Halcyon> Oooh can I be first?
31:05 <steve30> there's a big drill with a big core bit laying on the patio
31:13 * steve30 points it towards Ampera

32:26 <steve30> They'll finish these two units today. He said he may come back tomorrow to do the one in my Mum's bedroom.
34:18 <hsn93> T3sl4 i removed some repeated un required steps now its 2.5 minutes to upload the firmware lol

34:48 <T3sl4> how du?
35:26 <T3sl4> hsn93: it's not, like, trying to flash after every byte/word, is it? that would wear out the flash pretty fucking fast too...
36:27 <hsn93> flash after every word?
36:29 <hsn93> https://snipboard.io/1Mzj30.jpg
36:46 <hsn93> no im writting 1212 pages * 64 bytes ... and issue command to NVMCTRL
37:16 <hsn93> that writes page buffer to flash
38:01 <T3sl4> huh
38:24 <T3sl4> is it a command-response protocol? is it just waiting for a response most of the time?
38:35 <hsn93> yess, thats the issue ^^
39:02 <hsn93> and part of bootloader is written to RAM from boot utility also ..
40:16 <hsn93> i copied it from arduino bootloader https://github.com/shumatech/BOSSA
41:21 <hsn93> https://github.com/shumatech/BOSSA/blob/master/src/WordCopyArm.asm ^^ this thing gets copied at ram and gets called to copy the transfered buffer to the flash

54:03 <hsn93> canada u was talking for 4 hours ?
54:12 <canadaguest> anyhow for anyone still awake now I had to ask if you ever sometimes order a part from a particular company even although their site is quite inaccessible and you're blindly depending on the distributor's description/datasheet alone?
55:04 <T3sl4> not really
55:04 <canadaguest> hi hsn, yeah rust_collector and me somehow managed to talk about trains nonstop for 4 hours .. I was not expecting that (and had to cut it as I wanted to go to bed..!)
55:30 <canadaguest> still don't mind talking more with rust next time I see him but maybe not for as that long again tho
56:22 <T3sl4> so you're saying he's got you well trained ;)
56:26 <canadaguest> t3sl4 np, just had to wonder as theres some parts that only come from a specific company and naturally they refuse to make it accessible website-wise. but mm anyway I'm not going moot too much about this
56:28 <Ampera> Apparently the sears tower lost power and has flooded
57:34 <T3sl4> sears tower, what's that?
59:04 * canadaguest somewhat wonders how difficult a voltage regulator could be to diy
59:43 <canadaguest> ampera hmm any relationship to the now-bankrupted sears clothing/general store chain?
59:56 <Ampera> Yes, it used to be their headquarters.
00:09 <canadaguest> oh, ok
00:11 <Ampera> then it got renamed but no self-respecting person honors that renaming
00:32 <T3sl4> what you talkin bout Willis?
01:43 * Ampera dropkicks T3sl4 beyond the sea
01:52 <canadaguest> amera btw the (or at least one, I dunno if there were ever any others) sears store in ottawa was attached to a small mall and with a third party auto garage on the outside end. the garage was destroyed and dug up due to long-time oil containment .. but the sears part itself was carefully torn down and just a little of the mall roof itself .. appare
01:52 <canadaguest> ntly canadian tire plan to build their own all-glass-enveloped multi-floor shopping store there in that crateful footprint
02:11 <canadaguest> a mall with canadian tire connected to it kinda sounds unusual but should be interesting
03:12 <Ampera> Presumably that's a tire shop
03:21 <T3sl4> just put a couple dozen tim hortons in there and she'll be right
03:27 <canadaguest> btw this is what it looked like not long before being bashed down https://obj.ca/sites/default/files/styles/article_main/public/2018-08/Screenshot%202018-08-22%20at%2007.28.55.png?itok=V-tTo9MU

13:32 * Halcyon prods gremlinz 
13:36 <Halcyon> These guys never talk
13:56 <Ampera> well they don't speak English
13:58 * T3sl4 wallops Halcyon with a message
14:03 <Ampera> they presumably whatever they speak down in Australia
14:07 <Ampera> Australian I guess
14:08 <Halcyon> I read that as "Massage"
14:09 <Halcyon> :P
15:04 <T3sl4> Ampera, how frightful
15:08 * Ampera sends Halcyon on a magic carpet ride
15:21 <steve30> my legs/hips continue to need massages
15:41 <Halcyon> Is that a euphemism for riding your dick and hairy bush?
15:43 <Ampera> T3sl4, makes me think of lushux who is currently and quite often in the hospital, as people keep beating the absolute shit out of him for doing his public art
15:54 <Ampera> and since he lives in Australia he has absolutely no way to defend himself
15:59 <Ampera> because you can't even carry a knife
16:10 * Halcyon sighs loudly
16:34 <Ampera> His life is in constant danger because you jackals just let shit like that happen
16:38 <Halcyon> I'm sorry, COVID-what?
16:47 <T3sl4> Ampera: so what you're saying is, he does asshattery, gets punished for it, and doesn't learn a lesson?
17:08 <T3sl4> spose it's in the blood, whole country of criminals and all
17:11 <Ampera> T3sl4, he doesn't do asshattery, he does public murals, as best as I know with complete permission

22:15 <Ampera> Halcyon, https://www.youtube.com/watch?v=eGkGNCUQtWY
22:31 <T3sl4> the classic
22:32 <Halcyon> Good song
22:45 <Halcyon> They use that in an Aussie movie about the moon landing
23:00 <Ampera> An Aussie movie about some other nation's accomplishments?
23:01 <Ampera> nice
23:02 <steve30> hehe
23:22 <Halcyon> Ampera: It was more about receiving the transmissions
23:33 <Halcyon> Last I checked, the US weren't in position :P
23:55 <Ampera> nice, so you ran the telephone
24:00 <Halcyon> Yep :)
24:07 <Halcyon> Via the Postmaster General's system
24:25 <T3sl4> lady gaga had a song about that
24:28 <Halcyon> That dish still exists today
24:33 <Halcyon> It's a neat place to visit
24:48 <Halcyon> Also a good movie
25:11 <Halcyon> It's called "The Dish", worth watching if you like that kind of thing
25:26 <Ampera> the issue is I can't speak Australian
25:37 <Halcyon> There are Americans in it too, relax
25:45 <Ampera> presumably not speaking English
25:52 <Ampera> or dubbed or something
25:59 <Ampera> I'd watch it with subs but I hate subs
27:31 <Halcyon> Just fucking watch it
27:37 * T3sl4 subscribes Ampera
27:38 <Halcyon> I reckon you'd actually like it
27:47 <Ampera> I'll stick to movies in my own language

30:54 <Halcyon> All I see in the subtitles are English (AU), English (UK) and English (Tard)
32:21 <gremlinz> what should i be talking about
32:34 <Halcyon> *shrug*
32:41 <Halcyon> Just a ping to see if you were still alive
32:58 <Halcyon> One ping only Vasily
42:25 <canadaguest> should you always use a ldo at same/higher voltage or is expecting 5v from eg 4.2v for a bit of time not too unreasonable to ask?
43:39 <rust_collector> are you trying to get 5 volts out of 4.2?
44:35 <canadaguest> rust_collector just curious because sometimes I can't tell where things starts and stops .. "0.6-18v input, adj,3.3,5,12 output" for example
45:46 <T3sl4> look at the part number list, those are different
45:47 <rust_collector> Well, it can not increase the voltage. you need what you want on the output plus a little bit
46:04 <canadaguest> rust_collector thats what I wondered it should had been. thanks
47:28 <T3sl4> any given reg only does Vout = min(Vin - Vdropout, Vset)
48:47 <T3sl4> it might be rated for 0.6-18V in, and whatever out, but actual output is only what's available, up to Vset
49:14 <rust_collector> mmm, coffee
51:32 <canadaguest> t3sl4 and rust_collector hmm actually that one I wasn't sure if was right. is the vdropout basically the minim difference required between input and output?
51:32 * T3sl4 ferrums up rust_collector's dose
51:48 <T3sl4> yes
52:16 <canadaguest> oh so if it has a 1.2v dropout then it'll need 6.2v to make 5v?
52:24 <T3sl4> yep
52:39 <canadaguest> ok that one I probably didn't know :->
52:42 <canadaguest> thaks
52:43 <T3sl4> or maybe less if you're using it at lower current, but if it's that high i'm guessing not much help heh
53:53 <T3sl4> the common source/emitter type ones (actual LDOs, not HDOs that are sold under the same category because lazy) you'll find have a small dropout and that varies roughly proportional to load current, i.e. it has some minimum on-resistance basically
54:32 <T3sl4> e.g. 50mV at 50mA, 300mV at 1A etc
55:14 <T3sl4> no one defines "HDO" but you'll know if there's a diode drop or two in the path, either from the internal diagram, or from the fact that Vdropout is never less than say 500mV even at low currents
55:54 <T3sl4> like old fashioned LM1117 has one diode drop, it's an NPN emitter follower; even older LM317 has two, it's an NPN darlington follower
01:17 <rust_collector> i do wonder if you really want to use this kind of regulator, if you are just running lights and stuff off it.
01:33 <canadaguest> interesting t3sl4
01:47 <rust_collector> I mean, if you want up to 3A out of each
02:11 <T3sl4> 3A is pretty beefy for a lin reg yea
03:02 <rust_collector> I do not know how sensitive your servo things and any other things you have is, but maybe a switching regulator would be better for at least some of the stuff?
03:10 <canadaguest> rust_collector heh 3a is for the bus not for individual loads :)
03:28 <canadaguest> the bus isn't regulated anyhow
03:45 <Lemon> sup thugs
03:45 <rust_collector> yes, so, you want an unregulated bus, then a regulator at each load...ok
03:54 <rust_collector> that is different
04:15 <rust_collector> go on then, lol
04:18 <canadaguest> rust_collector beside most of the larger devices already have wide voltage input so no need to be fancy on the supply side
04:23 <rust_collector> hey Lemon
04:37 <Lemon> waddup ?
04:49 <canadaguest> t3sl4 its likely more in the 100-900ma range btw
04:52 <rust_collector> right. i just assumed things yesterday.
05:04 <canadaguest> rust_collector np mr.trainnut ;) heheh
05:34 <rust_collector> hey, be careful... mr general purpose nut is here now
05:45 <Lemon> mr allthethingsnut
05:52 <rust_collector> yes you are
05:59 <Lemon> also for the multichannel voltmeter, I thought about something for the inputs
06:06 <Lemon> im going to use some screw thingies
06:09 * canadaguest lightly bonks rust_collector with a tender coal scoop
06:10 <Lemon> I dont know the english name
06:21 <Lemon> where you simply put a cable, screw it down
06:32 <canadaguest> lemon thats a spade connector I think
06:34 <rust_collector> a screw terminal?
06:40 <Lemon> yeah a screw terminal
06:48 <Lemon> or maybe screwless if I can find some, like on speakers
07:02 <Lemon> where you put down a clip, put the cable and flick the clip up
07:06 <canadaguest> lemon .. mm speaker is called 'banana' .. don't ask me why
07:07 <rust_collector> maybe a nice... oh... rising block clamp, I think they are called
07:31 <Lemon> yeah if I can find some for cheap that'd be nice
07:47 <rust_collector> meh, not as cheap as speaker terminals
07:47 <Lemon> I earnt 50 euros today
08:00 <Lemon> I fixed two shitty laptops, they needed a cleanup
08:03 <rust_collector> but probably makes much better contact
08:08 <canadaguest> lemon btw re spade connectors theres two types just so you know. one is the forked one with only 3 sides .. and the other is the ring one with 4 sides .. the former some people prefer because it means not having to actually remove the screw but mm yeah
08:13 <Lemon> gold platted copper would be perfect
08:26 <Lemon> ha ok I see, thanks
09:06 <Lemon> maybe I'll aim for 5.5 digits resolution
09:10 <Lemon> and accuracy too
09:13 <Lemon> we'll see
09:23 <Lemon> if its accurate to 100ppm, im happy
09:27 <rust_collector> I think maybe you are crazy
09:34 <rust_collector> but that is ok
09:38 <Lemon> boarf not that much honestly
09:46 <Lemon> it wont cost a ton, and it will be quite useful
09:48 <rust_collector> not that much crazy?
09:50 <canadaguest> looks like I have 49 possible results on digikey (for as long as the site isn't breaking again...)
09:57 <Lemon> its nice when you need to measure tons of things at once
09:57 <Ampera> am I awake yet?
10:04 <Lemon> ho please no digikey
10:12 <Lemon> with the fucking custom fees
10:15 <Lemon> hello ampera
10:16 <EEVBlog> Hello there, Lemon!
10:20 <rust_collector> Ampera, if you are, go back to sleep
10:23 <Ampera> hi Lemon, how are you
10:27 <Ampera> rust_collector, I like your thinking
10:30 <Lemon> im doing good thanks, you ?
10:38 <Ampera> blech
10:41 <Ampera> 190% blech
10:52 <rust_collector> bleach
10:59 <canadaguest> t3sl4 have to ask but does the 'current - quiescant' even matter? thats one more filter I can use on digikey if I want to
11:35 <Ampera> if you ask him any more questions he'll have to start charging by the hour
11:41 <T3sl4> ^
12:00 * canadaguest throws a huge heap of monopoly money over ampera
12:02 <canadaguest> ;)
12:13 <Ampera> I don't need your canadian dollars, sir.
12:15 <T3sl4> you want lower quiescent current, it's just wasted current you can't use; but no need to get crazy about it
12:17 <Ampera> they're worthless here and in Canada
13:00 <canadaguest> t3sl4 yeah most of the values are quite low. still maybe could filter some of that
13:28 <rust_collector> that current is just what the device uses without a load, isn't it?
13:46 <T3sl4> or maybe under load, depends
14:16 <rust_collector> well, what the device uses for itself, without doing anything for you, I guess
14:54 <canadaguest> well I guess this one would be nice to try first then https://www.digikey.com/product-detail/en/on-semiconductor/SCD7812BTG/SCD7812BTGOS-ND/5845500
14:55 <canadaguest> :)
16:20 <rust_collector> that...is a regulator, yes
16:42 <T3sl4> bog standard 7812?
18:15 <T3sl4> ST's version seems to be very slightly cheaper, and rated slightly higher https://www.digikey.com/product-detail/en/stmicroelectronics/L7812CV/497-1452-5-ND/585973 but the SCD is certainly down there
18:44 <rust_collector> well... it will probably work fine. you will need some heat sink if you want some current out of it
19:17 <rust_collector> maybe just use more of them too, they are dot very expensive
19:28 <T3sl4> typical application would be a 15VAC transformer + FWB + filter cap, getting 18-22VDC depending on line and load, then one of those to drop it down to 12.0ish V
20:00 <T3sl4> in turn dropping 6-10V so as many watts at 1A, which will put it into thermal limit even with a quite sizable heatsink
22:28 <Lemon> how can I reduce the tempco problem in a voltage divider ?
24:58 <canadaguest> t3sl4 funny that you mentioned it as I had been thinking a bit about a heatsinked resistor before the regulator seeing that the resistor somewhat has varying voltage output but at least in theory the heat would be split both ways then
25:29 <T3sl4> yeah but then you don't have as much headroom
25:38 <T3sl4> works great if you have excess
27:33 <canadaguest> anyway think thats far enough in here I'll sort the rest by myself so cheers :)
28:53 * T3sl4 honks a train horn at canadaguest
29:02 <rust_collector> meep meep
33:09 <Halcyon> Night all
33:15 * Halcyon licks Ampera
36:07 Quit: Halcyon ([email protected]) Connection closed
37:47 <canadaguest> t3sl4 I know its an unusual special usercase but one way to look at it is that when the current is low the resistor's output is high to regulator but if the current increases the resistor's voltage output drops which lessens the regulator's work. of course this only works as long as the maximum ampere through resistor doesn't result in failing belo
37:47 <canadaguest> w the needed vdropout limit
38:39 <T3sl4> exactly
40:17 <canadaguest> is there a particular name for that kind of component combination or just call it "resistor before regulator"? :)
48:06 <canadaguest> rust_collector anyway don't want to talk nonstop for four hours again but I'll still give you this one tho and let you figure out what to make of it ;) https://upload.wikimedia.org/wikipedia/commons/7/74/David_lloyd_george.jpg
49:05 <rust_collector> you know, those people on top gear had grandparents...
53:41 <canadaguest> and if double boiler isn't enough lets try three http://www.douglas-self.com/MUSEUM/LOCOLOCO/tripleboiler/flaman3x.jpg
53:51 <canadaguest> thats one boiler straddled by two mini-boilers
54:05 <canadaguest> very strange indeed
55:08 <canadaguest> also I forgot what name/number it was rust_collector but santa fe (usa) had one locomotive that was basically one extra long boiler with a complex hinge in middle so it was able to 'bend' around curves
55:30 <canadaguest> I mean how do you bend the many tubes etc .. very weird indeed
04:42 <Lemon> https://www.ebay.fr/itm/CONNETTORE-4-Way-AMP-Stereo-Speaker-Terminal-Plate-Strip-Push-Release-Connector/323935906612?hash=item4b6c15ab34:g:078AAOSwr3BdlVHx
04:45 <Lemon> I thought about those
05:34 <rust_collector> yea, i do not think they are great, but they are pretty quick and cheap
07:52 <canadaguest> rust_collector and just to mix #eevblog and trains together .. heres something electrical https://upload.wikimedia.org/wikipedia/commons/7/71/Chemin_de_fer_Chamonix-Vallorcine_et_le_Mont-Blanc.jpg?uselang=fr that was basically a swiss-french linking line through mountains and since they didn't want to use racks they came up with the unusual concept
07:52 <canadaguest> of every single axles being powered (even on the freight wagons themselves)
08:14 <canadaguest> eventually it turned out that a ratio of 2-3 powered to 1 unpowered was still usable so some wagons didn't have power
08:28 <Lemon> or maybe I'll go with those https://www.ebay.fr/itm/Dual-Female-Banana-Plug-Jack-Terminal-Binding-Post-for-Speaker-Amplifier-New-US/142498840272?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3D858f6f42427943459be89668f07d356e%26pid%3D100675%26rk%3D5%26rkt%3D15%26mehot%3Dnone%26sd%3D303375290457%26itm%3D142498840272%26pmt%3D0%26noa%3D1%26pg%3D2380057%26brand%3DUnbranded&_trksid=p2380057.c100675.m4236&_trkparms=page

08:36 <canadaguest> now the line is still active but only for passengers alone (with special short-chassis extra flexible emu trains
09:13 <canadaguest> thats the only one photographed railway I know of that tried to omit rack simply by using more tractives
13:40 <Lemon> https://www.ebay.fr/itm/1pc-waterproof-plastic-electronic-enclosure-project-box-black-200x175x70mm-F/232977996533
13:42 <Lemon> thats a nice box
14:13 <Lemon> hmmm I think I'll fit the screen and buttons at the front, and banana posts at the back
18:39 <rust_collector> I think bananas are in general better than the speaker clamp things
18:55 <Lemon> yeah and I found a kit of 10 dual gold plated ones for cheap
19:14 <Lemon> https://www.ebay.fr/itm/5Pcs-Black-PB86-A1-6Pin-Red-LED-Momentary-SPDT-PCB-Square-Push-Button-Switch/153424856322
19:16 <rust_collector> but it depends on what you will use as leads, I guess
19:18 <Lemon> I like those kind of buttons
19:24 <canadaguest> rust_collector save for that banana can fall out but the clamp thing not :)
19:30 <canadaguest> so thats why some people still prefer latter
19:52 <rust_collector> well, that is because you get crap ones
20:04 <canadaguest> actually no its pretty much any
20:13 <rust_collector> mmhmm.
20:15 <Lemon> so adc module, 3.5 inch display, enclosure, 8xbanana posts, 5 buttons + 5 led buttons
20:20 <Lemon> thats 58 euros total
20:25 <Lemon> I miss resistors
20:35 Join: hsn993 ([email protected]) to #EEVblog
20:38 <rust_collector> 58 euros, and 34 weeks of work
21:13 <canadaguest> rust_collector tbh I've never seen a retail speaker that included working lock
22:20 <rust_collector> well, he is not making a speaker
22:35 Quit: hsn93 ([email protected]) Ping timeout: 121 seconds
23:36 <rust_collector> but the bananas should be tight enough to stay, and if you yank the wire, I guess it is better if it just fall out, than dropping the box on something?
25:12 <rust_collector> unless he wants to make it nice and fancy, and put a piece of rusty steel in the case, lol
25:56 <canadaguest> hmm had to ask to be sure..how does one figure how much watts a diode would give off?
26:34 <rust_collector> like, how much power it "burns"?
27:52 <canadaguest> yes
27:59 <Ampera> Oh boy I love electric fires!
28:44 <canadaguest> ampera feel free to apply 240vac 20a to a poor little hobbyist 1.5v led then :P
28:51 <canadaguest> heheh

30:22 <steve30> now might be a good time to do some coffee
30:45 <rust_collector> my coffee works great right now
30:47 <canadaguest> rust_collector I mean I know they are not 0w components but I can't seem to recall determining how much
32:00 <Lemon> hmmm with the voltage divider
32:02 <rust_collector> i believe you get it by forward voltage times current?
32:07 <Lemon> the closest I can get
32:19 <Lemon> with 50v max input, is 2.85v
32:22 <Lemon> it can take 3v max
32:30 <Lemon> I think its fine
33:14 <rust_collector> what values did you end up with?
33:32 <canadaguest> rust_collector oh so just vf*i then? hm yeah looks like 900ma through a 1.5v vf probably is a little too warm for free self-mounted
33:35 <Lemon> well I found some 0.1% 15ppm, 300k and 18k
33:42 <Lemon> gives 2.83v exactly
34:38 <canadaguest> 900ma through 400mv vf on other hand is probably nothing .. thats like what a lazy 360mw right?
34:47 <Lemon> and they cost 12 euros total
34:52 <rust_collector> canadaguest, it has to be a pretty chunky diode, to have a 1.5v forward voltage?
35:29 <Lemon> vishay ones
36:04 <canadaguest> rust_collector well its an overkill one heh. 600v 10a maximum .. I was just looking at the variety there were :)
46:28 <canadaguest> rust_collector but did I get 360mw right?
46:46 <rust_collector> uuh
48:09 <rust_collector> yes? i think? urrmmm
