01:05 <Lemonizer> im gonna take a nap buds
01:09 <Lemonizer> I'll see you in a few !
01:17 <rust_collector> have fun
07:04 <rust_collector> Ysjoelfir, are the variacs and isolation transformers sort of common down there?
07:42 <rust_collector> I usually do not find any up here. but otoh, I do not really need them.
07:46 <Ysjoelfir> not realy, I just always wanted one, ma father did, too, and suddenly we had three variacs and two isolation transformers on our desks
08:01 <rust_collector> oh ok
08:11 <Ysjoelfir> and when my father dies I suddenly had three variacs and two isolation transformers on my desk
08:16 <Ysjoelfir> *died
08:21 <Ysjoelfir> he already did that
08:53 <rust_collector> I wonder what kind of crap I will end up with when my parents log out
09:30 <rust_collector> mom has tons of music gear. I don't know what I would do with that
09:54 <rust_collector> dad... I am not sure if he has anything. he has a lot of books
10:03 <rust_collector> and an old tv
11:14 <rust_collector> But who knows, maybe he has a valuable collection of... uhm, furry handcuffs and rare buttplugs.
11:21 Quit: Lemonizer ([email protected]) Ping timeout: 121 seconds
12:03 <Ysjoelfir> XD
12:16 <Ysjoelfir> or furry buttplugs!
12:25 <rust_collector> possibly
12:52 <rust_collector> or rare butt-cuffs? just to make the list complete
13:44 <Ysjoelfir> :D
13:46 <Ysjoelfir> Oh
13:49 <Ysjoelfir> Lemonizer!
13:55 <rust_collector> he left
13:56 <Ysjoelfir> Interested in a guitarr?
13:59 <rust_collector> no
14:01 <Ysjoelfir> arr
14:06 <Ysjoelfir> damn
14:37 <rust_collector> I hope mom will sell her music stuff before she goes
15:32 <rust_collector> I don't know what to do with that stuff

20:30 <rust_collector> hmm, dad has a clarinette, from the 1880s. it sounds horrible, but it looks nice
22:16 <Ysjoelfir> My gf wanted to learn the clarinette. I always wanted to learn bagpipes
24:01 <rust_collector> I can play the "h" note on a clarinette. just close the top valve
24:39 <rust_collector> and that is all I can remember
25:34 Quit: JoePublic ([email protected]) Quit: http://www.kiwiirc.com/ - A hand crafted IRC client
25:36 <Ysjoelfir> that is infinite percent more than I know about it
29:13 <rust_collector> Hmm, do you know the little plastic "flute" things, that we use on the 17th of may up here? just a plastic tube with a reed
29:31 <rust_collector> pwiiiiiiiiiiiiii
30:10 <Ysjoelfir> does it sound as awfull as it reads?
30:14 <rust_collector> yes
30:23 <rust_collector> it is just annoying
30:44 <rust_collector> pwiiiii pwiiiiiiiiiiiiiiiiiii pwii pwiiiiiiiiii IIIIIIIIII!II!!!!!
31:16 <rust_collector> anyway, if you tape that to a tuba, and feed it with a compressor, you get some pretty impressive noises
31:53 <rust_collector> Now, bagpipes... that is just weird, why would you want that?
32:37 <rust_collector> I did try that a little bit, but I think I just do not have enough interest in it, to make it work properly
32:39 <Ysjoelfir> who would try that?
32:54 <rust_collector> bagpipes? I have no idea, lol
32:55 <Ysjoelfir> bagpipes... well... i like the sound and it is something unusual I think
33:01 <Ysjoelfir> no, the tuba thing :D
33:06 <rust_collector> well
33:11 <rust_collector> uhm
33:21 <rust_collector> it has to be tried
33:44 <rust_collector> when you have all the things laying around, it is hard not to try
35:58 <rust_collector> I think the tricky part of bagpipes (for me) was that I do not play flute, which a bagpipe pretty much is, but ok. The tricky part is to keep refilling the bag, while you are pressing it with your arm, so ie pushing air out of it
36:47 <rust_collector> I ended up just making random noises for 4 seconds, then it was empty, and I had to start over
41:36 <Ysjoelfir> I expect that to be my experience as well :)
41:47 <Ysjoelfir> even though I once played flute pretty decent
42:03 <rust_collector> that will probably help a lot
42:28 <Ysjoelfir> but also, before learning the bag thing, you train using a practice chanter. what is basically the flute from the bagpipe with an added mouth piece to replace the bag
42:47 <Ysjoelfir> and its also WAAAAAAY more silent than the whole bagpipe
43:06 <rust_collector> ah, yes, that sounds like a good idea
55:36 Join: hsn ([email protected]) to #EEVblog
56:13 <rust_collector> I would probably recommend just staying with that, and forgetting the bag
59:32 <Ysjoelfir> but then you wouldn't have the chord pipes playing
59:48 <rust_collector> exactly
01:48 <Ysjoelfir> that would be kind of boring, wouldnt it?
02:37 <rust_collector> nah, it would sound like you were playing a flute, I guess, which is a big step up from the noise from a bagpipe
08:00 <Ysjoelfir> xD
08:03 <Ysjoelfir> I like bagpipes...

08:13 <rust_collector> we all have out issues
08:58 <Ysjoelfir> hehe
14:20 <hsn> why the disclaimer :D
14:48 <rust_collector> I think... you did the german thing there... and I do not like it
15:26 <Ysjoelfir> because I am a little scaredy cat^^
16:36 <rust_collector> having a disclaimer is fine, but don't write blahblah horrible regime. Just say this is a thing from back then, and you will be offended if you want to
17:56 <rust_collector> But, that is a pretty cool looking little radio
18:07 <Ysjoelfir> you are right. what do you think about it like that?
18:15 <Ysjoelfir> the disclaimer i mean
18:36 <steve30> Apparently my Chinesium has departed Dongguan, Guangdong.
18:36 <rust_collector> better
18:54 <rust_collector> what did you order, mr steve?
19:12 <steve30> New foam ear pads for my headphones
20:27 <Ysjoelfir> brb, hunting for food
20:36 <Ampera> I have to get up and go do things
20:43 <rust_collector> oh no!
20:44 <Ampera> but getting up and going and doing things requires getting up to go do those things
20:51 <Ampera> and I don't want to get up and go do things to get up and go do things
20:56 <rust_collector> crap
21:42 <rust_collector> Do what steve does, and stay curled up in a duvet
22:16 * steve30 wraps Ampera up in a cosy duvet
22:22 <Ampera> I don't own a duvet
22:30 <Ampera> all I have are blankets
23:04 <steve30> blankets are good too
23:18 <Ampera> I need to do laundry
23:40 <rust_collector> NOOOOOO!!!!!!
24:09 <hsn> appearantly (https://www.eevblog.com/test22) random names after '/' is redirecting to eevblog 404 .. but if u put (names of real folder u get ngix 404 page .. is that (very small security revealing info) ?
24:24 <hsn> like https://www.eevblog.com/.well-known
24:42 <Ampera> no not really
25:21 <Ampera> well
25:22 <Ampera> eh
25:54 <hsn> but there are crawlers that look for folders ? u might forgot somthing open to public read ? or ?
25:58 <steve30> I have to go and pick up my Mum's prescription tomorrow. She's moved to a surgery which I had a falling out with a few years ago, so I hope I don't have to engage in any discussion with them.
26:45 <Ampera> a surgery?
26:58 <Ampera> I presume you mean a chemist
27:03 Quit: Halcyon ([email protected]) Ping timeout: 121 seconds
27:08 <Ampera> No! Not Halcyon!
27:26 <rust_collector> quitter
27:38 <steve30> no, I pick the prescription up from the surgery, then take it to the chemist
28:30 <Ampera> In American parlance, a surgery is an operation not a place
28:34 <hsn> quietter ?
28:56 <Ampera> so unless you've had a falling out with the actual operation she's having, and have to go to the actual event to pick it up
29:49 <rust_collector> in up here, the guy who writes the prescription will just send it to the chemist, so it is ready when you get there to pick it up
30:20 <Ampera> here they're called pharmacists, and aye
30:28 Join: Halcyon ([email protected]) to #EEVblog
30:37 <Ampera> picking up a prescription here means you pick up the actual medication from a pharmacy
31:05 <Ampera> it /can/ mean you pick up the physical paper prescription, but they're so rarely done
31:11 <Ampera> only time I ever got a prescription was for epipens
33:25 <steve30> I might see about going back to having my Mum's sent electronically to the chemist
34:27 <steve30> With electronic prescriptions, you are kind of tying yourself in to one chemist. The advantage of a paper prescription is that you can take it anywhere with no hassle.
36:20 <rust_collector> In my case, the doctor is in the second floor of the pharmacy, so it really does not matter much. But I can just tell him to send it to xxx location, or ask for a paper version, if I am going somewhere
38:04 <Ampera> here I'm fairly sure you can just call your doctor's office and have them send it somewhere else
38:10 <rust_collector> otoh, I do "not need" medication, so it is not a thing for me.
38:34 <rust_collector> yes, same here
42:44 <coppice_> steve30: what's wrong with using one pharmacy? If you are away for a while they can make arrangements for you
43:21 <coppice_> paper prescriptions mean going to the doctor's surgery to pick them up
44:29 <Ysjoelfir> I cought some Burgerking!
44:36 * Ysjoelfir is proud. and not hungry anymore
48:04 <Ysjoelfir> so whats the difference between a duvet and a blanket
48:34 <rust_collector> a duvet is a bag of fluffy stuff, and a blanket is a blanket?
49:24 <rust_collector> but I am sure it means something completely different in some places, lol
49:26 <steve30> I normally go to a pharmacy several miles away from home. Occasionally it is more convenient to go to one closer. Also, with my Mum's, there can be the need to shop around as she like to get a specific brand for one of her tablets.
53:45 <coppice_> steve30: why would you use a far away one, when there is a close one?
57:04 <steve30> For starters, some of the local ones are owned by Bestway panacea Healthcare or whatever they are calling themselves now, whom I had a falling out with.
57:41 <Ysjoelfir> Bestway Pancake doesn't sound to bad to me?
57:59 <steve30> The town centre one I go to has nice staff who know me well as a patient, he charges me very reasonable prices, they don't keep me waiting, and are convenient for visiting when shopping.
08:20 <Ysjoelfir> guys, I am realy having problems with my restauration. I can't find a modern alternative to the ancient tube style resistors. which is... pretty logical. but I can't think about a way to get a visual simmilar thing like those.
08:26 <Ysjoelfir> any ideas?
08:50 <rust_collector> what does a tube style resistor look like?
09:24 <Ysjoelfir> wait a sec
11:35 <hsn> guys i've few questions ,, the transformers used in (SMPS) are pulse transformers? if not, is'nt bad for power efficiency to have these fast switching filtered by the transformer?
13:52 <Ysjoelfir> tube resistors and a standard quarter watt resistor as size comparison
13:52 <Ysjoelfir> https://drive.google.com/file/d/1HB0TQ8MDxm1e3dvTeC6iAPNeNOlMpuQ0/view?usp=sharing
16:47 <Ysjoelfir> I thought about getting small pieces of whatever tube and printable heatshrink... but what about the thicker parts on the end, the flat contacts,...
16:54 <Ysjoelfir> I'm not sure if that will look good at all
19:27 <steve30> I'm sure I've seen that 'style' of resistor available today. They're probably high voltage or high precision types or something.
19:27 <coppice_> hsn: I don't think you understand how an SMPS works
19:47 <rust_collector> are they tubes, with a resistor inside, and end caps pressed on?
20:14 <hsn> coppice_ i've general idea but me too :D
20:40 <coppice_> hsn: if you had any idea how they worked, you wouldn't have asked your question
21:09 <rust_collector> and Ysjoelfir how out of spec are these things?
21:19 <Ysjoelfir> it's a tube with resistive material coated onto the outside, end caps pressed on and dipped into paint and after that, marked.
21:35 <Ysjoelfir> they are dead. between 30 and 280%
21:41 <Ysjoelfir> +-
21:41 <rust_collector> yay!
21:54 <rust_collector> that is interesting
22:24 <Ysjoelfir> the material they used is just carbon dust, its a nightmare in regards of stability in every way
23:10 <Ysjoelfir> i mean, the 100k is at 280k and a 3 meg is at ~1.2M....
23:19 <rust_collector> I think I would try to get the end caps off, and probably drill a hole, or make a slot in each end, to poke regular resistor leads out of that, then put the caps back on
24:25 <Ysjoelfir> that would be the way I think to go. BUT: some of them are >1W... so no chance to get a modern resistor into that
24:51 <rust_collector> maybe you could print the markings on cardboard, and roll into a tube, and use the old end caps?
24:59 <rust_collector> coat in clear
25:18 <coppice_> resistors of that type are probably at least 70 years old. by the 60s most resistors had wires comming out of the middle of each end, and the few which which were built to be radial no longer looked like that
25:29 <rust_collector> how about 2 1/2w resistors, with the leads sneaking past the other?
25:49 <Ysjoelfir> that could work rusty, maybe I will try that.
26:11 <Ysjoelfir> coppice_: true. those are from the radio I posted before, so... dated 1938 or earlier
28:34 <rust_collector> otoh, all the people who know what they used to look like are dead, so you could probably make them a little bit different, lol
29:52 <coppice_> I know what they used to look like, and I'm not speaking from beyond the grave
30:40 <rust_collector> we can block you, I guess
31:52 <Ysjoelfir> XD
39:58 * rust_collector is looking at a video about making stairs... I do not need to make stairs
44:41 <coppice_> is it a 12 step program?
45:10 <rust_collector> I am on video #17. i don't think so
45:18 <rust_collector> we will see
00:37 <Ysjoelfir> who was this guy with the nice headphones again? rusty? Iirc you linked to that guy?
02:59 <rust_collector> simply put
03:28 <rust_collector> he made the weirdest video today
04:08 <rust_collector> https://www.youtube.com/watch?v=GbdgoWs4vMY
04:45 <Ysjoelfir> thanks :) i forgot to subscribe before and couldn't find him again
39:34 <rust_collector> I do wonder what happened, to make him post the latest video. it is just weird
57:17 Quit: hsn ([email protected]) Ping timeout: 121 seconds
58:15 <Ysjoelfir> that is indeed a good question
05:07 <coppice_> what is weird about it?
06:33 <rust_collector> making a video about making a mains to croc clip cable?
07:01 <rust_collector> Well, I dunno, it is just not his usual kind of thing. I would expect that from some guy in india
07:20 <coppice_> oh, I thought you meant the video you linked
07:55 <coppice_> which seems very main stream for youtube - a muddles explanation of maths
11:12 <rust_collector> that video I linked, was just to show his ears
12:34 <coppice_> "Hagrid goes off at a tangent"
12:39 <rust_collector> hah

15:57 <Lemon> erf I think I'm sick
16:24 <rust_collector> I told you so.....
17:44 <Lemon> not this sickness :>
18:04 <rust_collector> mmhm
18:08 <rust_collector> we will see
36:06 <Lemon> I hope I'll receive the wavetek tommorow
36:12 <Lemon> I can't wait to play with it
48:14 <Lemon> I need to sell my laptop
48:42 <rust_collector> again?
48:49 <Lemon> no its still not sold
48:56 <rust_collector> sell a picture of it
49:06 <Lemon> heh
49:14 <Lemon> I want at least 750 euros out of it
49:16 <rust_collector> signed, and numbered. 1 of 200
49:31 <rust_collector> well, good luck with that
49:52 <Lemon> those models sell for around 800 something usually
49:57 <Lemon> mine is like new
50:04 <rust_collector> whateverrrrrr....
50:09 <Lemon> :>
50:17 <Lemon> you know what that means if I sell it
50:28 <rust_collector> the thing is that you have to sell it, so you will get 600
50:43 <Lemon> ho theres nohassle
50:49 <Lemon> id go down to 700 but no less honestly
51:00 <rust_collector> if you got a new one, and won the lottery, someone would give you 1000
52:33 <Lemon> yeh thats always like this
56:27 <Lemon> hehe I just found a nice stand for the multavi 5
56:37 <Lemon> I feel clever
57:00 <rust_collector> ok, make a clever pic?
59:18 <Lemon> https://imgur.com/a/G4CRp8M
59:39 <Lemon> its a stand for a portable screen
00:56 <rust_collector> that will work
01:06 <Lemon> pretty stable heh
03:56 <Lemon> the systron is really neat
04:09 <Lemon> stable, not even warm to touch
04:12 <Lemon> zero noise
04:24 <Lemon> it lacks autoranging but heh no big deal
04:37 <rust_collector> it should not really need a lot of power, so...
04:38 <Lemon> I also love the display, its really readable in night time
04:51 <Lemon> ho you know the keithley is kinda warm
06:20 <Lemon> theres something I really think is fascinating
06:23 <Lemon> variable capacitors
06:31 <Lemon> I have two I found in destroyed radios
07:51 <rust_collector> I took one out of my old alarm clock/radio.
08:06 <Lemon> they are so cool and satisfying to turn
08:13 <rust_collector> I do not get anything useful out of it, which might be why the radio never worked, lol
08:25 <Lemon> ho they rarely die I think
08:36 <Lemon> I mean
08:38 <rust_collector> I think this one can pre-deaded
08:39 <Lemon> what could go wrong ?
08:45 <Lemon> besides a mecanical break
09:06 <rust_collector> yeah. they should be fairly reliable
09:30 <Lemon> I also salvaged some parts from a microwave, the big cap, transformer, big diode, some micro rupters etc
09:36 <Lemon> the cap is impressive
09:42 <Lemon> like 2.5kv 1uf or so
10:02 <Lemon> they can handle much more
10:06 <rust_collector> 2.5kv is on the low side for a micro, isn't it?
10:18 <Lemon> theres like 4kv in fact in it
11:28 <rust_collector> right
11:42 <Lemon> if you shake it you can hear the oil in it
12:48 <rust_collector> I have been looking for old microwaves, because I need a pair of transformers, but when I find one, I can not be bothered to take the whole thing home, and I do not feel like taking it apart where it is
13:10 <Lemon> usually I take them home, take what I want and put them back

30:38 <Lemon> I wonder how are those variacs https://www.ebay.fr/itm/Metered-Variac-Sortie-AC-Variable-Transformer-2-Amp-0-250V-TDGC2-0-5KVA/262812370335?hash=item3d30d6859f:g:Gt4AAOSwrL9dvhx4
32:03 <rust_collector> that would work for me, but do not expect too much from it, I think?
32:23 <rust_collector> I mean, it is a transformer, and lightweight?
34:04 <Lemon> I want one for the case of an old thing that im unsure about, to slowly bring it to nominal voltage and see if theres a huge current draw or not
34:20 <Lemon> it shouldnt need a huge precision I mean
35:30 <rust_collector> no, that is not a problem. I would be more worried about the thing bursting into flames, but otoh, it is probably using wires thin enough to just burn out before anything bad happens
35:49 <Lemon> yea thats a bit worrying
36:08 <Lemon> ho I will see honestly I don't need it now, I'll just wait to find one for 20 euros on leboncoin
37:15 <rust_collector> yeah, pre-smoked
37:27 <Lemon> knackered
37:33 <Lemon> like we love them
37:39 <rust_collector> yep
38:22 <rust_collector> Ok, I just watched 5.63 videos about emacs
38:57 <rust_collector> I feel slightly dizzy
39:02 <Lemon> im falling asleep
39:32 <rust_collector> I can give you a link, if you want to be sure you fall asleep
40:20 <Lemon> ho I think I'm ju st going to see my bed
41:17 <rust_collector> I should do that too, I just have to make sure I blacklist anything about emacs on my network
41:27 <Lemon> so theres some wavetek waveform gen that are 5mhz max selling for 150-200 euros
41:37 <Lemon> 300+ for some 20mhz ones
41:51 <Lemon> im really happy about mine,cant wait to get it
41:59 <Lemon> 100 euros for a 30mhz one with tons of function was a steal
43:43 <Lord_of_nothing> Hi

20:08 <Ampera> it's impressive how you can simply decide to just say, I ain't going to work today
20:37 <Halcyon> That is what sick leave is for. I have over 1000 hours of it accrued.
21:01 <Halcyon> And if you leave a job, you don't get it paid out or transferred. So may as well use it when you're sick.

27:57 <T3sl4> just finishing up the butterscotch-chip cookies i made last week
33:56 <Halcyon> Oh nice
10:44 <Ampera> Halcyon, we're talking about men in afternet
10:55 <Halcyon> That's nice :)
11:06 <Ampera> hows your birb
11:14 <Halcyon> Jerry's good
11:23 <Halcyon> I just cleaned his cage. Mark went to buy him new toys
12:22 <Ampera> I gave Zoey celery
12:34 <Halcyon> Your rabbit?
12:43 <Ampera> No my hedgehog
12:50 <T3sl4> aww
12:54 <Halcyon> Aww you never told me you had a hedgehog!
13:01 <Ampera> Because I don't have one
13:05 <Halcyon> Damn
13:08 <Halcyon> They are cuuuute
13:18 <Ampera> so are you
13:20 <Ampera> why would I need more than that
13:26 <Halcyon> Nawww :)
13:51 <Ampera> your sense of personal freedom is barbaric, but that's just a blemish on an otherwise perfect peach
14:07 <Halcyon> Hah, you're in a very nice mood
14:08 * T3sl4 squeezes Ampera's peach
14:15 <Ampera> I wish I had a peach
14:28 <Ampera> some melons too
14:46 <Ampera> add a bean to salad as well
15:45 <Halcyon> Hahaha
17:15 * Halcyon plays with Ampera's buns
18:15 <Ampera> sometimes I think our friendship is just an excuse for you to eventually turn me into some sort of perverted sex slave when I come visit you in Australia
18:26 <Halcyon> ......
18:37 * Halcyon slinks off to lock the sling room door
18:39 <Halcyon> Nothing to see here
19:01 <Halcyon> :P
19:09 * T3sl4 grabs the key, swallows it
19:20 <Halcyon> That's part of the game T3sl4 :P
19:22 <Ampera> Does your house have a basement?
19:29 <Halcyon> No, basements are rare here
19:37 <Ampera> That's a shame...
19:46 <T3sl4> if you want it back you'll have to do a cleveland steamer
19:49 <Halcyon> I wouldn't mind one, but it would flood quite often
20:16 <Halcyon> Most homes here are built on concrete slabs and piers
21:22 <Ampera> Do you at least have a shed?
21:36 <Halcyon> No, I have no need for one
21:40 <Halcyon> I keep stuff in the garage
21:50 <T3sl4> it's not healthy to gayrage
22:01 <Halcyon> Sheds are fairly common though, but they scare me. Spiders and snakes go in there
22:16 <MrMobodies> Hello, I have two sheds
22:25 <MrMobodies> One wood, and one brick
22:35 <Ampera> Brick you say...
22:39 * T3sl4 poops in the brick one
22:51 <MrMobodies> yes, the top is flat
23:09 <MrMobodies> it has windows too, at the back of the garden
23:17 <MrMobodies> but they are single pane
24:02 <MrMobodies> it is leaking though
24:18 <Ampera> We have a couple of wood sheds, but the issue here is you can only keep people in them when it's not winter
24:24 <Ampera> because it gets deadly cold out
24:26 <DHess_US> If your house doesn't have a basement, then were do you keep the bodies?
24:30 <Halcyon> MrMobodies: Ampera just wants to be tied up in one for sexual gratification
24:39 <Halcyon> DHess_US: I back onto bushland :P
24:48 <Halcyon> Like my backyard is literally bush
25:00 <T3sl4> wow that sounds horrible
25:06 <T3sl4> don't your bfs shave or anything?
25:12 <Halcyon> Hahah
25:30 <MrMobodies> There is a convservatory too... but not heating in there not good for winter like now
26:16 <MrMobodies> that village pub across the road has a basement for barrels
26:52 <Halcyon> The other difficulty with building a basement where I am is that the ground is literally made up of sandstone. It would cost a lot to dig it all out
28:16 <T3sl4> upside, don't need a foundation, just seal the walls against leakage
30:00 <Ampera> Halcyon, now we're talking about brutal and violent death in afternet
30:02 <Halcyon> We wouldn't want to you seep T3sl4
30:12 <Halcyon> Right up your alley Ampera
30:36 <T3sl4> mancomb seepgood wouldn't feel welcome there
41:16 <Halcyon> Jerry says hi
42:00 <Ampera> hi jerry
42:12 <Halcyon> Wow, this is the gayest straight guy I've seen: https://www.youtube.com/watch?v=RbcqfIneLsc
42:18 <Halcyon> He also says "you guys" too much

24:58 * steve30 purrs
25:00 <Halcyon> \o/
25:16 * Ysjoelfir falls to sleep while listening to the purring steve
25:27 <steve30> aww
26:07 <Ysjoelfir> I always fall asleep when i'm sitting on the sofa and one of the cats decides that my crotch is a great place to lie down and start purring
26:18 <T3sl4> holding you hostage
26:23 <Halcyon> Hahah
26:24 <Ysjoelfir> kind of
27:14 <Ysjoelfir> ok, not like, instantly, but if I am relaxed and listen to the purring... its so calm :)
27:21 <Ysjoelfir> and peaceful
27:24 <steve30> I like purring cats
27:33 <Halcyon> I prefer rain
27:47 <steve30> Halcyon, say Hi to Jerry for me :)
27:49 <Ysjoelfir> I love rain, too, especially when it hits the roof windows.
27:51 <Halcyon> He is here
28:29 <steve30> Hi Jerry
28:38 <Halcyon> He has been a butthole today
28:46 <Halcyon> We are thinking of getting him a friend
29:47 <Halcyon> We were looking at a princess parrot today
31:07 * steve30 pets jerry
31:17 <hsn> hi,,
31:27 <Ysjoelfir> Who is jerry? :D
31:28 <Ysjoelfir> Hi hsn
31:44 <steve30> Halcyon's cuddly friend
31:56 <Halcyon> Ysjoelfir: Our cockatiel
32:24 <T3sl4> Halcyon, you're a cock
32:28 <Halcyon> :P
33:40 <steve30> We've had a lot of wind here recently. I always get paranoid when we have wind due to me having solar panels
34:19 <Ysjoelfir> aww :) can it sing?
34:20 <Halcyon> They're fine
34:25 <Halcyon> Nah he just chirps
37:38 * steve30 meows at Halcyon 
37:54 * hsn makes lion sound 
38:03 <hsn> i dont know english word
38:06 * Ysjoelfir is silently working
38:12 <Ysjoelfir> roaring hsn ;)
38:27 <hsn> raw ring
38:39 <Ysjoelfir> https://www.youtube.com/watch?v=CevxZvSJLk8
40:56 <Ysjoelfir> don't ask me why this song came to my mind :D
41:06 <hsn> because of roar name
41:12 <hsn> word*
42:14 <hsn> Current NAND devices implement the “Chip Enable Don’t Care” feature. With this feature, the controller can de-assert CE# in between commands in the same command sequence. Also, the ALE and CLE signals are ignored if CE# is de-asserted. This approach allows the memory controller to eliminate the latch glue logic for lower cost in gates and less overhead in CPU cycles, and to allow code shadowing from NAND to RAM.
42:28 <Halcyon> Awww Jake is so cute: https://youtu.be/8ebhA0PY05Y?t=148
43:09 <hsn> i dont understand, (glue less logic) .. ? whats the problem with (old chip enable) ?
43:32 <hsn> that the cpu need to keep (CE) desserted so waste of cpu cycle as nand is much slower ?
44:41 <hsn> does jake know what he says?
44:56 <Halcyon> I guess so? Parrots are clever
46:06 <T3sl4> hsn: does it specify a "command sequence" as /CE asserted all the time?
50:25 * steve30 climbs over Halcyon 
50:50 <steve30> I'm in a 'playful kitty' mood this morning :D
51:06 <Halcyon> Stupid cat
51:07 <Halcyon> :P
51:41 <hsn> T3sl4, as much as i understand .. old NAND without (CE dont care) stops reading operation when cpu stops pulling CE down ..
51:46 * T3sl4 stabs Halcyon, scritches steve30
51:55 <steve30> :)
53:56 <hsn> https://community.cypress.com/docs/DOC-9237 <--- in the diagram they have shaded areas for (Chip dont care) ..
55:02 <hsn> is it only for (multiplexing) where u need to communicate with other chips so u need to make the CE high and send commands on same bus to different chips ?
57:02 <hsn> becasue other wise i would think .. this feature is useless i would just keep CE low all the time .. if finished dealing with the chip i will just pull it high again .. ? so useless feature.. ? but for sure i dont understand why you would need to pull it high in shadded areas
57:28 <T3sl4> well, CE is always for multiplexing
57:59 <T3sl4> i'm guessing it's something about hanging onto state between CE assertions
58:37 <T3sl4> like if you need to read from RAM (during which the flash won't be addressed i.e. CE deasserted) inbetween accesses
59:12 <T3sl4> alternately, it might be to simplify single chip situations, where you don't have anything else on the bus
59:28 <T3sl4> tho that's probably the opposite of what's needed so nvm
01:47 <hsn> like if you need to read from RAM (during which the flash won't be addressed i.e. CE deasserted) inbetween accesses << thats my assumption also.. but not sure .. i never used RTOS so i dont have that mentality yet :P
02:27 <hsn> im so scared to do 2 accesses xD
04:01 <T3sl4> just do it, and if it doesn't work, don't do it :P
05:34 <hsn> im researching before schematic and pcb design .. to far from coding stage !!
06:12 <hsn> i want to have (https web server on next board) big jump for me on both hardware and software ..
06:46 <T3sl4> can always put in 0-ohm jumpers so you can reconfigure it easily later
06:52 <T3sl4> if it's a layout thing at all, even
10:43 <hsn> hmm i'll when i know how to draw the schematic .. thanks ..
24:51 <Halcyon> Mew
25:52 <T3sl4> µ
26:03 <T3sl4> wait, why are you mewing?
26:06 <T3sl4> Halcyon, stupid cat
26:26 <Halcyon> Because I'm stupid
28:29 <T3sl4> the fuck is beeping outside... at this hour? *looks*
28:48 <T3sl4> hahaha wow, someone must've parked in apt parking, and the tenant called in a tow
28:57 <T3sl4> someone's going to have a sad morning
29:00 <T3sl4> but a just morning
29:02 <Halcyon> Horns should come with a subscription. Each press charges the owner of the car
29:04 <steve30> hehe
29:55 <T3sl4> it was the tow truck backing up
34:18 <hsn> reminds me of india mombai trafic lights
34:26 <hsn> horning ^
34:36 <Halcyon> Heh
35:08 * T3sl4 honks at Halcyon
35:16 <Halcyon> :)
35:23 <T3sl4> https://i.imgur.com/4LSTgzU.png
35:34 <Halcyon> Hehe I like that game
38:12 <hsn> https://www.youtube.com/watch?v=KIgKvUPXeq4&feature=emb_title << this one
38:20 <hsn> the honking punish
38:57 <Halcyon> Oh gees
39:08 <Halcyon> I love how drivers just have no fucking idea
39:21 <T3sl4> i wonder if people will gamify that by honking or revving as they drive thru greens
39:30 <T3sl4> thus keeping it open for longer, DOSing cross traffic
39:51 <Halcyon> ROFL. I love that idea
39:56 <T3sl4> assuming it's real, even; that vid is heavily cut, it's not apparent that it even works at all, or at all the way they present it
40:11 <hsn> lol
40:17 <hsn> it was in the news ^
40:32 <T3sl4> you believe all news all the time, right? :P
40:55 <hsn> no, just saying its not just video .. idk
41:00 <hsn> xD
41:17 <Halcyon> I don't get the mentality of people who use their horn, as if it's magically going to make traffic flow
41:23 <Halcyon> I'd just give them a ticket
41:59 <hsn> it makes some people act faster,, my self when some one behind me horns .. i stop
42:08 <hsn> and wait
42:16 <hsn> and he get scared then i move
42:17 <hsn> again
42:52 <T3sl4> yep
43:24 <Halcyon> There should a timeout on car horns, it allows you to honk for 3 second every minute. Exceed that, you get locked out for 5 minutes and your car is limited to 60 km/hr
43:25 <Halcyon> Hahah
43:38 <Halcyon> People would quickly learn
44:25 <hsn> thats awesome .. no need to lock speed.... lock gears into 3rd ..
44:33 <Halcyon> Hahaha
44:50 <Halcyon> And if you keep pressing, it just keeps dropping your speed
45:16 <T3sl4> wouldn't work on my manual transmission :P
45:30 <Halcyon> How fecking old is your car T3sl4 ?
45:36 <T3sl4> 95
45:42 <hsn> T3sl4 nothing works on u anyway
45:45 <hsn> xD
45:50 <T3sl4> :D
45:56 <Halcyon> I guess you could just retard the timing or something? I'm assuming it still has an ECU
46:11 <T3sl4> ye
46:17 <hsn> lock the clutch on manual ?
46:30 <T3sl4> and stall the engine stopping?
46:45 <T3sl4> or, do you mean open it
47:04 <Halcyon> I just think traffic penalties should be harsher even for the "minor" offences
47:16 <Halcyon> It keeps respectful people on the road and the selfish fuckwits off it
47:30 <T3sl4> not nearly enough officers around to watch that much, tho
47:46 <T3sl4> and most "minor offences" we have around here are automatic cameras
47:51 * steve30 watches a Dave video on LBRY
47:55 <Halcyon> We have mobile phone cameras now
47:55 <T3sl4> which are a clusterfuck of legal chicanery
47:58 <Halcyon> Which is excellent
48:52 <Halcyon> If I had it my way, ever intersection would have a red light camera
48:58 <Halcyon> There is just no excuse
49:02 <Halcyon> *every
49:12 <T3sl4> Halcyon: over here, you have to be accused by a witness
49:21 <T3sl4> most of our traffic cams are owned by corporations
49:33 <T3sl4> which somehow get to write tickets on behalf of the civil authority
49:36 <T3sl4> but not
49:42 <steve30> Whenever I accidentally go through red lights, there always seems to be a police car in the vicinity :S
49:49 <T3sl4> if you take it to court, it's thrown out instantly -- you have no accuser
50:02 <T3sl4> but scheduling the court date takes twice the cost of the ticket
50:12 <T3sl4> murka, land of the hidden cost
50:29 <Halcyon> Yeh over here, private organisations cannot issue fines. Only Police, Government Agencies and Council rangers
50:40 <Ysjoelfir> Oh, I read my - as a german - favorite word, traffic penalties <3
50:55 <Halcyon> Also photographic/video evidence is the best evidence
51:15 <Halcyon> Unfortunately it's what the courts expect these days
51:51 <hsn> i'd one that had very short (yellow light) i'd to research about recommended yellow light duration for road speed
52:30 <Halcyon> All out light changes (from green to yellow or from yellow to red) is a minimum 3 seconds
52:37 <Halcyon> Larger intersections are longer
52:51 <hsn> it was less than that
53:00 <hsn> i wouldnt stop on that highway
53:07 <hsn> full of heavy vehicles
53:22 <Halcyon> Sorry from green to red is a minimum 3 seconds
53:30 <hsn> less. .
53:41 <Halcyon> Even then the red light camera doesn't kick in until a short time later
53:49 <hsn> there was actually road speed vs (duration)

54:05 <Halcyon> Like point to point?
54:36 <hsn> it was obvious in the video that if i stop it will be hard brake
55:02 <Ysjoelfir> I would love them (the penalties) to be higher.... Its so... nice, if some new bmw sports car or whatever tries to battle you because your 98 big station wagon seems so slow and sluggish... when the light gets green, I just accelerate as normal, the 165 HP from 2.3 liter kicking the old volvos butt, and the bmw with its 1.2 liter 120 HP motor tries to keep up, reving up as hell, nearly pushing you off the road when he just doesn't
55:02 <Ysjoelfir> get in front of you.... that cost you 25€ in germany.
55:07 <hsn> idk ,, it was 80km/h .. traffic changed very fast my estimation <2 seconds from green to red
55:59 <steve30> I should pop out, back later
56:04 <Halcyon> Have fun
56:12 <Ysjoelfir> hafe fun popping steve :)

00:47 <Ysjoelfir> I have a SLI set flypping around for ages.. I guess over 10 years now
00:51 <Halcyon> It could be nice to have two of the same
00:56 <Ysjoelfir> I'm not sure what mine are though
01:13 <Ysjoelfir> I remember one of them being a Diamong? with three green heatsinks?
01:18 <Ysjoelfir> *Diamond
01:30 <Halcyon> Yeh Diamond Multimedia were popular back then
02:29 <Ysjoelfir> If you want I can take a look what mine are this evening. I have also two different ones, and maybe one fits one of yours, so we could swap?
03:00 <Halcyon> Sure :)
03:20 <Halcyon> I never actually had a working SLI set up
03:28 <Halcyon> I always lusted after it but it was too expensive
03:51 <Ysjoelfir> I had. Combined it with a... a.... erm... how was that strange thing called...
04:02 <Halcyon> Which strange thing?
04:03 <Ysjoelfir> the first card ever to only render what you actually see
04:22 <Ysjoelfir> I cant remember the name
04:24 <Halcyon> No idea?
04:32 <Ysjoelfir> wait a sec, I want to find that out now

51:13 <Lemonizer> I really cant wait, so much functions :>
51:21 <T3sl4> i managed to destroy the outputs, and replaced the special RF transistors with generic audio transistors, so unfortunately its output isn't the full 10ns rise/fall time it's supposed to be :P
51:25 <Lemonizer> its a 30mhz sweep/pulse gen too !
51:33 <Lemonizer> awww
51:34 <T3sl4> nice :)
51:37 <Lemonizer> how did that happen ?
51:42 <hsn93> so now im using secure connection from HexChat .. can ISP know im chatting with u guys ?
52:01 <T3sl4> beats me, IIRC i was driving a transistor base, so, just a near short circuit load

53:24 <Lemonizer> spectrum ?
53:32 <hsn93> spectrum analyzer?
53:34 * steve30 hugs Halcyon 
53:39 <hsn93> or was it function generator ?
53:40 <Halcyon> I made a toasted three cheese sammich with hot english mustard
53:42 <Lemonizer> no no I just said, like, I need to learn how to not destroy them :> because I bought many things those last weeks
53:45 <Lemonizer> but im still learning
53:57 <Lemonizer> and no I dont have a spectrum analyzer :> im about to receive a waveform gen today !"
54:15 <Lemonizer> well a sweep/pulse/waveform gen
54:20 <Halcyon> I put too much mustard on though
54:38 <T3sl4> mmm, mustard
55:05 <hsn93> i got shrimps for luanch
55:16 <Halcyon> Mmm shramp
56:03 <Halcyon> https://www.youtube.com/watch?v=V7mf55p1wA8
56:37 <T3sl4> mmm, mustarded shrimp

56:42 <hsn93> <T3sl4> mmm, mustarded shrimp
56:50 <hsn93> who was here just watching this video for absolutely no reason?
56:51 <hsn93> ^^
56:54 <hsn93> first comment
56:56 <Halcyon> *shrug*
57:13 <T3sl4> absolutely no raisin*
57:36 <hsn93> shruawg
01:39 <Ysjoelfir> mmm, raisins
01:46 <Ysjoelfir> but not with mustard and shrimpels

40:48 <hsn93> i wounder if i ll get them
44:45 <Lemonizer> you will
44:59 <Lemonizer> I ordered hundred of items on ali, I rarely had issues
46:29 <Ysjoelfir> but not while they coronated, did you?

46:48 <Ysjoelfir> I already saw that, its hilarious :D
46:56 <Lemonizer> well I got some stuff recently, everything is on track
47:03 <hsn93> i like how he gave up
48:16 <Ysjoelfir> did someone of you ever happen to asked for a custom voltage divider from caddock, vishay or whatever? eg. T3sl4, DHess_US or coppice_?
49:10 <T3sl4> nah, haven't needed one
49:44 <coppice_> what is a custom voltage divider?
49:56 <Ysjoelfir> meh. I'm struggling to find information about minimum amounts and pricing...
50:26 <Ysjoelfir> coppice_, like that: http://www.caddock.com/Online_catalog/Mrktg_Lit/TypeVMN.pdf but with specific resistances/ratios.
50:30 <Lemonizer> im sure it will be with many digits
51:01 <T3sl4> what do you need, that can't be made from COTS?
51:08 <Ysjoelfir> cots?
51:29 <hsn93> silly naming of cats
51:37 <T3sl4> commercial off the shelf
52:00 * T3sl4 ties up hsn93 with string made from catgut
52:03 <coppice_> oh, you just mean custom resistor hybrids. You don't usually need to buy vast numbers, but they can be pricy.
52:10 <hsn93> :D
52:13 <Ysjoelfir> ah. I never tried putting a cat as a voltage divider in mains circuit. they don't even work on battery powered devices all to great... :P
52:37 <T3sl4> they're... eh, usable in organs
52:40 <hsn93> we have a saying (cats have 7 souls)
52:51 <hsn93> so they survive for 7 cycles
52:55 <hsn93> 6*
53:41 <coppice_> Hybrids can work really well for things like dividers, as the resistors can temperature match really well, and have a very good overall temp coeff
53:41 <T3sl4> curious
53:49 <T3sl4> we have that, but we say "cats have nine lives"
53:53 <Lord_of_nothing> Hi
53:57 <T3sl4> o/
54:04 <Lord_of_nothing> I love cats that much!
54:09 <Lord_of_nothing> The are damn cool.
54:15 <Ysjoelfir> lol :) regarding COTS: Iiiiii personally would just use two discrete, more or less precise but stable resistors. but the head of development thinks a hybrid would be waaaaay better and cheaper in regards of calibration
54:16 <coppice_> cats have 9 lives but 0 souls
54:22 * T3sl4 meows at Lord_of_nothing
54:42 <T3sl4> cheaper in what kind of quantity
55:49 <hsn93> ours -- 2 gone because of desert heat ..
55:52 <hsn93> xD
56:07 <coppice_> people rarely use a hybrid for cost reasons. its normally for performance
59:12 <Ysjoelfir> that is his thinking:
00:38 <Ysjoelfir> we need to measure source flicker with an uncertainty of .2% on four channels (L1,2,3 + N) simultaneously. IF I use just standard resistors, lets say, .01% with low tempco, We would have to check 8 resistors for accuracy. If I use hybrids we could just assume they are good. which I don't aggree with.
00:55 <Ysjoelfir> and additionally we are talking in numbers of.... 5 a year?
01:04 <Ysjoelfir> eg 20 calibrations
01:25 <Ysjoelfir> I'm not very confident that this is the way to go for this application.
01:34 <coppice_> the use of hybrids has no effect on calibration requirements at all
02:14 <T3sl4> 0.01% is the design value, innit? what drives cal anyway
02:21 <T3sl4> qual dept i suppose
15:53 <hsn93> oooooh aaaa,,, dance for me dance for me dance for me
17:11 <rust_collector> moin... you
18:00 <Ysjoelfir> I think so too. But how can I convince him?
18:14 <Ysjoelfir> Well, maybe if I find a price that sais "nope!"
18:15 <rust_collector> use them
18:51 <Ysjoelfir> I like hybrids, no question asked there. But why should you use a unneccesarily costly part if just two discrete Rs do just fine?^^
19:13 <Ysjoelfir> Hi rusty
19:24 <rust_collector> you should, to keep mr boss happy for now, then he can find out it makes no sense later
20:37 <Ysjoelfir> I already asked our..... erm.... "buying department" to get a quote. usually we get precision Rs from Isabellenhütte, but they were directly like "erm..... no."
20:58 <rust_collector> well, then it is no longer a problem, is it?
21:23 <Lemonizer> Ysjoelfir, gimme a good idea of a beginner circuit I could breadboard with basic passive component kits, like some caps, resistors, transistors, diodes etc
21:28 <Lemonizer> I want to learn !
21:42 <Ysjoelfir> Multivibrators!
21:55 <Lemonizer> alright lemme google it
21:57 <Lemonizer> thanks !
22:16 <rust_collector> wifevibrator controller module.
22:31 <Ysjoelfir> I knew that this will come, rusty :P
23:21 <rust_collector> wifi or bluetooth, I don't care. you can use ethernet too, as that thing runs on mains anyway
23:59 <rust_collector> just so you can have an app
24:55 <Ysjoelfir> another thing he drives me nuts about is a thermal problem. We have big power resistors in that product. In the previous, 25 year old version (which NEVER got thermally tested!) those are just bolted to the bottom of the case. When I made my measurements I already assumed that this will get pretty hot (4 resistors, 3x heating with ~76W and 1x with around 50W), so I advised to just use a big heatsink, bolt the Rs onto that and put a
24:55 <Ysjoelfir> fan beside it.
24:58 <rust_collector> how about a boost or buck converter?
26:08 <rust_collector> are those 2w resistors?
27:43 <Ysjoelfir> He assumes that this will be to expensive (I did not assume but I checked - 27€ per heatsink) and instead advises me to just use double the resistors in parallel to enlarge the surface between resistor and case. But this won't do anything in regards to the thermal problem - we now have two resistors with half the wattage, putting their heat into the same chassis, which would result in exactly the same, wouldn't it? also, four
27:43 <Ysjoelfir> additional resistors would cost around 36€...
27:48 <Ysjoelfir> no, 100W :)
28:52 <rust_collector> so, ie you just want to keep the chassis cooler?
30:31 <rust_collector> how long does such a device run anyway? is it one of those things that you just install and use forever?
30:56 <Ysjoelfir> I want to keep the resistors AND the chassis cooler, but mostly the first. the chassis can be kept cooler by other methods.
31:06 <rust_collector> or do you do shorter tests, and smile and go for lunch?
31:32 <Ysjoelfir> It's a reference impedance that simulates the impedance of the mains grid. you usually do tests that last about 2 hours with that.
31:43 <rust_collector> ok
32:08 <Ysjoelfir> speaking of lunch: I'm gonna have that now. get something to eat to keep myself from getting angry :D
32:20 <rust_collector> too late!
32:40 <Ysjoelfir> true ;)
32:49 <rust_collector> I feel it is nice to be back home. not working while other people are at work
33:11 <rust_collector> I just had breakfast
33:14 <Ysjoelfir> Usually I enjoy work, but some things are just.... raaaaaah!. You know what I mean?
33:20 <rust_collector> yep
33:29 <Ysjoelfir> :)
33:36 <Ysjoelfir> however, I'm off for lunch. brb
34:22 <K> hello
35:10 <hsn93> hello to you K
35:11 <EEVBlog> Hello there, hsn93!
35:38 <hsn93> Hello there, EEVBlog!
35:57 <rust_collector> hello, allthepeople and mr bot
36:31 <hsn93> going down to check what my college is doing
36:47 <rust_collector> is it moving?
51:48 <coppice_> don't you know every object is stationary, and its just every other object which is moving?
57:00 <Lemonizer> Ysjoelfir hmmm so I made the circuit, a basic astable multivibrator, but for some reasons it works at first, but leds quickly start to dim then light off
58:00 <Lemonizer> I used two 2n3904
58:38 <rust_collector> does it restart, if you power off, and back on again?
59:21 <Lemonizer> I have to wait a bit first
03:04 <Lemonizer> ho wait
03:08 <Lemonizer> I might have found my error
04:00 <Lemonizer> yes it works
04:13 <Lemonizer> two 10k R's were placed wrong
04:31 <rust_collector> great
04:48 <rust_collector> now, as that works now...
05:01 <rust_collector> what can you use that for?
06:27 <Lemonizer> hmm I could fire up the scope and observe outputs
06:45 <rust_collector> sure
08:09 * Ysjoelfir returned
08:51 <rust_collector> mayb elook at what happens when you turn the voltage up and down?
09:30 <Lemonizer> hmmm when I probe a led, I get nothing
09:49 <rust_collector> do they stop blinking?
10:48 <Lemonizer> probe with the scope I mean
10:52 <Lemonizer> it doesnt interfere
11:00 <Lemonizer> if I take the voltage down to lets say
11:13 <Lemonizer> 4v
11:15 <Lemonizer> it stops
11:20 <rust_collector> it would
11:25 <Lemonizer> but at one moment both are lit up
11:32 <Lemonizer> ha yeah it goes faster
11:44 <rust_collector> does the shape change?
12:23 <Lemonizer> I get nothing on the scope
12:28 <Lemonizer> its either not stable or idk
12:42 <Lemonizer> lemme probe a cap
13:42 <Lemonizer> hmm no I dont get anything interesting at all
13:51 <Lemonizer> it should be some sort of square wave no ?
14:26 <rust_collector> I don't think so, on the cap
14:39 <Lemonizer> where should I probe then ?
14:43 <rust_collector> where is you scope ground?
14:45 <Lemonizer> I tried caps, resistors, transistors etc
15:05 <Lemonizer> on the collector of one transistor that goes to the negative side of the supply
15:19 <Lemonizer> emmiter
15:20 <Ampera> it is morning
15:21 <Lemonizer> not collector
15:25 <Ampera> I hate all of you
15:32 <Lemonizer> understandable
15:34 <Lemonizer> have a nice day :>
15:36 <Ysjoelfir> I love you too, Ampera :)
15:38 <rust_collector> we hate you too, Ampera
15:43 <rust_collector> or something
16:13 <Ampera> I'd believe rust_collector before I believe Ysjoelfir
16:23 <Ysjoelfir> :O
16:40 <Ysjoelfir> Don't trust the norwegian guy, that is a bad thing! trust the german, nothing can go wrong there!
16:42 <rust_collector> as long as it is not about science stuff, I would too
16:52 * steve30 returns (again)
16:52 <Ampera> Ysjoelfir, tell that to the french
17:17 <rust_collector> the french pretends to not understand, there is no point
17:21 <Ysjoelfir> xD
18:05 <Ampera> what happens when you boil down the essence of humor
18:09 <Ampera> laughing stock
19:29 <coppice_> I thought that's what you get by stewing a hyena
20:15 <Ampera> stewing a live hyena might be quite funny
20:46 <coppice_> I doubt the hyena would get the joke
20:59 <rust_collector> I want to watch you stuff a hyena in a pot
21:27 <Ampera> coppice_, might still be laughing about it though
21:40 <coppice_> you need to stuff pot in the hyena first, to get it more mellow

40:54 <rust_collector> always a good sign
41:04 <Lemonizer> wait, you arent the pc repair guy of the house ?
41:09 <Ysjoelfir> x
41:15 <Ysjoelfir> xD its still not done?
42:06 <rust_collector> it is in again, it was here for 2 days, then we sent it back
43:37 <rust_collector> and Lemonizer I do not fix half year old things, when I can send them back, and have people do... nothing for a few weeks
43:52 <Lemonizer> understandable yes
45:51 <Lemonizer> so my systron donner dmm got ranges labelled like 1/10/100 etc
45:54 <rust_collector> anyway, it turns out they did nothing since last wednesday, but they were going to send it to the repair department right now, lol
46:00 <Lemonizer> but it seems its in fact 1.3, 13 etc
46:16 <Lemonizer> heh usual stuff
47:21 <rust_collector> I guess that is nice, that you have a bit "extra" on top, just if you are close to the next range?
47:45 <Lemonizer> yes that is really nice in fact, I can measure a 10v reference for example
47:56 <Lemonizer> without losing a digit if its at 10.0001
48:05 <Lemonizer> but its strange
48:19 <Lemonizer> usually its by tens
48:25 <Lemonizer> like either 10, 20, 30 etc
48:27 <Lemonizer> not 13
