16:29 <rust_collector> hmm, I have to move the piano today. If I think about it a bit more, it will turn into a big project

28:44 <hsn93> guys .. 16x2 vs https://www.digikey.com/product-detail/en/newhaven-display-intl/NHD-C12864A1Z-FSW-FBW-HTT/NHD-C12864A1Z-FSW-FBW-HTT-ND/3767469
29:01 <hsn93> is 16x2 more rigid and will last ?
31:39 <hsn93> last more
38:28 Quit: Ysjoelfir ([email protected]) Quit: Farvel og har en hyggelige tid :)
42:35 <T3sl41> put it in a bracket and it's just as rigid?
43:05 Join: Stiff ([email protected]) to #EEVblog
44:47 <hsn93> then why we see 16x2 very common in industry .. isit just because its simpler?
45:07 Nick: hsn93 is now known as hsn
45:12 <K> cheaper
45:24 <K> lcd is old as dirt
45:39 <hsn> hmm,, so TFT, oled ?
46:17 <K> um, i assume that by 16x2 you mean those green/bluish dot matrix types
46:32 <K> i would say those are more rugged than any eink or oled ones
46:35 <hsn> yes Liquid crystal ^
47:03 <hsn> tft is worse than oled right?
47:07 <K> although neither will survive if hit with a brick
47:18 <hsn> lol
47:30 <K> tft needs more power afaik
47:45 <K> and backlight still, oled does not need backlight
47:53 <K> as it is, well, led
47:55 <T3sl41> i don't know that any of them have particular life problems, aside from OLED which is always improving
48:15 <K> temp ranges might come in play
48:16 <T3sl41> a bit confused by that one saying "transflective" but it has a backlight
48:18 <T3sl41> maybe it's both
51:31 <hsn> T3sl41 hmm, but wouldnt it be more easy to make (single backlight) last more and lots of small size ? im just thinking ?
51:42 <hsn> more than lots **
52:10 <T3sl41> conversely, what if the backlight fails, versus one or a few OLED pixels?
52:19 <T3sl41> AFAIK, the failure mode isn't single failure anyway
52:24 <hsn> right
52:44 <hsn> my bmw has line of pixels failed
52:49 <hsn> in the obd
52:59 <hsn> vertical
56:51 <T3sl41> wonder if it's not COG
57:31 <T3sl41> row/col failures are typical of mech failures of flex connections, where the drivers are on a PCB
58:14 <coppice_> Chipped Off Glass
02:40 <coppice_> hsn: is the line of dead pixels in the most prominent part of the screen?
02:40 <hsn> i think its COG but im not sure .. https://snipboard.io/tC5v86.jpg <------ this is cog right ??
03:05 <hsn> coppice_ one day its there .. next day its not there xD ..
03:45 <T3sl41> probably not, it's got contacts the whole way across the edge?
04:00 <coppice_> hsn: does it come and go with temperature? that's quite ommon
04:41 <hsn> i think,, but not sure .. i mean we dont have (sever cold) here !! 10 is pretty minimum it can get ..
04:46 <hsn> 50 is maximum at summer
05:00 <hsn> C
05:04 <hsn> celsius
05:30 <hsn> https://youtu.be/xyxUtz8kvLU?t=313 <--- the cat loves 3 phase power analyzer
06:17 <coppice_> I was thinking more of self warming. We had a TV with a vertical line problem, but only for the first few minutes. Self heating seemed to reliably seal up the problem
06:55 <coppice_> hsn: That's a classic Voltech product - designed never to be taken apart
07:14 <hsn> it has a problem thats why he open it
07:53 <coppice_> yeah, and it was ridiculously difficult. every Voltech product is like that
08:26 <coppice_> anything you want to do requires a total teardown
08:55 <coppice_> I wonder if they are still like that now they are part of Tektronix?
11:34 <hsn> i've no experience in this i just enjoy watching with believe that i will catch some knowledge from here and there ...

58:58 <Ysjoelfir> Hi rusty
59:10 <Ysjoelfir> hi hsn
59:31 <hsn> how is meeting
59:43 <rust_collector> poopcorn
00:21 <hsn> rusty ^ if you talk about this T3sl4 might jump with few pictures .. carefull xD
00:52 <rust_collector> Yes, he hacked my server, so he does have a lot of my pics
02:52 <rust_collector> I am officially outside, fixing my car
04:08 <rust_collector> 18 years of salt and crap if probably better than using bolts
04:49 <rust_collector> think of all the bolts they could skip installing, if they just used a bit of time, to let things rust solid
05:52 <rust_collector> I guess you could use non threaded bolts, just whack them in with a hammer, you could hire carpenters to assemble your cars
06:06 <hsn> so its (rusty) bolts
07:02 <hsn> non threaded bolts -> nails ?
07:05 <rust_collector> yes
07:08 <Ysjoelfir> meeting was great. We now decided what to do when corona strikes
07:23 <Ysjoelfir> which basically means, I get a free laptop
07:29 <rust_collector> go on vacation?
07:35 <rust_collector> workation?
07:37 <Ysjoelfir> more or less that, yes
07:54 <hsn> boss fight corona with laptops to employees
07:56 <hsn> ?
08:00 <Ysjoelfir> exactly
08:12 <Ysjoelfir> ok, combined with the closing of the facility
08:17 <Ysjoelfir> so we could work from home
08:33 <Ampera> blech, at work now
08:35 <Ysjoelfir> at least we engineers. the production facility will be closed
08:39 <Ampera> my computer for some reason got shut off
08:43 <Ysjoelfir> have fun ampera :)
08:47 <Ysjoelfir> thats always nice
09:22 <rust_collector> how much stuff do you people produce in say a week? I sort of think you do not do huge volumes?
10:00 <hsn> eevblog status
10:01 <EEVBlog> Latest EEVBlog Tweet: Another cruise ship isolated! https://t.co/OWNSmnu2cg That might be the death blow for the cruise ship industry. But I guess never underestimate the allure of a bargain...
10:12 <hsn> Ampera, for me its live
10:58 <Ysjoelfir> you are right rusty. we produce.... lets say... 10 devices a week?
11:26 <rust_collector> hmm, how many people work in production?
11:42 <Ysjoelfir> around 20
11:46 <Ysjoelfir> 10 in sales and management
11:51 <rust_collector> hehe
11:53 <Ysjoelfir> and 25 in engineering
12:04 <Ampera> looks like a power cut
12:35 <Ysjoelfir> however, I'm home for now :)
12:42 <rust_collector> yaay?
12:44 <Ysjoelfir> I guess we will read again later. bye :)

12:58 <rust_collector> uhm, ok
13:22 <hsn> guys shouldnt this status be like what i put the arrow https://snipboard.io/IYyEul.jpg ?
14:47 <rust_collector> errfff, I think they just have some pics up top there. ther do not seem to actually mean anything
14:55 <rust_collector> keeps people happy
16:23 <hsn> they get colored
17:16 <hsn> https://snipboard.io/Xireo4.jpg
17:46 <hsn> probably they didnt parse it correctly to update the status of pictures
22:09 <coppice_> Ah, the joys of living in the countryside. Looks like we have more mice
23:01 <hsn> fck i cant handle (not peeing) like i used to when i was kid
24:43 <coppice_> hsn: you mean the local swimming pool is no longer accepting of you relieving yourself from the top diving board?
27:02 <hsn> i dont pee a lot .. but when i need too .. i cant wait
28:31 <hsn> coppice_ but im free heater ..
28:36 <hsn> :)
28:54 <hsn> less power for them
57:12 <Ampera> of all that can be said for working here, I have the best coworker, he give me jerky

53:42 <rust_collector> that is not new, it has been around for around 30 years now
02:39 <Ysjoelfir> well... pretty exactly 30 years now^^
02:55 <Ampera> Blech
02:59 <Ampera> Existence
03:02 <Ampera> Blech
03:23 <Ysjoelfir> nobody likes existances!
07:15 <Ampera> I've gone for a walk
07:34 <Ysjoelfir> nice :) I hope you enjoyed it?
07:37 <Ampera> It's a chilly 44 out
07:45 <Ampera> No I'm walking right now
07:46 <Ysjoelfir> that sounds pretty hot to me
08:11 <Ampera> I should have the EEVBot do conversions
08:18 <Ysjoelfir> hm?
08:24 <Ysjoelfir> oh, °F
08:30 <Ampera> Yee
08:42 <Ysjoelfir> well, 6.66666666666666666666666666666666666666°C
08:57 <Ampera> As i said, cold as hell
09:01 <Ysjoelfir> that sounds like a temperature I personally would enjoy :)
09:11 <Ysjoelfir> I don't like it to warm
09:22 <Ampera> It's alright
09:40 <Ampera> I prefer between 50 and 60 with little wind
10:31 * Ampera licks T3sl4
11:30 <Ysjoelfir> that would be 10 to 15°C. Sounds pretty great to me
11:38 <Ampera> Aye
11:57 <Ampera> We're almost done with regression at work
12:24 <Ampera> Well, pretty much done, there's always tests that straggle
12:49 <Ysjoelfir> hehe
13:14 <Ampera> It still blows my mind i can be outside in the woods and use IRC
13:26 <coppice_> I'm done with regression. I promise not to cause any more of it
13:32 <Ysjoelfir> I'm pretty happy to be home for today. this day was so packed with corona panic that I nearly freaked out because of all this stupidity
13:50 <Ysjoelfir> It sounds pretty usefull ampera :)
14:20 <Ampera> Consumer essentials markets just be through the roof
15:16 <coppice_> rice, rice, baby
15:30 <Ysjoelfir> I had to fight someone for a bottle of oil...
15:44 <Ampera> Did you win?
15:44 <Ysjoelfir> she wanted to take THREE whole shipping boxes full of oil
15:45 <coppice_> baby oil?
16:01 <Ysjoelfir> I wanted one damn bottle.
16:06 <Ysjoelfir> no, sunflower seed oil
16:12 <Ysjoelfir> and yes, I won
16:21 <Ysjoelfir> well
16:26 <Ampera> Well that's all that matters in a fight
16:39 <Ysjoelfir> I just took one from his cart while he tried to carry the third box
17:10 <Ampera> Stealth is as good of a tactic as any
17:15 <Ysjoelfir> "how dare you, I must be prepared for corona, you just stole that from me!!!"
17:27 <Ysjoelfir> well... technically I did not steal it
17:35 <Ysjoelfir> since it wasn't his^^
17:50 <Ampera> Not sure what a bottle of will do against a virus
18:00 <Ysjoelfir> hers
18:00 <Lemonizer> https://img7.leboncoin.fr/ad-large/4ce7c7956ab945cb326afa3e9b6303eeb977590d.jpg can someone tell me the probe/connector needed for the top left input please ? its a conductimeter
18:06 <Ampera> Nor three crates of it
18:10 <Ysjoelfir> was a woman. not a man
18:15 <Ysjoelfir> indeed
18:39 <Ysjoelfir> as I said Lemonizer, I assume it is a Tuchelstecker
19:08 <Ysjoelfir> the old variety
19:38 <Lemonizer> hmmmm well I said top left but wait
19:40 <Lemonizer> its an input
19:47 <Lemonizer> ha yeah
20:02 <Ysjoelfir> yes, I meant that top left one. the "entree"
20:05 <Lemonizer> I can have the same model but in grey for 15 euros with shipping
20:16 <Lemonizer> dude told me the galvanometer is fine
25:24 <Lemonizer> also I saw dis https://www.ebay.fr/itm/PHILIPS-pm-5705-pulse-generator-0-1-Hz-10-MHz-FREE-P-P-UK/283371093207?hash=item41fa3bbcd7:g:rxsAAOSwQmJcXb-0
26:05 <Lemonizer> theres the 50mhz version a tad more expensive https://www.ebay.fr/itm/Philips-PM5712-Pulse-Generator-1Hz-50MHz-Rise-time-4ns/254491404052?hash=item3b40dea714:g:3pwAAOSwNQReJuHs
28:31 <Lemonizer> 4ns of risetime seems fast !
28:42 <Ysjoelfir> 50 millihertz or not - it's from philips, so it's bad.
28:50 <Lemonizer> MHZ YES
28:55 <Lemonizer> why that ? :>
28:57 <Ysjoelfir> (well, not realy, but I don't like philips at all)
28:59 <Lemonizer> they made nice things !
29:22 <coppice_> Philips used to make some great instruments
29:31 <Ysjoelfir> they did indeed.
29:36 <coppice_> and not just by a fluke
29:53 <Lemonizer> idk if the 10mhz version is enough for some tinkering
29:56 <Ysjoelfir> I just don't like them at all
30:44 <Lemonizer> https://www.ebay.fr/itm/EMG-100-MHz-Pulse-Generator-Type-TR-0307-Amateurfunk-Ham-Radio/223501638669?_trkparms=aid%3D1110001%26algo%3DSPLICE.SIM%26ao%3D1%26asc%3D20131003132420%26meid%3Df4cff609d62443349ea57167908e5b82%26pid%3D100005%26rk%3D7%26rkt%3D12%26mehot%3Dpf%26sd%3D254491404052%26itm%3D223501638669%26pmt%3D0%26noa%3D1%26pg%3D2047675&_trksid=p2047675.c100005.m1851
30:51 <Lemonizer> google translate doesnt work, for some reasons
30:57 <Lemonizer> can you tell me which defect it got please ?
31:21 <Ysjoelfir> hrm
31:30 * Ysjoelfir clears his throat
31:40 <Lemonizer> :>
31:42 <Ysjoelfir> We sell that device as defective, because:
31:44 <Lemonizer> its a nice piece of kit
31:49 <Ysjoelfir> - we have no clue about it
32:08 <Ysjoelfir> - a big cap in the power supply broke off (you can see it if you look through the vents)
32:15 <Ysjoelfir> - the device is old
32:45 <Lemonizer> interesting
32:52 <Ysjoelfir> Cosmetic aspects: The device is dusty but it can be cleaned. On the hood are some scratches and minor dents (was mounted in a rack)
33:15 <Lemonizer> yeah nothing
33:19 <Lemonizer> if its just a cap, well
33:23 <Lemonizer> but thats hard to say
33:49 <Ysjoelfir> I didn't look for scratches, dents, dirt and surface rust, stuff like that would be possible. Please take a look at the pictures. They show the device that you will receive

34:02 <Lemonizer> thanks buddy
34:05 <Lemonizer> we got the important infos
34:14 <Ysjoelfir> ok :)
34:20 <Lemonizer> whatcha think ?
34:27 <Lemonizer> a 100mhz pulse gen like this is really interesting
34:30 <Lemonizer> for that price
34:31 <Ysjoelfir> but I wanted to translate all those nice disclaimer sentences!
34:33 <Lemonizer> if its no big deal
34:39 <Lemonizer> haha !
34:50 <Lemonizer> 'we dont accept returns, you buy what you see'
35:06 <Ysjoelfir> oh, and also: it is stored on the yellow shelve!
35:16 <Lemonizer> ha good, good
36:28 <Lemonizer> idk if those things are fixable easily
37:23 <Ysjoelfir> well... I usually go for the following principle: if it's over a few hundred kilohertzes it is potentially unfixable if you aren't an RF magician^^
37:44 <Lemonizer> hmmm I see
37:48 <Ysjoelfir> but thats just because I don't like working with high frequencies
38:03 <Ysjoelfir> someone familiar with that will most probably tell you that it's easy
38:05 <Lemonizer> I need to focus on the clock !
38:17 <Ysjoelfir> it's 18:38

46:10 <Lemonizer> thats why hate those things :>
46:35 <Ysjoelfir> sometimes that smart thing is just not very smart but instead very annoying
47:05 <Lemonizer> also you know about pulse generator, or other things with bandwith, I always get a hard time deciding which bw I'll need
47:13 <Lemonizer> as I'm using those things to experiment, learn things
47:33 <Lemonizer> will the 10mhz be more than enough ? 50mhz too much ? the opposite ? well
47:48 <Lemonizer> I know pulse gen are nice for stimulus of digital thingies
48:13 <Ysjoelfir> we have a ceiling fan in the living room. once that damn alexa thing decided that it doesn't understand me anymore. "echo, switch on the ceiling fan!" - "I'm sorry, there is no device such as "sailing flame!""
48:21 <Ysjoelfir> that went on for a week
48:30 <Lemonizer> nice xd
48:31 <Ysjoelfir> so I renamed that thing to sailing flame
48:38 <Lemonizer> Id throw it through the window
48:48 <Ysjoelfir> now if I want it to switch the fan on I ask it to switch on the sailing flame
49:15 <Ysjoelfir> last week all of the sudden it decided that it doesn't know what that is anymore

07:20 <hsn> pulse generator u mean these ones who use transistor avalanche break with fast rise time ?
08:51 <Lemonizer> those who ouputs a square signal where you can control delay, width etc
10:07 <hsn> for what use?
10:21 <Lemonizer> experimentation ! :P
10:54 <hsn> wouldnt signal generator do ?
11:12 <Lemonizer> well not exactly, as it ouputs a continuous square wave
11:20 <Lemonizer> and you dont have the same controls over it
11:50 <hsn> right
12:07 <Lemonizer> im all about getting new test gear to learn and play with it :>
12:49 <Lemonizer> I have a wavetek 164 as a function gen, and two other small 2Mhz ones that I dont use

45:02 <rust_collector> oh, 41, lol
45:29 <hsn_> nice, u work or ur own business?
46:09 <hsn_> Ysjoelfir, u do color each user text on (adilIRC) ?
46:13 <Ysjoelfir> yes, hsn?
46:16 <Ysjoelfir> yes I do
46:21 <hsn_> where to do it
46:22 <rust_collector> i am employed by a company. nothing related to this kind of stuff
46:26 <Ysjoelfir> you are right now a nice pink
46:32 <Ysjoelfir> rusty is rust-orange
46:40 <Ysjoelfir> lemon is yellow
46:45 <hsn_> this thing has huge option menu
46:58 <Ysjoelfir> halcyon is babyblue^^

47:11 <Ysjoelfir> it is pretty nice actually
47:17 <hsn> found it
47:23 <hsn> i guess
47:27 <hsn> ur yellow
47:53 <Ysjoelfir> nice, i love yellow!
48:03 <hsn> just like ur logo
48:13 <Ysjoelfir> oh you noticed :D
48:21 <hsn> ur text is white ?
49:04 <hsn> somthing is not right https://snipboard.io/H9d3RD.jpg
49:06 <Ysjoelfir> my text is nick-colored
49:29 <Ysjoelfir> wait. lemme suggest some things
49:55 <Ysjoelfir> colors - both checkboxes on
50:02 <hsn> file > themese ?
50:13 <Ysjoelfir> no, tools - options
50:30 <hsn> ok colors - both check box [x]
51:07 <Ysjoelfir> highlights - I have the first four active, the others as standard
51:31 <hsn> so (flash text)
52:06 <hsn> https://snipboard.io/7KZQpX.jpg
52:11 <Ysjoelfir> yes. I think thats the only one that i activated additionally. inline images: use inline and use gifs. filesize: 2048kb, cach: 100mb
52:19 <Ysjoelfir> yes
52:37 <hsn> for colors (it didnt change as my theme override it ) which theme u choose?
53:01 <Ysjoelfir> one sec
53:52 <Ysjoelfir> messages: use timestamp, highlight matching, use unread line marker, show empty line at bottom, ignore nick for consecutive
54:42 <Ysjoelfir> nick colors: use random and use extended (those are important, otherwise it won't override the theme colors!)
55:12 <Ysjoelfir> and also: tick "enable nick, color lines and color nicks
55:44 <hsn> right
56:16 <Ysjoelfir> and for the theme: I use the "classy theme"
57:17 <hsn> https://snipboard.io/tZxL9J.jpg
57:24 <Ysjoelfir> I would also suggest that you add in server - server list - commands: add the /msg nickserv identify *yourpassword*
57:58 <Ysjoelfir> that is strange. for me it looks like that:
58:23 <Ysjoelfir> https://snipboard.io/hnze5T.jpg
58:40 <hsn> isnt it same as https://snipboard.io/zgbuxk.jpg << password ?
58:56 <Ysjoelfir> no.
59:15 <Ysjoelfir> Thats because austnet isn't modern enough to use those auth methods

02:52 <hsn> thanks
04:32 <Ysjoelfir> does it work now? :)
05:01 <hsn> well .. my room has bad lighting so i dont think anything will work
05:06 <hsn> but its much better
08:37 <Lemonizer> that pisses me off for the systron donner, I really want it adjusted/calibrated
12:01 <hsn> i cant wait for this .. https://snipboard.io/2rQNaR.jpg
13:57 <Lemonizer> if I can find the schematics, I could see if any resistors in the ratio divider drifted
13:59 <Lemonizer> maybe its the case
14:06 <Lemonizer> as its only on the 10v range

40:51 <Lemonizer> if I test resistors with the lcr meter without desoldering them, I can still get a rough idea right ?
40:55 <Lemonizer> if they drifted or not
41:05 <Lemonizer> I know theres the circuit impedance that plays but well
41:09 <Lemonizer> shouldnt be too much no ?
43:57 <Ampera> only about an hour left of work
44:09 <Ampera> then I get paid tomorrow and only have to work one more day until the weekend
44:12 <Ampera> :)
46:00 <Ysjoelfir> no. you can't. well, not always at least.
46:12 <Ysjoelfir> immagine a cap sitting in parallel to the R.
46:24 <Lemonizer> but as long as theres not, its fine no ?
46:28 <Ysjoelfir> you will have different readings in dependence of the test frequency
46:33 <Lemonizer> I mean, a resistor divider network should be fine
46:58 <Ysjoelfir> no. if there is a semiconductor in parallel you may get a vastly wrong reading
47:01 <Lemonizer> because that would suck if I have to delsoder them :/
47:03 <Ysjoelfir> or a coil
47:33 <Ysjoelfir> dividers are usually ok, IF the loop isn't closed at any point - it's good since you are then indeed reading only one res at one time
47:40 <Lemonizer> but if theres nothing in parralel
47:44 <Lemonizer> thats fine right ?
48:09 <Lemonizer> I will see, as I Dont have the schematics anyway
48:18 <Lemonizer> but as its only on the 10v range hopefully theres no many resistors
48:23 <Lemonizer> idk why but im sure its that problem
48:28 <Lemonizer> just a drifted resistor
48:42 <Lemonizer> maybe it got overloaded or something
48:59 <Ysjoelfir> could be
50:14 <Lemonizer> I'll be really happy to fix it, its nice and the display is perfect !
50:46 <Lemonizer> also I keep thinking of what to get once my laptop/desktop is sold, instead of random shit or collectibles I want to grab some stuff that I will use and keep a long time
51:01 <Lemonizer> it will probably be a nice DSO, like a tek tds 540 or something like this
51:07 <Lemonizer> if I can find decent probes for not too much
51:22 <Lemonizer> along with other things that I dont know yet, might be components and stuff to learn :>
15:17 <Lemonizer> those Ifixit screwdriver kits are really a nice investment
15:23 <Lemonizer> 60 euros for both, small and bigger bits
15:30 <Lemonizer> works well, solid, lots of tips
15:48 <Lemonizer> I just openned my tek 2245 to remove the handle, to save some space on the desk
15:58 <Lemonizer> it was using security torx
16:02 <Lemonizer> and needed some torque
16:10 <Lemonizer> np for them drivers
16:16 <Lemonizer> considering the price, its really unbeatable
16:27 <Lemonizer> also when I openned it I found a brand new mini wima blue cap xD

22:35 <Ampera> what makes you think that
22:38 <Ampera> I could still be outside if I wanted
22:42 <Halcyon> Because you were driving before
22:52 <Ampera> why couldn't I still be
22:56 <Ampera> or rather my dad was driving I was in the car
23:15 <Halcyon> Ah right, I was wondering how you were responding to my messages if you were driving :P
24:21 * Ampera throws a dollar coin at Halcyon 
24:24 <Halcyon> Oww
24:28 <Ampera> I've learned that the vending machine at my work gives them as change
24:31 <Ampera> which is crazy
24:36 <Halcyon> Why is that crazy?
24:45 <Halcyon> (Not that I use a lot of vending machines)
24:56 <Ampera> because dollar coins are exceptionally uncommon here
25:06 <Halcyon> Oh right because you have the notes
25:13 <Halcyon> Sorry "bills"
25:15 <Ampera> aye
25:20 <Ampera> they're notes and bills
25:25 <Ampera> we call them both
25:29 <Halcyon> Weirdo
25:40 <Ampera> at least we don't call them dollarydoos
25:43 <Halcyon> But yeh, why would you have coins and notes for the same denomination?
25:58 <Halcyon> We don't either. Hahaha. You've been watching too much of The Simpsons
26:23 <Ampera> well we do
26:27 <Ampera> they still mint them
26:37 <Ampera> our denominations are as follow:
26:43 <steve30> They still have pound notes in the channel islands. I /think/ they have their own pound coins as well, but the notes are more common. Although they are used alongside English coins too.
26:58 <Ampera> .01 .05 .10 .25 .50 1$ for coins (with exceptions)
27:15 <Ampera> 1$ 2$ 5$ 10$ 20$ 50$ 100$ for standard notes
27:32 <Ampera> 500$ 1000$ 10000$ 50000$ 1000000$ for reserve/special notes
27:47 <Halcyon> We need to get rid of our 5 and 10 cent coins, they are almost useless these days.
27:54 <Ampera> we also never technically retire currency from service, so all US currency ever minted is valid to this day
28:03 <Halcyon> Yeh same here
28:20 <Halcyon> We got rid of 1 and 2 cent coins in the early 1990's but they are still legal tender
28:25 <Halcyon> As are past notes/coins
28:45 <Ampera> we used to have half cent coins actually
29:07 <steve30> I deposited a load of old style £1 coins in the bank the other week. Technically they are worthless, so I'm surprised banks still take them.
29:19 <Halcyon> That being said, you can't just roll up somewhere with a wheelbarrow full of coins, that is no longer legal tender and can be refused
29:36 <Ampera> it is here in theory
30:31 <coppice_> steve30: isn't there a very long term requirement for banks to exchange old currency?
31:09 <steve30> Not that I'm aware of. The Bank of England exchanges old bank notes, but that's about it.
31:14 <Halcyon> Anyway, I'm going to go poop, then head to the post office again to post your package Ampera
31:21 <Ampera> alright, thanks
31:30 <Ampera> I'm going to scavenge for food

54:23 * T3sl4 shrug
54:31 <hsn> is this what determines input impedance : https://snipboard.io/mY2GU8.jpg ?
55:03 <hsn> im just thinking of Q1 as R and C
55:48 <T3sl4> yes, Q1 has some input admittance which acts in parallel with R2, and those in series with R1
56:22 <hsn> so selecting Q1 is so critical and specific in this type of designs
56:37 <T3sl4> that admittance being largely capacitive
56:48 <T3sl4> well, sort of
57:11 <hsn> and requires tuning .. and hope that manufacturer will not change any thing in next patches
57:13 <hsn> ?
57:27 <T3sl4> i guess the worst case JFET you can buy is either J105 if it's not discontinued yet, or a SiC or GaN something or other
58:38 <T3sl4> any reasonable JFET (Idss ~ 0.2-50mA say) will have probably 2-40pF Ciss, not really insane at these frequencies
59:28 <hsn> if it was 10Mhz design .. would it work ?
59:56 <hsn> with less impedance input ?
00:11 <hsn> btw im just scratching around no idea how this thing works ! :)
00:44 <T3sl4> work for what? my scope says 1M || 15pF and is rated 350MHz BW
01:32 <hsn> work as amplifer dB21
01:46 <T3sl4> for an unspecified source?
02:46 <hsn> well this raise a question
03:28 <hsn> ur scope probe has 10x gain .. very large DC offset .. 0-350MHz ?
03:56 <T3sl4> er... 10x attenuation
03:58 <T3sl4> DC offset where?
04:17 <hsn> i mean it works on dc biased signal
04:32 <T3sl4> yes, it's DC coupled
05:27 <hsn> but this one in the question cant work on ( > 0.2v dc) right ?
05:53 <hsn> Input level: 200mV rms
07:54 <T3sl4> probably not much more than that, i mean 11x gain is 2.2V out and it's only +/-5V supplies with no particular attention towards rail to rail capability
09:15 <T3sl4> you can run it up to about 6V input before running into (much) gate current, and the input series 1k will limit that safely for up to +16V or so, i suppose
09:34 <T3sl4> obviously the output is just saturated to whatever, for such inputs

23:29 <Halcyon> Howdy
24:18 <lbrywatcher> is dave jones also active now in this chat. i have found a problem with eevblog.tv of linking to lbry.tv
24:40 <Halcyon> No he isn't, but what's the issue?
24:51 <Halcyon> I can send it through to the sysadmin
25:36 <lbrywatcher> @Halcyon how do i that?
25:49 <Halcyon> Tell me what the problem is and I'll send them an email
29:23 <lbrywatcher> if i go to eevblog.tv i get first a message (in firefox for windows) that the https cerfificate is not working good. and then as i click trough i get (somtimes now it is working but i have lbry open at this moment) a weird site to see. i am not linking to lbry.tv
29:45 <Halcyon> Sounds like an issue with your machine, not the site
29:58 <Halcyon> If I had to guess, perhaps malware on your PC?
30:03 <lbrywatcher> @Halcyon i use different addons in that browser
30:21 <lbrywatcher> i will scan for virus now
30:25 <Halcyon> I just tested the site now and it redirects just fine
30:29 <Halcyon> No certificate errors
30:44 <Halcyon> I would say that something on your machine is trying to redirect somewhere where it shouldn't and the certs don't match
30:53 <lbrywatcher> i will test i now after a browser restart
31:33 <lbrywatcher> @Halcyon, yeh now it is working
31:56 <Halcyon> Awesome
32:54 <lbrywatcher> now i have clicked the wrong firefox install now is it not working in the orher firefox install
35:35 <lbrywatcher> i can send a screenshot of the problem.
36:15 <Halcyon> Yep, post it to imgur.com
36:40 <lbrywatcher> is a onedrive public download also good?
38:46 <Halcyon> Sure
39:44 <lbrywatcher> i have set my firefox language to englesh us and now it works. strangs

45:37 <Halcyon> Well I'd sggest you found your problem
45:50 <Halcyon> Also, I can't read Dutch so that screen shot is meaningless to me
46:19 <lbrywatcher> i will search for you for the engels versie.
46:27 <lbrywatcher> give my a second
46:33 <Halcyon> I think you answered your own question
46:52 <Halcyon> It's obviously a language issue with Firefox and for some reason it's upsetting the certificates
50:26 <lbrywatcher> here is the English version of the error English
50:39 <lbrywatcher> https://1.bp.blogspot.com/-rJANGuSjumo/XRsN0NF-flI/AAAAAAAA0TY/7yIYPtNG5kUoMmfpwap2wrOpJyUK-eShwCLcBGAs/s728-e100/firefox-https-error.jpg
51:58 <lbrywatcher> as it is only wen the language then it is what you say a bug in firefox

09:08 <lbrywatcher> @Ysjoelfir, i came here now en than on a thifferent username the last couple of weeks fior what questions.
09:25 <Ysjoelfir> ah :)
10:19 <lbrywatcher> @Ysjoelifr, i ben here now for report a bug with the eevblog.tv site. @Halcyon is helping my with contact to the sysadmin
10:39 <lbrywatcher> it is a strang bug in the https certifcate
11:51 <Ysjoelfir> ok. I have no idea about software stuff, so.... yeah :D
11:58 <Ysjoelfir> you will be doing the right thing, I'm sure
13:14 <lbrywatcher> @Ysjoelfir, it is a very strange bug and i'm not sure if it is the cerifate or a bug in the browser
15:44 <Ysjoelfir> I'm sure it will be on of those.
17:58 <lbrywatcher> yes i think also. i have read this week in the news that there is a bug with some certifcates. but i think not that this is related to this.
18:51 <lbrywatcher> @Halcyon, @Ysjoelfir, than it is fix by request a now certificate

09:08 <Halcyon> Haven't emailed him yet, still waiting on the issue
09:14 <Halcyon> If the problem is with the LBRY cert
09:29 <Halcyon> That's not an EEVblog problem

12:42 <Lemon> hi :>
15:23 <Ysjoelfir> Finally my Bachelors grade found it's way from the desk of the two antigraces in the examination office to my online summary of performance

17:14 <lbrywatcher> @halcyon, i have send the screenshot of the problem or may you the problem on your side?
19:50 <Halcyon> Yeh your screenshot shows example.com
19:55 <Halcyon> I don't see how this is related?
20:50 <Halcyon> The eevblog.tv website redirects to LBRY, so it would be LBRY's certificate (if it indeed is a problem at all). However it looks like you are the only one having issues. I would suggest there is something either wrong or misconfigured at your end.
21:48 <Halcyon> This OWASP Zed Attack Proxy looks suspicious to me. It looks like it's trying to intercept websites and doing a bad job at it (or it's malware).
22:38 <Halcyon> There is not much I, nor Dave can do about it unfortunately as it's not an issue with the site.
22:52 <lbrywatcher> https://1.bp.blogspot.com/-rJANGuSjumo/XRsN0NF-flI/AAAAAAAA0TY/7yIYPtNG5kUoMmfpwap2wrOpJyUK-eShwCLcBGAs/s728-e100/firefox-https-error.jpg this is a public image i have found on the web for the English it say so that it is clear with eror i get. and it is a independ error on with site you visit with this problem
23:03 <Halcyon> Yes, I saw it
23:44 <Halcyon> From what I can see, there is no problems with the certificate on LBRYs site
23:54 <Ysjoelfir> lbry works just fine
24:11 <Ysjoelfir> https://security.stackexchange.com/questions/147250/why-are-https-requests-blocked-by-firefox-when-using-zap-proxy
24:23 <Halcyon> Why are you using ZAP proxy ?
24:28 <Halcyon> It seems to be broken
24:33 <Ysjoelfir> one second of googling that strange proxy thing.
24:34 <Ysjoelfir> ZAP creates certificates, on the fly, in the name of the site Firefox is going to.
24:34 <Ysjoelfir> Firefox is saying "I don't trust the CA that signed this cert", which is reasonable, because it's a MITM by an unapproved certificate authority.
24:34 <Ysjoelfir> You need to import Zap's signing certificate into Firefox's Trusted Roots Certificate Store. If you Google "zap install certificate" you get lots of links to do so:
24:49 <Halcyon> Yes, so it's something you have installed on your machine
24:52 <Halcyon> Not a problem with the server
25:09 <hsn> aah
25:18 <hsn> root ca to be added to firefox?
25:31 <lbrywatcher> ok. then it is just a problem by me. but i hope that is is not for other people. and i have commit thsi problem so that it is now in the communty.
25:48 <lbrywatcher> thanks everybody for hanging out
25:53 <Halcyon> As I said, you are the only one having this issue it seems.
26:28 <hsn> there is news about (let't encrypt)
26:47 <hsn> as there is vulneribility in their auto cert. issue process i guess
26:56 <Ysjoelfir> whatever that is :D

50:20 <Ysjoelfir> you mean ebay.fr/114004687270 ?
50:23 <Lemon> why ts so long
50:39 <Lemon> the symmetricom gpsdo 10mhz 1pps one
50:43 <Lemon> 89 usd
50:45 <Ysjoelfir> because u schtuppit :P or because you just copied the link without checking^^
51:23 <Lemon> shipping is long but well
51:30 <Lemon> symmetricom is a nice brand if im right
52:15 <Ysjoelfir> no idea, that's to fast for me :D
52:28 <Lemon> 1pps is 1hz ! :P
52:55 <Ysjoelfir> but 10 notmillihertz is rather fast^^
53:09 <Lemon> stop itttttt
53:13 <Lemon> you get the ideaaaaa !
53:19 <Lemon> its the morninggggg
57:35 <Lemon> ok so lemme see if have I shift registers
57:38 <Lemon> thats a possibility
57:50 <Lemon> but I dont know common references
09:25 <Ysjoelfir> 74xxx595 is the one I use most often.
10:17 <Ysjoelfir> other ones are.... I think 74164 and 74299 are ones I have had in my pile of junk once
21:31 <Lemon> ok thanks im going to search for them
21:33 <Lemon> theres so much
21:41 <Lemon> I kinda sorted them but well

38:37 <Ysjoelfir> yay :}
44:24 <Lemon> HA !
44:39 <Ysjoelfir> Lemon!
44:44 <Lemon> 74HC595N
44:58 <Lemon> tell me those are fine please !
45:15 <Ysjoelfir> My 3456A just drifted around 1µV when you wrote! don't do that ever again!
45:24 <Ysjoelfir> yeah they are fine :)
45:26 <Lemon> damn sorry boi
45:28 <Lemon> haaaaaa yessssssss
45:39 <Lemon> I got 23 !
45:43 <Lemon> thanks daddddd
46:00 <Ysjoelfir> nice :)
46:05 <Ysjoelfir> They are pretty easy to use
46:16 <Ysjoelfir> just shove the data in, toggle the latch and off you go
46:50 <Lemon> so with those, and a random arduino, I'll be able to pilot 17 displays ?
46:56 <Lemon> that will be fine ?
47:29 <Ysjoelfir> that depends on your displays, but you can command one display with way less lines than you would normally
50:29 <Lemon> honestly the only times I used those displays was with an arduino micro, just to light each segment for fun :>

20:23 <Lemon> ho I thought about something
20:26 <Lemon> I might not have enough resistors

37:38 <DaveO> Hi, I'm after a recommendation for a half decent DMM supporting capacitor testing - and general all-rounder.
39:59 <K> testing for what?
40:01 <K> capacity?
40:19 <DaveO> I should have added - a DMM recomendation at a decent price. I have an Aldi DMM which for the price has been pretty good, though time to get something better. I have an old oscilloscope
40:22 <K> esr? esl?
40:47 <Lemon> what is a decent price for you ? :)
40:56 <DaveO> Ahh - actually I found your video - when checking known faults to fix a Yamaha RX-V2067
41:06 <DaveO> .. I'm sydney based..
41:34 <DaveO> If it's good - I could pay up to $300.. I don't use them enough to spend more.
42:05 <Lemon> second hand is an option ?
42:19 <DaveO> Was looking to buy a decent fluke 'electricians' true RMS meter a while ago - but it didn't happen ..
42:22 <Lemon> I think new you could get one of those brymen, 879s or something, I might get the number wrong
42:36 <Lemon> or a second hand fluke + a lcr meter like the xjw01
42:38 <DaveO> Yes, if in good condition , and a decent meter, I don't mind second hand.
42:52 <DaveO> As long as it doesn't have any issues or not accurate..
43:08 <Lemon> id grab a second hand bench dmm + a xjw01 :>
43:21 <Lemon> if you dont mind about space
43:35 <Lemon> a 3456a is an option at that price, the lcr meter is 60 euros
43:58 <DaveO> Okay, I'm not familiar with these, will look email.up..
44:05 <DaveO> Am I chatting to Dave?
44:14 <K> nope
45:12 <K> you can think about this channel as forum on crack
45:14 <Lemon> :>
45:26 <DaveO> Ahh :-)
45:46 <Lemon> im not on the forum, but Im there everyday
47:19 <K> still, if you hang around, someone might give you a recomendation on alleviating your plight.
48:56 <K> DaveO, fwiw, i bough a second hand fluke 187 on ebay, 190 pounds, iirc. am a happy camper
49:08 <Lemon> the hpo 3456a is a 6.5 digits bench dmm
49:21 <Lemon> you can find one for 200-250 with shipping being lucky
49:23 <Lemon> but theres other options
49:49 <Lemon> the xjw01 is a chinese lcr meter that works nice honestly, goes down to 0.1pf, 0.01pf maybe im not sure
49:58 <K> or a new brymen 8-hundred-something series would work as well
50:03 <Lemon> 0.1mOhms, and 100nH I think
50:16 <Lemon> yeah what I said earlier the 879s or something
50:23 <DaveO> Sure - thanks. I notice on one of the EEV YouTube videos diagnosing a Yamaha RXV receiver a DMM argument U1733C was used to do a capacitor test , notice this details online for ~ AUD730
50:55 <Lemon> that xjw01 is really more than enough :>
52:21 <Lemon> it even comes with decent kelvin clips
53:04 <K> that xjw01 looks nice indeed
53:15 <Lemon> I was really surprised for the price
53:40 <K> wonder how it compares to DE-5000
54:03 <Lemon> I think it gives a tad more infos/resolution, but im not sure
54:18 <Lemon> its a bit confusing but theres infos online

58:11 <DaveO> Okay - thanks for all your advice - I'll do some research. Cheers.
58:19 <Lemon> np !#
06:37 <Lemon> now the big question about my clock, is how many resistors of the same type I'll need
06:41 <Lemon> for 17 displays
06:46 <Lemon> I guess at least one for each
07:25 <Ampera> good morning
07:37 <Lemon> bonjour !
08:01 <Ampera> hey that's italian

13:25 <Lemon> so I have all the 7 seg display I need
13:31 <Lemon> 23 shift registers, should be enough
13:39 <Lemon> I have at least 20 resistors of the same type, should be fine
13:50 <Lemon> I miss a few red leds to make seperations between hours/minutes etc
13:55 <Lemon> but thats fine I'll find some
14:08 <Lemon> I have arduinos of all types, so no need to buy some special uC
14:23 <Lemon> now I need to find the core, an atomic gps reference :>
14:30 <Lemon> that sounds so cool !
15:29 <Lemon> and besides a clock I'll have a nice stable standard to calibrate stuff like my counter, maybe scopes etc
17:27 <K> the 7 seg displays non't have the dot segment?
17:38 <Lemon> yeah but I need double dots
17:40 <K> ah.
17:44 <Lemon> it looks better I think
18:02 <K> proly does yea
18:04 <Ampera> finances for this fortnight have been balanced
18:13 <Lemon> I'll use 9 large ones and 8 medium ones for year/months and days
18:28 <K> Ampera plays fortnite?
18:28 <Lemon> going down to millisecs is fine
18:30 <K> (booo)
18:37 <Ampera> K, no, I'd rather eat chalk
19:17 <K> is it that bad?
19:24 <Ampera> When I got my first paycheck I began a running tally of all my money, as well as subaccounts to keep track of where I was allocating funds within my checking account.
19:26 <Lemon> just snort it !
20:23 <K> yea, propper asbestos is probably hard to come by these days
21:18 <Lemon> I always wanted an atomic clock
21:53 Quit: Ysjoelfir ([email protected]) Quit: Farvel og har en hyggelige tid :)
21:54 <Lemon> I need a rubidium standard with a gps
24:06 <Lemon> I wonder how long rubidium last

37:38 <Lemon> im learning more things on atomic clocks !
38:02 <Lemon> and I had a question, wether its based on a quartz, rubidium or caesium cell, its still called an atomic clock right ?

42:01 Quit: DaveO ([email protected]) Quit: http://www.kiwiirc.com/ - A hand crafted IRC client
42:04 <Ampera> Lemon, I know nothing about atomic clocks, but I recall the concept being specifically related to detecting the gyrations of the outermost electron of a specific isotope of Caesium.
42:51 <Ysjoelfir> I could follow your explaination roughly to "I recall the concept"
42:56 <Ampera> I think /some/ of them might have sort of auxiliary timekeeping components like quartz oscillators, but those I believe are only used to aid in keeping track of the electron.
43:21 <Ampera> Ysjoelfir, so Caesium is an atom, and atoms have electrons, correct?
43:27 <Ysjoelfir> yes
43:46 <Ampera> and electrons form shells where the orbit around nuclei
43:51 <Ampera> *they
43:57 <Ysjoelfir> yes.
44:09 <Ampera> the outermost electron of a certain isotope of Caesium happens to move up and down a little bit at a very specific rate
44:27 <Ampera> as I understand it, atomic clocks are designed to measure that movement in order to keep time.
44:29 <Ysjoelfir> aaah, I think I see where this is going
45:00 <Ysjoelfir> ok. that sounds actually pretty "easy", in an "i understand the concept"-way
45:02 <Ampera> How exactly they do that might be where other elements like a quartz oscillator might come into play, but I've forgotten or never knew.
45:22 <Ampera> I don't even know if what I'm saying is right, I could be full of shit for all I'm sure of
45:39 <Ysjoelfir> it at least sounds pretty logic to me
45:59 <Lemon> quartz oscillators are used to count time, basically
46:02 <Lemon> from what I understand
46:07 <Lemon> but what you said is true yes
46:25 <Lemon> they use a quartz oscillators with a caesium source which does the magic
46:31 <Ampera> alright here's a slightly more specific explanation thanks to wikipedia, and what I remember from chemistry class :P
46:57 <Ampera> atoms release EMR when their electrons transition between energy levels
47:24 <Ampera> apparently Caesium-133 does this at a known rate, 9 192 631 770 times per second
47:48 <Ampera> this regular release of radiation can be measured and counted, presumably as Lemon said with a system based on a quartz oscillator.
49:52 <K> quartz oscilator prolly is involved in some control feedback loop
50:13 <Ampera> don't ask me to understand more, I'm impressed i was able to get that off the top of my head at all
50:49 <Lemon> so if I want to call it a proper atomic gps based clock, I need a caesium or rubidium source
50:59 <Lemon> or those hydrogen maser but we'll forget about those
51:35 <Ampera> As for rubidium, I wouldn't be surprised if one couldn't do it with most atoms which have constant electromagnetic decay, which ones those are I have no clue
51:58 <Ampera> maybe higher order alkali earth metals are special for that reason or something
52:31 <Lemon> https://www.ebay.fr/itm/1PC-EFRATOM-LPRO-101-10MHZ-rubidium-clock-Atomic-clock/163453847468?hash=item260e9bc7ac:g:9VsAAOSwhhlcJNhq
52:48 <K> there you go
52:48 <Lemon> so with one of those I need to turn the 10Mhz signal intot 1PPS
52:56 <Lemon> its a tad expensive
52:59 <Ampera> I wonder what sort of connection that is
53:14 <Ampera> ah, I should read
53:16 <Ampera> 10Mhz output
53:26 <Ampera> wonder if I could drive a CPU with that
53:48 <Ysjoelfir> that would be the most accurate cpu ever
54:47 <Ampera> would be the most retarded but also most awesome addition to a home 68k computer
56:16 <K> "didnt have any xtals at hand, eh"
57:19 <Lemon> the thing is
57:25 <Lemon> idk how long will last the rubidium
57:30 <Lemon> because I guess its not eternal
