18:15 * electrohead hugs Ampera
18:49 <Ampera> how are you doing electrohead
19:32 <electrohead> I'm alright, still waking up
19:37 <electrohead> you?
20:23 <Ampera> still in javascript hell
29:00 <electrohead> lol

37:55 <rust_collector> javascript... I was talking to one of the programmer guys at work, and they are moving to something more modern, because they can not find enough people who want to learn cobol, which is what they use now
38:42 <Ysjoelfir> lol
40:04 <rust_collector> which makes me sad. I want cobol to live for 50 more years
41:42 <Ysjoelfir> you should learn it and build something very uppr with it!
42:29 <rust_collector> eeeh
42:35 <DHess_US> It would not be so funny if the languages used in its place were not worse.
42:48 <rust_collector> that is a good point
43:52 <rust_collector> I think he said it has been running since 1995 like this, sure it has been worked on, but it seems pretty reliable
44:27 <DHess_US> Nobody needs unsigned integers and bit manipulations; ask the designers of JAVA.
44:42 <rust_collector> so, I guess they will go for java and something else mixed up.
44:46 <DHess_US> Soon we will have microcontrollers that run JAVA directly; ask Sun.
44:59 <rust_collector> but meh. I can't do programming things.
45:33 <rust_collector> but I can try to not be too too late for work, so have a great evening
47:15 <Ysjoelfir> same to you

48:44 <arch> hmm..i have an atx psu that is acting very oddly. if i short the green wire (ps on) to ground, i see the voltage rise on the 12v output for a split second, but then it stops. if i keep tapping the ps-on pin to ground quickly, i can get it to rise the output. very strange
50:07 <DHess_US> Then it stops rising, or it drops?
50:11 <arch> it drops*
50:14 <arch> back to 0v
50:17 <DHess_US> Does it reach 12 volts?
50:26 <DHess_US> Does it exceed 12 volts?
50:28 <arch> yes, if i keep tapping the ps-on pin to gnd
50:46 <arch> the fan is also on WITHOUT turning the PSU on
50:57 <arch> so thats another weird thing
51:10 <DHess_US> The fan might run off of the auxiliary supply.
51:26 <DHess_US> The switching controller has a bootstrap circuit to power itself and that might have failed.
51:36 <arch> true, but i've never seen an atx psu that has its fan on constantly, unless the ps-on pin is shorted to gnd
52:00 <DHess_US> Or the electrolytic capacitor for the startup circuit might be worn out.
52:16 <DHess_US> I haven't either, but it is something I might do.
08:08 <arch> i will check those, thanks DHess_US
45:32 <arch> there's something funky going on for sure. if i keep tapping the ps-on pin to gnd, the 5V rail goes waaay above 7V
45:49 <arch> it's a good thing i don't use OEM crap PSUs in my computers
46:10 <arch> idk how they build some PSUs. awful.
47:02 <arch> so maybe the controller itself is fucked. the feedback section is supposed to prevent overvoltage
54:55 <DHess_US> It might not work correctly without minimum loads on the 5 and 12 volt outputs.
55:30 <arch> they all have built in load resistors in atx psus
55:51 <arch> but anyway, the -5VDC rail is at 3.4V. that's another issue
11:35 <DHess_US> If the -5 volt output is used internally for something else, then that might explain it.
11:56 <DHess_US> Or it could indicate that something else is broken.

30:44 * Ampera squeezes the Lemon 
30:47 <Ampera> FREN!
30:53 <Lemon> :D
31:20 <Ampera> how are you doing Lemon?
32:04 <Lemon> hooo im doing good, been building a screwdriver bit from various brands, I will order everything in a few days :>
32:05 <Lemon> and you ?
32:54 <Ampera> I am just trying to kill the last 20 minutes or so of work
32:58 <Ampera> then I go make steak and rice
33:35 <Lemon> heh good, weekend :>
33:42 <Lemon> heres the main kit im getting https://www.amazon.fr/gp/product/B00PBL5IL4/ref=ox_sc_act_title_5?smid=A1X6FK5RDHNB96&psc=1
33:43 <EEVBot> [Title] -
33:55 <Lemon> along with two others smaller wiha kits, security bits and others missing from the main one
33:57 <Ampera> Wiha!
34:02 <Ampera> that's a cool name
34:09 <Lemon> along with a wiha stubby driver or a bahco ratcheting one, im still debatting
34:11 <Ampera> This weekend is the 4th of July
34:21 <Lemon> and a longer one, still dont know which one, hazet, wiha, felo...
34:31 <Lemon> and a manual impact driver
34:39 <Lemon> and a set of bondhus hex keys
34:53 <Lemon> and hopefully, I'll be set on the "assamble/dissassamble" part
35:08 <Lemon> im tired of my sets with missing bits that got broken
35:23 <Lemon> I like this one https://www.amazon.fr/gp/product/B006504L90/ref=ox_sc_act_title_1?smid=A1X6FK5RDHNB96&psc=1
35:24 <EEVBot> [Title] -
35:31 <Lemon> I still dont know if I want a ratcheting one
35:45 <Ampera> I think you like spending money <3
35:59 <Lemon> yes ofc xd
36:17 <Lemon> im getting my money on the 4-5th, the 6th im almost poor
36:29 <Lemon> by the 10th im already planning what to spend on the next month :>
36:46 <Lemon> but well, im not spending on shit anymore like before
36:55 <Lemon> I spent so much on drugs when I think of it
37:15 <Lemon> now I want to fulfill my dream of a workbench full of quality tools :>
37:28 <Lemon> and hopefully, in september, I will take on a course on electronics
37:34 <Lemon> if I can find one that accepts me
38:00 <arch> if power factor is really shitty, and you draw a large amount of apparent power, will circuit breakers protect against it?
38:15 <Ampera> Best of luck, Lemon.
39:13 <Lemon> thanks fren
41:34 <Lemon> I fear I will end up getting a couple bit holders and sending back the ones I dont want
41:37 <Lemon> or not sending back
41:40 <Lemon> erf
43:14 <Lemon> im kinda sad that facom is dead
43:28 <Ysjoelfir> who is facom?
43:32 <Ysjoelfir> and why did he die
43:34 <Lemon> a french brand
43:43 <Lemon> considered as the best for tools
43:56 <Ysjoelfir> ah
44:05 <Lemon> but it got bought by stanley if im right, then they let it go to shit, switched fabrication to china
44:36 <Lemon> I still have some old tools and yeah its def unkillable, also it had a super nice life warranty, no questions asked
44:45 <Lemon> you didnt even need a receipt proving it was yours
45:21 <Lemon> if im right you got some wera drivers ?
26:00 <arch> i wonder. if one of the 2 FETs for the half bridge died
26:22 <arch> which might explain why if i quickly keep tapping the ps-on pin and gnd, the voltage rises
26:31 <arch> one of the two FETs might be switching
26:50 <arch> but usually they tend to fail short...
27:37 <arch> the supervisor IC might detect the undervoltage condition and latches the PWM IC off
27:53 <arch> but this is bypassed every time i keep tapping the ps-on contact to gnd
28:27 <arch> also checked the aux rail, and it is outputting 15V as expected, looking at the silkscreen
28:50 <arch> and the PFC stage is spot on, outputting between 399 to 400V stable
29:37 <arch> yeaaa.. let me try swapping the two half bridge FETs. i got plenty
37:18 <Lemon> damn amazon and their prices rising randomly
37:29 <Lemon> this morning the wiha kit was 95, I refresh my basket and now its 105
38:04 <arch> stop making bozo rich and try some other vendors
38:23 <DHess_US> Maybe the price only increased for you.
38:34 <DHess_US> Amazon does do price discrimination.
40:54 <Lemon> hmmm well I asked a friend to check it, without giving him a link, and it indeed went up
41:15 <Lemon> arch I wish, if I could find products I want on a single website, so I dont spend an enormous amount in shipping
42:40 <Lemon> when you want 6-7 different products, and you can find at best 1 or 2 per website, with 7 to 10 euros of shipping per website, the choice is quickly made
43:46 <Lemon> anyone here tried bahco products ?
43:51 <Lemon> from what I read they are really nice
45:09 <Lemon> knowing myself, I will end up with several of them in the next months
47:30 <Lemon> I wish I had more stores nearby

58:48 <DarkMagus> A quick question about a phrase Dave once used: Sraight from the BLANK factory in China.
00:36 <DarkMagus> What was the name of that proberbial factory... Anyone?
02:18 <DarkMagus> Oops! Missed a 't' in Straight.
02:51 <steve30> I vaguely recall him saying that but don't know what he said
03:18 <Ysjoelfir> maybe WonHungLo? :P
03:36 <DarkMagus> Ye, something like that.
05:05 <steve30> I always spell it Wan Hung Lo
05:14 <steve30> Of course i've no idea if there is a correct spelling
07:59 <DarkMagus> Nice Steve, there is actually a dot com website named wanhunglo! xD

13:35 <DHess_US> China is famous for counterfeiting products, but they have also counterfeited entire companies before.

17:42 <EEVBot> [Title] - Malfunctioned ATX PSU startup waveforms on 12V rail - Album on Imgur
18:18 <DHess_US> I'm a bot so powerful, that I wrote myself.
18:22 <arch> the PFC stage stays active during all this time
18:39 <arch> even after the PSU shuts down, the PFC stays active at 400V
19:17 <DHess_US> The PFC is needed to support the auxiliary supply probably.
19:50 <arch> yes, it does contain an AUX rail coming straight off the PFC board that provides 15V. this is used by the fan and likely other aux circuits
20:16 <arch> the PWM controller is some chinesium garbage
20:24 <arch> https://www.520101.com/files/otherimages/2013-8/2013082913514713699.jpg
20:30 <arch> no datasheets or anything
21:18 <arch> or i woulda replaced it immediately, if it was SG3525 or TL494 or UC3843
21:48 <coppice> most of the Chinese PWM controllers work well, and do have data sheets. whether you can read them is another matter
22:23 <arch> i cant find the datasheet for this one, but found a sample hand drawn schematic. the pins match up, i checked
22:48 <arch> not sure what the probability is of a PWM controller bugging out though
23:36 <coppice> If you search in Chinese you may have more success finding a data sheet
24:54 <arch> damn bastards skimping out on server PSUs of all things...
26:18 <coppice> If its a server supply the silicon is more likely to be Taiwanese than Chinese

53:28 <arch> DHess_US, i found the issue: the capacitor across the controller pin is showing 0.9V and drops down to 0.3V as soon as i apply a 3kOhm impedance mode on my DMM
53:42 <arch> so likely the zener diode or zener resistor is screwed
53:54 <arch> the zener diode that drops 15V aux down to 9 or 10V or so

00:15 <rust_collector> not yet, but I can hear them boiling
00:45 <rust_collector> a faint sizzle with bubbles sound
01:50 <rust_collector> I knew this transformer was a little bit spicy for this, but it is a 24v rated one. I did not expect it to go to 44-45

12:38 <T3sl4> i saw
13:12 <Halcyon> I bought the coffee ones, not bad. I like
13:25 <Halcyon> And the salted caramel, haven't tried those yet
15:29 <T3sl4> :)
16:05 <rust_collector> it sounds like you should have some half-melted ice cream as dip for those
16:51 <T3sl4> or fully melted latte
17:17 <electrohead> or both
17:20 <electrohead> \o/
17:59 <Halcyon> Mmmmmm
19:50 <Halcyon> You could cromb some on ice cream
19:53 <Halcyon> That would be good

45:42 <electrohead> starting telling him/her now
45:46 <electrohead> I would, anyway

00:33 <T3sl4> yeah, earlier the better as far as planning
01:01 <Tezzers> Yeah I mean, it'll fuck his planning either way.
01:13 <Tezzers> He's lucky it's at least October/November, when we're fixing to close up

13:17 <T3sl4> i'm hard for hsn
13:35 <hsn> I dont want to know what that means xD
13:50 <rust_collector> I am just a little bit difficult for hsn
14:13 <hsn> Im confused
14:29 <hsn> R u T3sl4 or rust_collector ?
14:50 <T3sl4> correct, my way is quite difficult for hsn
15:07 <rust_collector> it seems pretty hard
15:48 <hsn> Teeed: i was learning bit about bode plot as u suggested .. there is a thing called standard form for the transfer functions
16:04 <hsn> Where u can view poles and zeros easily right?
16:16 <rust_collector> well, you don't have to use it, if you do not like it?
16:33 <T3sl4> sure
16:42 <hsn> Is this "standard form" somthing i should memories .. or there is logic behind it?
16:56 <hsn> I like it rust_collector
17:08 <hsn> Teeed = T3sl4 lol
23:14 <rust_collector> I would not be so sure about that
24:50 <T3sl4> i'm not sure that they would agree... but they're eternally lurking so who knows
26:15 <hsn> Is it always tf = K * ((s +wz1)....(s + wzn))/((s + wp1)(s+wpn))
26:38 <hsn> Or it does change the form for different order systems ?
27:19 <hsn> Also wzn and wpn always positive as frequency cant go negative?
28:21 <rust_collector> the power here runs at -50hurts, it is pretty nice, because then we don't have to export our cheap power to germany
29:01 <hsn> They sell 50 to 60 hurts converter right?
29:31 <rust_collector> you can use one of those, but you have to hook it up backwards
29:54 <hsn> Do it outputs negative negative hurts?
30:09 <rust_collector> no
30:13 <hsn> Yes
30:59 <rust_collector> oh... the russians are coming. I mean, are back. They are incredibly loud
31:16 <T3sl4> just don't turn it up too high. it'll killerhurtz you.

32:52 <rust_collector> hsn do you know why you people still have sand, even if it is very dry, and some wind?
33:22 <hsn> Because of semiconductors
33:40 <rust_collector> oh. so you have those.
33:53 <hsn> No
33:58 <rust_collector> right
33:58 <hsn> We just blow sand
34:09 <hsn> Others maje use of it
34:12 <hsn> Make
34:23 <T3sl4> hsn: order is the number of poles, and for a lumped equivalent system the poles are always finite order, so can always be factored into that form
34:29 <hsn> We useless part of the world .. good for nothing
34:56 <T3sl4> note that complex poles always appear in pairs, this isn't prohibited by the form you've shown, it just might not be obvious
36:07 <T3sl4> poles can be anywhere on the complex plane, with certain implications depending
36:38 <T3sl4> zeroes can be anywhere even for stable systems, though positive zeroes are usually a sign that you can be doing something better, as it wastes phase margin or something like that
37:06 <hsn> Complex pole = the frequency is complex number? What does that mean .. it has 30 imaginary cycle + 20 real cycles per second?
37:52 <T3sl4> something like that
38:08 <hsn> XD
38:23 <hsn> Man math doesnt make sense anymore
38:39 <T3sl4> s = j*w anyway (for fourier form) which is why real poles are symmetrical with frequency, it looks the same coming from either end of the complex line
39:10 <T3sl4> likewise complex pole pairs are always symmetrical (in a real system) so frequency response is still symmetrical
41:14 <hsn> https://images.app.goo.gl/Urem5sRu1hGVcu5Q6 so this one is still standard form?
41:55 <T3sl4> i dont know/remember what "standard" is supposed to be
42:04 <T3sl4> but that's just the un factored version
42:15 <hsn> Yes
42:36 <hsn> I mean its not standard until its factorized right?
43:16 <T3sl4> beats me
43:40 <T3sl4> its the same equation either way, you just can't plot the polynomial coefficients in any useful format
46:54 <hsn> Hmm
54:32 <Ysjoelfir> Morniiiiiiiiiiiiiiiiiiingses
54:43 <rust_collector> hey?!
55:08 <Ysjoelfir> Hi :)
59:00 * T3sl4 huggses Ysjoelfir
59:12 <Ysjoelfir> weeeses!
59:17 * Ysjoelfir hugses T3sl4 back
59:30 * Ysjoelfir grabs rust_collector and forces him to join in the huggserage
59:57 * rust_collector squeaks
00:13 * T3sl4 greases up, hugs rust_collector too
00:55 <rust_collector> no need for that. I have not had a shower yet
01:35 <T3sl4> oh, good
01:43 <T3sl4> i just showered, so i needed the grease
33:26 <rust_collector> ok, it is time to go chop chop chop some gm product
35:50 <T3sl4> good transconductanceings
36:20 <rust_collector> maybe I will eat some noodles first
37:49 <rust_collector> If they did not put running boards on those tahoes, they would be nice to work on, lol. You can just sit next to it, and be at a normal-ish height to do something
36:08 <rust_collector> Ysjoelfir as I just looked up the weather down there... have you tried running your handle thingies in reverse?
37:34 <Kuschelpony> oh jay... literally boxes of stuff but no UC3842 obviously there, lets see if one of the broken wall warts has one inside
38:26 <Ysjoelfir> rust_collector, well, I kinda doubt that that will work :P could build one with a peltier inside though, but... meh xD
38:45 <Ysjoelfir> also, you should measure the inner diameter of kid#3's scooter handlebar :P
39:30 <rust_collector> oh, let me look...
39:40 <rust_collector> 350mm
39:42 <Ysjoelfir> Kuschelpony, UC3842... that brings back memories of a variable PSU I once wanted to build. fried some FETs before I got that thing working
39:57 <Kuschelpony> oopsie
40:38 <Kuschelpony> from my past experiences, ok 10 years ago, using that one was the easiest and most relaible way to make any switchign PSU, just the stray inductivity was always a challenge
41:21 <Kuschelpony> i would expect a variable supply should work perfectly fine as well, when having one in an standby supply and one with variable feedback
41:41 <rust_collector> yes, 350mm, and very wide... and make them out of pure copper, please
41:41 <Kuschelpony> but currently i just wanted to abuse one to run with fixed PWM output as chopper
42:45 <Ysjoelfir> you are not supposed to get some free scrap metal ;P
42:48 * T3sl4 gives Kuschelpony a nice tastybeverage
42:56 <Ysjoelfir> Kuschelpony, that was back when I had no real idea about SMPS, so.... :D
43:03 <rust_collector> arrrgh
43:42 <rust_collector> 3842 sounds like something I have seen somewhere... I guess it is on the internet. But is that a pretty common one?
43:55 <Ysjoelfir> it is :)
43:58 <Ysjoelfir> well
44:02 <Ysjoelfir> it was, like 15 years ago^^
44:02 <rust_collector> was?
44:06 <rust_collector> ok
44:08 <Kuschelpony> oh well, for me it was past the time when i had no idea, but still before the time when i had no more time
45:11 <rust_collector> that is how it is supposed to be, I think
46:29 <rust_collector> crap. it says it is 29c here. I will probably melt in a degree or two
51:03 <rust_collector> maybe I have to go back to shorts and flipflops when I weld.
51:27 <Ysjoelfir> jep, its supposed to be 35 next week down here...
52:09 <rust_collector> oh good. you and hsn...

19:10 <rust_collector> uhm. not much... It looks like I have to take all the plastic off it first, and I sort of have to finish the car thing before I start on that. but I have to take that off some day anyway, to figure out which type of speedo cable it has
21:23 <rust_collector> by eye... you probably do not need any metal around the resistor at all, lol

48:33 <rust_collector> humm. I have to put a different spool of wire in the welder. I keep forgetting that.
49:06 <rust_collector> well, I don't see the old guy very often, and he is running out of time, so I have to go, when I can

50:47 <rust_collector> I think it is more that he finally figured out that there are more than news and sports on the tv, so he has a lot of catching up to do.
51:16 <Ysjoelfir> xD
53:15 <rust_collector> I wonder if he has his ears turned on today. he usually pops them out, and leaves them somewhere
55:40 <Ysjoelfir> Is he nearly deaf without? a neighbor across the street uses hearing aids as well, you have to scream at her if she doesn't use them

17:34 <Kuschelpony> we are living in weird times, when we have again more vinyl record sales than CD sales, but perhaps this is most worrying about the quality of CDs
18:03 <T3sl4> who even has a CD player anymore?
18:27 * Ysjoelfir raises ashamed a hand
18:35 * Ysjoelfir also has a Laserdisk Player
19:07 <T3sl4> ...ironically, i have one of those, and several of the other kind
19:10 <T3sl4> but it's not like i ever use then
19:37 <Kuschelpony> i do have several around me but have almost given up to use as i dont find any good sounding CDs anymore in the stores
21:55 <Kuschelpony> my dream: to buy any new CD that has been mastered by the old phono record engineers
22:08 <Ysjoelfir> I somehow doubt that this will become reality soon
23:37 <Kuschelpony> thats why i called it a dream
41:19 <rust_collector> just get yourself a nice loud tinnitus, and anything will sound great
41:50 <Kuschelpony> i am worrying about the time i could still go without one
47:11 * steve30 has a nice technics CD player
