00:00:36 <Lemon> well it doesnt work ?
00:00:39 <Lemon> while its clean etc
00:01:49 <Ysjoelfir> I have no idea how it's built, but I would assume that you could measure the different coils individually?
00:04:05 <hsn> (it doesnt work, while its clean) ---> just like circuits i design
00:04:09 <hsn> :)
00:05:39 <Lemon> im trying yes but it doesnt make sense to me
00:05:42 <Lemon> im looking the working one

00:19:10 * Ysjoelfir sits at work, enjoying the view of the fluctuations of his unconnected HP3456A
00:19:24 <Ysjoelfir> it's pretty interesting to see it drift when one openes a window
00:21:01 <Lemon> heh :>
00:21:04 <Lemon> I want one !
00:22:24 <Ysjoelfir> but I swapped my clicky plastic buttone one with the one with rubbery, spongy remote control like buttons :(
00:22:25 <K> a window?
00:22:44 <Ysjoelfir> yeah. those things that keep outside from disturbing you, K
00:23:12 <K> those things are great! i would suggest getting one with curtains though
00:23:30 <Ysjoelfir> usually they are made from glass and see-through style. but I usually like mine with something that blocks light from entering
00:23:33 <Lemon> why you swapped it ?
00:24:03 <Ysjoelfir> Mine was calibrated by dakks
00:24:07 <Ysjoelfir> we needed one with cal
00:24:22 <Ysjoelfir> so i got one of the uglier ones I repaired recently and put into storage
00:24:34 <Ysjoelfir> and gave "mine" to our cal lab
00:26:45 Join: Stiff ([email protected]) to #EEVblog
00:27:17 <Lemon> ho ok I see
00:27:24 <Lemon> also I have a question
00:27:32 <Lemon> what quick test can I do to see if the inductance box works ?
00:27:39 <Lemon> to see if its not the lcr meter fucking me up
00:27:44 <Lemon> I doubt it, but we never know
00:29:18 <Ysjoelfir> build an oscillator and measure it with your scope :)
00:29:31 <Lemon> is that hard ? :>
00:29:43 <Lemon> I mean, an easy test you know :>
00:29:47 <Lemon> something really rough
00:29:48 <hsn93> Xl?
00:29:51 <Lemon> just to see
00:30:13 <hsn93> and amplitude ?
00:30:28 <Lemon> but theres something weird
00:30:34 <Lemon> because on some ranges it reads 405mH
00:30:39 <Lemon> so it seems to work
00:30:45 <Lemon> I doubt its the meter honestly
00:31:21 <hsn93> cant u do ( VAC------(L)------(R)------GND) ? and do measure VR?
00:32:25 <Lemon> keep in mind im really beginning xd
00:32:27 <Ysjoelfir> he can, but he is just beginning :) so I would assume it would be nicer to see a waveform instead of just calculating it
00:32:44 <Lemon> but I dont think its the lcr meter
00:32:49 <Lemon> I mean it works fine for the other
00:32:50 <Ysjoelfir> I doubt that, too
00:33:02 <Lemon> and I get something on some ranges, always 400 something mH
00:33:03 <Ysjoelfir> but double checking is never a bad thing
00:33:16 <Ysjoelfir> and: as I said, I think you will like it :)
00:33:46 <Lemon> yeah I could try it thats true I dont know if it requires a lot of components or what
00:34:01 <Ysjoelfir> no, just a cap and a L
00:34:44 <Ysjoelfir> check this out :) https://www.testandmeasurementtips.com/basics-lc-oscillators-and-measuring-them/
00:36:17 <hsn93> loose probing ?
00:36:24 <Ysjoelfir> I wouldn't do that
00:36:30 <hsn93> loose coupling ** ?
00:36:34 <Ysjoelfir> but it explains the principle pretty good
00:37:43 <hsn93> so he builds antenna with (100x probe) ?
00:38:27 <Lemon> maybe solder joints are bad ?
00:38:29 <Lemon> is it possible ?
00:38:46 <Lemon> maybe they went wrong with time ?
00:38:47 <Lemon> idk
00:39:09 <Lemon> im gonna try to redo some to see
00:39:39 <Ysjoelfir> hsn: he basically does. but direct probing shouldn't be a problem. in this case it's only interesting to see if something changes while changing the inductance.
00:40:01 <Ysjoelfir> lemon: absolutely possible. remember from when and where this thing is
00:40:14 <hsn93> but direct probing wont kill the analyzer ?
00:40:49 <Ysjoelfir> no, why would it?
00:41:04 <Ysjoelfir> we're not talking about a high power RF oscillator
00:41:36 <hsn93> if it by mistake went dc ?
00:41:51 <hsn93> it doesnt ?
00:43:25 <Ysjoelfir> what problem would a scope have with dc?
00:43:39 <hsn93> oh i thought its spectrum
00:43:40 <hsn93> analyzer
00:43:58 <Ysjoelfir> nah.
00:44:05 <Ysjoelfir> he doesn't have one :)
00:44:26 <hsn93> if it was spectrum
00:44:45 <hsn93> u just put cap in the probe to couple ac ?
00:44:56 <hsn93> and start probing ? XD
01:01:15 <Lemon> ok so I redid some solder joints, nothing, then I desoldered a coil
01:01:17 <Lemon> and it measures nothing
01:01:25 <Lemon> well, a few uH like 0.6
01:01:40 <Lemon> there should be a 100, 200 and two 400mH
01:01:53 <Lemon> to make any numbers from 100 to 1100
01:02:24 <K> you broke it!
01:03:04 <Lemon> nah impossible
01:03:11 <Lemon> its really study and I never applied voltage to it
01:03:27 <K> but did you believe in it?
01:03:44 <Lemon> ofc
01:06:10 <hsn93> maybe didnt believe enough ?
01:09:43 <Lemon> im going to check another coil but I think something happened to it
01:14:16 <Lemon> ok second coil I check stills read shit
01:14:20 <Lemon> hrmmermremremer
01:16:23 <hsn93> so lcr problem ?
01:17:02 <Lemon> I just tried with a cheap component tester
01:17:07 <Lemon> it reads in the same range of value
01:17:12 <Lemon> so no I think something is wrong
01:17:27 <Lemon> maybe one coil is still good, or two, the 400mH ones
01:20:17 <Lemon> well I guess theres nothing I can really do
01:34:36 <hsn93> what music u suggest me to play?
01:35:08 <hsn93> anyone
01:35:26 <hsn93> EEVBlog Generate random music name

01:37:45 <Ampera> that works
01:37:47 <Ampera> avoid the new stuff
01:37:53 <Ampera> start with songs like Telephone Line
01:38:12 <hsn93> thats what i just opened
01:38:24 <Ampera> if you need just a list of songs, https://amperaa.net/cdn/musiclist.html
01:38:31 <Ampera> pretty much anything on there is good
01:38:35 <hsn93> hope its not 50Hz sine
01:38:37 <hsn93> :)
01:38:44 <hsn93> with high amplitude
01:39:43 <hsn93> https://amperaa.net/cdn/MisirlouAttempt1.mp3
01:39:47 <hsn93> ?
01:40:33 <Ampera> that's my own music, none of it is good
01:40:41 <hsn93> ampera i cant help it im watching your main.c
01:40:43 <Ampera> cdn is just my junk folder
01:41:11 <hsn93> some malloc without free is there
01:41:11 <hsn93> xD
01:42:18 <Ampera> yeah that's just an experiment I was working on
01:42:19 <coppice_> Ampera: Its time Jeff Lynn came out with a technology update for Telephone Line
01:42:27 <Ampera> coppice_, he did, calling america
01:42:34 <Ampera> satellite communications
01:44:47 <hsn93> https://amperaa.net/cdn/Render1.mp4 << which software ?
01:46:08 <Ampera> GIMP
01:46:16 <Ampera> and then compiled with DaVinci Resolve
01:46:23 <hsn93> Ampera, that indexing (cdn) page is not apache .. is it custom dynamic indexing?
01:46:55 <Ampera> it's apache
01:47:28 <hsn93> customized?
01:47:31 <Ampera> nope
01:47:32 <Ampera> stock
01:48:55 <hsn93> apache stock -> http://ameen.io/.well-known/ ?
01:48:57 <hsn93> like this one
01:49:15 <Ampera> yes
01:49:32 <Ampera> I didn't do anything to it, so maybe others have to theirs
01:49:38 <Ampera> it's just Apache on BSD
01:55:21 <hsn93> i want to enable index for specific folder
01:55:32 <Ampera> hsn93, thanks for reminding me to clean shit out of that folder :P
01:55:33 <hsn93> RewriteCond %{HTTP_HOST} ^foldername
01:55:34 <hsn93> Options Indexes
01:55:47 <hsn93> is this right?
01:56:39 <hsn93> Options +Indexes
01:57:37 <hsn93> nope it enables for all directories
02:01:06 <Ampera> no clue
02:01:13 <Ampera> I don't do much apache stuff
02:01:38 <hsn93> figured it
02:01:48 <hsn93> just make (.htaccess) for that specific folder
02:01:51 <hsn93> https://hsn93.com/www/
02:02:14 <hsn93> now how to make my index look like u ?
02:03:44 <Ysjoelfir> mine looks exactly like yours
02:03:44 <Lemon> I want to get an og snes controller + a pc adapter and play super metroid
02:03:56 <Ysjoelfir> http://img.tinkertubes.de
02:05:55 <hsn93> Ysjoelfir yep that the stock one i know
02:06:33 <Ampera> maybe Apache on BSD has a different default

02:06:45 <Lemon> perfect
02:06:55 <Lemon> I want one thats already used a bit, buttons respond better
02:06:59 <Lemon> they are burned in :>
02:07:07 <hsn93> http://img.tinkertubes.de/20180307_222538.mp4 << Ysjeolfir u suck at this game xD
02:07:33 <Ysjoelfir> weeeeelllllllllyes
02:09:03 <Lemon> someone here knows his shit snes wise ?
02:09:13 <Lemon> I wonder if pc adapter with og controller will get some input lag or not
02:09:32 <Ysjoelfir> just use a snes. waaaay nicer
02:09:43 <Lemon> yes I wish
02:09:50 <Lemon> but I dont want to get one + a tv
02:09:57 <Lemon> I know me, I will play a few hours and get mad
02:10:04 <Lemon> if I really git gud I'll get one
02:10:08 <Ysjoelfir> hehe
02:10:13 <Ysjoelfir> oh btw, lemon

03:04:57 <Ysjoelfir> tell me something exciting!
03:05:11 <Ysjoelfir> but please, ideally nothing involving poop
03:05:19 <Ampera> Ysjoelfir, I'm having Wendy's for lunch
03:05:32 <Ysjoelfir> uuuh ;) Is she sexy?
03:05:33 <Ampera> which will eventually turn into poop
03:05:38 <Ampera> uh
03:05:43 <Ampera> idk
03:06:47 <T3sl41> wait, i can answer both of these questions with one image

03:23:22 <Ysjoelfir> I found the reason for the different visual appearances of directory listings on apache
03:23:29 <Ampera> What is it
03:23:57 <Ysjoelfir> i found an option in my backend (cPanel). it now supports "Fancy" display and "Standard" display
03:24:16 <Ampera> but I don't use cPanel
03:24:20 <Ampera> my operating system doesn't even support it
03:24:38 <K> cpanel is for people who cant vim
03:24:54 <Ampera> vim is gay, emacs is better
03:24:57 <Ysjoelfir> I'm pretty sure that the option there just changes some flag somewhere - where exactly - don't ask me

04:55:05 <DHess_US> That must be one hell of a magnet.
04:55:35 <DHess_US> Modern hard drive media has such a high coercivity that demagnetizing it is really difficult.

07:00:04 <Ysjoelfir> Hi
07:06:04 <Ampera> hi Ysjoelfir
07:06:05 <Ampera> how are you doing
07:06:34 <Ysjoelfir> great! just came out of the shower after I found the isolation transformer in my hobby room to be on fire
07:06:46 <Ampera> ah
07:06:54 <Ampera> that sounds not good
07:10:11 <coppice_> well, if its isolated it shouldn't burn anything else :-\
07:10:57 <Ysjoelfir> well, it was just starting, so I was lucky
07:11:41 <Ysjoelfir> Luckily it didn't burn anything else, so I guess that is indeed a plus coppice_^^
07:11:58 <Ysjoelfir> but it was partly my own stupidity.
07:12:08 <Ysjoelfir> I didn't calculate all possible failure modes
07:12:20 <Ysjoelfir> and well, it failed in a manner I didn't take into account
07:13:25 <Ysjoelfir> the contactor that should have shorted the soft start resistors failed open. so the poor 4x10W resistors were cooking away. and since I mounted them on a piece of wood,... well.
07:19:01 <Ampera> Maybe you could market it as self-immolating
07:20:53 <Ysjoelfir> XD
07:24:33 <Ysjoelfir> https://drive.google.com/file/d/1N5jWq-p_mLMqRo3WkHCc5jhECxt4nxex/view?usp=sharing
07:25:10 <Ysjoelfir> it got so hot that they desoldered themselves
07:27:15 <coppice_> I've known ICs in DIP packages that were inserted the wrong way around melt their solder, fall off the board, and still be fully functional
07:28:01 <Ysjoelfir> oO thats pretty tough
08:06:06 <Ampera> toasty

08:20:34 <T3sl41> Ysjoelfir: so, you might not want to run those at, like, anything at all
08:20:39 <T3sl41> that wood plank isn't much of a heatsink
08:20:54 <Ysjoelfir> it was never intended as a heatsink
08:20:55 <T3sl41> and you might want to read the datasheet carefully for what the real power ratings are when not using an infinite heatsink :)
08:21:34 <Ysjoelfir> I didn't intend to use them at any (continuous) power at all. they are from the inrush current limiting of the 5kVA isolation transformer^^
08:21:56 <T3sl41> eesh
08:22:21 <Ysjoelfir> so the idea was: switch it on, resistors damp the inrush current, resistors get bridged nearly instantly -> not much power at all
08:22:40 <Ysjoelfir> worked for quite some time now. what failed was the contactor
08:23:26 <Ysjoelfir> which resulted in pretty toasty resistors as I connected the load, obviously
08:23:47 <T3sl41> when i do a precharge circuit i make sure to implement 1. a lockout delay to allow for charging, 2. a voltage sense to prevent the contactor from pulling in before the load is fully charged, and 3. a timeout delay to turn the whole thing off so that if 2 isn't met the resistors don't do that
08:24:15 <T3sl41> it's a PITA for lashing together, but i also haven't had to build many so i kinda don't care :P
08:24:28 <Ysjoelfir> exactly. As I wrote: [21:11:54] but it was partly my own stupidity.
08:24:29 <Ysjoelfir> ^^
08:24:48 <T3sl41> indeed :P
08:26:21 <T3sl41> but at least you've got a nice phenolic-charred wood incense burner
08:28:13 <Ysjoelfir> indeed i have^^
08:39:01 <Ysjoelfir> I thought about adding a thermal fuse in series. I have enough of those, so.... that should be an easy way. and using a big lightbulb instead of the resistors - if that thing gets all the power - who cares...
08:53:55 <Ampera> Blech, I'm done with work

09:11:21 <rust_collector> Nah, who knows?
09:16:00 <Ysjoelfir> good to know
09:16:11 <Ysjoelfir> i am so damn tired
09:16:15 <rust_collector> me too
09:16:41 <rust_collector> kid #1 is installed in his apartment, first night there for him
09:18:27 <Ysjoelfir> nice :) gratulations
09:19:20 <rust_collector> I had to call him, to hear where his hd power cables are, and by the sound, he was already sleeping
09:19:32 <Ysjoelfir> hehe
09:20:32 <rust_collector> but, it will be interesting to see how he deals with it
09:21:51 <Ysjoelfir> sleeping? nah, its not that bad
09:22:04 <rust_collector> are you sure?
09:22:05 <Ysjoelfir> actually its pretty easy
09:22:14 <Ysjoelfir> I'm sure he will manage it just fine
09:29:52 <rust_collector> so, what happened here today?
09:38:05 <Ysjoelfir> I nearly burned my hobby room down because of stupidity. other than that... nothing interestingf
09:38:25 <rust_collector> ok, that is something
09:39:05 <rust_collector> playing with flamethrowers are really best done outdoors
09:39:14 <Ysjoelfir> yeah, I noticed
09:39:40 <Ysjoelfir> https://drive.google.com/file/d/1N5jWq-p_mLMqRo3WkHCc5jhECxt4nxex/view?usp=sharing
09:40:12 <rust_collector> that is a really beefy fuse
09:40:46 <Ysjoelfir> :P
09:40:57 <Ysjoelfir> with smoke indicator
09:41:09 <rust_collector> soooo, what is that thing supposed to do?
09:41:37 <rust_collector> smoke signals have been used for many many moons
09:43:11 <Ysjoelfir> its the inrush current protection of my 5kVA isolation transformer. the contactor that was supposed to bridge the resistors failed, so the resistors were in series with the transformer while I pulled around 2kW out of it. they didn't approve
09:43:38 <rust_collector> ah
09:44:19 <rust_collector> I wonder if I still have those old train fuses somewhere... maybe you want one
09:44:51 <Ysjoelfir> if they look cool and arent tooooooooooo big, that could be a pretty cool thing to display :)
09:45:04 <Ysjoelfir> out of curiosity... lets calculate what those sweet resistors had to do
09:46:41 <rust_collector> they are... guessimating a bit, as I have not seen them in years... 60x40mm and around 250 to 300mm long. I think they were just some kind of stainless steel...
09:47:20 <rust_collector> just a block of steel, with a pair of threaded holes, so you could bolt on a handle
09:48:22 <Ysjoelfir> what rating did those have I wonder?
09:49:29 <rust_collector> I have no idea. if I got it right, they were sort of a backup, in the worst case sort of fuse, it was mounted on the roof, next to the pantograph.
09:49:46 <Ysjoelfir> the resistors should have been used well within their ratings, I assume it would be around 50 watts being dissipated in that fault condition. now if wood would be a great heatsink that is.... :D
09:50:01 <Ysjoelfir> aaah. so several kiloamps I guess?
09:50:14 <rust_collector> probably
09:50:43 <Ysjoelfir> thats pretty cool :)
09:51:10 <rust_collector> hmm, they run at... uuh, 16kv, I think. this was both old and not the most powerful train, but I guess, for a fuse, it was pretty stout
09:51:31 <rust_collector> so, what wood conducts heat best?
09:52:24 <Ysjoelfir> I am always searching for one of those old three phase mercury rectifiers.... I heard they were used a lot in train applications. that would be so awesome to get one. :) You know those?
09:52:30 <Ysjoelfir> hmm.. I assume burnt wood
09:52:57 <Ysjoelfir> so basically that thing decided to enhance its cooling capabilities, yay
09:53:50 <rust_collector> hmm, my train days were spent on old crap. I am not sure there were any 3 phase anything in them?
09:54:15 <Ysjoelfir> 3 phase mains to DC for trains I guess?
09:54:37 <rust_collector> you mean, at the "power station"?
09:54:42 <Ysjoelfir> yes
09:54:44 <Ysjoelfir> https://www.youtube.com/watch?v=latzy2NDcYg
09:54:49 <rust_collector> oh, well, i guess, maybe
09:55:09 <rust_collector> they did rum on ac here
09:55:38 <rust_collector> some odd number 15 3/4 hz or something
09:55:51 <Ysjoelfir> same here. 16.6Hz.
09:56:29 <Ysjoelfir> I have no idea if those rectifiers were realy used in train stuff, but I have heard that. :) however, I want one.
09:56:45 <rust_collector> 16 2/3hz
09:57:33 <rust_collector> They did have some boxcar sized rotary converters. they were pretty neat things
09:59:10 <rust_collector> there is one of those transformer stations a few minutes from here. they offered the local people and companies free heat, if they would lay the pipes, but no one wanted that, so they had to make the building 4 times bigger, to have room for the cooling stuff
09:59:29 <rust_collector> and no one uses the power... YAAY!
09:59:36 <Ysjoelfir> lol. idiots^^

10:10:41 <DHess_US> traction motors on trains were universal motors so AC or DC but with a variable field.
10:11:06 <DHess_US> That allows them to also be used for regenerative braking.
10:11:25 <rust_collector> right
10:19:06 <DHess_US> Can dynamic braking work with an induction motor? I guess if you put DC across it the energy is lost in the motor windings.
10:19:48 <DHess_US> I guess you would need a synchronous machine which is an induction motor with variable field to do that.
10:20:06 <rust_collector> I really have no idea
10:20:46 <DHess_US> https://en.wikipedia.org/wiki/Doubly-fed_electric_machine#Brushless_wound-rotor_doubly_fed_electric_machine
10:21:26 <DHess_US> Probably nobody uses those except for the highest possible power applications.
10:22:15 <DHess_US> A motor with electronic commutation has a limit in size which depends on how powerful the electronic commutation can be made.
10:22:43 <DHess_US> A doubly fed motor has no limit.
10:24:58 <DHess_US> Sort of like magnetic amplifiers; they also have no limit in size.
10:35:18 <Lemonizer> hmmmm im kinda interested of getting one of those gpsdo modules and building a nice accurate clock
10:35:48 <rust_collector> clocks do not need to be accurate
10:35:49 <Lemonizer> I wonder how far I can accurately go, nanoseconds ? maybe we can just digitize them, well estimate them once you get a stable 1hz signal ?
10:37:34 <Lemonizer> and I'll get to play with my 5345a :>
10:41:05 <Lemonizer> and use all those 7 segment displays
10:41:12 <DHess_US> The standard ones will be better than 1 microsecond
10:41:33 <Lemonizer> 1 uS would be dope already !
10:41:48 <Lemonizer> imagine, ho look its 12:00:000:001 ! :>
10:41:52 <Lemonizer> wait
10:41:58 <Lemonizer> 12:00:00:000:001
10:42:00 <Lemonizer> better
10:42:12 <Lemonizer> if I can get that with those 80-100 euros gpsdo modules, I sign !
10:42:30 <DHess_US> Better ones will be within 10s of nanoseconds over one second so say 0.1 PPM
10:42:32 <Lemonizer> maybe I can add nanoseconds for fun
10:42:40 <Lemonizer> 0.1PPB no ?
10:42:49 <DHess_US> No, .1 PPM
10:42:55 <DHess_US> 100 PPB
10:42:55 <Lemonizer> ha yeah from seconds, right
10:43:01 <DHess_US> No, for ONE second
10:43:09 <Lemonizer> yes for no from xd
10:43:11 <Lemonizer> please forgive me
10:43:12 <DHess_US> Over longer time periods, they are better.
10:43:15 <Lemonizer> but I get it !
10:43:30 <Lemonizer> I mean I could add nanoseconds even if its not perfectly accurate
10:43:36 <Lemonizer> that would be mostly for style
10:43:48 <Lemonizer> who am I to use micro/nanoseconds on a clock for something :>
10:43:58 <Lemonizer> besides styleeee
10:44:09 <rust_collector> how are you going to display that?
10:44:13 <Lemonizer> lemme look how many big 7 seg display of the same kind I have
10:44:46 <DHess_US> I used to have a Garmin GPS18 but a squirrel chewed the cable off and stole it.
10:45:26 <Lemonizer> hmmm seems I have at least 10-12 of the same size, which are like medium sized
10:45:32 <Lemonizer> and to display it well
10:45:37 <Lemonizer> I was thinking about that yes
10:45:46 <Lemonizer> I need some fastass chip
10:46:01 <rust_collector> you need some fast eyes too
10:46:12 <Lemonizer> ho np about that, as I said its mostly for fun
10:46:32 <Lemonizer> like 'hey check that, I got a clock that display accurate nanoseconds ! well, almost atleast'
10:47:05 <Lemonizer> if I show nano secs that would look like, for noon
10:47:13 <Lemonizer> 12:00:00:000:000:000
10:47:24 <Lemonizer> I need 15 of the same displays
10:47:34 <Lemonizer> thats no p roblem I think
10:47:34 <rust_collector> sure, but...
10:47:39 <rust_collector> arrgh
10:47:42 <rust_collector> have fun
10:47:44 <Lemonizer> dont ask why xd
10:47:49 <Lemonizer> I mean, its purely for fun
10:48:02 <Lemonizer> after like 10millisec it will be useless :>
10:48:05 <rust_collector> I think you are doing this just to annoy me
10:48:08 <Lemonizer> no one can follow that
10:48:14 <Lemonizer> whyyyyy
10:48:19 <Lemonizer> doesnt it sounds cool ?
10:48:36 <rust_collector> no. but if it is your thing, go for it
10:48:49 <Lemonizer> awww it sounds so cool !
10:48:56 <Lemonizer> will all those digits going blazin fast
10:49:02 <Lemonizer> like blkblkbklb
10:49:07 <Lemonizer> (the noise of digits going fast)
10:49:14 <rust_collector> yes, you might as well just put a led in the last 5 places
10:49:53 <Lemonizer> hmmm thats not wrong
10:50:02 <Lemonizer> it will look like, a *
10:50:04 <Lemonizer> 8
10:50:13 <rust_collector> yea
10:50:19 <Lemonizer> I wonder how many frames we can actually see, like irl
10:50:25 <Lemonizer> miliseconds np
10:50:32 <Lemonizer> microseconds might already be tough
10:50:33 <rust_collector> really?
10:50:38 <rust_collector> yes
10:50:38 <Lemonizer> not read them
10:50:41 <Lemonizer> just see the difference
10:50:46 <Lemonizer> like, a movement
10:50:56 <Lemonizer> not a purely stable digit, like a 8 on this instance
10:51:04 <Lemonizer> every segments of the display
10:51:10 <rust_collector> milli things sounds very small
10:51:28 <Lemonizer> well take a random chronometer, you can see a movement in the mili range
10:51:34 <Lemonizer> you cant read it
10:51:35 <Lemonizer> for sure
10:51:38 <Lemonizer> but you can see it moves
10:51:53 <rust_collector> ok, so, is it done soon?
10:51:54 <Lemonizer> im wondering at what level you cant see it move, when it becomes a 8
10:51:59 <Lemonizer> a led, like you said
10:52:17 <rust_collector> "yes, just wait 13:000000.00.00000:000"
10:52:44 <Lemonizer> haha yeah
10:53:55 <rust_collector> I really think you have a fetish confusion. you just like numbers. you should be into math, not things that can also in theory do things in long numbers
10:54:41 <Lemonizer> haha thats funny you bring that up because I talked about it earlier today ! I dont really like math at all, never liked it, but I like measurements thats true :>
10:54:49 <Lemonizer> I like to see long series of digits after coma
10:54:59 <Lemonizer> when I know they mean something
10:55:02 <Lemonizer> not random gibberish
10:55:09 <rust_collector> .........
10:55:52 <rust_collector> means someone had a bunch of 7 segment displays left over, and... might as well...
10:56:22 <rust_collector> they might be useless, but they are correct, if I could only see them
10:57:00 <Lemonizer> haha well I can always add a chronometer function :>
10:57:05 <Lemonizer> then I'll be able to see them !
10:57:28 <rust_collector> ok. get started, I will time you
10:57:33 <rust_collector> start NOW!
10:57:44 <Lemonizer> hmmm hmmm
10:57:46 <Lemonizer> but but
10:57:54 <Lemonizer> I need money to buy the gpsdo first !
10:57:56 <rust_collector> 13
10:58:04 <rust_collector> 20
10:58:11 <rust_collector> 28
10:58:16 <rust_collector> go go go
10:58:17 <Lemonizer> stop !
10:58:26 <rust_collector> that was quick
10:58:28 <Lemonizer> I get 32.320100405430543
10:58:32 <Lemonizer> is that alright ?
10:58:45 <rust_collector> it is within the 3 year specs
10:59:27 <Lemonizer> PERFECT
10:59:32 <rust_collector> no
10:59:36 <rust_collector> but not bad at all
10:59:38 <Lemonizer> well, good enough
10:59:46 <Lemonizer> ho also I fidlled with the systron donner
10:59:55 <Lemonizer> thanks again for the manual, it did help me find some stuff !
11:00:04 <Lemonizer> sadly, it still got a huge offset :/
11:00:10 <Lemonizer> it got a problem somewhere else
11:00:12 <rust_collector> did you find the sort of out of spec resistor yet?
11:00:41 <Lemonizer> I got it down from 23mv to 5mv, but it also have a linearity problem as between 10 and 13v, it grows from 5 to 8mv
11:00:59 <Lemonizer> other ranges are alright
11:01:03 <rust_collector> yes, did you find the out of spec resistor yet?
11:01:06 <Lemonizer> a tad outta specs but alright, I can live with it
11:01:16 <Lemonizer> ho no I dont even know if its a resistor
11:01:30 <rust_collector> well, you should probably find out!
11:01:31 <Lemonizer> it can be the adc chip or whatever is it called
11:01:33 <Lemonizer> the reference maybe
11:01:57 <Lemonizer> and one of the decade boxes are borked, I measured two of its inductors and it outputs almost nothing
11:02:03 <rust_collector> could be lots of things. do you feel like testing a resistor, or an adc chip or whatever?
11:02:31 <rust_collector> inductor box?
11:02:33 <Lemonizer> resistors well I could, but if its the reference or whatever, well...
11:02:43 <Lemonizer> yeah I have two inductor decade boxes
11:02:48 <rust_collector> oh, neat
11:02:53 <Lemonizer> they came from Ysjoelfir
11:02:58 <Lemonizer> along with a capacitor box too
11:02:59 <rust_collector> that bastard
11:03:07 <Lemonizer> 2/3 are fine
11:03:18 <rust_collector> and they look pretty
11:03:20 <Lemonizer> why ?
11:03:32 <Lemonizer> yeah they look nice its a shame one got a problem
11:03:37 <Lemonizer> maybe I can get new inductors for it, idk
11:03:42 <rust_collector> meeh, just because, why not?
11:03:50 <Lemonizer> yeah afterall why not
11:03:50 <rust_collector> yes, you probably could
11:05:35 <Lemonizer> it uses a 100, 200 and two 400 mH inductors
11:05:39 <Lemonizer> thats clever
11:06:05 <Lemonizer> if you want 700 you use in series the 200, 100 and 400, for 800 the two 400, and so on
11:06:17 <Lemonizer> thats better than using 9 different inductors
11:06:37 <Lemonizer> makes the switch a tad more complicated but well
11:06:57 <Lemonizer> 1/2/3/4 works too
11:07:19 <Lemonizer> ha no, as they are from 1 to 11

11:11:18 <Lemonizer> I was waiting for something else but well, that will do !
11:11:27 <rust_collector> BANANA!
11:12:22 <Lemonizer> thats better !
11:12:35 <Lemonizer> I wonder how many times per seconds a 7 seg display can refresh
11:13:09 <rust_collector> 3.333333333333333333333333333333333333333333333333333333
11:13:59 <Lemonizer> now it got me interested, which display is the fastest ?
11:14:09 <Lemonizer> lcds are not that great
11:14:17 <Lemonizer> TN's are the best but nowhere close as what I want
11:14:22 <Lemonizer> well, it dont exist
11:14:26 <Lemonizer> but which one is the closest ?
11:14:39 <rust_collector> those clicky ones at the gas station are not really great either
11:14:53 <Lemonizer> yeah lol imagine the noise
11:14:57 <Lemonizer> brrrrrrrr
11:15:14 <rust_collector> like any old corpsegrinder

19:55:00 <Halcyon> YAY! It's my weekend!
19:55:57 * Halcyon licks Ampera und Ysjoelfir
19:58:32 Join: meero ([email protected]) to #EEVblog
19:59:03 <Ysjoelfir> Hi Halcyon :)
19:59:07 <Halcyon> Hey mate, how you doing?
19:59:41 <meero> Hello
20:00:00 <Halcyon> Hey meero
20:00:13 <Ysjoelfir> great, being on work is lots of fun at the moment. :) Also, after I nearly incinerated my hobby room yesterday, I more or less finished that old WW2 radio
20:00:18 <Ysjoelfir> hello meero :)
20:00:28 <Ysjoelfir> And how about you Halcyon?
20:00:36 <meero> I came here wondering if you guys would know site or something that lists all chip logos
20:01:08 <meero> Im having hard time searching them
20:01:12 <Halcyon> Lucky you, work is boring for me
20:01:22 <Ysjoelfir> I have some of them in my favorites meero, one moment.
20:01:31 <Ysjoelfir> Nr. one http://rtellason.com/semiconductorlogos.html
20:01:48 <Ysjoelfir> Nr. 2 https://electronics.stackexchange.com/questions/334128/how-do-i-identify-smd-components-or-how-do-i-identify-any-component
20:01:51 <meero> oh shit thats perfect!
20:02:06 <Ysjoelfir> and nr. 3 https://www.westfloridacomponents.com/mm5/graphics/manufacturer-logos.pdf
20:02:12 <Halcyon> You find out all kinds of random stuff in here meero
20:02:40 <Ysjoelfir> but I'm pretty sure it's in no way complete, there are thousands of them out there, and many changed their logo over the decades
20:03:12 <meero> Haha! all the chips in my general radius, prepare to get TTL connection!
20:03:34 <Halcyon> Where you from meero?
20:03:39 <meero> finland
20:03:45 <Ysjoelfir> haha!
20:03:45 <Halcyon> Oh nice, my homeland
20:03:46 <Ysjoelfir> :D
20:03:49 <Halcyon> Have we spoken before?
20:03:58 <meero> nope, im first timer in here
20:04:09 <Halcyon> Well, not exactly homeland for me, I'm Finnish but live in Sydney, AU
20:04:21 <Halcyon> Finnish/Australian if you like
20:04:48 <Ysjoelfir> Halcyon: you want to see a pic of the nearly finished WW2 radio I was working on?
20:04:55 <Halcyon> Absolutely
20:04:59 <meero> cool, how's workmarket for finns in AU?
20:05:17 <Halcyon> Work here is generally good if you have skills. Work is everywhere.

20:06:12 <meero> smooth!
20:06:15 <Halcyon> What's the dial for? Tuning?
20:06:41 <Ysjoelfir> Rear after: https://drive.google.com/file/d/1MdBn0TKlDpYf7bvR0odB8Qz5hZYI-mGY/view?usp=sharing (the modern switch will be replaced as soon as I get a more fitting one)
20:06:48 <Ysjoelfir> yes, the dial is for tuning
20:06:57 <Halcyon> What do the numbers represent?
20:07:04 <Ysjoelfir> well..... :D
20:07:04 <Ysjoelfir> wait
20:07:05 <Halcyon> kHz ?
20:07:15 <Ysjoelfir> no
20:07:27 <Ysjoelfir> that would have been way to sophisticated for a radio that simple
20:07:54 <Halcyon> How's the weather in Finland? Nice and cold?
20:08:12 <Ysjoelfir> when you bought one of those you would get this piece of paper with it: http://www.imperatorrex.de/ve_images/dke_hilfsskala.jpg
20:08:19 <Halcyon> I have family in Helsinki and Tampere
20:08:33 <Ysjoelfir> There is a representation which station you could get on the red (long wave) and the white (short wave) scale
20:08:39 <Halcyon> Right
20:08:43 <Halcyon> Neat
20:10:10 <Ysjoelfir> sadly, the tuning capacitor is dead, so no working radio with this one. but meh, I wanted it for the fun repairing it, which I had. :) Now it looks gread again and can be placed somewhere.
20:10:40 <Halcyon> Could you not modernise it? Like include an aux in port?
20:11:23 <meero> Yeah its cold, there is also snow at least now.
20:11:58 <Ysjoelfir> I have actually thought about doing that, yes. replacing the tuning cap with a pot, so that it works as a volume control, and the two other ones for.... dont know. source selection, maybe add a small UKW radio module somewhere, and the other one as.... power switch or whatever
20:12:00 <Halcyon> It's been raining here all week. About 20-24C
20:12:04 <Ysjoelfir> woah, I want snow!
20:12:15 <meero> I hate when there isn't, it gets so dark when there is nothing to reflect
20:12:17 <Halcyon> Probably about 18C outside now @ 2012
20:12:33 <Ysjoelfir> we have just dirt and flimsy rain here in germany.
20:13:00 <Ysjoelfir> one day we had something simmilar to snow. suddenly everyone forgot how to walk and drive, the public trains shut down completely, and the next day - all gone
20:15:11 <meero> lol, I heard that also happens in uk
20:16:04 <Ysjoelfir> yeah, it's normal. we have maybe one or two days of snow each year, and all of the sudden everyone freaks out
20:16:09 <meero> back to that chip thing, is there any good places to search for datasheets? had pretty much no luck with google
20:16:31 <Ysjoelfir> I prefer datasheetcatalog. . . . .org? not sure right now
20:16:41 <Ysjoelfir> .net
20:17:11 <Ysjoelfir> usually if they don'7 have it, you will have a hard time finding one
20:17:54 <meero> thanks a ton!
20:18:04 <Ysjoelfir> you're welcome :)
20:18:20 <Halcyon> Ysjoelfir: Have you checked out YNAB yet?
20:18:34 <Ysjoelfir> I always help people that say hello when joining :P
20:19:07 <Ysjoelfir> Halcyon, no, I came back home very late yesterday (been at work for 11:30 hours..) and more or less went straight to bed after having dinner
20:19:20 <Halcyon> All good :)
20:19:41 <Halcyon> If you want to try the online version, they offer a month free trial (or 1 year if you're a student)
20:19:55 <Ysjoelfir> I guess I'll find the time today, I want to go home early for once :P
20:20:04 <Ysjoelfir> since I wanted to go to the gym today

20:22:06 <Halcyon> Excellent :)
20:23:21 <Ysjoelfir> Absolutely, especially for a person that was in therapy because of depressions for quite some time. :)
20:23:30 <Halcyon> *hug*
20:24:20 <Ysjoelfir> thanks :) But I think I'm stable now.
20:24:54 <Halcyon> Never too stable for a hug :)

20:25:51 <Ysjoelfir> Speaking of great things: I think about proposing to the gf this year
20:26:06 <Halcyon> Oh nice one
20:26:59 <Ysjoelfir> But I have no idea when and how. I am struggling with this "when and how" thoughts for some years now, but I decided to give myself the deadline of this year to finally do it^^

20:58:06 <Ysjoelfir> I do
20:58:18 <Halcyon> I guess?
20:58:30 <Ysjoelfir> I also thought about Norway, we absolutely enjoyed our vacation there
20:58:34 <Halcyon> I prefer sunny Australia
20:58:51 <Ysjoelfir> kssssssssssss, ssssssun!

20:59:13 <Halcyon> I live up in the mountains so we have lots of fog/low cloud
20:59:24 <Ysjoelfir> that sounds ok :)
21:00:05 <Halcyon> Tasmania is my favourite place
21:02:19 <Ysjoelfir> I never was there
21:02:27 <Ysjoelfir> nor in australia at all ^^
21:02:34 <Halcyon> If you ever come to Australia, add Tasmania to your list
21:02:46 <Halcyon> Particularly in winter if you like snow
21:03:15 <Ysjoelfir> Actually I would love to visit every land of this planet at least once :) But that won't happen. So.... we will see what can be done^^
21:05:59 <Halcyon> I think Ampera is planning a trip down here as well

21:45:10 <Ysjoelfir> I do, too. It's so comforting :)
21:45:18 <Halcyon> I'm going to have a relatively early one tonight
21:45:22 <Halcyon> I'm pooped after this week
21:45:25 <Ysjoelfir> I can't understand how people can say that they hate going to bed
21:45:33 * steve30 pets Halcyon
21:45:48 <Halcyon> I love bed
21:46:03 <Halcyon> The only thing I dislike about it is that I'm being unproductive while I'm there
21:46:43 <steve30> Unproductive? But sleep is important!
21:46:49 <Halcyon> Sure
21:46:55 <Halcyon> But I like to be productive
21:47:30 <steve30> Do you snuggle up with Mark in bed?
21:47:51 <Halcyon> Yeh but then I like to roll over and be on my own
21:48:13 <Ysjoelfir> For a moment I thought that mark is your bird :D
21:48:30 <Halcyon> No, that's Jerry
21:48:31 <Halcyon> :)

21:53:35 <Lemon> yeah its important, better sleep again when you are unsure you slept enough

22:15:26 <Lemon> Ishould get back into 3x3 cube solving
22:15:52 <Ysjoelfir> why that? you are already a pro lemon!
22:16:26 <hsn> does any one really understand how they solve it
22:16:37 <Lemon> ho far from that :> the lowest I went was around 35 sec avg of 5 which isnt really good
22:16:40 <hsn> as (3d space matrix) thingy .. not just (steps to do)
22:16:43 <Lemon> but I was more into modding than solving
22:17:09 <Lemon> well theres many methods but I use the CFOP if you want to look at it
22:17:11 <Lemon> its pretty simple
22:17:18 <Lemon> theres some algorithm to learn
22:17:27 <Lemon> and some other things you need to figure by yourself

22:58:50 <Lemon> hey Ysjoelfir, question for you ! how fast can a 7 seg display refresh per second ?
23:00:07 <Lemon> I want to build a clock with a GPSDO module, and I wonder if I show microseconds, if it will be fast enough at least to see a movement rather than a stationnary 8#
23:01:36 <rust_collector> hey and things
23:02:26 <Lemon> hi rusty
23:04:43 <hsn93> but why u want microseconds ?
23:04:56 <Lemon> ho purely for fun
23:05:09 <Lemon> and I'll maybe add a stopwatch function :>
23:05:23 <Lemon> its funny to say 'hey this clock is accurate to alllll those digits, and even more'
23:05:32 <Lemon> but I will be happy with milliseconds only
23:06:20 <Ysjoelfir> that depends on the display. Take a look into the datasheet :)
23:07:29 <coppice_> hsn: I'd have more faith in their figures if they didn't say SARS started in HK
23:12:32 Nick: hsn93 is now known as hsn
23:12:46 <rust_collector> well, it was invented in HK, why would they not say that?
23:12:58 <rust_collector> good lab people over there
23:13:00 <hsn> coppice_ everyone make mistakes?
23:13:04 <coppice_> invented? It came from China
23:13:19 <rust_collector> no no, it is carefully engineered
23:13:50 <hsn> its not engineered .. its (scientistsed) .. engineers are cool not harmful .
23:13:59 <Ysjoelfir> exactly. as well as corona is the result of those pesky 5G waves!
23:13:59 <rust_collector> uhm... well
23:14:07 <rust_collector> yes, like that
23:14:24 <hsn> oh dear hwuawei
23:14:31 <coppice_> The bastard that brought it to HK was a sick doctor who knew he had something new, had little chance of surviving, and couldn't give a damn about infecting huge numbers of people to get to the better health care in HK. He died anyway, but infected quite a few in the hotel where he stayed
23:14:34 <hsn> huawei .. what have u done
23:15:25 <Ysjoelfir> realy, we have some people here in germany stating that the virus appears only where 5G is active. That those 5G towers are only built in high population areas, where a virus can spread easily, doesn't correlate with that. It is absolutely obvious that 5G is the reason for the virus.
23:17:20 <coppice_> Ysjoelfir: repeat with me "correlation == causation, correlation == causation, correlation == causation". You'll never make it as a conspiracy theorist until you can that ingrained in you

23:18:53 <Lemon> and some other things but well
23:19:00 <Lemon> pic16/32 I think
23:19:40 <Lemon> will a micro be enough ?
23:19:43 <Ysjoelfir> Naaah, he won't. He is'nt like those idiots supporting the spread of 5G cells all over the world!
23:19:50 <Lemon> to display time down to miliseconds at least
23:19:56 <Ysjoelfir> don't start with pic. use atmel.

23:26:50 <K> you told something about fetching a fridge the other day, so i am cashing in the joke
23:26:57 <K> a day late, but still
23:27:04 <rust_collector> Nothing is as silent as teenagers having sex upstairs, while the parents are home
23:27:35 <Lemon> hmmm im thinking that for 9 7 seg displays, I need a lot of pins
23:27:42 <Lemon> or a chip dedicated
23:28:16 <rust_collector> fridge does not seem to run, but it jumps out the window just fine
23:28:46 <K> "it jumped on it's own, your honor!"
23:29:08 <rust_collector> yes yes
23:29:16 <Ysjoelfir> Lemon: Last advice before the meeting - there are things that are called shift registers. And another thing called Multiplexing :) google that, and you will be enlightened :)
23:29:34 <rust_collector> or bored
23:31:00 <hsn93> https://youtu.be/DgYGRtkd9Vs?t=284 ----> What’s an OSCILLOSCOPE? ELECtroboom has Keysight Wave 2020 draw
23:31:13 <Lemon> yeah Ive heard about those ! :> I have to dig in my fathers stuff, maybe theres some who knows !
23:31:27 <Lemon> but if the arduino itself can drive them, that would be nice
23:31:29 <Lemon> I doubt it tho

23:32:23 <hsn993> wtf with this network
23:32:50 <K> it makes you appreciate digits
23:33:53 <hsn993> why no isolating transformer in scopes?
23:34:11 <K> weight
23:34:30 <Lemon> well they already weight a ton
23:34:43 <rust_collector> your stuff weighs a ton
23:34:48 <Lemon> true yes

23:35:16 <rust_collector> the new ones are not forged from old train rails
23:36:12 <Lemon> I think the heaviest is the counter
23:36:15 <Lemon> its close to 20kg
23:36:35 <Lemon> the small gossen supply is quite heavy for its size, like 10kg easily
23:37:24 <rust_collector> but the counter and the power are not scopes...
23:37:45 <Lemon> yeah I was just talking about my 'stuff'
23:37:56 <Lemon> the tek 2245 is close to 10kg tho, so is the hp
23:38:15 <K> my dads C1-74 weighs around 40kgs
23:38:17 <K> bitch to move
23:38:25 <Lemon> what is it ?

23:39:04 <K> a ussr scope, true two beam, 50Mhz, modlar
23:39:05 <Lemon> hoooo pretty nice !
23:39:07 <Ampera> good morning
23:39:14 <Lemon> hello !
23:39:14 <EEVBlog> Hello there, Lemon!
23:39:23 <rust_collector> mornings Ampera
23:39:38 <K> prolly an inspired knockof of some hp series
23:40:42 <hsn993> thats it ? weight ? no other noise emi problem ?

23:41:38 <K> isolation is something you can add if neded, by default the devices should not be isolated
23:41:51 <K> and making it turn on/off complicates things and is confusing for idiots
23:42:16 <K> that is my take on it

23:57:13 <Lemon> hmmmm I have 9 of the same type (7 seg displays), big ones
23:57:17 <Lemon> and a lot of medium ones
23:57:31 <Lemon> I also have starbursts and stuff
23:58:43 <Lemon> I could use medium ones for the year/month/day, and big ones for hours/minutes/seconds/miliseconds
