00:11:07 * electrohead yawns and waves and things
00:21:38 * watcher waves back
00:35:40 <electrohead> hey mate
00:35:43 <electrohead> how goes it?
00:44:10 <watcher> good
00:44:36 <watcher> next week I will be less online
00:49:45 <electrohead> yeah I'm already less online, during the week
00:49:53 <electrohead> weekends are a different story
00:52:44 <watcher> I am monday and teusday not on late aussie time online and less then this week

02:25:27 <Ysjoelfir> mornings
02:31:09 * electrohead hugs Ysjoelfir with beer and hugs
02:34:08 * Ysjoelfir beers hug with electrohead and beer
02:41:46 <electrohead> :p
02:41:49 <electrohead> how you doing, man?
02:43:33 * watcher let a bear hugs Ysjoelfir
02:44:22 <Ysjoelfir> le man is doing in general quite good, but le man needs to reduce weight as his fatness is not helping much
02:44:30 * Ysjoelfir eats watchers bear
02:44:37 * Ysjoelfir thanks watcher for the feast
02:45:44 <Ysjoelfir> oh, electrohead, what I wanted you to do: I got some LEDs that I want to reverse engineer. maybe the you can find out if the software of the thing is.... reworkable, so I don't have to rebuild the whole thing?
02:45:46 * watcher makes a carpet out of the skin off the bear Ysjoelfir eats
02:45:59 <Ysjoelfir> woah nice! that will work nicely together with my cow!
02:46:27 <watcher> Ysjoelfir: have you eated a whole cow?
02:47:13 <Ysjoelfir> no. but I had the luck that I got my hands on a cow skin I glued to my floor: http://img.pdi.engineering/various/1667663181438.jpg
02:52:11 <electrohead> yeah I'm doing good as well. been staying busy with work, and I'm actually enjoying it
02:52:28 <electrohead> also for your project - what LEDs do you have, and what all did you do so far?
02:52:42 <electrohead> also, I like your green N64 :p
02:54:08 <Ysjoelfir> good to hear that you are doing better and actually enjoy work now :D what did change so that its now good?
02:54:17 <Ysjoelfir> and yeah, the green N64 is nice, isn't it?
02:55:18 <electrohead> well, I have to tell myself I like it; I mean, doing something I enjoy doing, and being paid for it?
02:55:23 <electrohead> yeah, life is pretty decent
02:58:00 <Ysjoelfir> thats what I personally would expect, yes :D having fun doing stuff you like is always nice
02:58:03 <Ysjoelfir> and the LEDs.... weeeeelll, its a small LED matrix, just 112x36 bright orange LEDs. from my company. an engineering sample. no schematics or anything. I just looked at it and was like "fuck this, can't read shit through the conformal coating!". but it has some STM micro on there, and since its an engineering sample,... maybe thats unlocked?

03:31:18 <watcher> i am out for todya
03:34:19 <electrohead> arch: rofl
03:34:41 <electrohead> Ysjoelfir: exactly what STM micro?
03:34:58 <electrohead> also, conformal coatings <3
03:35:03 <electrohead> I deal with them too much at work >.<
03:35:20 Quit: watcher ([email protected]) Ping timeout: 121 seconds
03:35:21 <electrohead> it always sucks to have to manually get that shit off, after three chemical baths do fucking nothing :/
03:35:42 <Ysjoelfir> No idea, they coated it AFTER adding a sticker onto the micro.
03:35:48 <Ysjoelfir> I can only read "ST"
03:37:20 <electrohead> is it the rubbery type of coating?
03:37:34 <electrohead> either way, did you try getting it off?
03:37:38 <electrohead> that's what I would do first
03:37:56 <electrohead> also, get me some pictures?
03:38:13 <electrohead> I have nothing going on today whatsoever, so I could have some fun time helping out :p
03:38:18 * electrohead cracks the first beer open
03:38:27 <electrohead> alcohol and electronics. what could possible go wrong? XD
03:39:24 <Ysjoelfir> its the freakishly hard stuff that you can only grind off.
03:39:37 <Ysjoelfir> let me get some licquor and try to pry it off somehow
03:39:44 <Ysjoelfir> and make some pics while I kill myself
03:46:21 <rust_collector> BOOM! is weekend
03:46:45 <electrohead> lol

03:47:44 <electrohead> yeah so the hard stuff you are talking about, is the shit I fight with all the time. I normally just very carefully pry it off with a nice pointy flathead screwdriver, and lots of hope lol
03:49:07 <electrohead> rust_collector: this is awesome.
03:49:21 <rust_collector> a good use for AI crap
03:49:37 <electrohead> yeah :p
03:51:25 * Ysjoelfir got beer and pictures
03:51:35 * Ysjoelfir sent them to the head and is now enjoying his beer
03:52:18 <rust_collector> I have been reading words and tables all day, so I do not need to drink today
03:53:11 <Ysjoelfir> electrohead, the processor seems to be a STM32F207ZGT6 or something like that?
03:53:27 <Ysjoelfir> why did you watch tables and words?
03:53:44 <rust_collector> I am in school again
03:53:51 <Ysjoelfir> oh, cool!
03:54:05 <rust_collector> not really. I do not really learn anything.
03:54:20 <rust_collector> every 5 years... same crap
03:56:01 <Ysjoelfir> aah, that kind
03:58:17 <rust_collector> well, I stopped seeing words, and it was just a pile of letters, so i went home
03:59:05 <Ysjoelfir> thats probably a good idea
03:59:29 <Ysjoelfir> oh, did you see the rays new show?
03:59:32 <Ysjoelfir> *shop
03:59:43 <rust_collector> nope.
04:00:02 <electrohead> oh, over signal?
04:00:09 <electrohead> that phone is charging, let me go turn that on
04:00:34 <rust_collector> play this old crap, while you do. it is neatly retro https://www.youtube.com/watch?v=88HkD_zB9mc

04:01:14 <Ysjoelfir> yes, it got signaled to you, electrohead
04:01:29 <Ysjoelfir> rust_collector - you should. he has a nice lamp in his toilet
04:01:53 <rust_collector> yes, I just have to realign my brain cells
04:05:24 <electrohead> wow, that's more complex than what I thought it would be
04:05:26 <electrohead> heh
04:05:34 <electrohead> I was thinking it was something small :P
04:05:37 <electrohead> (that's what she said)
04:05:46 <rust_collector> errrr
04:06:19 <Ysjoelfir> weeeeell....
04:06:36 <Ysjoelfir> 4032 LEDs, each one individually adressable,.....
04:06:40 <Ysjoelfir> yeah, its pretty tiny :)
04:07:13 <Ysjoelfir> the one I am working on right now (at work) has 43452 LEDs
04:07:19 <electrohead> individually addressable? nice :D
04:07:23 <rust_collector> the back of it looks a bit like military ant robots lined up
04:07:23 <electrohead> oh wow
04:07:27 <electrohead> that's a bit impressive
04:07:29 <electrohead> heh
04:08:12 <Ysjoelfir> if you didn't already notice what that was: its a train direction indicator thing. like, it says "S4 Hamburg" or whatever
04:11:57 <rust_collector> bad segeberg or new lebensraum. it is programmable, in some way
04:12:15 <rust_collector> neu, I guess... hmm
04:13:54 <Ysjoelfir> neuer ;)
04:14:02 <Ysjoelfir> oh, btw... speaking of bad segeberg...

04:16:49 <electrohead> Ysjoelfir: so, what happens initially when you power this up?
04:16:58 <electrohead> are there any serial and/or debug ports available?
04:17:01 <Ysjoelfir> it says "INIT" and thats it
04:17:06 <Ysjoelfir> how do I know that? :D
04:17:14 <electrohead> look for headers or connectors
04:17:14 <Ysjoelfir> oh you mean literal ports, hardware ports?
04:17:21 <electrohead> yeah, hardware ports of any sort
04:17:40 <Ysjoelfir> yes. I assume. as its an engineering sample, it should be programmable. one sec
04:17:52 <electrohead> *should be*
04:17:53 <electrohead> xD
04:18:57 <Ysjoelfir> it has a 10 pin (2x5) 50 mil header close to the crystal, so... I would guess thats it
04:41:37 <rust_collector> hmm, when a keyboard melts... that is not a good sign, is it?
04:43:03 <Ysjoelfir> nope. what did you do?
04:43:46 <rust_collector> well, it was that desoldering thingie.. I guess it was a bit too close
04:45:14 <rust_collector> that thing still does work pretty well. good times
04:46:53 <Ysjoelfir> nice :D
04:48:51 <Ysjoelfir> hah, I think I found out what the driver ICs for the LEDs are. the thousand ones on the black PCBs. seems to be these https://www.neumueller.com/datenblatt/macroblock/MBI5039%20Datenblatt%20-%20Datasheet.pdf
05:17:50 * arch drives Ysjoelfir with a gate driver
05:18:04 * Ysjoelfir gets driven
05:18:13 * Ysjoelfir lights up while doing that
05:18:18 * arch films
05:18:40 <electrohead> lol
05:18:51 <electrohead> yeah sorry about that delay, friend/landlord stopped over to pick rent up
05:19:04 <rust_collector> "rent"
05:19:06 <electrohead> I got showing him the start of the parts I'm bringing home, for the flight trainer
05:19:10 <electrohead> heh
05:19:42 <rust_collector> plane sneakers. that sounds fun
05:20:36 <electrohead> Ysjoelfir: so, I'd totally shoot voltages and such on the header, then stick the non-known power/ground pins on the o'scope
05:20:43 <electrohead> I'd totally start there
05:20:54 <electrohead> there's a chance you'll be able to control it over serial or something
05:21:33 <Ysjoelfir> the thing expects ethernet as its input. so I think the header will only be debugging or programming maybe?
05:22:02 <electrohead> ethernet?
05:22:27 <electrohead> well fuck yeah, have you hooked up it and discovered if it's setting a static IP, or requesting an address via dhcp?
05:22:50 <electrohead> I imagine you have used wireshark/tshark/tcpdump in the past, yeah?
05:24:45 <Ysjoelfir> I did, once, but I have no idea what I could do with that
05:26:06 <rust_collector> nothing like plugging in a train 1000V network cable to your confuser
05:26:59 <Ysjoelfir> heh :P
05:27:25 <rust_collector> should work, if you use hotdogs as resistors
05:28:38 <electrohead> lol
05:29:04 <electrohead> Ysjoelfir: so, have you tried hooking it up to your network, to see if it attempted to acquire an IP address?
05:29:13 <Ysjoelfir> nope
05:30:14 <Ysjoelfir> I connected it to the companies network. it shows INIT, and goes blank. but I couldn't check what it did of course
05:31:10 <electrohead> yeah I'd totally look into that
05:31:31 <electrohead> for all you know, the unit itself hosts a webpage or something, that gives you access to set messages and such
05:32:05 <Ysjoelfir> so you want me to reassemble it now and connect it to my router? ok, will do. but naaah, its not that sophisticated, trains have always some passenger information system that commands ALL devices.
05:32:23 <Ysjoelfir> so it will probably sit there, doing nothing and waiting for some valid package
05:32:24 <electrohead> no need to reassemble it just to test that :p
05:32:43 <Ysjoelfir> so.... how does it get its power than? :D
05:32:55 <rust_collector> aha! that is why that bus went missing. you want to simulate a train....
05:33:16 <rust_collector> great idea, trains at home are annoying
05:33:20 <Ysjoelfir> lol
05:34:02 <electrohead> lol
05:34:24 <electrohead> what do you mean, how does it get its power? you just said you powered it up, and it shows 'init'
05:34:26 <electrohead> ?
05:34:45 <Ysjoelfir> yes. at work. before I disassembled it when I took it home.
05:37:13 <rust_collector> not being very networky, I would think it has to register as a device, in some way, so I think wireshark or so is an idea. or maybe just go to the router settings, and see if it at least shows up as a thing?
05:37:31 <electrohead> ahh
05:37:35 <electrohead> well .. hook up power :p
05:37:53 * electrohead beers rust_collector's thing
05:38:29 <rust_collector> I guess it would connect to the network, as just a bare controller board? so you do not have to put all of the train in there?
05:38:52 <rust_collector> or is the other board the power?
05:39:06 <Ysjoelfir> we will see. I will finish watching this video and rebuild it.
05:39:15 <Ysjoelfir> it has a seperate PSU board that needs to be connected
05:39:57 <rust_collector> good to hear, that you are rebuilding that video, it is showing its age
05:40:08 <Ysjoelfir> XD
05:40:46 <rust_collector> an ysjoelf without wrinkles... hah
05:41:49 <electrohead> heh
05:42:21 <electrohead> Ysjoelfir: I'd assemble it partially, for the time being. just enough to apply power and see what you can find, via ethernet and such
05:44:02 <rust_collector> is we annoy him more, he will "log off" and make a new controller board, and have it use wireless power, over long distances, just because
05:44:27 <rust_collector> done by noon tomorrow.
05:49:43 <Ysjoelfir> that could be the case. :D I am not a big fan of code stuff as you know. but yeah, I reassembled it partially (of course I didn't put it back into the case, because.... no, too much hassle ;-) ) and plugged it in
05:50:02 <Ysjoelfir> so, if you are interested to see the init: http://img.pdi.engineering/Projects/LED%20Matrix/1667674099238.jpg
05:50:43 <Ysjoelfir> (that was under my insanely bright LED worklight, using 150 watts worth of daylight LED strips)
05:50:50 <Ysjoelfir> and thats with normal room light. http://img.pdi.engineering/Projects/LED%20Matrix/1667674099249.jpg
05:50:57 <Ysjoelfir> those LEDs are pretty nice
05:51:40 <rust_collector> you can make some happy looking unicorns appear on that
05:52:33 <Ysjoelfir> soooo... nope, does not appear on the router
05:56:20 <electrohead> yeah stuff is probably hard coded - have a spare laptop to use, for wireshark?
05:56:37 <Ysjoelfir> sure
05:56:43 <Ysjoelfir> what to do?
05:58:57 <electrohead> alright, windows or linux?
05:59:03 <Ysjoelfir> winders of course
05:59:10 <electrohead> fuck
05:59:12 <electrohead> alright :p
05:59:14 <rust_collector> dos for you
05:59:31 <electrohead> https://www.wireshark.org/download.html
05:59:31 <EEVBot> [url] Wireshark · Download | www.wireshark.org
05:59:50 <electrohead> now, I do want to ask - do you know how to set up a static ip address via windows?
06:00:29 <Ysjoelfir> of course. I may be a stupid idiot from time to time, but I did manage a whole companies network 10 years ago, and am actually doing that now again because nobody else can-ish
06:00:32 <Ysjoelfir> XD
06:00:35 <electrohead> XD
06:01:33 <arch> XD
06:01:47 <electrohead> just wanting to know, that's all. so ok, on said spare laptop, install wireshark, then set up a random static ip, just to enable your NIC, so to speak.
06:02:03 <electrohead> then run up wireshark, and start a capture on your ethernet device
06:02:17 <electrohead> it should automagically put your NIC into promiscuous mode
06:03:05 <electrohead> from there, you can power cycle the LED sign, and being in promiscuous mode, you will be able to see all packets of data
06:03:55 <electrohead> you'll have to possibly accept a minor learning curve, to understand what you will see; essentially, (we) want to see if the device has a hard-coded static IP or not, MAC address, and other possible details
06:04:50 <Ysjoelfir> it has a sticker on the processor board, saying "mac: 36" or whatever, so I assume the middle one. and I have nothing against learning stuff, IF I can do that :D
06:06:02 <Ysjoelfir> erm... needs a bit more time, this notebook I chose doesn't have an ethernet port.
06:06:10 <Ysjoelfir> let me grab another one
06:06:57 <electrohead> ok :p
06:07:19 <rust_collector> does miss mrs sister still need one?
06:09:11 <Ysjoelfir> yeah, why? did you rummage through the trash there again?^^
06:09:36 <rust_collector> no, I just realized that I do not use the one I had for me
06:10:19 <rust_collector> that one is pretty much the same. I also have 2 of them, that is one generation older, and not very fun
06:11:41 <Ysjoelfir> still better than nothing? the one I use now (or try to...) for the wiresharking is an old HP gaming thingemajig from 200.....5? thats just so insanely slow
06:12:27 <rust_collector> remove the rgb, and the stickers, and it will start behaving like a non-gaming machine
06:12:39 <Ysjoelfir> it doesn't have any of that
06:13:04 <rust_collector> oh, you got a chinese fake...

06:19:59 <electrohead> so we have possible ports to probe with nmap
06:24:56 <Ysjoelfir> ok, fourth time trying to download the stupid wireshark exe. its insanely slow downloading, and the file is corrupt if it doesn't abort
06:25:09 <Ysjoelfir> I think I look for another mirror
06:26:16 <Ysjoelfir> oooh, look at that, downloading it from chip is like 30 times as fast, and the file is not corrupt
06:26:33 <rust_collector> awww
06:27:30 <Ysjoelfir> aaaaaaaaand this machine is only 32 bit windows
06:27:41 <Ysjoelfir> i didn't even know that there was a 32 bit windows 7
06:27:48 <rust_collector> sure there was
06:27:57 <electrohead> heh, we have a laptop with win7 32 bit
06:28:05 <electrohead> but the CPU is 64 bit
06:28:07 <Ysjoelfir> I only used 64 bit afaik, so I wonder why this has 32 bit on it
06:28:07 * electrohead shrugs
06:28:07 <EEVBot> ¯\_(ツ)_/¯
06:29:00 <rust_collector> the elitebook thing came with 32 bit w7 pro. for some sort of business reasons. the license was good for 64 or 32 bit

06:45:48 <electrohead> so?
06:45:55 <electrohead> it works, yeah?
06:45:56 <electrohead> :p
06:47:12 <T3sl4> at least it's not a rPi ;)
06:47:18 <arch> lol word
06:49:57 <electrohead> rofl
06:50:06 * electrohead uploads linux into T3sl4's rectum
06:50:17 <electrohead> you just don't understand us linux freaks
06:50:19 <electrohead> err
06:50:21 <electrohead> wait
06:50:23 <electrohead> you just don't understand me
06:50:25 <electrohead> :p
06:50:36 <T3sl4> why would i want a buggy buttplug with a byzantine interface
06:50:58 <electrohead> hey, on a serious note - for oshpark, it says it accepts zipped gerber files; do y'all know what all files need to be included?
06:51:17 <T3sl4> everything you want on the fab :P
06:51:40 <steve30> sudo rm /T3sl4/buttplug
06:51:48 <electrohead> so literally all the files then? lol
06:51:55 <Ysjoelfir> I give up
06:52:04 <electrohead> fuck it, I'll just zip everything up
06:52:04 <Ysjoelfir> this notebook is utter garbage, totally unuseable in todays world
06:52:08 <T3sl4> usually put the fab outputs into a subfolder and just zip everything in that
06:52:35 <T3sl4> put, when generating them like
06:53:04 <electrohead> "We detected a 2 layer board of 1.59 x 4.58 inches (40.3 x 116.3mm)" --> 3 boards will cost $36.35
06:53:06 <electrohead> meh
06:53:16 <steve30> Not sure what the opposite of rm is for when Halcyon comes in
06:53:24 <electrohead> steve30: lol
06:53:42 <T3sl4> spending $50 for 10 boards is normal, not much point in skimping on qty they make like 12 panels at a time usually
06:55:38 * T3sl4 sudo apt-get install /steve30/buttplug
06:55:54 * Ysjoelfir installs a steve30-shaped buttplug into T3sl4
06:55:55 <steve30> :p
06:56:02 <steve30> :S
06:56:16 * T3sl4 installs a tesla coil shaped plug for Ysjoelfir
06:57:59 <arch> electrohead, if you have 3 weeks you can wait, just get em off jlcpcb
06:58:05 <arch> waaay cheaper
06:59:41 <electrohead> holy shit
06:59:48 <electrohead> yeah fucking way cheaper, dude thanks
06:59:52 * electrohead beer-hugs arch
06:59:54 <arch> i have used them many times
07:00:00 <electrohead> good quality?
07:00:03 <arch> hell yea
07:00:20 <T3sl4> well... no...
07:00:28 <T3sl4> but you probably don't need much
07:00:28 <rust_collector> I have used them one never. and they did a great job
07:00:34 <arch> T3sl4...do i really need to pull up you know what
07:00:55 * T3sl4 lets arch have a little fun
07:00:57 <T3sl4> (as a treat)
07:01:14 <arch> https://pbs.twimg.com/media/FHbJ5ZQWQAYU8TS.jpg
07:02:11 <arch> i have made pcbs with 6 mil tracks with them, ~40 tracks or no. all good, pcb worked as expected.
07:02:35 <T3sl4> trace quality is rarely a problem nowadays, 3 mil rules are common
07:03:00 <arch> ya..but we're not making space satellite power supplies like you are; we're happy with blinking LEDs with 555 timers
07:03:21 <coppice> T3sl4: 3 mil does cost more
07:03:41 <T3sl4> it's about mask flaking off, silk being blobby or misaligned, and drilling alignment
07:04:15 <arch> right..i am totally going to get a micrometer to measure if my board, which i paid $2 + shipping for, is up to 0.00001% spec
07:04:16 <coppice> not really. Most of the issues with fine traces are the traces being unreliable
07:04:32 <arch> :3
07:05:02 <T3sl4> arch: centering is usually 5 thou, if they're sloppier than that or you're using small vias, it's a big problem
07:06:50 <T3sl4> also, different quality of soldermask. protos are usually kinda translucent, scrape off easily
07:07:19 <T3sl4> though that can be more useful than not, for protos, in case you need to mod something
07:07:23 <arch> i believe you. i just think for the price paid, jlcpcb is more than enough for even super serious hobbyists
07:07:47 <T3sl4> well yeah
07:07:59 <T3sl4> i did say > T3sl4: but you probably don't need much
07:08:26 <electrohead> arch: lmao
07:08:35 <T3sl4> my issue is not with the fact that they'll make something usable, but that that counts as "hell yeah" as a quality metric
07:09:43 <electrohead> T3sl4, arch - so, I'm ordering PCBs for this - https://github.com/newaetech/chipshouter-picoemp

07:09:55 <electrohead> since jlpcb is way cheaper, y'all want a PCB?
07:10:10 <T3sl4> hobbiest hobbyist
07:10:30 <arch> im not even sure what that thing is electrohead lol
07:10:38 <arch> oh emi injection, never mind
07:10:45 <arch> i don't have a spectrum analyzer yet =(
07:10:50 <T3sl4> wtf are the slots for lol
07:11:17 <rust_collector> to add rgb
07:11:20 <arch> lol rust_collector
07:11:29 <electrohead> lmfao
07:11:49 <electrohead> arch: tough shit, I'll be sending you a PCB once these show up :p
07:11:52 <electrohead> T3sl4, you too
07:13:43 <T3sl4> meh, i have better ways to make EMI
07:13:48 * T3sl4 farts on electrohead
07:14:18 <electrohead> yeah I do as well, but I just want to experiment with the chipshouter
07:14:20 * electrohead shrugs
07:14:20 <EEVBot> ¯\_(ツ)_/¯
07:14:23 <T3sl4> like, if i want to do pulse discharge from this i guess i could https://www.seventransistorlabs.com/Images/HVPower2.jpg (2kV 10mA adjustable supply)
07:15:04 <electrohead> mmmm, sexy
07:15:08 <electrohead> just like you :p
07:15:31 <arch> :D
07:15:42 <T3sl4> jesus fucking christ full voltage across a tact sw
07:15:44 <arch> what input voltage does that use T3sl4
07:15:46 <T3sl4> what idiot made this
07:15:50 <T3sl4> arch: 12V or so
07:17:29 <T3sl4> electrohead: so what, it makes a pulse of a few us risetime? that's rather unimpressive
07:17:46 <T3sl4> i guess if you want to trigger ESD latchup on an unsuspecting victim you could use it for that
07:18:47 <arch> we should hire T3sl4 as an EE dominatrix. he can belittle us with his superior designs and we can learn a lot.
07:18:48 <T3sl4> and the driver transistors have diodes in series? w....why??
07:19:35 * arch makes T3sl4 whip electrohead with litz wire
07:19:53 <T3sl4> 4000 strand-lashes with a wet coppernoodle
07:20:02 <T3sl4> wait, how many strands do i have on hand anyway, not sure
07:20:16 <T3sl4> i have some like 4AWG equivalent somewhere, not sure how many that is
07:20:36 <electrohead> well, I'm getting into voltage and clock based glitch attacks more and more, and EMP based attacks are interesting and intriguing. the picoEMP is a good start
07:21:28 <arch> ok, time for me to get out. i shall return in a few hours
07:21:37 * electrohead beers arch one last time
07:22:19 * rust_collector
07:22:39 * T3sl4 glances at rust_collector
07:23:19 <rust_collector> hey!
07:24:44 <electrohead> random question - references for editing gerber files and such?
07:26:06 <electrohead> I *think* kicad is a good option ?
07:27:39 Quit: arch ([email protected]) Ping timeout: 121 seconds
07:28:57 <electrohead> ahh, hrmm, after reading up, I'm looking at this wrong
07:29:25 <rust_collector> I think you want the changes before it is gerberised?
07:29:45 <rust_collector> but, i dunno? it is probably possible
07:30:11 <T3sl4> editing gerbers is generally kind of suck
07:30:28 <T3sl4> even altium sucks at it, but that may be for other stupid reasons
07:30:52 <electrohead> I see

07:32:11 <electrohead> hrmm
07:33:27 <rust_collector> you can probably use vi, and some clever things
07:44:56 <electrohead> yeah I need to sit down with kicad one of these days, to understand it better
07:45:07 <electrohead> for the time being, I'll just get the PCBs made, and make manual edits
07:45:10 <electrohead> no biggie
07:54:22 <rust_collector> yes, is only small
08:11:52 <electrohead> yeah so that's ordered
08:12:04 <electrohead> and, I also ordered ingredients for my next batch of beer <3
08:16:57 <rust_collector> BOOOO!
08:28:55 * electrohead slaps rust_collector
08:38:43 <rust_collector> that is cute
08:51:22 <electrohead> <3
08:51:24 <electrohead> feel the love lol
08:51:42 <rust_collector> it is not often I get slapped by a handsome young man
08:51:51 <electrohead> you know it, babes.
08:55:22 <coppice> rust_collector: so, you don't fight too many duels

11:07:08 <coppice> yeah, caffeine is the perfect fix for insomnia
11:11:33 <LiIonMusk> For sure. Nothing like staying awake to try again the next night.
11:12:10 <electrohead> caffeine is king
11:12:31 <LiIonMusk> Baileys is queen
11:12:50 <LiIonMusk> electrohead: do you like ... baileys?
11:14:14 <electrohead> that's good in coffee, heh
11:14:33 <LiIonMusk> How about ... from a shoe?
11:15:11 <electrohead> o.O
11:15:19 <LiIonMusk> I got some watercolors. You want to look at my watercolors?

22:05:54 <Ysjoelfir> exactly
22:06:27 <electrohead> sure
22:06:29 <electrohead> lol
22:06:29 * Ysjoelfir deyawns electrohead
22:06:37 * electrohead dies
22:07:23 <T3sl4> wait, why is it 5 o clock again
22:07:30 <Ysjoelfir> https://www.neumueller.com/datenblatt/macroblock/MBI5039%20Datenblatt%20-%20Datasheet.pdf those LED drivers look easy enough to drive, I think I will just make new driver boards for the drivers and a new controller board. should be easier to figure out than finding a notebook that wants to talk with the thing

22:08:29 <electrohead> I just had to go around and change time on like, 10 fucking clocks
22:08:32 <electrohead> guh
22:09:01 <electrohead> Ysjoelfir: you know, you could also live boot linux from a usb stick, and use wireshark in linux. might be easier?
22:09:27 * T3sl4 rubs on electrohead
22:09:45 * electrohead charges up T3sl4
22:10:10 <Ysjoelfir> yes, I could do that. But I am annoyed by that. I might try that when I am finished doing an own design
22:11:02 <electrohead> you could always send me the old driver board, if you wish
22:12:24 <Ysjoelfir> if you want to play around with it?
22:12:34 <electrohead> yup :P

23:04:21 <electrohead> Sounds like that thread needs a closing
23:04:39 <jaymax> Yea
23:06:50 Join: coppice ([email protected]) to #EEVblog
23:07:37 <jaymax> Yesterday I listened to a CBC radio segment where the hosts were lamenting about the Twitter purchase and it's subsequent loss of free speech and safety. I cannot help but think of an entirely different group of people having that same lament three years ago, except this time nothing meaningful has changed compared to a month ago.
23:09:06 * electrohead shrugs
23:09:06 <EEVBot> ¯\_(ツ)_/¯
23:10:43 <jaymax> Yup. Twitter was a dumpster fire a decade ago, continues to be now, and will continue to be in a decade from now. The very format is shit for useful human engagement - it is structured to draw the worst out of people.
23:12:16 <electrohead> "This thread is a train wreck. " fucking LOL
23:12:26 * electrohead claps for whoever that is
23:23:17 <coppice> jaymax: taking over something like twitter is ultimately not going to make you look bad. Its suck a turd that no changes could really make it worse.
23:23:25 <coppice> such a turd
23:24:49 <coppice> jaymax: someone who left twitter some time ago said the 140 characters thing, which at launched seemed to be to make it SMS like, was actually chosen to make reasonable conversations nearly impossible
23:26:08 <electrohead> The worst part about that - From time to time, I come across interesting-as-fuck projects, .. just to discover they were posted on twitter, across the span of like, 20-some messages.
23:26:13 <electrohead> So frustrating and stupid.
23:31:27 <K> that thread should be locked
23:31:45 <K> it has gone completely ass.
23:32:24 <coppice> lock K up, and throw away the key, like a crypto coin that's founder has died
23:33:17 * electrohead locks K in the closet, and throws coppice away from the key
23:33:37 <K> is it a nice closet?
23:35:10 <electrohead> yeah it should be
23:36:18 <steve30> hi
