00:18:33 <rust_collector> what does it do, when you do something to the reset pin?
00:19:26 <Lemon> well Idk I just tried a circuit but I get shit
00:23:10 <rust_collector> was it a shit circuit? if so, congrats, you did it

00:51:54 <rust_collector> hello, Lemon
01:25:19 <Lemon> so theres this thing
01:25:24 <Lemon> fucking discord is out of my screen
01:25:29 <Lemon> and I cant bring it back
01:25:32 <Lemon> ive tried everything
01:25:52 <Lemon> the shift/click + arrow keys, playing with disconnecting my screens etc
01:25:53 <Lemon> nope
01:26:44 <rust_collector> trrrrricky
01:28:44 <K> task manager to the rescue

01:31:52 <rust_collector> no no! stop quitting people, go to the discord thing first
01:48:00 <hsn> can i count on this as microstrip capacitance ? https://www.emisoftware.com/calculator/microstrip-capacitance/
01:52:49 <rust_collector> good question. can you think of any reason it would not be?
02:16:25 <hsn> i dont know , maybe for example it works on sophisticated pcb not fr-4 regular supply ..
02:16:53 <hsn> or whatever,, i've seen a lot that makes me question every new information .. :')
02:16:59 <hsn> trust issues
02:18:03 <rust_collector> sounds good. I hope someone has an answer for you
02:22:56 <hsn> i just assumed its good and converted it to excel :P
02:23:21 <hsn> https://snipboard.io/nf9JQC.jpg
02:23:31 <rust_collector> there is probably some cases where xxx is yyy, because reasons
02:25:53 <hsn> ok cool one more question .. do i need to tell (pcb house) this is impedance control stuff or i can just take their stackup thicknesses + height and consider its flat accurate stuff
02:26:47 <rust_collector> hey, wait! someone has to answer first....
02:26:53 <rust_collector> I have no idea
02:27:15 <K> they should be able to tell you what they can provide
02:27:26 <K> with tolerances and stuff
02:27:36 <rust_collector> I can dig holes, and run a forklift, or whatever.... not this stuff
02:28:01 <hsn> yes K, this is enough right : https://snipboard.io/2EJwzL.jpg ?
02:28:37 <hsn> u drill holes via ?
02:29:15 <K> haven't done any impedance controlled stuff myself eh
02:29:30 <hsn> K, that thickness +/- 10% means i've error 10% in all thicknesses + dielctric ?
02:29:49 <hsn> hmm
02:29:53 <K> to me the error would apply to whole stack
02:30:26 <hsn> right ,, i think it came from (plating + some compressing done at some stage) ..
02:30:37 <K> as an 1st order aproximation that would relate to impedances as well
02:31:38 <hsn> 2. When copper thickness increases, the dielectric layer will be reduced correspondingly.
02:31:52 <hsn> holy cow :)
02:32:05 <K> if you want to dig into this, a book "High Speed Digital Design: A Handbook of Black Magic" is quite good
02:32:36 <hsn> no no no no digging anymore :(
02:32:40 <hsn> i'll get fired xD
02:32:45 <K> bhh
02:33:15 <hsn> i do slow speed stuff yet i search about this stuff at work time for fun .. no one knows what is required from me
02:34:36 <K> well, i would argue that knowing about high speed stuff is good for slow speeds too
02:39:20 <hsn> the question is (do i know enough in slow analog electronics)? .. answer : no :P
02:39:56 <K> you know enough that there is such thing
02:40:02 <rust_collector> can you blink a led, without an arduino?
02:41:51 <hsn> yes at 1Hz
02:41:54 <hsn> with my hand
02:41:54 <hsn> xD
02:42:22 <rust_collector> ok, sorry, but you are overqualified. good luck
02:42:57 <hsn> well, with (google = multi vibrator circuit of npn + RC) .. but i cant do it alone i think i will struggle
02:43:10 <hsn> or wien bridge oscillator using lm358 ..
02:43:17 <hsn> but i would google them
02:44:19 <rust_collector> well, that is how the web part of the world seems to work, so...
02:45:13 <hsn> thats how programmers use stuckoverflow ? :P
02:45:22 <rust_collector> mmhmm
02:46:06 <rust_collector> so, I suggest you make a valve led blinking circuit. that seems unusual enough
02:46:48 <rust_collector> it is also very hipster like, imo, but we do not have to mention that
02:51:05 <hsn> valve??
02:51:21 <rust_collector> uh, vacuum tube?
02:51:33 <rust_collector> old radio sort of things?
02:52:35 <K> mechanical valve
02:52:40 <hsn> this stuff is expensive
02:52:41 <hsn> right?
02:52:53 <K> vacum tubes?
02:52:54 <rust_collector> depends... does not have to be
02:53:02 <K> somewhat
02:53:12 <K> not for mass production if you mean that
02:53:18 <rust_collector> depends on your local pile of junk
02:53:33 <rust_collector> who would..
02:53:34 <rust_collector> heh
02:53:44 <hsn> (there is no local pile of junk)
02:53:55 <rust_collector> I guess someone would buy a thing like that, lol
02:54:09 <hsn> ebay has a lot
02:54:33 <rust_collector> oh, then you just have to discover it. there has to be a pile of junk somewhere
02:55:19 <rust_collector> i think you can get some tubes, that runs at normal low voltages. I guess the transformer would be sort of expensive
02:56:45 <rust_collector> but yes, I have no idea. but I think that would be such a stupid idea, that it would be sort of cool
03:00:45 <hsn> there is no (dump yard) stuff here .. like how dave goes shopping xD
03:01:00 <hsn> people through stuff directly to trash .. everything
03:01:21 <hsn> i dont know how (trash managment) then and (sorting) works ..
03:01:27 <hsn> in this country
03:02:09 <rust_collector> there you go. it has to be somewhere
03:06:03 <hsn> http://www.tradearabia.com/source/2014/07/08/project.jpg
03:07:46 <rust_collector> yes, just look for new islands just off the coast
03:15:03 <hsn> c u guys
03:15:05 <hsn> take care
03:24:36 <K> you too
03:43:02 <rust_collector> NEVER!!!

18:43:45 <hsn> hello there, Ysjoelfir
18:43:47 <hsn> !
18:44:44 <hsn> my note on the design: + checkout the stolen color :P https://snipboard.io/Gf79eO.jpg
18:45:17 <hsn> sry small picture https://snipboard.io/sj0co9.jpg
18:47:53 <Ysjoelfir> That looks nice hsn^^
18:48:44 <hsn> thanks
18:48:49 <hsn> how r u? all good?
18:48:57 <Ysjoelfir> even though I absolutely HATE the font altium uses as a standard. Imho it's too big and I don't like serifs. I switch mine always to Tahoma.
18:49:45 <hsn> tahoma is nice
18:49:54 <hsn> do u switch from options ?
18:53:37 <Ysjoelfir> yes
18:53:45 <hsn> i think its not in GUI
18:53:47 <Ysjoelfir> but
18:54:08 Join: AndrevS ([email protected]) to #EEVblog
18:54:34 <hsn> seems like i have to change it from a setting txt file
18:54:37 <Ysjoelfir> it is. options (that wheel symbol), schematic, ... erm.... dont know how the next point is called as I don't have my altium on this work PC. T3sl4?
18:54:52 <Ysjoelfir> its... standard primitives or something like that, don't remember
18:55:06 <Ysjoelfir> I just tend to load my saved options as soon as I reinstall altium for whatever reason
18:55:20 <hsn> don't have my altium on this wor
18:55:29 <hsn> https://snipboard.io/TnlZ2Y.jpg
18:56:22 <Ysjoelfir> also note, that the fonts are additionally saved in the part... so if you change it now, all "old" parts will still use altiums standard font and color...
18:56:30 <Ysjoelfir> [08:55:19] <hsn> don't have my altium on this wor
18:56:37 <Ysjoelfir> whut? did it break at that point? Oo
18:56:48 <Ysjoelfir> [08:55:29] https://snipboard.io/TnlZ2Y.jpg
18:56:53 <Ysjoelfir> just click on one of the primitives^^
18:57:09 <hsn> yes still same
18:57:46 <hsn> https://snipboard.io/SDAlPG.jpg
18:57:51 <hsn> i will restart to check now
18:59:31 <Ysjoelfir> thats strange. T3sl4 do you have any input here?
18:59:41 <Ysjoelfir> Are you even at the pc? :P
19:00:02 <hsn> T3sl4 is missing for few days i hope he is well
19:00:25 <hsn> it worked
19:00:47 <hsn> https://snipboard.io/jQW7t9.jpg
19:02:41 <hsn> i guess making options gui for such details is boring so they just put the path of the options file :P
19:02:44 <Ysjoelfir> nice. if you now change the color to black and the size to 8 I would be super happy :D or better, that would be what I personally prefer.
19:02:56 <Ysjoelfir> well, in my altium there is a gui^^
19:03:06 <hsn> mine is old i guess
19:03:28 <Ysjoelfir> but i don't use altium designer, it's... circuit...... maker? studio? that non free, 500€ thing
19:03:34 <hsn> black .. for printer?
19:03:48 <Ysjoelfir> I just don't like that dark blue, thats all.
19:03:55 <hsn> yes its good same thing but they strip shortcuts
19:04:26 <Ysjoelfir> exactly. and since I can't afford thousands of euros for the full thing I have to use what I can afford
19:04:34 <hsn> a girl wouldnt accept "dark blue" .. its called NAVY
19:04:56 <hsn> 500 euro is for year ?
19:05:39 <Ysjoelfir> WOAH sorry!
19:05:41 * Ysjoelfir bows
19:05:50 <Ysjoelfir> I just don't like NAVY color, I prefer black
19:05:59 * Ysjoelfir hopes that mrs. ysjoelfir doesn't kill him
19:06:58 <Ysjoelfir> the 500€ is the initial cost. in addition there would be the annual japodawdwdwjdw
19:07:01 <Ysjoelfir> wad

19:11:50 <Ysjoelfir> it's his fault https://drive.google.com/file/d/1VpFOQVtZlGv35bUsi8lil76q0dUdMG3P/view?usp=sharing
19:18:49 <hsn> oh nice
19:19:30 <hsn> are you putting milk in key number 2 for him
19:19:30 <hsn> ?
19:20:14 <hsn> + i dont understand why u use qwertz keyboard :(
19:20:29 <hsn> to undo u press (ctrl + y) ?
19:21:20 <Ysjoelfir> no, he doesn't like milk. He is just exploring this new room he usually has no entrance to.
19:21:46 <Ysjoelfir> But since I do home office he knows I'm in here and mrs. Ysjoelfir isn't at home, so he stands in front of the door and scratches on it
19:21:58 <Ysjoelfir> so I decided to let him in
19:22:20 <Ysjoelfir> we u8se ctrl+z for undo and ctrl+y for redo
19:22:29 <Ysjoelfir> or ctrl + shift + z for redo sometimes
19:22:56 <hsn> oh my color in irc is same as my new altium theme
19:23:22 <hsn> so our ctrl+z is much faster = we are more error prone ..
19:29:39 <Ysjoelfir> xD you think so?
19:42:14 <hsn> well thats why everyone is saying german engineers are on different level :P
19:43:05 <hsn> i ll start suggesting to remove z from the company keyboards on next meeting
19:43:06 <hsn> xD
19:44:36 <Ysjoelfir> Hehe :) I think I should realy stay with that slogan mamalala suggested for my website XD
19:44:44 <Ysjoelfir> Tell me how your meeting went then :P
19:52:07 <hsn> dude
19:52:23 <hsn> yesterday we have video confrence the boss background was beach
19:53:09 <hsn> https://pbs.twimg.com/media/C8GvSc9XkAMVR_a.jpg like this one
19:54:26 <hsn> it was little funny .. he insisted on using zoom app .. i think thats why xD
20:00:59 <Halcyon> Evening all
20:03:50 <hsn> evenying halcyon
20:03:54 <hsn> evening
20:15:49 <Ysjoelfir> lol^^ nice.
20:15:51 <Ysjoelfir> hi Halcyon
20:16:12 <hsn> Ysjoelfir, slagon? website?
20:16:24 <Ysjoelfir> yes
20:16:32 <hsn> Just leave it to the kraut!?
20:16:42 <Ysjoelfir> yes
20:18:34 <Ysjoelfir> what do you think Halcyon?
20:18:44 <Halcyon> Hm?
20:19:12 <hsn> its cool sentence :P
20:19:36 <Halcyon> What kind of website?
20:19:47 <hsn> the good kind, halcyon
20:20:08 <hsn> pdi.technology
20:20:29 <hsn> tinkertubes.de
20:21:24 <Halcyon> Is this your business?
20:23:14 <Halcyon> What about "PDI.Engineering -- Tinkering with Scheisse since 2020"
20:23:19 <Halcyon> :P
20:24:01 <hsn> Scheisse = lady gaga?
20:24:13 <Halcyon> Whatever the word for "Shit" is then :P
20:24:24 <Ysjoelfir> xD
20:24:29 <Halcyon> Or, "Don't turn it on, zieh es auseinander!"
20:24:58 <Ysjoelfir> it is my business, yes. but i never had a website and think about how to start it now.^^
20:24:59 <hsn> there is series im watching on netflix called dark
20:25:14 <hsn> thats the only place i hear german words .. its hard language
20:25:46 <Ysjoelfir> xD
20:25:49 <Halcyon> You should watch Hogan's Heroes hsn :P That's where I learn most of my German
20:25:56 <Ysjoelfir> Eigentlich sit es eine sehr einfache Sprache, hsn :)
20:26:01 <Ysjoelfir> *ist
20:26:52 <Ysjoelfir> Das faszinierendste ist, dass sich deutsch für andere anhört, als würden wir uns dauernd beleidigen. Für uns ist es das genaue Gegenteil. Arabisch etwa klingt für uns wie wilde Flüche :D
20:27:29 <hsn> accroding to google translate: Die Aussprache ist schwer
20:28:31 <Halcyon> https://youtu.be/DQWPU7N_EGg?t=9
20:29:16 <Ysjoelfir> well, the same is true if I try to speak arabic^^ it's a way my mouth is not used to move, so.... it's hard :D
20:41:10 <hsn> Ysjeolfir: https://youtu.be/9kxL9Cf46VM?t=124
20:44:42 <Ysjoelfir> XD
20:46:32 <hsn> actually i wanted to share : 6:20 ^^
20:46:35 <Ysjoelfir> interesting to see that there is one big group of people with those completely white clothing and that head....gear....cloth thing whichs name I don't know
20:46:50 <Ysjoelfir> and one group of people waring more western clothing^^
20:47:50 <hsn> hehe
20:48:49 <Ysjoelfir> very very very nice :D i had a good lough^^

20:51:00 <Lemon> guess who formated the wrong usb key yesterday ?
20:51:10 <Halcyon> Good on ya
20:51:17 <Halcyon> Did you recover your data?
20:51:21 <Lemon> that key being the freaking bootloader of the workstation
20:51:29 Join: hsn93 ([email protected]) to #EEVblog
20:51:42 <Ysjoelfir> why do you do such a thing? :D
20:51:46 <Lemon> I spent three hours to fix it !
20:51:49 <Lemon> gahhh
20:51:56 <hsn93> sry disconnected
20:51:57 <Halcyon> And what have you learned?
20:51:59 <Lemon> and then my anne pro was locked in fn mode !
20:52:06 <Lemon> dont press both alt buttons
20:52:09 <hsn93> hey lemonada
20:52:10 <Lemon> another fucking hour
20:52:13 <Halcyon> What else?
20:52:20 <rust_collector> hey nerds
20:52:28 <Halcyon> Hey rust_collector
20:52:31 <Ysjoelfir> woah, now the whole goup comes in
20:52:33 <hsn93> hey rusty whatsup
20:52:38 <Ysjoelfir> hi Lemon, hi rust_collector, wb hsn
20:52:43 <Lemon> and as I have multiple screens, most things were out of it
20:52:45 <rust_collector> hi hi hi hi hi
20:52:52 <Lemon> another hour to fix it because of fucking windows
20:52:55 <Halcyon> I think this is the good time of day where it's not too late here, but not too early on the other side of the world
20:53:15 <rust_collector> installing a real os does not take an hour
20:53:20 <Ysjoelfir> it's around 11 in northern europe^^
20:53:32 <Halcyon> EEVblog time
20:53:46 <Halcyon> Dammit, Ampera, where did the bot go?
20:53:53 <rust_collector> the bot has a vhyrus
20:54:01 <Halcyon> COVID-19?
20:54:11 Quit: hsn ([email protected]) Ping timeout: 121 seconds
20:54:11 <rust_collector> I dunno?
20:54:51 <Lemon> so yeah, dont format the wrong usb key
20:55:08 <rust_collector> why do you have the bootloader on usb?
20:55:19 <Lemon> because this mobo doesnt support nvme
20:55:26 <Lemon> so theres a workaround with clover
20:55:44 <rust_collector> heh. so you mmhmm riiight ok well haha then
20:56:15 <Lemon> and that usb key is in my case, directly on the motherboard's debugging usb
20:56:18 <Lemon> so I dont touch it
20:56:25 <Lemon> yesterday I had to format a key, so I looked at the size
20:56:35 <Lemon> checked if there was any other connected, nope
20:56:40 <Lemon> both were 16gb
20:56:49 <Lemon> and when I rebooted, black screen :>
20:57:08 <rust_collector> I wonder if plop supports nvme
20:57:59 <Ysjoelfir> whatever plop is, i like its name
20:58:19 <rust_collector> a bootloader, that used to be put on a floppy
20:59:11 <rust_collector> often used to boot live usbs, when the machine does not do booting from usb
20:59:53 <Lemon> hey you know the guy who own the leapsecond website
21:00:02 <Lemon> he got hydrogen masers
21:00:10 <Lemon> but arent those like, ultra expensive ?
21:00:20 <Lemon> in the hundred thousands ?
21:00:25 Join: Nico ([email protected]) to #EEVblog
21:01:14 <rust_collector> I have no idea who this is, but lots of expensive stuff is just thrown in the bin when the project is done. That could be a thing
21:01:42 <rust_collector> you do not want to sell it to your enemy, better throw it in the art bin
21:02:29 <Lemon> yeah but we are talking about the most precise frequency standard
21:02:36 <Lemon> its no randomito thingie
21:03:04 <rust_collector> ok, then you REALLY do not want your comprtition to get it
21:03:18 <Nico> Hi all, may I bother you with a beginner question regarding my rigol ds1054 scope? I'm measuring a PWM signal that varies its duty cycle. I want to figure out what the highest duty cycle is over time. Can this be done?
21:04:57 <Lemon> hmmm I think the rigol should have a function to measure duty cycle, at least the maximum
21:05:10 <Ysjoelfir> let me check
21:05:13 <Lemon> my 27 y/o tektronix does it
21:05:14 <rust_collector> I would think so, but I have never even seen a rigol
21:06:18 <Ysjoelfir> yes
21:07:24 <Ysjoelfir> choose with the left horizontal readout meno + and - duty (and whatever you need in addition to that.
21:07:41 <Ysjoelfir> then go on measure - statistic - switch that to on. you will get now not only the current values, but also average, max and min

21:08:32 <Ysjoelfir> @ Nico
21:09:14 <Nico> yes! got it (I missed the bit about statistics...) thanks!
21:09:58 <Lemon> damn that sounds complicated
21:09:59 <rust_collector> sadistics
21:10:24 <Lemon> I hit the button measure, then select duty cycle, max/min
21:10:31 <Ysjoelfir> youre welcome
21:10:38 <Lemon> http://www.leapsecond.com/ten/clock-powers-of-ten-tvb.pdf
21:10:45 <Lemon> really interesting btw
21:10:57 <Lemon> I didnt thought that mains frequency is that accurate
21:11:16 <Ysjoelfir> Lemon - its pretty easy actually. but in this case the screen space shrinks, so you can choose if you only want the info for the current signal or all info you can get
21:11:52 <Lemon> ha yeah I see, theres black parts on my display reserved for infos I think
21:12:11 <Ysjoelfir> it isnt accurate. at least not short time accurate. but if you see it long time , it's pretty darn good^^
21:13:43 <rust_collector> now I want to wife the world with a cloth, and wait for its core to cool down
21:13:57 <rust_collector> wife? wipe...maybe
21:13:57 <Lemon> yeah long time accurate
21:14:05 <Ysjoelfir> xD
21:14:16 <Lemon> just wife it
21:14:25 <rust_collector> wife the world!
21:14:58 <rust_collector> I bet that is legal in some states
21:15:11 <rust_collector> you can wife as many worlds as you like, actually
21:18:01 <hsn93> no
21:18:05 <hsn93> u only wife 4
21:18:57 <hsn93> does wife have plural in english?
21:19:00 <hsn93> wives?
21:19:15 <rust_collector> I think so
21:19:34 <Lemon> yes wives
21:24:52 <rust_collector> I can not listen to you, mr we don't have junk in my country
21:26:58 <Lemon> what ?
21:27:22 <rust_collector> no, the other guy
21:27:49 <rust_collector> hsn says junk does not exist down there
21:28:12 <rust_collector> something about genies flying away with it at night, or something

21:34:11 <Ysjoelfir> :D
21:35:10 <Ysjoelfir> I am wondering what i should make for dinner this evening. I still have one sweet potato I want to use. ideas?
21:36:24 <rust_collector> boil it until it turns into gloop, and use that water to get stains off textiles? go get a pizza
21:37:37 <Ysjoelfir> xD
21:37:55 <Ysjoelfir> nah. it's a biger one. I think its eough for a meal for two
21:37:56 <Ysjoelfir> https://drive.google.com/file/d/1W1fvhSaSM-RrPIp_y5a2yMWIm8_a0zKc/view?usp=sharing
21:37:59 <rust_collector> shred it, and put it into a stew?
21:38:06 <hsn93> rusty, no no no .. i ment there is (yard where u can get old radios or tv or devices) ..
21:38:29 <hsn93> dumb yard its called?
21:38:40 <hsn93> dave have lots of videos of what he found in that
21:38:47 <rust_collector> yes, the genies take all that into their bottles, or lamps, or wherever they live these days
21:39:01 <rust_collector> the dumpster room?
21:39:04 <rust_collector> naah
21:39:22 <hsn93> yeah that
21:39:47 <rust_collector> Ysjoelfir, isn't it time you make a cut across your finger also?
21:40:21 <Lemon> the leapsecond guy must be somewhat wealthy
21:40:38 <Lemon> those cesium hp standards runs for what, couple thousands ? he got like ten of them
21:40:44 <Lemon> and two hydrogen masers
21:40:49 <Lemon> those are the price of my house, easily
21:41:08 <hsn93> https://snipboard.io/bhFocd.jpg
21:41:10 <rust_collector> no, he just has a ton of expensive crap. he probably has to eat noodles, like the rest of us
21:41:38 <Lemon> nah like really
21:41:42 <hsn93> leap second guy : http://leapsecond.com/ ?
21:41:44 <Lemon> its the next level
21:41:47 <Lemon> yeah
21:42:03 <Ysjoelfir> [11:39:47] <rust_collector> Ysjoelfir, isn't it time you make a cut across your finger also?
21:42:04 <Lemon> I could own a cesium standard if I save up for a few months and spend nothing else
21:42:06 <Ysjoelfir> I thought about that
21:42:10 <rust_collector> Ysjoelfir, I give up, make chips
21:42:13 <Lemon> but an hydrogen maser, noway
21:42:18 <Ysjoelfir> xD
21:42:27 <Ysjoelfir> sweet potato chips
21:42:29 <Ysjoelfir> sounds great
21:42:35 <Lemon> accurate to 4x10e-15 per day
21:42:43 <rust_collector> hipsters say it is good
21:42:45 <Ysjoelfir> but a bit unhealthy. Halcyon won't approve i'm sure!
21:43:08 <rust_collector> he can not get there these days anyway
21:43:08 <Halcyon> Heh
21:44:23 <Ysjoelfir> maybe you have another idea^^ somehow I am thirsting for something healthy. i know, strange, but....
21:44:50 <rust_collector> pine cones...
21:45:37 <rust_collector> you said you wanted to use that blob potato. you did not say anything about healthy, until Halcyon was watching
21:46:59 <K> hello
21:47:25 <rust_collector> khello
21:47:37 <Ysjoelfir> lol^^
21:47:41 <Ysjoelfir> hello K
21:47:45 <Lemon> shit now I want a rubidium standard
21:47:46 <Lemon> hell K
21:47:48 <Lemon> hello K
21:47:50 <Ysjoelfir> "now"?
21:48:03 <Lemon> well I was like 'ok this gpsdo will be fine'
21:48:06 <Lemon> but now....
21:48:25 <rust_collector> shit, I want a bhubarb standard NOW!
21:49:47 <Lemon> measurements are what I really like honestly
21:50:21 <rust_collector> make your own standard. if you only use that, it will work
21:50:37 <Ysjoelfir> I want a fluke 792 now.
21:51:02 <rust_collector> for some reason, I want one of those process meter things
21:51:13 <rust_collector> I like processing some times
21:51:34 <Lemon> nice thingies Ysjoelfir !
21:52:10 <K> NO TOUCHIGN!
21:52:47 <rust_collector> remote touchscreen... that could be a thing
21:56:09 <Lemon> I really want to see how the accuracy of my siglent gen will be improved with the gpsdo module

22:24:42 <Lemon> Id like to find one of those on day
22:24:44 <Lemon> one
22:25:00 <Lemon> they are really precise and can be used as an AC voltage source, for example
22:25:00 <EEVBlog> Someone forgot to turn me back on
22:25:07 <rust_collector> there is one on ebay...
22:25:17 <Lemon> yeah but I dont have the funds
22:25:19 <rust_collector> arrrgh. that someone....
22:25:33 <rust_collector> well, no, but you found it
22:25:46 <Lemon> get not find
22:25:48 <Lemon> sorry
22:25:57 <rust_collector> awww.
22:26:16 <rust_collector> I was hoping you got the thing you wanted, lol

22:26:52 <Lemon> look at this nice boi
22:27:01 <Lemon> it even does the coffee
22:27:07 <Lemon> accurate to 0.0001%
22:27:39 <rust_collector> who cares. as long as it makes plenty of coffee
22:28:40 <rust_collector> those are not bad, for being a chinese thing with a fruke sticker
22:29:12 <rust_collector> Includes Carrying Case & Accessories
22:29:18 <rust_collector> that sounds nice
22:33:21 <Ysjoelfir> my ex employer had five of those

22:33:42 <Lemon> they are impressive
22:33:43 <rust_collector> 5 bags?
22:34:53 <rust_collector> Lemon, I think you might like to watch this, even if it is not electronic
22:34:57 <rust_collector> https://www.youtube.com/watch?v=hR599E7g7QY
22:38:00 <hsn93> hey Ysjoelfir, does cross-hairs have to match footprint centre origin ?
22:38:20 <hsn93> or assembly houses ignore cross-hairs actually?
22:39:03 <Ysjoelfir> what crosshairs do you mean?
22:40:41 <hsn93> https://snipboard.io/42SwOX.jpg
22:40:44 <hsn93> the green one
22:41:30 <hsn93> some of my footprints have cross-hair that doesnt match (component origin): https://snipboard.io/kSeaF6.jpg
22:42:10 <Ysjoelfir> ah. I don't place those. usually assembly houses either use center origins or they just reference fiducials and adjust their machinery for the parts
22:42:12 <hsn93> how does pick and place machine knows where to pick the chip from = the green cross hair right?
22:42:53 <hsn93> so they go component by component and put center cross?
22:43:40 <hsn93> some components are not picked from center also .. vacuum pickup i believe right?
22:43:47 <Ysjoelfir> no. they pick it up from the tape and place it at a specific coordinate. mostly done through image processing nowadays. they know where the parts are while looking at the pick and place data and the fiducials tell them where on the board the pnp machine is right now
22:43:53 <Ysjoelfir> yes
22:44:13 <Lemon> rust_collector interesting video indeed !
22:45:05 <hsn93> how does machine knows that (specific coordinate of pcb = center of the chip) ?
22:45:47 <hsn93> there is coordinate of footprint + coordinate of pcb .. i understand fuducials + image processing is for the pcb accuracy right?
22:46:15 <hsn93> but they also have to know that (4,4) in pcb = center of the footprint or somthing .. ?
22:46:31 <hsn93> (4,4) = (x,y) **
22:48:00 <hsn93> so i put center of component = pin 1 (in altium) then when i give them pick and place txt file .. it assumes that they know its pin 1 .. however sometimes i change it so that (x,y) is different
22:48:01 <Ysjoelfir> well, do they? they know where the center for the part is, this is where they pick it and place it at the specific position that the created pick and place data tells them
22:48:26 <Ysjoelfir> you shouldn't place the reference on pin one, that could give you errors ;)
22:48:33 <hsn93> fck !
22:48:53 <Ysjoelfir> at least when I learned it. maybe its different nowadays, idk
22:48:59 <hsn93> does this mean that all previous boards i sent where wrong ?
22:49:07 <hsn93> and someone edit them manualy?
22:49:42 <Ysjoelfir> no, not wrong. I'm pretty sure it's absolutey possible to have the reference not on center.
22:49:51 <Ysjoelfir> but how exactly they do it - no idea
22:50:07 <Ysjoelfir> i just use center references, that's pretty much foolproof
22:50:17 <hsn93> i checked the (pick and place txt file) before ..
22:50:17 <Ysjoelfir> and I don't see any advantage in using a reference somewhere else
22:50:35 <hsn93> its just components + coordinate in pcb ..
22:51:18 <hsn93> wait sorry
22:51:21 <hsn93> its much more data
22:52:36 <hsn93> Mid X Mid Y Ref X Ref Y Pad X Pad Y TB Rotation
22:52:52 <hsn93> assume ref x ref y = pcb coordinate
22:53:01 <hsn93> pad x pad y = i dont know what is it
22:53:54 <hsn93> mid x mid y = im not sure if its mid of component or origin i put
22:54:49 <hsn93> annyway, this is fine ? put origin != green cross-hair
22:56:04 <Lemon> https://www.ebay.fr/itm/EH-G710-PULSE-GENERATOR-50MHz-L284/293519253015?hash=item44571c5e17:g:WXoAAOSwyIledSCn I still kinda want it
22:56:07 <hsn93> i dont use center references because some times i need to set it manually to specific pin and put another pin according to that position ..
22:56:41 <hsn93> and doing center = center of pads and holes it doesnt consider 3d file or top overlay boundary box
22:57:02 <Ysjoelfir> I'm sure it is. the pnp will ignore the crosshair.
22:57:12 <Ysjoelfir> pad x and pad y is, i assume, the coordinate of pin 1?
22:57:44 <Ysjoelfir> you can set the reference to the center of the part automatically after you are done with the footprint. thats what I do
22:58:08 <hsn93> it works for chips
22:58:14 <hsn93> not connectors
22:58:24 <hsn93> right angle connectors for example
22:58:32 <Ysjoelfir> why would those be different?
22:58:40 <Ysjoelfir> and: do you pick and place them?
22:59:16 <hsn93> lol
23:00:39 <hsn93> this one for example: https://snipboard.io/uYomb0.jpg
23:00:44 <hsn93> center will be center of pads
23:01:05 <hsn93> but the center is way down .. ?
23:02:09 <Ysjoelfir> true
23:02:43 <hsn93> automatic center = center of pads
23:03:17 <hsn93> agh i think i shouldnt worry about this stuff
23:03:41 <Ysjoelfir> that is very true
23:03:53 <Ysjoelfir> i never did, it seeems to just work
23:04:01 <Lemon> hey Ysjoelfir, do you know the brand of the pulse gen I linked ?
23:04:02 <hsn93> cool thanks
23:04:44 <hsn93> do i've to worry about ipc2 ipc3 stuff? .. pad sizes nominal .. fillet ... etc?
23:05:06 <Lemon> and are those cables https://www.ebay.fr/itm/BNC-Male-Vers-BNC-Male-Cable-Coaxial-RG316-RF-50Ohm-Faible-Perte/352785874447?hash=item5223ad3e0f:g:TjkAAOSwroheZnzL correct to connect the generator to my scope ? I wanted short cables
23:05:35 <hsn93> or just put the pad little bit extra wide (0.3mm) or somthing it it will work
23:06:16 <hsn93> lemon i just bought somthing for this ^
23:07:20 <hsn93> https://www.aliexpress.com/item/32831271535.html?spm=a2g0s.9042311.0.0.29924c4dKw79PP
23:07:35 <hsn93> and sma cable
23:07:44 <Ysjoelfir> hsn93 - usually not. I tend to use the biggest pads per specification as I like to be able to hand solder stuff. so....
23:08:19 <Ysjoelfir> but if oyur employer wants you to get something realy dense, you may need to look into denser specifications - which could increase cost of manufacture. but that is dependant of your contractor
23:08:59 <Ysjoelfir> Lemon - no idea about that brand. regarding the cables: those look ok. I would make them myself.
23:09:21 <Lemon> ok thanks ! for the price, this pulse gen looks cool
23:09:25 <Lemon> I wanted one, for fun
23:11:26 * hsn93 pulses t3sl4
23:11:42 <hsn93> zap
23:11:59 <Lemon> I still really want an hp 3456a, the one on that surplus website was nice but idk, the website seems shady, items never sells, and they dont answer emails
23:12:18 <rust_collector> I think I am going to buy a few "important gear brand" stickers, and make boxes with many buttons and dials, and put them on ebay
23:12:28 <Lemon> I want two 6.5 digits dmm so I can dedicate one to 24/7 measurements
23:12:37 <Lemon> do that !
23:12:52 <K> dear lord, he is really turining into voltnut
23:13:12 <rust_collector> yes, he is lost. forget about this one
23:13:15 <K> right in front ov our eyes
23:13:23 <Lemon> ho not only voltnut sadly
23:13:27 <Lemon> time is interesting too...
23:13:32 <rust_collector> general nut
23:14:05 <Lemon> but yeah measurements, accuracy etc is really what is interesting me the most I think
23:14:17 <Lemon> I do love waveforms for some reasons, too
23:14:27 <Lemon> I have much fun with the siglent generator
23:14:33 <Ysjoelfir> to sum it up: Lemon is nuts :D
23:14:42 <Lemon> making weirdass waveforms on the computer, and sending it directly to the gen
23:14:47 <rust_collector> you do know you have to buy every damn device that exist, and average out the readings, right?
23:14:51 <Lemon> lemonuts !
23:15:42 <Lemon> yeah thats why I want to play with gpib, to make long term measurements and play with graphs
23:15:54 <Lemon> I do want to build a thermometer for the Vref
23:16:04 <Lemon> with those cheap sensors, that are accurate to 0.1C
23:17:44 <rust_collector> I still wonder what exactly you are going to measure, because buying a meter, to measure a second device, you bought to use to have something to measure with the meter, but you have to get a better meter, to make sure the device is good enough to be worth measuring with the meter, seems like a deep hole
23:18:10 <hsn93> https://hsn93.com/www/shaa-1.mp4 << T_T
23:19:02 <Ampera> Ysjoelfir, Lemon is the most mentally unstable person here
23:19:03 <Lemon> well honestly, I just like test equipement. you can call it a collection, or whatever, but what is nice is that each piece of gear I get teaches me new things, leads me to get other stuff etc ! thats what I really like, and about measurements I want to measure my 10v Vref, to see the drift, stability etc with temperature
23:19:14 <Ampera> and we have people who are close to genuinely criminally insane in here
23:19:16 <Lemon> unstable ? why that, because I like to get stuff ? :>
23:19:29 <Ampera> yer a packrat harry
23:19:52 <hsn93> no .. he ment u oscillate alot lemon
23:20:23 <Lemon> yeah true I like to go for one thing then another then another then back to the first etc
23:20:43 <hsn93> unstable :P
23:20:45 <Lemon> but im having fun, I feel good when I see my lil lab !
23:21:01 <rust_collector> yes, you do have some issues
23:21:02 <Lemon> ive made great deals, spent time to look for them etc
23:21:17 <Lemon> well I dont see that as an issue honestly
23:21:19 <hsn93> thats what the electrons say in an antenna when they reach to dead end .. lemon
23:21:25 <rust_collector> that is the issue
23:21:36 <Lemon> if having fun and learn is an issue... well
23:21:37 <Ampera> Don't worry Lemon, now that I have money, I find myself trying to get myself to stop spending it.
23:21:55 <rust_collector> haha. nah, have fun.
23:21:57 <Lemon> its hard !
23:22:00 <Ampera> Considering this fortnight I've bought a 200 dollar pair of headphones and pre-ordered a 200 dollar laptop I won't see until june at the best
23:22:02 <Ampera> I'm doing good so far
23:22:19 <Lemon> heh understandable
23:22:22 <Lemon> what is that laptop ?
23:22:26 <Ampera> Pinebook Pro

23:24:35 <rust_collector> ho ho ho
23:24:50 <Ampera> hsn93, it's running on my FreeBSD server about 5 feet to the right of me
23:24:57 Nick: hsn93 is now known as EEVb1og
23:25:00 <EEVb1og> hi.
23:25:02 <Ampera> Lemon, https://www.pine64.org/pinebook-pro/
23:25:15 <Ampera> I'll show the headphones I bought if anyone is interested in those too
23:25:18 <Lemon> im looking at it yeah, its interesting !
23:25:38 <Ampera> sweet they're out for delivery today
23:25:39 <Lemon> haaa headphones, I was into hi-fi gear a few years ago, gladly I managed to go out of that rabbit hole
23:25:41 <EEVb1og> ampera source code can i miss with it and push it back to u ?
23:25:54 Nick: EEVb1og is now known as hsn
23:25:57 * Ampera bans hsn
23:25:59 <Ampera> https://www.amazon.com/gp/product/B00SNI44CQ/
23:26:01 <Ampera> headphones
23:26:16 <Lemon> the best I ever got were fostex TH-900, with a ifi micro black label amp/dac
23:26:32 <Lemon> ha yeah momentum 2.0 are nice
23:26:33 <Ampera> I swear hsn I'll reprogram the bot right here right now to complain to you specifically whenever you fake its nick
23:26:38 <Ampera> ¯\_(ツ)_/¯
23:26:51 <Ampera> I have no clue if they're good or not, they are them germans brand and I like Ysjoelfir so
23:26:52 <hsn> i though u busy i wanted to put some useless features for fun ..
23:26:53 <Ampera> it all works out
23:26:55 <Lemon> I used the first version for a few
23:27:02 <Lemon> they are pretty light, comfy to wear
23:27:11 <Ampera> hsn, if you have features DM then to me
23:27:14 <Ampera> or PM me on the forums
23:27:16 <Ampera> or do something idk
23:27:23 <hsn> Ampera im actually a bot that u designed in future ..
23:27:31 <Ampera> if I had my email server running I'd put that here
23:27:38 <Ampera> hsn, is that why you're so annoying?
23:27:58 <rust_collector> useless features... did you get done designing the vacuum tube blinking led yet?
23:28:02 <Ampera> Lemon, my only concern was the active noise canceling A. can't be turned off B. is active, which sounds too good to have not been fucked up
23:28:05 <Ampera> even by sennheiser
23:28:13 <hsn> ampera, sorry if i annoy you. i'll tell this feedback to you in the future
23:28:26 * Ampera hugs hsn
23:28:28 <Ampera> everyone here annoys me
23:28:29 <Ampera> even me
23:28:52 <Lemon> ha I never really used noise cancelling
23:28:59 <Lemon> as I was listenning at home most of the time
23:29:10 <Lemon> outside I use some final audio f3000
23:29:13 <Lemon> or dunu falcon c's
23:29:24 <Lemon> I still have a lot of DAP's
23:29:27 <Lemon> I love those lil devices
23:29:35 <hsn> rusty, no :) vacuum tubes for legends not me
23:29:37 <Ampera> Well I have some Sennheiser GSP 300's on right now, and they sound as good as a hundred dollar pair of headphones + microphone can sound
23:29:41 <Lemon> the shanling m0 is a really nice, affordable and good sounding one
23:29:54 <Ampera> but they are about to disintegrate into shrapnel, so I really needed some new headphone
23:29:58 <Ampera> s
23:30:29 <Lemon> I see yeah
23:30:34 <Lemon> damn on the fostex I had
23:30:44 <Lemon> pads were so expensive... like, 100+ euros for one ?
23:30:55 <Lemon> but they were ultra comfy, made with vegetal leather or whatever
23:31:12 <Lemon> I was a bit sad when I sold it but well, I needed the money for other hobbies
23:31:20 <Ampera> lol this GSP's pads have fallen apart like a month or so after I bought them
23:31:29 <Ampera> just the cheap stitching's come undone
23:31:42 <Ampera> Sennheiser can make great shit but their pads are the first thing to go, and they do before their time
23:31:43 <Lemon> but I advice you to look for a little dac/amp, it really change your life
23:31:54 <Lemon> advise
23:32:21 <Ampera> the headphones have a DAC in them
23:32:55 <Ampera> but ideally I'd buy something like a focusrite scarlet. I have a Behringer 4 channel ADC/DAC in the other room for my DAW, and it's pretty alright
23:33:05 <Lemon> yeah I know, but its not a really good one, its decent at best
23:33:08 <Ampera> it's more there for digitizing instruments for DSP stuff
23:33:23 <Lemon> an adi-rme !
23:33:34 <Lemon> for real, if you can find a used ifi micro black label
23:33:37 <Ampera> Honestly 100 dollar Sennheisers on my onboard DAC sound perfectly fine to me
23:33:42 <Lemon> jump on it, they are really dope
23:33:49 <Ampera> so if that'll do, then anything'll do
23:34:00 <Lemon> what files are you using, 320kbps mp3 or lossless files ?
23:34:07 <Lemon> but yeah it sounds alright
23:34:12 <Ampera> I'm using 400-600kbps M4A's
23:34:18 <Lemon> nice !
23:34:24 <Ampera> YouTube rips :P
23:34:30 <Lemon> hehe
23:34:38 <Lemon> I had a nice 3tb lossless collection
23:34:41 <Ampera> but they're from the YouTube music library, so they're usually direct from album masters
23:35:12 <Ampera> This is what I'm listening to right now: https://www.youtube.com/watch?v=6LA0lKK4u18
23:35:24 <Ampera> I've been on a bit of a motown binge recently
23:35:58 <Lemon> groovy
23:36:04 <Lemon> well its time for a nap I think
23:36:09 <Ampera> have a good one, Lemon
23:36:12 <Ampera> I need to get to work :P
23:36:19 <Lemon> thanks ! see you in a few hours :>
23:36:24 <Lemon> courage !
23:36:27 <Ampera> ciao
23:36:30 <rust_collector> good to work
23:36:34 <rust_collector> good nap
23:36:40 <rust_collector> good... stuff
