01:26:05 <Ysjoelfir> hello all
01:26:15 <rust_collector> hello you
01:26:15 <EEVBlog> Hello there, rust_collector!
01:26:24 <rust_collector> and you
01:26:40 <Ampera> hi Ysjoelfir, how are you doing
01:26:56 <Ysjoelfir> hi rusty and Ampera
01:27:13 <Ysjoelfir> I'm having a bit of a blood pressure problem right bow, but besides that I'm rather fine, thanks :)
01:27:21 <Ampera> that sucks
01:27:25 <Ampera> hopefully you don't explode
01:27:33 <Ampera> or implode, whichever the problem
01:28:07 <rust_collector> hmm, just because I am curious, how do you notice?
01:30:15 <Ysjoelfir> exploding would be the case :D
01:30:47 <Ysjoelfir> I noticed because I felt dizzy and I can't focus on the things I'm looking at. it feels like my eyes are just a tad off focus
01:31:05 <rust_collector> hmm. ok
01:32:00 <Ysjoelfir> which is, as the doctor told me, because the higher blood pressure in the blood.......thingies of the eyes slightly deform it, so that the routine of "focus on that by adjusting this part of the eye by that much" isn't working with an offset
01:32:17 <Ysjoelfir> *is working, not isn't
01:32:30 <Ysjoelfir> also, I checked with a blood pressure measurement thingy
01:32:55 <rust_collector> yeah, but that is cheating
01:33:34 <rust_collector> the interesting thing, is to see what your body does.
01:43:54 <rust_collector> heh, I wonder why I have all these samsung phone chargers... I have never had a samsung phone.
01:49:03 Join: Lemon ([email protected]) to #EEVblog
02:01:25 <Lemon> im close to the 1M samples milestone
02:01:28 <Lemon> lets see how it goes
02:01:39 <rust_collector> BOOM!
02:01:49 <Lemon> im seeing paterns, like when my mother open the doors for cats in the morning, etc
02:02:36 <rust_collector> can you click the graph, and add text comments to that time?
02:03:02 <Lemon> no sadly I had to disable text boxes for performance
02:03:07 <Lemon> I can just zoom, which is fine already
02:05:09 <rust_collector> so, did you start connecting your devices to your intranet yet?
02:05:42 <Lemon> not yet no, I took a nap, im still fucking tired of yesterday's walk, im just chillin and looking at stuff and thangs
02:05:56 <Lemon> but idk if its a good idea to spend time setting it up on the workstation
02:06:03 <Lemon> as I want it on another machine
02:08:55 <Lemon> well I guess I could still install it on the main workstation
02:10:28 <rust_collector> at least it will have enough grunt do do whatever, so that is not something you have to think about, when you just want to get it working
02:11:09 <Lemon> thats true yes
02:11:14 <rust_collector> at least hook it up, and see if all the things can "talk" to it, I guess?
02:13:34 <rust_collector> hmm, as you have so many ancient devices.. are you going to run xp or something on that machine?
02:14:11 <Lemon> ho no win 10 will work I think, the usb/gpib interface I have got drivers for it
02:14:25 <rust_collector> oh well
02:14:26 <Lemon> if not well, I'll use a vm
02:14:36 <Lemon> and install the right os on the second machine
02:15:13 <rust_collector> I guess you like figuring out problems, lol, good luck
02:19:42 <Lemon> yeah im sure it will be a freaking pain
02:19:59 <rust_collector> no, it will work great
02:20:00 <Lemon> another problem is my tds 540, I realize its too far from the pc
02:20:11 <rust_collector> for a week
02:20:26 <Lemon> nah it will be more like, I'll spend a week to make it work then it will be fine
02:20:58 <rust_collector> well, you can believe that, if you want
02:21:04 <Lemon> I also need more gpib cables
02:21:31 <Lemon> well I have enough for now
02:21:38 <Lemon> but if I want to connect everything I need more
02:21:55 <rust_collector> meh, just try something, and see if it works at all
02:22:01 <Lemon> yeah
02:24:42 <Lemon> first I'll try to connect the 3456a and the 8502a dmms
02:25:58 <rust_collector> just do 2 things first, I think?
02:26:31 <rust_collector> i dunno, maybe it "just works" and you can just plug everything in
02:26:34 <Lemon> well you know it works by paralelling stuff
02:26:41 <Lemon> so I want to try that
02:26:54 <Lemon> like, pc to interface, interface to one dmm, cascading to the other
02:27:01 <Lemon> so I can figure how adresses etc works
02:27:19 <Lemon> just sending IDN to see if they responds
02:27:20 <rust_collector> ok, but if device 1 or 2 does not work at all...
02:27:28 <rust_collector> ok
02:27:44 <Lemon> ha yeah thats a possibility
02:28:59 <rust_collector> I mean, just try one and add one, then one...
02:32:19 <Lemon> yeah
02:32:25 <Lemon> first lets install drivers
02:47:13 <Lemon> alright 1.3gb for keysight IO suites
02:47:17 <Lemon> benchvue and shit
02:47:22 <Lemon> ima install everything
02:48:14 <rust_collector> heh
02:48:23 <Lemon> I like gpib cables
02:48:26 <Lemon> they are so bulky
02:48:38 <Lemon> you could lift the instrument with them connected without problems
02:48:51 <Lemon> its like those old ass paralell cables but on steroids
02:52:34 <Lemon> im kinda interested by labview home
02:52:42 <Lemon> it cost 50 euros or something like this
02:53:57 <rust_collector> does it have a free 30 hour test period?
02:54:10 <Lemon> hmmm I dont think so
02:54:16 <rust_collector> oh well
02:54:19 <Lemon> but its the full labview software, just for personnal use
02:54:20 <Lemon> which is neat
02:57:04 <Lemon> first I'll send some commands in talk only to see if the gpib works on my instruments
02:57:14 <Lemon> then I'll maybe get labview home, if reviews are that positive
02:57:34 <rust_collector> https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4553880/
03:00:04 <Lemon> interesting
03:00:08 <Lemon> theres so many possibilities
03:00:50 <rust_collector> yep
03:00:59 <rust_collector> and I know nothing about oll of them
03:01:04 <Lemon> the hardest but not that useful anyway, will be the e-load
03:01:12 <Lemon> it uses rs-232 and rs-4whatever
03:01:18 <Lemon> but nothing is documented
03:01:22 <rust_collector> 488?
03:01:43 <Lemon> 452 I think
03:01:46 <rust_collector> ok
03:01:49 <Lemon> IEEE 488 is gpib
03:01:52 <rust_collector> oh, yes
03:02:04 <rust_collector> rs.... ok
03:02:35 <rust_collector> that is the next thing then
03:02:40 <Lemon> and theres the gpsdo too that I havent figured
03:03:26 <Lemon> https://www.ebay.fr/itm/AMPHENOL-GPIB-CABLE-2-0-METERS/283852495069?hash=item4216ed58dd:g:m8QAAOSwNBlem~IF
03:03:34 <Lemon> hmm that could do the trick for the scope that is far
03:03:39 <Lemon> I could move it a bit but not much
03:05:59 <Ysjoelfir> [17:32:57] <rust_collector> yeah, but that is cheating
03:05:59 <Ysjoelfir> [17:33:36] the interesting thing, is to see what your body does.
03:06:16 <rust_collector> well. you know
03:06:21 <Ysjoelfir> Thats true. and I "enjoy" discovering that some of the things I noticed before seem to be correlating with the pressure
03:06:47 <rust_collector> everything is connected
03:09:35 <Lemon> https://www.ebay.fr/itm/Lenovo-ThinkPad-X220-intel-i5-2-5GHz-4GB-160-HDD-12-5-WLAN-W10-2041/233561257505?hash=item366155f621:g:TycAAOSwkeFemELq
03:09:43 <Lemon> im tempted by this one
03:09:53 <Lemon> it comes without battery, which is most of the time close to be dead anyway
03:10:04 <Lemon> it looks in good state
03:10:13 <Lemon> a little ssd and bam its a quick little machine
03:10:32 <Lemon> it got the i5, 4gb ram is fine for what I want to do, anyway its cheap if needed
03:11:50 <rust_collector> yes, I am not sure if those can take a second drive? a spinner for storing your jun...I mean logs would work
03:12:10 <Lemon> ho well, logs dont take much anyway
03:12:14 <Lemon> and I think they can
03:12:18 <Lemon> if you remove the cd drive
03:12:22 <rust_collector> right
03:12:35 <rust_collector> I just did not bother looking if it has a cd drive
03:13:52 <Lemon> a brand new battery sold in france cost 25 delivered, so well
03:14:01 <Ampera> explosions
03:15:12 <rust_collector> log to cd, just to be weird
03:23:17 Join: hsn ([email protected]) to #EEVblog
03:24:29 <Ysjoelfir> explosions sounds great!
03:35:58 <hsn> only when its small
03:36:22 <rust_collector> oh, big explosions sounds great too
03:36:44 <hsn> not chernobyl explosion or somthing similar
03:36:58 <rust_collector> did you hear that?
03:37:21 <hsn> i saw video
03:37:35 <rust_collector> yes, but we are talking about the sound
03:37:57 <rust_collector> I do prefer slow explosions.
03:37:58 <hsn> i heared
03:43:34 <rust_collector> ok. well, I didn't know they were filming that. But anyway, you are wrong, it sounds great, lol
03:49:47 <Ampera> Good god, everything's broken at work and IT's gone and fucked off
03:51:18 <Ysjoelfir> seriously? XD
03:51:48 <rust_collector> ok, now.. did mt IT get paid this month?
03:52:50 <rust_collector> maybe he is up on the roof, adjusting the antenna. you never know what IT guy is doing, to keep things working for you
03:53:05 <rust_collector> could also be on his way to mexico
03:53:08 <Ampera> Ysjoelfir, the one guy who's responsible for dealing with testing environment issues is AWOL on teams
03:53:21 <Ampera> other guy who does IT that I know of is also AWOL
03:53:54 <Ysjoelfir> that sounds simmilar to what is happening at my work. our buying departmenr is like "since you forced us to use that shit piece of software everything is going haywire! I'm not going to do shit until you allow me tu use the old method!"
03:54:25 <Ysjoelfir> which is more like AWL instead of AWOL, but hey. close enough
03:55:05 <Ampera> What sucks is I have four weeks to do a complete and total round of tests on this mobile app
03:55:12 <Ampera> oh, and it doesn't have any tests to speak of
03:55:22 <Ampera> so I just need to bumble through it and keep trying to break shit
03:55:24 <Ampera> OH GOODY
03:55:58 <Ysjoelfir> yay
03:59:57 <rust_collector> Now that I have 2 weeks off, I hope work blows up slightly.
04:00:59 <Ysjoelfir> heh. nice
04:01:59 <Ysjoelfir> I will be going to the doctors tomorrow and listen what she has to tell me about my blood pressure. maybe I'll be having off the next two days, too.
04:02:04 <Lemon> ok so I installed the keysight suite
04:02:15 <Lemon> it seems I can communicate with the 3456a
04:03:09 <Lemon> -> *IDN?
04:03:09 <Lemon> <- /:>.>:;;;O+:?x0F?
04:03:22 <Lemon> whatever it means
04:03:42 <Lemon> if I hit device clear it removes some configs
04:03:47 <Ysjoelfir> Sounds like ">.> what the 0+:?x0F? do you want!?"
04:03:56 <Lemon> yeah lol
04:04:00 <Lemon> they are on talk only
04:04:11 <Lemon> that means I can just talk to them right ?
04:04:16 <Lemon> they cant send stuff back ?
04:04:21 <Lemon> or the opposite maybe
04:06:32 <Lemon> Ysjoelfir can I remove the gpib/usb interface to change the device while they are on ?
04:06:37 <Lemon> or should I turn them off
04:07:09 <Ysjoelfir> hmm... IIRC GPIB is not hotpluggable.
04:07:33 <Lemon> ok lets turn them off then
04:09:49 <rust_collector> time to fire up the grill
04:10:17 <rust_collector> I made a salad. it is full of vegetable sort of things
04:19:56 <T3sl4> GPIB is just a momentary bus, devices don't even realize it's connected until some signals are asserted
04:20:06 <T3sl4> it's hotpluggable :P
04:21:17 <Lemon> right now, I have the agilent usb/gpib connected on the fluke, which is itself connected to the hp 3456a
04:21:24 <Lemon> I see two devices, which is a good sign
04:22:25 <Lemon> -> *IDN?
04:22:25 <Lemon> <- +0.339359E+0 at first he told me that
04:22:37 <Lemon> with idn he read whats was on display for some reasons
04:23:56 <Lemon> hmmm but I cant communicate with the fluke
04:26:04 <Lemon> the fluke seems to freeze when I scan devices
04:36:20 <Lemon> ok so its not seeing the fluke
04:37:02 <rust_collector> try a different cable?
04:37:16 <Lemon> its not the cable, I tried directly with the gpib/usb cable
04:42:36 <rust_collector> is the fuse ok?
04:43:34 <Lemon> yes, I mean the fluke works
04:43:40 <Lemon> I just cant communicate with it
04:43:47 <rust_collector> the gpbfkg fuse
04:43:58 <Lemon> but theres no fuse in it, its a cable
04:44:11 <rust_collector> inside the fluke?
04:44:12 <rust_collector> ok
04:47:17 <rust_collector> i have to put together a toolbox to keep in the car. It is already full of tools and stuff everywhere.
04:57:44 <Lemon> heh thats neat
04:57:56 <Lemon> ok so I sent idn to the fluke, and it restarted the dmm
04:58:03 <Lemon> thats something
04:58:50 <rust_collector> what model frooke was this?
04:58:57 <Lemon> a 8502a
05:00:14 <Lemon> hmm I tried another command, and it returned me some shit, also froze the dmm
05:00:28 <Lemon> so I guess its just a communication error, no hardware problem with the fluke itself
05:02:19 <Lemon> HA !
05:02:22 <Lemon> I tried a random shot
05:02:33 <Lemon> MEAS:VOLT:DC? and it outputed me something right
05:02:40 <Lemon> +0.002568E+0
05:02:46 <Lemon> nothing is connected so it works
05:08:12 <rust_collector> aah yes, new boris video
05:08:14 <Lemon> ok it works
05:08:21 <Lemon> sent 5v from a psu
05:08:27 <Lemon> -> MEAS:VOLT:DC?
05:08:27 <Lemon> <- +05.09724E+0
05:08:33 <Lemon> its just not detected by benchvue
05:19:34 <Lemon> ok the 5345a seems to work too but idk what to do with it, its a bit too complicated yet
05:19:38 <Lemon> but the 'RMT' led shows up
05:19:41 <Lemon> so it communicate
05:26:27 <rust_collector> Ysjoelfir, you like a bit of retro things, right?
05:26:34 <rust_collector> https://www.finn.no/bap/forsale/ad.html?finnkode=167966283
05:32:00 <Lemon> well seems that the three devices gpib work, now I have to figure how to use them
05:32:13 <Lemon> the 3456a seems to be the easiest one, being common

08:15:33 <DougR> I have really enjoyed watching a bunch of your videos. Most recently; EEVblog #594 - How To Measure Power Supply Ripple & Noise. And I think you are probably the right guy to ask. I am looking for the proper way to view/measure ripple & noise on industrial DC power supplies for the electroplating industry. The larger units are 15vdc / 5000amp,
08:15:33 <DougR> And I am wondering if I should be using two channels and math function as you describe in the video. Might you have any thoughts or direction to offer. To compound issues, I am trying to do this remotely/virtually with my customer due to pandemic. They have a Hantek DSO1202E unit (which I have never used before). I am fairly sure I could stumbl
08:15:33 <DougR> e my way through if I was live but they are still not allowing visitors. I am hoping to talk their maintenance guy through testing for us. Sorry this was so long!
08:17:09 <rust_collector> DougR, I guess I should tell you that dave does not really use irc, as far as I know.
08:17:51 <rust_collector> there are some other people here, who might know things...

08:21:51 <Halcyon_Work> Oooer :P
08:21:54 <Halcyon_Work> I'm on my new laptop
08:22:37 <rust_collector> it looks like you grabbed a laptop at work?
08:23:47 <Halcyon_Work> Yeh the one I ordered arrived yesterday
08:25:29 <rust_collector> what izzit?
08:25:42 <Halcyon_Work> ThinkPad P1
08:26:57 <DougR> I'm open to any suggestions. I have reached out to the power supply manufacturers (DynaPower, Kraftpower), but they have not been very helpful.
08:32:47 <rust_collector> DougR, if you hang around, I hope someone will have an answer for you. i have no idea.
08:33:18 <rust_collector> Halcyon_Work, is it a good sign when lenovo says: This product is no longer available. ??
08:33:23 <rust_collector> looks nice
08:37:08 <Halcyon_Work> rust_collector, that's probably the Gen 1, the Gen 2 came out not long ago
08:37:27 <rust_collector> yeah, I assumed that
08:38:25 <rust_collector> should be good enough to run both the irc client, and solitaire with all the colours enabled
08:39:36 <Halcyon_Work> Hehe it'll run games better than my desktop
08:39:42 <Halcyon_Work> In 4K too
08:43:10 <rust_collector> we can not have that... when does your new desktop come?
08:43:46 <Halcyon_Work> I'm not getting a new desktop
08:43:53 <Halcyon_Work> My laptop will replace my desktop
08:44:51 <rust_collector> but, it is just a laptop... you can not do that
08:45:36 <Halcyon_Work> Hehe
08:45:57 <Halcyon_Work> Might as well have the best of both worlds, I need the portability as well
08:46:57 <rust_collector> hmm, does that thing have a 4g or 5g modem thing?
08:47:15 <Halcyon_Work> Nah, I just tether to my phone
08:47:19 <rust_collector> ok
08:47:21 <Halcyon_Work> I don't want to order a second SIM/service
08:48:08 <rust_collector> I have a second sim, but I do not think my modem support 4g, so...I am just interested in what the never things use

19:06:21 <Lemon> hello bois
19:24:14 <hsn> hello there, Lemon!
19:24:53 <Lemon> hello hello hello
19:25:13 <Lemon> I just received some 10mm leds, they are funny
19:25:32 <hsn> so u are laughing while looking at them ?
19:25:58 <hsn> :P
19:26:09 <Lemon> exactly
19:31:05 <Lemon> so it seems my data loggers starts to lag after 1M samples
19:32:50 <hsn> u mean the vb.net program ?
19:32:55 <Lemon> yeah
19:33:00 <Lemon> its not optimized for that
19:33:05 <hsn> how r u logging it
19:33:12 <hsn> sqlite?
19:33:20 <Lemon> drawing a ms chart with serial data from an arduino
19:33:33 <hsn> :>
19:34:47 <hsn> u can store them .. and for graphing u do interpolation ?
19:37:03 <Lemon> im using the built in ms chart feature
19:37:29 <hsn> i dont knw how octave or matlab plot with lots of samples .. but i used python with some plot library i dont like to go more then 2048 samples in screen .. so i used to shift with time
19:38:00 <hsn> hmm but u give it array of samples and u can play with no ?
19:39:25 <hsn> actually check this
19:39:26 <hsn> https://stackoverflow.com/questions/27339553/improving-the-performance-of-drawing-a-huge-number-of-points-with-help-of-mschar
19:39:28 <Lemon> I dont have much knowledge honestly, I played with some examples I found around and optimized it as much as I could, I can zoom on the graph which is a nice thing, I wanted to have 3.75 samples a second (thats the output from the adc)
19:39:45 <Lemon> yeah I bet they tell to use fastlines
19:40:02 <hsn> that thing i think puts horizontal scroll
19:40:06 <hsn> on the points
19:44:46 <Lemon> I thought about a scroller yeah
19:44:49 <Lemon> I'lltry that thanks
19:44:57 <hsn> np
19:45:01 <Lemon> but well I think its not made for what im doing anyway
19:45:04 <hsn> so u store them in file as wll
19:45:30 <hsn> so in case program is closed u dont lose the data
19:45:46 <hsn> ?
19:50:28 <K> hello
19:50:29 <EEVBlog> Hello there, K!
19:53:01 <Lemon> I wanted to, but it lags after 1k samples lol
19:55:31 <Lemon> but yeah it takes like 324k samples a day
19:55:50 <Lemon> I should rewrite it in another language, I simply have no knowledge and I spent days on this one already
19:57:47 <hsn> lemon use "sqlite" u will like it
19:58:15 <Lemon> I saw that most peeps use java to do this
19:58:28 <hsn> hllo there, K!
19:59:00 <hsn> u can do it with vb.net the language is not issue
19:59:35 <hsn> https://www.codeproject.com/Articles/1210189/Using-SQLite-in-Csharp-VB-Net ^
20:00:41 <hsn> u can also use normal file io .. but r u over writing or u seek position and writing new data ?
20:01:20 <Lemon> the arduino outputs data like : first line 22.24 second line 22.25 etc
20:01:33 <Lemon> im reading that and write it
20:01:39 <Lemon> after the last one I wrote
20:02:18 <hsn> so how does the code look like ..
20:02:36 <hsn> open file.txt for write ... seek last position .. write new data close file ?
20:03:25 <Lemon> theres no txt file, its more like data = serialread, ms chart blabla add newpoint(data) etc
20:04:36 <hsn> <Lemon> I wanted to, but it lags after 1k samples lol <<<<--------- what u were refering to here
20:04:45 <hsn> plotting or logging
20:04:56 <Lemon> ho I tried to write in an excel file to implement a save/loading feature
20:05:06 <Lemon> but it was freezing with 1k samples when saving
20:05:09 <Lemon> so I just forgot about it
20:05:18 <hsn> ah ok so ur doing it directly from mschart
20:05:30 <Lemon> yeah over serial
20:05:43 <hsn> like mschart.export(excelformat, "filepath")
20:07:00 <hsn> try file.txt
20:07:29 <Lemon> hmm no I was writing at the same time each data points
20:07:34 <Lemon> maybe I should try that instead
20:07:36 <hsn> IO.File.AppendAllText("C:\Log.txt", String.Format("{0}[{1}]{2}", data.time , data.temperature, etc)
20:09:22 <hsn> although i think u should save every 2k samples or somthing ..
20:10:07 <Lemon> im going to try that after meal :>
20:10:13 <Lemon> brb in a few dude
20:11:06 <hsn> enjoy

20:13:44 <canadaguest> morning hi as usual
20:14:43 <canadaguest> any of you know what other terms I could try use beside just 'ebook' to find full electronic articles to be able to read online?
20:17:34 <K> what are you looking for?
20:18:28 Join: Halcyon_ ([email protected]) to #EEVblog
20:18:32 * Halcyon_ mews at the rooms
20:18:34 <Halcyon_> *room
20:19:07 <K> "cats who meow at roms", a movie
20:19:25 <Halcyon_> :P
20:21:31 <K> canadaguest: have a look here - http://libgen.is/
20:33:07 <canadaguest> k k thanks thats a nice source. and I was just looking for something that was a lot better than just "heres a schematic and heres how the capacitor looks like on graph" 1-page websites which of course doesn't really help with the core problem :-s
20:33:19 <Lemon> hello canadaguest
20:33:22 <Lemon> im back hsn
20:33:26 <canadaguest> I'm looking for anything to do with rectifier, dc filter, etc. basically anything relevant toward that category
20:34:06 <K> um, have a look at AoE book? i think the section about linear power supplies was available as a free preview
20:38:38 <K> hm, mayhbe i am wrong about that
20:48:26 <canadaguest> k its ok I was a bit busy looking at that libgen source. found some more things to hopefully help notes-wise later on :)
20:49:37 <Lemon> I wonder how hard would it be to build a multi channel voltmeter, accurate to mv at least
20:49:51 <Lemon> no need for fancy features it would be to monitor power supplies
20:50:01 <K> build many single channel ones
20:50:24 <Lemon> yeah
20:50:48 <Lemon> a Vref, adc's and what else, opamps I guess ?
20:50:53 <Lemon> with a uC ofc
20:51:31 <canadaguest> k I guess one of my few small issues atm was how to choose the inductor if at all. so yeah the new notes seem like it'll finally come to a conclude :)
20:53:22 <Lemon> have you build yourself a little lab canadaguest ? :>
20:55:24 <canadaguest> lemon no
20:55:46 <Lemon> by that I meant getting some second hand psu/scope/dmm, so you can work well
20:55:58 <Lemon> its quite nice to have access to high end gear for cheap
20:56:05 <Halcyon_> Hey Lemon :)
20:56:12 <Lemon> hey ! whats crackin ?
20:56:38 <Halcyon_> Not much
20:56:42 <Halcyon_> How about you?
20:57:11 <canadaguest> lemon heh actually as soon as I can figure out the circuit to build I was going order a few tools to keep with the train table itself. and that includes a few hand&electronic tools from weidmuller
20:57:16 <Lemon> hmm same, saw my best friend yesterday, we walked for a good 3 hours :> I havent seen her since the lockdown
20:57:32 <canadaguest> especially a specific multimeter that can do with measuring ac frequency
20:57:52 <Lemon> good idea, a knippex cutter/needle nose plier is also a must have
20:58:08 <Lemon> but trust me look at second hand stuff !
20:58:14 <Lemon> the perf/price is unbeatable
20:58:43 <Lemon> for example I received a metrix 50v/2a lab supply I paid 34 euros with shipping recently
20:59:29 <Lemon> also 185 euros for a 6.5 digit dmm that is probably more accurate than some 800-1000 euros new ones
20:59:34 <Lemon> if not more
21:00:47 <Lemon> a fluke ac clamp for 30 delivered too, but im still waiting for it
21:00:52 <Lemon> good deals to be made !
21:01:22 <canadaguest> lemon well tbh I'm not so sure if theres ever much second-hand market around here for the things I in particular wanted. but thanks for the thoughts still :)
21:01:35 <Lemon> ebay dude !
21:01:45 <Lemon> or a local website, just find peeps that can send stuff
21:01:52 <Lemon> I only bought something once in person :>
21:02:03 <Lemon> a nice tektronix tds 540, drove 600km to get it xD
21:02:13 <Lemon> but it was a neat deal and the dude was really nice
21:02:20 <hsn> hey my stomach is generating roar sounds
21:03:02 <Lemon> heh !
21:03:09 <Lemon> btw hsn do you have visual studio installed right now ?
21:03:16 * steve30 meows at Halcyon_
21:03:22 <hsn> yeah but not vb.net
21:03:25 <hsn> only c#
21:03:29 <Lemon> ha ok
21:03:48 <hsn> let me check how much it takes to download
21:04:41 <Lemon> because I can send you the program I made, you just need a random arduino outputing random serial values to test it
21:05:24 <canadaguest> lemon well 600km would invoke more forests and not much else so...sorry? :P
21:05:29 <Lemon> I found someone selling a 4m gpib cable for 30 euros
21:05:54 <Lemon> haha no but its an example, 99% of my lab was bought with delivery :P
21:06:13 <Lemon> I often see good deals on ebay coming from canada
21:07:16 <hsn> i used oxyplot lemon
21:07:37 <hsn> but i plot few points
21:08:29 <Lemon> if I could find a way to save every 24h or so without making shit lag, that would be nice
21:08:40 <Lemon> also a way to load graphs
21:10:01 <hsn> send it to me
21:10:17 <Lemon> ok sec
21:10:25 <hsn> i ll check it for u .. im not great programmer but i might help
21:11:44 <Lemon> https://easyupload.io/2bkden thanks bud thats nice !
21:11:53 <Lemon> I used a random upload thingie
21:11:56 <Lemon> it should work

21:15:52 <Lemon> canadaguest ho also, get a good desk lamp ! theres a nice one on banggood for 20 euros, you can turn it in whatever way which is pretty useful
21:16:19 <canadaguest> don't need one :)
21:16:43 <Lemon> alright :> and as a soldering iron, the ts100 is really good, especially for its price
21:24:29 <hsn> lemon , what is this ( If (LDR_1 - LDR_1Log) > -10 And (LDR_1 - LDR_1Log) < 10 Then
21:24:29 <hsn> LDR_1Log = LDR_1
21:24:29 <hsn> End If)
21:28:42 <Ampera> good morning
21:29:57 <canadaguest> lemon a solder gun at least is somewhat commonplace so as long as I still can find new tips (service parts that is or whatever you people call them) for them so there
21:30:26 <K> solder gun?
21:38:48 <Lemon> excuse me a random cat showed up with her guts out of her vagina....
21:39:19 <Lemon> hsn ha it was to remove those random peaks, because it was losing chars but its not necessary anymore I think
21:39:34 <hsn> ok
21:39:39 <Lemon> canadaguest I do want a nice electrical solder gun too
21:39:40 <canadaguest> k yeah I kinda prefer them due to rating and re easy localized on/off switch
21:39:43 <Lemon> but damn the cat
21:39:59 <Lemon> im on the verge of throwing up

21:43:10 <Ysjoelfir> Damn router.
21:44:06 <canadaguest> oh that reminds me why do many companies sell soldering wires only in weight .. like I mean just how many meters is "10oz" at all anyway?
21:44:15 <canadaguest> maybe I'm not understanding why they sell it that way :->
21:44:41 <Lemon> isnt it the weight of copper per meter ?
21:45:16 <Ysjoelfir> well, would you have particularely more information when its in length? like, would it tell you better how long it will last?
21:45:19 <Ampera> Lemon, well that was a brilliant start to my morning :P
21:45:44 <Lemon> heh Ampera and im watching a speedrun of doom 2016, what a coincidence
21:46:24 <Ampera> Always remember, nature has no chill.
21:48:00 <Ampera> I think I might have some prosciutto for breakfast
21:48:18 <canadaguest> ysjoe I want more than 2m?
21:48:46 <Ysjoelfir> well... that may be the case, but why is it important that you have more than 2 meters instead of more than 50 grams?
21:49:33 <Lemon> well I think its more interesting to know how long the spool of wire is
21:49:49 <Lemon> like you know approximatively what you have if you buy 10 meters of wire
21:49:50 <Ampera> My dad's sauerkraut has finished fermenting
21:49:54 <Lemon> the weight, not so much
21:50:41 <canadaguest> ysjoe 50 grams of what?
21:51:34 <canadaguest> lemon yeah I'm not worried about exact lengths knowing that theres always some wastes/offcuts but nothing like eg coming a bit past halfway into the project then find your spool is empty of all the **** thing :)
21:51:35 <Ysjoelfir> solder
21:52:05 <Lemon> yeah I also prefer to know the lengh of what im buying
21:52:13 <Ysjoelfir> empty solder? won't happen to me :D
21:52:20 * Ysjoelfir stores around 5 kg of solder...
21:52:23 <Lemon> I think he talks about cables :>
21:52:25 <Lemon> not solder
21:52:29 <Ysjoelfir> oh
21:52:32 <canadaguest> lemon as I would say "better to have just about or too much, than end up with too little"
21:52:36 <Ysjoelfir> then ignore my mumbling
21:53:26 <canadaguest> ysjoe maybe you were thinking of solder *paste* which for certain can't be measured in lengths :)
21:53:51 <Ysjoelfir> no, I was thinking about solder. the silver wire, mostly made from tin, you put onto the tip of your soldering iron^^
21:54:17 <Lemon> ha yeah weight make sense
21:56:08 <canadaguest> ysjoe heres a nice math question for you perhaps: roughly how many 12mm solders is a 10oz spool good for? :)
21:56:14 <canadaguest> hehe
21:56:45 <Ysjoelfir> what is a 12mm solder? and how much is 10oz in a reasonable unit?
21:57:21 <Ampera> Did I just catch the Canadian doing an American? >:D
21:57:30 <Ampera> 10oz is 10oz in a reasonable unit.
21:58:09 <canadaguest> ampera but how many lengths is that tho?
21:58:26 <Ampera> depends on the makeup of the solder and the gauge
21:58:51 <Ampera> but in general, find the rough weight of the components involved including the tin/lead mix and the flux core (if it has one), and then calculate by volume
21:59:02 <Ampera> if you have specifications for max/min gauge across the length even better
21:59:53 <Ysjoelfir> oh, its just 283.495 grams. I would say that lasts for my useage around five months. since I don't keep statistics about how many solder points of a specific size I make I can't calculate number of joints
22:01:27 * Ampera passes a joint around
22:04:24 <Ysjoelfir> I asume I would die if I smoke that
22:05:43 <canadaguest> ysjoe well this is more liek 1 week not 5 months but np anyhow
22:06:04 <Ysjoelfir> I assume you solder way bigger stuff than I do then
22:06:20 <canadaguest> 20awg wire with many contacts? :)
22:06:59 <Lemon> im still using one of my fathers spool, he used it maybe 2 years and it feels like its almost new
22:08:06 <Lemon> ho also Ysjoelfir, I managed to communicate a bit with the fluke, hp and hp counter ! now its a matter of using them properly
22:08:14 <Lemon> IDN? is just reading the outputs
22:08:17 <Lemon> thats werid
22:08:19 <Lemon> weird
22:08:23 <Ysjoelfir> what is 20AWG now supposed to be again? :D
22:08:42 <hsn> slightly bigger 0.5mm^2
22:09:09 <Ysjoelfir> oh ok. thats not that big actually
22:09:19 <Lemon> im using 28awg I think
22:09:26 <Lemon> + random bigger ones I salvaged when needed
22:09:28 <Ysjoelfir> and that is...?
22:09:35 <hsn> 28awg is very tiny
22:09:38 <Lemon> small af ? xD
22:09:46 <hsn> like close to enambled wires
22:09:48 <hsn> for cores
22:09:51 <Lemon> I have no idea im not using awg either, I just read whats on the label :>
22:09:56 <Lemon> wrapping wire yeah
22:10:17 <hsn> 0.08 mm^2
22:11:04 <canadaguest> lemon heh well just for to do some initial test circuits on dummy loads here atm I have this donated 1.8m spool although I'll probably eventually going to have to stop any further pre-traintable tests as theres about less than 20cm left
22:11:13 <Ysjoelfir> that is like the core of my microphone wire. I use it for patching circuits/prototyping, .5mm² for breadboarding and 1 to 2.5mm² for higher current stuff.
22:11:42 <canadaguest> not sure if I'll ask about another unused spool somewhere else or just order the for-project spool early on
22:11:48 <Ysjoelfir> *.25mm²
22:13:05 <rust_collector> hey allthepeople
22:13:16 <K> Ysjoelfir, have you ever tried the thin ussr made teflon wire for prototyping?
22:13:49 <Ysjoelfir> No, I don't have any. I love soviet stuff, so I would love to try it. Do you have a source?
22:13:52 <Ysjoelfir> hi rusty
22:13:58 <canadaguest> mm well I'm not really that curious yet but does the presence of halogen in solder wires actually matter for some people?
22:14:38 <K> https://www.ebay.com/itm/0-12mm2-26AWG-ex-USSR-Copper-Teflon-PTFE-Wire-MGTF-QTY-20m-66ft/262805942724?hash=item3d307471c4:g:RB8AAOSw8PJb8dxn
22:14:57 <K> something like this
22:15:17 <Ysjoelfir> I HATE halogen free cables.they always have a like... powdery, smeary surface feeling that I hate as fuck
22:15:45 <Ysjoelfir> that is sweet, I may try that.
22:16:26 <K> it is quite nice
22:16:28 <canadaguest> ysjoe well my question more was to peopel that did not want halogen. I was kinda curious why :)
22:16:44 <Ysjoelfir> It's pretty hard for me to find stuff from eastern countries in german ebay. they have such nice stuff.....
22:16:51 <canadaguest> you do make me wonder if the powder you're talking about is from a chemical used to replace halogen with tho
22:16:56 <Ysjoelfir> canadaguest - ok, IÄ'm silent now :P
22:16:58 <Ysjoelfir> I think so
22:17:03 <rust_collector> Ysjoelfir, stop using ebad.de?
22:17:10 <K> ebad heh
22:17:14 <Ysjoelfir> how?
22:17:26 <canadaguest> ysjoe one thing I don't mind from you tho. any comment on leaded vs leadfree?
22:17:39 <rust_collector> use .com, or...
22:17:44 <K> or .co.uk
22:17:51 <rust_collector> no, not that one
22:18:00 <K> sometimes it has stuff .com wont show
22:18:02 <Ysjoelfir> canadaguest - I use both, depending on the application.
22:18:14 Quit: PsySc0rpi0n ([email protected]) Ping timeout: 121 seconds
22:18:17 <Ysjoelfir> K - true, but those usually don't ship to germany, sadly :(
22:18:45 <K> eh, i've asked nicely and they've shipped to my potato land as well
22:18:49 <Ysjoelfir> I was searching on .co.uk for food flavouring a while back. found so many, but none shipped here
22:18:59 <Ysjoelfir> hmm... ok
22:19:03 <Ysjoelfir> I could try that
22:19:06 <Ysjoelfir> but I'm shy :P
22:19:11 <K> they cant hit you in the face over the internet
22:19:17 <Ysjoelfir> hehe
22:19:49 <canadaguest> ysjoe mm I kinda like leadfree personally but then again I often work in non-workshop conditions especially small space with no artificial airflow so yeah not getting too many whiffs of lead in my face
22:20:23 <Ysjoelfir> I use an extractor, so that is no problem to me
22:21:01 <Ysjoelfir> I use leaded for old stuff that uses lead in the first place and lead free for most of my prototyping
22:21:13 <canadaguest> well I'm not in one spot but to our own purposes after all :)
22:21:17 <rust_collector> I can not say getting a whiff of lead is a big problem anyway.
22:21:25 <canadaguest> heh actually I still use leadfree even on the 80 year old breadboards but :->
22:21:35 <canadaguest> rust_collector but several times per day?
22:21:41 <rust_collector> nah
22:21:45 <K> if you don't soleder every day all day, doubt it does you much worse than walkin in a busy traffic (on a sidewalk)
22:21:55 <canadaguest> well lead being lead I'll prefer to do without the health problems from it tbh
22:21:56 <canadaguest> but :)
22:22:14 <K> lead does not vaporize when soldering
22:22:29 <K> if you dont actually lick the solderwire, it has no way to get inside you
22:22:36 <canadaguest> k heh do I have to mention I'm a non-city person
22:22:36 <rust_collector> there is probably other chemicals in that "smoke" that is worse than the lead.
22:22:45 <Ysjoelfir> [14:22:58] <K> lead does not vaporize when soldering
22:22:46 <Ysjoelfir> [14:23:13] if you dont actually lick the solderwire, it has no way to get inside you
22:22:48 <K> yea, fluxes are more of a hazard
22:22:55 * Ysjoelfir sometimes holds his solder in his teeth
22:23:05 <K> welp.
22:23:14 <rust_collector> now he is high all the time
22:23:51 <Ysjoelfir> actually I'm down. got a blood pressure medication I have to take now
22:23:53 <K> problem with lead is that it gets into landfills and then into groundwatter
22:24:09 <canadaguest> k well I know its not quite related but why did they ban leaded gasoline even although its still of the simialr octane type used in unleaded gasoline?
22:24:25 <K> i dunno about that chemistry
22:25:07 <rust_collector> probably hte same, it gets in the water and stuff. I don't know why polytics do anything
22:25:18 <K> but i suspect higher temeperatures, weaker chemical bonds in organic stuff
22:27:07 <hsn> lemon
22:27:21 <hsn> how many data the thing become laggy?
22:28:35 <rust_collector> because they can
22:28:41 <rust_collector> I blame the eu
22:31:11 <canadaguest> lemon anyway if I maybe ever think about it I might have a photo of the toolbox when II start on my project and you can see what kind of tools I end up buying ok? :)

22:33:37 * canadaguest will go off for now tho especially with being out later too
22:33:45 Part: canadaguest ([email protected]) from #EEVblog
22:34:03 <rust_collector> great. day 2 of my vacation, and boss is calling, lol
22:35:01 <hsn> he miss u
22:35:09 <rust_collector> yes, probably
22:36:03 <Ysjoelfir> I heard yopur phone is off
22:36:24 <rust_collector> how could you hear that?
22:36:30 <Ysjoelfir> you told me
22:36:43 <rust_collector> well, i will call himback some time
22:38:04 <Ysjoelfir> what on earth is that https://www.ebay.com/itm/Vintage-ex-USSR-chip-K145IP8-QTY-1/261824007207?hash=item3cf5ed4c27:g:ni4AAOSw34FVEllH
22:41:32 <rust_collector> robot spider for surgery
22:41:37 <K> ic with an ceramic package
22:41:51 <K> i might have some somewhere
22:42:00 <Ysjoelfir> it looks somehow cute, I wander what it did.
22:42:14 <Ysjoelfir> it is a very strange package though
22:42:16 <K> it says it ws for calculators
22:42:38 <rust_collector> yes
22:43:02 <rust_collector> a ceramic non-blob
22:43:06 <K> it is a wierd package for 1985 though, the had regular big-dip packages as well
22:44:00 <rust_collector> as they made tubes into the 90's, it is not that weird, is it?
22:44:13 <K> maybe
22:44:30 <rust_collector> coffee is ready...
22:44:48 <Ysjoelfir> oh! I didn't have my yuzu tea today
22:44:50 <Ysjoelfir> brb
22:45:08 <rust_collector> oh no!
22:47:11 <Ysjoelfir> it's actually a crucial thing
22:47:39 <rust_collector> I will stay with my roasted bean tea, I think
22:48:45 <rust_collector> I have normal clothes on today, and I did yesterday too. I have to put on some work clothes, or I won't get anything done
22:49:23 <Ysjoelfir> not crucial like that. more like... crucial for a target I set myself
22:49:57 <Ysjoelfir> this video inspired me back then. and it realy seems to be working. https://www.youtube.com/watch?v=xT_YaduPYlk
22:50:07 <rust_collector> how much tea do you "need" in a day?
22:50:14 <Ysjoelfir> one glass
22:52:46 <hsn> glass of tea
22:53:01 <hsn> my stomach keeps roaring
22:53:07 <hsn> lemon.com
22:53:09 <rust_collector> I think he has some relatives in poland
22:53:19 <hsn> lemon
22:54:31 <hsn> http://banana.com/ << what is dis
22:54:36 <hsn> robots
22:55:47 <Ysjoelfir> XD
22:57:29 <hsn> where did lemon go ?
22:57:42 <Ysjoelfir> I assume he fell asleep
22:58:08 <rust_collector> he got tangled up in all his cables, and can not reach the keyboard
23:02:50 <Lemon> sorry I was walking the doggo
23:03:03 <rust_collector> crap, that was a long video
23:04:29 <hsn> ok i logged random data lemon
23:04:42 <Lemon> nice !
23:05:01 <hsn> its 53k now
23:05:21 <Lemon> you changed anything ?
23:05:49 <hsn> i added only ,, shall i send u ?
23:06:23 <Lemon> what did you add ? yes why not thats nice of you :>
23:06:55 <hsn> currently inside (TimerGraph_Tick) ^ after (Chart.Series("Degrees Celcius").Points.AddXY) i added this function : (logDataSub())
23:07:01 <EEVBlog> New EEVBlog Tweet: With all this talk about the WHO, this is the video you MUST watch. https://t.co/uJtkIJYWOB
23:07:07 <hsn> so u can see it after i send u ..
23:07:20 <Lemon> but what is it doing ? :>
23:07:27 <Lemon> to log it into a file ?
23:07:39 <hsn> yes
23:07:42 <hsn> lemon.txt
23:07:47 <Lemon> ha nice !
23:08:13 <Lemon> ideally, it would be nice if it can save it with a button, and load it laater to read the graph
23:08:13 <hsn> where is the share web
23:08:22 <Lemon> but idk how it will handle thousands of plots
23:08:35 <rust_collector> you will find out
23:08:39 <Lemon> ho I just typed 'upload files' in google
23:09:07 <rust_collector> and, logs takes fa space, said a guy called lemon
23:09:13 <hsn> https://ufile.io/vp36dqz0
23:09:23 <Lemon> fa space ?
23:09:26 <Lemon> thanks bud
23:09:38 <rust_collector> yes, almost no
23:09:48 <hsn> its not so great .. it just save (time and decimal value) as text seperated by (" - ")
23:09:53 <hsn> just see the function
23:10:44 <hsn> also i added button on the left that runs a random generator timer
23:10:48 <hsn> just to test
23:10:59 <hsn> and the function saves file every 1k sample
23:11:30 <hsn> so u can delete it + delete that timer assosiated with it
23:12:22 <Lemon> thats neat ! lets see if it can handle a lot of lines
23:12:31 <Lemon> I need to find a way to create the chart with that file
23:13:58 <rust_collector> Lemon, did you keep all the readings in memory?
23:14:08 <hsn> i think u should limit your points into the chart ..
23:14:34 <Lemon> I dont know how it works exactly as its with that ms chart function but yes I think it keeps it in memory
23:14:43 <rust_collector> ah
23:15:01 <hsn> he does .. append to chart object (mschart) im not familier with it .. i guess it does grow the heap and after some time it get slow
23:15:36 <rust_collector> how many points do you need, to make a graph of a reasonable time?
23:16:03 <hsn> i think u can find a function that flushes the old data in the (mschart) thingy
23:16:05 <Lemon> well I like having as much point as possible as it gives me the possibility to zoom, and see slight variations
23:16:20 <Lemon> it takes 324k samples per 24h
23:16:37 <hsn> but what r u logging ?
23:16:42 <rust_collector> yes, but... you can probably make a graph out of the text file later?
23:16:53 <hsn> +1 ^
23:17:27 <Lemon> yes thats what I want to do, but what will be the performance ? this is unknown
23:17:38 <rust_collector> so if you got a "rolling graph" over a usable time, to look at while it is running, then you can get all the data you want, out of the text file later?
23:17:38 <Lemon> I tried with an excel file, when hitting the save button at 1k samples it froze
23:17:42 <Lemon> with txt file it will be better
23:17:50 <Lemon> but will it handle several 100k's ?
23:18:14 <hsn> the txt?
23:18:19 <hsn> yeah
23:18:22 <Lemon> the load function
23:18:26 <rust_collector> I do not think txt files have much of a limit
23:18:28 <Lemon> like, load a chart from a txt file
23:18:32 <Lemon> and build it with that data
23:19:04 <hsn> i think u can do it on portion .. (load 10k) and step next (10k) ..
23:19:20 <Lemon> like it could save data every hour or so in the same file, and change file every 24h
23:19:41 <Lemon> if it can build a chart with a 24h data file (324k points) it would be perfect
23:19:44 <Lemon> but I fear it will be hard
23:20:00 <hsn> tbh, i would graph 1 out of 10 lines in the text
23:20:06 <hsn> so 324k -> 32k
23:20:11 <hsn> or somthing like that
23:20:17 <Lemon> but then I lose many samples
23:20:21 <Lemon> when rebuilding the chart
23:20:57 <hsn> and then build another function that (loads all samples but in batches) => (zoomed)
23:20:58 <rust_collector> what is that then, if you remove 90% you get one reading every... 6 seconds?
23:21:24 <Lemon> every 3 seconds ? idk
23:21:26 <Lemon> im bad at maths
23:21:50 <rust_collector> me too.
23:22:00 <rust_collector> yeah, 3-ish
23:22:10 <hsn> yeah .. 1500 points would be 1 sample per minute and then u can zoom there
23:23:37 <rust_collector> I just wonder... if you want to see everything... how will you keep your mom from letting the cats out, when you are measuring htings?
23:23:48 <Lemon> thats another problem :>
23:24:18 <rust_collector> if you could have hsn fix it in software, that would be neat
23:26:15 <Lemon> I think, the best way to do it is : add a save/load function, so you can save anytime, same for loading and see previous files, and save automaticaly (add a button to disable it if needed) every 1 hour in the same file, change file every 24h.
23:26:42 <Lemon> and every 24h, clean the chart
23:26:47 <Lemon> that way performance dont suffer
23:26:56 <Lemon> the chart can handle 24h of data without problem
23:27:04 <Lemon> saving it should be fine
23:27:07 <Lemon> loading it might be hard
23:27:21 <Lemon> that way I keep every data
23:27:29 <hsn> then u can save date with (date.txt) ?
23:27:34 <rust_collector> yes
23:27:39 <Lemon> auto save every hour, every 24h change file/clean chart, and go on
23:27:52 <Lemon> yeah autosave with date of start or whatever
23:28:06 <Lemon> and a save button where you specify the name like I did for pngs
23:28:24 <Lemon> my only concern is building the chart with a txt file that got 24h of data
23:28:51 <hsn> np, tinker with it .. i've to go now .. i can help on loading txt data later
23:29:09 <hsn> see u i ve to go
23:29:11 <Lemon> sure thanks for everything
23:29:15 <Lemon> see you !
23:29:19 <rust_collector> maybe you should use a "make chart from txt file" program to do that, and not put all the things in one blob
23:30:04 <rust_collector> you could always start that program from inside your blob, I guess
23:30:17 <Lemon> idk if it will change anything
23:31:01 <rust_collector> No, and I have absolutely no idea. I just like the idea of one program doing one thing well, then... yes, I am of the more unix-y kind
