00:02:15 <T3sl4> mmm, things
00:02:41 * Ampera sucks T3sl4's thing
00:03:00 <T3sl4> ohhh myyy
00:05:52 <Ampera> I have cats
00:06:04 <Ampera> They are being cats, right next to me
00:06:07 <Ampera> Two of em
00:06:19 * T3sl4 scritches Ampera behind the ear
00:06:30 <T3sl4> tell them they're both butts
00:07:28 <Ampera> https://cdn.discordapp.com/attachments/310478241989263371/682212047672442933/IMG_20200226_080649.jpg
00:07:36 <Ampera> They already know
00:12:59 <hsn93> the wise cat is on the right
00:13:16 <Ampera> He is.
00:14:30 <Ampera> https://cdn.discordapp.com/attachments/310478241989263371/682213857501904924/IMG_20200226_081353.jpg
00:14:40 <Ampera> Here's another little troublemaker
00:15:10 <hsn93> not soo wise like the other one
00:15:34 <Ampera> No she's the wisest of them all
00:15:58 <hsn93> u know aaronanimal ?

00:23:00 <rust_collector> hello eevblaaarrrggggg
00:23:13 <Ampera> Hullo
00:23:22 <Ampera> I am in a car on my way to work
00:23:25 <rust_collector> is the bot dead or something?
00:23:28 <Ysjoelfir> Helly rusty
00:23:33 <rust_collector> oh. I just got home
00:23:47 <Lemon> waddup rusty
00:23:59 <Ampera> https://cdn.discordapp.com/attachments/310478241989263371/682215989357969409/IMG_20200226_081734.jpg
00:24:18 <Ampera> Eevblog Debug and Status
00:24:31 <rust_collector> wow, finally a cat that looks like a proper cat
00:24:34 <Ampera> Eevblog about
00:24:34 <EEVBlog> EEVBot, programmed by Ampera. Version 2.1
00:24:42 <Ampera> No it's still here
00:24:48 <rust_collector> oh well
00:25:12 <Ampera> I got the flash just right on that one though
00:25:45 <rust_collector> is it still crawling around and bumping into things?
00:26:39 <Ampera> The cat or the bot?
00:27:16 <rust_collector> my phone camera always think it is night, and tries to do some tricks with the flash, but it usually ends up with a yellow picture, or pretty much black
00:27:21 <rust_collector> I did mean the cat
00:28:56 <rust_collector> Lemon, what did you get in the mail today?
00:29:18 <Lemon> nothin ! but I built the pack for the lcr meter
00:29:24 <Ampera> The cat is crawling around and occasionally broadsides furniture
00:29:25 <Lemon> well a crude pack, without any bms
00:30:04 <rust_collector> good flash
00:30:24 <rust_collector> not many people reflash their cats these days
00:44:05 Join: hsn993 ([email protected]) to #EEVblog
00:44:37 <Lemon> the lcr meter takes 34 seconds to draw 1mv out of the pack
00:47:01 <Ampera> rust_collector, I want to make sure he's on the latest firmware
00:47:10 <Ampera> these IoT cats can be a real handful
00:47:46 Quit: hsn93 ([email protected]) Ping timeout: 121 seconds
00:47:52 <rust_collector> good good. keep the up to date, because if you miss one update, you can get weird results on the next update
00:51:27 <Ysjoelfir> thats not a scanner, rusty
00:52:28 <rust_collector> meh, prove it...
00:52:47 <Lemon> idk yet the minimum voltage the lcr meter needs yet, but if it can runs on 10v minimum, the pack should last approx 22 hours
00:52:54 <Lemon> which is more than fine
00:53:19 <rust_collector> If I scan a barcode with a cat... will you accept that, or are you going to deny it is a scanner anyway?
00:53:55 <rust_collector> Lemon, I guess it depends on which function you use also?
00:54:03 <Lemon> yeah probably
00:54:13 <Lemon> but well right now it measures random shit
00:54:16 <Lemon> so it shouldnt change much
00:55:01 <Ysjoelfir> Yeah, I would accept that :)
00:55:31 <rust_collector> I broke down, and got myself a microwave transformer today. I do not know why, but... now I have one of those too
00:55:39 <rust_collector> Oh yes, magnet
00:55:40 <Lemon> even if its 15 hours, well I wont use it for hours long
00:55:43 <Ysjoelfir> but keep in mind that CatOS is, besides having some hiccups for a few minutes every day, pretty stable.
00:55:54 <Lemon> you got the magnet out of the magnetron ?
00:55:57 <Lemon> take care about those
00:56:04 <Lemon> theres some berylium inside
00:56:09 <rust_collector> it is Ampera he probably runs his cat on netbsd
00:56:39 <rust_collector> le, no, there is not, and no, I am going to use the transformer itself as an electromagnet
00:56:44 <Ampera> no I do FreeBSD for cats
00:56:51 <Lemon> ha I see
00:57:01 <Lemon> those are bigass transfos
00:57:04 <Lemon> theres a nice cap too
00:57:06 <Lemon> and a diode
00:57:11 <Lemon> some micro rupters too
00:57:24 <Lemon> relays too I think
00:57:25 <rust_collector> I thought it was an oddly small transformer
00:58:16 <rust_collector> I guess they push them pretty hard
00:58:53 <rust_collector> there was 2 more ovens there, I might look at them tomorrow
00:59:49 <rust_collector> and there was a large pile of network switches, and some switch-like device, with molex connectors?
00:59:53 <Ampera> db server that which runs all the testing sites is down
01:00:16 <rust_collector> good times at work
01:00:35 <Ysjoelfir> I am thinking about how much money I can expect when talking with my boss in a few days, when I have my degree certificate...
01:00:48 <Ysjoelfir> The numbers I find on the net are varying widely
01:01:31 <rust_collector> my education gave me nothing. it has noting to do with what I am doing, so that makes sense
01:02:18 <Ysjoelfir> some say that an Electronics B.Eng. gets no more than 36.000€/a, while others say that a B.Eng. can get (with experience, which I have) up to 65.000€/a. I am... irritated.
01:02:33 <rust_collector> but, you will probably get as much as the boss likes you....
01:02:42 <Ampera> looks like everything's eaten shit
01:02:51 <Ysjoelfir> My education doesn't help me either in regards of knowledge... I did that only for the higher pay.
01:05:53 <rust_collector> knowledge is not a good thing in my job. the less of it you have, the more likely you are to keep the job, and probably get promoted, if you are too useless
01:08:22 <Ysjoelfir> That sounds strangely familiar
01:12:51 <Ampera> Now the question is will my ibook last an entire meeting
01:14:38 <rust_collector> that would depend on your anger management skills?
01:17:28 <Ampera> rust_collector, no the battery
01:18:30 <rust_collector> you can have all the battery in the world... if you smash the thing, it will not last long
01:19:18 <rust_collector> grab the cars battery...
01:25:46 <Ysjoelfir> or even better, the car
01:34:02 <Lemon> I wonder if I charge the 3s pack without balancing it, if it will stay somewhat balanced
01:34:11 <Lemon> as all three cells are at like 1-2mv max
01:34:58 <Ysjoelfir> They will, at least until one cell starts to degrade ;)
01:35:10 <rust_collector> try it and see how it goes, over some time
01:35:15 Quit: hsn993 ([email protected]) Ping timeout: 121 seconds
01:35:33 <Lemon> yeah thats what im going to do
01:35:51 <Lemon> am gonna take the trusty fluke 101 with me to see
01:36:06 <rust_collector> where are you going?
01:36:23 Join: hsn993 ([email protected]) to #EEVblog
01:52:29 <Lemon> to the charger, no outlets left here
01:52:37 <Lemon> well it seems its not unbalancing much
01:52:41 <Lemon> its fine for my usage
01:53:13 <rust_collector> probably. just keep an eye on it now and then
01:53:45 <Lemon> yeah
02:01:33 <Lemon> alright taped and secure

03:06:16 <Ysjoelfir> wow... looking through job adverts for engineers.
03:06:57 <Ysjoelfir> "We are building a 1S75P battery pack using 18650 3.7V cells and need to have a balancer designed and built for the battery pack."
03:08:24 <rust_collector> being almost european, I think it is time for a nap
03:09:27 <Ysjoelfir> thats a great idea. So you come over and continue my work while I take a nap`?

06:26:46 <Ysjoelfir> hi
06:27:07 <Lemon> sup :>
06:27:21 <Ysjoelfir> pizza soon.
06:27:29 <Lemon> heh great :>
06:29:22 <Lemon> so the dude with test leads sent it yesterday, and it got today for pickup (just saw the notification late, np)
06:29:39 <Lemon> so for insignificant stuff its blazing fast
06:29:51 <Lemon> but for important stuff it takes a full week and it breaks during transport :>
06:30:30 <Ysjoelfir> xD
06:31:13 <Lemon> well thats something :>
06:31:22 <Lemon> I just miss croco clips, to clip on banana males
06:31:54 <Lemon> the ones I bought with some leads on aliexpress got sent 14 days late...
06:34:25 <Lemon> I realized that I need to make two packs for the Vref
06:34:28 <Lemon> orrrr hmmm
06:34:45 <Lemon> I could just plug it to a supply while the pack is being charged
06:34:54 <Lemon> so its never off
06:35:30 <Ysjoelfir> btw... does it incidentally fit into that golden case?
06:35:49 <Lemon> I think it should fit actually yes
06:36:01 <Lemon> its pretty small

06:36:39 Mode: (by ChanOP) +o T3sl4
06:40:59 <Lemon> the stack on the right of my desk is so heavy that I can use on of the handles at the front of a device to push me or pull me on the rolling chair :>
06:42:35 <Ysjoelfir> lol
06:43:50 <Lemon> id say theres a good 45-50kg
07:06:46 <Lemon> so im trying do display a waveform with the wavetek on the hp 54201d
07:06:50 <Lemon> but its the hardest thing ever
07:06:53 <Lemon> someone send help please
07:07:23 * Ysjoelfir sends some help on the way to le cirtoen
07:07:45 <Lemon> tanks
07:07:51 <Lemon> I get something but it looksl ike noise
07:09:05 <rust_collector> mmmm noise!
07:09:23 <Lemon> ho thats weird I just noticed the display is wobbling a bit
07:12:11 <rust_collector> you did short the power pins when you hauled that thing home, right?
07:12:49 <rust_collector> oh, lasagna
07:13:08 <rust_collector> that is acceptable for breakfast
07:13:46 <Lemon> shorted the power pins ?
07:14:58 <rust_collector> yeah, the wall plug
07:15:45 <Lemon> why that ?
07:15:52 <Lemon> I don't get it
07:16:05 <rust_collector> good, because it is just bullshit
07:17:04 <Lemon> alright xd im tired dude please my brain is already melting with this scope
07:17:09 <Lemon> its so complicated
07:17:36 <rust_collector> does it have an "auto" button?
07:20:21 <Lemon> theres an auto scale, but it says execution not possible
07:20:26 <Lemon> im not even getting noise now :>
07:21:50 <Lemon> I do get something on my tek, so the generator is not the problem
07:31:07 <Lemon> gahhh
07:31:10 <Lemon> I dont know
07:31:34 <rust_collector> no, but figure it out
07:31:50 <rust_collector> what does it look like on the tek?
07:32:18 <Lemon> a regular sinewave :>
07:32:20 <Lemon> I just get nothing
07:32:26 <Lemon> not even the noise I had before
07:32:35 <Lemon> im trying to mess up with some shit but man its so complicated
07:34:32 <rust_collector> and it is not "outside the screen"?
07:34:49 <Lemon> I guess it is but good luck to move the waveform
07:34:56 <Lemon> im reading the manual :> https://www.qsl.net/n9zia//test/HP54201AD_Operating_Manual.pdf
07:35:00 <Lemon> here it is if you want some fun
07:39:47 <rust_collector> I am a simple person, I like knobs
07:40:09 <Lemon> me too
07:40:17 <Lemon> ho dude the autoscale worked but it said no signal
07:40:21 <Lemon> wtf seriously
07:40:47 <rust_collector> you did hit the run button?
07:41:56 <Lemon> I tried it its not on stop
07:42:11 <rust_collector> ok
07:42:41 <rust_collector> 2 weeks or so ago, I jumped in a forklift, and the damn thing did not want to start
07:43:12 <rust_collector> I tried putting in neutral, set handbrake, bounced in the seat...
07:43:19 <rust_collector> well, it was electric
07:43:20 <mamalala> haha
07:43:28 <mamalala> someone is having fun with that scope :P
07:43:35 <Lemon> help meeeeeeeeeee
07:43:39 <mamalala> keep in mind that only channel 2 is working properly
07:43:48 <Lemon> I fiddled around, and Im not even getting anything now !!
07:43:51 <Lemon> yeah im on input 2
07:43:58 <Lemon> feeding it a sinewave from a gen
07:44:02 <Lemon> which is working I tested it
07:44:09 <Lemon> it says 'no signal found'
07:44:16 <Lemon> even if I just plug a probe and touch it like you did
07:44:43 <mamalala> what screen do you have? the one with the four "windows", or just single channel 2?
07:45:07 <mamalala> because, whatever you press on the buttons is acting only on whatever "window" you have selected on the screen :P
07:45:39 <Lemon> yeah I figured that, I just got the channel two window ! but wait I tried those self tests earlier
07:45:40 <mamalala> but rest assured, after a few months of constant use you will get somewhat used to it ... haha
07:45:42 <Lemon> and I abborted one
07:45:47 <Lemon> so that might be the problem
07:45:55 <Lemon> I'll do the calibration one and let it finish to see
07:46:17 <mamalala> that scope sure is fun ... can drive anyone nuts in no time at all
07:46:23 <Lemon> maybe I fucked up something
07:46:29 <Lemon> yeahhhh xd
07:46:33 <Lemon> maybe that channel one is working !
07:46:39 <Lemon> who knows what happened x)
07:46:54 <Lemon> im letting it do the calibration
07:47:10 <Lemon> the other test passed fine

07:48:17 Mode: (by ChanOP) +o T3sl41
07:48:23 <mamalala> i mean, heck, i used that thing for years... and had trouble showing you the basic operation, because i didn't use it in the past 5 or 6 years or so
07:48:42 <Lemon> yeah even peeps on forums were saying you need to go to hp high school xd
07:48:56 <mamalala> that thing is meant for masochists
07:49:03 <mamalala> ... designed by sadists :P
07:49:09 <Lemon> true that :P
07:49:14 <Lemon> have you noticed the screen wobbling ?
07:49:18 <Lemon> its really slight
07:49:34 <Lemon> thats somewhat fun
07:49:37 <mamalala> it's probably because you have it stacked on top of other gear with big transformers
07:50:00 <mamalala> never had that effect before... but then, never had it stacked on top of other gear either
07:50:15 Quit: T3sl4 ([email protected]) Ping timeout: 121 seconds
07:50:33 <Lemon> hmmmm all are off now thats strange
07:50:42 <Lemon> haa
07:50:52 <Lemon> failed chan 1 offset cal and chan 1 gan cal, so yeah
07:50:59 <Lemon> lets see if I get anything on chan 2 now
07:51:13 <Lemon> passed chan 1 hysteresis cal
07:51:42 <Lemon> ha theres my workstation screen next to it
07:51:46 <Lemon> maybe thats the problem
07:51:53 <Lemon> but my other scope isnt wobbling, well
07:51:58 <Lemon> its no big deal
07:52:02 <Lemon> passed chan 1 trigger cal
07:52:24 <Lemon> brb im taking a smoke
07:52:57 <Ysjoelfir> guys, I need your help
07:53:13 <rust_collector> TA ta DAAAAAA!
07:53:15 <mamalala> with what?
07:54:29 <rust_collector> you need google play cards?
07:54:38 <Ysjoelfir> right now I try to create the website for my sidebusiness/self employment. I can't think of a good slogan/phrase that the website template wants to have
07:54:56 <mamalala> "Leave it to the Kraut!"
07:55:16 <rust_collector> what are you supposed to do?
07:55:33 <Ysjoelfir> Like that -> http://pdi.engineering ... The "A sample site" will be replaced with the PDI.Engineering, but what should I replace the amazing payoff with? :D
07:56:04 <Ysjoelfir> engineering work. Schematic and PCB design, creating prototypes,... stuff like that
07:56:29 <Ysjoelfir> If I wouldn't make it a serious business I would love to use the slogan mamalala suggested xD
07:57:17 <mamalala> Ysjoelfir: so... had any time to sift through all these old radio carcasses? :P
07:58:24 <rust_collector> I think that would work, you just have to get known as the kraut, in that world
08:00:41 <rust_collector> and, I think you should leave the "about us" section like it is
08:02:27 <Ysjoelfir> Hmm.... would you think that that's a good idea? I personally would find it... funny? don't know?
08:02:29 <Ampera> did someone say kraut?
08:02:43 <Ysjoelfir> Half-Krauts don't count. ;P
08:02:57 <Ampera> I am fully kraut by citizenship
08:03:20 <Ampera> don't appropriate my sour cabbage status
08:03:27 <Ysjoelfir> xD
08:03:50 <Ysjoelfir> So mr. sour cabbage... what would you say?
08:04:28 <rust_collector> no, you fix it yourself, you cheap bastard
08:04:38 <rust_collector> that gives them an idea
08:04:49 <Ysjoelfir> xD
08:05:51 <rust_collector> I like the slogan TNT has. "yes we can....." with an underscored can
08:06:16 <rust_collector> sure they can, but maybe we just don't feel like it today?
08:10:39 <Ysjoelfir> :D nice
08:10:50 <Ysjoelfir> I actually think about using the kraut thing...
08:11:24 <rust_collector> websites are hard
08:11:43 <mamalala> "German engineering - We do it big scale"
08:11:53 <mamalala> :P
08:11:57 <Lemon> haaaaa
08:11:59 <Lemon> I got a signal !
08:12:02 <Lemon> finally
08:12:23 <mamalala> sorry... had some beers... otherwise i couldn't cope with all that spreadsheet crap i have to do right now
08:12:25 <rust_collector> make your call, before it goes away
08:17:32 <Lemon> well it seems that auto-cal fixed it
08:18:06 <Lemon> failed chan 1 offset cal and chan 1 gan cal
08:18:12 <Lemon> I need to look into that
08:18:57 <mamalala> Lemon: yea, as said, chan 1 is broken ... dunno if that scope has offset and gain in a frontend, or if it is integrated in that nasty, custom chip
08:19:30 <Lemon> I'll dig the net about it :>
08:19:31 <mamalala> never looked into it, just groaned to myself and used only chan 2
08:20:02 <Lemon> its basically the same as the 54201A version, with the logic analyzer option
08:20:07 <Lemon> so spares might be obtainable
08:20:12 <Lemon> but yeah, I rarely use two channels honestly
08:20:46 <mamalala> well, for now you might not ... but believe me, once you used several channels at once, you don't want to go back to just a single channel
08:21:02 <Lemon> yeah thats true !
08:21:04 <mamalala> having the proper timing relation between several channels is invaluable to have
08:21:16 <Lemon> well at least I have my other tek, and the handheld tek too :P
08:21:40 <Lemon> I can't say that I don't have any tools to work with, for a beginner like me x)
08:21:59 <mamalala> look at that guy ... multi scopes, like a boss ... but driving a half dead ford ... what a cheapskate ... haha
08:22:16 <Lemon> haha ofc !!
08:22:24 <Lemon> speaking of the ford
08:22:24 <Ysjoelfir> http://pdi.engineering
08:22:31 <Ysjoelfir> I think that looks actually realy good xD
08:22:45 <Lemon> ive got to do the annual check AND new papers for it, as it was at my fathers...
08:22:55 <Lemon> speaking of that, 3k euros in the drain for the succession...
08:22:59 <Lemon> they are really vampires
08:23:00 <rust_collector> it does look about right
08:23:13 <mamalala> Ysjoelfir: i just hopr that that pcb image is one you took of your own designs
08:23:19 <mamalala> *hope
08:23:41 <Lemon> Comprehensum, quod cognitum non habet?
08:23:47 <Lemon> I do comprehensum yes
08:23:52 <rust_collector> No, he did design the iphone 95
08:24:28 <mamalala> the only latin i know is the expansion of the german word for marriage, "Ehe" ... and that is "Errare humanum est"
08:25:28 <Ysjoelfir> It is, mamalala. It's an addon board for a Soundcard.
08:25:39 <Ysjoelfir> Those latin texts are just fillers :)
08:25:46 <mamalala> Ysjoelfir: well, but is it yours?
08:26:05 <mamalala> i mean, your design
08:27:00 <Ysjoelfir> Yes. Admittedly, I copied a part of that board so that it is compatible to the bracket, but I made it
08:27:00 <rust_collector> http://nietzsche-ipsum.com/
08:27:29 <mamalala> because i find it highly irritating if websites use stock photos for such stuff, even though they are supposed to actually do that stuff ... as if they are ashamed of their own work
08:28:39 <Lemon> ok so I did some selftest, cpu/memory seems fine, on aquisition/trigger it shows : FAILED chan1 test RT/RR, same for chan2, failed state pod test 7. sequence test. qual/clk test. restart test. bit fault test
08:28:47 <Lemon> quite a lot of failed stuff dayum xd
08:29:17 <mamalala> not sure, but i think the pods need to be connected maybe?
08:29:25 <Ysjoelfir> haha, yes, I absolutela hate that... which is why I took the photo and used one of my things. But I want to exchange it with a bord that uses the color scheme I use nowadays. OR: get a rotating... banner... thing, so that it can show more things I do, like one picture of a schematic, one of a layout, one of a finished PCB,...
08:29:38 <Lemon> yes maybe but for the other one I have no idea !
08:30:14 <rust_collector> no no nooooo, ONE pic, or at least make them click to scroll thru the pics. no auto anything
08:30:47 <mamalala> Ysjoelfir: rotating banners only work with a MARQUEE style text!!!
08:31:05 <mamalala> (and i mean rotating in the literal sense!)
08:31:20 <rust_collector> spinning pics
08:31:33 <rust_collector> of a cat...
08:31:52 <rust_collector> every minute or so, cat spins across the screen

08:34:57 <rust_collector> Oh, make a line at the bottom, with a rainbow
08:35:15 <Ysjoelfir> `but I'm not gay?
08:35:22 <rust_collector> then if someone clicks it, you get nyan cat
08:35:29 <Ysjoelfir> lol
08:35:44 <Ysjoelfir> I like nyan cat, but... nah. I want to stay a bit serious^^
08:37:06 <rust_collector> one of my favourite things, when the pc was hooked up to to the tv. put on nyan cat 35 million days, and turn off the tv screen, go to work
08:37:47 <Ysjoelfir> lol
08:38:28 <mamalala> btw... for those interrested: http://atelier-klippel.de/me.html
08:39:06 <Ysjoelfir> I like the beer!
08:39:07 <mamalala> "I want to stay a bit serious"... said the guy who put "Leave it to the Kraut" on his page :P
08:39:55 <Ysjoelfir> I actually have an idea with that^^
08:40:05 <Ysjoelfir> you know our good old "made in germany" thing?
08:40:19 <Ysjoelfir> I want to reference that somehow :)
08:40:32 <mamalala> hehe
08:41:01 <mamalala> "Leave it to the Kraut - Made in Germany"
08:41:12 <Ysjoelfir> well, maybe not like that ;)
08:41:34 <Ysjoelfir> more like "if you leave it to the kraut you can expect quality made in germany" or something like that
08:41:53 <Lemon> hey mamalala, how do you connect them pods ?
08:41:59 <Lemon> do I need to unscrew that plate at the back ?
08:42:10 <mamalala> Lemon: yes
08:42:23 <Lemon> better turn it off first I guess ?
08:43:23 <mamalala> obviously
08:43:42 <mamalala> but be aware that i never used/connected the pods...
08:45:08 <Lemon> no problems :> its just to see if tests pass
08:46:35 <rust_collector> I think I will go get some more lasagna
08:51:10 <Lemon> fiou theres some inhabitants in there :p
08:51:18 <Lemon> well all pod test passed !!
08:51:43 <Lemon> only thing that doesnt work is those chan 1/chan2 test RT/RR, which comes from the analog board according to the service manual
08:51:54 <rust_collector> ok, what is a pod anyway?
08:52:16 <Lemon> its those thingies used to connect probes for logic board analyzing
08:52:32 <rust_collector> mmkay
08:56:03 <Lemon> I could try to reseat the analog board
08:56:22 <Lemon> but its starting to be some unkown and never done before stuff for me
08:58:22 <rust_collector> well, I have a feeling that one has a board you might be able to plug in and yank out. not like the old things, with 300 wires and resistors and pot shafts and stuff to remove first
08:59:02 <Lemon> yeah seems its made like this
09:07:14 <Lemon> after trying another self test, now its only the chan 1 thats failing, as its supposed to be
09:10:26 <rust_collector> heh
09:10:54 <rust_collector> you can get one of these, to make you feel better: https://www.finn.no/bap/forsale/ad.html?finnkode=171223864
09:13:02 <Lemon> nah im stopping for a bit the aquisition time
09:13:17 <rust_collector> wow
09:13:19 <Lemon> the budget is done :>
09:13:31 <Lemon> if I want more stuff I need to sell the laptop/desktop
09:13:51 <rust_collector> I think I have heard about that... some time ago?
09:14:12 <MrMobodies> Hello
09:14:12 <Lemon> and as much as I love those analog devices, I have already a few (+ a box full of them that I need to fix) I'd prefer to get other things :>
09:14:26 <Lemon> like an electrometer, or the 18ghz plugin for the counter, etc
09:14:27 <Lemon> hello boi
09:14:42 <MrMobodies> shouldn't sell your laptop/desktop
09:14:57 <rust_collector> no, you should give it to MrMobodies
09:15:10 <rust_collector> he can make you dinner in return
09:15:13 <MrMobodies> oh jokey
09:15:35 <rust_collector> do you think he should rent it out?
09:15:46 <MrMobodies> he could rent out his skills
09:16:04 <MrMobodies> in soldering and repairng boards
09:16:40 <MrMobodies> nothing better than someone who is interested and enthusiastic in what they do
09:16:52 <rust_collector> Lemon, do you do any gaming?
09:23:30 <MrMobodies> I use to only play one game, and that was Unrealtournament the one that came out in 1999.
09:27:28 <Lemon> im not gaming anymore no
09:27:49 <Lemon> and the laptop im selling is not used anymore, same for the desktop
09:31:58 <MrMobodies> what do you use for this IRC?
09:33:03 <MrMobodies> Oh sorry, silly me, most likely a phone or maybe a tablet
09:33:19 <Lemon> no, anotther desktop :>
09:33:28 <Lemon> a workstation I built end of last year
09:35:51 <Lemon> lets build the battery pack for the Vref
09:35:52 <MrMobodies> oh wonderful so you have got stuff to sell
09:36:00 <Lemon> gotta find some close in voltage cells first
09:36:13 <Lemon> with mah beautiful fluke 8502a <3333
09:36:33 <Lemon> im so happy about the new gear !
09:43:47 <MrMobodies> That looks really good
09:43:48 <MrMobodies> https://images.bonanzastatic.com/afu/images/be49/b5bd/3949_6646623050/s-l1600.jpg
09:44:01 <MrMobodies> rack mounted as well
09:46:28 <MrMobodies> something about those knobs
09:46:29 <MrMobodies> https://i.ebayimg.com/images/g/mrwAAOSwK0pbvO62/s-l1600.jpg
09:46:45 <MrMobodies> reminds me of the smell of peculating coffee
09:47:01 <MrMobodies> and coffee cakes
09:47:35 <rust_collector> ok, have fun. I am going back into hibernation
09:48:50 <Lemon> hah mine got the same sticker marks :>
09:48:52 <Lemon> well, shadows
09:48:55 <Lemon> night rust !
09:49:09 <Lemon> I found 4 cells that are +- 2mv within each others, good enough
09:49:15 <MrMobodies> oh hibernation
09:49:21 <rust_collector> night
09:49:31 <MrMobodies> what type of cells? does it use
09:49:35 <MrMobodies> nigthy
09:49:45 <Lemon> ho I'll use 18650, I have a lot of them
09:49:59 <Lemon> I need 14-16v for a Vref, so 4 of them will be fine
09:51:29 <Lemon> btw mrmobodies, heres what I brought back from germany this weekend https://imgur.com/a/MZzcTqn
09:51:39 <Lemon> whats on the table, first picture :>
09:51:50 <Lemon> from ysjoelfir and mamalala
09:52:20 <Ysjoelfir> he even drove to REWE to steal that red basket!!! :P
09:52:30 <MrMobodies> Like your stuff I see you are kitted up
09:52:41 <MrMobodies> All nice and neat there plenty of room
09:53:36 <Lemon> haha ! el famoso red basket :P
09:53:43 <MrMobodies> blob:https://imgur.com/caa640bc-9859-48bc-bc41-ba7c473a4f54
09:53:44 <MrMobodies> oops
09:53:44 <Lemon> and the lidl bag too !
09:53:48 <mamalala> except for the tiny kitty scratchers he has :P
09:53:52 <MrMobodies> https://i.imgur.com/8Nh25Hb.jpg
09:53:58 <MrMobodies> is that monitor a packard bell?
09:54:12 <MrMobodies> the crt in the back highlighted
09:54:15 <Lemon> an old sony flat crt :>
09:54:25 <Lemon> yeah but its no game mamalala you got the biggest ever :P
09:54:28 <MrMobodies> oh no wonder it still still works
09:55:27 <Lemon> and yeah we have 17 cats there
09:56:19 <MrMobodies> I see you got a cat
09:56:22 <MrMobodies> oh
09:56:30 <MrMobodies> I didn't see it at first in the picture
09:57:00 <DHess_US> MrMobodies, I have used that series. The style is very 80s.
09:57:42 <DHess_US> They are comparable to the HP equivalents of the time which came in the same form factor. I prefer the Fluke LED display to the HP LCD though.
09:58:02 <DHess_US> Everything was an option on those. RMS, AC, ohms, whatever.
09:58:23 <Lemon> gladly, I got almost all options !
09:58:24 <MrMobodies> option? put the addons in them?
09:58:29 <MrMobodies> I see
09:58:36 <Lemon> I miss only one, the dreaded cal-mem :PP
09:58:42 <DHess_US> Things like ohms and current were options.
09:58:46 <Lemon> but its one of my mission, I need to find it !
10:00:05 <MrMobodies> I see you've got an oven in there too
10:00:21 <MrMobodies> you heat boards up in there?
10:01:18 <Lemon> nope only us, and a few meals :P
10:01:59 <MrMobodies> oh, there is a thing in that red box that looks like a control of a Weller soldering iron
10:02:12 <MrMobodies> near a volt meter
10:02:42 <Lemon> its a powermeter !
10:02:53 <Lemon> that also shows volts, amps and phase if im right
10:03:01 <MrMobodies> oh I see it has terminals on the side as I brightened the picture
10:03:27 <MrMobodies> it looks a bit at first to me like one the Multi functions ones with the solder sucker
10:04:31 <MrMobodies> Just noticed above 17 cats?
10:04:50 <Lemon> yes :> and a doggo !
10:06:33 <MrMobodies> Does your dog stand up and watch every thing you do with especially with the equipment?
10:06:58 <MrMobodies> I like it when they do that
10:08:19 <Lemon> hooo not this one, only thing for what he wakes up is food
10:08:37 <Lemon> or to raid nearby trashbags
10:09:06 <Lemon> he;s 14.5 y/o :>
10:10:50 <MrMobodies> Quite a lot to feed though
10:11:15 <MrMobodies> maybe there a lots of prey out there
10:11:30 <MrMobodies> oops i mean the cats
10:14:21 <MrMobodies> I don't have many cats around my area, just some that visit in the night and activate the floodlight outside
10:14:53 <MrMobodies> there is one at the pub but you don't pet it or it bites
10:15:57 <Lemon> if you count all the food + eventual meds, thats approx 400 euros per month
10:17:10 <Lemon> 15.62267v
10:17:13 <MrMobodies> the company is very nice with the cats
10:17:25 <Lemon> ok im pasting that down, starting time of the battery powering the vref
10:17:31 <MrMobodies> 8 digit count
10:17:38 <Lemon> 6.5 :>
10:18:31 <Lemon> I'll see the state of the battery tommorow to evaluate the consumption
10:18:31 * Ysjoelfir moves his body to bed.
10:18:35 <Ysjoelfir> have a good night all
10:18:43 <Lemon> but looking at it it looks like 60-80ma
10:18:45 <Lemon> night dude
10:18:48 <MrMobodies> nighty
10:19:00 <MrMobodies> 60- 80 ma an hour?
10:19:00 Quit: Ysjoelfir ([email protected]) Connection closed
10:20:35 <Lemon> yeaha close to that
10:20:48 <Lemon> but its warming up
10:20:55 <Lemon> it should eat less soon I think
10:21:03 <Lemon> its not in the best environnement as theres no enclosures
10:21:13 <Lemon> but its to get a rough estimation of the worst case
10:22:27 <MrMobodies> battery pack totals to something like 16v?
10:24:56 <MrMobodies> So 4 or so 18650 cells 3000 mah, 3000/80 37.5 hours
10:25:29 <MrMobodies> and you'd put in the balancer for the batteries to charge in there
10:29:40 <MrMobodies> just seeing Thunderfoots recent video
10:29:43 <MrMobodies> https://www.youtube.com/watch?v=5tpsoWx7xmY
10:30:19 <MrMobodies> I notice she seems to smile in there a lot
10:35:18 <Lemon> ho I wont use a balance board
10:35:34 <Lemon> for such small packs if you monitor them and if they are from the same batch, and well matched
10:35:37 <Lemon> its fine
10:35:47 <Lemon> sometimes you need to drain a cell a bit and go
10:36:11 <Lemon> but well idk if I'll have the patience to charge the pack every day as it will be on 24/7
10:36:16 <Lemon> I might just use it from time to time
10:36:21 <MrMobodies> I got a power bank with 8 of them in there
10:36:32 <MrMobodies> I don't trust it to charge them I use a Skyrc MC 3000 charger
10:36:38 <MrMobodies> to cycle them
10:36:49 <Lemon> yeah im using a fairly decent charger
10:36:51 <MrMobodies> what is unique about this power bank, it has a DC out
10:37:02 <MrMobodies> and you can adjust between 0.1v to 24v
10:37:10 <MrMobodies> but I just use it for 12v stuff
10:37:21 <Lemon> thats neat I might build one later
10:37:27 <MrMobodies> https://www.aliexpress.com/item/32485864933.html
10:37:35 <MrMobodies> maybe you can build a bigger better one
10:37:38 <Lemon> I have like, 45 cells left or something
10:37:42 <Lemon> besides some that I salvaged
10:38:05 <MrMobodies> it would be nice and make the voltage controls in such a way that can't easily be changed
10:38:20 <MrMobodies> I mean accidentally adjusted
10:39:31 <Lemon> yeah I'll see
10:39:35 <MrMobodies> with all those cells, different states how would you wire them up
10:40:01 <MrMobodies> parallel with a regulator controller for each one?
10:40:11 <MrMobodies> so you can charge them too
10:40:26 <MrMobodies> but that would be ideal
10:40:39 <MrMobodies> ah no sorry, voltage maybe too low
10:41:35 <Lemon> probably like a 6s something p pack
10:41:43 <Lemon> to have a 24v ouput
10:41:50 <Lemon> and a step down board
10:42:00 <MrMobodies> by finding the matching ones and pair them
10:42:09 <Lemon> ho I'll use a bms this time
10:42:17 <Lemon> thats better for a big pack
10:42:18 <MrMobodies> bms?
10:42:25 <Lemon> battery management system
10:43:23 <MrMobodies> once it is being built maybe some Quickcharging usb outputs could be handy
10:47:11 <Lemon> yeah
10:47:22 <Lemon> I have a few things that need to be done first, like building a nice box for a variac
10:49:08 <MrMobodies> I would be looking forward to some pictures on that power bank
10:50:48 <Lemon> ho for sure !
10:50:58 <Lemon> but for now, I got to sleep :>
10:51:06 <Lemon> my eyes are closing
10:51:14 <Lemon> we'll see tommorow how much that Vref consumed
10:52:11 <Lemon> it used approx 58mv in 35 minutes
10:52:20 <Lemon> well, see you tommorow maybe !
10:52:27 <Lemon> night :>

12:02:57 <DHess_US> *headdesk* Just took the checksum of a checksum file.
12:05:41 <mamalala> DHess_US: can't hurt to double check things :P
12:06:20 <DHess_US> Interestingly enough the two checksum files of the same content have different checksums.
12:06:43 <mamalala> ?
12:07:08 <mamalala> the checksum of the checksum file wouldn't be "files of the same content"
12:07:26 <mamalala> compared to the checksum of the original file, that is
12:07:40 <DHess_US> Verifying that a new RAID is working correctly. Copied 1.2TB over to it., checksummed both volumes, swapped checksum files, and am now checking the checksums.
12:07:42 Join: NoNo ([email protected]) to #EEVblog
12:08:32 Part: NoNo ([email protected]) from #EEVblog
12:08:54 <mamalala> that assumes that both volumes are an exact byte copy, volume-wise... and that no changes have occured between checks ...
12:09:39 <mamalala> just copying files between volumes will surely result in different checksums
12:10:29 <DHess_US> That should be exactly the case.
12:10:44 <DHess_US> Each volume should have an identical set of files now.
12:11:00 <mamalala> also, if you check the volumes as such (on linux, for example /dev/md0 against /dev/md1), you probably will get different checksums anyways, since that includes raid info stored in that volume which is otherwise not visible to the file system
12:11:06 <DHess_US> Looks like what happened is when I made the checksums for each volume, the program did the files in different orders.
12:11:24 <DHess_US> No, this was at the file level.
12:11:29 <mamalala> ah, ok ...
12:11:48 <mamalala> but you didn't store the checksum file on said volume then, did you?
12:11:51 <DHess_US> If I grab the properties of everything, the byte counts, folder counts, and file counts match exactly.
12:12:09 <DHess_US> I did, but the checksum program doesn't checksum the file it is making.
12:12:18 <DHess_US> That would be silly.
12:12:37 <mamalala> does the checksum tool you use take other information in as well, besides the raw content of the file? like creation date, last modified date, etc?
12:12:45 <DHess_US> For technical reasons it has to make the file with the list of checksums on the drive or the parent directly.
12:12:47 <DHess_US> directory
12:12:55 <DHess_US> Nope
12:13:26 <DHess_US> If I tell it to make the checksum file somewhere else, then it makes all of the paths absolute.
12:13:37 <DHess_US> Which has to be deliberate but it is annoying.
12:14:12 <DHess_US> Moving everything from a 6 drive RAID6 to a 2 drive RAID1
12:14:17 <mamalala> hmm, then it may be worthwhile to do a script that compares file against file and then stops on the first mismatch, so you can see where the problem is
12:14:32 <DHess_US> Then I will pull the 6 drives, and expand the RAID1 to a 4 drive RAID5
12:14:44 <mamalala> on unix-like systems that would be trivial, i guess... dunno about windows
12:14:58 <DHess_US> No problem yet. Have to wait for the checksums to finish comparing now.
12:15:09 <DHess_US> The program just used different file orders for some reason.

19:15:35 <T3sl41> remember frequency is inverse with time, the more zoomed in one is, the worse the other is
19:17:59 <mamalala> HMMM
19:18:05 <mamalala> (sorry)
19:18:31 <mamalala> depends on the frequency of your drug intake ... and how good you can take it ...
19:19:12 <mamalala> because then, you might get more zoomed in while increasing the frequency :P

19:27:14 <mamalala> jeez ... i have been doing silly, pointless statistics spreadsheets all night
19:27:31 <hsn993> fft is actually same channel but i believe minimum i can get is (12khz) per grid unit
19:27:41 <mamalala> just because some self-proclaimed organization doesn't really know how metrology works
19:27:47 <mamalala> what a bunch of wankers
19:28:15 <Ysjoelfir> metrology? what is that? 0:-)
19:28:44 <T3sl41> sounds like a wooly mess :P
19:28:44 <mamalala> Ysjoelfir: yea... i've been fighting them for over two years now ...
19:29:09 <mamalala> each time it comes to a vote, they decide that just a bit more statistics is needed ... for a really simple thing
19:29:16 <mamalala> T3sl41: yea, indeed
19:29:27 <hsn993> this zoom fft: 1x -> https://snipboard.io/3LHjmi.jpg
19:29:53 <T3sl41> that looks like a, yes, a rect window
19:30:20 <mamalala> but i guess that is what happens if politics get in the way of actual data... they all are happy to wank each others balls, because the members pay... and doing a friend a favour is better than actual facts

19:37:41 <Ysjoelfir> Interesting... I found a job advert for writing application notes. shouldn't that be done by the manufacturer of the IC themselves? I didn't know that this was a thing you outsorce nowadays
19:37:57 <T3sl41> ha
19:37:59 <T3sl41> hahaha
19:38:08 <T3sl41> oh you sweet summer child, have you seen the quality of the average appnote?
19:38:27 <Ysjoelfir> well, yes, but I thought they just don't care anymore :D
19:38:36 <T3sl41> you aren't wrong :D
19:38:38 <hsn993> outsource is bad idea
19:40:19 <mamalala> hsn993: btw, 1khz can be quite low for these software fft's in scopes... it may well be that this is at the very start of the fft bins it shows
19:40:33 <mamalala> at least on the rigol that is the case
19:40:50 <mamalala> also, your scope timebase setting affects what the fft shows
19:41:14 <Ysjoelfir> I think about proposing for that appnote job. Lets see how shitty of an appnote of an IC I don't even know I can write :D
19:41:37 <mamalala> "this is the chip. connect stuff to it, done!"
19:41:49 <hsn993> yes that what i ment thats its minimum span is too large
19:41:59 <hsn993> (span) is right word here right?

19:42:02 <Ysjoelfir> basically like that mamalala^^
19:43:12 <hsn993> but then (that 1khz) is square so i should see the harmonics?
19:43:36 <T3sl41> you did in the other one

19:51:06 <Halcyon> What's wrong with stronger coffee?
19:51:15 <Ysjoelfir> so I went to the coffee machine (which I sold to the company and which is maintained by me), saw it, and turned around, nearly crying

19:57:59 <Halcyon> We have better things to do
19:58:15 <Halcyon> Besides, in Australia, copyright infringement is a civil matter, not a Police matter
19:58:39 <Ysjoelfir> oh, is it?
19:58:41 <Halcyon> Yep
19:59:18 <Halcyon> And also, those pre-roll things at the start of DVD's etc... is a lie... downloading movies isn't classed as stealing (here). A court has ruled that copyright infringement doesn't equate to larceny
19:59:27 <Halcyon> In fact, mere downloading isn't illegal at all
20:00:23 <Ysjoelfir> lol... nice :) good to know that.
20:00:38 * Ysjoelfir is back soon
20:00:56 Quit: hsn93 ([email protected]) Ping timeout: 121 seconds
20:02:16 <Halcyon> Yep, there has never been anyone prosecuted in Australia for downloading a film. The whole Dallas buyers club thing was a joke.
20:02:37 <Halcyon> The people who got a stern warning letter from their ISP were those who were uploading and sharing
20:03:09 <Halcyon> And even then, the ISPs couldn't care less. They were basically told to send those emails out to appear to be "doing something"
20:03:43 * Ysjoelfir returned
20:04:07 <Ysjoelfir> that sounds.... strange, if you see the whole hype about filesharing is such a baaaaad thing, and the TV commercials we had here in germany for many years
20:04:50 <Halcyon> Look, if you upload infringing copies, you can get into trouble. Copyright holders can sue you. Likewise if you start making physical copies of things and sell them, Police can get involved.
20:06:08 <Ysjoelfir> well, sounds correct to me
20:06:31 <Halcyon> The act basically deals with "copying"... downloading is not making an infringing copy (under the definition of our law)
20:07:39 <Ysjoelfir> and then comes germany and bombards you with "advertisments" like that: https://www.youtube.com/watch?v=GCm-dm7DY6s
20:08:50 <Halcyon> "Piracy" has a different meaning under our law
20:08:56 <Halcyon> (which doesn't including downloading)
20:10:54 <Halcyon> Basically without getting too technical, if they made downloading and storing a copy of copyrighted works illegal, then proxy servers etc... would be technically in breach of that law
20:11:26 <Halcyon> Not to say legislation won't ever catch up, it probably will, but for the time being, we're safe
20:11:39 <hsn993> so downloading movies from piratebay is legal but dont watch or distripute them ?
20:12:06 <Ysjoelfir> If i understood it correctly, even watching is legal. but not distributing it
20:14:09 <Ysjoelfir> let us just all migrate to australia, the laws seem to be pretty good there :D
20:15:45 <mamalala> what? so we all have to walk on our heads?
20:16:07 <mamalala> ... and have kangaroos kick us in the nuts?

20:16:46 <Halcyon> hsn993: You can watch them
20:17:23 <hsn993> legal ?
20:17:34 Nick: hsn993 is now known as hsn
20:17:43 <Halcyon> In most countries where you start treading into unlawful territory is when you make, distribute, sell or exhibit copies without authorisation
20:17:50 <Halcyon> Of course I only know Australia law
20:18:12 <Halcyon> Mere downloading may very well be illegal where you are, I have no idea
20:18:53 <hsn> i dont know about here law but every computer shop is installing cracked windows version for ($10) maybe xD
20:18:54 <Halcyon> Importation of infringing copies is also illegal here, however that relates to physical goods such as counterfeit products, movies etc...
20:19:16 <Halcyon> Sounds dodgy ;-)
20:19:20 <hsn> they include office in that image also
20:19:22 <hsn> lol
20:19:34 <Halcyon> I wouldn't trust that image with a barge pole
20:19:35 <hsn> one time i saw goverment pcs having cracked windows
20:19:49 <Halcyon> Oh gees
20:20:04 <Halcyon> I mean, Windows 10 is utter garbage, it's probably only worth $10
20:20:20 <Ysjoelfir> but.. why? you can get legal win7 for 8€ and still update that for free to win10^^
20:20:30 <hsn> does installing it worth $10
20:20:32 <hsn> :P
20:20:33 <Halcyon> Do they still offer free updates?
20:20:41 Join: qeed ([email protected]) to #EEVblog
20:20:41 <Ysjoelfir> not officially, but yes. it still works
20:20:41 <Halcyon> I thought Microsoft stopped that
20:20:56 <hsn> no they are generous
20:20:57 <Halcyon> If you have Windows 7, not sure why you would want to "update" to Windows 10
20:20:58 <Ysjoelfir> I just used it... lets say... 4 weeks ago
20:21:10 <Ysjoelfir> erm... because.
20:21:59 <hsn> you can get legal win7 for 8€ ----> ?? where
20:22:27 <mamalala> hsn: depends on where you are
20:22:39 <Ysjoelfir> https://www.mmoga.de/Software/Windows/Windows-7-Professional-32-64-Bit.html
20:22:44 <Ysjoelfir> 4,99€
20:22:48 <Halcyon> You can still buy leftover stock of Windows 7 OEM from some places here
20:22:58 <mamalala> here in germany it is legal to re-sell unbundled oem licenses... and as such, you can buy windows keys for next to nothing on ebay
20:23:54 <hsn> i probably bought 3 laptops and paid for windows that included with them
20:23:55 <Ysjoelfir> what mamalala says. BUT: don't try that with office. My employer bought... I would say, 200 copies of that for 2,99€ each. all suddenly expired as microsoft was like "meh, I don't like that"
20:24:07 <Halcyon> Hahaha
20:24:11 <mamalala> also, shrink-wrap licences are null and void here in krautland... that is, any software you buy, where you can read the license only after opening the package, that license is void
20:24:17 <hsn> now i dont own the key of that laptop does that give me right to use pirated windows ?
20:24:23 <Halcyon> Why would you bother when LibreOffice and OpenOffice are both free?
20:24:23 <hsn> xD
20:24:37 <mamalala> Ysjoelfir: you can do the phone activation... typing numbers to a robot
20:24:53 <mamalala> Halcyon: indeed
20:24:57 <hsn> Halcyon i love open source but lets be honest both are nothing compared to ms office
20:25:22 <Ysjoelfir> compatibility still isn't perfect halcyon. many of the customers can't read .ods and exported .xls or even .xlsx are sometimes dodgy.
20:25:26 <mamalala> hsn: how so? i mean, realistically, what do you use it for?
20:25:49 <Ysjoelfir> and the phone activation didn't work mamalala. sadly.
20:26:02 <Halcyon> hsn: I disagree, I use LibreOffice for everything now but forced to use Office 365 at work. It's garbage.
20:26:12 <mamalala> Ysjoelfir: yea, but the "reading .ods" part is just because microsoft doesn't want to ... after all, not only is the format open, but the implementations as well
20:26:16 <Halcyon> Honestly, give it a try
20:26:28 <Ysjoelfir> i absolutely agree.
20:26:40 <hsn> i tried it before on my laptop didnt like the interface to much
20:26:43 <Halcyon> Office has supported ODS for some time. It's 99.5% perfect.
20:26:44 <hsn> excel ^
20:26:55 <hsn> my laptop has ubuntu
20:27:05 <Ysjoelfir> I personally use my ancient office 2k3 at home, just because I have it. If I wouldn't have that, I would use libre.
20:27:06 <mamalala> and the other way around, reading ms-office stuff in libre/openoffice is buggy because microsoft decided to play silly games and not abide by the specs
20:27:17 <Halcyon> Yep
20:27:34 <Halcyon> But who cares? Stick to an open standard and you won't have dramas.
20:27:36 <mamalala> Halcyon: shall i send you some spreadsheets of mine that have plots in them, which don't render?
20:27:41 <Halcyon> Anything to clients is generally PDF
20:27:51 <Halcyon> Sure, I'd like to see how it goes
20:28:07 <mamalala> funny enough, opening ms-office into libreoffice works, still getting the graphs
20:28:48 <mamalala> Halcyon: http://atelier-klippel.de/Report2020/IWTO-0_Trapeziums.ods
20:29:12 <mamalala> the main gist with plots as pdf: Halcyon: http://atelier-klippel.de/Report2020/IWTO-0_Trapeziums.pdf
20:29:19 <Halcyon> Do I need to run the Macros?
20:29:23 <mamalala> no
20:29:33 <mamalala> that macro is just because of a libre-office quirk
20:29:46 <hsn> next time i need to install office i will go for libre
20:29:48 <mamalala> that is: you change the data cells, but the graph doesn't update
20:30:02 <mamalala> but if you mive the graph a bit, and then undo the move, it is updated

20:30:28 <mamalala> so all the macro does is to traverse all the sheets, nudge the graphs to update them
20:31:02 <mamalala> Halcyon: well, yes, because you are in libreoffice :P
20:31:07 <Halcyon> Yes
20:31:07 <Halcyon> :)
20:31:10 <mamalala> try to open it in ms-office
20:31:23 <mamalala> then the graphs will be empty
20:31:24 <Halcyon> I don't use MS Office :P
20:31:26 <hsn> i would want to see the ribbon toolbar

20:31:49 <mamalala> Halcyon: ah, ok, i misunderstood then... i thought you wanted to try opening them in ms-office
20:31:54 <Ysjoelfir> "Excel found unreadyble items in the file. Do you want to repair the spreadsheet?" :D

20:33:48 <Halcyon> I completely ditched Windows about 12 months ago.
20:33:54 <Ysjoelfir> https://snipboard.io/JqaEmK.jpg
20:34:05 <mamalala> especially since they are not static, but their entries change with whatever you used in the past
20:34:18 <Halcyon> Before then, I had been a Windows guy (both desktop and server) since forever
20:34:30 <Halcyon> I grew up on MS-DOS and Windows 3.1
20:34:36 <mamalala> Ysjoelfir: ha, yes...
20:34:38 <hsn> what u mean they are not static ?
20:34:42 <Ysjoelfir> excel 2010 ;)
20:34:46 <hsn> they are always in same place
20:35:16 <mamalala> hsn: some entries change the default behaviour when you click them .. stuff like line-style, colour, etc... depending on what you used before
20:35:39 <hsn> but that what i want usually ^
20:35:40 <mamalala> Ysjoelfir: it's not better on the newest office version either
20:35:47 <hsn> to color the last color
20:35:55 <Ysjoelfir> I assume that
20:36:07 <mamalala> hsn: well, that's what your standard icons will do as well in, for example, libre-office
20:36:26 <mamalala> ...with much less screen-clutter
20:36:53 <mamalala> Halcyon: hope you are happy with linux so far
20:36:56 <hsn> ok i will try libre office in my laptop and will tell u what i miss here and there
20:37:01 <Halcyon> Yep love it
20:37:06 <Halcyon> I run MX Linux
20:37:14 <mamalala> worked just fine for me the past 15+ years
20:37:23 <Halcyon> I mean it hasn't been smooth sailing, had issues along the way, but it's a learning curve
20:37:34 <Halcyon> Still, beats the hell out of Windows 10's many issues
20:37:48 <mamalala> Halcyon: indeed... but that's always the case if you switch operating systems
20:38:09 <Halcyon> Of course
20:38:19 <Halcyon> But I love the simplicity but also the complexity
20:38:25 <mamalala> heck, i mean, just look at what the windows control panel does after every update ... stuff is suddenly not where it was before... with each major win update
20:38:42 <mamalala> Halcyon: have you discovered shell pipelining yet?
20:38:43 <Halcyon> If only everything was in Control Panel!
20:38:50 <Halcyon> They have scattered settings everywhere
20:39:06 <Halcyon> Why do I need two separate places to uninstall software in Windows?
20:39:17 <Halcyon> Yep, I understand piping etc...
20:39:41 <mamalala> if it would even uninstall completely ... usually you are still left with a lot of crud in the registry
20:40:21 <Halcyon> That has always been an issue with Windows
20:41:31 <Halcyon> I feel as though Microsoft have tried to make Windows 8/10 too much like Apple but ended up with an unpolished and bodged together mess
20:41:45 <Halcyon> They've even dumbed down the language for idiot users
20:42:13 <mamalala> well, to some extent, yes
20:42:14 <Halcyon> BSOD's have huge :( smileys and shit like "Apps" is everywhere
20:42:32 <hsn> tbh its much better than 5 years ago
20:42:37 <mamalala> and let's not even talk about the silly app stuff that runs in the start menu, and all that shit...
20:42:37 <Halcyon> No way
20:42:42 <Halcyon> Windows 7 was excellent
20:42:46 <hsn> i cant find (freeze columns)
20:42:46 <Halcyon> And much faster too
20:42:54 <hsn> not (first column / first row)
20:43:02 <hsn> in libre office
20:43:17 <hsn> tried both menu (view > freeze cells) and the icons
20:43:51 <mamalala> what do you mean by "freeze"? that the user can't change the contents?
20:44:32 <hsn> no .. just the header
20:44:35 <hsn> when u scroll
20:44:38 <hsn> it sticks
20:45:07 Quit: JoePublic ([email protected]) Quit: http://www.kiwiirc.com/ - A hand crafted IRC client
20:45:08 <Halcyon> HSN: Click the "Split" button, drag them where you want, then go to View > Freeze Columns and Rows
20:45:52 <hsn> aaah nice
20:46:52 <hsn> its pretty nice actually
20:46:57 <Halcyon> Some things you need to consult the help/Google for, but for the most part, things are in logical places
20:47:06 <Halcyon> It is a little different to MS Office, but I prefer it
20:47:11 <mamalala> yay! working on stupid spreadsheets for over 30 hours now.... time to go to the supermarket and get some beer... need to start numbing down my brain, otherwise i'll go insane ...
20:47:27 <mamalala> back in a few minutes...
20:47:31 <Halcyon> mamalala: I've got the wine open :)
20:48:05 <Halcyon> LibreOffice reminds of of Office 2003/2007, and I loved them
20:48:13 <Halcyon> Uncluttered
20:50:50 <hsn> Sampling Rate: 2GSa/s ////// Bandwidth: 200MHz ---------------> when i've bandwidth of 200MHz does that mean i cant measure 201MHz ?
20:51:18 <hsn> or it means that it will just have attenuation (some -dB gain)?
20:51:56 <hsn> because 2GSa/s ----> can measure 1GHz right?
20:53:43 <Ysjoelfir> Usually it means that you have at 200MHz a drop of 3dB in amplitude
20:54:42 <hsn> right,, but u can still measure 400MHz with 200Mhz scope ? just (lower magnitude) ?
20:55:57 <Ysjoelfir> well... you cant say that since every scope is different. you can, however, assume that frequencies over the bandwith limit can be displayed, but with an unspecified error. How far out of the BW limit you can go depends again on the scope and the signal form

20:58:02 <K> hello
20:58:06 <Ysjoelfir> hello K
20:58:07 <EEVBlog> Hello there, Ysjoelfir!
20:58:15 <Ysjoelfir> woohoo! now It's me that it likes!
20:58:20 <hsn93> then why do i need to look at (sampling rate) of digitizers?
20:58:25 <hsn93> Hello K
20:58:32 <hsn93> :(
20:58:48 <Ysjoelfir> na, it won't trigger on you. it's been programmed by a kraut, so it is a racist bot. :P
20:59:21 <hsn93> EEVBlog time
20:59:22 <EEVBlog> Ah shoot, Doc! We've ended up at 20:59 Sydney time.
20:59:30 <hsn93> at least it replies the time
20:59:45 <Ysjoelfir> hehe
21:00:50 <Ysjoelfir> regarding the smaple rate: you can't really relate bandwidth and sample rate. the bandwith tells you how "fast" of a signal the analog input circuitry can manage, while the sampling rate tells you something about the digital part and how fast it acquires the samples from the ADC.

21:01:53 <Halcyon> Hahaha
21:02:25 <Halcyon> Ahh looks like Dave is coming up my way tomorrow
21:02:34 <Ysjoelfir> is he?
21:02:45 <Halcyon> Yeh he comes up here to the mountains to go canyoning
21:03:14 <T3sl41> canyonerrooooooooooooooooooooowooh
21:03:28 <Ysjoelfir> ah. don't know much about canyons or mountains
21:03:34 <Ysjoelfir> especially in down under
21:03:46 <Halcyon> I live here but that's as far as I know
21:03:49 <Halcyon> I don't do any of that stuff
21:04:29 <mamalala> jeezus fucking christ on a stick ... what are all these people doing in the supermarket at this time... don't they have jobs or something? :P
21:04:58 <Halcyon> What time is it?
21:05:04 <Ysjoelfir> 11
21:05:11 <K> they are bying supplies because of covid
21:05:36 <mamalala> hsn93: on a digital scope, with well implemented digital filters, on 200MHz and meassuring 201MHz usually results in a 1MHz readout (foldback due to nyquist)
21:05:39 <Ysjoelfir> And yeah... I know that problem. especially old people seem to be shopping around that time like they will die this evening
21:05:46 <Halcyon> K: What kind of supplies?
21:05:50 <Halcyon> Seems silly to me
21:06:00 <K> non perishable food
21:06:03 <mamalala> Ysjoelfir: haha, yea ... man, when i lived in munich, it was crazy for the bus
21:06:09 <Halcyon> OK ?
21:06:10 <K> in case everything gets locked down china-style
21:06:20 <Halcyon> Riiiight
21:06:26 <K> (im just arsing around, don't mind me)
21:06:50 <mamalala> you can see old people running after the bus, just to catch it ... and when inside, they instantly put on a sad, fragile look meant to make you feel bad if you are not giving up your seat for them
21:06:51 <Ysjoelfir> what is covid? is that this new virus thing we call corona here?
21:07:04 <Ysjoelfir> exactly mamalala!
21:07:13 <K> how much to eat you have in your house if shops/eateries are closed?
21:07:33 <Halcyon> Ysjoelfir: Yes, it's been renamed
21:07:44 <mamalala> i mean, really, you old fuck? you just managed to put on a 50m sprint that is worthy of a world record, but now you pretend to be barely able to mive?
21:07:45 <Halcyon> It's called COVID-19
21:07:48 <mamalala> *move
21:08:17 <K> the clockspring is unwound
21:08:31 <Ysjoelfir> once one of said species started to argue with me. when I told her that I have a bad back and can't stand for long she screamed all over the bus, the yoputh of today, iompossible, how sad it is, bla...
21:08:32 <mamalala> K: enough for a few days... but i just bought beer, and that i always buy "on demand"... because if would try to stock it, i would be drunk all day...
21:08:44 <Ysjoelfir> why did they have to rename that thing?
21:09:01 <K> because "coronavirus" is a generic name for a family of viruses
21:09:15 <Ysjoelfir> ooh, ok. that makes sence then
21:09:39 <K> "covid-19" is for this instance
21:09:42 <hsn93> mamalala, so BW should always be turned ?
21:10:25 <hsn93> we've got some pharmacies closed because they hide masks and tried to raise the price xD
21:11:03 <hsn93> people wearing masks looks stupid tbh .. its not like we have somthing that serious ..
21:12:15 <mamalala> hsn93: on a digital scope, you have two kinds of bandwidth
21:12:30 <mamalala> one is the analogue front-end, the other is the digital processing
21:13:30 <hsn93> yeah.. but if you tell me (201MHz) might be displayed as (1MHz) its so scary that makes me to say (always turn BW on -> i assume BW = cutout 200MHz) ..
21:14:08 <mamalala> hsn93: the analogue front end doesn't care much ... at worst, the signal is attenuated... but the digital processing stage may fold back
21:14:31 <Ysjoelfir> exactly. :)
21:14:45 <hsn93> yes understood
21:14:51 <mamalala> also, there is a reason why bandwidth can be selected... if you have slow signals, but meassure them at high bandwidth, you may get "false" reading/effects
21:15:17 <mamalala> especially noise usually goes way up if you sample at high bandwidth
21:16:38 <Ysjoelfir> (which is a reason why I like my good old Tek 502A)
21:16:54 <mamalala> i think dave made a video about that exact topic quite some time ago
21:17:18 <mamalala> digital scopes are somewhat tricky to use... you really need to know what you are doing... analogue scopes are somewhat easier in that regard
21:18:37 <hsn93> and what cirumistances u need to turn BW off ?
21:19:03 <T3sl41> normally set it to 20 or 100MHz BW when the signal is annoyingly noisy or spiky
21:19:58 <K> (insert three monkeys picture)
21:22:11 <Ysjoelfir> K, look! A three headed monkey! *immitates guybrush threepwood voice*
21:22:42 <mamalala> ha! good old adventure games
21:23:06 <Ysjoelfir> hehe
21:23:06 <mamalala> the sweet, sweet point&click stuff :)
21:23:12 * T3sl41 bops Ysjoelfir with a stick from a rubber tree
21:23:56 * Ysjoelfir puts some lice on the comb the pirate barber uses on T3sl41s hair
21:24:12 * T3sl41 seeps good
21:25:06 Nick: T3sl41 is now known as T3sl4
21:25:19 <Halcyon> :)
21:25:28 * mamalala can't decide ... do more spreadsheets/statistics, or get silly drunk
21:25:44 <mamalala> although, the latter may help with the former
21:25:58 <Halcyon> Clearly the latter
21:26:15 <Halcyon> There is a window of opportunity to do the former whilst you're getting drunk :)
21:26:43 <Ysjoelfir> oh, Halcyon! Did I tell you that Lemon brought me a bottle of french wine?
21:27:21 <Halcyon> No, you didn't
21:27:25 <Halcyon> What kind of wine did you get?
21:27:39 <Ysjoelfir> He told me to let it sit for a while since it was very recently bottled. It now sits there, on the kitchen counter, waiting for me to open it.
21:27:40 <Ysjoelfir> erm
21:27:53 <Halcyon> Cork or screw cap?
21:27:57 <Ysjoelfir> don't ask me what it is, ask lemon :D it's.. wine. and it is supposed to be good.
21:28:20 <Ysjoelfir> I can look that up when I'm home, but IIRC its a cork
21:28:34 <Halcyon> Keep it on it's side then
21:28:52 <Halcyon> If the wine isn't in contact with the cork, it dries out, shrinks and lets air in
21:29:08 <Ysjoelfir> oh, ok :)
21:29:17 <Halcyon> And air = bad when it comes to wine
21:29:20 <mamalala> Ysjoelfir: he brought me some drink as well ... also told me to let the wine sit for a few days... but then i decided to not give a fuck and drink it
21:29:26 <mamalala> it was _very_ tasty
21:29:30 <Ysjoelfir> XD
21:29:38 <Halcyon> If it was recently bottled and it's a red, might be worth keeping a few years
21:29:41 <mamalala> i mean, usually i don't like wine ... but that one was really, really good
21:29:53 <T3sl4> Halcyon: it is.... it is wine https://www.youtube.com/watch?v=r0RuRJOQa8M
21:29:56 <Halcyon> Or just drink it :P
21:31:06 <Halcyon> mamalala: What wine was it?
21:31:28 <mamalala> http://atelier-klippel.de/20200227_113029.jpg
21:32:01 <Ysjoelfir> ah yes, I think it's the same :)
21:32:19 <mamalala> it's really good
21:32:37 <hsn93> ah BW is actually 20MHz not 200MHz ..
21:32:41 <mamalala> well, compared to the cheap stuff you get in the supermarket, anyways
21:32:57 <mamalala> but then, as said, i'm not a wine guy, and this one was the best i had so far

21:33:30 <Lemon> hello !
21:33:38 <hsn93> hi lemonish
21:33:47 <Halcyon> Looks like a blend
21:33:52 <Halcyon> I have no idea how to read that
21:34:00 <Ysjoelfir> It's french, don't bother
21:34:06 <Ysjoelfir> french is known to be unreadable
21:34:08 <Lemon> wats french
21:34:10 <Lemon> wats french
21:34:16 <Ysjoelfir> except from a small group of strange person
21:34:34 <Lemon> lemme offer my free translation program
21:34:47 <Halcyon> Lemon: The wine you left the boys
21:34:50 <Lemon> where you give me things and I puke them in a readable form
21:34:51 <Halcyon> What kind of wine is it?
21:35:00 <T3sl4> https://www.youtube.com/watch?v=pwODwwgE6rA
21:35:14 <Halcyon> Hahaha
21:35:19 <Ysjoelfir> lol :D
21:35:24 <Lemon> its a Gamay, made in oak barrels :> which a local family makes
21:35:26 <mamalala> Lemon: ha, just talked about the tasty wine you brought us
21:35:35 <Lemon> its kinda light I really like it
21:35:41 <mamalala> Lemon: http://atelier-klippel.de/20200227_113029.jpg
21:35:45 <Halcyon> What kind of grape?
21:35:55 <Lemon> thats a good question xD
21:36:07 <mamalala> sadly the bottle was empty even before you left ... must have had a hole in the bottom, or something
21:36:13 <Halcyon> Since nothing stands out on the label, I'm guessing it's some kind of non-vintage blend?
21:36:18 <Lemon> thats Gamay :>
21:36:26 <mamalala> probably evaporated over night because of the excessive heat here in germany ... haha
21:36:26 <Lemon> the type of grape is named like that
21:36:38 <Halcyon> Oh right
21:37:22 <Halcyon> Judging what I read it would be perhaps comparable to our Pinot Noir ?
21:37:44 <mamalala> Halcyon: it's comparable to "tasty"
21:37:46 <Halcyon> Hahah

21:44:56 <mamalala> Lemonizer: can't see anything from you on the /query, in case you replied there
21:45:08 <Halcyon> They do an episode in France which is among the best
21:45:59 <Halcyon> The start of it is in that link at the start
21:45:59 <Ysjoelfir> things that include the word combination of "France" and "best" somehow seem wrong to me :P
21:47:17 <mamalala> Halcyon: that series is not politically correct! you racists mysoginist pig, you!!! :P
21:47:25 <Halcyon> :P
21:47:30 <Halcyon> It's brilliant
21:47:40 <mamalala> yea, british humour often is
21:47:44 <Halcyon> Just like Hogan's Heroes is brilliant
21:48:02 <mamalala> but the kangaroo-shaggers have some good humour as well, i must say
21:48:20 <Halcyon> This is where they go wine tasting in France: https://youtu.be/Jar7Pk0OCR4?t=163
21:48:37 <mamalala> Halcyon: https://www.youtube.com/watch?v=3m5qxZm_JqM
21:48:58 <mamalala> clarke & dawe are great ... and it's in down-under, imagine that
21:49:09 <Halcyon> Hahah
21:49:18 <Halcyon> We have plenty of series' like that
21:49:29 <Halcyon> All the good stuff was made in the 1990's
21:49:53 <mamalala> Halcyon: ah, so you are from the other side of the flat earth, then?
21:50:02 <Halcyon> mamalala: Sydney
21:50:07 <Halcyon> I know Dave personally
21:50:22 <mamalala> Halcyon: hope you didn't have any troubles due to the nasty fires over there
21:50:25 <Halcyon> Hence why I'm here :)
21:50:38 <Halcyon> Eh, we survived
21:50:52 <mamalala> pretty scary stuff, i must say
21:51:00 <Halcyon> You might enjoy this: https://www.youtube.com/watch?v=YR80tnIz5r4
21:51:04 <Halcyon> This is one such sketch show
21:51:10 <Lemonizer> but yeah to talk more about the local wine producer, called Jean Marie Guelle, is one of the last that makes good wine without modifying too much
21:51:37 <mamalala> Halcyon: abba? are you kidding me? :P
21:51:38 <Lemonizer> he makes red wine, 'rose', white, some with bubbles I never know the english name
21:51:44 <Halcyon> Give it a try
21:51:50 <Lemonizer> with various light flavours which is surprinsingly good
21:51:59 <mamalala> my precious let bandwidth...
21:52:03 <mamalala> *lte
21:52:44 <Ysjoelfir> you make it hard for me to not open it this evening, lemon^^
21:52:53 <mamalala> ahh, seems to be a parody
21:52:59 <Halcyon> Do it Ysjoelfir
21:53:09 <mamalala> Ysjoelfir: do it! it's good!
21:53:11 <Halcyon> mamalala: Fast Forward was a parody sketch show
21:53:13 <Ysjoelfir> but he told me to let it sit for a while^^
21:53:18 <Lemonizer> haha :p well sometimes I drink them right away, its still good but it earns to wait a bit x)
21:53:23 <mamalala> Halcyon: ahh, didn't know that
21:53:39 <Lemonizer> I have told you to wait ! :P
21:53:41 <mamalala> Ysjoelfir: well, it has been a few days now, so that counts as "a while"
21:54:01 <Halcyon> For example: https://youtu.be/dqxaeAjUDz0?t=97
21:54:01 <Lemonizer> but well honestly its still good, just keep in mind that local wine isnt modified as much
21:54:09 <Lemonizer> so sometimes you can get a bottle thats less good
21:54:50 <mamalala> Lemonizer: can you try to /query me? because i'm getting nothing so far
21:55:24 <Lemonizer> have you tried to quit and login in again ?
21:55:27 <Lemonizer> theres some kind of issues
21:55:41 <mamalala> Halcyon: hmm, not my style, i'm afraid
21:55:54 <Halcyon> Fair enough

21:58:45 <mamalala> Lemonizer: i don't see yours, though ... strange ... guess i'll shoot you an email then
21:59:27 <Halcyon> mamalala: If you understand Aussie politics I would have the perfect show for you
22:00:09 <Halcyon> https://iview.abc.net.au/show/shaun-micallef-s-mad-as-hell
22:00:10 <mamalala> Halcyon: meh, no idea about .au politics ... heck, i even barely know .de politics
22:01:07 <Halcyon> I'm actually going to go watch an episode, I have lots to catch up on
22:02:35 <mamalala> all i know about .au politics is that they are starting to fall for the same PC shit as everyone else
22:04:51 <mamalala> Halcyon: pff... doesn't let me play it ... only get a black screen when i click on the video
22:05:15 <mamalala> stupid people that haven't understood what _inter_net actually means
22:13:52 <Ysjoelfir> woohoo!
22:13:57 <Ysjoelfir> T3sl4, still here?^^
22:14:17 * T3sl4 meows
22:14:49 * Halcyon puts the cat out
22:14:58 <Ysjoelfir> I applied for that App note writing job thing, more for fun than anything serious. They seem to like me.
22:15:06 <mamalala> hey, leave the kitty alone!
22:16:06 <T3sl4> heh
22:16:13 * T3sl4 scratches at Halcyon
22:16:22 <Halcyon> :P
22:16:38 <Ysjoelfir> let's see if I can increase the niveau of their appnotes xD
22:18:50 <Ysjoelfir> It would be for "dialog semiconductor".
22:19:13 <T3sl4> ah
22:26:38 <hsn93> i've goot square wave 1KHz from oscilliscope generated for compensating the probe, i connect it to probe and set the channel input to 50Ohm .. probe set to 1x .. the channel is set to AC coupling ..
22:27:05 <hsn93> Vrms = 57mV ,, Vpp = 124mV
22:27:33 Join: steve30 ([email protected]) to #EEVblog
22:27:46 * Ampera coughs at Halcyon
22:28:01 <hsn93> oh right Vrms = Vpk in square wave
22:28:13 <T3sl4> so, shorting out the probe?
22:28:23 <hsn93> why shorting ?
22:28:29 <steve30> hmm, cpc cancelled my raspberry pi
22:28:42 <Ampera> steve30, shipping from china?
22:28:55 <T3sl4> probe only probes when it's connected to 1M || 20pF or whatever
22:28:57 <hsn93> cpc ->
22:29:05 <T3sl4> surprised you get that much out of it at 50R
22:29:26 <T3sl4> i suppose it'll be actually nil on 10x, while on 1x the probe is something like 300R in series
22:29:43 <hsn93> so probe is actually ac coupled 20pF?
22:30:01 <hsn93> with dc 1M oh ok
22:30:15 <hsn93> no its 1x
22:30:41 <T3sl4> which, come to think of it, lemme see... one of my probes here is 251.2 ohms at 1x (from probe tip to connector pin)
22:31:25 <hsn93> when u have 1x ,, do you remove the cap or the 1M ?
22:31:52 <hsn93> i mean when the probe set to 1x .. is it still (1M || 20pF) ?
22:31:53 <T3sl4> the cap is the scope dude
22:32:05 <T3sl4> or it would be if you hadn't switched it to 50R
22:32:08 <Halcyon> Hey Ampera :)
22:32:18 <Ampera> how are you doing Halcyon
22:32:23 <Halcyon> Sleepy
22:32:24 <Halcyon> You?
22:32:25 <mamalala> someone surely needs to learn some basics about scopes, givent the recent questions/issues
22:32:42 <Ampera> sleepy, need to take a bath, and then go to work
22:32:47 <Halcyon> Hot
22:32:56 <Ampera> no it's quite cold over here
22:33:02 <Halcyon> I mean the bath :P
22:33:07 <Ampera> in the 30's today
22:33:32 <Ampera> or rather lower single digits, and freezing throughout the night
22:33:45 * Ysjoelfir goes out for lunch
22:33:52 <Ampera> freezing all day tomorrow
22:35:12 <hsn93> T3sl4 so 10x = 1M ,,, 1x = 0ohm ?
22:36:08 <hsn93> agh , its actually 9M
22:36:43 <steve30> Ampera, no, local supplier. Looks like its not in stock.
22:36:56 <T3sl4> the probe equivalent circuit is R || (R+C) into a cable in 10x, or straight into the cable (1x)
22:36:57 <Ampera> perhaps then an issue down the line
22:37:11 <T3sl4> where the R is 10M and the R+C is maybe 1k + 6pF
22:37:18 <Ampera> Pine64 is out of stock and barely shipping a bunch of stuff, which is sad
22:37:19 <T3sl4> well, 9M*
22:37:41 * steve30 hugs Halcyon
22:37:54 <Halcyon> :D
22:38:05 * steve30 is making curry
22:38:10 <Halcyon> Oh yum
22:38:19 <mamalala> Ampera: you need an ARM board? i may have one to give away
22:38:29 <Ampera> I'd like one of the pbpros
22:38:41 * T3sl4 plops a few chopped cabbage leaves into steve30's curry
22:38:48 <Ampera> as for ARM boards, I have three Pis I'm not using. I'm never one to say no to free shit, but other people might benefit more
22:39:01 <hsn93> ok 1x is shorted and in the scope its 50ohm ... droped to 120mV .. why u suspect it will much lower ?
22:39:15 <T3sl4> hsn93: you use the probe with the scope always on 1M setting
22:39:30 <Halcyon> I'm off to bed, night all
22:39:34 <T3sl4> you use 50R with cables and matched impedance signals, low-Z probes, that sort of thing
22:39:38 <Halcyon> eevblog time
22:39:38 <EEVBlog> Ah shoot, Doc! We've ended up at 22:39 Sydney time.
22:39:43 * T3sl4 slaps Halcyon on the cheek on his way out
22:40:49 <mamalala> Ampera: one is a Nano-Pi M1, the other is a ODroid C2, and also a Nano-Pi NEO
22:41:19 <mamalala> somewhere i have yet another one that has an SATA interface, just can't fine it somehow
22:42:03 <mamalala> even have two of the NEO's and M1's to spare
22:42:09 <Ampera> I have a Pi B, Pi 2B, and a Pi 3B, and enough PCs to go around
22:42:26 <Ampera> Are you looking to get rid of all of them for some reason?
22:43:06 <mamalala> not really, just mentioning it because i thought you needed one
22:43:10 <Ampera> nah
22:43:18 <Ampera> keep them, you likely have better use
22:43:38 <mamalala> they sure make nice dust collectors :P
22:44:13 <mamalala> https://cheezburger.com/9446373888/painfully-accurate
22:44:14 <mamalala> haha
22:44:40 <Ampera> They're the sort of thing you wire up, throw linux on, and then say
22:44:41 <Ampera> well now what
22:44:49 <Ampera> it does everything my PC can do and less, and my PC is right over here
22:45:02 <hsn93> T3sl4 thanks
22:45:19 <T3sl4> welcome :)
22:45:41 <mamalala> yea... i just like to play with them from time to time, see how stuff is progressing on that front ... lot's of vendors are still crap when it comes to drivers for their chips
22:46:11 <Ampera> I also bought a PineTime, which I will need the pi to program
22:46:19 <Ampera> but I don't know when that will ship out
22:50:07 <hsn93> and i got with 1x probe (Vrms = 1.48V) << 3v3 pk-pk .. when i do the scope fft i got (2.64dBVrms) .. i did math of (2.64dBVrms -> it should be 1.356Vrms)
22:51:44 <hsn93> in the manual i can see : BW Flatness at BNC
22:51:44 <hsn93> input :: DC -10% of rated BW: +/- 1dB
22:52:02 <T3sl4> hsn93: fundamental amplitude?
22:52:15 <hsn93> does that mean my FFT has error of +/- 1dB ...
22:52:30 <mamalala> "at BNC" is one keyword here
22:52:44 <mamalala> add a probe inbetween, and it will be different
22:54:51 <hsn93> T3sl4, i would say fundamental amp = 3v3 ,, ac coupled = 1.65V
22:55:37 <T3sl4> no, what did you measure in the fft
22:55:43 <T3sl4> just the fundamental, or the whole thing?
22:56:27 <hsn93> the foundamental (ie 1Khz)
22:56:55 <T3sl4> then there's a pi/sqrt(2) you're missing
22:57:53 <T3sl4> sqrt(8) rather
22:58:42 <Lemonizer> idk how to do with that Vref
22:58:50 <Lemonizer> charging batt everyday will piss me up
22:59:25 <Lemonizer> I have a cheap lab smpsu that I could dedicate but idk if its suitable due to its high noise
22:59:55 <hsn93> oh so dBvrms of the fundamental 1Khz (not as square wave)
22:59:58 <mamalala> add a cut-off circuit to the ref, which switches off after a certain charge level is reached... then keep it plugged into a trickle charge all the time
23:00:26 <mamalala> the cutt-off should also switch off when the charge is too low
23:00:47 <mamalala> there should be plenty of ready-made and cheap circuits for that out there..
23:00:55 <Lemonizer> yeah I could do that
23:02:35 <hsn93> T3sl4, where im missing (pi/sqrt(2)) ?
23:02:59 <T3sl4> https://en.wikipedia.org/wiki/Square_wave#Fourier_analysis
23:03:18 <Lemonizer> I also need to figure the voltage needed for that nice resistance bridge
23:03:28 <Lemonizer> it needs two types of unknown batteries
23:03:33 <Lemonizer> and theres no info on the net
23:04:10 <mamalala> a resistance bridge that needs bateeries?
23:04:21 <mamalala> *batteries
23:04:28 <Lemonizer> https://imgur.com/a/MZzcTqn
23:04:31 <Lemonizer> the last picture
23:05:23 <mamalala> ahhh, so it's more like an ohm-meter with (literally) manual ranging and stuff
23:05:43 <Lemonizer> I think its made to compare two resistors precisely
23:06:06 <mamalala> what i consider a resistor bridge is a box where you can dial in a desired resistance, and it will present as such on the connectors
23:06:20 <hsn93> T3sl4, from the wikipedia link ... u mean im missing 4/pi instead of (pi/sqrt(2))?
23:06:32 <Lemonizer> a decade box no ?
23:06:33 <mamalala> seems to compare against internal resistors
23:06:49 <T3sl4> yes, except one more thing, the formula is peak not RMS
23:06:52 <mamalala> well, a decade box is basically the same, but for decades
23:07:12 <Lemonizer> I need one of those
23:07:24 <Lemonizer> a dude was selling small boxes that could fit together
23:07:29 <mamalala> a true bridge allows you to set the resistance in small steps, so you can have a somewhat arbitrary value
23:07:38 <Lemonizer> AIOP branded (france) with like 0.2% tolerance or so
23:07:47 <mamalala> you can find proper units for cheap on eBay sometimes
23:08:13 <Lemonizer> but yeah this device could help me match resistors for a KVD or a hammon divider
23:08:17 <mamalala> usually 19" units with lots of dials on the front, where you can set each "digit" of the desired resistance
23:08:35 <mamalala> do you have any pics of the battery compartment of that device?
23:09:38 <Lemonizer> ha no, it looks like one for a double pole battery like 9 volts, but its not
23:09:47 <Lemonizer> and one with single pole like AA or so
23:09:51 <mamalala> take a pic, please
23:10:06 <Lemonizer> sure gimme a sec
23:13:57 <Lemonizer> https://imgur.com/a/ExrtBwP
23:14:07 <Lemonizer> just noticed the second pic is shit, but the first sould be enough
23:14:27 <mamalala> back in the days it was not uncommon that battery cells went into a holder, which in turn was put in the device
23:15:10 <Lemonizer> I have no idea what are those really
23:15:13 <mamalala> ok ... i guess the red wire at the bottom in the first pic also has a clip?
23:15:16 <Lemonizer> at first looked like 9v but no
23:15:31 <Lemonizer> yes
23:15:42 <Lemonizer> it says a big and a small battery on the top of the device
23:16:10 <mamalala> https://circuit.direct/products/battery-holder-for-4-aa-batteries-with-9-v-type-battery-clip-258-814
23:16:17 <mamalala> maybe something similar to that...
23:16:22 <mamalala> just a different cell count
23:16:28 <Ysjoelfir> Aaaah, I got back just in time :) Now you see why I said I never tried it :)
23:16:37 <Lemonizer> haaa yes could be
23:16:42 <mamalala> some of those holders also have extra "taps"
23:17:04 <mamalala> i guess the box has no active electronics in it?
23:17:17 <Lemonizer> 'replace large batterieS and small battery'
23:17:25 <Lemonizer> hmm no seems only to be resistors
23:17:28 <Lemonizer> ho wait
23:17:48 <mamalala> or if it does, i guess that a 3-clip set is for a +/- volatge for the amplifiers, and a 2-clip set is for the test voltage
23:18:26 <mamalala> but then, you can send it together with the crate of that fine wine, i'll figure it out then, and send it back with instructions :P
23:18:33 <Lemonizer> ML709CT
23:18:36 <Lemonizer> thats hard to read
23:18:44 <Lemonizer> a round device with like 8 gold legs
23:19:06 <mamalala> sounds like an opamp
23:19:34 <mamalala> https://www.ebay.com/itm/ML709-OpAmp-Operational-Amplifier-IC-UA709-LM709-NOS-Qty-1-/133011069300
23:19:47 <Lemonizer> yeah sounds like an opamp, that makes sense
23:19:57 <Lemonizer> the rest is passive, resistors and a cap
23:20:09 <mamalala> so that would probably need a +/- supply, using up 3 of the battery connectors
23:20:28 <mamalala> and then you have one cell supplying the test voltage
23:20:51 <Lemonizer> now how to determine the voltage needed ? :> thats the 1 million dollar question
23:21:11 <mamalala> check which of the clip leads go to the ML709, those would be - / GND / +
23:21:44 <Lemonizer> the problem is its not really accessible
23:21:47 <mamalala> i would assume +/- 9 volts for the opamp, and 1.5 volts for the other one
23:22:31 <mamalala> well, they somehow must have assembled it, so there must be a way to disassemble it... after all, it's an old unit, made with metal, and not a modern plastic box with ultrasonic-welded crap
23:23:49 <mamalala> could also be +/- 4.5 volts or so ... dunno about that particular opamp, but most old ones use a somewhat higher voltage compared to modern units
23:25:34 <Lemonizer> theres only one somewhat accessible nut but its stuck :/ and with an extender I dont get the required torque
23:26:24 <hsn93> T3sl4 --> https://snipboard.io/zOVlgn.jpg is this correct ?
23:26:57 <Lemonizer> 9v would be with 6x1.5v batteries I guess
23:27:05 <Lemonizer> idk if it fits
23:27:11 <hsn93> 1khz square (3v3 ac coupled) = (1.485Vrms @ sine 1KHz)
23:28:12 <mamalala> Lemonizer: go for 3+3 1.5v cells first... and try to figure out which one is negative, ground, and positive
23:28:47 <Lemonizer> I can use supplies for that
23:28:59 <Lemonizer> the thing that sucks is that theres no leds
23:29:04 <Lemonizer> that would have helped a bit
23:29:28 <T3sl4> hsn93: and i got with 1x probe (Vrms = 1.48V) <-- i thought you got this, not 1.65
23:29:30 <mamalala> use a low current limit setting, like 10 or 20 mA for the opamp one
23:29:43 <mamalala> the other one should be even lower, i guess
23:30:12 <mamalala> stick a known resistor onto the "inputs" and follow the instructions
23:30:24 <mamalala> then you should see what works and what not
23:30:40 <Lemonizer> im going to try that a bit later I think yes
23:30:46 <Lemonizer> im really curious about this thing
23:30:54 <Lemonizer> it looks nice, and buttons/pots feels great
23:32:03 <Lemonizer> I need to figure out how to properly use the lcr meter too :>
23:32:06 <Lemonizer> its so confusing
23:32:53 <mamalala> well... maybe learn the basics of one thing at a time...
23:33:09 <mamalala> ... the hp scope should keep you occupied for half a year to get the basics :P
23:33:23 <Lemonizer> yeah im making a small list :> first learn how to use whats working, then fix stuff :P
23:33:29 <Lemonizer> yeah haha I figured some stuff already !
23:33:34 <Lemonizer> its really a nice scope :>
23:33:42 <hsn93> T3sl4: 1.65v is Vpk of square wave ...... convert it to foundamental sine wave = 2.1Vpk = 1.485Vrms ..
23:33:58 <Lemonizer> and it doesnt seem to be too much to fix honestly, I'll try to reseat the analog card to see
23:34:38 <T3sl4> where did you measure 1.48 then
23:35:50 <Lemonizer> mamalala on the objectives I have, theres :
23:36:36 <Lemonizer> cal-mem module :P the 18ghz plugin, fix the channel one of the 54201D, get some logic probes and learn how to use it
23:36:47 <Lemonizer> get an electrometer, a null meter maybe
23:36:53 <mamalala> forget about those
23:37:00 <Lemonizer> build a hamon divider/KV
23:37:03 <mamalala> first learn how to use the devices as they are now
23:37:08 <Lemonizer> ho ofc !
23:37:14 <Lemonizer> all that will come after
23:37:20 <Lemonizer> or if I get an insane deal
23:37:38 <mamalala> and probably forget about the cal-mem module as well... as you know they are some sort of unobtainium
23:37:48 <mamalala> yea
23:37:50 <Lemonizer> haha but that would be sooooo cool !
23:37:59 <Lemonizer> just to say, hell I got every options ! :P
23:38:14 <mamalala> the plug-in for the counter should be rather easy to come by... they pop up on ebay from time to time
23:38:20 <mamalala> haha
23:38:24 <Lemonizer> how much do they cost ?
23:38:25 <Lemonizer> usually
23:38:44 <mamalala> let's put it this way: you got all the options for the fluke that are actually documented in the service manual :P
23:38:54 <mamalala> depends
23:38:54 <Lemonizer> thats true yes x)
23:38:56 <hsn93> T3sl4 ,, well https://snipboard.io/mEZfD9.jpg
23:39:13 <mamalala> i have seen some for like 20 euros... untested, as-is.... sometimes for about 100 euros
23:39:23 <Lemonizer> ho thats decent
23:39:55 <mamalala> but then, be aware of what you actually need... the counter is already very good as is, several 100 mhz... unless you have a real need for more, you probably wonÄt need the plugin
23:39:57 <T3sl4> hsn93, Vrms of a square wave equals Vpk
23:40:05 <T3sl4> Vmax seems to be reading spikes or noise
23:40:23 <T3sl4> can zoom in on the waveform and see where it's looking
23:40:25 <hsn93> oooooooooh
23:40:33 <mamalala> i mean, how many circuits do you build where you need to check that a clock is accurate and stable, and that is also in the >200 or so MHz range
23:40:44 <T3sl4> so you measured a 1.48V square wave, which works out correctly, so it seems the FFT is reading about right
23:41:28 <Lemonizer> honestly mamalala, its not that I need it, its that I want it :P
23:41:35 <Lemonizer> I like to hunt for stuff !
23:41:38 <Lemonizer> but I dont want to pay a lot
23:41:50 <Lemonizer> so im just waiting for neat deals like I did for the rest of my stuff
23:42:21 <mamalala> hehe, i can relate to that :)
23:42:30 <hsn93> T3sl4 but i dont know how it gets 1.48 there is no spike https://snipboard.io/K4YCx7.jpg
23:42:43 <hsn93> thats why i considered it 1.65
23:43:23 <T3sl4> shrug
23:44:05 <Ampera> I like Vmax without the m
23:44:29 <hsn93> the m ?
23:44:29 * Ampera co1ls T3sl4 up into a ball and rolls him down the street
23:44:34 <Ampera> hsn93, Vax
23:44:38 <Ampera> or rather VAX
23:44:47 * T3sl4 whees like a lil piggy
23:44:55 Join: JoePublic ([email protected]) to #EEVblog
23:45:11 <Lemonizer> I also need something to measure temperature up to at least 0.1C accuracy]
23:45:17 <hsn93> i see
23:46:08 <mamalala> hsn93: you really should read the scopes manual, and also read up on some of the basics of digital signal processing
23:46:34 <mamalala> all the stuff you ask or wonder about is pretty well documented in many, many places
23:47:08 <Lemonizer> but sometimes it feels better to have a person to chat with :>
23:47:32 <Ampera> Lemonizer, I'm basically here all day now at this point
23:47:34 <mamalala> Lemonizer: well, now that you have the fluke, you can use a simple PTC or NTC or platinum sensor, and derive the actual temp from the resistance :)
23:47:39 <Ampera> not that I wasn't before
23:47:53 <Lemonizer> hmmm lemme look :P thanks
23:48:08 <mamalala> i think a platinum sensor is more linear, iirc
23:48:16 <mamalala> and they are somewhat cheap as well
23:48:24 <hsn93> mamalala the manual is actually opened after u suggested to me im comparing and verifying from results i've go + math
23:48:47 <mamalala> since you can do 4-wire with the instrument, you can use PT100 or PT1000 sensors with no issue, i guess
23:49:01 <Lemonizer> what accuracy can I expect with those ?
23:49:08 <Lemonizer> im looking at a PT1000 right now
23:49:49 <mamalala> Lemonizer: assuming that the fluke is still somewhat in calibration on ohms (which is not a given, since the working ohms module is a replacement), the deciding factor is the sensor
23:50:31 <Lemonizer> I need to get a cheap resistor standard to check that and other dmms, lcr meter too
23:50:34 <Lemonizer> but later
23:51:11 <hsn93> mamalala i like keysight labs youtube channel lots of great stuff
23:51:13 <mamalala> well, just get a 100, 1k and 10k resistor at 0.01% ... that will give you at least a good idea of what is going on
23:51:24 <Lemonizer> yeah
23:51:27 <mamalala> also, make sure to use a 4-wire setup then, if you want accuracy
23:51:34 <Lemonizer> yeah thats true
23:51:41 <Lemonizer> I can use those kelvin clips from the lcr meter
23:51:44 <Lemonizer> ha wait no I cant
23:51:52 <Lemonizer> bnc terminaisons
23:52:15 <mamalala> hsn93: looking at pretty videos is one thing ... reading a manual front-to-back is another ... and actually understanding what is written there is yet another thing
23:52:33 <hsn93> lol
23:52:40 <mamalala> Lemonizer: you can get bnc to banana converters cheaply
23:53:01 <mamalala> but then again, it all depends on what level of accuracy you want :)
23:53:05 <Lemonizer> yeah but idk if its worth it, I planned to get or make new kelvin clips anyway
23:53:13 <Lemonizer> id be happy with a true 0.1C :>

23:53:52 <Lemonizer> those would be nice honestly
23:54:01 <Lemonizer> the fluke will be more than enough right ?
23:54:28 <Lemonizer> im not getting one today but just taking informations
23:54:45 <Lemonizer> I'll need an adapter

23:56:10 <Guest|52> whats are the experiences with a extech multimeter?
23:58:28 <Ampera> So we're agreed then, that's how we restore communism to the world order.
