00:18:28 <rust_collector> hourning
00:18:35 <rust_collector> ???
00:18:38 <rust_collector> morning?
00:21:13 <K> eating.
00:21:28 <hsn> ok so the fire siren is ringing
00:21:29 <rust_collector> me too
00:21:39 <K> you are ringing?
00:21:41 <hsn> and 3 of us in the room not giving shit
00:21:43 <rust_collector> yes
00:21:47 <hsn> xD
00:21:59 <K> hsn, prolly should check
00:22:20 <hsn> ah its bullshit siren
00:25:57 <K> it triggers on too much bulshit?
00:26:22 <hsn> i guess
00:26:37 <hsn> now it off
00:26:54 <hsn> maybe the fire has eaten the cables hahhaha
00:27:27 <hsn> and morning rusty
00:36:02 <Lemon> aye
00:36:16 <Lemon> the parcel-receiving streak has begun
00:36:25 <hsn> :<
00:36:37 <Lemon> got the gold plated banana plugs, the adc module and some nice push buttons
00:36:47 <hsn> real gold ?
00:37:10 <rust_collector> yes, melted teeth from the great war
00:37:19 <Lemon> looks like it yes but probably reaallllyy thin
00:37:30 <Lemon> I was quite surprised honestly, they feel nice for the low price I paid
00:37:42 * Ampera squeezes Lemon
00:37:43 <Ampera> how do m9
00:37:57 <Lemon> well doin gr7 and you ?
00:38:11 <Ampera> awegoiawpejgiopawejgpoiawegawpoiejgawoipejgopaiwejgawoipegjawoiepgjawpoghdiugawevnwaeiuhfgwaeoiuhawieoghwaoiueghawioeghaweiughaweoighuaweioghnaew, and you?
00:38:30 <Lemon> hmmm its more about keoopekoekopppoekope I think
00:38:35 <Ampera> cor
00:38:47 <K> lemons speaks finnish
00:38:48 <Ampera> I'm hungry and it's not even 12
00:39:20 <hsn> guys i dont know how +/- 1 .. stop cryptography me :)
00:39:22 <Lemon> heh doesnt matter go grab a snack
00:39:23 <Ampera> K, isn't it the snow that speaks finnish?
00:39:28 <Lemon> https://www.ebay.com/c/27002598044 what a beautiful device
00:39:51 <hsn> lemon ebay should give u coupon by now
00:39:56 <hsn> loyality points
00:40:17 <K> and a card on xmas
00:40:21 <Lemon> ho you know I looked at a few things that I didnt even want to buy, one of them were a random genrad digibridge at 950 usd, and I received an offer for 800 lol
00:40:24 <Lemon> thats weird
00:40:32 <Lemon> it seems you can send offers to people who watched your add
00:40:35 <Lemon> ad
00:41:08 <K> he took a peek at your purchase history and saw an oportunity
00:42:15 Join: Lemon_ ([email protected]) to #EEVblog
00:42:37 <Lemon_> since when I lose my connection when the phone rings, lol
00:42:42 <Lemon_> have I gone back in time ?
00:43:02 <K> nope
00:43:10 <rust_collector> you lost that time
00:43:26 <K> old man thyme, he gets everyone, eventually.

00:44:42 <Lemon> I wanted to make myself a little stock of parts, and I miss caps mostly
00:44:44 <Lemon> https://www.ebay.fr/itm/Bag-of-Mixed-Polyester-Capacitors-over-800-pieces-68-values-list-below-Z3263/254276562898?hash=item3b34106fd2:g:UkAAAOSwJPVdEOVx
00:44:53 <Lemon> watcha think of that one ? looks cheap, good values, new stuff
00:44:59 <Lemon> those dont really age like lytics
00:46:42 <Lemon> but I think the next somewhat big purchase I'll make will be related to resistance calibration of my two nice dmms
00:46:59 <Lemon> I kinda want to buy some from Edwin Pettis
00:47:05 <Lemon> I'm waiting on an invoice
00:47:27 <Lemon> the good thing is that he can calibrate them, and I trust him for the quality
00:47:34 <Lemon> man got over 40 years of experience
00:47:46 <Lemon> he got an sr104, a 242 bridge if im right
00:51:55 <Lemon> but yeah with his resistors I'll be able to gain a nice accuracy, then I need to find someone that can calibrate within at least 4ppm or so my lm399 roadrunner's board, and the various SSG caps I have
00:52:23 <rust_collector> In this case, I have to quote a bright young person
00:52:38 <rust_collector> awegoiawpejgiopawejgpoiawegawpoiejgawoipejgopaiwejgawoipegjawoiepgjawpoghdiugawevnwaeiuhfgwaeoiuhawieoghwaoiueghawioeghaweiughaweoighuaweioghnaew
00:52:49 <Lemon> hmmm theres some truth in that yes
00:52:57 <Lemon> 'ghuaweioghn'
00:53:04 <Lemon> I dont totally agree tho
00:53:35 <Lemon> https://www.ebay.fr/itm/Resistance-standard-resistor-P310-P321-P331-Coil-analog-of-LEEDS-ESI-iet-GR/233383774180?hash=item3656c1c7e4:g:ObcAAOSwHPNbFnaO
00:53:43 <Lemon> I want to get one of those once my meter is calibrated
00:53:57 <Lemon> I think they are made to be immerged in oil
00:54:58 <rust_collector> anyway, did you watch marco reps temp controlling thing video, the other day?
00:55:12 <Lemon> ha maybe not ?
00:55:24 <Lemon> if it came out like 2 days ago or what, I didnt
00:55:35 <rust_collector> something around there

00:58:01 <rust_collector> well, you keep nagging about caps. I am still figuring out this riekstini thing
00:58:09 <rust_collector> very busy
00:59:45 <Lemon> figure it !

00:59:56 <Lemon> I got so me love for those old USSR resistors
01:00:25 <rust_collector> sold in a lot of 1
01:00:27 <rust_collector> ok
01:00:36 <Lemon> yeah
01:01:06 <Lemon> I bought a pack of 18, 0.1% 10 watts or so that looked like them
01:01:06 Quit: hsn93 ([email protected]) Ping timeout: 121 seconds
01:01:12 <Lemon> for 10 euros, including 7 of shipping lol
01:01:41 <K> what is giving you problems, rust_collector ?
01:02:41 <rust_collector> naaah, i just feel like I have seen one of those irons, but I guess maybe it was something else
01:02:56 <rust_collector> so, I need small metal cup things, I guess
01:04:32 <Ampera> oh nice my air is out for delivery
01:04:34 <Lemon> shipping is really a pain, many things from ukraine/russia etc are so interesting, but it kinda kills the deal
01:08:34 <K> rust, yea
01:08:46 <Lemon> gold plated tellurium copper binding posts
01:08:50 <Lemon> I dont want to know the price
01:09:05 <Lemon> audiophiles be like
01:09:11 <Lemon> 'I'll take 20'
01:09:20 <rust_collector> someone dumped a big rhode and schwartz box outside work yesterday. I wonder if anyone knew what that thing cost
01:09:39 <Lemon> 'it turned my 10 euros amp into an high end device !'
01:09:47 <Lemon> what >??>
01:09:49 <Lemon> what was it ?
01:10:00 <Lemon> grab it !
01:10:16 <K> what kind of box?
01:10:19 <rust_collector> well, they are not that expensive....
01:10:29 <rust_collector> cardboard box
01:10:31 <K> haha
01:10:35 <Lemon> ha
01:10:52 <rust_collector> https://uk.rs-online.com/web/p/binding-posts/8884657/
01:11:09 <rust_collector> that is not waaay super expensive crazy
01:11:44 <Lemon> but I think its not solid tellurium copper
01:11:53 <K> rust_collector: https://www.ebay.com/itm/Sets-50-pcs-Metal-Mold-Forms-For-Sweet-Russian-Oreshki-Pastry-Cookie-Nutlets/163646419709
01:11:54 <rust_collector> I did look at the label on the box, it was for a telecoms company, and i t was a blahblahblah amplifier
01:12:16 <Lemon> I looked around and usually its more like 30 bucks + each
01:12:27 <K> though those appear to be made from stamped steel, not cast alu
01:13:02 <rust_collector> well, that is good. I do not like aluminium in my food
01:13:24 <rust_collector> and... they are from ukraine, lol
01:13:29 <K> yeah
01:13:54 <K> 12 eur might be under any additional tax/customs nonsense
01:14:23 <Lemon> I envy xDevs lab honestly
01:14:36 <rust_collector> Constructed from a copper or gold plated tellurium copper body with a polycarbonate insulator
01:14:39 <Lemon> I'd give so much to work with someone in a lab like this, testing devices, fixing them, learning tons of stuff
01:14:41 <rust_collector> I dunno
01:14:42 <K> there is also this - https://www.ebay.com/itm/Form-for-baking-Nuts-Cookies-Cookie-Candies-Metal-Big-Mantel-Large-Pan-Nut-Big/282969564023
01:15:06 <K> haven't used one like that myself thought
01:15:11 <rust_collector> yes, that is the thing I was thinking of
01:16:03 <rust_collector> I just think I have seen one, but... maybe I am mixing it up with one of the other iron things
01:16:40 <K> yes, there are similar implements for other types
01:19:01 <Lemon> I want to be part of something, having calibrated devices so I could calibrate things for others, or whatever
01:19:25 <Lemon> I'll probably have to ask some people to calibrate stuff for me so I want to return the favor to others
01:20:56 <rust_collector> I think it is time to find my shorts, and get outside, and do things
01:21:26 Join: Lemon_ ([email protected]) to #EEVblog
01:21:36 <Lemon_> those sr104 are really impressive, some drifting only 0.02ppm per year
01:22:02 <Lemon_> but they are goddamn big for a simple resistor lol
01:22:04 <rust_collector> most of todays job is just a lot of sanding. but everything is full of pollen, so no one will notice
01:22:26 <rust_collector> well, MAYBE, they are not simple resistors
01:22:52 <Lemon_> theres an ultra stable resistive element in a bigass oil tank
01:22:57 <Lemon_> with a rtd measuring temp
01:23:04 <Lemon_> and some trim resistors added over the years
01:23:24 <rust_collector> i want a bigass oil tank, with r2d2 measuring temp
01:23:29 Quit: Lemon ([email protected]) Ping timeout: 121 seconds

01:23:29 Nick: Lemon_ is now known as Lemon
01:30:32 <Lemon> I really wonder how good my fluke resistors are, its hard to tell with the hp as it shows only 5.5 digits, and the fluke seems noisy
01:30:39 <Lemon> I need a shielded box or whatever

02:16:53 <Lemon> hi boi
02:20:26 <Lemon> Ysjoelfir I really cant remove those security 4mm posts on the little boxes you gave me
02:20:31 <Lemon> I can twist them, but nope
02:21:01 <Lemon> they look to be really nice quality
02:23:11 <Lemon> if you have any pro trick im taking them !
02:27:03 <Lemon> ok I managed to remove one
02:29:30 <K> use harsh language!
02:35:45 <Lemon> yeah I got 4 out of 6, of the first box
02:35:49 <Lemon> two seems harder
02:38:49 Join: hsn ([email protected]) to #EEVblog
02:57:23 <Ysjoelfir> well, they are fastened with handtools, so...
02:58:58 <Ysjoelfir> basically... they have two flat flanges on the inner side. grab that with either a pair of pliers or with a fitting wrench. after that you just have to loosen the locking ring with another set of pliers.
02:59:43 <Ysjoelfir> the original tool for that is basically a tube with two... "points" that slide over the posts from the inside and a 4mm security plug to hold it on the other side. nothing special
03:13:27 <rust_collector> what kind of noise does a fluke make anyway?
03:13:41 <Ysjoelfir> beep
03:13:50 <rust_collector> aah, that is annoying
03:17:14 <K> go home time, yay.
03:17:17 <K> cya
03:18:23 <Ysjoelfir> cu K
03:26:09 <Lemon> Ysjoelfir I managed to do it by blocking the ring with a screwdriver and twisting in the other side the plastic part with a plier, nothing is damaged so perfect :> do you know their composition ? pure copper gold plated or maybe tellurium whatever ?
03:26:14 <Lemon> they seem to be really nice quality
03:26:35 <Ysjoelfir> I can tell you exactly what connectors those are
03:27:44 <Lemon> neat ! :>
03:27:58 <Ysjoelfir> as soon as I remember the brand that is
03:34:11 <Ysjoelfir> It should be Multi Contact (now Stäubli) SLB4-G types IIRC
03:34:42 <Ysjoelfir> we also used another brand when MC got bought from stäubli and there were "unavailabilities", but I can't remember which brand that was
03:34:52 <Ysjoelfir> but they are basically identical from their specs
03:36:38 <Lemon> lemme check thanks !
03:38:17 <Lemon> hmmm thats 'nickel goldened? idk the word
03:38:26 <Lemon> so maybe not gold plated
03:38:53 <Ysjoelfir> its brass, polated with nickel plated with gold
03:39:12 <Lemon> do you think its alrighty ? or copper would be better ?
03:39:15 <Lemon> plated copper
03:39:23 <Ysjoelfir> its perfectly fine
03:39:51 <Lemon> they look great :>
03:39:59 <Lemon> thanks again dude those things greatly help me !

04:48:00 <Lemon> alright I removed every plugs
04:48:09 <Lemon> that took time but im quite happy, theres 12 pairs :>
04:48:24 * Ysjoelfir has the appropriate tool
04:48:27 <Ysjoelfir> 0:-)
04:50:26 <Lemon> heh a flat screwdriver, a needlenose plier and bam !
04:51:00 <Ysjoelfir> Or just the appropriate tool^^ takes way less time :)
04:52:50 <Lemon> yeah but I cant justify getting a tool for a single usage x)
04:54:13 <Ysjoelfir> no? :O
04:54:39 <Lemon> and thats without saying thats those goddamn tools are usually hard to come by and fucking expensive xD
04:56:31 <Ysjoelfir> naah, come on, its just around 120€
04:56:50 <Ysjoelfir> I gont mine for free
04:56:55 <Lemon> ho I'll take 16 then, in case I break/lose fifteen of them !
04:56:55 <Ysjoelfir> from the trash of work, as usual
04:57:03 <Lemon> you're so lucky xd
04:57:19 <Ysjoelfir> well... you can immagine how they should look. basically a tube with two nipples
04:57:33 <Lemon> yeah, cost maybe 50 cents to make
04:57:40 <Ysjoelfir> one of the nipples was broken off. guess what I did to it.
04:58:00 <Lemon> cut the other, filled the middle of the tube to have two new ones
04:58:08 <Ysjoelfir> exactly.
04:58:16 <Lemon> clever boi
04:58:25 <Ysjoelfir> took like.... 5 minutes of filing
04:58:30 <Lemon> I did something similar for security whatevertheirname screws on some power bricks
04:58:43 <Lemon> but now I got Ifixit :copyright: tools !
05:00:23 <Ysjoelfir> woah
05:00:29 <Ysjoelfir> they must have been friggin expensive!
05:00:35 <Lemon> 30 euros the kit man !
05:00:41 <Lemon> and theres 64 bits
05:00:46 <Lemon> 48 for the bigger ones
05:00:53 <Lemon> for real they are lifesavers
05:01:04 <Lemon> theres everything in it, even tiny ass stuff for cellphones or whatever
05:01:11 <Lemon> some bits I never saw before aswell
05:10:02 <Lemon> hey Ysjoelfir whatcha think of this https://www.ebay.fr/itm/Bag-of-Mixed-Polyester-Capacitors-over-800-pieces-68-values-list-below-Z3263/254276562898?hash=item3b34106fd2:g:UkAAAOSwJPVdEOVx to build myself a little part bin ? I miss those type of caps
05:12:42 <Ysjoelfir> sure, why not? I doubt those will be bad
05:13:04 <Lemon> yeah I mean, for the price etc it looks good ? 68 values is nice
05:13:14 <Lemon> good chance I'll find the right one if I make something that needs it
05:13:49 <T3sl4> Lemon: looks like a pretty good selection, i recognize brand names in there
05:14:02 <Ysjoelfir> jep, I think its pretty ok
05:14:15 <Lemon> ha good ! glad to hear that :>
05:14:21 <Lemon> he sells many things, like this too https://www.ebay.fr/itm/Bag-of-mixed-metal-can-transistors-many-different-types-new-old-stock-Z3618/254383087790?hash=item3b3a69e0ae:g:wiAAAOSwvIldnJLh
05:14:34 <Lemon> idk how are those, I have some chinese no names ones, but not in metal cans
05:14:43 <DHess_US> The box capacitors aren't as useful as smaller leaded ones.
05:14:44 <Ysjoelfir> uh, I like metal can trannies.
05:14:56 <Ysjoelfir> but beware of whiskers
05:15:03 <DHess_US> Otherwise, yes, polyester capacitors are fine for general purpose use including decoupling.
05:15:27 <DHess_US> But I usually buy separate 0.1 and 0.01uF X7R ceramic capacitors.
05:15:27 <Lemon> https://www.ebay.fr/itm/1KG-bag-of-mixed-TRANSISTORS-and-DIODES-BIG-SELECTION-old-stock-Z3609/293250756270?_trkparms=aid%3D1110001%26algo%3DSPLICE.SIM%26ao%3D1%26asc%3D20131003132420%26meid%3Deb891c73cdcc47358200b4d7a77a68a7%26pid%3D100005%26rk%3D2%26rkt%3D4%26mehot%3Dpf%26sd%3D254383087790%26itm%3D293250756270%26pmt%3D0%26noa%3D1%26pg%3D2047675&_trksid=p2047675.c100005.m1851 also this
05:15:39 <Lemon> ha yeah I also want other types aswell
05:15:52 <Lemon> kits like this save me a great amount of cash usually
05:16:03 <Lemon> betting on the fact that one day I'll need one of them
05:17:17 <Lemon> I bet those metal can trannies are of better quality than the chinese black plastic ones I have
05:17:22 <Lemon> probably better specs too
05:18:24 <Lemon> now thats a big mofo ! https://www.ebay.fr/itm/LED-7-Segment-displays-181mm-LSA70-21474EC-Super-RED-625mm-ZB165A/292613879246?hash=item44212575ce:g:ahkAAOSw1NJbLQaV
05:21:14 <Lemon> I want to replace my chinese noname parts with good quality ones
05:21:46 <Lemon> its great for lil circuits like led blinkers or small stuff but if I want to build a serious bin part, I better start getting good parts now
05:21:46 <hsn> ok hear this since lemon is here
05:22:01 <hsn> and talking about polyster caps
05:22:18 <hsn> The local pub was so sure that it’s bartender was the strongest man around that they offered a standing $1000 bet.
05:22:18 <hsn> The bartender would squeeze a lemon until all the juice ran out into a glass, then hand the lemon to a patron. Anyone who could squeeze out one more drop of juice would win the money.
05:22:18 <hsn> Many people had tried over time, but nobody could get out another drop.
05:22:18 <hsn> One day a scrawny little man came in, wearing thick glasses and a polyester suit, and said in a tiny, squeaky voice, “I’d like to try the bet. “
05:22:20 <hsn> After the laughter has died down, the bartender agreed, grabbed a lemon, and squeezed. He then handed the wrinkled remains of the lemon to the little man.
05:22:23 <hsn> The crowds laughter turned to complete silence as the man clenched his fist around the lemon and six drops fell into the glass.
05:22:26 <hsn> As the crowd cheered, the bartender paid the little man the $1000 and asked, “what do you do for a living? Lumberjack? Weightlifter? What?”
05:22:31 <hsn> The man replied, “Nope. I’m a tax collector. “
05:23:11 <hsn> although i dont find it funny or i dont understand it .. but it contains both lemon and polyster
05:23:14 <Lemon> pfffrtt
05:23:31 <Lemon> because tax collectors squeeze every bit of money out of you
05:23:48 <hsn> yeah thats not funny its bad :)
05:24:04 <hsn> and sad
05:24:19 <Lemon> and pretty well known :P
05:24:33 <Lemon> I heard many variations of this one
05:32:41 <Lemon> Ysjoelfir do you think its a good idea to get that pack of metal can transistors ? to use instead of the classic chinese noname pack of those tiny black plastic ones ?
05:43:39 <Ysjoelfir> well, if you keep in mind that there may be whiskers in them.. sure? I like those packages
05:43:49 <Lemon> by whiskers you mean bad ones ?
05:43:57 <Ysjoelfir> no

05:44:26 <Ysjoelfir> there. extra in that strange language for you :P
05:45:12 <hsn> whiskers = short circuit hairs coming from chip manufacturing ?
05:45:26 <Lemon> hmmmmm and does it impact them greatly ?

05:52:19 <Lemon> heavy breathing
05:52:29 <Lemon> theres a cal sticker dating from 2019 on it
05:52:39 <Lemon> and it comes with the weirdass cable
05:53:31 <Ysjoelfir> that popped up in my search reminder today, too.
05:53:43 <Lemon> its a really interesting price
05:53:46 <Lemon> but still high
05:53:47 <Ysjoelfir> regarding the whiskers: jep, it impacts them greatly. its like a short
05:55:25 <Lemon> lets forget about them
05:55:36 <Lemon> who lends me at least 250 euros ?
05:55:50 <rust_collector> maybe you, if you are lucky
05:56:01 <Lemon> well I can lend myself the other 250
05:56:10 <rust_collector> that is 250
05:56:21 <Lemon> rusty I want that solartron
05:56:25 <Lemon> I want it
05:58:51 <rust_collector> I like the name
05:59:56 <rust_collector> oh, a xx71, they say it is quite an upgrade from the 70, or maybe it was 61 and 60...
06:00:08 <Lemon> 7.5 digits, we are hitting the high level rusty
06:00:13 <Lemon> and its calibrated
06:00:35 <rust_collector> yes, pretty useless. sure it is a good device probably
06:02:07 <Lemon> well in fact its not much more accurate than my meters
06:02:36 <rust_collector> I am not saying there is anything wrong with it
06:03:03 <rust_collector> so, what meter would you sell to get that one?
06:03:18 <Lemon> I just thought about it but no, I cant
06:03:28 <Lemon> and it wont add much more to what I can do already
06:03:36 <Lemon> its a tad better but nothing to justificate it
06:03:51 <Lemon> I already reached a nice level with the two 6.5 digits I haver
06:03:56 <rust_collector> it is not that expensive...
06:04:34 <Lemon> their 24h specs, which can be even better once they aged, if I can adjust them with standards can hit like 4-7ppm on DCV
06:04:57 <Lemon> a 3458a will lower that to 1-2ppm if im right
06:05:05 <Lemon> maybe less on short term, idk
06:05:25 <Lemon> thats not a big enough difference for me to spend several thousands, i'd rather spend it on something else
06:05:33 <Lemon> like a nice electrometer, standards, new projects etc
06:11:56 <rust_collector> pizza....
06:12:05 <rust_collector> you can buy a lot of pizza for that

06:18:44 <Lemon> so I roughly measured that chinese 1% resistor that was really tight on tolerance
06:19:32 <Lemon> from 21.93C to 24.42C, it went from 74.9988k to 75.0095k
06:20:32 <rust_collector> oh no!
06:20:34 <Lemon> thats roughly +32.2ppm/C
06:20:52 <Lemon> but well the sensor is in a cardboard box with the resistor, thats far from being perfect
06:20:59 <Lemon> it just gives us a rough idea
06:21:04 <Lemon> its not that bad honestly
06:21:11 <Lemon> I thought they'd were way worse
06:21:13 <rust_collector> hmm, is there any resistors that get a negative number?
06:21:19 <Lemon> seems they are 50ppm/C resistirs
06:21:23 <Lemon> yes it can
06:21:32 <Lemon> thats why we put two in series to cancel each other when possible
06:21:40 <Lemon> I planned to try that, if I find two nice specimen
06:21:53 <Lemon> but I first need to build a better fixture, and manage to pull data via gpib
06:22:03 <rust_collector> ok, except that maybe both go the same way, so...????
06:22:04 <Lemon> right now I simply wrote down the values from time to time
06:22:05 <DHess_US> There are all kinds of special purpose resistors.
06:22:24 <Lemon> no if you characterize one and see that it got a negative tempco
06:22:28 <Lemon> it will always go negative
06:22:32 <Lemon> same for the other way around
06:22:40 <DHess_US> Like -120ppm/C for compensating polystyrene capacitors
06:22:43 <Lemon> so if you get a minus 15 and plus 15, bam
06:22:59 <Lemon> how do you compensate caps with resistors ?
06:23:16 <DHess_US> In charge balancing ciruits.
06:23:30 <Lemon> another complicated thing ? :>
06:23:36 <DHess_US> Not really
06:24:24 <Lemon> also I decided to get some calibrated resistors from Edwin, so I can calibrate my 3456a and 8502a
06:24:31 <Lemon> that'll be a nice thing to have
06:24:35 <Lemon> and not terribly expensive
06:25:25 <DHess_US> Oh, actually +120ppm/c
06:27:18 <DHess_US> Figure 12a on page 11 here, https://www.analog.com/media/en/technical-documentation/application-notes/an03f.pdf
06:29:30 <Lemon> ha ok I see I thought about a different thing
06:30:00 <Lemon> Im thinking about something
06:30:08 <Lemon> with the right number of connections, with 10 x 1k resistors
06:30:28 <Lemon> you can get any value from 100R to 10k right ? well, in decades, so 100, 200, 300, 1k, 2k, 3k etc
06:30:37 <Lemon> not 3,100k for example
06:30:54 <Lemon> by putting them in paralel or series
06:49:30 <DHess_US> https://vid.pr0gramm.com/2020/06/03/784146d1b01f4f2b.mp4
06:59:04 <Lemon> ho I just realize something
06:59:14 <Lemon> in the Fluke 742A
06:59:25 <Lemon> those hermetic WW resistors
06:59:42 <Lemon> I have some of them that came from a broken ohm module, that mamalala gave me along the 8502a
07:00:26 <Lemon> I have two smaller ones and a bigger one, they are 0.08% parts, 201k, 272.whatever k and 4.091M
07:00:32 <Lemon> I bet those got a really nice tempco
07:02:02 <rust_collector> I do think you are more likely to get your ass kicked, if you bring the wife
07:22:43 <Ampera> eeeeeeeeeeeeeeeeeeeeeeeeeeeeee
07:53:52 <rust_collector> æææææææ?

18:11:54 <Lemon> whats poppin gajs
18:27:45 <Ysjoelfir> My resistors are popping
18:27:51 <Ysjoelfir> whats a gaj?
18:28:19 <Lemon> a guy :>
18:29:11 <Ysjoelfir> oh
18:29:11 <Ysjoelfir> ok
18:30:08 <Ysjoelfir> I just measured some nice foil resistors. TK of 50. 220mR nominal resistance. drifted by 800µR with a delta_theta of 155K. what do you think, lemon?
18:31:06 <Ysjoelfir> nice little calculation task for you <3
18:31:18 <Lemon> I think I didnt get the delta_theta part :> I wanted to get more info on that 'alpha and beta tempco'
18:31:28 <Lemon> TK of 50 so 50ppm/K I guess
18:31:32 <Ysjoelfir> delta theta is just the difference in temperature
18:31:39 <Lemon> it moved by 0.8 mR
18:31:55 <Lemon> haa so 800uR/155
18:31:57 <Lemon> basically
18:32:40 <Ysjoelfir> yes, it drifted by 800µR while heating up from 25 to 180°C.
18:33:54 <Lemon> thats approx 1ppm/C ?
18:34:09 <Lemon> 5uR per K
18:34:48 <Lemon> hmmm waity
18:35:40 <Lemon> 220nR is 1ppm
18:35:44 <Lemon> if im right
18:36:11 <Lemon> so thats more like 25ppm
18:36:13 <Lemon> per K
18:36:16 <Lemon> no ?
18:36:25 <Ysjoelfir> I actually didn't calculate it yet
18:36:42 <Ysjoelfir> but that sounds like what I would expect
18:36:55 <Lemon> but logically you take the nominal so 2200000nR/ 1000000
18:37:01 <Lemon> thats 220nR
18:37:08 <Lemon> for 1ppm
18:37:18 <Lemon> it drift 5uK per K
18:37:31 <Lemon> 5000nR/220
18:37:33 <Ysjoelfir> exactly. then divide the drift by the 1ppm value to get ppm/k :)
18:37:44 <Lemon> thats 22.72nR
18:38:09 <Lemon> so wait
18:38:36 <Lemon> no im wrong
18:38:50 <Lemon> I divided the per K drift by 1ppm of the nominal value
18:39:31 <Lemon> thats 22.72 ppm/K
18:39:34 <Lemon> not nR
18:39:36 <Lemon> right ?
18:39:53 <Ysjoelfir> yes.
18:40:08 <Lemon> alright ! im getting 12 y/o level at maths, yeahhhhh
18:40:19 <Lemon> better than my state at first :P
18:40:38 <Ysjoelfir> XD
18:43:31 <Ysjoelfir> so, lemon, would you use that resistor?
18:44:51 <Lemon> well it depends, if its perfectly linear why not as I can compensate it, and maybe in a closer span like from 20 to 40C it got tighter specs, thats worth looking too :> but I think 22.7ppm/K is a bit high for what I want to do
18:47:31 <K> hello
18:47:36 <Lemon> what do you think ?
18:47:38 <Lemon> hey K !
18:48:47 <Ysjoelfir> For your applications... potentially yes. For my applications... its perfect. We shoot for 2% total accuracy over the whole current range... xD
18:48:51 <Ysjoelfir> Hi K
18:49:06 <Lemon> but which application you are doing ? :>
18:50:37 <Ysjoelfir> its still for my project at work, the reference impedance
18:51:07 <Ysjoelfir> maybe you remember, a few monts back, I measured power resistors for their behaviour
18:51:25 <Halcyon> Evening gents
18:51:26 <Ysjoelfir> make that characteristics. I don't think resistors behave at all :P
18:51:28 <Ysjoelfir> Hi Halcyon
18:51:34 <Halcyon> How's it going?
18:51:42 <steve30> hi
18:51:57 <Ysjoelfir> Hot, my resistors are at 180C right now :) How about you, Halcyon?
18:51:58 <Halcyon> Hey Steve :)
18:51:58 <Lemon> ho right ! which model of resistors were you using ? for which power ? :>
18:52:15 <Lemon> but theres also hysteresis to take in account no ?
18:52:31 <Lemon> also power cycling, etc
18:53:27 <Halcyon> Is that good or bad Ysjoelfir ?
18:53:50 <Lemon> also you just measure two points ?
18:53:56 <Lemon> assuming they are perfectly linear ?
18:54:32 <Ysjoelfir> back then? Arcol HS100 series. Right now I am evaluating Riedon PF2472 -> https://riedon.com/media/pdf/PF2470.pdf
18:54:44 <Ysjoelfir> heh, hell no. I'm taking a sample every 30ms, Lemon
18:54:59 <Ysjoelfir> Halcyon - its to be expected when I cook them with 20A^^
18:55:14 <Ysjoelfir> so... its.... indifferent
18:55:30 <Lemon> and what are you using to measure their value + temp ? thats interesting :> the power analyzer can do all that ?
18:56:23 <Ysjoelfir> yes. it can measure power, so it can also measure impedances^^
18:56:51 <Ysjoelfir> and the temperature.. well, I have a PSI (process signal interface) addon card in mine, which allows me to measure several values if I want
18:57:00 <Lemon> damn, the older one you got is accurate enough to do that too ?
18:57:13 <Lemon> thats really cool !
18:57:40 <Lemon> I've been simply using my 3456a and my homemade thermometer with a sensor in a cardboard box, with the resistor, and writing down myself the values xD
18:57:48 <Lemon> as I still need to figure out gpib
18:58:02 <K> Ysjoelfir, impedances for what frequencies?
18:58:06 <K> line?
18:58:16 <Ysjoelfir> sure, but it's a bit harder to readout as it only has GPIB and no nice software GUI with logging features and export to excel.
18:58:28 <Lemon> thats the fun part !
18:58:38 <Lemon> can you show it to me when you have time ? :>
18:58:43 <Lemon> the older one
18:58:52 <Lemon> I think I saw it but briefly
18:59:06 <Ysjoelfir> K - DC to 10MHz with the measuring channels I have in mine. we also sell ones with lesser specs
18:59:38 <K> Ysjoelfir, ok
19:00:17 <K> 10MHz @20A could be quite funky
19:00:20 * steve30 hugs Halcyon
19:01:21 <Ysjoelfir> well, we also sell current sensors of various kinds that can measure up to several kiloampere at that frequency. No idea for what you would use that though
19:02:22 <Ysjoelfir> Lemon - sure, as soon as I'm home
19:03:07 <Lemon> this thing really interest me :> I have no idea if the price you want to sell it for will be reachable for me, but damn I could find good use for it :P
19:03:54 * Halcyon tickles Steve
19:04:07 <Ysjoelfir> I'm not sure about a price yet. those are hard to find used, so I could make a good penny with it, but I like that you are interested in metrology and want to support that. so... yeah. no idea yet^^
19:04:16 * Ysjoelfir hands Halcyon a feather
19:04:54 <Halcyon> Heh
19:05:43 <Lemon> thats really nice of you <3 but I dont want to make you lose money especially if you need it !
19:06:16 <Ysjoelfir> I won't gift it though xD
19:06:42 <Lemon> ofc xd
19:06:59 <hsn993> heh guys .. can casted aluminum be milled ?
19:07:02 <Lemon> I never said that, you already did a lot :P
19:07:13 <K> hsn993, yes
19:07:46 <hsn993> K, our metal shop says it will break because its casted ?
19:07:48 <K> well, in my experience at least, but it also might depend on shape
19:08:27 <hsn993> its flat side cap for aluminum extrusion enclusure
19:08:28 <K> if it is thin or flimsy, then it might be problematic to clamp it down
19:09:36 * Halcyon nibbles on Ampera's earlobe
19:09:37 <K> if you have one to spare ask to do it anyway
19:11:37 <hsn993> yeah i've extras i will do it .. but then if there is 10% chance it breaks .. what to do for the final product .. buy 1100 pieces for each 1000 product ? or actually if they find a way to mill it .. the result will be 99% non breakable at production
19:12:55 <K> can you show a pic or something?
19:14:21 <Lemon> I guess it mostly depends on purity
19:14:38 <Lemon> and thickness of the end product
19:15:36 <hsn993> http://www.hammondmfg.com/pdf/1457N1202.pdf ^ i dont have the drawing yet .. but its small milling i want from back side
19:15:59 <hsn993> of the flange
19:18:14 <hsn993> i want to glue acrylic from behind for some led .. without breaking the IP rating of it
19:21:27 <K> if by flange you mean the end cap, then i cant see why this would be problematic tbh
19:22:09 <hsn993> yes .. the cap
19:22:31 <hsn993> they say it will break bcz its a casted material .. idk
19:23:08 <K> pff, i've milled some casted cases and it went fine
19:23:12 <K> was manual mill though
19:23:35 <K> but this looks less like actuall milling, more like router work
19:23:57 <K> i.e you just want to make hole(s) in it
19:24:33 <Lemon> yay two lil parcels
19:24:35 <Lemon> lets unbox
19:25:47 <Lemon> alright got the resistors for the divider in the 4 channels voltmeter
19:26:29 <Lemon> annnndd some nice protoboards !
19:27:33 <Lemon> 4 different sizes, great !
19:27:43 <Lemon> no more dead bug styles circuits hehe
19:27:54 <Ysjoelfir> nice :)
19:28:21 <hsn993> K , no i wanted to mill backside to put square acrylic for LEDs interface
19:30:47 <K> hsn993, do mspaint on sreenshot of that pdf where you want the milling
19:31:29 <Lemon> resistors I bought for the divider are 0.1% 15ppm/C vishays or dale, I dont remember
19:31:42 <Lemon> I need 4, so I'll be able to chose as I bought 10 of each
19:33:40 <Lemon> those protoboards or veroboards idk how they are called are neat for the price
19:37:33 <Ysjoelfir> Lemon, I remembered the other brand the 4mm connectors could be
19:37:50 <Lemon> ho I looked it up, they really looks like Staubli
19:38:05 <Lemon> thats cool I got a nice bag of them now :P
19:38:42 <Ysjoelfir> it could also be SEB6447AU/color from Schützinger
19:39:08 <Ysjoelfir> *6446
19:39:22 <Ysjoelfir> https://www.schuetzinger.de/files/seb_6446.pdf
19:39:55 <Ysjoelfir> yeah, as I said, the stäubli and the schützinger are basically identical, which is why we used both depending on availability
19:39:58 <hsn993> K, somthing like this https://snipboard.io/ahERCz.jpg
19:40:27 <hsn993> led hole + milling for acrylic glued
19:40:35 <Lemon> ha yeah I see
19:40:56 <hsn993> from front : https://snipboard.io/ZaRYGb.jpg
19:40:59 <Lemon> I should maybe use those instead of the chinese ones I bought, they say gold plated, looks like it but well I doubt it
19:41:38 <K> not quite router work, but close
19:41:51 <K> however, you cant mill square corners
19:42:34 <hsn993> sure .. that middle cut is not right dont care about it
19:42:56 <K> i'd make corners 6mm dia to keep machinist happy
19:43:19 <K> how thick is that wall?
19:45:03 <hsn993> 2mm from the cad
19:45:52 <K> uff
19:45:54 <K> that will be it
19:46:31 <hsn993> uff = good or bad ? xD
19:46:40 <K> it could be tricky to do a 1mm recess in 2mm thick wall
19:47:21 <K> would need some kind of jig to prevent the wall from flexing
19:47:24 <hsn993> so i should try to remove the milling part ?
19:47:51 <K> without milling it's just 2 holes, rigt?
19:48:02 <hsn993> yes
19:48:12 <K> yeah
19:48:42 <hsn993> but if i dont mill there is probablity that LED lens hit the acrylic sheet .. + it looks ugly from front
19:49:05 <hsn993> the hole with 2mm far acrylic sheet behind
19:49:27 <hsn993> or i can mill the acrylic to fit the hole ..
19:49:28 <K> welcome to mechanical engineering
19:49:59 <K> you'll have to ask your machinist about milling acrylic
19:50:23 <hsn993> ugly engineering ?
19:50:23 <K> not impossible
19:56:15 <Ysjoelfir> Just use 5mm LEDs, drill 4.8mm holes and SCHQUEEEEEEEEZE them into that ;P
19:56:33 <Lemon> I discovered that glueing leds with hot glue is a bad idea
19:56:41 <Ysjoelfir> true
20:01:26 <hsn993> ysjoelfir --> : https://photos.app.goo.gl/LnoSkmxdqWH1RYo36
20:01:40 <Ysjoelfir> oh
20:02:18 <hsn993> u can see how i screwed my self with the acrylic sheet ..
20:02:20 <hsn993> xD
20:03:11 <hsn993> first i should put the LEDs clearance with the connector and push them little bit more backward ..
20:03:37 <K> mill a spacer!
20:04:18 <hsn993> mill a spacer?
20:04:38 <K> if you have clearance issues
20:04:46 <K> was more of a joke though
20:07:45 <hsn993> ah

20:51:11 <Lemon> im tempted to get back to vape, instead of spending cash on cigs
20:51:17 <Lemon> not that it cost me a lot as I roll them myself
20:51:25 <Lemon> but I guess its a tad better
20:58:19 <Ysjoelfir> you should definitely do that
20:58:54 <Lemon> yeah and prices went down quite a bit, I still have a nice semi mech box, plenty of good cells, just need a tank and some good resistors
20:59:17 <Ysjoelfir> when you visit next time we can vape together. or smoke my selfmade shisha (did you know that they make vaping liquid based "tobacco" for shishas nowadays?)
20:59:32 <Lemon> yeah but im def not a fan of it :P
20:59:35 <Lemon> hehe sure !
20:59:57 <Lemon> the box I have is a tesla invader 3, this beast can go up to 240 watts xd
21:00:03 <Lemon> but around 100 is perfect for me
21:00:10 <Ysjoelfir> why not? I enjoyed it actually quite a bit. its not that scratchy as real tobacco, even SWMBO enjoyed it a bit
21:00:46 <Lemon> well idk I tried many tobacco flavoured juices, for ecigs or chichas but never quite liked it for some reasons
21:01:07 <Lemon> I prefer fruity thingies for vaping :>
21:01:16 <Lemon> or heisenberg, this one was nice
21:01:32 <Lemon> I think I'll get a TFV16
21:02:44 <Lemon> I didnt know you vaped :>
21:03:32 <Ysjoelfir> I was talking about fruity stuff^^ I dont like the taste of tobacco
21:03:43 <Ysjoelfir> but I have to admit that I like the smell of fresh tobacco
21:03:57 <Ysjoelfir> but not burnt tobacco. thats disgusting
21:03:59 <Lemon> ha alright ! yeah I like real tobacco :>
21:04:25 <Lemon> I have like 50 samsung 30q, I think they are good enough
21:04:29 <Lemon> the box I have uses two of them
21:32:31 <Ysjoelfir> GREAT! right when I thought that my money situation finally gets a bit better the health insurance calls, telling SWMBO that they paid too much money since 2017 for her CPAP device, and now wants to have back 2700€. wtf?

22:27:24 <Ysjoelfir> where was that?
22:27:31 <K> somewhere in .no
22:27:46 <Ysjoelfir> well, I assumed that since you wrote "meanwhile in norway" :P
22:28:36 <Ysjoelfir> its actually pretty funny to see that sad house float around like a bath toy, even though I feel sad for those that lost their property

23:18:29 <hsn993> at the beach
23:20:29 <Ysjoelfir> nice
23:21:34 <hsn993> dude how do u do this stuff :
23:21:56 <hsn993> https://snipboard.io/4XV3Qz.jpg
23:22:29 <hsn993> there is other pcb that i want to put here without collosion the connectors which goes into each other
23:23:26 <Ysjoelfir> rules - add a new collision rule with a priority higher than the standard one and specify it as "where the first object matches *the first PCB* and the second object matches *the other PCB*"
23:24:21 <hsn993> ok so u just make it ignore
23:24:23 <hsn993> ?
23:25:01 <Ysjoelfir> well, I make it ignore each other, as it... is touching. so what else yhould you do?^^
23:25:21 <hsn993> ok .. its same as (component clearance) right?
23:27:01 <Ysjoelfir> it IS component clearance IMHO
23:27:18 <Ysjoelfir> I don't have altium in front of me, so I can't check, but IÄm pretty sure
23:27:26 <Ysjoelfir> T3sl4 - I'm sure you know it off hand
23:28:51 <hsn993> no problem .. but the second object is not compoentns
23:29:01 <hsn993> i just (placed -> 3d object -> step file)
23:29:09 <hsn993> so i cant filter it in the rules right?
23:30:17 <hsn993> unless i give it a class i guess

23:42:04 * K is about to eat his dinnerbread.
23:42:23 <K> and all is quite well
23:42:42 <canadaguest> I see
23:43:07 * canadaguest is ok this mid-morning here. just trying to narrow down choices of companies for one thing atm
23:43:23 <K> bread?
23:44:55 Join: Lemon ([email protected]) to #EEVblog
23:45:03 <Lemon> weeee two other parcels
23:45:15 <Lemon> theres a good thing about ordering tons of cheap things lol
23:45:32 * Ampera licks Lemon
23:45:37 <Ampera> how do fren
23:45:52 <Lemon> hmmm I prefered to be squeezed xd well good good and you ?
23:46:01 * Ampera squeezes Lemon
23:46:10 <Ampera> I'm alright I guess
23:46:12 <Lemon> perfect !
23:46:26 <Ampera> I managed to get Linux to mount root off NVMe on my pinebook pro
23:46:35 <Ampera> so it boots off eMMC, but actually runs off NVMe
23:47:01 <Lemon> with clover bootloader ? :>
23:47:11 <Ampera> nope, das u-boot
23:47:43 <Lemon> ha ok ! im doing something similar with a usb key on my workstation, nvme arent supported by the mobo, but this little thing was a gamesaver
23:48:09 <canadaguest> k nope no bread .. its more to do with that I want find some vehicle-friendly electroclutch
23:48:16 <Ampera> On x86 it'd be trivial as I can easily regenerate the bootloader configs, and I don't have to deal with complicated positions and whatever else
23:50:16 <Lemon> shit, im realizing something for the 4 channels voltmeter
23:50:35 <Lemon> the tft screen is taking all the inputs on the arduino
23:50:40 <Lemon> and I need a few
23:50:54 <Lemon> rahhhh damn thats so dumb
23:52:59 <canadaguest> k basically lets say I wanted to be able to control it from a simple toggle switch on dashboard. so mechanical is out of question and I don't know about using fluid, that so far seem to leave me with perhaps electroclutch
23:53:26 <canadaguest> lemon sorry if I may be a bit silly, but what does a voltmeter need tft for?
23:53:38 <Lemon> well display voltages ? :>
23:53:42 <K> sounds expensive, canadaguest
23:53:47 <Lemon> its a tiny tft
23:53:48 <canadaguest> lemon and you can't do that with character display? :)
23:54:05 <Lemon> the thing is, theres 4 channels, and I wanted it to be lisible
23:54:09 <hsn993> hello canada :>
23:54:11 <canadaguest> k a little maybe but its cheaper than a burnt out motor
23:54:11 <Lemon> so I saw those 6 euros tft's
23:54:27 <Lemon> but didnt realize they are taking every pins on the arduino
23:54:37 <Lemon> but maybe theres a chance, as those are tactile, and I dont need that
23:54:39 <hsn993> weather is pretty good .. around 40C
23:54:42 <Lemon> maybe some pins are used for that
23:55:23 <hsn993> which tft lemon
23:55:36 <hsn993> i2c or spi ?
23:55:42 <hsn993> to get less pens ?
23:56:16 <Lemon> pfff I dont even know I gotta check
23:56:54 <Lemon> https://www.ebay.fr/itm/3-5-inch-480x320-TFT-LCD-Touch-Screen-Display-UNO-R3-Board-For-Arduino-Mega2560/392479411746?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
23:57:47 <Lemon> ha wait
23:57:55 <Lemon> I might be able to do it
23:58:02 <Lemon> theres a sd card reader for some weird reasons
23:58:13 <Lemon> I dont need that, as it will connected via usb to a computer, if needed
23:58:43 <Lemon> that leaves me pins 10 to 13
23:58:51 <hsn993> i dont know which one is this but the code seems like its SPI one
23:59:17 <hsn993> so u dont need to use all the pins .. they are just to stack it on top of the arduino
23:59:24 <Lemon> I just need some pins for a few buttons and to connect the adc module
23:59:30 <Lemon> yeah exactly
23:59:32 <Lemon> thats fine
23:59:48 <hsn993> but then the table of pins doesnt fit with the code
23:59:50 <Lemon> LCD D0 to D7
23:59:57 <Lemon> idk what are those
