10:44 <rust_collector> Ysjoelfir are you busy-busy?
11:09 <Ysjoelfir> I am at least at the PC
11:18 <rust_collector> ok
11:35 <Ysjoelfir> no idea if that makes me a busy ys :D
13:51 <rust_collector> well, I think I will have some homemade bread with roast beef, let me know if you figure it out
14:51 <Ysjoelfir> haha :D Nah, what can I do for you? I am working away here, but I am free to react to stuff while doing so.
15:01 <hsn> Halcyon, why u think of me .. love <3 :D
15:40 <hsn> that was 3 hours ago
15:45 <hsn> hmm
15:58 <hsn> Ampera, u minor
16:04 <hsn> minority
16:31 <hsn> rust_collector, apetit they say ? i forgot
17:08 <rust_collector> ape-titt
17:19 <rust_collector> Ysjoelfir I am bored, entertain me, lol
17:35 <hsn> sudo ape-titt rust_collector
18:08 * rust_collector monkey-peeks on hsn 
18:18 <hsn> stop monkeying around
18:21 * Ampera sneezes all over hsn, coating him in a veritable snot bukakke
18:37 <hsn> Ampera, im immune
18:43 <Ysjoelfir> erm..... watch hsn google Bukkake, rusty :D
18:56 Quit: Kuschelpony ([email protected]) Connection closed
19:06 <rust_collector> nah, I think that is fairly common down in sand-land
19:29 <Ysjoelfir> you think so? I thought it was more an asian thing
19:45 <rust_collector> it is, they have a different name for it
19:50 <Ysjoelfir> oh
19:59 <hsn> Ysjoelfir, https://snipboard.io/U1uMc0.jpg
20:01 <rust_collector> and they use camels
20:18 <Ysjoelfir> lol
21:15 <hsn> nsfw ?
21:19 <Ysjoelfir> yes
21:24 <Ysjoelfir> very much not :D
21:32 <hsn> EEVBot, warn NSFW enable for hsn
21:33 <rust_collector> not for your job...
21:34 <EEVBot> hsn: nega-tory, ghost rider!
22:07 <rust_collector> EEVBot is still negative
22:08 <EEVBot> rust_collector: nega-tory, ghost rider!
22:12 <rust_collector> right
22:17 <Ysjoelfir> EEVBot is always negative
22:18 <EEVBot> Ysjoelfir: nega-tory, ghost rider!
22:20 <Ysjoelfir> he doesn't like us
22:30 <rust_collector> EEVBot is full of hate
22:31 <EEVBot> rust_collector: nega-tory, ghost rider!
22:34 <Ysjoelfir> its the reincarnation of mr. heads soul
22:37 <hsn> i think EEVBot camelSay is a must .. do u agree rust_collector ?
22:38 <rust_collector> yea
23:02 <rust_collector> add more crap to it, so I can go back to just blonking it again
24:09 <hsn> i think urban is nice command to have
24:16 <hsn> EEVBot, urban <word>
24:17 <EEVBot> hsn: nega-tory, ghost rider!
24:17 <rust_collector> urban turban
26:34 <rust_collector> what is the thing with short videos on ebay these days?
26:41 <rust_collector> or youporn
26:44 <rust_collector> google
26:50 <rust_collector> that video place
26:55 <rust_collector> you...something
27:22 <hsn> oh
27:35 <Ysjoelfir> you mean DuPiper?
27:38 <hsn> that red thing
27:42 <hsn> ?
27:49 <rust_collector> yes! the red one
27:52 <rust_collector> redtube
28:14 <rust_collector> no wait
28:22 <hsn> ted talks
28:33 <hsn> netflix
28:35 <rust_collector> bill and ted talks
29:25 <hsn> you t u b e ?
30:00 <rust_collector> i forgot what you people was asking, I have no idea
30:27 <hsn> u think we ask ?
30:31 <hsn> nice of u
30:34 <hsn> we only troll
31:00 <rust_collector> you don't have trolls down there... they can not be outside in the sun
32:49 <hsn> we troll in shade
35:12 <K> hsand
39:38 <hsn> my name
40:24 <hsn> (imdb) my name is hsan
42:59 <rust_collector> hahaaaa, maybe I don't have to go pick up the onion van again. at least until I have less time to do it
53:23 <Ysjoelfir> hsn, T3sl4, whats your favorite n channel FET that can be used to switch 12V 5A heaters (pulsed) with a 12V drive voltage in a "usefull" smd package? Basically I am looking for a modern SMD equivalent to the good old IRF530
53:48 <T3sl4> NDT3055?
53:53 <T3sl4> wait, not 5A
57:58 <Ysjoelfir> hmm?
01:07 <hsn> Ysjoelfir, oversized ? https://rocelec.widen.net/view/pdf/mnidndpudj/ONSM-S-A0002314931-1.pdf?t.download=true&u=5oefqw
01:08 <EEVBot> [Title] - ONSM-S-A0002314931-1.pdf
01:37 <Ysjoelfir> I have no problem with oversized stuff, as long as its reasonably priced and works reliable
02:07 <hsn> ah the min. qty
04:01 <rust_collector> if he would finish his list of stuff not needed, he would have room for a large bucket of tiny oversized fets
04:07 <hsn> anything automotive im in love with :D
04:51 <rust_collector> those fets they use as diodes in the start booster things tend to have pretty amazing specs
04:54 <hsn> https://assets.nexperia.com/documents/data-sheet/BUK9Y153-100E.pdf
04:55 <EEVBot> [Title] - Access Denied
05:35 <hsn> Ysjoelfir, how do u know which gate capacitance u should watch
05:44 <hsn> QGD ?
06:45 <Ysjoelfir> in my case its not realy relevant, as I have enough drive power. but if I would drive it with something different I would look for that
07:21 <hsn> drive speed = slow ?
07:36 <hsn> too much fast switching = too much heat?
07:59 <hsn> "fast = reputative , but slow rise time" .. hmm im shit at describing
08:00 <K> i used this - https://www.infineon.com/cms/en/product/power/mosfet/12v-300v-n-channel-power-mosfet/bsc020n03ls-g/
08:05 <EEVBot> [Title] - BSC020N03LS G - Infineon Technologies
08:06 <K> BSC020N03LS G
08:10 <Ysjoelfir> that depends how fast you can/do charge that gate.
08:14 <Ysjoelfir> yes
08:25 <K> for pwming peltier 12V / 10A max
08:37 <K> did have to put in a driver ic though
08:53 <K> pwm freq was 250kHz?
09:05 <hsn> that has 70nC gate thing
09:06 <K> something like that
09:12 <Ysjoelfir> K, that one looks not bad, but I struggle with those PowerXYZ packages. THey always look a bit like a compromise to me
09:24 <hsn> K, why not 10KHz .. isnt that better ?
09:30 <K> larger inductor
09:36 <Ysjoelfir> I am a realy big fan of DPAK, but... I think I should go with the time :D
09:53 <hsn> K, so peltier was drivin with no pulses .. but filtered DC ?
10:02 <K> ye
10:16 <hsn> why no pulses directly :D .. exuse my questions
10:26 <K> peltier is pn junction
10:35 <K> more losses when switching
10:52 <hsn> fck loses if it works :D
11:01 <K> nah, i was fighting heat inside enclosure
11:18 <hsn> and with this 75nC fit all good ?
11:18 <rust_collector> hmm, so, if you were using them for heating....
11:27 <K> with driver ic it is fine
11:31 <hsn> rust_collector, i had that idea :D
11:43 <K> driver ic - MCP1416
11:57 <K> prolly there is someting cheaper too
12:06 <K> didnt care at the time
12:37 <Ysjoelfir> I wanted to try out the UCC2751x as a cute little gate driver.
12:40 <Ysjoelfir> https://www.ti.com/lit/ds/symlink/ucc27517.pdf
12:47 <K> now the only thing heating up there is the diode
12:58 <K> could've gone with some synchronous approach, but eh
13:04 <K> next time
14:31 <hsn> thermal model has thermal capacitor
14:33 <hsn> lel :D

15:54 <hsn> No
16:07 <rust_collector> digikey up here works
16:18 <hsn> Ur link works
16:19 <Ysjoelfir> hm, seems like the bot sees it as well?
16:21 <Ysjoelfir> [17:15:52] <+EEVBot> [Title] - Site Connectivity Issues
16:32 <Ysjoelfir> yes, but try to modify the search
16:37 <rust_collector> and your link works
16:53 <Ysjoelfir> lol, works again. meh
17:00 <Ysjoelfir> thanks digikey for making me look stupid
17:48 <hsn> Dont worries .. u r stupid before the link .. joke i hope not offensive ? Is it? Damn im sttupid
17:56 <Ysjoelfir> no, its not :D
18:09 <hsn> Good
18:15 <hsn> Now time to leave for weekend
18:18 <Ysjoelfir> well, it would be if I wouldn't know that we are here always joking^^ but since I know that, its all fine :D
18:29 <Ysjoelfir> weekend?
18:47 <Ysjoelfir> oh wait, you have friday and saturday off and need to go on sunday to work, right?
18:51 <rust_collector> that is the way they do it down there
18:59 <rust_collector> weirdos
20:10 <rust_collector> they like to have the friday off, so they can get together in the square, and watch the canings and stonings. and on special days beheadings and hand chopping
20:43 <rust_collector> then go to the beach and have a bbq....
22:15 <Ysjoelfir> bbw sounds like a plan
22:52 <Lemon> so I asked LMT about the luxmeter I bought, and the guy was quite nice, he managed to find a document about it ! its not a detailed one, but it gives a few infos, and it seems to be quite an accurate device !
23:21 <Lemon> on top of making leds blink, I'll be able to tell you if they blink correctly now !
23:25 <Lemon> yeyyyyyyyy
23:26 <hsn> Right
24:04 <Lemon> well, that is if the guy ever post it lol
24:15 <Lemon> but he will, im sure, he was quite a good peep at the phone, for once
24:20 <Ysjoelfir> my Systron Donner is already on its way
24:21 <rust_collector> does not matter, you own one of those things
24:49 <rust_collector> and it saves space in your place, if he never ships it
24:58 <hsn> Yes Ysjoelfir I only joke like that with close friends
25:04 <Lemon> Ysjoelfir damn ! I want leboncoin to be as good
25:20 <Lemon> rust_collector well no thats my first luxmeter :>
25:52 <rust_collector> right, so you save time learning how to use it also, this is just win win win
25:57 <Ysjoelfir> I know hsn :) so its fiiiiine^^ Lemon, well... I have been waiting for my spark distributer for the volvo for 2 weeks now, and the guy just told me he "forgot" to send it. so.... its not that much better :P
26:07 <hsn> https://photos.app.goo.gl/2NeKg5fuGfgkMSKD7 bye
26:24 <Ysjoelfir> its weeeeekend hsn!

27:33 <Lemon> heh at least they end up sending them xD its so annoying to find a good deal, buy it, for the guy to say " I dont accept delivery and online paiement" :(
27:47 <Lemon> im still a bit sad about the 20 euros keithley, or the fluke 8800a, or many others...
28:12 <Ysjoelfir> that seems to be a french thing than, Lemon
28:46 <Lemon> frenchies are horrible with internet, or technology in general (consumer side, that is)
28:52 <Lemon> well, pro side Idk either
29:30 <Lemon> so im consolating myself with amazon !
29:31 <Ysjoelfir> I think I try the BUK7277 https://assets.nexperia.com/documents/data-sheet/BUK7277-55A.pdf
29:32 <EEVBot> [Title] - Access Denied
29:48 <Ysjoelfir> cheap, looks like a nice part, DPAK, what is there not to like
29:48 <Lemon> today I bought this, to replace my collection of shitty helping hands

29:53 <EEVBot> [Title] -
30:21 <Ysjoelfir> Lemon, I have a simmilar thing. I realy love those ball swivel mounts
30:31 <Lemon> good, thats what I want to hear !
30:36 <Ysjoelfir> but mine is waaaaay older, and a "regular" vise thing
30:36 <Lemon> it looked perfect
30:48 <Lemon> yes I wanted one that clamps on the desk, so im sure it doesnt move
30:55 <Lemon> newer ones might be too light, or idk
31:06 <Lemon> and it seems it can clamp decently sized pcbs, too
31:18 <Lemon> we'll see tommorow :> im starting to be quite set !
31:32 <Lemon> I need to find a good electronic mega book and start it
31:35 <Ysjoelfir> want me to make a pic of mine, Lemon?
31:39 <Lemon> yes !!
31:45 <Ysjoelfir> ok, gimme a sec
31:50 <Lemon> and a pic of your current lab, if you can :P
33:10 <Ysjoelfir> I do that for you when I am done cleaning it again XD which will be this weekend if everything goes to plan
35:21 <electrohead> o/
35:23 * electrohead yawns
35:35 <rust_collector> great idea, electrohead
36:01 <electrohead> EEVBot: slap rust_collector
36:02 * EEVBot viciously slaps rust_collector with an enormous smelly trout
36:27 <rust_collector> why do I always get a trout?
36:39 <Ysjoelfir> Lemon https://drive.google.com/file/d/16UQ0uGa7G93q8AWIgUIdHOZrJaHQ2hRb/view?usp=sharing
36:40 <EEVBot> [Title] - 302 Moved
40:02 <K> coz you like it and we know that
40:52 * Ampera hugs electrohead 
42:41 <Lemon> Ysjoelfir ha but it does clamp on the desk too !
42:43 <Lemon> very nice
43:08 <Ysjoelfir> yep. thats pretty usefull for.... various things actually
43:52 <Lemon> well you could add some rubber on the biting thing (vice ?) with stries to hold pcbs
44:19 <Ysjoelfir> I already added rubber. but for PCBs I have this cool weller PCB stand thingemajig
44:25 Join: Guest69 ([email protected]) to #EEVblog
46:16 <Lemon> I see :> a cool system I saw, was with a a4 or bigger thin metallic plate, various stands that sticks with magnets to it
46:23 <Lemon> and you can clamp your pcbs or whatever
46:45 <Lemon> and they also sell extensions with little probes, so you can probe wherever you want on your circuit
46:51 <Lemon> as they have pogo pins, it holds well
47:30 <Ysjoelfir> ah yes, I saw that one.
48:22 <rust_collector> for pcb work, you probably want a forged one
48:54 <Lemon> you want all the things, rusty
48:55 <Lemon> all the things
49:03 <rust_collector> yes you do
50:23 <Lemon> if it was expensive before and now cheap, I want it
50:35 <rust_collector> we know
51:09 <Lemon> its not even my final form !
53:34 <Lemon> you know im not a fan of uni-t brand, but I must admit their thermal camera 260B something looks really good
53:53 <Lemon> some people owning kilobucks models said its really fine
54:05 <rust_collector> they have plenty of good enough for most things things.
56:44 <Lemon> it seems they are making better products than before yeah, I remember seeing tons of test where various things they made were shitty, with bugs, or just really crappy even for the price
56:52 <Lemon> but I saw a couple newer ones that are actually good
57:31 <Lemon> well I'd always prefer a used known-brand one to a new uni-t dmm for example, but the 61t something looks nice
57:54 <rust_collector> my little uni trend pocket meter is just so cute, that I don't care if it works or not. But it does seem to be pretty ok
58:36 <K> does it cuddle?
58:50 <rust_collector> no, it is not annoying like that

21:10 <Ysjoelfir_> did you see the youtube channel I linked you iirc yesterday? might be a good time killer
22:00 <rust_collector> uh, no.
22:19 <Ysjoelfir_> https://www.youtube.com/c/Rolingmetal
22:32 <Kuschelpony> hmm, i might have seen the link but as i generally dont watch videos at all to not hurt my brain, i might have just ignored it, pleqase excuse

26:18 <rust_collector> hmmm, yeas, I shoudl look thru that
27:46 <Kuschelpony> btw:
28:05 <Kuschelpony> if you want to check your bass reflex tuning i recommand this track
28:06 <Kuschelpony> python ./youtube-dl -f 18 5DBc5NpyEoo
28:48 <Kuschelpony> this goes somewhat deep but very "dry" so any underdamped resonance is vell audible
31:13 <rust_collector> and it is a good tune anyway
32:42 <Kuschelpony> not my primary taste as i am more in specific kinds of 80s rock, but i have a secondary taste for some non-dancefloor-synthesizer pieces
33:01 <rust_collector> yep
34:09 <Kuschelpony> i miss Roxette and their early tunes, like "Physical fascination"
34:20 <Kuschelpony> some like the Scorpions are still around
35:23 <rust_collector> i want to see them now, because I wonder what a new drummer will do to them
37:19 <Kuschelpony> im curious
43:51 <Kuschelpony> until then Scorpions - Holiday (Rockpop In Concert, 17.12.1983)-d5Hd7lfQcWY

00:43 <Lemon> check this guys
00:46 <rust_collector> wheeeeee!
00:57 <Lemon> not that I want it, but im super curious on how good it is
01:02 <Lemon> for 145 euros
01:06 * Ampera sets fire to a bucket of water, places it in the middle of the channel, huddles around it
01:07 <rust_collector> is it ok
01:37 <Ampera> no it is a bucket of water
01:47 <Lemon> its so slim lol
02:00 <Ampera> no it's a bucket of water
02:06 <rust_collector> Lemon it uses an external power brick
02:14 <Ampera> no Lemon is a Lemon
02:18 <Lemon> I see
02:19 <rust_collector> Ampera it is a hit bucket of water
02:27 <rust_collector> or hot
02:30 <Ampera> don't hit my bucket of water
02:32 <Ampera> it is on fire
02:34 <Ampera> you will be on fire
02:42 <Lemon> 145 euros for a 100Mhz, 1Gs/s scope with a built in 2Mhz arb gen, thats unseen
02:46 <rust_collector> meh. it happens
04:04 <coppice> if you enter a crowded market you need to be exceptional - either exceptional in performance, or exceptionally cheap
04:17 <Ampera> or exceptionally horny
04:45 <Lemon> yeh ofc but I wonder how good it is for that price
04:52 <Lemon> it does look cheap, for sure
04:59 <coppice> I'm not sure I'd buy a horny oscilloscope
05:12 <rust_collector> sure, it is cheap, but it is not total crap, says the youtube. I don't know, or care, really
05:22 <Ampera> coppice, what if it had vibrating probes
05:42 <coppice> Ampera: the female engineer market is really small
05:58 <rust_collector> and why do you think that is?
06:21 <Ampera> rust_collector, buying female engineers, or in general any women, is usually frowned upon
06:21 <coppice> very few women like the work
06:38 <rust_collector> and your probes don't vibrate
08:41 <coppice> If your probe vibrates you probably need a course of levo-dopamine
10:34 <Lemon> I think I'd still prefer a used tektronix or alike
10:42 <Lemon> like a tds 210, you can find them for that price
11:38 <Lemon> the ones I like are micsig tablets, but version with physical buttons
11:42 <Lemon> they are far from cheap tho
13:42 <Lemon> they also make nice differential probes/current probes
30:13 <Lemon> anybody is using active probes here ?
30:18 <Lemon> I have a few questions regarding those
32:46 <Lemon> I read many things on scopes, like for example with a 100Mhz scope, you wont be able to look at 100Mhz signals, it will be attenuated so its good to have multiple times the bandwith of what you want to look at
33:05 <Lemon> about active probes, from what I understand, its mostly for low level signals, and its much more accurate than passive probes
33:15 <Lemon> you also need a short ground loop
33:45 <Lemon> with my tds 540 you could buy a 750Mhz fet probe, but I guess a 1Ghz would be better, right ? (double the max bandwith)
36:44 <Lemon> they are quite cheap for an active probe https://www.ebay.fr/itm/324042471552?hash=item4b726fb880:g:vloAAOSwz6NeF33w

10:40 <Lemon> I like that tds 540
10:54 <Lemon> the thing I fear is when I'll need to replace caps, because they die in those, from what I read
11:04 <Lemon> and the lines fading on the screen is probably due to that
11:12 <Lemon> not a huge deal
11:37 <Lemon> also, since I have it, the compensation (that 1Khz square wave gen to compensate probes) doesnt work properly at all
11:46 <Lemon> I have the same issue on my portable tek
11:52 <Lemon> maybe its also due to caps, no idea
15:23 <Lemon> that little 2Mhz centrad gen is also ok, square waves start to look meh past 1Mhz tho

11:13 <MrMobodies> Hello
11:25 <MrMobodies> Anyone using firefox and any problems with extensions breaking?
11:27 <steve30> hi
11:43 <rust_collector> moin moin
11:58 <rust_collector> no, they work great here. both 3 of them
12:12 * steve30 doesn't use firefox
14:41 <MrMobodies> I had to disable the auto update on the extensions
14:45 <MrMobodies> it hasn't broken sinx
14:47 <MrMobodies> since
15:31 <MrMobodies> I am trying to make it in such a way I can run Firefox 22, 78ESR, 88 and any future releases side by side.
17:00 <rust_collector> ok, but whyyyyy?
23:39 <MrMobodies> side by side
23:49 <MrMobodies> took me all last night
24:03 <MrMobodies> well I use the Firefox 22 for older routers and stuff I still have running
24:12 <MrMobodies> where webpages don't seem to work too good
24:19 <MrMobodies> on newer browsers
25:01 <MrMobodies> and when I don't like something in the next/current release, I'll label it, copy the program into the browserprofile, map the profile and wait until I find a solution
25:16 <MrMobodies> so it is all organised
25:35 <MrMobodies> I run many profiles with chrome stuff
28:50 <MrMobodies> https://i.imgur.com/wnpoRpv.jpg
29:07 <MrMobodies> I use a combination of browsers for all sorts of things but gave up on firefox last year for a while
29:31 <MrMobodies> and most of the profiles are isolated
29:50 <MrMobodies> so when I look for drills on amazon they won't appear on some advert on ebay
30:04 <rust_collector> heh, what is the duck extension?
30:06 <MrMobodies> and i can stay sign in without worrying about session hijacking
30:21 <MrMobodies> it hides the fixed/sticky headers

30:48 <arch> im reading a TI appnote which says: "The larger the inductor value, the smaller the inductor ripple current and the lower the conduction losses of the converter". shouldn't it be HIGHER conduction loss due to higher inductance? more windings on the coil = more resistance
31:31 <arch> they prob meant core losses would be lesser

33:07 <arch> lol, for yahoo i just blacklist all the domains their adservers use on my router hosts
33:22 <arch> peace and quiet...also, disable autoplay on firefox
33:28 <arch> html shitty ass autoplay garbage

38:46 <MrMobodies> the autoplay garbage I use something called hide HTML5
38:51 <MrMobodies> but that doesn't seem to work anymore
39:03 <MrMobodies> actually vivaldi has controls for that
39:05 <MrMobodies> let me check
40:40 <MrMobodies> https://i.imgur.com/Sm1b64i.jpg
40:42 <MrMobodies> yes it does
40:46 <MrMobodies> and it is set to off
40:52 <MrMobodies> isn't that nice?
41:48 <MrMobodies> that's why I notice many preloading spinners (well I added many similar words up in my blocklist)
41:55 <MrMobodies> oopops *I don't notice
42:55 <MrMobodies> unfortunately the extensions don't seem work in the play store or chrome bugs website as they are considered "privileged pages"
43:13 <MrMobodies> where no extensions work apparently past I think Chrome 69

51:41 <rust_collector> those are great
51:46 <rust_collector> probably
51:59 <Lemon> heh 1 is already nice I guess
52:07 <Lemon> I wanted to buy a few different ref, not too expensive
52:12 <Lemon> and try them
52:31 <Lemon> this one is interesting as it outputs +10, -10V or 5/-5 etc
54:02 <rust_collector> and input is? and how much current can you get out of it?
54:45 <Lemon> 10ma, if I read it right
54:58 <rust_collector> mkay
55:00 <Lemon> but it doesnt really matter as I'd use it as a calibration device
55:09 <rust_collector> sure, just wondering
55:22 <Lemon> it looks complicated to use compared to others
55:33 <Lemon> its not a simple temp compensated zener
00:49 <Lemon> lots of kits use the 584, which offer 10, 7.5, 5 and 2.5v outputs
00:54 <Lemon> but its much less accurate

25:20 <T3sl4> thermocopupper?
25:41 <Ysjoelfir> argh :P you know what I mean
25:51 <T3sl4> from what metals?
26:12 <T3sl4> if you have the standard alloys just twist/weld them together, s'fine
27:16 <Ysjoelfir> I have no idea. just had an idea in my mind. you know from that motorcycle heater thing I am working on. right now it has 4 wires, 2 for the heater and 2 for a NTC. I wondered if I could make it easier by just adding a small homemade thermocouple in line to the heater, basically like JBC does it in their soldering irons
29:15 <T3sl4> sure, why not
30:13 Join: Lord_of_nothing ([email protected]) to #EEVblog
31:02 <Ysjoelfir> my "fear" was, that I will get into devils kitchen (is that even a set phrase in english?) and have to calibrate each and every heater/TC combination to each specific unit. I THINK as long as the materials are the same all the time it should turn out with the same voltage each time, but is that the case?
32:21 <T3sl4> probably? idunno
32:32 <T3sl4> it's not like you need mK accuracy
32:52 <Ysjoelfir> nono, definitely not. but it would be bad if the left heater was 10C warmer than the right one or stuff like that
32:53 <T3sl4> if it's going to be out by 10K is the question
34:17 <Ysjoelfir> I think I should keep that idea in mind for a second revision.
34:46 <Ysjoelfir> it SHOULD work out good I think
39:40 <T3sl4> mind that the thermocouple needs to be heatsinked well, to minimize self heating
39:55 <T3sl4> in turn to minimize dwell time between heat pulses, in which to make the measurement
44:20 <K> how about puuting high value ntc parallel to the heater?
45:15 <K> (or two)
46:59 <Ysjoelfir> T3sl4, it will be potted in heat transfer epoxy very close to the heater cartridge, so it should be pretty close to the temperature of the heater itself.
47:25 <Ysjoelfir> K - I'm not quite sure I get the idea. That would resolt in a 4 Ohms heater parallel to eg 100k?
49:01 <K> well, if you know nominal current through 4 ohms, then 100k ntc will shunt some away
49:13 <K> hopefully enough for you to notice on the other end
49:38 <Ysjoelfir> hmmm.... thats actually not a bad idea, I should calculate that
50:03 <K> problm with self heating is still there though
50:11 <T3sl4> meh, tolerance and tempco of the heater is probably much more significant than that
50:18 <T3sl4> i.e. it'd be just about impossible to cal out
50:28 <T3sl4> if you can, though, yeah, it would work
50:46 <Ysjoelfir> yeah, thats what I assumed.
50:50 <K> put a ntc on a ntc!
51:00 <Ysjoelfir> xD
51:08 <T3sl4> the flip side of that is make the whole thing a PTC, say with Ni or Fe wire or whatever
51:32 <T3sl4> then you need a known good alloy, or a calibration step, but it should be consistent
51:37 <K> put in both and let them fight it out
51:46 <Ysjoelfir> That would be possible, but way more work than just using premade 3d printer cartridges for 1€ each
51:50 <T3sl4> again, downside is temp rise between wire and, whatever part of the handle/core you're actually interested in measuring
52:10 <K> in the end 4 wires will be just fine
52:18 <T3sl4> and those i'm guessing use nichrome? so, not a great tempco
52:24 <K> can you get away with 3?
52:32 <T3sl4> 3 would be fine yes
52:51 <Ysjoelfir> well... I thought so, K, but the potential customers were like "meeeee, even four wires (for 2 handles) is already pushing the limit!" XD
53:04 <Ysjoelfir> but yes, I could make it work with 3 per handle, thats not a problem
53:31 <T3sl4> although 3 you still need to mind self heating or drop along the common wire, so likely need to stop heating to take a measurement
53:53 <T3sl4> not quite as bad as the direct heating in the 2 wire case, but not as good as fully independent
55:44 <K> induction heating with those funny feromagnetics!
55:48 <Ysjoelfir> hmhmhmhmhmmm..... so many possibilities.
55:50 <Ysjoelfir> lol :D
56:30 <K> like they do with fancy soldering irons
57:07 <Ysjoelfir> pace?
57:18 <K> yea i think
58:04 <Ysjoelfir> never tried one, they are basically made from unobtainium here in germany
58:25 <T3sl4> i mean, if it's always inside a steel tube handle, it would do a fine job
58:37 <T3sl4> the interesting thing is if you can get a measure of temp from the impedance
58:59 <Ysjoelfir> yeah, but you can't know that, as aluminium handles are pretty common nowadays
59:21 <Ysjoelfir> BMW even released a bike with carbon frame, so I think carbon handles will be there soon as well
00:53 <T3sl4> meh, just crank up the frequency, eventually you'll get some heat directly into the meat tongs
01:01 <Ysjoelfir> xD
02:46 <K> super effective!
03:09 <K> you could add a mic and detect when the driver starts to scream
03:24 <Ysjoelfir> lol :D overload protection? XD
03:32 <K> "that is prolly warm enough"
05:00 <Ysjoelfir> "just a bit more..?" - *screams qagain* - "nope, thats fine"
05:24 <K> PID loop yes
05:51 <Ysjoelfir> acquisition of PID parameters by experimentation, works all the time!
06:08 <K> some calibration will be needed
07:24 <Ysjoelfir> bwahaha :D Mr. Cat was in the chair behind me, as he likes to be.... I forgot that he is there and had to fart.... suddenly there was a very rapid movement behind me xD
11:53 <K> haha

48:59 <Lemon> this night I was looking up prices for a new battery, for my THS710a (it was my fathers portable scope/dmm, a super nice device, but battery is long dead)
49:12 <Lemon> they were always around 120-130 euros, so I never replaced it
49:26 <Lemon> but surprise, now you can find one for 38 euros !
49:45 <Lemon> and on top of that I recently found one isolated probe for it, the second is sadly damaged
49:58 <Lemon> so I think I will splurge for one and make it live to its fullest again
51:08 <Ysjoelfir> Halcyon, that looks tasty. I take four

11:58 <Lemon> you finally figured it out ? I tried with my 540, only thing I managed to get was "read" what was outputed with keysight IO thingie
12:19 <T3sl4> Lemon: it works with my adapter thingy anyway
12:23 <Lemon> and it wasnt really a picture, just a string of weird thing that was reapeating always the same
12:42 <T3sl4> like i said, idunno what your driver/library chain thingy is doing
12:53 Quit: modrobert ([email protected]) Ping timeout: 121 seconds
13:48 <Lemon> yeah your diy adapter is super nice !
14:11 <Lemon> and the flickering when you click on hardcopy is also on mine, btw
14:17 <Lemon> I saw you asked about it
14:41 <hsn> K: ill come back later its not right time now .. but all i can say there wad a pedo story with some relative
15:00 <K> hrm :/
15:02 <T3sl4> ah
15:22 Quit: MRiddickW ([email protected]) Ping timeout: 121 seconds
15:24 <T3sl4> maybe you got the right data then, and just need to put it into the correct file format?
16:55 <Lemon> well I guess but what is weird is when I carefully look at the output, its a repetition of the same string
17:07 * Ampera plugs a tan wave inverter in
17:21 <T3sl4> most of the data are periodic because graticule lines etc
17:32 <Ampera> my mom always said I had infinite potential
17:49 <Lemon> so you'd say its normal ?
18:02 <T3sl4> Ampera: you're also flipping rapidly between positive and negative
18:35 <Ampera> I'm just adhering to whatever's current
22:15 <Lemon> on my tds 540 theres also a weird thing, the compensation 1Khz thingie seems shot
22:25 <Lemon> impossible to get something out of it, besides an error
22:35 <Lemon> its also wonky on my ths710a
23:21 <T3sl4> Lemon: open this in a hex editor, https://www.seventransistorlabs.com/Images/circle.bmp there's a block at the start, with "BM" and mostly 0x00000000's with some other numbers, for the header, then a bunch of ff's for the bottom rows (white empty space), then some junk for the bottom text, and then it gets fairly periodic
24:14 <Ampera> That's an interesting botanical mystery I might have just solved
24:18 <rust_collector> Ysjoelfir don't you need 2 of these things? https://www.finn.no/bap/forsale/ad.html?finnkode=218502432

24:28 <Ampera> I've always seen these little red/green berries (tiny thing) sitting on the sides of roads and in different places
24:37 <Ampera> and I've always called them bird berries and I never knew why
25:02 <Ampera> My guess is they're bittersweet nightshade, but I've found out a very similar looking plant exists, perhaps I saw it when I was in Europe, called bird berries
25:03 <T3sl4> oh, nightshade?
25:09 <Ysjoelfir> rusty, yes, always! :D
25:17 <Ampera> https://en.wikipedia.org/wiki/Psychotria_capensis
25:18 <EEVBot> [Title] - Psychotria capensis - Wikipedia
25:29 <Ampera> the berries look very similar to bittersweet nightshade
25:54 <Lemon> hmmm mine wasnt outputing something like that
26:04 <Lemon> maybe its keysight IO thats making issues
26:35 <T3sl4> of course it supports many formats, that happens to be monochrome BMP
27:13 <Ampera> hrm
27:19 <Ampera> it does look like bittersweet nightshade is also native to Europe...
27:21 <T3sl4> Ampera: i've always known it as the plant of that sort, with obvious nightshade characteristics (familiar purple and yellow flower, prominent calyx around fruit, potatolike leaves)
27:45 <Ampera> known the term bird berries?
28:19 <T3sl4> not sure we use that term here
28:36 <Ampera> I'm just wondering why /I/ use that term
29:20 <Ampera> and stumbling across that south african plant that is named bird berry, I wonder if the terms somehow crossed over
30:10 <T3sl4> i mean, it's a pretty trivial name
35:53 <Lemon> hoooo I just read its possible to hack the ths710a into a 720p :o
36:18 <Lemon> that would be super neat ! from 60 Mhz 250ms/s to 100Mhz and 500ms/s
36:23 * Ampera squeezes the Lemon 
36:29 <Ampera> how are you doing Lemon
36:45 <Lemon> hoooo tired af and you ?
37:01 * Ampera sneezes
37:06 <Ampera> that's how
38:19 <Lemon> on top of that the P version does power analyzing
39:37 <Lemon> im a bit sad I sold my siglent arb gen, because I could have used it to calibrate it
40:01 <Lemon> but the hack, a new battery and later a re-cal it would make a super nice device
40:06 <Lemon> right now its in a closet...

51:39 <Lemon> so I dug the ths710a, and a power adapter
52:02 <Lemon> works perfectly, I tried with the isolated probe and the compensation thingie works fine !
52:08 <Lemon> theres also no dc offset
52:19 <Lemon> I think I will order a battery, and do the mod
52:31 <Lemon> in the memory of my dear father :>
52:40 <Lemon> if only he knew you could do that...
53:04 <T3sl4> aw
55:13 <Lemon> I know he got it from the last place he worked as a gift when he left
55:23 <rust_collector> do you need to do any physical changes to it?
55:25 <T3sl4> hm, this vax ahot hits different. i'm starting to get the muscle soreness and malaise of an immune reaction, but i have no symptoms
55:32 <T3sl4> which is after all the point :)
55:38 <Ampera> second one?
55:42 <T3sl4> ye
55:45 <Ampera> which variety
55:47 <Ampera> pfizer?
55:49 <Lemon> yes rust_collector but its not a lot, gladly. just 3 smd resistors to remove from what I read !
55:55 * T3sl4 sneezes moderna spike proteins at Ampera
56:02 <Ampera> ah
56:07 <Ampera> my mom had the moderna and had it worse than I did
56:23 <Ampera> she said she had searing body pains worse than she's ever experienced before
56:28 <Lemon> my mother recently learnt she got the virus, one year ago, when it began
56:28 <T3sl4> i was expecting to be much more out of it today, it's pretty mild so far
56:45 <Lemon> we thought she had it as she was quite sick, but nothing more than a regular big flu
56:59 <Lemon> what a chance I didnt get it, or maybe I did but im asymptomatic
57:32 <Ampera> Before getting the vaccine (now it'd probably be useless as I'd have antibodies for the vaccine) I considered seeking out an antibody test
57:52 <Ampera> it'd just be out of curiosity, which is why I didn't
57:53 <T3sl4> a friend got pfizer, and one hell of a migraine... :/
58:05 <Ampera> my main symptom was stomach pains
58:19 <Ampera> and an inflamed left arm, though my first shot was worse on the left arm count
58:35 <Ampera> it was the point of bad to where I decided to take something for it
58:46 <Ampera> aspirin, paracetamol, and diphenhydramine
59:03 <Ampera> yes I know why that's probably not a great thing to take when you want an immune reaction, but I don't care
59:10 <T3sl4> i didn't know you were on your period ;)
59:20 <Ampera> that'd be one hell of a period
59:51 <T3sl4> i mean, periods are often hell
59:55 <T3sl4> so, yes
00:00 <Ampera> I wouldn't know, so I couldn't say.
00:38 <rust_collector> they can be pretty horrible, for some people
02:36 <T3sl4> get some womenfriends, they'll be glad to illustrate what they go through :P
03:34 <Ampera> None of the women I have ever known have ever felt the need to tell me about their periods.
04:03 <Ampera> and I honestly haven't felt it was any of my business to ask them either
05:52 <EEVBot> [Twitter] - eevblog - Some good advice from Dilbert https://t.co/MPodRAIgVf
06:00 <T3sl4> i know one or two with endometriosis. just reading the anatomical description of that makes me hurt. i can't imagine having to endure that
07:49 <K> hrm, does not seem fun indeed
08:20 <rust_collector> that is a thing here now, there is no place that specialize in it here, and someone found out that there are 7 places in sweden, so why don't we have any? And getting diagnosed tends to take years...
09:15 <Ysjoelfir> I wonder if I should get two HP LP2065 20 inch 4:3 LCDs for the lab..... right now I only have one small 24" touchscreen which I mainly use for the soldering microscope, that one is also mounted in an inconvenient place for PC work. hm.
09:35 <Ysjoelfir> I found 2 of them for 60€ for both.
09:36 <Ampera> I've never had a touchscreen monitor
09:44 <Ampera> touchscreen tablets/laptops sure
09:58 <Ampera> I think it'd be fine so long as it was glass, and easy to clean
10:05 <Ampera> it could be quite useful in a kitchen settings
10:28 <Ysjoelfir> I wanted the touch as my soldering microscope has a mouse input. its pretty convenient to controll that by touch. other than that, I don't need that at all and usually hate touchscreens in the lab^^
14:46 <Ampera> I think the only big reservation I have about potentially getting a macbook is the lack of a touchscreen
15:25 <Ysjoelfir> I don't like apple, so that would be my reason. but thats personal preference :) Also, I think I get those two monitors.
15:51 <Ampera> For me, I work in mobile software, so I kinda have to get used to apple one of these days
16:03 <Ampera> plus I really kinda want some of their sci-fi ARM tech
16:14 <Ysjoelfir> you got a very valid point there (the work part)
16:15 <Ampera> maybe with a copy of Parallels, since it seems like an actually competent hypervisor
16:28 <Ysjoelfir> the space tech part I get as well, but it wouldn't be a reson for me
16:36 <Ampera> if it could dual boot with Linux proper, I'd get it as soon as it came out
16:48 <Ampera> it wouldn't even be a competition
17:50 <Ysjoelfir> maybe I should get that as well for the lab.. https://www.ebay.de/itm/353051305063?hash=item52337f6467:g:DIUAAOSwEcpai~95

17:52 <EEVBot> [Title] - EditShare Server 2GB RAM 26x 500GB HDD Broadcasting Server | eBay
18:18 <rust_collector> yes, I don't think so
18:41 <Ysjoelfir> no, I don't need it at all. I just stumbled over it in the monitor sellers shop
18:54 <Ampera> who fucking made that server
18:57 <Ysjoelfir> my shitty NAS has 12 HDDs and thats more than enough
19:02 <Ampera> I've never seen a pure SATA backplane like that
19:05 <Ampera> SAS exists for a reason....
19:31 <Ampera> what cards even are those...
20:05 <Ysjoelfir> heh, Ampera we had a simmilar thing "back than" when I worked for the transport company. I probably even have the SATA controllers somewhere. they were pretty shite, 12 channels per card but only a maximum of 2TB per controller
20:26 <Ampera> That's a bizarre limitation
20:46 <Ampera> I could maybe see 2TB per drive, as an LBA limitation /maybe/
20:50 <Ampera> but 2TB per controller?
21:12 <Ysjoelfir> thats probably because they don't offer any raid, only JBOD IIRC? could that be?
21:45 <Ampera> oh if it was a RAID card...
21:57 <Ampera> (JBOD is technically RAID, just without the RAID)
22:11 <Ampera> then I could see it having some sort of addressing limitation imposed by the array
22:31 <Ampera> still, I don't know why anyone would do this when SAS is a thing that exists
22:50 <Ysjoelfir> cost, probably. back than SAS was freakishly expensive
23:07 <Ysjoelfir> at least that was the reason I was told when I asked the same question when we dismantled those old servers
24:14 <Ampera> I need to redo my desktop, I'm debating switching distros to Debian at some point
24:37 <Ampera> It's hard to reason since Arch works fine, but there's a lot of stuff I need to change around, and I might as well learn a new distro while I'm at it
24:44 <Ampera> it'd be useful for when I need to do Linux servers one day
25:20 <rust_collector> I ended up putting regular debian on the core duo box. it runs much better than it should, lol
25:55 <Ampera> core duo was such a weird fucking chip
26:10 <rust_collector> ok
27:01 <rust_collector> i sort of want to put a core2duo in it, but I also like the quirkiness of leaving it alone
27:14 <Ysjoelfir> I still have a Q6600 somewhere....
27:32 <rust_collector> I do have a core2quad somewhere
28:03 <K> git push
28:05 <K> asfoaisdjfo
28:16 <rust_collector> yes
28:19 <Ysjoelfir> probably
29:30 <Ampera> you're pushy today
29:30 <Lemon> hmmm so they managed to turn the 710a (60Mhz, 250Ms/s) into a 720p (100Mhz, 500Ms/s base, with power analysis) and also got the 1Gs/s sampling rate from the 730
29:46 <Lemon> the hard part is to flash the new firmware
29:57 <rust_collector> is it?
30:02 <Lemon> but to change the device to upper model its just a few resistors to remove
30:08 <Lemon> yeah you need to desolder a chip, flash it etc
30:15 <Lemon> and its no through hole stuff
30:19 <Lemon> I never did that
30:35 <rust_collector> do you have to desolder all of it?
30:38 <Lemon> but I thought, maybe I could ask a peep on the forum that did it to do it for me
30:58 <Lemon> yes it seems, and use a programmer + adapter that I dont have, and its decently expensive
31:02 <Lemon> welll, like 100 euros for both
32:00 <Lemon> so maybe I could ask a member to do it for me, then I could get a second probe, a new battery
32:02 <Lemon> and bam !
32:16 <rust_collector> POOF!
33:15 <rust_collector> ask mr head about that, he likes his flashing things
33:33 <Lemon> if its really possible to have the sampling rate of the 730a, but not the 200Mhz bandwith (im fine with 100) that would be insane
33:52 <rust_collector> sounds sane enough
33:54 <Lemon> 1Gs/s and 100Mhz, + power analysis and harmonic analysis tool is a super big upgrade
34:07 <Lemon> from 60Mhz/250ms/s and none of those analyzis tools
34:35 <Lemon> 38 euros for a new battery is ok, it was 120+ a year ago, hence why I didnt replace it
37:01 <Lemon> and I recently found the probe, too
37:14 <Lemon> and a second one but tip is broken
37:24 <Lemon> my father was kinda rough with his stuff, sadly
38:17 <Lemon> I didnt check for the rs232 cable tho lets see
46:27 <rust_collector> are the probes ok at 300ghz?
02:41 <Lemon> they are for 200Mhz afaik
03:12 <Lemon> tbh I'd be fine with stock bandwith, sampling rate too, but its always nice to upgrade something like that
03:28 <Lemon> the power/harmonic analysis tool is really cool tho

04:16 <EEVBot> [Title] - Meanwell MW switching power supply S-250-24 24V 10A 250W | eBay
07:39 <Lemon> seems the answer is yes
08:01 <Lemon> you could make a hell of a power supply with those, I wonder how doable is it to reduce ripple tho
12:23 <hsn> Lemon, i think u 've to put diodes in across each rail when u connect them in series .. but T3sl4 can help more of why .. im not sure
12:45 <Lemon> yes I just read that, thats true !
12:46 <T3sl4> if they're isolated, doesn't really matter
13:05 <T3sl4> but yes, antiparallel diodes can help prevent reversal
13:06 <Lemon> they state 150mv p-p of noise, could this be reduced ?
13:37 <T3sl4> most PSUs will have an output rectifier in the same place, but i suppose one on the outside is easy insurance in case it doesn't like that
13:38 <Lemon> I thought about a variable power supply with those modules
13:55 <T3sl4> Lemon: of course it can, how much do you want to filter or postreg?
13:58 <Lemon> and I wonder if its doable to reduce the ripple to a maximum
14:11 <Lemon> well that is the big question, what is possible withing a reasonnable budget ? :>
14:28 <T3sl4> my measure of "reasonable" might not match yours
14:59 <hsn> T3sl4, if they are in parallel .. isnt that problem ?
15:13 <T3sl4> what are
15:25 <hsn> they will fight to output some voltage .. one will output 23.8v another 24.2v ?
15:37 <hsn> and wires have very low resistance ?
15:38 <T3sl4> PSUs in parallel? yes
15:56 <Lemon> lets say I want to reduce it to 10mv/p-p, is it reasonnable ?
16:19 <T3sl4> i'd have to know what frequencies, but if it's all high frequency that should be pretty easy yes
16:25 <hsn> i think lemon asked about both parallel and series ..

17:13 <Lemon> well it depends, lets say it could be interesting to build a highish voltage/power supply with those, add a circuit to make it variable, add protections etc
17:17 <Lemon> current limiting and so on
17:28 <Lemon> and reduce the ripple, so it could be used in the lab
17:28 <T3sl4> if the supplies have current limiting, then the highest output one will saturate first, and then output voltage falls slightly and the next supply starts delivering current, and so on
17:55 <T3sl4> which heavily loads the highest voltage supplies, maybe not ideal for efficiency, but shouldn't be fatal
18:36 <T3sl4> to get sharing in parallel you really need series resistors (that worsen regulation overall) or a master-slave architecture instead of independent supplies
19:07 <hsn> T3sl4, or two bulky diodes before parraleling them ?
19:29 <T3sl4> diodes dont drop much voltage, and the supplies likely won't care about backfeeding
