00:08:53 <K> sendmail or bust!
00:08:58 <K> (ducks)
00:09:21 <Ampera> I'll take the busts, thanks
00:10:52 <K> foiled again
00:14:02 * Ysjoelfir has.... erm.... meatballthings. Frikadellen.
00:14:23 <K> in a soup?
00:14:24 <rust_collector> meaty balls
00:14:32 <Ysjoelfir> no. stand alone, K
00:14:35 <K> oh.
00:14:44 <K> we do frikadellen soup here
00:14:46 <Ampera> why are you
00:14:55 <K> with a little bit of potato and carrot
00:15:31 <Ysjoelfir> frikadellen sopup, that sounds nice. do you have a recipe?
00:15:51 <K> uhh, not really
00:16:09 <rust_collector> broth potato and carrot, bay leaf, and balls
00:16:38 <K> https://www.delfi.lv/tasty/receptes/klasiska-frikadelu-zupa.d?id=43622647
00:16:39 <EEVBot> [Title] - Klasiskā frikadeļu zupa - DELFI
00:16:47 <K> not much to it
00:17:11 <K> in picture there is rice inside meat balls, though i do not know anyone who does it like that
00:17:25 <rust_collector> what is a gave?
00:17:35 <rust_collector> pcs?
00:18:04 <K> gave?
00:18:21 <rust_collector> oh heh. gab
00:18:22 <Ysjoelfir> damn, accidentally closed the IRC client. what did I miss?
00:18:53 <K> "gabals" is "piece"
00:18:57 <rust_collector> ah
00:19:11 <K> shortened to gab.

00:19:42 <K> >> K | in picture there is rice inside meat balls, though i do not know anyone who does it like that
00:19:44 <Ysjoelfir> uuuuh!
00:19:58 <Ysjoelfir> I will do a soup tomorrow, maybe I let myself be inspired by that
00:20:05 <rust_collector> I was lazy and pushed the translate button, and it said "1 gave blahblah"
00:20:08 <rust_collector> oh well
00:20:31 <K> usually the meatballs are about 20mm dia, not more
00:21:00 <K> thoug i am not a cook
00:22:29 <Ysjoelfir> damn that sounds good. I will definitely get some inspiration of that
00:23:12 <T3sl4> have seen rice in meatballs before, i think any kind of starch is not unwelcome
00:23:21 <T3sl4> bread crumbs being a more traditional ingredient
00:23:32 * Ampera pours laundry starch all over T3sl4
00:23:46 * T3sl4 potato starches Ampera
00:23:55 <Ysjoelfir> yep, we do breadcrumbs in ours
00:23:55 <Ampera> you callin me a potato?
00:24:43 <T3sl4> yes
00:24:56 <Ampera> why you low down bulbous root
00:25:03 <Ysjoelfir> oy blin! potjeto!
00:25:24 <T3sl4> you too, egg?
00:25:45 <T3sl4> Ampera: tubermensch
00:26:25 <K> white bread is used for cutlets, and that is quite similar to frikadellen
00:29:40 <Ysjoelfir> K, let me guess... Ola is oil?
00:29:48 <Ysjoelfir> it didn't manage to translate that
00:34:35 <rust_collector> egg
00:35:14 <rust_collector> only thing that is missing, I think
00:39:36 <K> Ola is Egg
00:40:48 Join: Nero ([email protected]) to #EEVblog
00:41:13 <Nero> T3sl4, I need your wisdom
00:41:21 <T3sl4> $100/hr
00:41:25 <Ysjoelfir> well, yes, one piece of oil would indeed be strange
00:41:47 <Ysjoelfir> uh, Nero gets a discount from T3sl4!
00:42:02 <T3sl4> oh wait i replied way too soon, prompt service like this is at least 200

00:42:10 <EEVBot> [Title] - Youtube: D̤e̤p̤e̤c̤h̤e̤ ̤M̤o̤d̤e̤ ̤M̤ṳs̤i̤c̤ ̤F̤o̤r̤ ̤T̤h̤e̤ ̤m̤a̤s̤s̤e̤s̤
00:43:06 <Nero> T3sl4, damn
00:43:13 <Nero> I guess I´ll keep it short then
00:43:27 <Nero> I need to make a bias board that has supplies controlled by a dac
00:43:30 <Nero> I want a simple solution
00:43:39 <Ampera> simplicity is 300/hr
00:43:40 <rust_collector> make it a yes or no question....
00:44:09 <Nero> should I just use a power-opamp in unity-gain feedback to buffer the output of the DAC, or should I just use the DAC to drive the ´set´ pin of a variable LDO
00:44:39 <T3sl4> uhh... how accurate does it need to be
00:44:41 <Nero> I know nothing of this kind of DC wizzardry
00:44:47 <Nero> not super-duper accurate really
00:44:58 <Nero> <1% would be nice but not required
00:45:08 <T3sl4> might even be better to use a crappy power buffer with a prec amp around it, and remote sense terminals or something too
00:45:13 <T3sl4> but that should be easy enough either way
00:46:24 <Nero> advantage of the LDO seems to be that they are more stable w.r.t. load capacitance, but they have a minimum output current, and the don regulate down to say 300 mV
00:46:49 <Nero> how is everyone doing btw
00:46:50 <K> dac alone does not have enough current?
00:47:05 <Nero> K, not really - itś a 16 channel dac and I have some 200 mA supplies
00:47:09 <K> ah.
00:47:19 * T3sl4 hugs Nero
00:47:37 <Nero> Iĺl use the DAC direct for my bias voltages (which are high-impedance anyways) (but I might buffer them for protection reasons)
00:47:39 <rust_collector> everyone is doing!
00:47:49 <T3sl4> steve30: https://i.imgur.com/joWInnM.jpg
00:48:16 <K> haha, clearly not amused
00:48:23 <Ysjoelfir> lol
00:48:55 <Ysjoelfir> also, mrs. spouse just tortured me with that, being played on the amazon echo on full blast: https://www.youtube.com/watch?v=7fk6mku5qfA
00:48:56 <EEVBot> [Title] - Youtube: The Chicken Wing Beat
00:50:26 <T3sl4> Nero: so, you'll need a negative supply to use the LDOs near 0V, which is doable but maybe annoying, and if it's a one off testing thing cost doesn't matter?
00:50:47 <T3sl4> might even get dual power amps, to save on space a bit?
00:51:08 <Nero> T3sl4, I was thinking about a RIRO opamp? and indeed, the opamp Iḿ getting is dual 400mA output (thermal management will be a mess though)
00:51:35 <T3sl4> SONs are good for that
00:51:48 <Nero> considering we are spending >500 bucks per PCB on the PCB itself
00:51:49 <rust_collector> Ysjoelfir why not nyan cat in the morning?
00:51:52 <Ysjoelfir> Nero, when you are done discussing... tell us, where have you been, what happened to your house and so on :)
00:52:00 <Nero> I don worry too much about the individual opamp :p
00:52:02 <Ysjoelfir> rust_collector, I did that to her. she was pissed. much.
00:52:29 <rust_collector> good, so she is just returning the favor...ok
00:52:29 <Nero> I will Ysjoelfir
00:54:10 <Ysjoelfir> .o\
00:54:12 <Ysjoelfir> erm
00:54:16 <Ysjoelfir> \o./
00:54:18 <Ysjoelfir> dammit
00:54:23 <Ysjoelfir> \o/
00:54:35 * T3sl4 dusts off the dirt from Ysjoelfir's shoulders
00:54:56 <Ysjoelfir> thanks, now I feel better
00:57:27 <electrohead> \o/
00:58:00 <Nero> Ysjoelfir, we finally started working on my house
00:58:10 <Nero> already ran into water issues, one of the walls is soaking wet
00:58:13 <Ysjoelfir> nice :)
00:58:17 <Ysjoelfir> thats not so nice
00:58:37 <rust_collector> you what?
00:59:01 <Nero> I also finished my first tapeout a few weeks atgo
00:59:04 <Nero> was hecktic at the end
00:59:26 <Nero> and so now I designing the test-PCB and biasing boards
01:01:03 * steve30 meows at T3sl4
01:01:21 <Nero> but if all goes well and the chips work Iĺl have a high-speed transmitter by the end of august to test
01:01:42 <T3sl4> yey!
01:01:55 <Ysjoelfir> nice, that sounds successfull :)
01:02:09 <Nero> with a meager 100-150 gbit throughput
01:02:56 <Nero> but man the PA chain was an absolute nightmare
01:03:05 <Nero> hard to design an amp when you have 3 dB max gain at your frequency
01:04:33 <Ysjoelfir> but you managed to do it
01:04:51 <Nero> yes, to some extent lol
01:05:22 <Nero> considering I get about 4 mW output power for 200+mW power conssumption, it´s not the most efficient thing ever though
01:06:27 <Ysjoelfir> 2% efficiency, good enough!
01:06:45 <electrohead> o.O
01:06:46 <electrohead> lol
01:07:45 <Nero> but when you do the math on expected energy/bit transmitted we aren´t abbysmal so itĺl be fine
01:09:22 Join: Kuschelpony ([email protected]) to #EEVblog
01:09:40 <Ysjoelfir> well, I assume said math is all but trivial :P
01:09:58 <Nero> well, that is kinda easy
01:10:12 <Nero> you look at bit/s and watt/second and you get watt/bit
01:10:21 <Nero> and watt/second happens to be power
01:10:52 <Ysjoelfir> oh. right, thats indeed not hard

01:16:39 <EEVBot> [Title] - Youtube: Owls Hate Simon Cowel : animated music video : MrWeebl
01:16:59 <Kuschelpony> hmm, i might have mnissed the beginning of this discussion, but what physical meaning does watt/second have for you?
01:17:02 * T3sl4 badgers rust_collector
01:17:58 <Nero> Kuschelpony, isn´t power energy/time?
01:18:00 <Kuschelpony> the only place i know an unit of thisdimension is to describe the rate how fast an power station can ramp up or down fro thermal limits, but in 99,9% other cases it leads me to think someone has mixed up units
01:18:18 <Kuschelpony> yes, but watt is already "poer" and not energy
01:18:19 <Nero> one watt is one joule every second, no?
01:18:22 <T3sl4> think he meant watt.sec == joule
01:18:22 <Kuschelpony> right
01:18:26 <Nero> oh sorry
01:18:29 <Nero> I meant joule
01:18:33 <Nero> yeah you are right
01:19:08 <Kuschelpony> i wonder why you divide watt/second because watt is already joule/secojnd and therefor you calculate joule/second^2
01:19:12 <Kuschelpony> ok
01:19:28 <Kuschelpony> just home from 12 hours at work and thats the frist thing that hit my brain :)
01:19:46 <Nero> we usually compare links on either raw throughput, or on energy/transmitted bit
01:20:01 <Nero> something on the order of magnitude of 1 pJ per bit is common
01:20:29 * T3sl4 hugs Kuschelpony
01:21:49 <Nero> and in my case, my link should be about 3 pJ/bit, which is not groundbreaking but aint horrible either
01:22:24 <T3sl4> room for improvement
01:23:43 <Nero> T3sl4, I prefer to improve on the gbit/second part
01:23:55 <Nero> leave the joule/bit to industry
01:23:59 <T3sl4> sure
01:34:14 <Lemon> so I got my pack of those wire jumpers that stays flat on the breadboard
01:34:28 <Lemon> its surely super nice and tidy now, but I realize that my breadboards are shit
01:34:45 <Lemon> they are hyper stiff, its not the first time I noticed it ofc but two of the 5 I have are really nice
01:34:57 * hsn squeeze a lemon
01:34:59 <Lemon> I guess they were my fathers, but knowing him he didnt buy a branded one
01:34:59 <Ysjoelfir> Lemon! say hi to Nero!
01:35:23 <Lemon> bonjour Nero !
01:35:27 <hsn> hii to Nero hi to Ysjoelfir
01:35:28 <Nero> Allo!
01:35:36 <hsn> can you hear me ?
01:36:02 <Nero> what do you mean hear me
01:36:43 <rust_collector> doesn't matter, just say no
01:37:34 <Ysjoelfir> also, it finally arrived, yay! :D https://drive.google.com/file/d/17Jg8rQjY8fGLX1sPUMDzGGM0X6Qhc0sh/view?usp=sharing

01:37:41 <rust_collector> if you start talking to hsn, he will try to sell you some camels or whatever they have there. locusts maybe
01:37:58 <hsn> yes
01:38:47 <hsn> nero in arab country .. "allo" used as first word in phone call .. or "when u cant hear the other person in a phone call"
01:39:04 <hsn> alloooooo alooooo can u hear me ?
01:39:06 <hsn> like this
01:40:22 <rust_collector> hi hsn !!!
01:40:40 <hsn> hi rust the undust
01:41:10 <Nero> you did a course from Fedevel? are you happy about it? I did some consulting (Read, back-and-forth linked in messages) about some impedance stuff with Robert a year or so back
01:41:42 <hsn> Ysjoelfir, did ^
01:41:54 <Lemon> allo is also the same in france :>
01:41:54 <Nero> I´m thinking about suggesting a basic course for newbies at my researchgroup
01:42:36 <Nero> lemon, you french?
01:42:44 <Lemon> Ysjoelfir ggwp ! you can now make leds blink in an advanced way I guess ? :>
01:42:51 <Lemon> yes I am :<
01:43:44 <Ysjoelfir> Nero, yep, did actually do 3 courses there already, though this is the first one that I got a certificate for (didn't bother with the other two). And I enjoyed it a lot. The newer courses are realy good, though the older one I took from him was soooooooooo slow.... ok, robert is a very slow speaker, but even with double playback speed it was boring as hell. but the newer ones.... great with 1.75x speed.
01:44:15 <Ysjoelfir> and I just love the way he pronounces Capacitor
01:44:41 <Nero> kaPAcitoor
01:44:51 <K> kapaaacitoor
01:44:56 <Ysjoelfir> yep xD
01:45:13 <Nero> Lemon, do you do this thing where you say ´capa´ instead of cap? :p
01:45:44 <Lemon> yes, I'll admit it x)
01:45:57 <Nero> I had a 2-day course from ST on their bicmos technology
01:45:58 <K> kondensātors here
01:46:01 <Nero> it drove me nuts :p
01:46:13 <Ysjoelfir> K - Kondensatoren in german :P
01:46:28 <K> the proper way yes
01:46:54 <rust_collector> yes
01:47:01 <Nero> in dutch it´be condensator, but me and my colleagues tend to use the english shorthand ´cap´ when refering to them
01:47:40 <Ysjoelfir> in german we use the abbreviations "Elko" for electrolytics and "kerko" for... everythign non electrolytic, no matter if its realy ceramic or a foil
01:47:58 <Nero> oh. Elco is something we say to
01:49:35 <hsn> Ysjoelfir, he just made a video of his experience with pcba using jlcpcb ..
01:49:54 <Ysjoelfir> uh, I should watch that. link?
01:50:05 <hsn> in this first minute i loled .. he was like --> yeah i know u thinking why 25 minutes for such info

01:50:55 <hsn> i didnt feel there is anything special just documenting his experience ..
01:51:27 <Ysjoelfir> I watch it and tell you the result :P
01:52:36 <Nero> I only use swiss PCBs
01:52:38 <Nero> best PCBs
01:52:55 <Ysjoelfir> your projects tend to be a bit more complicated though :P
01:53:14 <Nero> what? naaahh
01:53:20 <Nero> just like, 160um pitch devices :p
01:54:36 <hsn> i use pcbway .. with fr4 material .. no THZ speeds
01:54:46 <hsn> or MHZ speeds :D
01:54:56 <hsn> wait .. the oscillator only ..
01:55:11 <Ysjoelfir> same, I use either PCBway or german companies, mostly Wuerth
01:55:32 <Nero> PCB I´m designing with now has 60 um diameter vias and 55 um width tracks ;d
01:56:42 <Ysjoelfir> thats giant! next time I expect 7nm tracks.
01:57:02 <Nero> that is on chip... 50 nm tracks and stuff :p
01:57:41 <Ysjoelfir> :P
01:57:46 <hsn> last time i selected some pcb that has high glass transision temperutre .. because that way my company pays more

02:17:01 <Nero> yeah it should be fine
02:17:24 <hsn> comprimise the A0 and A1 .. :D
02:19:18 <Nero> also notice the order of DAC channels is all whacky
02:19:44 <K> it expensive though

02:48:25 <hsn> K do u do rtos coding?
02:48:46 <K> not really hsn
02:49:06 <K> i do quite a lot of general coding though
02:49:39 <hsn> You work as embedded software engineer right?
02:50:34 <DHess_US> I used to do RTOS but at the bare metal level. That was fun.
02:51:32 <hsn> DHess_US: u mean writing ur own context schuduler?
02:52:04 <hsn> And kernel intercommunication other stuff?
02:59:00 <DHess_US> I never needed anything that complex, but I always wanted to write a minimum optimized version of those for small hardware.
02:59:48 <DHess_US> The scheduling I did was static and defined at compile time, with no heap. The step up from what I did would include a heap designed for real time operation which is a major problem.
03:00:26 <K> i have several hats, hsn
03:00:27 <DHess_US> A heap can cause a lot of problems in a real time system, or any system which must be reliable.
03:01:07 <DHess_US> But the alternatives to a heap aren't any better unless the alternative is static allocations.
03:02:06 <DHess_US> hsn, I don't know what kind of kernel design I would have ended up with. My experience at that level is with ancient OSes like Apple DOS.
03:06:20 <DHess_US> I'm not real happy with the AC adapter for my DE-5000. I wonder if this would be a bad idea, https://www.amazon.com/CCYC-Voltage-Converter-Wireless-Speakers/dp/B07QL2YG1V/

03:14:03 Join: Beni2 ([email protected]) to #EEVblog
03:37:37 <T3sl4> DHess_US: i think it's funny to call things like that an RToS. i got away with that on my college capstone project, just put a bunch of housekeeping routines in a timer interrupt and called it "cooperative multitasking"
03:42:40 <DHess_US> It doesn't fit the definition of cooperative multitasking though.
03:42:51 <DHess_US> The timer interrupt happily interrupts anything going on.
03:43:29 <DHess_US> The way I understand cooperative multitasking, that means tasks voluntarily release their progress to other tasks.
03:44:16 <DHess_US> I didn't use "just" the timer interrupt. The timer interrupt triggered other slower timer interrupts so there were several. So tasks could be assigned to 1ms, 10ms, etc.
03:45:42 <T3sl4> yeah exactly what i did
03:46:39 <T3sl4> i mean, it's cooperative in the sense that, as a real time system, nothing should ever take longer than its cycle, and if it does it probably piles up and crashes
03:46:51 <coppice> "the definition"? which God provided this definitive definition?
03:46:53 <DHess_US> The lack of complexity without any dynamic allocation is an advantage because there is less to fail.
03:47:10 <T3sl4> coppice: what's a god?
03:47:36 <coppice> T3sl4: some 4 legged creature who is a bit backwards
03:48:39 <T3sl4> sounds adorable
04:05:46 <hsn> DHess_US: MISRA or other safety standards discourage or prevent heap allocation
04:07:55 <coppice> The standard designed to make you MISRAble
04:07:57 <hsn> T3sl4: a beremetal functions hat are yielding .. cooperative threads .. nothing wrong with that i guess .. untill one of them has lots of functions and u need to do yield alot in middle of algorithms .. right?
04:08:21 <coppice> I don't think I've ever met a standard as annoying as MISRA
04:08:23 <hsn> coppice: specifically the mil ones
04:08:29 <T3sl4> or if it's a full moon, a weremetal function
04:08:46 <coppice> hsn: MISRA is commercial
04:08:46 <DHess_US> hsn, yes.
04:09:10 <hsn> coppice: unfortunately .. yes
04:09:30 <T3sl4> in principle, the way i did it (and probably DHess_US), assuming subsequent calls don't stack up, it'll simply interrupt the running instance, do its activities, and resume
04:09:33 <DHess_US> hsn, I can understand why, but I still would enjoy the challenge of designing and implementing a "safe" RTOS with heap support.
04:09:57 <hsn> Even tools that can check ur code like cppcheck .. offer misra complience checker if u offered the rules. . which isnt available
04:10:07 <coppice> T3sl4: if you do 100% of all processing in interrupt routines, does that qualify as cooperative multitasking?
04:10:13 <DHess_US> T3sl4, I just kept it simple with a main routine which was constantly executing and draining data from queues which were filled by the various interrupt routines.
04:10:52 <T3sl4> ironically, i can't actually do that with the AVRs i've been using (XMEGA, vs MEGA164 i think that was), because the interrupt controller watches for RETI execution
04:10:55 <DHess_US> In practice the interrupt routines only took a minor fraction of the CPU clock cycles. Contention was never a problem.
04:11:16 <T3sl4> DHess_US: yeah, that's the better way to do it, set flags in ints and round-robin or whatever through it
04:11:35 <hsn> DHess_US: the FreeRTOS has 3-4 memory schemes under names like (heap1.c ... Heap4.c) .. i never dared to open and understand them ... For me heap is malloc i never go to sbrk
04:12:06 <DHess_US> My favorites were the interrupt routines which monitored for keyboard activity and filled shadow registers with the results.
04:12:07 <T3sl4> the way i did it, there was some glitchy (obviously race conditions) behavior that i didn't quite figure out, and that was years ago so yeah what do i care :P
04:12:30 <coppice> T3sl4: RETI doesn't invalidate a 100% in interrupts design, if the main code just initialises things and waits in a tiny loop.
04:12:43 <hsn> How do i design a queue ? When i dont know how to design semaphore or mutex
04:13:05 <T3sl4> coppice: for doing overlapping interrupts, it does
04:13:27 <DHess_US> hsn, with a pair of pointers.
04:13:29 <coppice> hsn: don't design a queue. just get a ready made one from England. We have plenty
04:14:01 <T3sl4> i think the workaround would be, make a stub handler that executes RETI, possibly with faked return address so that it tail-calls the intended function, which can then be interrupted as if main()
04:14:03 <DHess_US> One pointer is controlled by main, and the other by the interrupt. If the pointers don't match, then there is data in the queue.
04:14:08 <coppice> T3sl4: Its May, and all the interrupts are nesting
04:14:55 <Lemon> I got my dear luxmeter !
04:15:12 <T3sl4> soon their APIs will be tweeting, then they fly off the stack
04:15:17 <DHess_US> I'm getting parts tomorrow from Mouser to repair two multimeters.
04:15:23 <hsn> DHess_US: thats thread safe ? For multi-threads ? .. no right?
04:15:41 <DHess_US> Refurbishing 2 DM502s, and changing the memory backup battery in my HP bench meter.
04:15:43 <T3sl4> hsn: you do it this way https://github.com/T3sl4co1l/Reverb/blob/master/bufserial.c
04:15:45 <EEVBot> [Title] - Reverb/bufserial.c at master · T3sl4co1l/Reverb · GitHub
04:15:57 <DHess_US> hsn, there are only two threads, so yes.
04:16:15 <DHess_US> The interrupt is the only thing writing to one pointer, and the other pointer is only written by main.
04:16:44 <DHess_US> Since the pointers are only updated by each, data in the queue never gets overlapped writes.
04:17:37 <DHess_US> The interrupt only updates its pointer after writing data to the queue. And main only accepts that data after it detects that the interrupt pointer does not match the main pointer.
04:17:44 <T3sl4> i chose not to use atomic.h in that code, as disabling the interrupt has the same effect. the advantage is, other unrelated interrupts can run -- on the assumption that they do not interact with these objects
04:18:12 <DHess_US> Obviously there is an assumption there that pointer updates are atomic.
04:18:43 <T3sl4> if that's a hazard, then using ATOMIC_BLOCK is a good idea
04:18:48 <hsn> T3sl4: why u do register define in side buf.h not buf.c .. is it being accessed in multi c?
04:18:57 <DHess_US> https://www.lightningmaps.org/#m=oss;t=3;s=0;o=0;b=0.00;ts=0;z=10;y=38.6684;x=-90.3509;d=2;dl=2;dc=0;
04:18:58 <EEVBot> [Title] - Real Time Lightning Map :: LightningMaps.org
04:19:46 <T3sl4> DHess_US: yeah, and that requires some platform dependence, like on the AVR, pointers are 2 x 8-bit words so cannot be accessed atomically in a single op, and ATOMIC_BLOCK is required
04:20:00 <T3sl4> on an ARM, a 32-bit word should always be atomic, i think?
04:20:18 <T3sl4> of course you can always use ATOMIC when you're supposed to :)
04:20:21 <DHess_US> It should be
04:20:29 <T3sl4> it's just, you might not NEED to, on a particular platform
04:20:48 <hsn> That only applies to pointer?
04:20:49 <DHess_US> Or keep your queues short enough that a single word is used for addressing
04:21:31 <T3sl4> hsn: i probably don't organize my headers as well as i should. or i divide them into private and public headers, so i'm not spamming the .c with #defines while keeping them local
04:22:08 <hsn> I see ..
04:22:11 <T3sl4> yeah, like, pointers on AVR might not be atomic, but the serRxBufferStart and Tx are guaranteed atomic, because they're 1 byte
04:22:58 <T3sl4> so like, bool serRxBufferEmpty() { return serRxBufferStart == serRxBufferEnd; } doesn't technically need ATOMIC
04:23:11 <DHess_US> Also the interrupt can see if the queue is full by checking the pointers, since main only updates its pointer after it digests data from the queue.
04:24:12 <hsn> Do u do doxygen stuff T3sl4 ? I see ur functions are described with that format .. or thats just for the text editor coloring?
04:24:25 <T3sl4> yes
04:24:41 <T3sl4> to that last part
04:25:03 <T3sl4> i got in the habit of /** */ ever since i learned java, it also works well with codeblocks
04:25:50 <T3sl4> i'm not sure offhand if it will parse a regular block comment as a function description, that might be required?
04:27:58 <hsn> Doxygen u mean?
04:28:32 <Lemon> https://www.mainsfrequency.com/ just discovered that, thats interesting
04:28:33 <EEVBot> [Title] - Online-measurement of the mains frequency
04:28:41 <Lemon> probably comon knowledge :>
04:31:20 <Ysjoelfir> I have a nice analog mains frequency meter in my lab. I remember how you admired it :P
04:31:53 <Ysjoelfir> a vibrating reed frequency meter its called in english afaik
04:32:29 <Ysjoelfir> painted with nice radium paint
04:33:10 <Kuschelpony> oh, i never heard from a zungenfrequenzmesser in radium paint, that must be quite a specialised application
04:33:28 <Kuschelpony> usually there is electric light available when it makes sense to read the frequency
04:33:42 <DHess_US> I've got something almost as good.
04:34:56 <Ysjoelfir> Kuschelpony I took a pic for you. you don't open google drive, do you?

04:38:23 <Ysjoelfir> https://snipboard.io/NKGS7Q.jpg here, for you on not-drive :) I got it together with some (as well radium painted) analog meters of various style, mostly british ones. Two of them had Antenna current (a few mA) and antenna Voltage (several kV), so I ASSUME they were from some kind of broadcast station
04:38:49 <Ysjoelfir> thats cute DHess_US :D
04:39:39 <DHess_US> Right next to my pile of 3.5" MO disks and SCSI hard drives.
04:40:28 <Kuschelpony> really interesting
04:40:57 <Kuschelpony> hmm, unusual values, must have been an very short electric antenna
04:41:23 <T3sl4> DHess_US: years ago, i was in a place where a coworker had one of those on his desk
04:41:23 <Kuschelpony> my frequency meter is a boring quadratic of the 70s one
04:41:55 * T3sl4 licks all of Ysjoelfir's dials
04:42:57 <Ysjoelfir> lol T3sl4 :P
04:43:46 <Kuschelpony> hmm, maybe, if i modifiy some lov voltage meter to have an very expanded mains voltage scale, this might make an interesting decoration piece to watch over the day
04:43:59 <Ysjoelfir> Kuschelpony, yeah, I would love to know where those were from, but the seller I got them from didn't know anything, he didn't even know what the stuff was he sold. those vibrating frequency meters are usually pretty darn expensive, but I got that one for close to nothing...
04:45:19 <Kuschelpony> oh
04:45:40 <Kuschelpony> well i saved mine from junking, but that was under special circumstances
04:45:59 <Kuschelpony> still trying to understand where yours could have been used for
04:46:34 <Ysjoelfir> If you get some Ideas I would love to hear them.
04:49:12 <Kuschelpony> sure

16:34:37 <rust_collector> hmm, it says "and is JEITA compliant." if you say that in norwegish, jeita means goat. I an not sure about this
16:34:52 <Ysjoelfir> lol :D
16:35:10 <rust_collector> also and means duck, and is is ice, and ...
16:35:30 <Ysjoelfir> wait. so... if I switch i and n in that word.... :D

16:53:57 <Ysjoelfir> i have no idea, but its going to be 30+ degrees the next days
16:54:17 <rust_collector> oh, so not like the usual 800
16:59:01 <Ysjoelfir> no, but close
16:59:23 <Lord_of_nothing_> Good morning boys and girls.
16:59:50 <rust_collector> evening person
17:03:35 <rust_collector> today, I am happy that I do not build bridges, or other tall things
17:04:39 <Ysjoelfir> why is thawt?
17:04:56 <rust_collector> they are tall, and i don't like high up places
17:05:18 <Ysjoelfir> ah. well thats a valid argument
17:22:36 <rust_collector> I am not this guy: https://youtu.be/5ekZiLX5FVg?t=328

17:25:50 <Ysjoelfir> and the one after that. wth? :D
17:26:43 <Ysjoelfir> oh god, all those car transporters... WTH don't they tie the cars down??
17:28:09 <Ysjoelfir> lol, the crane at ~9 min...
17:37:14 <rust_collector> there was 2 guys at work, that figured they would have a race, but as both trucks are limited to something, you know how that works. anyway, there was a car transporter coming the other way, and he jumped on the brakes, and this nice new bmw police car was launched off the top, and landed upside down in the middle of the road.... I dunno what happened there, but someone was upset about it
17:40:36 <Ysjoelfir> lol? :D
17:41:05 <hsn> rust_collector, ppl are dying and u talk about truck races
17:41:07 <K> hello avocados
17:41:15 <hsn> hello kewis
17:41:32 <rust_collector> hsn people die all the time, but they also make new people every day
17:41:47 <hsn> me no new ppl :(
17:47:24 * Ysjoelfir polishes hsn up
17:47:27 <Ysjoelfir> there, good as new
17:47:46 <hsn> no that wont fix me .. i mean me no new baby
17:47:56 <hsn> i wanna child
17:48:35 <rust_collector> can't you find a slightly used one? there are so many of them around
17:49:52 <Ysjoelfir> well, I am working on that for five years now, still didn't work. maybe I can borrow one from rusty?
17:50:33 <rust_collector> sure, take as many as you can carry
17:50:46 <rust_collector> or, I mean, as many as you can find
17:51:21 <Ysjoelfir> :P

17:52:37 <Ysjoelfir> so... I go and grab my new light-drugs from the pharmacy. brb
17:53:19 <K> light-drugs?
17:53:50 <rust_collector> he will see the light
17:56:57 <DogWomble> i can see clearly now my brain has gone?
17:57:43 <Ysjoelfir> better call it drugs lite? :P I just wanted to indicate that they aren't as strong as the normal medication you would get for ADHD, which is basically speed with a more fancy name.
17:59:30 <rust_collector> low fat and no sugar drugs
18:03:58 <steve30> I've had a canon camcorder on my desk in pieces for a couple of days. I *think* i finally fixed it
18:05:16 <rust_collector> the healing bench has worked?
18:06:26 <steve30> contact cleaner and sellotape actually :)
18:06:36 <rust_collector> hmm, do you need a canon cb-2lse charger?
18:06:56 <rust_collector> I have no idea where it comes from, but it is here
18:07:45 <steve30> i don't have anything that would fit that
18:07:55 <rust_collector> same here, lol
18:19:44 <steve30> these flat flex connectors do seem to get dirty when you unplug/replug them umpteen times

19:19:49 <Ysjoelfir> urglmurgl?
19:20:17 <rust_collector> oh, you tried your stuff already?
19:21:40 <Ysjoelfir> Yes. First dose of 25mg Atomoxetin is in my humble self. I don't expect any (positive) responses yet, as it supposedly needs some weeks to start showing "noticable" signs of working. Though the..... erm... non positive effects should start more or less immediately, if my body is susceptible to that.
19:23:13 <rust_collector> well, it did improve your spelling, so..
19:23:48 <Ysjoelfir> lol
19:24:42 <Ysjoelfir> brb, unloading the shopping trolley
19:26:25 <rust_collector> be careful, shopping trolleys and drugs do not mix
19:32:56 <Ysjoelfir> oh damn, am I going to die?
19:33:15 <rust_collector> nope, you are immortal now
19:33:37 <rust_collector> but you can ride the shopping trolley to town now
19:33:56 <Ysjoelfir> woah!
19:51:46 <Lemon> hi frens
19:52:10 <rust_collector> hey-oo
19:52:34 <rust_collector> so, did the french invent that hand stuck in glass prank?
19:53:16 <Ysjoelfir> hey melon
19:58:33 <Lemon> heeehh no idea rusty
19:58:50 <rust_collector> mmmh. ok
20:03:51 <Ysjoelfir> hmm..... I shouldn't notice anything yet, but my body definitely notices something. my blood pressure is through the roof :D
20:04:55 <rust_collector> oh, you might not get the effect you are after in a while, but yeah, you will notice something pretty quick
20:05:48 <rust_collector> not that I ever tried fancy stuff from the doctor, in doses that makes sense...
20:06:05 <Ysjoelfir> 155/93 with 77 pulse. thats... a bit higher than my usual :P
20:07:43 <rust_collector> when I was in.... I think 5th grade, the school nurse checked, and thought i had a pulse of 16. That was funny. she wrote it on the sheet, did some more tests, and read thru her paper, and thought that looked a bit unusual
20:07:57 <Ysjoelfir> lol
20:08:13 <Ysjoelfir> just a bit, yes :P
20:08:22 <Ysjoelfir> your heart was probably just lazy that day
20:08:45 <rust_collector> yeah. no need to stress, and if I do, I might get close to normal
20:11:54 <Lemon> I always had a pulse under average, for some reasons
20:12:14 <Lemon> every doctors since im born told me that, but it seems to not be a problem lol
20:12:20 <Lemon> im just a calm lemon
20:12:41 <rust_collector> yeah, it is not like it matters what number it is, as long as it works
20:15:00 <Lemon> yeah
20:15:14 <Lemon> so yesterday night I spent like, 2-3 hours with my shitty breadboards
20:15:36 <rust_collector> WOOHOO! 32 points for you
20:15:43 <Lemon> I used a sturdy pin from a small bulb to loosen every single holes
20:15:53 <Lemon> yes it was long, and boring
20:15:55 <Ysjoelfir> did that work?
20:16:02 <Lemon> it seems to be better yes
20:16:09 <Lemon> but they are really low quality anyway
20:16:11 <rust_collector> so, you just wiggled the contact things?
20:16:12 <Lemon> some are too lose
20:16:24 <Lemon> I inserted it and it was enough
20:16:25 <Ysjoelfir> didn't you want to get a nic twin industries or 3M one?
20:16:36 <Ysjoelfir> *nice
20:16:45 <Lemon> I do but either I cant order them because of lack of TVA number, or its super expensive on farnell
20:16:53 <Lemon> 60 euros without shipping for the one you have :(
20:17:19 <Lemon> but yes that would be ideal
20:17:27 <Lemon> then I linked three together
20:17:36 <Lemon> ha, mother is here, brb
20:17:44 <rust_collector> say hi to mom
20:19:21 <rust_collector> I messed with my breadboard yesterday too. so now I have both of the power side parts on one side, and it looks so weird
20:21:20 <Ysjoelfir> Rusty, speaking of power... I might start with your little task you gave me this weekend.
20:23:22 <K> twin industries on farnell for 8 and 11 eur
20:23:35 <K> dunno about fr but shipping to lv is 7 eur i thing
20:23:37 <K> tinkh
20:23:42 <K> ffs
20:23:44 <K> think
20:24:24 <K> i've thrown cheap ass chinese breadboard stright into trash after debuging some shit for 2 hours
20:25:17 <Ysjoelfir> yep... same. since I have the twin I get the impression that I have much less problems when breadboarding
20:33:00 <Lemon> 8 and 11 ? can you link it please ?
20:33:05 <Lemon> I have different prices

20:41:44 <rust_collector> uh, ok, Ysjoelfir, there is no rush. go the beach and grill stuff if you want
20:47:20 <Ysjoelfir> jeg har ikke strand
20:47:36 <rust_collector> humm
20:47:51 <rust_collector> that could take some time
20:48:46 <Ysjoelfir> probably
20:49:22 <rust_collector> if you push france a bit to the south, it should be close to the sea?
20:49:59 <Ysjoelfir> I would prefer to go north, its colder there :P
20:50:16 <rust_collector> well, we will see about that...
20:51:46 <rust_collector> so, the wife is in town, the load of stuff from mrs onion van is there... I wonder what kind of stuff I have to do to that thing now.
20:51:59 <Ysjoelfir> xD did it return to you?
20:52:07 <rust_collector> not yet
20:52:32 <rust_collector> she is moving to town here, so I am pretty sure I will have some visits from it
20:52:58 <Ysjoelfir> didn't she live high up north?
20:53:01 <rust_collector> I know it needs new door bottoms, especially after it went off road
20:53:09 <rust_collector> yes, nooooorth
20:53:40 <rust_collector> i don't know what the plan is now, I was supposed to go pick it up last weekend, but... no...

20:55:42 <rust_collector> the guy naming that place has as much humor as the guy that named greenland

20:57:21 <Ysjoelfir> eeeeeeeeeeh? wth :D
20:57:26 <rust_collector> sørøya
20:57:39 <rust_collector> sør øy a
20:57:54 <Ysjoelfir> yeah, saw it and then I got it. so.... eeeeeeeeeeeeeeeh? why would you call THAT island SOUTH island?
20:57:57 <rust_collector> hasvik means has bay
20:58:10 <rust_collector> has probably means nothing at all
20:58:11 <K> has sausage?
20:58:16 <Ysjoelfir> let me guess. hasvik doesn't has a bay
20:58:29 <Ysjoelfir> oh it has

21:21:08 <Ysjoelfir> I enjoy that
21:21:44 <rust_collector> oh, they are pretty good at whatever it is they do, but try to translate it
21:23:13 <Ysjoelfir> I just did. erm. yeah I see

21:27:30 <Ysjoelfir> thats also pretty nice
21:27:58 <Lemon> ha yes TW boards prices are without taxes
21:28:08 <Lemon> so its like 13-14 per breadbard

21:38:46 <Ampera> all the things \o/
21:38:53 <rust_collector> yes Lemon... that is a thing that exists, lol
21:38:53 <Ysjoelfir> that looks like a ballpen that had a liason with some plastic pancakes, Lemon
21:39:05 <Lemon> yes a bit lol
21:39:16 <Lemon> well I gave up the idea on building my own hv probe
21:39:24 <Lemon> doesnt sound economically viable, and safe
21:39:37 <Ysjoelfir> who needs safety anyways?
21:39:53 <Lemon> its always a nice thing
21:40:02 <rust_collector> not always.
21:40:18 <Ampera> yeah we should take all the seatbelts and airbags outta everything and ban traction control
21:40:25 <Ampera> the world would be such a better place for it
21:40:44 <rust_collector> nah, seat belts makes sense, but yes to the rest
21:41:13 <Ampera> but it's so cool when people instantly turn into soup when they hit the windshield
21:41:19 <Ampera> seatbelts take all the fun outta that
21:41:27 <rust_collector> well, airbags are ok, and these days, cars are made to expire before the airbags, so they should be ok
21:42:03 <Ampera> the way you do it is by having a car so big, and made out of so much steel, the other guy's car squishes down into a dime before you even notice
21:42:14 <rust_collector> mmhmmm
21:42:30 <rust_collector> CANYONEEEEEEROOOOOO
21:43:04 <Lemon> pfff I did 6-8 aerial/barrel rolls without airbags, at 150kph

21:43:41 Join: modrobert ([email protected]) to #EEVblog
21:43:42 <rust_collector> well, you know Ampera is in the us, so they have different airbags
21:43:56 <Ampera> yeah ours are made out of glass and pubic hair
21:44:06 <rust_collector> I don't doubt that
21:44:11 <Ysjoelfir> they have airbags that shoot you the dashplate with such a force into your face that your brain decorates the interior
21:44:21 <rust_collector> but us spec airbags are slower, and larger
21:44:42 <Ampera> obviously, we're slower and larger
21:44:58 <rust_collector> most americans are short, it says here
21:46:11 <Ysjoelfir> Ampera meant larger in the horizontal dimension
21:46:39 <Ampera> no I meant down there, but whatever

21:50:33 <Ysjoelfir> have enjoys
21:53:25 <Lemon> hey Ysjoelfir is there any brand of flux that you recommend ? I only have a old circular box that you dip your iron in, and its not practical
21:53:33 <Lemon> I wanted a pen, or a siringue
22:00:01 <Ysjoelfir> I make my own for general purpose. I don't use much flux though, only for SMD stuff
22:00:20 <Ysjoelfir> oh wait, I have a pen that I use from time to time
22:00:26 <Ysjoelfir> want me to check what that is?
22:03:53 <Lemon> ho if its nearby yes, if not don't spend time on it :>
22:04:03 <Lemon> it will be mostly for smd stuff yes

22:18:07 <Ampera> any container that stores flux is a flux capacitor
22:28:09 <DHess_US> That is going to be confusing when I refer to ferrite storing magnetic flux.
22:28:53 <rust_collector> ferrite capacitors are great
22:29:19 <DHess_US> Free space? Flux capacitor. Dielectric space? Flux capacitor. Anything? Flux capacitor.
22:29:43 <DHess_US> Air core inductor? Flux capacitor.
22:30:10 <rust_collector> that should make it easier
22:30:32 <Ampera> herb farms are thyme machines
22:52:47 <K> :|
22:55:46 <Nero_> hmm should I put unity gain buffers after my dac to isolate it or just use some big resistors
22:56:24 <Nero_> They will be connected to the gate biases of my chip, so I´m expecting pA currents
22:59:46 <K> less components, less noise
23:01:57 <Nero_> very good point
23:02:09 <Nero_> not entirely true though
23:02:26 <Nero_> Just look at how much transistors they stuff into low noise amplifiers, way more than my standard gain cells
23:06:26 <K> bigger the resistance, more the noise, right?
23:06:48 <K> hm or was it the other way around
23:08:17 <K> yes
23:08:45 <K> wirewound resistors for great justice!
23:14:04 <Nero_> yeah, higher node impedance has more voltage noise
23:41:59 <DHess_US> The only reason to buffer the DAC like that is to reduce output impedance, or to implement remote sensing to remove common mode nmoise.
