01:54 AM rue_bed: akaWolf, cehteh inflex jadew mulvane nuxil Thrashbarg theBear got any avr projects going latley?
01:58 AM rue_bed: alx741, what kinda avrs you working with?
01:58 AM rue_bed: Ameisen, you programming in C or C++?
01:58 AM rue_bed: andreas303, do you do custom pcbs?
01:58 AM rue_bed: Apocx, how long you been here now?
01:58 AM rue_bed: arti, you making robots?
01:58 AM rue_bed: Ashleee, what timezone ya in?
01:58 AM rue_bed: atk, know any good libraries?
01:58 AM rue_bed: bleb, you doing any usb programming?
01:59 AM rue_bed: dan2wik, use avrs at work?
01:59 AM rue_bed: davor, work with stm32 at all?
02:00 AM rue_bed: day, what timezone ya in?
02:00 AM jadew: rue_bed, rue_bot?
02:00 AM rue_bed: dev1990_, long time no hear, what you doing?
02:00 AM rue_bed: jadew, how so?
02:00 AM jadew: didn't know what's happening, hehe
02:00 AM rue_bed: what you working on latley?
02:01 AM rue_bed: I was doing a force feedback servo today
02:01 AM rue_bed: djinni, do anything battery powered?
02:01 AM jadew: I play mostly with RF these days, but yeah, I do use AVR from time to time, nothing at the moment tho
02:01 AM rue_bed: dunz0r, have you done anything with rf?
02:01 AM rue_bed: what kinda rf?
02:02 AM rue_bed: 88mhz?
02:02 AM rue_bed: 10Mhz :)
02:02 AM jadew: DC to 10 GHz
02:02 AM rue_bed: eballetbo, what kinda things do you do?
02:02 AM rue_bed: jadew, DC is a touch RF :)
02:03 AM rue_bed: ephemer0l, ever worked with IR remotes?
02:03 AM rue_bed: jadew, you making 10Ghz circuits or just using them?
02:03 AM jadew: ah, I made an IR remote about two weeks ago
02:03 AM jadew: with an AVR
02:03 AM rue_bed: cool, I did a both-ends, with some t13
02:04 AM inflex: haven't done a thing in a long time
02:04 AM rue_bed: running the tx on a 3V cd2032 was fun
02:04 AM inflex: Been too busy doing software (OpenBoardview and FlexBV) and fixing macbooks
02:04 AM rue_bed: I check which io pin is powering the avr :)
02:04 AM rue_bed: openboardview?
02:05 AM inflex: Lets you locate parts and nets on boards you're repairing, for many computers
02:05 AM rue_bed: Evidlo, how about you? stm32?
02:06 AM rue_bed: inflex, oh, you import the images and ir overlays!
02:06 AM rue_bed: ?
02:06 AM rue_bed: Fleck, you havn't said much latley, whats up?
02:06 AM rue_bed: flip214, what kinda stuff do you do?
02:06 AM rue_bed: FManTX, whats your favorite avr?
02:07 AM inflex: rue_bed, more like this; http://pldaniels.com/flexbv/sample1.png
02:07 AM rue_bed: FozzWorth_, you getting into microcontrollers or already work with them?
02:07 AM inflex: rue_bed, not much really of use when you're designing/building boards, but very useful when you're diagnosing/repairing.
02:08 AM rue_bed: so, its not reverse engineering then, its got the board data
02:08 AM rue_bed: Frans-Willem, not Fran, right?
02:09 AM rue_bed: FrozenDroid, can you type? say something!
02:09 AM rue_bed: funky1, done any flashing led stuff with avrs?
02:09 AM rue_bed: inflex, so, you one of the official apple repair peoples then?
02:10 AM rue_bed: fus, you in germany?
02:10 AM inflex: rue_bed, yes, the boardview files have pins, nets, positions in them, and my software heuristically generates the parts and links it all together; as an addition I now have created a link to the PDF files too so you can more quickly skip back/forth. Anyhow, it's not something that seems to make a lot of sense until you start doing the repair jobs
02:10 AM inflex: rue_bed, hah, hardly, more of an officially unofficial repairer. T
02:11 AM rue_bed: ah, your the person who dosn't just say "buy a new one"
02:11 AM rue_bed: gambakufu, whats your interest in avrs?
02:11 AM inflex: rue_bed, correct. I do a lot of YouTube videos now
02:11 AM rue_bed: gruetzkopf, you working with 8 bit or 32 bit avrs?
02:11 AM rue_bed: ah cool
02:12 AM inflex: https://www.youtube.com/user/19PLD73
02:12 AM rue_bed: HighInBC, bc canada?
02:12 AM rue_bed: I cant youtube, they dont like my computer
02:12 AM rue_bed: impulse, you do any 1 day projects?
02:13 AM rue_bed: iSaul, and what kinda stuff do you do?
02:13 AM rue_bed: jadew, did you make a transmitter or reciever then?
02:13 AM rue_bed: jaagr, do you do robots?
02:14 AM rue_bed: JanC, got any good projects on the go?
02:14 AM jadew: rue_bed, are you trying to wake everyone up? :)
02:14 AM jadew: I did both
02:14 AM rue_bed: yes, partly
02:14 AM rue_bed: jadew, did you use the timer to generate the 32Khz or something else?
02:15 AM rue_bed: jesseg, do you know any good motor driver boards?
02:15 AM rue_bed: johnbeard, what are you looking to use avrs for?
02:15 AM rue_bed: jragon, what programming languages you use?
02:16 AM rue_bed: Kevin`, ever do any competition robotics?
02:16 AM rue_bed: jadew, did you use the timer to generate the 32Khz or something else?
02:16 AM rue_bed: for the ir tx modulation
02:16 AM rue_bed: kiki_lamb, interesting nickname, does it have a background?
02:16 AM jadew: rue_bed, there was no RTC, but why would you use the timer to do that?
02:17 AM rue_bed: jadew, no the ir tx modulation
02:17 AM jadew: normally the point is to have the RTC running on its own, when everything else is off, so you'd need an external crystal
02:17 AM jadew: ah
02:17 AM rue_bed: I presume you used modulated ir?
02:17 AM jadew: you mean about the remote
02:17 AM jadew: yeah
02:17 AM rue_bed: yea
02:17 AM jadew: I use the timer and toggled the output pin on and off
02:18 AM jadew: worked great
02:18 AM rue_bed: cool, yea
02:18 AM rue_bed: I used a sony protocol
02:18 AM rue_bed: which did you use?
02:19 AM rue_bed: kini, what kinda avrs you looking at?
02:19 AM jadew: I don't know what protocol this was, I just recorded the data and made a program that encoded and packed the stream
02:19 AM jadew: then flashed that with the firmware and played it back
02:19 AM rue_bed: record on/off times?
02:19 AM jadew: yeah
02:19 AM rue_bed: huh
02:19 AM rue_bed: yea, I made a reciever for a sony remote, then made a tx that did the same codes
02:20 AM rue_bed: 3d printed a 2 button remote to turn my bedroom lights on and off
02:20 AM rue_bed: the cr2032 is still going
02:20 AM rue_bed: lemmings, hello?
02:20 AM rue_bed: leptonix, I'v not heard from you yet, what kinda things you doing?
02:21 AM rue_bed: lerc, do you do robotics?
02:21 AM jadew: how much current can you draw from the cr2032?
02:21 AM rue_bed: :) I think the resistor for the led was like 22 ohms
02:21 AM jadew: so... all :P
02:21 AM rue_bed: over 30mA fore sure
02:22 AM rue_bed: its a pretty quick burst,
02:22 AM rue_bed: thankfully the reset voltage on the avr is so low
02:22 AM jadew: yeah, if it's decoupled it wouldn't matter
02:22 AM rue_bed: lifeeth, you doiing ai on avrs?
02:23 AM rue_bed: lvlinux, what you looking at doing with avrs? kernel stuff?
02:23 AM rue_bed: markus-k, doing any radio stuff with avrs?
02:23 AM rue_bed: merethan_w, how about you? work with stm32?
02:23 AM rue_bed: mindw0rk, let me guess, ai?
02:24 AM rue_bed: jadew, what did your ir stuff do?
02:24 AM jadew: controlled the lights hehe
02:24 AM day: rue_bed: +1
02:24 AM rue_bed: MrFahrenheit, when was the last time you said anything?
02:24 AM rue_bed: hah, really??? what kinda lights?
02:25 AM rue_bed: day, oof, I'm -8
02:25 AM rue_bed: I cant sleep
02:25 AM jadew: rue_bed, those remote controlled light bulbs
02:25 AM rue_bed: day, what kinda avr stuff do you do?
02:25 AM rue_bed: oh, I thought they were all rf?
02:26 AM rue_bed: /bluetooth/wifi
02:26 AM jadew: I guess not all
02:26 AM jadew: the IR ones are very cheap, don't know about the other ones
02:26 AM day: havent really done anything in a while. cant think of any projects worth doing :(
02:26 AM jadew: I paid about $10 / light bulb
02:26 AM rue_bed: day, like robotics?
02:26 AM rue_bed: jadew, are they ok lightbulbs?
02:27 AM jadew: rue_bed, not really
02:27 AM rue_bed: mulvane, do you have any projects on the go?
02:27 AM jadew: poor color index and a bit on the warm side
02:27 AM rue_bed: hmm
02:27 AM jadew: they're not awful tho
02:27 AM jadew: I had awful and this is not it
02:28 AM rue_bed: nabil, what stuff do you do?
02:28 AM rue_bed: jadew, are they colour selectable?
02:28 AM jadew: yeah
02:28 AM day: rue_bed: i pretty much just got curious about how to work with µC's after i figured the basics out i realized that usually china already offers what you want to build for 1EUR incl. shipping :P
02:28 AM rue_bed: nikomo, have you controlled leds with an avr in any of your stuff?
02:29 AM rue_bed: day, yes, but programming them is the fun part
02:29 AM rue_bed: njbair, have you worked with avrs at all?
02:30 AM rue_bed: nohit, have you done any robotics???
02:30 AM rue_bed: ohsix, what do you do?
02:30 AM rue_bed: pepijndevos, how about you, worked with remotes/wireless/robotics?
02:31 AM rue_bed: phragment_, gamer?
02:31 AM rue_bed: pingo, what microcontrollers have you worked with?
02:31 AM rue_bed: pitastrudl, what programming languages do ya know?
02:32 AM rue_bed: pwillard, you a programmer?
02:32 AM rue_bed: Quantumc1, know anything about motor control?
02:32 AM rue_bed: ravon, what kinda avrs you into?
02:33 AM ravon: rue_bed: AVR32
02:33 AM rue_bed: day, so, you havn't used any microcontrollers yet?
02:33 AM rue_bed: ravon, ah, worked with them long?
02:34 AM ravon: rue_bed: Probably 5-or-so years
02:34 AM rue_bed: riotz, do you have any good projects you can share?
02:34 AM rue_bed: ravon, cool, what kinda hardware you operating?
02:35 AM rue_bed: rue_bed, go to sleeeeeeeeeeep
02:35 AM rue_bed: s8548a, you nick sounds like an RF chip...
02:35 AM rue_bed: SebastianFlyte, do you already work with avrs or you just looking to get into them?
02:36 AM rue_bed: shifttymike, avr for hacking?
02:36 AM s8548a: rue_bed: :)
02:36 AM rue_bed: its a guess, am i right?
02:36 AM s8548a: thats just my name as in phone keypad
02:36 AM rue_bed: huh, dont know that one, what you doing with avrs?
02:37 AM rue_bed: or not..
02:37 AM day: rue_bed: i built the mandatory nixie clock. :P
02:37 AM rue_bed: Smasher816, whats your favorite avr?
02:37 AM rue_bed: day, hah, where did you source tubes?
02:37 AM s8548a: nothing, I use microchip, that too very rare, I do mostly pcb designing
02:37 AM day: ebay?
02:38 AM rue_bed: Snoras, have you made a nixie clock?
02:38 AM rue_bed: s8548a, commercially?
02:38 AM s8548a: yes
02:38 AM rue_bed: avrs are better than pics ya know :)
02:39 AM day: i dont think the pcb designer cares \o/
02:39 AM rue_bed: no paging, no clock divider...
02:39 AM s8548a: i dont want a storm here ;)
02:39 AM rue_bed: no stupid resets cause of tiny amounts of noise
02:40 AM rue_bed: specing, hey, when was the last time you said something
02:40 AM rue_bed: splud, tell us about your avr project dreams
02:40 AM rue_bed: sunri5e, you done any avr programming yet?
02:40 AM day: anyhow at this point i would just go with ARM instead of avr for personal projects
02:41 AM rue_bed: s8548a, so, your here more as a general interest in microcntrollers
02:41 AM rue_bed: day, stm32 perhapps
02:41 AM s8548a: yes
02:41 AM rue_bed: s8548a, you wouldn't happen to maybe design HP boards eh?
02:41 AM day: rue_bed: yes, i have a nucleo discovery board :). but most of my work was done for a nxp chip
02:42 AM davor_ is now known as davor
02:42 AM rue_bed: NXP, say, like.,.. 8951?
02:42 AM s8548a: no
02:42 AM rue_bed: haha
02:42 AM rue_bed: oh cmon, she's a classic
02:42 AM day: ah no. nxp arm. i forgot the exact name
02:43 AM rue_bed: the stm32 is ok , cheaper than avrs and... more advanced
02:43 AM rue_bed: 72Mhz
02:43 AM rue_bed: oh, damn, who was I at....
02:44 AM rue_bed: t0mmy, do you use avrs for robotics perhapps?
02:44 AM rue_bed: testriotewq[m], is there an array of you?
02:44 AM rue_bed: ThatDamnRanga, whats a ranga?
02:45 AM rue_bed: The_Coolest, are you working on anything cool?
02:45 AM rue_bed: s8548a, do you prefer hand routing, auto, or a mix?
02:46 AM rue_bed: Thymo, what kinda programming do you do?
02:46 AM rue_bed: tpw_rules, you have also not said much latley, whats up?
02:46 AM rue_bed: troyt, whats your interest in avr?
02:47 AM rue_bed: ub|k, you into electronics? programming?
02:47 AM rue_bed: vishwin, what do you use controllers for?
02:47 AM rue_bed: vmt, have you worked with stm32?
02:47 AM rue_bed: x7C3, made any libraires for avr stuffs?
02:48 AM rue_bed: xMopx, ever written manchester code?
02:48 AM rue_bed: zopsi, you getting started with avr or what?
02:48 AM rue_bed: I cant find the bracket on my laptop, gonna have to turn on a light...
02:49 AM rue_bed: [1]MrMobius, you do any drafting?
02:49 AM rue_bed: s8548a, ?
02:50 AM rue_bed: I prefer hand routing cause I can do things like reposition parts,
02:50 AM rue_bed: I'm not aware of an autorouter that can do minor component relocations
02:58 AM mindw0rk: rue_bed: mindw0rk, let me guess, ai?
02:58 AM mindw0rk: no, actually emulating and making hardware for gameboys
03:24 AM ub|k: ub|k: yeah, i'm into both
03:33 AM s8548a: rue_bed: manual, sometimes auto for a quick checking only
04:19 AM lerc: mindw0rk: avr powered gameboy?
05:16 AM cehteh: rue_bed: i am just back from vacation
05:39 AM Stormpie: hi looking at some code for attiny and found the following lines pre() post() and writes() immediately after the function declaration. Any idea what this actually does?
06:01 AM The_Coolest: rue_bed>> Not working on anything cool at the moment :P
06:02 AM The_Coolest: Gonna have to add support for another e-ink display to my driver when I get it, but it should be relatively easy. Just need to find a 40x80 pixel font for it.
06:24 AM pwillard: Autoroute? NEVER!
08:51 AM rue_mohr: mindw0rk, emulating the z80 or the perphials?
08:52 AM rue_mohr: The_Coolest, 40x80?
08:52 AM rue_mohr: per character?
09:11 AM jesseg: rue_bed, rue_mohr rue_shop3 wherever you are -- what sort of motor driver? stepper or DC?
09:16 AM jesseg: rue_bed, I usually need DC motor drivers, and usually use IRF2104 based fet setups
09:20 AM rue_mohr: I'm doing dc now
09:20 AM rue_mohr: but small
09:20 AM rue_mohr: jesseg, how large are the dc motors you have done drivers for?
09:22 AM jesseg: rue_bed, oh small, usually 48v pitmans or whatnot. The fets I usually use are rated at like 200v and 30A, but I've never run them near that, nor have the PCBs been designed for that much power
09:22 AM jesseg: but I like my motor drivers to run cool :D
09:23 AM jesseg: rue_mohr, I was beginning to experiment with driving a 48V 1/4HP dc motor but never followed through with it
09:24 AM rue_mohr: those are moderatly large
09:24 AM jesseg: yeah but most of my stuff has just been little motors for small CNC stuff
09:24 AM rue_mohr: did you do current limiting?
09:24 AM rue_mohr: ah, servo drives then
09:24 AM jesseg: no I did not any current limiting. It was just for hobby stuff and I was in a hurry :P
09:24 AM mindw0rk: rue_mohr: hardware mainly to interface with the peripherals, cartridge slot and serial port
09:25 AM jesseg: yeah I'm one of those annoying anti-stepper junkies
09:25 AM rue_mohr: me too technically
09:25 AM rue_mohr: tho those new stepper drivers can get those motors to do pretty insane things
09:25 AM rue_mohr: I think I had a nema 32 doing about 300rpm
09:26 AM jesseg: lol with an encoder?
09:26 AM rue_mohr: no
09:26 AM rue_mohr: compared to unipolar votlage drivers...
09:26 AM jesseg: ahh just with minimal load and high voltages :D
09:27 AM rue_mohr: I have a series of m32 based servo controllers
09:27 AM rue_mohr: aka motor and feedback
09:27 AM rue_mohr: some digital, some analog
09:28 AM rue_mohr: yesterdays achivement was a force-feedback digital set
09:28 AM rue_mohr: http://ruemohr.org/~ircjunk/projects/servo/p1100692.jpg
09:29 AM jesseg: haha cool
09:29 AM rue_mohr: using audio amps as drivers :) (current controlled, serial I/F w/ 595 and DAC)
09:30 AM rue_mohr: I"v done a few things
09:31 AM rue_mohr: http://ruemohr.org/~ircjunk/projects/servo/p1020396.jpg
09:31 AM rue_mohr: that one was insane
09:31 AM rue_mohr: standard solinoid, linear encoder from a printer
09:31 AM rue_mohr: I had to do some special code to deal with the insane nonlinearity of the solinoid
09:31 AM jesseg: lol no kidding
09:32 AM rue_mohr: what kinda feedback you working with?
09:33 AM jesseg: just optical incremental encoders or sometimes magnetic incremental encoders (quadrature in all cases) -- whatever happens to be on the surplus servo motors I get off ebay
09:34 AM jesseg: although my "new" (1996 erra) tiawanese mill has linear "saphire" inductive based DRO on it so it's possible I may try to interface to that at some point
09:35 AM rue_mohr: off to work bbl
09:38 AM merethan_w: I still can´t get my head around volatile, and its purpose. I do understand not using it in the right situation might b0rk things regarding ISR´s and variables. But does using it too often hurt in any other way than possibly performance?
09:39 AM jesseg: nope
09:40 AM jesseg: I doubt it hurts performance either, but it may grow code size a bit.
09:40 AM jesseg: I dunno it may impact performance. It simply prevents the compiler from optimizing out references to the variable.
09:41 AM cehteh: it hurts performance and grows code, you have to understand how it works and use it correctly
09:42 AM jesseg: Basically, the compiler looks at each variable to see if it's actually used in a function that actually gets called. Since the ISR doesn't get called from any user code the compiler thinks the ISR never gets called and thus may not allocate variables that are only used in the ISR or something of that theme
09:42 AM cehteh: there is more to it, about reodering and other optimizations
09:43 AM cehteh: still when a variable is shared between ISR and non ISR code you must define it volatile, but sometimes its better just to copy its value into some local variable
10:03 AM The_Coolest: rue_bed>> Yes, per char.
10:03 AM The_Coolest: For my 200x200 I'm currently using 32x64, and could really use 40x80, but couldn't find any.
10:04 AM The_Coolest: Using the Grotesk fonts from here: http://www.rinkydinkelectronics.com/r_fonts.php
10:04 AM The_Coolest: 200x200 e-ink: https://discourse.coreelec.org/t/lepotato-openvfd/974/8?u=thecoolest
12:24 PM flip214: rue_bed: dimming LEDs via an infrared.
01:08 PM nabil__ is now known as nabil
03:24 PM DelphiWorld: yo
03:24 PM DelphiWorld: cehteh: where's the blind people you told me here?
03:29 PM cehteh: mhm jan- from arduino .. but she isnt online now, and i've spoken to few more but cant remmember the nicks
03:30 PM cehteh: well often people dont tell you, but i met blind programmers a few times on irc
03:31 PM DelphiWorld: i see, cehteh
03:33 PM cehteh: do you use text to speech for programming too, or a braille line?
03:33 PM DelphiWorld: cehteh: text to speech
03:33 PM DelphiWorld: brail display is super expancive
03:33 PM cehteh: ah i didnt know
03:34 PM cehteh: mhm building a cheap one as open source w/ 3d printer and stuff would be cool
03:34 PM DelphiWorld: it would be awesome
03:34 PM DelphiWorld: because the actuals is very expancive for a very low manufacturing cost
03:35 PM cehteh: actuals? actuators?
03:35 PM DelphiWorld: i mean for there manufacturing price
03:36 PM cehteh: well having some acutator for each 'pixel' looks like it would drive the costs to me
03:36 PM cehteh: and i am not much into that dunno how that actually works and where to get these and what the alternatives are
03:51 PM [1]MrMobius is now known as MrMobius
07:24 PM rue_shop4: merethan_, volatile means that it reloads the value from memory every time it goes to use it instead of using its cached version
07:25 PM rue_shop4: for example, if you have i=1; while(i);
07:25 PM rue_shop4: if i is not volatile and you change it to 0 in an interrupt, the loop will not break
07:25 PM rue_shop4: cause the compiler has the cpu using the cached version of i
08:29 PM splud: rue_shop4 - you a different console for rue_bed and rue_work ?
08:29 PM splud: er, rue_mohr ?
08:37 PM splud: I'll presume you are. Saw the sequence of blasts to various idle nicks many hours back. If you check, you might note some are marked "away".
08:38 PM splud: This channel isn't particularly active, but I like parking here so I can check on activity every so often (more than the constant join/quit/timeout stream).
08:40 PM splud: to the query posted earlier, I'm in the midst of doing finish work on my workshop office space, so haven't been making progress on electronics projects like I would like to, so nothing very "active" right now. In a few weeks, hopefully I'll be back to it (and have less dust in my life)
08:40 PM rue_shop3: splud, yea!
08:41 PM splud: ATTiny85 and 84 are both nice AVRs for small projects, but I've done a ton of stuff with ATTiny13A
08:41 PM splud: and have tinkered with ATTiny10, 24V, and 43U (besides a host of others).
08:41 PM rue_shop3: I'v had a number of applications for the 13A, but its a bit of a challange, I'm usually over by 1 io pin
08:42 PM rue_shop3: do you usually repurpose the reset and use HV programming?
08:42 PM splud: 43U has a built-in boost controller. I have one sitting at my desk that has been running off a single AA cell that was partially depleted at the start sometime in early February - 1320mV, and a couple of days ago measured at 1299 mV.
08:43 PM rue_shop3: do you have it doing much?
08:43 PM splud: It isn't doing much, but is flashing an LED to say it is still going, once about every 17 seconds.
08:43 PM rue_shop3: hah, nice
08:43 PM splud: (and then sleeping, and waking a few times, then going "time to flash"). Still, one duff battery...
08:43 PM rue_shop3: is it sleeping in between?
08:43 PM rue_shop3: ah
08:44 PM rue_shop3: cool
08:44 PM rue_shop3: what clock speed?
08:44 PM rue_shop3: rc?
08:44 PM splud: Have another sitting outside, with an ultracap and small solar cell, doing the same thing, but strictly solar.
08:44 PM splud: Lemme check the makefile.
08:45 PM rue_shop3: I did a solar light controller, didn't use a uC, but had a hell of a time keeping the power down
08:45 PM splud: 1MHz
08:45 PM rue_shop3: pretty good for the draw!
08:46 PM rue_shop3: I got a 100F ultracap and, after playing with it for a bit put it in a "dangerous" bin :)
08:46 PM rue_shop3: IT JUST KEEPS GIVING
08:47 PM splud: no uC tinkering, but reverse engineered the control circuit on my porch lamp so I could tap in a second PIR module (and will add a third in the spring), so that it comes on from activity out in the driveway (and eventually between the house and workshop), while maintainint it;s timing and light sensitivity.
08:48 PM splud: And, because I tapped into the control circuit, I _could_ add a networked remote control to it, though I wouldn't be using an AVR for that task.
08:49 PM splud: I have a bunch of 5V 1.5F and a few several farad 2.7V, and one honkin several hundred F 2.7V
08:49 PM splud: I think 700F ?
08:50 PM splud: I laid out the PCBs for the 43U with support unductor and caps, etc, earlier this year - I finally got hold of a few of the uCs last year and then didn't have the time to tinker with them.
08:51 PM splud: I churned short run builds of a number of PCBs earlier this year.
08:55 PM splud: I have a bunch of the 13A - 1KB flash, and 64 bytes of RAM. Very handy and minimal. PWM controller for a homebrew hot wire cutter, modded to run a wood smoker, controller for a mains outlet.
08:56 PM splud: that's two separate projects, not the same PCB.
08:57 PM splud: controller for mains outlet has the uC powered from the mains, driving a triac - button switches it on, drives the LED, at a certain point, starts flashing the LED, and a while later, flashing it faster, then switches off, unless button pressed again to reset the timer.
08:58 PM splud: Handy for controlling an outlet for a cheap soldering iron or hotmelt glue gun. SAME PCB can be flashed with a different load, and instead, the button causes it to power off the outlet for 15 seconds (a remote device power cycle).
09:00 PM splud: Or, detect loss of power (by merit of resetting), and hold the output off for a predefined period (say 5 minutes) - if power is reset during that time, the count would start over. This keeps a machine from partly rebooting and then getting power cycled again because mains failures all too frequently (around here at least) aren't 100% restored the first time the power is switched back on. Button can cause it to power on NOW instead
09:00 PM splud: of waiting.
09:01 PM splud: I like how the same PCB design can just be flashed with different code and be a totally different device as a result.
09:06 PM splud: and away I go.
09:08 PM rue_shop3: who did you do the pcbs with?
09:09 PM rue_shop3: splud, yea, I can see using a "clean powerup" controller for some of my stuff
