12:11 AM retrosenator: i can't get atmega328
12:20 AM retrosenator: no stock
12:21 AM Rhine_Labs: WTF is up wiht my keyboard brb
12:24 AM Rhine_Labs: Back
12:26 AM Rhine_Labs: My 2 modern Xeltek programmers https://www.stevenrhine.com/wp-content/uploads/2021/10/20211010_2234511-1024x576.jpg
12:27 AM Rhine_Labs: I am a harware guy not a coder LOL i dabble but just can never get it down.
12:30 AM Rhine_Labs: Yea, the programmer I use supports 103466 chips.
12:34 AM Rhine_Labs: type in the settings no lock bits hit ok then program security on main screen done.
12:34 AM Rhine_Labs: https://www.stevenrhine.com/wp-content/uploads/2022/03/atmega328fusebitsxeltek.jpg
12:44 AM Rhine_Labs: Yea, i killed a 328 24V 3.2A oops
12:45 AM Rhine_Labs: Double check PSU before turning on LOL
12:46 AM Rhine_Labs: I replaced chip but cannot load firmware because it uses HIDBootload
12:46 AM Rhine_Labs: https://www.stevenrhine.com/wp-content/uploads/2022/03/Flasher-File-Loaded.png
12:47 AM retrosenator: 24v?!
12:47 AM retrosenator: dam
12:48 AM Rhine_Labs: Yea, magic smoke LOL
05:00 AM specing_ is now known as specing
12:25 PM polprog: WormFood: never heard of it
12:30 PM WormFood: polprog, yeah, it was a new one for me too. But at least I got to learn something new. I had no idea they were doing that kinda stuff with PLLs.
12:30 PM polprog: What is that from?
12:31 PM WormFood: It's a technique used on the loops on a PLL (Phase Lock Loop)
12:31 PM WormFood: I didn't dig deep enough to truly understand it in detail, but I get the gist of it.
01:45 PM polprog: sounds interesting
02:19 PM WormFood: I'm working on a possible PLL design in my head, and I thought that info may come in handy, but I'd never head of a swallow counter before. It seems not many people are aware of it.
02:27 PM exp: Rhine_Labs: if nobody helps you by tomorrow, give me a shout
02:27 PM exp: i am happy to compile things, just rather busy myself
02:31 PM Rhine_Labs: ok
02:41 PM Rhine_Labs: exp thanks will be in touch.
04:59 PM specing_ is now known as specing
08:18 PM rue_bed2: let me guess, you need a way to apply 24V to an avr without it blowing up?
08:18 PM retrosenator: ?!?
08:18 PM rue_bed2: exp, see hisotry
08:18 PM retrosenator: do they make a new avr that can run at 24v?
08:19 PM retrosenator: would be a amazed
08:19 PM retrosenator: what i do
08:19 PM retrosenator: is use a buck converter thing
08:20 PM rue_bed2: ever measured the efficiency of one of those?
08:21 PM retrosenator: yes i do
08:21 PM retrosenator: in fact, what I check for is something called "pulse skipping"
08:21 PM rue_bed2: what do you get?
08:21 PM retrosenator: and bootstrap
08:21 PM retrosenator: i get 95% efficiency
08:21 PM rue_bed2: I know pulse skipping well
08:21 PM retrosenator: supplying 5mA
08:22 PM rue_bed2: I use it on my 555 controlled suplies
08:22 PM rue_bed2: 5mA!
08:22 PM retrosenator: sorry
08:22 PM rue_bed2: how about 100mA?
08:22 PM retrosenator: 15mA at 5v
08:22 PM retrosenator: and bootstrap uses a high-side n-fet
08:22 PM rue_bed2: so your not talking the cheap ones from china..
08:22 PM retrosenator: yeah it can easil do that
08:22 PM retrosenator: the pulse skipping enables high efficiency at really light currents
08:22 PM retrosenator: well
08:22 PM retrosenator: it comes from china
08:22 PM retrosenator: but
08:22 PM retrosenator: the part is not chinese no
08:23 PM retrosenator: they just stock it and put it on the board
08:23 PM retrosenator: the part is not that expensive
08:24 PM retrosenator: and I use like a 3 amp inductor
08:24 PM retrosenator: even though my current is < 50mA
08:24 PM retrosenator: this gives a higher efficiency
08:24 PM retrosenator: LMR14030
08:25 PM retrosenator: now if you mean the modules ...
08:26 PM retrosenator: yeah those are low efficiency
08:26 PM retrosenator: i nearl burned one up had to add heatsinks etc, and that was at 1/3rd the "rating"
08:34 PM mikee is now known as saxicola
10:58 PM otty: hey
10:58 PM otty: anyone know about 8086?
11:04 PM qu1j0t3: idk there might be a better channel for that
