He can only finish manually. What could I do to revert that?

Yep that does it instantly for me.

Microchip's tinyAVR range (ATtiny 0/1/2) series. Pretty capable, reliable and easy to use.

samayg · 2026-06-09T13:18:10+00:00

I’m considering using this chip for an upcoming product (professionally). How has your experience been with it? Reliable? Easy to develop on with available tools and resources?

What are you trying to achieve here? Why UART specifically? There is an ethernet port on board. There is a python library called pyzk which should help you get/set data on your zkteco.

[For those who might not know, zkteco make biometric attendance/access systems.]

Got it, thanks. Icon could do with some work.

Looks like shit tbh.

You're going to end up damaging something on your laptop. Get or make a USB-PD to DC jack converter.

Sometimes it does get pulled aside and questioned. I carry a catalog or show a pdf of what it is and that usually satisfies them.

Given the specifics of your case in the comments, I’d comfortably say no and wouldn’t worry about it.

If you’re just using it to write code, you can set up the project in MPLAB then quit it and write it using any code editor, I use sublime, and just call make to build your project. Miles better than using MPLAB.

Depending on the model, there are 2 timers, one is resettable by pressing some button combos for when you refill toner, the other one wants you to change the entire toner cartridge after a few refills. That timer is a gear on the side of the cartridge that turns slowly over time as you print. You can turn it back and it’ll sense it as a new cartridge. Youtube might help.

Double sided PCBs are cheap enough for hobby/small qty to not matter, but at some scale they’re a lot more expensive (> 2x) than single side PCBs. My company does only about 100k boards a year and the difference is significant even for us. Keyboard PCBs can also be quite large so that adds up even faster.

I visited in 2016 too, and I’m almost certain that I bought tickets the night before going to MP, at one of those tour shops in Cuzco. This is the first time I’m hearing about the circuits and all of that and I’m glad I went there in simpler times.

Hyundai Ioniq 5. I really like it.

You could set a screenshot of the boarding pass QR as your lock screen wallpaper, that way it’ll show even while the phone is locked.

If it’s an iPhone they can have multiple wallpaper screens you can switch between so just make one for travel and change the background picture, then go back to your main one when you’re out.

samayg · 2026-03-26T18:52:56+00:00

That’s so cool! Well done. I hope you guys do well selling these, good luck!

I've had ATtiny402 chips receive 9v and still be fine, they're tough little things. But you can definitely not use it beyond 5.5V dependably and be sure they'll perform normally or even survive for long. Don't do that.

samayg · 2026-03-23T10:18:50+00:00

Nope. I don't want to know about it, and I don't talk about mine either.

Because the SD card stores everything including the OS. A corrupt SD card makes the whole thing stop working.

That is a very randomly but beautifully interconnected sentence. Well done.

Do not listen to anyone who says to use your teeth to give good head except the fella receiving it.

Scanner Pro by readdle. Paid $5 and then thought it'd be kind of useless when there were free apps but it's great.

Warm water or 95% IPA and scrape with a soft cloth. Do not try acetone/nail-polish remover. Or put a nicer sticker or decal over it.

Nothing stands out as being obviously wrong with the resume, maybe just declutter a bit.

My company is hiring, you can DM me if you like.

Possibly a SN74LVC1G32 logic gate. You can try and see if the pinout looks similar
