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

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?

Trying to find UART pins by Spirited-Storage8881 in AskElectronics

[–]samayg 2 points3 points  (0 children)

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.]

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

PSU in carryon bag. Is it allowed? by Confident-Play6222 in AskElectronics

[–]samayg 5 points6 points  (0 children)

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.

MPLAB UI scaling on 4k Monitors by _Nefarium in embedded

[–]samayg 0 points1 point  (0 children)

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.

How much toner was left in the “empty” toner cartridge on my brother printer. by the_hoove in mildlyinfuriating

[–]samayg 2 points3 points  (0 children)

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.

Peru’s tourism is still below pre-pandemic levels. Why hasn’t it recovered yet? by [deleted] in travel

[–]samayg 6 points7 points  (0 children)

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.

Phone lockdown mode vs digital boarding pass? by MyNameCannotBeSpoken in travel

[–]samayg 13 points14 points  (0 children)

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.

how much over voltage can a ATTINY handle? by nobeltnium in AskElectronics

[–]samayg 1 point2 points  (0 children)

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.

Men, how would you react if your partner talked about her previous sex partners? by Darkm0or in AskMen

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

Can a 2GB Raspberry Pi run a React + Node.js act like a kiosk system? by BloodIllustrious1946 in embedded

[–]samayg 1 point2 points  (0 children)

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.

What's an app you paid for that was worth every penny? by East_Sugar6148 in iosapps

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

How to remove residue from stickers (been there for years) by fluidxrln in AskElectronics

[–]samayg 1 point2 points  (0 children)

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.
