yeah, the ESP line is my go to these days for stupid poo poo. they're priced pretty close to the arduinos, but faster and usually have wifi and/or bluetooth. It's a little finicky to set up, but the fact that you can program them directly in the arduino environment is useful for hacking something together, with the large library support arduino has. But, if you want to get deeper into it, there's a handful of C compilers that will work with.

That big clock i've been working on uses the older ESP8266, simply because i had a few lying around. (although, i'm trying to design it to be MCU agnostic, since it's all serial communication anyway)

edit: how to set up the arduino ide to use ESP32 - https://randomnerdtutorials.com/installing-the-esp32-board-in-arduino-ide-windows-instructions/

yeah wow i need to look into these. sound perfect. arduino is the perfect amount of not complex to get running

thankyou for showing me these! exactly what I wanted. but a quick search shows me imma have to spend a bit of time trying to work out what’s what, a lot of selection, I have pretty simple needs - digital out on one pin

are there any raspberry pi type computer boards that are powered by ethernet? it doesn't need to be quite as fully featured, id rather it be cheap

e: hmm one of the usb zeros might be ok

you can get "official" PoE hats for the PI (https://www.raspberrypi.com/products/poe-hat/) and there are a lot of PoE addons for most of the arduinos.

electricity is expensive now so i've made myself a grafana dashboard that i can obsess over



i hosed up last night and fell asleep with a door open with -10C outside, oops
i also love the weewx front end for my cheap weather station and its ridiculous information overload

c itps s: rewriting the kernel of my hobby OS (which is a POS) for x86-84 instead of 32-bit x86. simplifies some poo poo, complicates some other poo poo, but it improves memory- and MMIO-bound performance significantly, and lets me ignore a bunch of legacy cruft that makes context switches more complicated and have more overhead

Pulled apart the keyboard on the Plus/4 and cleaned all the contacts in it with some contact cleaner and lube. It is now working perfectly, no need to press down hard on the keys for it to register a keystroke.

The disassembling process was made annoying by old adhesive cushion rubber strips hiding the shift lock key mechanism that requires desoldering and one of the screws.

Commodore loved those weird locking shift keys that need to be de-soldered every time you open the keyboard. They were in everything - the PET, VIC, C64, Plus/4, and multiple ones in the C128. Probably also in all their dumb failures like the C65 and Commodore 900 too.

Yeah, repairing my C128 keyboard was a complete pain in the arse.

yay my 3d printed bracket worked! only weird part was i had to get 5/8" bolts to attach the base to the quick release, i didn't bother designing a good size so it's kind of awkward.

it's technically cheaper than just buying one, but only technically. would have been less if i didn't go for stainless hardware.




edit: going to take it to go watch the sandhill cranes, my wife is a bit jittery so i'm hoping she'll get a good look at them with this.

How are you driving your hardware? I never switched to long mode on my abandoned project b/c it meant no more EZ mode bios console and disk access. I thought about switching over to the superIO serial port for the console, but wound up just shitcanning the whole thing.
