Disco PCB... My first PCB design! Used through holes and generous spacing to make it as easy as possible to solder. I give it 50/50 chance of working. Check back in 2 weeks.

My #rasberrypi system monitor service on Ubuntu. The fan is triggered by the CPU temp. Uses a transistor to shut off power when during shutdown. Code in comments.

Awesome!
Inspired by @leerehwinkel.bsky.social to try solid core wires for breadboarding. Basically built a baby grand piano.
