Arduino in the same vein. There’s a great “30 Days Lost in Space” tutorial set, but even to play around with by yourself for cheap, you can get an off brand (the hardware is open source!) Arduino Mega for 20 bucks. All sorts of cool programming and electronics fun.
would a raspberry pi count? i’ve been self-hosting a nextcloud instance and my RSS feed for a while now and i’ve really been enjoying it

Ditto on the Arduino. I built a pickup winder for electric guitar, and it’s more than made up for its price in entertainment alone.
