I made my own firmware for the little AI assistant esp32s3 AI balls you can buy from Ali Express. https://www.aliexpress.com/item/1005008627679270.html

Made a version of Infocom adventure frotz player to work with voice control on the AI ball so I can play Planetfall using voice control.

Made a toast alerter for Linux terminal command line.

Made a thing to alert you when someone signs in to a Linux server.
