ETH Zürich’s Cubli balanced on a corner years ago, and the follow-up work stayed largely closed source. Pennings reverse engineered it from scratch and published everything. Three reaction wheels spin up to 6,000 rpm, driven by Maxon motors and an ESP32-S3 on a custom board. The labs published papers. One hobbyist published the whole thing.
