An independently developed motor made with a 3D printer, worked on from 2022 to 2023.

I presented it at Science Castle, MITOU Junior, and Maker Faire Tokyo.

I built a circuit and reached the point where the motor could rotate using forced commutation. Someday, I want to write proper control software and make it run well.

All CAD data and related materials are available on GitHub.
