I designed a cube that balances itself on a corner

The linked article is about a project that involves building a self-balancing cube that rotates around its axis in a controlled way, using smart controls and a set of three reaction wheels. The project is completely open-source, and the cube has potential uses in research and satellite technology due to its reaction wheels. The article goes into detail about the cube's mechanical design, components, and code. The cube is the only fully open-source one worldwide that achieves a balancing performance similar to that of Cubli. The article also mentions plans to add mechanical brakes to the reaction wheels for better control.
