Cube motherboard
Cube motherboard is an open source ESP32 PCB design by willem-pennings: a 4-layer, 95 × 95 mm board with 42 components (21 distinct parts). It is built around the Escon_24/2, 356-EP32S3DVKTC1N8R8, 926-LM2596SX-5.0NOPB, 998-MIC5225-1.8YM5TR and more. Filed under robotics & motion.
A cube that balances itself in a corner or edge using reaction wheels
This repository contains all design, documentation, configuration and other files related to the balancing cube that I have designed and built. Mechanical parts are designed in Fusion 360. Circuit boards are designed in KiCad 7. Code has been written using Arduino IDE. Motor drivers are commissioned and tuned using Escon Studio. Motors and motor controllers are available from Maxon. Circuit boards and custom mechanical parts can be ordered from PCBWay, for example.
