I quite like to dabble in technologies I don‘t get to use at work - mainly embedded systems.
Using a MAKERFABS ESP32-TOUCH-CAMERA development board, I ported and extended some code by another user to work with the constraints of the ESP32 environment. This project was a 2D simulation of the positions of the planets in the solar system at a configurable time.See on GitHub →

Data has never tasted so sweet.See on GitHub →
