You, too, can build this ESP32 3D-printed solar system model, and yes, it spins
The Meridian Orrery is a DIY solar system model that utilizes an ESP32 and 3D-printed components. It features a unique calibration process that allows it to accurately display the positions of planets and includes a miniature moon orbiting Earth. This project combines technology and creativity, making it an engaging way to represent celestial bodies in a home setting.
- ▪The Meridian Orrery uses an ESP32C3 and DS3231 RTC to calculate planet positions offline after a one-time calibration.
- ▪It features a clever gear ratio that allows a tiny moon to orbit Earth accurately as the planets align nightly.
- ▪The project is designed to be easy to build, requiring only basic components like motors, magnets, and a 3D printer.
