Meridian Orrery — A 3D Printed Solar System on Your Desk Powered by ESP32C3 🌍🪐 Introduction What if you could print an entire solar system on your desk? The Meridian Orrery makes this possible with just an ESP32C3, a 3D printer, and some clever engineering . This open-source project puts all 8 planets (plus Earth's moon) in motion—calculating their positions locally, with no internet required. What Is It? The Meridian Orrery is a fully functional orrery — a mechanical model of the solar system — built entirely with 3D-printed parts and an ESP32C3 microcontroller. Each planet orbits the sun at accurate relative speeds, and Earth's moon actually orbits Earth too. The magic? It's all computed offline directly on the ESP32C3 using astronomical algorithms. No NASA API, no Wi-Fi, no external data sources.…
