The DodcaRGB is a 12-sided Dodecahedron model created using custom-made LED pentagon-shaped PCBs. All 312 LEDs are addressable RGB (WS-2812) and can be controlled from a standard microcontroller (ESP32, RP2040, Arduino, etc).
The LED points were mapped to 3D space using a simulator written in Processing.
The firmware allows the animation of these points.
There’s enough space inside of the model to hold a standard USB battery pack and microcontroller, making it fully portable.
This project was previewed at the 2023 CCC Camp in Germany, with over 6000 attendees, and some prototype kits were sold.
More instructions and info will be posted here soon, along with source code.
