Upgrades: Dot Matrix Cube

Following the arduino dot matrix prototype, I am constructing a Cube of Led Panels to be form a handheld interactive art platform.

The new setup has 3 ESP32s and 6 panels, each with 256 LEDs. Powered by an RC car battery, accelerometer-guided simulations and interactions should be possible for multiple hours (depending on brightness and particle count).

As my first soldering experience, this turned out much more satisfying than I expected. Each ESP32 has the same power and data connections to its 2 daisy-chained Dot Matrix displays. There is one master controller and 2 draw-only controllers, enabling much higher draw speeds than a single ESP32 could achieve. To cross-communicate, the ESP32s have multiple sync cables to manage frame time, draw requests, and other data.
