[bouLED] Done with the PCBs

We finished the PCB design this week (they are currently being reviewed by Alexis). The voltage regulator placed in the center of the triangular PCB had a few constraints, but routing the LEDs was simple enough so I could use the autorouting and just make a few modifications to it, like shortening the VCC paths and widening these traces.

We placed a few mounting holes, to screw the triangles on folded metal sheets keeping the icosahedron together.

By the time the PCBs are delivered, we’ll write as much software as possible. We’ll use our devkit to play with the ESP32 and some SD card reader, and, most important, we’ll write the display algorithm (we fortunately happen to have a simulation to help us).
