LED Matrix

15×20 matrix of LEDs, 35 mm centers.

Raspberry Pi Buster on 192.168.0.7 has an additional driver circuit board, with a 4-conductor wire to connect to the matrix.

Used rear projection film as the best thing to cover the matrix.

Having problems with bleed through between adjacent cells. Now that I can make this with 3D printing, I can make tongue-and-groove overlapping.
