This project is completely open source, from the schematics to the eventual Arduino code. The LED Cubular is made up of 6 PCB boards which come in 3 different designs. The top, the bottom and the sides. This project file is for the bottom piece; the more interesting piece.
Please see my hackaday project here; https://hackaday.io/project/164202-led-cubular-led-desktop-cube/ to follow my latest project logs.
I hope to enter this project in the The FR-1 Challenge.
