Massive wall-mounted skull lights up workshop under Arduino control
While you may or may not want a gigantic backlit skull haunting the wall of your workshop, this was perfect for Jay and Jamie of the “Wicked Makers” YouTube channel.
Their device is cut out of two 30” squares of plywood with a CNC router. This forms a base layer that holds everything off the wall, while an outer layer provides a nice circuit/skull texture.
They affixed WS2812B LED strips to the base layer, controlled by an Arduino Micro. These strips shine off the wall for a glow through the edges, along with circuit board style cutouts inside the skull, diffused using wax paper.
Arduino code and the circuit diagram are found in the project’s write-up if you’d like to construct your own!
