After making the Tiny LED Matrix, the next logical step is to make them into a cube!
This project used a Qi receiver, deadbugged on the back of a coil to act as the power source. This then goes up a pair of power wires into the cube which has 6 panels and a MCU on a tiny breakout board diagonally in the centre.
A lot of very fine soldering later and a glass jar to add some protection and this turned out to be one of my favourites
