This we figured out the characteristics of the cube. It will be a 12x12x12 cube and at each time, only the leds in one “floor” (a 12×12 board) will be on. This means that a led will be on 1/12 of the time so it has to have enough power to make use of persistence of vision. This also means that we can have about “only” 400 cables. We also finished the presentation for tomorrow and studied it.
