I’ve been following the development of the LED lightcube for quite a while. I was in my local Fry’s earlier tonight when I noticed they were selling this 4x4x4 cube for $99. Initially I wasn’t going to buy it, but after careful consideration I thought that the saving in labo[u]r costs were probably worth it.
64 RGB LEDS with a PIC18F driving 4 AHC574 (Edge Triggered Flip Flops) to signal all the LEDs.
Almost certainly hackable…
…will update when more information is available.
