I know, progress is rather slow, but here is the next part, and basically the ground floor of the LED cube. I also added the required resistors. I didn't have a PCB so I couldn't hook it up yet, but I did decide on the PICmicro to use: the rather obscure PIC16F57 which happened to be in one of the boxes that I got for winning the Microchip Innovation competition. I need to check on it, but it has 28 pins so I'm pretty sure I can use two full PORT for outputting the data, which would reduce the requirement for quick switching between patterns. I already tried lighting one of the LED, and they burn rather brightly, and are visible from the side as well. I'm still not sure if the next layer should face up as well, but it is probably best if they do.
