8x8x8 RGB LED Cube 30 days ago
I wasn't sure when I started this project whether the time taken to shift 512 x 3 bits into the shift registers at a speed fast enough to maintain persistence of vision via a single pin was achievable with an ATmega328. With that in mind, I split the channels so that if necessary I could shift the data through 3 pins simultaneously meaning only 512 bits needed to be shifted through each pin.

No I didn't have any problems. I guess you should check for shorts on the PCB or maybe the LEDs are faulty.
The only schematic is the one provided above. "Schematic (MAX7219 module)". The capacitors are 0.1uF 0805 and the resistors are 22K. I created a board layout from the provided schematic and then disconnected it from the schematic so I could repeat the layout 18 times and hand finish the final PCB layout.
