LED Cube Matrix 4x4x4 with Sound EQ device

So this is what i have been working on of late: http://www.youtube.com/watch?v=QfCOr0YetK0&feature=channel_video_title

Basic design of the cube: columns of the pins connected via the anodes, layers connected togeather via the cathodes. This allows us to light up the cube one layer at a time and if we do it fast enough it looks as if the entire cube is lit up.

Because i made this to go with the arduino, i had a limited number of i/o pins so i opted for the use of shift registers. This allowed my to transmit data about the cube in a serial fashion and read it out in parallel. the image above give a rough working of it. Its fairly similar to others out there (other than the shift registers)

Next post: code used and the sound equaliser
