512 LED cube (again) - Hack a Day

We’ve seen LED cubes before, but [nick] upped the ante with his 8x8x8 LED cube that uses only three pins on his microcontroller.

Previous LED cubes we’ve covered drove the LEDs with shift registers and latches, but [nick] used STP16CP LED sink drivers to reduce the component count. The STP16CP can control 16 LEDs each, can be cascaded off of each other, and can operate up to 30Mhz. With a component like this, you’re limited by your microcontroller and not your patience or soldering skills.

While he was waiting for his LEDs to arrive in the mail, [nick] decided he would get a head start on the animation code by plunging into MATLAB. After getting an idea of what would look good on the cube, [nick] wrote the code on his PC to send commands to the arduino controlling the sink drivers. To wrap up the project, [nick] put the cube on a very attractive wooden box stuffed with the electronics. All tolled, a very efficient and elegant build.
