"Orbit/GAIA" LED board demo

This is a demo of my new prototype LED boards. They are 12" long and each have 48 high-intensity Nichia RGB LEDs. Daisy-chained together with a 12Mbps SPI connection, they are able to display fast-moving images, video, persistence of vision effects, etc. Current draw of each board maxes out at over 3A, but they generally consume around 1/4 of that during normal operation.

The master controller is a 66MHz Atmel AVR32UC3A which reads the video file from an SD card and sends the frames out to the LEDs. Pushbuttons on the board skip between video files and control brightness.

These were purpose built for a large installation art piece to run at a super-fast framerate (a few hundred Hz) and have a higher pixel density than any commercial product on the market.

Since they are prototypes, they were hand assembled and have a few twocked LEDs stuck in various colors.
