Controllers

The controller boards were bought from [[1]]. They use an atmega328 to control 3 tlc5940's which provide PWM signals for 16 channels. To control a led board of 16x8 leds the PWM signals are multiplexed. The input for the boards it a 1M baud serial signal. The boards can be linked together up to probably 8 boards in a chain.

Led panels

The panels are made the old fashioned way with single rgb leds (common anode). When we started led strings were still hard to get and expensive. Now it would be much easier and probably cost as much to make the panels from led strings.
