New Interactive RGB LED modules

Website: www.goodcurrent.net These are my new boards. I hand-built 10 of them and strung them together one after the other. The work very similar to the old boards with a slight difference of the sensor circuit. It used to be a simple amplifier, but now the output from the photodiodes is fed through a differential amplifer. Three of the four opamps of the quad opamp chip are used. Two opamps are used as simple buffers, and the last is a differential amp. One opamp is for the sensor outputs and one to buffe
