Really cool thanks for the link. I have experimented a lot with the OOK modulation and open-air laser wireless communication. It can be done just using visible light LEDs as detectors and small laser diodes, they just need to be of the same color. A free-space optical link can be built in minutes, see https://github.com/gioblu/PJON/tree/master/src/strategies/AnalogSampling https://github.com/gioblu/PJON/tree/master/src/strategies/An...
