How it works
The system is composed of two circuits: a transmitter and a receiver. The transmitter receives audio input from a phone or computer via an aux cord. The signal passes through a low-pass filter, is amplified by an OpAmp, and then transmitted via a laser to a laser which transmits the data.
On the receiver, a solar cell converts the light from the laser into electrical signal which is amplified by an OpAmp before outputting audio through the speaker.
