AVR Laser Audio Transmitter

05/13/2009 Category: Audio, AVR, Transmitter


Laser Audio Transmitter is final project from student. In This project Jehhal Liu and Daniel Zuo try to build a device that able to transmits an audio signal using a laser beam.

They created a mono-axial transmitter/receiver setup that converts an analog audio signal, via a standard 3.5mm jack, and transmits it via a laser to a receiver, which converts the signal back into audio. The receiver can be rotated within its horizontal plane, and uses a servo motor controlled by a microcontroller to automatically align it with the receiver. The end result is a wireless audio signal that cannot be “overheard” by other devices.
