This project is a proof-of-concept device that transmits an audio signal using a laser beam, while removing the need for the user to align the beam themselves.
A mono-axial transmitter/receiver setup is created 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 micro-controller to automatically align it with the receiver. The end result is a wireless audio signal that cannot be “overheard”by other devices. Entire project can be divided into 2 sections:
- audio transmission via hardware
- alignment control via software
