MAKE: Blog: RS-232 Laser transceiver

RS-232 Laser transceiver

Laser10
Laser transmitter from Electronics Australia - "Laser based projects used to be expensive, until the development of solid state lasers. This project is designed for the entry level laser experimenter. The circuit allows any two computers with serial (RS-232) communication capability to communicate over 200 meters using a laser beam. A low cost transmitter only circuit is also presented here for use in one way communication and other laser based projects." - Link.
