Circuits Designed by Dave Johnson, P.E. :

MICRO POWER 40KHz BURST LASER DIODE DRIVER
Some laser tag or simulated combat games can use this circuit to send short bursts of modulated laser light at the opponent's vest, equipped with a matching light receiver. The circuit operates from three 1.5v cells (4.5v) that should provide enough energy for about 200,000 shots.

MODULATED LASER DIODE TESTER
This circuit can either be used to test laser diodes or as a general purpose modulated light source. The circuit has an adjustable diode threshold current and an adjustable modulation frequency. The frequency can be adjusted from below 30KHz to above 50MHz. It is powered from a 9v battery.

Modulated Laser Light Source - do a lot of optical electronics work. Often I need to test a modulated light detector hobby circuit at a particular frequency. The device below has come in handy many times. I can adjust the frequency of the modulated infrared laser….

RS-232 Laser Transceiver - 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. ….(electronic circuit added 7/03)
