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 . . . [Circuit by David Johnson P.E., 06/04/00]

Modification of Lazer Tag Equipment - I added a "fast-fire" circuit to get around the annoying delay that prevents you from firing again immediately. It used the target LED contact on the trigger switch to reset the pulse generator. That way, normally when you fire the sound goes on for its normal duration (we banned any mod that would turn off the sound or always. . . [John DuBois designer]

Optical Module Development Platform 2.5 GBPS Transmitter with Digital Diagnostics - AN-654 Analog Devices App Note - The SFP Digital Diagnostics Development Board is a platform designed to enable optical module designers to develop SFP and SFF compliant transceivers with digital diagnostics. . . .

Provides Laser-Diode Control - 09/19/02 EDN Design Idea Laser diodes are sensitive to ESD, rapid turn-on currents, and overvoltage conditions. To address those problems, the simple laser-diode controller in Figure 1 has several functions. The first part of the circuit comprises an 8. 2V . . . [by Michael Fisch, Agere Systems, Longmont, CO]

RS-232 Laser Transceiver - . . .

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. . . . [shaunwilson19 AT yahoo.com]
