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.
