Circuits Designed by Dave Johnson, P.E. :
  • Light/Dark Activated Motion Detector -  This circuit can sound an alarm when the shadow of a hand or arm moves over  two small photo diodes . . . [Circuit by Dave Johnson P.E.,  08/21/05] 

  • 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 Dave Johnson P.E.,  06/04/00]

Long Range IR Transmitter -  This Long range Infrared transmitter can emit pulsed IR rays up to 10 meters. This IR transmitter is ideal to use in Infrared receivers using Phototransistor or Photodiode as IR sensor. The circuit is a simple Astable Multivibrator using IC NE555. Resistors R1, R2 and capacitor C1 fix the output frequency to 1 kHz. T1 is the. . .  [Circuit Posted by D Mohankumar]

 

Long-Range IR Transmitter -  Most of the IR remotes work reliably within a range of 5 metres. The circuit complexity increases if you design the IR transmitter for reliable operation over a longer range, say, 10 metres. To double the range from 5 metres to 10 metres, you need to increase the transmitted power four times. . . .  [© EFY Enterprises Pvt. Ltd. All rights reserved.]
