Infrared Viewer -  Here I made an infrared viewer  (night vision scope) from mostly crap out of the trash.  I did have to buy the main component, the image intensifier tube, because I think it's pretty unlikely that I'll come across one in the dumper.   __ Designed by Greg Miller

Infrared/Ultrasonic Beacon -  The whole transfer-protocole may be omitted, if the receiver-circuit is changed at the D/A-converter stage.  Replace the 4-bit converter by a well-designed 8-bit device.  This increases dramatically the positionning speed.  But for didactical purpose the 4-bit converter is a marvelous base to teach serial information transfe __ Designed by Boulette's Robotics page

Infrareds for remote control -  Infrared based electronic circuit diagrams / circuit schematics __ Designed by Peter Jakab

IR Proximity Sensor -  It is the same principle in ALL Infra-Red proximity sensors.  The basic idea is to send infra red light through IR-LEDs, which is then reflected by any object in front of the sensor.  Then all you have to do is to pick-up the reflected IR light.  For detecting the reflected IR light, we are going to use a very original technique: we are going to use another IR-LED, to detect the IR light that was emitted from another led of the exact same type!This is an electrical property of Light Emitting Diodes  (LEDs) which is the fact that a led Produce a voltage difference across its leads when it is subjected to light.  As if it was a photo-cell, but with much lower output current.
