SINGLE IC FORMS SENSITIVE MODULATED LIGHT RECEIVER
The circuit uses a very inexpensive C-MOS IC that is connected to a small photodiode. Using a unique inductive feedback network, the circuit provides high sensitivity under high ambient light
conditions. It is a great circuit when you want to extend the range of an optical remote control transmitter.

Short
dc Power line pulses afford remote Control: 10/25/01 EDN Design Ideas / (added 1/05) If you face the challenge of adding a second, independently controlled light
source to an existing ceiling lamp controlled by a wall switch, you may find that stringing a second power line is impossible. First, you can replace the wall switch by the circuit in Figure
1. Pushing the on switch S1 or S2 for approximately 1 sec inserts the 12V zener diodes D1 or D2 in series with the ... ... |

Universal Infrared Controller for a PC: This simple circuit allows you to record any Infrared remote control signal on your
PC, and then play it back. This is particularly useful if you want to control appliances such as TVs, VCRs, CDs etc. from your computer. The device simply connects to the parallel port of your
PC. You can also use this circuit to analyze the waveform from any Infrared remote control. This circuit was originally published in Electronics Australia, September1998 (Electronic circuit
