Infrared Remote Extender Circuit
designed
by David Johnson, P.E. |
This electronic hobby
circuit is designed
to be placed directly in front of a standard TV or VCR remote.
|
|
The exiting
light pulses produced by the electronic circuit match the pulses from the remote but are
about 10 times more powerful. Using the device, the remote can operate a TV or VCR over
three times the normal distance. I you wish, you could add two more infrared LEDs.
The distance would then extended by a factor of 4 times. I suggest using a Vishay
TSFF5200 infrared LED to get the best results. |
