The new IR-Repeater solder guide makes it possible for you to accommodate your HiFi equipment and the TV receiver in a cupboard or even remotely control a PC, Media Player, etc. with a remote control unit from another room.
Infrared signals from a remote control do not transmit through a wall or in a HiFi cabinet, so this IR extender receives and modulate the IR signals and passes them via a cable to two IR transmitter diodes which are transmitting the signal to the respective HiFi equipment, HTPC, Media Player or PC with IR receiver.
So one can install a television for example in the living room and control the receiver in a cabinet or control the devices with an infrared remote in another room.
The electronic parts for soldering the new IR extension are available as an inexpensive kit at the OCinside.de Fanshop.
So heat your soldering iron up and enjoy reading the infrared repeater solder guide and build one by yourself.
