Guys:
A while back RS used to sell a slick IR repeater so that it was easy to transmit signals to components located behind closed doors.
RS doesn't have this anymore and I am in need of something similar.
Any ideas. I've done a serach on the Web but so far I am coming up empty. _________________ Paul |

Several years ago, I bought a pair of devices (IR to RF and RF to IR) for that. I think they were the Powermid, that I just found in this ad.

but I think it was significantly less than the $50 that site sells the pair for. I didn't shop around today. That was the first google hit. |

I built my own IR repeater using PIC microcontroller, although it might be a bit complicated for what you want to do. Here's what I did:

There are fundamentally two ways to remotely control equipment behind closed doors, wired and wireless. The wireless systems are so cheaply built and so constrained by FCC requirements that they are doomed to perform marginally. If you want the challenge of limited range and the never-ending threat of interference from electrical noise sources, try the wireless solution. But if you want solid, dependable performance, check out the variety of devices at http://www.hometech.com. These systems employ a sensitive receiver to pickup and amplify the IR signal, and a small stick-on infrared emitter to couple it to the controlled equipment. The link from receiver to emitter can be either a spare pair of wires, if you have it, or you can multiplex the IR signal over an RF cable. There is some excellent tutorial info at the site, and my research indicates their prices are about as good as anywhere.
