    Post IR Sensor question...

    I just purchased a Keyspan digital remote. I was hoping that someone could tell me how I could add a remote IR sensor for it, so I don't need to have the bulky receiver in view. In the IR "window" there is an LED looking thing and a small black thing I think may be the receiver. I'm not too sure what they are, and which is the sensor, but could I unsolder them, add a length of Cat 5 or something where they were and resolder the devices at the ends of the wire??

    Otherwise, does someone know of an IR repeater (sensor on one end, stick-on emmitter on the other end)?
    Any help would be greatly appreciated.

    Let me get this right... You want to extend the length of the IR sensor. Cat 5 will work fine for that. Are you using IRman? If you are there should be 3 wires going to the sensor (small black rectangle), just unsolder them and add the length of Cat 5 that you want. I was able to extend mine about 7 feet without any problems using a telephone cord. Personally I ditched the casing because like you I thought it was too bulky.

    LIRC has excellent info on creating IR sensors for serial and parallel ports. With some free samples from Siemens and leftover parts I created a serial receiver for my Linux box. If I had bought the couple parts at Radio Shack it probably would have cost me under $5.

    It might be more of a project than you were looking at, but it would save you from tearing your working receiver apart.

    To calrify, I am using the USB IR receiver included with the Keyspan remote as seen here:
    http://www.keyspan.com/products/usb/remote/

    So what I was most concerned about is that if I de-solder the IR sensor that is there, do I need to worry about any interference in the extension?

    Thanks.

    I really wouldn't be worried about interference because of extending it. The first time around I actually had a bunch of cheap 22 AWG wire laying around and it worked fine. If you are using something that is somewhat shielded you should have no worries. Try it, if anything doesn't work right then you can always go back to the original wiring.

    when I made my second IRMan for the car I extended the receiver about 1.2mtrs from the circuit board with three wires cut off an old IDE cable. works perfect... check it on my website.....
    Project - GAME OVER :(
