    Fiber optic for LCD IR extension?

    As I was contemplating unsoldering my IR receiver from the PCB board, resoldering wires there, resoldering wires to the IR receiver, I tripped upon an idea. Would it be possible to avoid all that and just fix one end of a fiber optic wire to the IR receiver and fix the other somewhere on my dash?

    1) Would this work?
    2) Would it be just as easy to use as the IR receiver would, or would I have to point the remote directly down the “pipe”.
    3) Would I have to use the remote within an inch or two of the “pipe” or would it be more forgiving than that?

    the focus is far too narrow for what your trying to do. You would have to place the transmitter directly on the end of the optic fo it to even have a hope of working, even then I doubt it would work all that well as I think you would loose too much of the signal in the joint to the reciver. Your best bet I think would be to re-site the reciver or loop of the original into maybe a 3.5 jack on the case then you could add another reciver and still be able to unplug the unit without taking the car apart.

    Fairly certain it would work if you could get the inferred source to enter the fiber.

    I think it might be easier to just relocate the sensor to a more desirable location pending it is possible with your application.

    I had a toslink cable around so I gave it a try. It worked like a charm. Good enough to forgo the soldering in favor of fiber optic. You do have to point the remote right into the “pipe” from a few inches away but that is fine as one rarely needs to access the menus.

    Here are some pictures of what I did.

    It is a little hard to see but what I did is bend the IR sensor back a little so that a toslink cable taped flat on the back of the PCB board would point directly into it. The toslink end had a flat spot there so everything mated up nicely.

    More images of the frame if you are curious. I’ll make a full install post once I am done.

    Just get the PAC IR-X. It's cheap and works great.

    <shrug> ~$30 for the IR-X v.s. $4 for the toslink cable.
