    I would like to use my TV remote with the stamp BS2. DO I need an
    IRda device. Has anyone done this? Thanks

    I did an article about using a remote with the BOEBot for Elektor awhile
    back on behalf of Parallax. I thought it was available on the Parallax
    site -- but I don't see it with a casual glance. Actually, if you look at
    http://www.stampsinclass.com/Robotics.asp they mention it, but I don't know
    where it is online.

    The idea is to use PULSIN very rapidly to read all the pulses in the IR
    packet and then decode them. The Stamp isn't fast enough to read and decode
    at the same time. The problem with this is that the PULSINs have to timeout
    before you can realize no one is sending data. So you have to design your
    interface to require constant IR commands. My bot ran if you pressed and
    held "2", but if you wanted to make it where "2" starts and "5" stops that
    is a problem. It will be jerky as it times out waiting for commands. Of
    course if you use a PAK-VIII like the BOEBot in our Stamp Project of the
    month does (http://www.al-williams.com/awce/som.htm) you might get around
    this since the Stamp then doesn't constantly control the motors.

    I have done this with a sony remote, however the bs2 is a little too slow to
    do this. The results are sometimes random, and it may not work with all
    remotes. My hard drive crashed a while back and I lost the code. If you
    can find a way to make it run better it would be perfectly feasible. I
    wrote some code for a pic f84 in PBC and it works great. I can pass this on
    to you if you like. The only hardware I needed in both cases was a 38khz IR
    module.

    Hi,

    Yes, I have done it. All I used was the Sharp GPU52x(something like
    that) IR Detector easily found at Radio Shack. It will detect just
    about any infrared remote. If you want simple on/off processing this
    will work good with your TV remote or any other infrared remote. If
    you want to distinguish between the buttons you are going to have to
    measure the pulses, use a decoder IC, or do something serially.
    There are many infrared kits that will get you started in addition to
    the site mentioned in the previous reply.

    Have fun!

    Ed,

    I'm interested in the code, please email me the code at
