Wiring a switch to a TV remote

  1. My brother is disabled and wants to have a simple switch
    (http://www.tashinc.com/catalog/s_soft_yet_strong.html) control the
    favorites button on his Motorola digital cable box. I read on an
    email list that it is possible to solder the jack from the switch to
    the remote control so that it activates the favorites button so that
    he can change channels...could anyone help describe the specifics or
    any other ideas?

    We've tried the scanning switches (Relax from Tash) and a computer
    driven solution isn't feasible (he doesn't want the computer near his
    bed).

    Thanks so much in advance -

    Sarah

    The basic idea is to open the remote and connect a jack to the printed circuit
    board on the back of the remote's keyboard. The jack would connect to the two
    traces that are associated with the "Favorites" button. Your switch would then
    be connected to a plug that matches the jack used on the remote. Pressing the
    switch would then be the equivalent of pressing the "Favorites" button in the
    remote.

    I can't be more specific because I have no idea which remote you have - Motorola
    provides a number of different controllers for different cable boxes.
