    Hi,

    Can anyone help point me to a circuit (or kit) that uses a STANDARD IR remote
    control (like one of those $9 replacement ones) and gives me the ability to
    "see" which button was pushed.

    I,m looking to have 12 (or more) lines, one of which switches WHILE the button
    is being pushed, and does NOT latch.

    Thanks, John

    I don't know of anything that matches what you describe.

    You can get a box that will turn button pushes into RS-232 characters.

    I think that gives you a sequence of repeated characters if you
    hold the button down.

    You can get the raw IR receiver modules. They output a TTL/CMOS signal,
    but that's a seqence of pulses with different codes for each button.
    Several vendors make them. Their data sheets may have enough info
    to build your own decoder with a low end uP.

    Two solutions, each at extremes of cost/complexity. 1) a PIC or BASICSTAMP
    (IR decoder goes into an input, etc, etc.). 2) a PC with an IR decoder
    running LIRC (http://www.lirc.org) Linux Infrared Remote Controller (also
    Windows version).
