universal remote control...?

    Hi Stan, in a nuts&volts magazine I've found a program that decodes de
    12bit SIRC (Sony IR Control), the limiting thing here is that you need
    to buy a sony universal remote or use a original one. You only need an
    available stamp pin and a Sharp GP1U52X available from RadioShak
    (#276-137) or a Panasonic PNA4602M that comes with the stamp kit, both
    works well.

    You might have to use two stamps cause this app needs all speed from the
    processor, so time is important (one for the boe-bot and another to the
    remote), but you can mix the program in one so you'll have one processor
    on your boe, one last thing, this app consumes a lot of ram on the BS2
    since it have not enough speed to process the bit before the next one
    arrives, so you'll have to keep them all in separated word sized
    variables, if you want to solve this use a BS2SX and you'll find no
    problems cause it haves more speed and therefore you would use only 1
    word sized variable instead of 12!!.

    You can modify the code so you can store numbers in EPPROM and configure
    the movement of your boe!! Pretty cool huh!!

    I've attached the program!!
    If you want more info, please contact me through the list. (my English
    is not good at all, I'm from Venezuela je je [noparse]:)[/noparse] )

    I am reasonably new to robotics, electronics, and stuff. I did build
    one basic robot with a BS2 that worked reasonably well. I am now
    trying to build a robot with a BS2 that I want to be able to remote
    control. I initially planned to use the 418 mHz transmitter keychain
    remote thing but it only has five buttons and I want quite a few
    more than that. I was wondering if anyone has other suggestions?

    With five buttons and enough dexterity, you can actually get 31 commands
    as the keychain transmitter sends the bits in parallel. I created a
    Halloween display with a Quadravox unit that was activated by the
    keychain remote. I used the center button as a "shift" function giving
    me eight choices.

    Honestly, it's tough to push more than two buttons at a time, but even
    at that, you can get these combinations:

    (A)
    (D)(E)(B)
    (C)

    A
    B
    C
    D
    E

    AB
    AC
    AD
    AE

    BC
    BD
    BE

    CD

    You have quite a few options.

    1. As Jon mentioned, you can press combinations of buttons on the Parallax
    keychain type transmitter.
    2. Construct your own RF transmitter/receiver circuits using the Holtek series
    8-bit encoder/decoder ICs. You have 8-bits latching + 1 momentary.
    3. Use infrared. Parallax has several app-notes for decoding Sony IR
    transmitters.
    4. Use a dedicated Sony decoder IC.

    We carry the Holtek 4-bit & 8-bit encoder/decoder ICs with several RF
    transmitter
    receiver modules, custom 8-pin (address learning) 4-bit decoder ICs for the
    4-bit
    encoder series, and two versions of Sony IR decoder ICs.

    Take a peek at our remote control store for many different options.
    http://www.rentron.com/PicBasic/RemoteControl.htm

    Our IR-D15A IC provides 14 "momentary" outputs that remain ON while holding the
    transmitter button down, and 1 "latching" output that is toggled ON & OFF when
    depressing and releasing the transmitters power or ON / OFF button.
