    I will be the first to admit that I am a bit of nerd in loving to know
    how things work. I also love music so I know much of how the music
    world works. I was sitting at the computer with guitar in hand looking
    up when I noticed some interference. I know that a guitar pickup works
    by a coil of copper wire wound around a powerful magnet to detect
    changes in magnetic feilds, and that speakers work almost in reverse;
    creating fields by a copper wire wound around a magnet, only this time
    an alternating current in the wire vibrates the magnet attatched to a
    diaphragm. This is when my amazing idea hit, the speakers in my ipod
    ear buds create fields, and my guitar detects them. So I decideed to
    try a little experiment and set my earbuds on my guitar pickups, turned
    the amp up, and hit play. Instantly "Caught Up In You" was blasting
    throughout my bedroom with more than decent sound quality.

    That was just one I thought I'd have to share with the rest of you

    Try this. Put a TV/VCR/DVD <whatever> remote control near your pickups, hit
    a button and you'll be able to listen to the data code pulses being sent to
    the infrared diode.

    I remember when the first IBM computers came out in the early '60s the
    tech guy who was showing off the computer put a AM radio on top of the
    box. Ran a little program and a tune came out of the radio. I think it
    was Daisy but that might be HAL.

    Try putting a vibrator up to your pickups.

    (Actually, any motorized device will do - like an electric drill a la
    Van Halen's "Pound Cake" - but a vibrator is probably the most
    interesting piece of hardware you can use.)

    Playing my Strat with a cell phone in my front pocket. Phone rings.
    Neighborhood knows.

    their pocket......

    I actually hadn't thought about this since I saw it in the '60s.
    I just tried it myself in an eMac that I had on the bench. It was quite
    cool, on start up you could hear the switching power supply start up. I
    wonder if you had an AM receiver that tuned much higher frequencies you
    would hear more interesting stuff. I do have a shortwave receiver but
    it's down. I'm going to try it inside near the motherboard.

    On the vibrator as posted below. Have you tried that while watching TV.
    You get some interesting distortion effects esp if the vibrator has a
    variable control. Hey, Newton stuck things in his eyes.

    When I was in high school we had an IBM 360 mainframe ( took up the whole
    room ) with a CPU the size of a refrigerator. We would place an AM radio on
    top of the CPU and load a FORTRAN program deck, which when executed would
    play *Flight of the Bumble Bee*

    We also kept a vase with a flower in on top of the CPU to remind us the damn
    thing was a bloomin' idiot <g>

    www.scitoys.com. There are plans on that site somewhere for modifying a
    cheap fm radio into high frequency am reciver for listening to aircraft
    signals. I myself haven't tried it.
