  3. Sure,
    1) is it strictly frequency and not amplitude dependant?
    2) what type of motor?
    3) what is the application?
  4. Take a microphone and connect it to a motor. If you yell loud enough,
    the motor will work.

    Zero-crossing detector and stepper motor?

    Good Luck!
  6. So the louder and higher the lady shrieks the
    faster the motor turns. Sounds vaguely familiar,
    any ideas on how that might be applied?

    The one-shot is non-retriggerable with a fixed-width output.

  9. How about a carbon mike in series with a motor?

    Sure, why not?

    Small enough motor or big enough mike and it should work.

    Only thing that might be a little iffy would be driving the mike
    hard enough to modulate, say, a 1/4HP motor...

    Big power amp and loudspeaker duck-taped to the mike?

    On second thought, if the mike's housing had a quartz window in it
    it could be used for a communications spotlight.

    It's easier said than done.
    .... and if you don't believe it, try proving that it's easier done than
    said, and you'll see that it's easier said that `it's easier done than
    said' than it is done, which really proves that it's easier said than
  12. "Sex", maybe, that's something other people do,
    right, anyway, I saw some unusual attactments
    for reciprocating saws that was vaguely familiar.
    Voice activated motor speed control, that would
    be a great stocking stuffer for the wife this Xmas!

  13. They have a cure for clap, in the US.

    Service to my country? Been there, Done that, and I've got my DD214 to
    prove it.

  14. Does anyone still manufacture carbon microphones? I haven't seen a
    new one in 20 years.
