Sorry...Dunno.. All that came to mind was "Clap on...Clap off" :P D from BC
Sure,
1) is it strictly frequency and not amplitude dependant? 2) what type of motor? 3) what is the application? Regards Ken
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! Rich
So the louder and higher the lady shrieks the faster the motor turns. Sounds vaguely familiar, any ideas on how that might be applied? Ken

--- I like it! E1 E2 / / . [MIC]---[ZCD]---[ONE-SHOT]---[DRIVER]---[STEPPER]
The one-shot is non-retriggerable with a fixed-width output.
High Freq: _ _ _ _ _ _ E1_| | | | | | | | | | | | ___ |_| |_| |_| |_| |_| |_|

How about a carbon mike in series with a motor?
VLV
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.
Ask my dentist.

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
done.

"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! Thanks Ken
They have a cure for clap, in the US.

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