hi
i want to scare some cats from my garden (mainly because i have young
kids, and don't want them to catch toxoplasmosis (or whatever))
otherwise cats are fine!!!
i know there are cat ultrasonic cat scarers out there, but they are
in the 40 pounds region
i want to see if i can get an ultrasonic transducer
(Piezoelectric???) to vibrate at 18 - 22.5 kHz, but i don't want t
have to build any extra circuitry
i will then link the whole thing into homevision
any ideas
rid
