Greetings All
I would like to vary an ultrasonic mist maker like this one
http://www.physlink.com//estore/cart/UltrasonicMistMaker.cfm
using my audio sound card.
Example:
I want to produce complex waves using my sound card 4000Hz square wave
combined with some 1000 hz sine waves etc.. I would like to be able
to vibrate the ultrasonic mist maker transducer at this rate. Is this
possible?
I can create the audio waves easily but I'm not sure how to drive/control
the vibration of the ultrasonic mist maker using the signal coming from
my sound card. Does anyone have any recommendations? I'm trying to keep
this as cheap as possible and use a ultrasonic transducer off the shelf.
