Greetings All
I would like to vary an ultrasonic mist maker like this one
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.
