I want to play around a little with the effects of piezo electric crystals but I'm weary of tearing up my clock's to get them(and the one I did tear up broke the crystal ;/)
Is there any easy source for these(easy means quick and cheap)? Are these things very critical in handling or, say, could I just get some of these quartz crystals and break of piece and then play around with its effects?
What I'm mainly intersted in play with are the ultrasonic effects. It doesn't have to be anything advance but just so I can have some direct experience with them and see them working in action.
Any ideas?
