I would for my own personal reasons like to bypass a ~32khz quartz crystal with a transistor(s) powered by a microcontroller generating 20-40khz. I don't know how the crystal works so I'm not sure how to bypass it. Could I just hook the collector and emmitter of the transistor to where the legs of the crystal were, using a multimeter to determine the direction of the electricity and drive it with the microcontroller, or is it more complicated than that? This is a personal no-reason experiment that I have been wanting to do for a while and am finally getting around to. I'm not really worried about burning anything up, the circuit with the crystal only cost $2.50 and the microcontrollers are $1 each so if it goes up in smoke for some reason I haven't really lost anything.
