Hi everyone!
I built a circuit to generate controllable sparks. I want to produce spark between a probe and a metalic surface. It sould have audible sound.
I have used a 12V motorcylce Battery and an ignition coil of a car. A microcontroller produces some pulses to the base of a 2N3055 transistor. 2N3055 turn on an off the primary of the coil and the desirable sound is produced between the probe and the surface.
BUT, MY PROBLEM IS:
The volume of this circuit is very much. I want to reduce the dimension of my circuit but the battery and the coil is very huge.
Is there any other circuit can solve my problem?
