Hi all. I am trying to build a shocking coil for a bird feeder and am not very experienced with circuitry. What I have in mind is using some tilt switches and a stun gun type voltage amplifier that would activate a 9 volt battery when a squirrel jumps on the feeder, closing a circuit and feeding voltage (maybe 500 volts for 2 seconds) to a coil that is in the bottom of the feeder tray. I'm assuming it wouldn't be hard to do, I just don't know where to start.. Can anyone help or give me suggestions? Thank you.
