HI,
This is my first post. hopefully someone can help me out. I have created a device to melt the verdigris on Steinway piano hammer flanges. Basically it is 12 volts, 2 Amps AC running through a of pair of insulated tweezers. Squeeze the tweezers together on a metal piano center pin and a short is created. The heat generated melts the verdigris in a couple of seconds. It works fine but I would like to a have a beeper or buzzer sound when the temporary short circuit is created. For safety's sake.
