I am wanting to build a wire tracer. I need to generate a 20v rms square wave at 20khz. Is this practical with 3 9v batts? I realize I need a lot more voltage supply then what 3 9v batts will supply, is there a simple DC voltage boosting circuit I can build that is efficient and small? The output dosnt need to supply any real current since it just needs to apply the voltage wave form across a wire and ground and an inductive light tester indicates it is the correct wire(the tester emits a light when you put it near the wire with the tracer signal.
I want to use an astable 555 timer and amplify the output to 20vrms(which seems harder then I first thought).
