Audioguru once mentioned this circut, which wd generate a variable square wave output to emulate the negative ignition wire of a car engine, hence making testing of RPM meters and shift lights much easier.
Can anybody point me in the direction of a good circuit that would generate the optimum frequencies that could be generated by a car?
I actually came accross one here.. is this allright?

Thanks!
