50Hz square wave generator for VATs/Passkey
My weekend project: create a circuit that would create a 50Hz square wave signal to feed into the ECM/PCM on a 1990's caprice to circumvent the vehicle anti-theft system. Solution? A couple of capacitors, resistors, and a 555 timer. Result: the car runs like a dream. More to come.
