To drive ignition coils is to use a 555 timer pulse generator. A 555 generates a square wave output that triggers the 2N3055. Adjusting the two potentiometers and the value of the capacitor will change the frequency of the output. Read More Source: http://www.geocities.com/mistertippy/schematics/ignition.html Thank you.

Three switchable frequencies: 100Hz, 1KHz, 10KHz 1.5V battery operated, minimum parts counting This simple circuit generates a good and stable 1V peak-to-peak square wave at 100Hz, 1KHz and 10KHz using a single 1.5V cell as power supply. An useful feature of this circuit is that frequency changes can be obtained by switching only one capacitor [...]
