Hi 
Unless you are using a Model T coil which has its own vibrator/ interrupter 
built in...

If it is simplicity you are after the light dimmer (ceiling fan speed control, 
it is made for inductive load)/capacitor is as simple as it gets. 
See:http://wiki.4hv.org/index.php/Ignition_Coil for a schematic.
