I built the circuit shown in the link with 240v
It did not work (produceing no spark), as I believe my capacitor was much too low of a value (around 5nf). Anyway, The capacitor was made from tin-foil like the one below
I then made another capacitor in the same way, though forgot to include the space at the end between the tinfoil. Because of this, the capacitor short circuited. This caused the light dimmer to go up in a puff of smoke. I know it was stupid and i'm done with that circuit now, but nonetheless I am still wondering why I got no spark. Even as the circuit had virtually no capacitance, the ignition coil produced no spark. This makes me think maybe the fault in the original circuit was not the capacitor? Also, does anyone know why this caused the light dimmer to die?
