I am trying to make a cicuit for my bar-b-que that with create a continuous spark between the wires with a push-to-on switch. Does it have to be ac or dc? It must plug in to the wall outlet (120V)[/b]
We've called it a stun gun, but it doesn't have to be used for that purpose!
You can use an AC-DC power adapter instead of the battery (I think the yanks call it a wall-wart), and just insert your momentary switch in one of the power leads.
