    I have built a combustion cannon and for safty reasons I want to run a long electrical wire from it to a firing box. I need someway to get enough voltage that I can have a spark jump from one bolt to another inside the chamber. I think I can do it with two car batteries and a motorcycle coil but Im not sure how.

    Im smart in many ways but not when it comes to electricity.
