Make a small battery operated spark gap?
I want to make a potato gun but I don't want to use a grill ignitor (unreliable) and I don't really want to buy a taser (kind of expensive) to light it. I would really like to build some simple battery powered high voltage circuit capable of making a small spark or operating a spark plug.
I would like it to meet these requirements.
1. Minimal circuitry.
2. No flyback.
3. Fits in/on an altoids tin
I'm still just beginning to understand circuitry so the less complex the better.
