I would like to know how to make a small one that is able to give a charge to beable to ignite an amount of gun powder, i have been thinking of many things how to but i dont really have one that is built or anything. and i am trying to make it work from a good enough distance. Any ideas or a way to get one that will work about 99.99% of the time. I already have a corded one with speaker wire which works but it envoles a way that you have to something else to make it work successfully.
