How Many Joules Through The Coil?
So I have all this black powder and I have been thinking about building a small rocket with some. I would like to create an electical ignition system using perhaps a battery, a capacitor, and some sort of resistance-type heating element. Has anybody built something like this?
Trig IS fun.

Estes has...minus the capacitor.
BP is tough to make into a rocket motor. It needs to be very finely ground and packed at a high pressure. All of this makes it rather dangerous to do. Shocks aren't good for it, it can ignite. Once the motor is made there is a high likelihood that it'll have voids in the grain and it will CATO.
If you store the motor, watch for temperature cycling, it can crack the grain.
