That reminds me I wanted to build a firecracker shotgun. Still haven't figured out a sleek way to ignite them though.
I'm sure an internal striker could be engineered with some metal bits, maybe a 3D printer, and parts of a zippo lighter. Just shooting from the hip, but I bet there is someone with the knowledge and the time, if you brought the idea up to the correct forums.
My idea was glueing some copper wire to the bottom of the fuse and using a battery powered ignition mechanism but maybe I'm overthinking it 😅
Perhaps a door mouse could be trained to strike a match before retreating safely to a secondary chamber?
But then you have to train a cat to buy more matches at the store for the mouse and they always try to eat the money.
I made a firecracker gun out of lego technics when i was young. The munition was a firecracker too, was pretty fun.
Very rich fuel air mixture and a spark igniter?
Safer and less fun way, heating element.

Yeah that's what I've been considering now. Not just because of safety but also because it's reliable since nothing needs to be directly fitted into the chamber. Also more resistant to soot buildup. Maybe I can repurpose an old vape.
