This is how i made my -sort of- remote controllable spudgun ignition
list of stuff to buy before you start on this project with a high awesomeness level:
tools: a wire stripper
tape ( yes , tape is a tool)
hands ( don't lose 'em , they might just come in handy)
Step 1: Drilling
this is the part where you take out your drill , attach a drill bit the size of the threaded part of the spark plug.
Drill a hole in a strong , robust part of the combustion chamber
