It may not be necsesarry to buy a neon transformer, you may get away with a
car ignition coil. I would guess that one ignition coil would equal 1/3-1/4
feet sparks, but if you get two exactly similar ones, you may put them in
parralell and feed them with the same voltage. Then you'll get more current.
Feed the coils with 12 volts square wave or some hundred volts in pulsed
current. If you look at a car ignition system, you may get some ideas.
Personally, I have got sparks well over 2 inches without anything else than
the ignition coil and a car ignition system, and i guess the current may
have been well over 20 milliamps.
