Well to start with I am from Sweden therefor my bad English.
I build it when i was 15 and it is powered by camping-gas and nitrous-oxide.
the barrel is 2" and the chamber is 3".
It is electorally ignited with about 30sparks/s and outputs about 3700Volts
It also got a flashlight on the end of the lower pipe.
I am sorry for the bad pictures.

It got the same fuel as the one mentoned above.
I have added a silencer and sight. the barrel is about 1,25"
exept spuds it also shots 2 special shots, one loaded with 300V and 4KF capitator and one with razors.

wow, you said that you get 37 sparks? does it have a spark strip or what? it looks much better than my first. what is the tee for? is that how you fuel it or what? nice cannon. you should use zip-ties to hold all the wire together. other than that, it looks really good.
