I make mine out of loose piping, like normal people.

I'd rather have a PAC (Potato gun), much more fun.

Or my paintball gun.

Post by: Colonol Dekker on August 01, 2008, 06:35:04 pm: I just actually opened the link at the top and skimmed it. Any mention of magnetising the ammo? I only caught a mention of bb pellets. I thought the ammo need polarities in or against conjunction of the coil? :confused: I ain't got a clue but i know it shouldn't be inert or the power requirements skyrocket..

Post by: Hellstryker on August 01, 2008, 07:23:37 pm: I think it works so long as the projectiles are iron, not sure though.

As for a PAC, they're loud, bulky, and overused.
I'm talking about a portable firearm for a range or somthing.

In the 1967 Eric Laithwaite described how to make a linear accellarator at home, including a simple half-phase 3-phase converter to power it using normal house power supplies (I think it was actually cut to 16v first, for safety reasons). Of course, it would probably be illegal, even in the US, due to technically being an automatic weapon (anything conductive placed inside the coils would be accelarated, with a single barrel fire rate theoretically exceeding any machine gun, due to the possibility of having several shots in the barrel at once). A 16v, 50-60Hz version probably wouldn't be particularly effective, but a long-barrelled, highvoltage version has be considered for space launch.
