its been done a million times before, so no point in doing yet another instructable.
however, i do think my coil gun has turned out much cooler than i ever envisioned, and i only zapped myself twice, so i figured id see what you bunch a maniacs thought!
all pretty standard, although personally i was quite pleased with the overall look, and i especially like the simplicity of the cocking mech. all built out of scrap and bits from the poundshop (i love that place. i love it good!) except the magnet wire, which cost me 7 quid from maplins. total cost, prolly bout a tenner.
its meant as a demonstration model, as inspiration for my kid brother, so i havent worried about muzzle velocity or charging time too much, but it charges in about 20s, and is powerfull enough to plink beercans from about 12 ft.
once i get sick of playing fallout im likely to add more caps, and build a faster charger from scratch rather than camera circuits. maybe if im feeling flash, ill add a laser dot, and a solenoid to automatically recock.
take it easy kids!
why? because i can!
