mike b ive never biult these electromagnetic launchers from these schematics i posted, yet but the idea of diagmagnetically repelling alliuminium objects by induction is cool the coil gun if your useing a sieries of coils will need sensers in the design to switch on each coil as the object, being repeled goes through the coil , i geuss like timeing , as for the circuits i posted here you just need to wind that coil the way it says and these coils tap into each other after so many turns, and you dont need the timeing like circuitry to fire each sieries coil when the object enters it as the object sits over the core and the coil around the core energizes this alliuminium object or ring and then it shoots off , there is a site around about useing magnets for shooting objects but you need a sieries of magnets to use for it i used a coil from a car igntion coil, just one coil i removed the fine seconadry winding from the center, just push it out with your finger with the core them i was left with the thick primary still intact i sat a steel nail in it and with each end of the coil i had one end attached to a 12 volts battery not car type, and when i touched the other wire to the second terminal the nail shot out to a good distance , like i was a transister switching it on and off and the speed i did it , the nail dident get sucked back in like an electromagnet it just went through and shot out, not bad for a bit of manual timeing by touching wire to battery terminal
