Coilgun

This is an older project that i built for a physics contest.

Similar projects worth following
This is a simple coilgun powered by 4 9v batteries and a capacitor bank (8*4700uF). The switching is done with a thyristor (40TPS12A).
If anyone wants the schematics, message me and i'll look try to find them because this is a fairly old project.

First up i prototyped the circuit to see of it works with the parts that i was able to source.

Everything worked well but the coil needed work.

    Initially, the body was made from insulation foam, just because it was easy to work with and it was what i had on hand.

    However, this design proved weak in the middle. Also, i learned that the barrel needs to stay above the trigger, otherwise the gun is awkward to hold.

How powerful was it?

  Are you sure? yes | no

Not very. The little metal ball travelled 2-3 meters, but it was enough to prove the principle.

coil guns are expensive to make

thats the annoying thing

  Are you sure? yes | no
