Coil gun

Have you ever wanted a futuristic energy weapon?
Build one on your own!


More pictures&videos after the break!



coilgun is basically a electromagnetic linear accelerator.
 So i took an old softair

Softair Model Beretta


and modded a coilgun inside.
Here's the coilgun's circuit:






The capacitor is hidden inside the pistol's grip.
It's capacity is 800 yF at 300V.
The semiconducter I used is a 2N6509.


I added a switch to the trigger.
Pulling the trigger will discharge the capacitor and create a magnetic  pulse which accelerats a small piece of metal.
The kinetic energy is about 0,10 Joule.
 Additionally I modified the reloading mechanism. Pulling back the slide will place a metal projectile in front of the coil.

  6. That's pretty awesome

    but I think you mean uF not yF

  7. What is the charging circuit you used?

  8. how you geht the 300V out ot the 1,5V? thx

  9. Looks like the charger was taken from cheap single-use camera.

  10. Ah jeez, let's see how kids take to making energy weapons now

  11. Single-use camera mated with soft-air? ;)

  12. You could make the forward addition bigger to house the capacitor(s) as well. depeding on the projectile you could still keep the original softair mag in for higher capacity, eventhoug it would still require manual reload.

  13. Cool project! Thx for sharing.
    Which town is in the background?

  15. Its amazing! I like it.

    btw, the background is Tokyo Tower.

  17. this is epic! I've always wanted to make one but I saw that the circuitry for the capacitor looked pretty daunting then i had an idea to use a single use camera for the flash (it's about 240V isn't it?) which would work well. I'm glad someone put the effort in to prove it :D
    I'm way too lazy to make anything like this XD
    nice job!

  18. hrm.. now if we would mod this into a longer barrel, with more coils (and adding capacitors/charge as needed) would it become a sort of long range rail gun :D?.. hahah one of these days im gona craft one but not lookign for anythign lethal, kist to know over some cans XD

  19. Hey,

    Great work. Really awesome hack. Do you have an email address I can contact you on I have a few questions. My email is rgibson(at)farnell.com

    Thanks
