Coil gun

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


More pictures&videos after the break!





A 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.

    3. Clearly you haven't read history about how the U.S. fought for Independence...using guns.

  5. This is some brillant work right there. Damn, this is a lot of work you've put into there!

  8. Awesome.... does it actually work? I want a video!

  11. That's pretty awesome

    but I think you mean uF not yF

  12. What is the charging circuit you used?

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

    1. capacitor from a disposable camera i think.

      Delete

    2. charge circuits from disposable camera's are great, can charge up to about 415-420v if you are using a three volt battery, you can wire them in series to cut down charging times and best of all you can get them for free! go to some place that develops them and ask for the old ones, if asked why tell them you want the battery's from inside
      just be careful as a 400v shock F***ing hurts and can potentiality kill

      Delete

    3. Hurts yes but its noting compared to six of the 330v caps in series. And no it cant kill. There isn't enough energy inside of a 1.5v battery to provide both the voltage and current to kill.

    4. i think you meant parallel, remember these aren't resistors! lol

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

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

    ReplyDelete

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

    ReplyDelete

  18. 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.

    1. It may not necessarily require a manual reload. If you really weakened the hammer spring you could rig a small motor to "cycle" the guns reload mechanism

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

  20. Can you make an Instructable for this project?

    ReplyDelete

  21. Its amazing! I like it.

    btw, the background is Tokyo Tower.

  23. 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!

    ReplyDelete

  24. 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

  26. 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

  32. unfortunalety the projectile isn't as fast as the tiny soft-air bullet fired by the original gun, but it is a nice work at all...

    ReplyDelete

  33. Now what you need to do is Make a Video Of you Making it.... And a list of supplies... Make a simple Version of the Video For idiot to Shoot there eye out...

    ReplyDelete

  34. This is awesome, I would really appreciate it if u could please send me the parts list and step by step plans for this, love your work!
    Thank you for sharing your creativity.

  39. What is the velocity of the projectile?

    ReplyDelete

  40. could you please send me a detailed step by step guide, for doing the same thing working with a cheap bb gun as a case for the wiring/capacitor? bryan.xbox@hotmail.com

  41. Ever built one with multiple coils?

    ReplyDelete

  42. why did you use the 2N6509? cant you use something else instead??

    ReplyDelete

    1. Yes you can use another Thyristor that matches your voltage and current!

      Delete

  43. It's not so hard to make...It's only an electromagnetic linear accelerator on an airsoft gun.

  44. what is the capetel R above the trigger and yes i am a bad speller
