With all the recent publicity surrounding guns, Mehdi Sadaghdar (and his eyebrows) of Electroboom decided it’d be a good idea to show the world how to build one. Classified as a “coil gun,” the device uses a coil of wire and a power supply to launch a steel projectile over 16mph. The video outlines how a coil gun works and demonstrates what can go wrong in a way that… well… just watch the video.

Check out Mehdi’s YouTube Channel for more even more educational hilarity. I just subscribed.

I am the Evangelist for the Maker Shed. It seems that there is no limit to my making interests. I’m a tinkerer at heart and have a passion for solving problems and figuring out how things work. When not working for Make I can be found falling off my unicycle, running in adverse weather conditions, skiing down the nearest hill, restoring vintage motorcycles, or working on my car.

    My coil gun is better, I used a capacitor and a light switch, might build your circuit thought!

  2. kevin says:

    … he said 25 kph or 16 mph, NOT 60 mph. need correction in the article

    1. Michael Castor says:

      Thanks for pointing that out! His “16″ sounded a lot like “60″ to me.

  3. Steve Sparks says:

    I have built very successful coil guns with a single coil powered by the flash unit from a disposable camera. It puts out a short burst of 300V from a capacitor, so there’s no reason to have a shutoff controller.

    1. josiah says:

      Short burst spikes magnetism once then goes off. He used AC on the coil so the magnetism doesn’t stop. That’s why he needs a stopper.

    duly noted for the Darwin Award. If you are not having fun when Making, you just aren’t having fun.

    1. Michael Castor says:

      Well said!

  5. Tommy Gunn says:

    that was the funniest maker vid I’ve ever seen… cheers!

  6. miroslava von schlochbaum says:

    That was delightful – thank you. (the only difference if i had made such a video would be that all my silly mistakes wouldn’t have been for comedic effect)

  7. Chris says:

    Okay. Have fun wasting a bunch of money on weapons and burying your guns. Now could you please stop infecting the internet with your poorly written run on sentences and gun-nut propaganda? That would be great.

  8. This is about having fun with making stuff, not a soapbox for a freaked out, scared old white guy who needs to turn everything into an NRA rant. There are tea party forums for that, seriously.

  9. joe says:

    this guy has to be fake. He has another video where he zaps electronics, and “accidentally” touches it before discharging (multiple times). This guy is either REALLY stupid, or just likes attention

    1. Will says:

      Or, and I’m just spitballing here, he makes slapstick parodies of how-to films.

        +1

  10. [...] the article How To (or How Not To) Make a Coil Gun, caitlinsdad [...]

  11. Enrique says:

    very funny and interesting, i have one question, how powerful should a coil gun be to match the power of a regular gun?

  12. Shaun says:

    This guy is an idiot, in a good way. We all need the laugh ;)

  13. teme says:

    Here’s my try:

  14. quinton says:

    Couldn’t you make one out of an electric stapler?

  15. Eli A says:

    I have a CS-6 Longshot Nerf and im trying to find a way to toss a multistager in it… do you guys think that would be possible to do while keeping the clip and reload Parts?
