This is the circuit behind the coilgun electronics built into the model. These electronics simulate a coilgun and add to the futuristic theme with their distinctive charging sound and energetic nature.
A real coilgun is basically a electromagnetic linear accelerator.

I used a toygun’s hull and modded a coilgun inside.
Here’s the coilgun’s circuit:
As you can see, the copper coil is placed in the center and the electronics are fit inside an extension at the front.
The capacitor is hidden inside the model’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 in theory accelerates small pieces of metal.
The distinctive and fascinating sound of charging and discharging the capacitor adds another level of realism to the futuristic theme.
The kinetic energy of the real circuit is under 0,08 Joule.
Additionally I modified the reloading mechanism. Pulling back the slide will place a metal projectile in front of the coil.
This model looks like something straight out of a video game. Designing something futuristic one must allways try to use technology that already exists. The next step is imagining what could be possible with parts and components that are lighter, smaller and more powerful. Take all of this into account and you’ll end up with a realistic but futuristic piece of technology.
Here are more of my models and designs.
Now that is Awesome! I so wish i had one! <3
0:27 *ducks* damn man don't point that thing at the camera 😀
Very intuitive love to make one 🙂
Wow, I want that so, so bad!
This is some brillant work right there. Damn, this is a lot of work you've put into there!
WOW
Friggin. Genius.
Awesome…. does it actually work? I want a video!
That's amazing 😀
That's awesome.
That's pretty awesome
but I think you mean uF not yF
What is the charging circuit you used?
how you geht the 300V out ot the 1,5V? thx
Looks like the charger was taken from cheap single-use camera.
Ah jeez, let's see how kids take to making energy weapons now
Single-use camera mated with soft-air? 😉
crazyy!
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.
Cool project! Thx for sharing.
Which town is in the background?
Can you make an Instructable for this project?
Its amazing! I like it.
btw, the background is Tokyo Tower.
now make it shoot lasers =)
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 😀
I'm way too lazy to make anything like this XD
nice job!
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
haha thats really cool xD
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
Ryan
i want to make one but i know id end up messin it up! lmaooo
wow you're pretty good at this
Can you send me the step by step? My e-mail is lopusvm@hotmail.com

Yes,it is so bad because it's a gun
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…
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…
Me too plz.. Gemmaster22@gmail.com
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.

you could make money off this
are you blind scrool up lol
Dumbass
capacitor from a disposable camera i think.
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
Bạn có thể gá»i cho tôi từng bước? E-mail cá»§a tôi là ngocduc71785@gmail.com …. thanks
Semiconductor or transistor?
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.
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
Por favor enviame los pasos y la lista de materiales, quiero hacer una.

What is the velocity of the projectile?
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
Ever built one with multiple coils?
why did you use the 2N6509? cant you use something else instead??
Yes you can use another Thyristor that matches your voltage and current!
i think you meant parallel, remember these aren't resistors! lol
It's not so hard to make…It's only an electromagnetic linear accelerator on an airsoft gun.
Clearly you haven't read history about how the U.S. fought for Independence…using guns.
what is the capetel R above the trigger and yes i am a bad speller

please can you make a tutorial of how you build that coil gun? and are you from spain or colombia?
swag
I was thinking of making one of these, but what do you use as ammunition?
hey I am new at this I would like a list and instructions my email is
Graywolf7412@yahoo.com
thank you
Hello, can you please send me a tutorial or instructions about how to make this?
