G36 Coilgun Model Movie Prop

Click here for more detailed pictures and videos of the build!

 This coilgun model movie prop was built inside a fully functional airsoft G36, which cost about 40€ on Amazon.

These are the parts I used for the coilgun movie prop:



I took apart an old flash and removed both transformer and capacitor.

I bought this 4x20 Scope to be mounted on the Coilgun.

Additional capacitors for more capacity.






 
These are stainless steel barrels which
hold the lasers.

The voltage meter will indictate the capacitor's voltage.

Some led-wire was used to spice up the rifle's looks.


Leds combined with a water balance give this little gadget a nuclear battery look.



Why use one led when you can have three?I bought them here.

This is a 11mm and 22mm adapter for scopes and other visual aiming devices.

The Thyristor is the most important part.
It is the switch, which connects the charged capacitor to the coil. I used a S6025L C1 Thyristor. The basic schematic and knowledge about a coilgun can be found here.



This is the night vision camera. It has four infrared Leds for clear sight when it's dark. 




The viewfinder was salvaged from an old analog camcorder.
More information here.






This is the 1 gram
steel projectile. It is just 
a piece of a stainless steel rod. 


This is the transformer. It charges the capacitor up to 350 Volts. The capacitor has a capicity of 1000 uF. You can also see an indicator lamp on the right. It is filled with gas and starts glowing when the capacitor's voltage reaches about 300 Volts.
The next step was to take apart the airsoft toy and create some space inside for all the electronics. I removed the airsoft gearbox and saved it for the automated sentry gun and the remote controlled airsoft turret. This is a standard gearbox available in most countries from ages 14 and up. It has a kinetic energy of less than 0,5 Joules.


I wound the coil with enamelled copper wire: 



As you can see, this is 0,5 mm in diameter enamelled copper wire. I used 46 metres for the coil. The coil itself is about 24 mm long.






 
I removed the airsoft gearbox and made some space for the transformer, voltage meter and coil inside the movie prop: 
I bought the 500V led backlight voltage meter on ebay for about 11 €. The main trigger circuit looks just like this:


Of course, the trigger switch was hooked up to the airsoft toy's trigger. The secondary circuit is pretty straight forward: The voltage meter's measuring inputs are directly connected to the capacitor, the night vision camera's signal output is connected to the viewfinder's input and all the leds are connected to the batteries.
After many hours of wiring and soldering everything was ready to be powered up by the two 9 Volt batteries inside the magazin:

There are four springs mounted on top of the magazine. Sliding in the magazin connects the batteries to the leds, night vision camera and viewfinder, transformer and the trigger ciruit. If you want to know more about the night vision camera, here's a whole article about it.





Here's a video demonstration showing the model's different features like the night vision, powering up through sliding in the magazine, laser sight and capacitor charging:

  4. OH...myyyyyy~!

    And THIS is why I follow your blog~! Someday after I handle a few other priorities, I am SO going to do this, just to add it to my arsenal. :D

  5. Did you actually tune the capacitor to the size of capacitor you where using or did you just wind a bunch of wire and hope for the best?

    ReplyDelete
  6. How much will this cost? Cause I would gladly make one if it is within my price range

    5. I would also be interested in a kit...cost analysis would be nice though.

      Delete
    6. I think the kit idea is great! I would buy it, too! Even if it didn't have all of the same things you did for customization, like the lights and stuff, it could be cheaper and you could tell people how to add them if they wanted.

    9. I want to build a coilgun myself, but I am not sure how to connect the parts. I think its VERY dangerous to work with so much energy. So I would like it, too, if you create a kit with plans, but I think that a list of links where to buy the parts is better than the parts themselves, because I have already some of the parts. I'd like you to send me an e-Mail too, if you decide to sell the plans: mc.pro.99.nst@gmail.com (PS: I'm german but I am not sure if you are, so I used my english skills which aren't so great. ;D )

  16. So to make a working coilgun, all you need is a capacitor, thyristor, voltmeter and the transformer from the camera? All the other bits are just for looks etc.

  34. Add some line spreader prisms to the lasers and it just might form a crosshair assuming they're lined up properly with the barrel.

    ReplyDelete
  35. and by the by, those lasers are clearly not aligned properly

  36. I would like to know if it would be plausible to make an insertable magazine with the batteries as well as the projectiles, I would also love to build one of these but just don't have time, I am also unsure if this could be shipped to Australia but would love an indepth build video and would pay for a complete breakdown or build materials.
    Cheers Benji

    Replies
    1. It would be possible to design a magazine with projectiles but that would be pretty difficult... I am sorry I am not able to ship this due to its obvious looks!I am sorry all that is available is already in this post - there are no schematics since I connected all the devices one by one during the building process! But If you start your own project I could help you with your problems and designs!

      Delete
    2. 2 more questions if I may, Is there any way to reduce the charge time between shots?
      Could you hold down the trigger for an infinite amount of projectiles as long as there is sufficient amount of capacitor?
      I understand that your design has a single fed chamber but if I could design mine with a magazine and complete firing assembly that works as long as enough charge to keep firing I would only need to get the resource/ portable power management down pat, cheers for listening to my rave

  44. Hi! I am also building a coil gun (not this exact same model) but, I am having trouble finding a voltmeter that is similar t yours. The ones that I find only read up to 100 volts while my capacitor is rated for 300 volts. Also, If I use a disposable camera charging circuit and capacitor, will 1 capacitor be enough if it it rated for 300 volts? If not, then how many should I connect in a parallel? Please reply at your convenience. Thanks!

    1. There are three seperate circuits inside the G36 Coilgun. One for the camera and viewfinder, one for all the Leds, lasers and gadgets and one for the capacitor, charger and thyristor! You can see an example for the last circuit on Coilgun Knowledgebase. Sadly there are no blueprints of the whole cirucuit!

  53. also the voltage meter is being a pain to find, also could i use rechargeable batteries like this http://www.batteryjunction.com/ipowerus-9v-520.html or even this since it has a higher mah but it has lower voltage is that a problem http://www.hobbyking.com/hobbyking/store/__11911__turnigy_nano_tech_2200mah_3s_25_50c_lipo_pack.html because i worry about the batteries going out quick having to take it apart just to throw in another battery pack.

    I am not interested in building a coil gun, but in putting some of the extra features on a Airsoft rifle.
    Most interested in the camera and view finder , and the three extra barrels with lasers would be nifty.
    Spicing up the rifle with the LEDS also cool, I'd want to know how to do it, even if I didn't do it!

  64. @DoItYourselfGadgets

    For my coilgun, I'm using 400V capacitors bought specifically for this project and not salvaging it from a camera flash.

    Do you know where I can get a transformer(9V-12V input, 350V-370V output)?

  74. I think love to see the FPS rate of the projectiles listed. You'd probably have to get a radar gun like they use for baseball, and do the conversion from miles/hr (or, of course, the metric equivalents -- please excuse my American assumptiveness!)

    Also, if you do decide to sell kits, it might work best as a business model if you let them choose, via a web form if you can, which optional items to include (lasers, scope, viewfinder, LED decorative lights, etc.) with associated costs. You could probably make a 50% markup from costs, because people would appreciate that you have collected everything together for them, and they love your concept and idea and want one of their own. And, of course, their is all the labor involved in putting the orders together and shipping them.
