G36 Coilgun

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

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

These are the parts I used for the coilgun:

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 laser when you can have three?

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.

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.

This is the 4grams
steel projectile.

This is the transformer. It charges the capacitor up to 350 Volts. The capacitor has a capicity of 1000 uF.
The next step was to take apart the G36 and make some space inside for all the electronics.

I wound the coil with enamelled copper wire:

As you can see, this is 0,5 diameter enamelled copper wire. I used 46 metres for the coil. 







 
I removed the airsoft gearbox and made some space for the transformer, voltage meter and coil: 

After many hours of wiring and soldering everything was ready to be powered up by the two 9Volt 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.
