So when [GreatScott] rebuilt his recent DIY coil gun with discrete logic, mechanism for a small coil gun, and as such he chose an Arduino to. How to Make a Coilgun. When you hear the word coilgun, you might imagine a futuristic weapon that shoots electricity or coils, but these experimental devices. A coil-gun uses a magnetic field to accelerate a bullet up to projectile speed. Jason’s uses a bank of recycled rechargeable laptop batteries to.

I couldn’t fit my coil into the case, so I stuck it on top it doesn’t effect the preformance of the device Solder the coil in series with the soldering gun trigger and the capacitor. A coil gun typically consists of a coil s of copper wire similar to a solenoida capacitor bank, a transformer, a DC power source, a method of releasing the energy in the capacitors through the coil, and a projectile.

Coil gun systems www. The EM coil gun design can be used as a starting point for more advanced experimentation.

How to Make a Coilgun: 7 Steps (with Pictures) – wikiHow

How about cap from microwave plus the transformer from said microwave. These systems are very quiet when projectiles are fired at velocities lower than the speed of sound, are clean, and djy little maintenance.

The adjustable breech is ideal for experimentation with different types and initial positions of projectiles. How to Make a Coilgun Author Info. It was claimed that the gun could fire rounds per minute using a series of electromagnets positioned along the barrel. I have no idea what the transistor specs are, since there is no writing. Solder one end of a piece of 26 laminated magnet wire to post number 2 and then wind the primary coil of 10 turns clockwise around the top half of the bobbin as shown in Figure 5-B.


A fully functional rail gun was developed for this program although it was never deployed in space. Wrap the secondary winding with a layer of transformer tape and then coat the solder connections with silicone rubber or a similar insulating material as shown in Figure 5-F. This isn’t a weapon.

Connect the 12 volt battery pack, fire switch, accelerator coil, and capacitor bank to the circuit board. The projectile should reach speeds of around 80 feet per second. What DC voltage was the solenoid that you bought set on because i don’t want it to fry itself.

Remove all of the wire and tape from the bobbin. Most conventional firearms operate by the action of expanding gasses forcing a projectile out of a barrel at high speed.

DIY Coil Gun Redux: Life Really is Easier with Arduino

This article will describe the general construction of the electromagnetic coil gun shown in Siy 1. A large electric current is switched from a fast discharge storage device usually a capacitor bank into a coil of wire wrapped around a barrel to produce the strong magnetic field required for the rapid acceleration of the metallic projectile.

Do not touch bare wires with your hands.

The EM coil gun stays well below the legal velocity limits in Canada and the US, but because of the projectile weight, it should still be considered dangerous. Did this article help you?

How To Make A Coil Gun: Turning Electricity Into Velocity « Fear Of Lightning :: WonderHowTo

Want more news like this? You can prototype with an Arduino Mini which uses a surface mounted CPU on a DIP carrier and produce a single board version of the project later with either type of mount.

Coil guns require no explosive propellant, therefor can be fired an infinite amount of time, providing that there is ammunition and available electricity.


Sorry, what exactly is your ciolgun Cookies make wikiHow better. These devices substitute electromagnetic EM propulsion for gunpowder with nearly equivalent results in speed and kinetic energy.

By using this service, some information may be shared with YouTube. Accelerator coil — turns of 20 AWG magnet wire. The DC output voltage from the voltage multiplier charges the capacitor bank through the accelerator coil L1, to a voltage that is determined by IC1, a operational amplifier configured as a comparator.

When fire switch S3 is closed, voltage is applied to the gate of the SCR, switching it on and dumping the charge across the capacitor bank into the accelerator coil L1.

Electromagnetic Coil Gun Project

And in fact, its more of clilgun development board for a microcontroller, but that is neither here nor there. The final step in completing the transformer is to add the E-cores to the bobbin. Press it and wait a minute. Warnings Coigun rubber gloves when firing or handling to avoid getting shocked. You are commenting using your Twitter account. All of the parts necessary for the circuit are listed in the Parts List.

His build was more about exploring the concepts and working up a viable control mechanism for a small coil gun, and as such he chose an Arduino to rapidly prototype his control circuit. I also do that for sanding round things, but the sand paper gets hot really quick.

Now, insert the magnetic projectile in the one inch end of the coil, or the back end. After that, load your projectile the steel ring and connect the two wires left unconnected.
