HOMEMADE COILGUN PDF

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 coilgun or Gauss rifle is a type of projectile accelerator consisting of one or more coils used as electromagnets in the configuration of a linear motor that. A coil gun is a type of rifle that uses an electromagnetic accelerator coil or a series of coils to accelerate a metallic projectile. The Strategic Defense Initiative of.

Interstellar travel Propellant depot Laser communication in space. There are two main types or setups of a coilgun: The accelerator coil creates an electromagnetic pulse that launches the projectile down the barrel. The projectile used for the measurements was an eight gram crossbow tip like the ones shown in Figure Warnings Wear rubber gloves when firing or handling to avoid getting shocked.

Though facing the challenge of competitiveness versus conventional guns and sometimes railgun alternativescoilguns are being researched for weaponry. When you hear the word coilgun, you might imagine a futuristic homemxde that homemafe electricity or coils, but these experimental devices actually use electromagnets to launch projectiles.

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. 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.

When the projectile nears this point the electromagnet must be switched off, to prevent the projectile from becoming arrested at the center of the electromagnet. The adjustable breech is ideal for experimentation with different types and initial positions of projectiles.

The heart of this project is a miniature high frequency transformer wound on a 20 mm x 17 mm x 15 mm bobbin with a ferrite core as shown in Figure 3. Need to brush up on your electronics principles? For more information about the project, updates, and movies of the gun in action please visit the EM Coil gun webpage at www. What DC voltage was the solenoid that you home,ade set on because i don’t want it to fry itself. Tips If your wrapping your own coil, make sure you have about turns, otherwise there will be too much resistance.

The inverter section of the circuit produces a high gomemade, high voltage using an oscillator configuration consisting of transformer T1 being switched on and off by transistor Q1. Once the capacitor bank has charged to the set level, a ferrous projectile is inserted into the breech loading device and positioned partially into the coil by the bolt.

Electromagnetic Coil Gun Project | Nuts & Volts Magazine

Completed circuit board and control panel. Concept 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 uomemade the energy in the capacitors through the coil, and a projectile.

Use a knife or saw with a fine blade to cut the glue at the points where the core halves are in contact if the E-cores are glued gomemade.

Ford class aircraft carriers. This guide is only for the technically advanced!! 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. There will probably be an air gap spacer on each side of the cores and in the middle so that the ferric material of each core does not contact.

With that capacitor, not very. Don’t electrocute yourself Soldering irons are hot, don’t burn yourself!

With no separate propellant charges to load, the researchers envision the firing rate homfmade approximately double. Screw the soldering gun back together, and your done! With the plywood, make a cast to fake the body design. Moreover, the additional pieces of magnetic material in the magnetic circuit can potentially exacerbate the possibility of flux saturation and other magnetic losses.

Make the coil start on the border and end 2—3 inches 5. When firing, the coil of wire induces an intense magnetic field that draws the ferromagnetic coilgu into the barrel. Are Coil Guns New? After that, load your projectile the steel ring and connect the two hommemade left unconnected. What better way to get acquainted with this futuristic technology than to build your own electromagnetic gun!

Many hobbyists use low-cost rudimentary designs to experiment with coilguns, for example using photoflash capacitors from a disposable cameraor a capacitor from a standard cathode-ray tube television as the energy source, and a low inductance coil to propel the projectile forward.

Do not, under any circumstances, use this to cojlgun another human being or animal.

This is a great project to explore a number of analog electronics concepts. The gauss pistol www. 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.

These multi-part series may be just what you need! All of the parts necessary for the circuit are listed in the Parts List. If you use a momentary contact switch, make sure that it is normally open. The Cockcroft-Walton voltage multiplier is an interesting device that was named after Douglas Cockcroft and Ernest Walton. If it doesn’t stay still, use glue coiglun glue it in place while you coil it.

When the current is switched off, the projectile travels forward down the barrel, exits the gun and moves towards the intended target. Share Your Thoughts Click to share your thoughts.

Results may vary, but I was able to launch small metal screws into a piece of styrofoam from about ten feet:
