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.

Solder the other end of the feedback winding to post number 4. To prevent the two halves of the cores from touching when they are in place, three air gap spacers need to be constructed. Try to come up with some sort of rifled barrel or perhaps adding stabilizing fins to the projectile. homemadw

It should fit well inside the pvc pipe, but not too squeezed. Electromagnetic aircraft catapults are planned, including on board future U. Since losses are proportional to I 2increasing current beyond this point eventually decreases efficiency although it may increase the force.

Solder a length of two-strand wire to the common and normally open contacts on the microswitch. For more information about the project, updates, and movies of the gun in action please visit the EM Coil gun webpage at www. Put the steel next to the coil and see how far it can be while still attracting.

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

Air launch Spaceplanes Laser propulsion Beam-powered propulsion. Another form of Gauss Rifle is one which consists of a strong magnet on a rail. How about cap from microwave plus the transformer from said microwave. The coil gun built in this article is quite simple, focusing on the fundamental concept and availability of materials.

With new research and innovation in high-tech electronic weapons systems, gunpowder may soon become a thing of the past. Solder the other end of the primary winding wire to post number 3. Another coil gunsite www. Pneumatic transport Automated vacuum collection. At low speeds the heating of the coils dominates the percentage efficiency of the coilgun, giving exceptionally low efficiency.


The completed capacitor bank is shown in Figure 9.

Electromagnetic Coil Gun Project

Tips If the coil doesn’t stay, try something to retain it, like steel homejade, or hot glue. This approach sounds very similar to the modern compensated pulsed alternators compulsators being used to power the rail guns being developed at the University of Texas at Austin for the US Army electric gun program.

If the armature is configured as one or more “shorted turns” then induced currents will result as a consequence of the time variation of the current in the static launcher coil or coils. A quick-and-dirty method for switching, especially for those using a flash camera for the main components, is to use the flash tube itself as a switch. However, as speeds climb, mechanical power grows proportional to the speed, but, correctly switched, the resistive losses are largely unaffected, and thus these resistive losses become much smaller in percentage terms.

When the ho,emade is completed, it will be calibrated and fired. The Tools Soldering iron Hot glue gun Wire cutters Exacto knife Screw drivers depending on your disposable camera and your soldering iron, you could need Phillips or Flat The Procedure Build the transformer circuit using the hommemade below, or follow these instructions on how to make the circuit if following the instructable guide, replace the film capacitor used with the one from your camera circuit.

Sir, can i use Elco instead the Film Capacitor, the things quite rare in my country Already answered Not a question Bad question Other.

When you’re done, take out the battery and touch any metal endings especially those of the capacitor with a screwdriver to release any charge.

However, the practical construction of such arrangements requires the provision of reliable high speed sliding contacts. The potentiometer is used to set the exact voltage level on the capacitor bank when calibrating and using the rifle. Click here to share your coilyun. Views Read Edit View history.


The propulsion for these systems honemade the detonation of gunpowder that causes an explosion behind a projectile positioned in a tube barrel that is closed at one end the breech. Most of the work to develop coilguns as hyper-velocity launchers has used “air-cored” systems to get around the limitations associated with ferromagnetic projectiles.

Anatomy of an Arduino Making Electromagnetic Weapons: Fabricate a breech loading device to ccoilgun the projectile into a position where it is partially seated in the coil.

Insert the barrel the empty pen case into the solenoid, and glue it securely so that about an inch protrudes out of one end, and three inches out of the other, like this: Coilgun Mass driver Railgun StarTram. The final step in completing the transformer is to add the E-cores to the bobbin.

A coil gun is homemave device that fires magnetic projectiles at high velocities, using electricity.

All inductance measurements were taken with the iron cores in place. So it all comes from the camera, right? Make a ring out of the steel wire by twisting it with pliers and cutting it.

The doubler cascade is sometimes also referred to as the Greinacher multiplier. The other two wires the other capacitor wire and the other coil wire will be connected whenever you turn on the honemade. 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.

Three of the different projectiles that I have used with success are shown in Figure Need to brush up on your electronics principles?

Coilbun winding the coil one inch from the end of the tube. It was claimed that the gun could fire rounds per minute using a series of electromagnets positioned along the barrel. The completed grip with coiilgun switch is shown in Figure Warnings Wear rubber gloves when firing or handling coiglun avoid getting shocked.
