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.

What is the ID and the OD of the preferred tube size? 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. In common coilgun designs, the “barrel” of the gun is made up of a track that the projectile rides on, with the driver into the magnetic homemave around the track. A metal bender was used to shape homemsde pieces and all holes were made with a drill press.

By having the projectile pulled towards or levitated within the center of the coils as it is accelerated, no physical friction with the walls of the bore occurs.

Coilgun – Wikipedia

Be sure not to charge the capacitor bank over volts unless you have installed an SCR that can handle it. Mount the potentiometer, indicator LEDs, and switches to the control panel and then fasten it to the circuit board.

How about cap from microwave plus the transformer from said microwave. This isn’t a weapon. You can use any sort of light plastic or nylon tubing material that can be obtained at most hobby shops. Detach the core parts by unwrapping any tape that may be holding them together.

Like any flash tube, ionizing the gas in the tube with a high voltage triggers it. A design using a microcontroller to coordinate the switching, charging, voltage monitoring, and display would make a multiple coil design much easier to implement.

In a coilguh design, further electromagnets are then used to repeat this process, progressively accelerating the projectile.

The concept of electromagnetic guns has actually been around for a while. Archived from the original on July 8, Make the coil start on the border and end 2—3 inches 5.

Before extracting the flash circuit, take the batteries out of the camera and then waste cooilgun remaining charge in the capacitor by pressing the shutter and wasting the flash.

The doubler cascade is sometimes also referred to as the Greinacher multiplier. It is not a rifle as the barrel is not rifled. Remember that safety always comes first when building and experimenting with high voltage and ballistics.

Coil gun systems www. The trigger switch used is a microswitch type but any momentary contact switch can be used. Arcology Building printing Contour crafting Domed city. Note that the capacitor bank is charged through the accelerator coil. Same collgun for the hot glue gun I am not responsible for any damage or harm you cause with this device. Views Read Edit View history.


When firing, the coil of wire induces an intense magnetic field that draws the ferromagnetic projectile into the barrel. The smooth bore barrel causes problems with accuracy because the projectile does not spin to stabilize it while in motion. Aim at a non-living, useless object and press the trigger. There are several common solutions—the simplest and probably least effective is the homemaed gapwhich releases the stored energy homemave the coil when the voltage reaches a certain threshold.

Screw the soldering gun back together, and your done!

Capacitor energy storage bank wiring diagram. By wiring it in series with the coil, it can silently and non-destructively assuming that the energy in the capacitor is kept below the tube’s safe operating limits allow a large amount of current to pass through to the coil.

Use extreme caution when experimenting with high voltage and capacitor discharge circuits. When the ball is pushed toward the magnet, it coilgub until it hits the magnet with some force and velocity. Other components of the gun are the barrel, breech loading mechanism, battery supply, control panel, display, projectile, pistol grip with trigger assembly, and an homemafe stock that contains all of the components.
