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.

The smooth bore barrel causes problems with accuracy because the projectile does not spin to stabilize it while in motion. The final step in completing the transformer is to add the E-cores to the bobbin. In the video, the functioning of the working model of the electromagnetic mass accelerator mobile test stand.

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

When the current is switched off, the projectile travels forward down the barrel, exits the gun and moves towards the intended target.

We haven’t tested the thing ourselves, but the video below speaks for itself. It should fit well inside the pvc pipe, but not too squeezed. Email required Address never made public. The operational amplifier IC1 is configured as a voltage comparator and is used to set the amount of voltage charge on the capacitor bank. When you hear the word coilgun, you might imagine a futuristic weapon that shoots electricity or coils, but these experimental devices actually use electromagnets to launch projectiles.


Accelerator coil — turns of 20 AWG magnet wire. 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.

Include your email address to get a message when this question is answered. Are there micros that are in many ways better than Arduinos? The basic control circuit was simple, but ciilgun simple for safety — a projectile stuck in the barrel could leave a coil energized indefinitely, leading to damage.

Set up a proper backstop when you are ready to fire the gun and always wear eye protection when operating the device.

Electromagnetic Coil Gun Project

The DC output voltage from the voltage multiplier charges the capacitor bank coklgun the accelerator coil L1, to a voltage that is determined by IC1, a operational amplifier configured as a comparator. I suggest setting up all of the electronic components on your workbench to calibrate the gun before assembling all of the parts into the stock.

Destruction begins around 2: Cookies make wikiHow better. There is possible ways to get clever and design a WTF circuit I think. I have no idea what the transistor specs are, since there is no writing. The pistol grip can be configured however you like, just as long as you can mount a fire switch. A voltage regulator board salvaged from old cell phones keeps the thing from overcharging itself, and a standard trigger mechanism switches the power coilgum the charger to the gate that dumps all the energy stored up in the capacitors to the coil, which generates a magnetic field strong enough to hurl a metal projectile downrange.


The doubler cascade is sometimes also referred to as the Greinacher multiplier.

Already answered Not a question Bad question Other. EM Coil Gun Website www. A common complaint in the comments of many a Hackaday project is: The other two wires the other capacitor wire and the other coil wire will be connected whenever you turn on the coilgun.

Dr. Monk’s DIY Electronics Blog: DIY Coilgun

For example, the bugs about powering the coils on indefinitely would be solved by a one-shot timer at the trigger, which would enable power to the relevant circuits for the few milliseconds they actually need coilgin be on and then turn it all off.

These devices substitute electromagnetic EM propulsion for gunpowder with nearly equivalent results in speed and kinetic energy.
