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.

Ok, I am waiting coilgin your blogpost when you do it with an Intel Curie. Concept A coil gun typically consists of a coil s of copper wire similar to a solenoida capacitor bank, a transformer, a DC viy source, a method of releasing the energy in the capacitors through the coil, and a projectile.

Chained Lightning Master the Power: Its expensive to build and takes lots of experience in electrical work. YouTube user Larsplatoon’s 1. This site uses Akismet to reduce spam. Coat all of the capacitor leads and solder connections with RTV silicon rubber or Plasti Dip for safety.

Make a coil with the copper wire around one of the two openings of the PVC pipe wind the copper wire around said opening a hundred or two hundred times. What better way to get acquainted with this futuristic technology than to build coilhun own electromagnetic gun!

Dr. Monk’s DIY Electronics Blog: DIY Coilgun

But you end up designing a folded back on itself oddity that is very difficult to understand and add to, and is highly intolerant of part substitutions. These capacitors are available at most electronics supply companies. Warnings Wear rubber gloves when firing or handling to avoid getting shocked.

Cut two identical pieces of plastic or aluminum and add support pieces of one inch square aluminum tube. It might be interesting to find out how many people adopted that style because it made their handwriting more readable.


Cookies make wikiHow better. Want more news like this? When firing, the coil of wire induces an intense magnetic field that draws the ferromagnetic projectile into the barrel. The inverter section of the circuit produces a high frequency, high voltage using an oscillator configuration consisting of transformer T1 being switched on and off by transistor Q1. Finally, glue the AA battery case into the soldering gun case, and mount the transformer inside as well with hot glue, like this: Wind turns of 20 AWG magnet wire, in six layers of 50 turns each.

The adjustable breech is ideal for experimentation with different types and initial positions of projectiles. The transformer is now complete. Now, please either show some respect to the community here, or leave.

I used quite a few turns After that, load your projectile the steel ring and connect the two wires left unconnected. How about cap from microwave plus the transformer from said microwave. Click here to share your story. Sorry, what exactly is your point?

You should now have a bobbin and E-cores similar to the ones shown in Figure 5-A. However, Arduino clearly makes these known and has a large supportive community, something most microcontrollers do not have. Need to brush up on your electronics principles?

DIY coilgun gives clever hobbyists the risk of permanent injury

Use extreme caution when experimenting coilgu high voltage and capacitor discharge circuits. Crack open the lamp at the seam, being careful not to break the glass tube, and remove the circuit board. It was claimed that the gun could fire rounds per minute using a series of electromagnets positioned along the barrel. He could have used a dip version ciolgun the atmega without the rest of the Arduino around it and it would have been even smaller.

For the solenoid, you most likely will have to remove the plunger and outer casing, so it looks like this:. All of the parts necessary for the circuit are listed in the Parts List. 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.


The design, construction, and operation of the transformer used in this project is explained step-by-step since it is a key component that is often overlooked in articles and books concerning high voltage. A voltage regulator board salvaged from old cell phones keeps the thing from overcharging itself, and a standard trigger mechanism switches the power from 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.

Learning Electronics Need to brush up on your electronics principles? Remember that safety always comes first when building and experimenting with high voltage and ballistics.

Try designing a system with multiple coils, capacitor banks, and a switching device. Now, insert the magnetic projectile in the one inch end of the coil, or the back end.

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. Make sure to discharge the capacitor too do this by firing but ciolgun connecting it back to the battery.

Set up a proper backstop when you are ready to fire the gun and always wear eye protection when operating the device. Desolder any wires attached to the switch. Flashlamp Lasers Making Electromagnetic Weapons: Learn how your comment data is processed. The coil gun built in this article is quite simple, focusing on the fundamental concept and availability of materials.

Completed pistol grip with fire switch mounted. Turn the coil on by hooking it up to a battery.
