DIY COILGUN PDF

Updated: April 14, References. They use a current to charge copper wires and create an electromagnet to launch a projectile. To build a coil gun, all you need are a few tools, some wire, and a disposable camera. Tip: Coil the end of the wire around the terminal before you solder if you want a more solid connection. Make sure to wear rubber gloves to prevent any accidental shocks.

In this article, I'll show you how to build a coil gun. A coil gun is a device that fires magnetic projectiles at high velocities, using electricity. Coil guns require no explosive propellant, therefor can be fired an infinite amount of time, providing that there is ammunition and available electricity. A coil gun typically consists of a coil s of copper wire similar to a solenoid , a capacitor bank, a transformer, a DC power source, a method of releasing the energy in the capacitors through the coil, and a projectile.

When firing, the coil of wire induces an intense magnetic field that draws the ferromagnetic projectile into the barrel. When the projectile reaches the coil, the magnetic field is turned off, causing the projectile to continue down the barrel at high velocities.

The coil gun built in this article is quite simple, focusing on the fundamental concept and availability of materials. For more information on coil guns, click here. For the solenoid, you most likely will have to remove the plunger and outer casing, so it looks like this:. Now, insert the magnetic projectile in the one inch end of the coil, or the back end. Aim at a non-living, useless object and press the trigger. The projectile should reach speeds of around 80 feet per second.

As mentioned earlier, this is the very simplest version of a coil gun, relative to the materials avalable. To increase the power of your coil gun, follow this guide Note: This guide is only for the technically advanced!!

Its expensive to build and takes lots of experience in electrical work. Results may vary, but I was able to launch small metal screws into a piece of styrofoam from about ten feet:. Want to master Microsoft Excel and take your work-from-home job prospects to the next level?

Jump-start your career with our Premium A-to-Z Microsoft Excel Training Bundle from the new Gadget Hacks Shop and get lifetime access to more than 40 hours of Basic to Advanced instruction on functions, formula, tools, and more. While wrapping your own coil, try attaching it to a drill or other spinning tool to the tube and attach the wire to it, which will spin the wire around the tube. Can you give a little more info on what type of diodes, transistors, and transformers those are?

I have no idea what the transistor specs are, since there is no writing. I used quite a few turns What DC voltage was the solenoid that you bought set on because i don't want it to fry itself. As well as the duty cycle? Thanks in advance. Sir, can i use Elco instead the Film Capacitor, the things quite rare in my country Thank you In the video, the functioning of the working model of the electromagnetic mass accelerator mobile test stand.

It is generally accepted that the implementation of this design is very difficult because of the low efficiency and low reliability. Nevertheless, this opinion is mistaken - modern technological the base has long been able to realize an electromagnetic mass accelerator with an acceptable efficiency and high reliability I am looking for interested in making.

The Coil Gun: Concept A coil gun typically consists of a coil s of copper wire similar to a solenoid , a capacitor bank, a transformer, a DC power source, a method of releasing the energy in the capacitors through the coil, and a projectile. A capacitor the one from the disposable camera works fine, for this project Wire Solder Nail or similar small, magnetic object. Hot glue Gun-like case I find a great case for everything is a soldering "gun". For the solenoid, you most likely will have to remove the plunger and outer casing, so it looks like this: 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 schematic 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.

Next, extract the capacitor from the camera circuit and place it aside for later. Open up the soldering gun, and remove everything from inside except the trigger button. Desolder any wires attached to the switch.

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: With an exacto knife, slice the one inch portion of the barrel in half horazontally, so it looks like this: Now, mount the coil either inside or on top of the soldering gun case. I couldn't fit my coil into the case, so I stuck it on top it doesn't effect the preformance of the device Solder the coil in series with the soldering gun trigger and the capacitor.

Cut two half circles in each side of the soldering gun. Results may vary, but I was able to launch small metal screws into a piece of styrofoam from about ten feet: Tips If your wrapping your own coil, make sure you have about turns, otherwise there will be too much resistance.

Don't electrocute yourself Soldering irons are hot, don't burn yourself! Same goes for the hot glue gun I am not responsible for any damage or harm you cause with this device Want to master Microsoft Excel and take your work-from-home job prospects to the next level?

Sign Up. I also do that for sanding round things, but the sand paper gets hot really quick. So it all comes from the camera, right? Please enable JavaScript to watch this video. How about cap from microwave plus the transformer from said microwave.

Dear Sir, In this circuit, Which type of Capacitor? How can we make it more powerful. Share Your Thoughts Click to share your thoughts. Hot Latest.

Coilgun Handgun

A common complaint in the comments of many a Hackaday project is: Why did they use a microcontroller? So when [GreatScott] rebuilt his recent DIY coil gun with discrete logic , we just had to get the word out. 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. But when taken to task for that design choice, he rose to the challenge and designed a controller using discrete NAND and NOR gates, some RS latches, and a couple of comparators. The basic control circuit was simple, but too simple for safety — a projectile stuck in the barrel could leave a coil energized indefinitely, leading to damage. What took a line of code in the Arduino sketch to fix required an additional comparator stage and an RC network to build a timer to deenergize the coil automatically. I was almost expecting it to end with a mic drop.

Watch A Homemade Coilgun Destroy A Laptop

This homemade gun uses electromagnetic coils to send steel rods flying at a speed of feet per second. Pressing the trigger loads a steel rod into the barrel, where the first electromagnetic coil pulls the rod forward via magnetism, then turns off. The next coil is triggered on by an infrared sensor, propelling the rod farther down the barrel, and then so on and so on until the projectile flies out with a thwuck! Here's a gif showing how that process works:. Coilguns are an interesting concept, and this one, created by Jason Murray of Delta-V Engineering , is certainly effective at destroying empty cans, a laptop screen, and a slice of cake. Murray should totally get together with that record-breaking slingshot dude.
