how to make a coil gun without a capacitor

go here and look at the schematic. RomanS has added a new log for ESPboy - the ultimate multi-gadget. This does simplify the electronics since no capacitor charging circuit is needed. You measure the moment the projectile is at whichever point, and use that to decide when to energise the next coil. Many coil gun and rail gun builds have made it to our pages over the years, including his ridiculously powerful gun that uses a capacitor bank so large it needs its own car.

I didn’t have any small heatsinks sitting around. As soon as the projectile reaches the coil magnetic field kept off, allowing the projectile to continue down the cask at high velocities. 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. The problem is that the traditional coilgun, and the type that this guy is building, is trying to dump all the energy into the projectile in a very short pulse, and as you know the coil is an impedance that resists changes in current, so you need very high voltage to get it to react that fast. Did you know you can read answers researched by wikiHow Staff? Whenever we see a coil gun project on the Internet, it seems to involve a bank of huge capacitors. You can make more layers of wire if you want, but 7-8 should be enough to shoot a projectile. How can i make on of those myself?

But they don’t really get hot. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Coil guns work simply by creating a magnetic field that draws the projectile toward the center of the coil. The copper wire may also be called magnet wire when you buy it from a hardware store. So I guess I’m not crazy after all. Or does it specifically have to be magnet wire? A capacitor is an electrical device that has, in DC circuits, the purpose of storing energy.

In this article, I'll show you how to make a small, weaponized highlighter. The capacitor used was chosen for improved efficiency over the ceramic capacitors used in the original Plasma Gun. Most hobbyist coilguns have an efficiency of 1-2%. You can buy a soldering gun and solder material from your local hardware store. Instead of one or three coils, you need dozens of low-impedance coils that are switched rapidly in a wave sequence over distance to give the projectile some time to accelerate – a linear motor instead of a single impulse. You can use any projectile as long as it’s magnetic. PVC Pipe – 1 inch by 8 inches in diameter will work great for this project. To use a lower voltage, use thicker wire but less of it. Make sure your switch is in the off position before soldering it to your coil gun. If you don’t have electrical tape, you can use clear tape or duct tape instead. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Hi Mehdi, I’m a high school student competing in a science fair, and you inspired me to build a coil gun for my project.

Press down on the tabs with the end of a screwdriver, pulling the case apart while they’re loose. Tip: Save the camera case so you can easily mount the circuit for your coil gun later on. All tip submissions are carefully reviewed before being published. Some capacitors and bigger mosfets may give it a boost until you melt down the magnets, The rail gun requiring a huge amount of amps to create forward movement from the projectile. Alternatively, you could switch both sides of the coil (high side and low side), and clamp with diodes to the opposite sides of the battery. Coil Gun, as many people think (including me) is not just a fun toy with a tube and few coils around it which can shoot projectiles to a certain distance.Scientists at Sandia National Laboratories believe that a coilgun can be engineered to accelerate particles at a greater speed that is high enough to escape earth’s gravity. The bright side of doing this, if it fails as coil gun it still can be useful as linear drive…. Using capacitors may not be the best idea if you are looking to make an efficient gun.

In any case, you can apply much higher field densities without so much loss, yet you don’t need it to be that high because you’re not trying to achieve a huge single impulse, so you achieve much more for much less. Improvements can be made to the charging circuit, capacitor bank, accelerator coil, and barrel design to achieve higher velocities. When coil gun is fired the coil of the wire induces magnetic field that produce ferromagnetic projectile into the cask. I have tried to include some subsidiary information regarding the basic theory behind a simple single-stage coil gun and how to go about constructing one in your home electronics lab.

Don’t cut the wire when you’re finished with the first layer since you’ll use it to make additional layers later on. Wrap the insulation tape above the pipe in succession until it reaches a thickness of 4-5 mm. Place a paper clip inside the coil and insert the battery in the circuit. When firing, the coil of wire induces an intense magnetic field that draws the ferromagnetic projectile into the barrel. The gun isn’t exactly creating plasma discharges with its launches, but it’s a fascinating project nonetheless. http://hackaday.com/2015/11/09/the-most-powerful-diy-railgun/, Very cool magnetic gun. Even when you use an insulated screwdriver, wear rubber gloves as an extra layer of protection.

DO NOT attempt to build this device unless you are experienced with safety, electronics, soldering, and understand circuit schematics. Make sure to wear rubber gloves to prevent any accidental shocks. Does the capacitor for this have to be from a disposable camera? They use a current to charge copper wires and create an electromagnet to launch a projectile. Each of those options will result in a much larger voltage across the coil when it’s turned off, and therefor a much faster current decay. When the projectile leaves the coil and triggers the photo transistor it may already be too late and the projectile will be slowed down by the magnetic field that is still present. Maybe it would be better to have the photo transistor at the ingress end of the coil to trigger when the projectile enters the coil, then have an adjustable time delay to turn the coil off again – this way the setup could be adjusted for optimal performance.. With the flyback diode directly across the coil like he did, it’s going to take forever. Tip: Prop up the end of your coil gun’s barrel to shoot your projectile farther.

Would use 2400mAh, 130 peak C lipo, And an STM32… with many outputs, coupled to IR diodes and fiber optic cables to switch the FETs via IR diode – transistor. However, if you did the same thing over a 20″ linear motor, you’d have ten times more time to accelerate and your peak power drops to 1 kW which is perfectly doable with a small LiPo pack. The rigs have ridges to help you lay the coils down neatly, and they also have mounts for photodiodes, ensuring the gun knows when it’s loaded. A small capacitor, of similar size as the used LiPo batteries should outperform the batteries in delivered peak energy.
