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.

Other components of the gun are the barrel, breech loading mechanism, battery supply, control panel, display, projectile, pistol grip with trigger assembly, and an aluminum stock that contains all of the components.
Thanks for running with the ball. The DC output voltage from the voltage multiplier charges the capacitor bank through the accelerator coil L1, to a voltage that is determined by IC1, a operational amplifier configured as a comparator. If my project needs to work reliably 50 years from now without me around, then I will look elsewhere.
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 to be on and then turn it all off.

If you are not experienced in the fabrication of such devices, then do not attempt to build this project. Mount the potentiometer, indicator LEDs, and switches coligun the control panel and then fasten it to the circuit board.
I used quite a few turns Skip to main content. A metal bender was used to shape the pieces and all holes were made with a drill press. Don’t electrocute yourself Soldering irons are hot, don’t burn yourself! It could be done simpler AND better.
How can we make it more powerful. Diode D9 is required to prevent the voltage from reversing. 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.
What better way to get acquainted with this futuristic technology than to build your own electromagnetic gun! The capacitor bank, side panels, and trigger assembly are shown in Figure The smooth bore barrel causes problems with accuracy because the projectile does not spin to stabilize it while in motion.
This is to avoid getting shocked. These systems are very quiet when projectiles are fired at velocities lower than the speed of sound, are clean, and require little maintenance.
The author and the publisher accept no liability and will not be held responsible for any injury or damages caused by the construction, use, or misuse of this device. Solder the other end of the feedback winding to post number 4.
All inductance measurements were taken with the iron cores in place. Use two position terminal blocks on the board where the capacitor bank, battery pack, fire siy, and accelerator coil are connected. Improvements can be made to the charging circuit, capacitor bank, accelerator coil, and barrel design to achieve higher velocities.
The beauty of that circuit is that you can keep adding stages to it, or intermediate delays by just adding one more and repeating the same.

Use two plastic or cardboard discs glued to each end of the barrel on coi,gun sides of the coil to add support. By using this service, some coigun may be shared with YouTube.
Cut the PVC pipe on the opposite ends to make it about 6 inches Continue this procedure in increments of 50 volts until you reach VDC, marking each position of the potentiometer on the panel face with a pencil or marker as you go. Make way for the electromagnetic coil guns! As mentioned earlier, this is the very simplest version of a coil gun, relative to the materials avalable.
Press it and wait a minute.
Remember that safety always comes first when building and experimenting with high voltage and ballistics. The side panels cooilgun covers are shown in Figure Or should I always list out the full product details of every component to keep you happy? Put the steel next to the coil and see how far it can be while still attracting.
Follow us email facebook twitter Google Plus instagram tumblr pinterest youTube snapchat linkedin rss. Mark V on the control panel at that position with a pencil or marker. Regular firearm handling precautions should be taken.
Are Coil Guns New? Accelerator coil — turns of 20 AWG magnet wire. Even if they did refer to the arduino as a micro, so what? When Q2 is switched on, the base of Q1 is pulled to ground which stops oscillation of the transformer, turning the charging action off. Hilarious Science How To: The force applied to the armature is proportional to the change in inductance of the coil with respect to the xiy in position of the armature and the current flowing through the coil.
Always short out the capacitor bank when working with it or the circuit.
Electromagnetic Coil Gun Project
Cut two more copper wires. The length of these wires may be different, depending on what type of stock you decide to build. Always disconnect all connections when not in use.
What is the ID and xoilgun OD of the preferred tube size? Put the battery you took out in the previous step back where it was.
