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.

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. Or should I always list out the full product details of every component to keep you happy?

DIY Coil Gun Redux: Life Really is Easier with Arduino

Tell us more about it? Open up the soldering gun, and remove everything from inside except the trigger button. The bolt of the loading mechanism that I put together contains a small magnet that holds the projectile in place when the gun is tilted, but does not have enough magnetic strength to interfere with the pulse created by the accelerator coil.

If you decide to fabricate your own projectiles, then experiment with different sizes and weights until you find one that works well. The completed accelerator coil, barrel, and breech loading mechanism are shown in Figure Most conventional firearms operate by the action of expanding gasses forcing a projectile out of a barrel at high speed.

At this point, the transistor turns on again and the cycle repeats. Turn the coil on by hooking it up to a battery.


Are there micros that are in many ways better than Arduinos? By continuing to use our site, you agree to our cookie policy. The Tools Soldering iron Collgun 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.

Of course everything seems difficult when you know less than pigs know cojlgun pearls of it.

Dr. Monk’s DIY Electronics Blog: DIY Coilgun

If the circuit has degraded enough, you might not be able riy replace components if you cannot ascertain the correct original values they only wrote the refdes near the component, not the value, etc…. Where you abuse a very specific logic chip as transistors analog style and limit your fire time with a one shot in the first place. I checked his YT channel and he is in fact German.

Remove all of the wire and tape from the bobbin. The discrete solution has another advantage: Can you give a little more info on what type of diodes, transistors, and transformers those are?

Electromagnetic Coil Gun Project

Before extracting the flash circuit, take the batteries out of the camera and then waste the remaining charge in the capacitor by pressing the shutter and wasting the flash. When the core of the transformer saturates, the induced base voltage goes to zero and turns the transistor off. I bet coilguh could do it with a single push-button and an analog delay line.


We haven’t tested the thing ourselves, but the video below speaks for itself. You’re ready to try it. I have spent way too much time reading over TI flavor of the week dev boards under the thinking that they were better for my small project than an arduino for what ever reason only to discover small bits of errata far to late, and see that TI has dropped support of the board by the time I get around to reusing the board for something else.

It coillgun be done simpler AND better. Accelerator coil, barrel, and breech loading mechanism. Bend the metal and make a body out of that.

With that capacitor, not very. Xoilgun, please either show some respect to the community here, or leave. Cover each layer of 50 turns with electrical tape to secure in place and then wind the next layer on top. But, if my project is a personal project that only needs 20 millisecond response times, then I will probably use a simple arduino to do it.

Make it thick half an inch is quite enough, but the larger the coil, the more powerful the projectile will be when fired.
