In this video I will show you how to turn on and off coils precisely in order to create a coilgun. In my case it is a pretty harmless "gun" that can accelerate ferromagnetic projectiles to safe speed levels through two coil stages. Let's get started!

Step 1: Watch the Video!

The video gives you a good overview of what is necessary to create your own coilgun. During the next steps I will present you some additional information.

Step 2: Order Your Parts!

Here you can find a parts list with example sellers for your convenience.

Step 3: Print Your "Gun"!

Here you can find and download the blueprints of my coilgun, the 3D model and the .stl file for your 3D Printer.

Step 4: Create the Circuit!

Here you can find the schematic of the circuit and reference pictures of my perfboard design.

Step 5: Upload the Code!

Here you can download the Arduino sketch/code that I created for this project. It works pretty well but feel free to fine tune the code to your likings.

Step 6: Success!

Awesome! You did it! You just created your own Coilgun!

<p>is there anything i can use in place with for the driver? i can't find any in stock for a good price </p>
<p>I have ordered parts for this projects could you send me diagrams and schematics of what goes where on the pcb board and coil I am not very techy. Send at aaed.sales@gmail.com.</p>
hi, nice work.<br>y did u use a arduino nano?<br>i know how a coil gun works i had build one before. will u please tell me how your coil gun works.
