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!

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.
