Today I will show you how to build a super cool nerf cannon. This is a cheap and easy tech project for beginners or experts. All you need are a nerf gun, a micro controller and some wire and you're on your way to weapon that will own in a nerf war.

Step 1: Parts List

These are the parts you need:

Makeblock Orion microcontroller
Makeblock BLE Module for Orion
Extra Motor Module for Orion
A 5v mini-solenoid
A nerf Stryfe blaster
12 hole beam
5 hole beam (2)
Various screws and nuts
Mini Breadboard
Jumpers

Step 2: Prep the Nerf Gun

This part is fairly straightforward. Unscrew all the screws holding the shells of the Stryfe blaster together. Once you have done that, you should see a circuit board with a disc poking out of it (which is called a capacitor). It should have a few wires coming out leading up to the dart launcher. This small circuit regulates the flow of electricity to the launcher. Cut the wires of that circuit. Once you have done that, take out the dart launcher. You can keep the remains of the blaster if you want, but you won't need it. Time to assemble the launcher.

Step 3: Assembling the Launcher

Get out the 12 hole and the two 5 five hole beams. Count 8 holes up on the 12 hole beams and attach the 5 hole beams.
Zip tie the solenoid towards the front of the five hole beam stack.
Zip tie the nerf launcher within a 1/4 inch of the length of a nerf dart away from the solenoid.
Set up the Orion and the modules by wiring the ble module to port 5 and the motor module to ports 1 and 2. After that, wire the solenoid and the launcher to the makeblock motor module as shown in the image.
That's it assembly wise, so now it's time for mods!

Step 4: Mods

There are tons of possibilities for mods for this project. I mounted my cannon to a Bluetooth controlled tank frame, so you could build a tank and do the same. You could also add handles to the launcher and make it a hand held blaster. Or, if you just want a powerful nerf gun, only do step 2 but leave the launcher inside.
