Today I will show you how to build a super simple arm mounted nerf blaster.
Step 1: Parts
You will need:
- A Flex-meter wrist guard
- 5v mini Solenoid
- Any motorized nerf blaster (I used the Stryfe)
- A Pushbutton
- Male-Male jumpers
- Female-Female Jumpers
- Male-Female connector
- Zip ties
- 9v battery plus connector
Step 2: Take Out the Dart Launcher of the Nerf Gun
I just copied text from a previous Instructable I wrote about taking apart a 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: Assemble the Project
The build is actually pretty simple for this project. It took me about 20-25 minutes to figure out how to build and build. Have fun!
- Detach the plate of the wristguard from the soft part. The soft part does not come off completely, but it will come off enough.
- Put the 9v battery with clip in between the plate and soft part of the wrist guard.
- Zip tie the dart launcher to the front of the wrist guard. You have to run the zip ties through the loops of the elastic band.
- Zip tie the solenoid towards the middle of the plate.
- Assemble the button apparatus as shown in the image.
- Wire it all together with the female and male jumpers. I think the picture does a pretty good job of showing how to do it, but if you want more direction just comment and I will add another image or more text.
- Fire it up!
Step 4: Mods
This project is ripe for mods. One suggestion is to add a sensor to be the trigger. A muscles ensor in particular would be very neat for a trigger. Another mod would be to 3D print a case with a slot for the battery. Tell me what you rigged up in etc comments. Happy Making!
