Modified R/C Jet Cannon Spews Nerf, Slays Cardboard Tanks

[ajw61185] made a video overview of a radio-controlled A-10 jet modified to spew a hail of harmless Nerf balls as it strafes helpless cardboard cutouts of T-72 tanks on a bright, sunny day.

A10 Nerf LoadingThe firing assembly in the jet comes from a Nerf Rival Zeus Blaster, which is itself an interesting device. It uses two electric flywheels to launch soft foam balls – much like a pitching machine. With one flywheel running a little faster than the other, the trajectory can be modified. For example, a slight topspin gives the balls a longer and more stable flight path. Of course, foam balls slow down quickly once launched and at high speeds the aircraft can overtake the same projectiles it just fired, but it’s fun all the same.

Cramming the firing assembly into aircraft took some cleverness. The front of the jet contains the flywheel assembly, and a stripped-down removable magazine containing the foam balls fits behind it. A flick of a switch on the controller spins up the flywheels, and another flick controls a servo that allows the balls to enter the firing assembly and get launched. The ammo capacity on the jet is low at only twelve shots per load, and it fires all twelve in roughly half a second. Since the balls are fired at the ground in a known area, they’re easy to retrieve.

Automated Star Wars Themed Nerf Targets

When challenged with making a game for a kids event using only the parts he already had on hand, [Nathan Gray] had to get creative. What he ended up making is pretty awesome. It’s a Star Wars themed Nerf gun shooting gallery.

icons-390Using a Teensy 2.0, he’s controlling nine RC servo motors attached to two-sided targets which randomize themselves every round — The Empire is bad, the Rebels, good. They’re also color coded red and green in case the images are too hard to see.

To keep track of scoring, there are piezo elements which register the impact of a Nerf dart. A cute little command console with a big red start button and score display can be set up in front of the range to let the kids know how they’re doing.

Homemade Nerf Blasters With 3D Printed Parts

esltcollagesuperawesome

This spectacular bullpup nerf gun was developed by the guys over at Mostly Harmless Arms. It is complete with 3D printed parts in a variety of colors. The Extension Spring/Latex Tubing (ESLT) Blasters were based off of [Kane]’s snapoid trigger design with 1/4″ aluminum for the plunger rods which worked out really well. [Prince Edward] adapted [Kane]’s work and modified it with 3D printing in mind. The original post from 2012 gave an in-depth look into where the idea started.

The documentation for all the printed part files and high quality photos can be found on Nerfhaven. It is really nice to see such a clean design that can be fashioned together on a relatively small budget. This makes these playful nerf blasters easy to duplicate, allowing for a full out office war. Granted, access to a 3D printer is needed, but additive manufacturing devices are getting more and more common these days. Now it’s just a matter of seeing how well they work, which can be deduced from the videos after the break:

Open-Source Sentry Gun Plans Promise the Next Level of Office Warfare

We admit it, we were browsing Reddit when we found this beautifully hacked together Nerf Sentry turret. But are we ever glad we did — as it turns out, it is very similar to the totally awesome, open-source Project Sentry Gun.

We have actually covered a project that used that system before, but it looks like it has evolved a bit more since then. It’s just too cool not to share.

The system itself is quite simple and easy to build. You’re going to need three servo motors, an Arduino, a webcam, and assorted wires, nuts and bolts, etc etc. Grab a copy of the code, slap it all together, and you’re ready for business!

Just take a look at the following video of the Gladiator II Paintball Sentry Gun — we know you’re going to want to build one now.
