Pez Blaster Shoots Candy Dangerously Fast

July 3, 2025 by 3 Comments

You could use a little pocket-sized Pez dispenser if you’re a humble, reserved person. Or, you could follow the example of [Backhaul Studios], and build a dangerously powerful blaster that shoots Pez fast enough to shatter them into pieces. Just don’t aim it at your own mouth.

As the video explains, Pez is really the perfect candy for this application. It’s compact, hard, and already designed to be dispensed via a magazine. It’s thus not a big stretch to set it up to be fired out of a pistol-like blaster. The build is of the flywheel type, where a pair of counter-rotating wheels fling the candy out at great speed. The wheels themselves are spun up to high speed with a pair of small brushless motors, running off hobby speed controllers and lithium-ion batteries. A simple trigger mechanism dispenses the rectangular candies into the wheel mechanism, sending them flying out of the blaster at will. It’s all 3D-printed, designed specifically for the purpose of high-speed candy delivery.

The video goes into great detail on the design, from the development of the TPU treads on the flywheels and other details that helped improve the effectiveness of the design. The final build shoots Pez fast enough that they practically detonate upon hitting a surface.

We’ve featured some innovative work in this space from [Backhaul Studios] before—the condiment cannon was really quite something. Video after the break.

Nerf Blaster Becomes Remote Control Turret

May 24, 2025 by 5 Comments

For most of us, turrets that aim and shoot at things are the sole domain of video games. However, they’re remarkably easy to build with modern technology, as [meub] demonstrates. Meet the SwarmTurret.

The build is based around an existing foam blaster, namely the Nerf Swarmfire. This blaster was chosen for being easy to integrate into the build, thanks to its motorized direct-plunger firing mechanism and electronic trigger. It also has the benefit of being far less noisy and quicker to fire than most flywheel blasters.

For this build, the Nerf blaster was slimmed down and fitted to a turret base built with hobby servos and 3D printed components. The blaster is also fitted with a webcam for remote viewing. A Raspberry Pi is running the show, serving up a video feed and allowing aiming commands to be sent via a Websockets-based interface. Thus, you can login via a web browser on your phone or laptop, and fire away at targets to your heart’s content.

We’ve featured some great turrets before, like this Portal-themed unit.

Building A Nerf-like Rocket Launcher With Airburst Capability

March 1, 2025 by 25 Comments

Nerf blasters typically fire small foam darts or little foam balls. [Michael Pick] wanted to build something altogether more devastating. To that end, he created a rocket launcher with an advanced air burst capability, intended to take out enemies behind cover.

Unlike Nerf’s own rocket launchers, this build doesn’t just launch a bigger foam dart. Instead, it launches an advanced smart projectile that releases lots of smaller foam submunitions at a set distance after firing.

The rocket launcher itself is assembled out of off-the-shelf pipe and 3D printed components.  An Arduino Uno runs the show, hooked up to a Bluetooth module and a laser rangefinder. The rangefinder determines the distance to the target, and the Bluetooth module then communicates this to the rocket projectile itself so it knows when to release its foamy payload after launch. Releasing the submunitions is achieved with a small microservo in the projectile which opens a pair of doors in flight, scattering foam on anyone below. The rockets are actually fired via strong elastic bands, with an electronic servo-controlled firing mechanism.

We’ve featured some great Nerf builds over the years, like this rocket-blasting robot.
