Sentry turrets based on the Raspberry Pi or Arduino are a popular type of maker project, and this one is worth looking at for its impressive design and use of a new platform called n.io. The ...

The Arduino-driven turret uses two micro servos controlled with pots to move by degrees in X/Y space. Interestingly, [Afroman] doesn’t program the board in the Arduino IDE using wiring.

A student in the University of South Florida Makecourse has created their own version of the Turret from Portal, based on an Arduino and complete with lasers activated by motion. The core of the ...

The Arduino microcontroller is responsible for interpreting the data from the webcam and controlling the motors that aim and fire the Nerf guns.

What starts as a fun NERF showdown quickly turns into a full-blown turret war—and Hacksmith’s not ready for what’s coming. With precision targeting and rapid-fire chaos, the custom-built ...

It also comes with four Nerf guns which use flywheels to launch the darts. The wheels are powered using quadcopter outrunner motors that spin at 25,000 RPM.

A new life-size Portal Turret has been created using 3D printer parts which took over 300 hours to print and is capable of firing up to 400 rounds per minute thanks to the four fully functional ...

The turret combines an IP webcam, a laser pointer, two mini USB rocket launchers that shoots foam bullets, an Arduino microprocessor, and MATLAB, a high-level technical computing language.
