Raspberry Pi Powers Autonomous Nerf Gun Turret
|
5.0
A DIY guide shows how to build an autonomous motion-tracking airsoft or Nerf gun turret using a Raspberry Pi 3 and OpenCV. The project describes two operation modes—interactive remote control with live video and autonomous motion detection—and details mechanical assembly, stepper motor hat wiring, a relay on GPIO pin 22, 3D-printed flanged parts, and battery-powered electronics. The build targets hobbyist security and garden pest control.
Scoring Rationale
Practical, directly usable build instructions increase actionability, but the project is niche hobbyist work with limited novelty.
