Nerf fans rejoice! This custom sentry gun by “BrittLiv” is based on the Nerf N-Strike Vulcan EBF-25 Blaster and is able to autonomously locate / fire at targets. Underneath the plastic casing, you’ll find an Arduino Uno controller as well as servos for movement. Continue reading for a video and more information.
Since the Vulcan has a motorized firing mechanism built in, it was wired directly to the Arduino. She also modified the firing mechanism on the Vulcan, replacing its main spring with one that increases firing speed by about 50%.
It can even be set to ceasefire if you approach it wearing a specific logo on your t-shirt – so you can walk safely in front of it, while your enemies receive the wrath of NERF.
