Say Hello to My Little Heat-Seeking Nerf Machine Gun

The winner of last month’s MAKE gadget design contest was this beast by Rick Prescott: A Nerf machine gun that automatically detects hapless warm-blooded people in the vicinity (sadly, ineffective against zombies), swivels, and rapidly fires darts at them.

Prescott:

An idea sparked in my mind one day while walking the toy gun isle in a store with my kid and later that evening learning of the workings of a thermopile array while surfing the internet. The result is this infrared seeking sentinel which joins a realistically priced infrared sensor to a realistically operatable Nerf® machine gun to create a slightly less deadly yet still highly deterring automated machine. Personally I have grand plans to deploy the infrared seeking sentinel facing the entrance of my work cubical in order to speed interaction with less desirable visitors.

Watch it in action:
