Modder Rick Prescott converted a standard Nerf Vulcan EBF-25TM into an autonomous, heat-seeking sentry gun for MAKE’s weird gadget contest. Technically speaking, “Prescott paired a Nerf Vulcan machinge gun with some Devantech TPA81 thermo sensors and a ATmega168 microcontroller.” Video after the break.
