NERF will forever hold a special place in my heart. But compared to Instructables contributor BrittLiv that ain’t nothing, who likely has a heart made of the foamy material as evidenced by this NERF Sentry Gun that fires upon anyone that falls into its field of view.
Yes, unfortunately you will NOT be able to buy this setup in store, but if you’ve got a penchant for building you can follow her step-by-step instructions, and if completed correctly you’ll end up with your very own little brother deterrent. In addition to some serious ingenuity, you’ll also need a computer and a Arduino Uno controller to automate the NERF gun. BrittLiv also modified the gun’s firing mechanism to increase firing speed by 50%, which she managed to activate by wiring directly into the trigger system since it’s already electronic.
So how does one approach the NERF Sentry Gun without getting blasted in the face? Just adorn a t-shirt with the specified logo. Duh.
