Declare war from your desk with this 3D printed Nerf turret powered by a Raspberry Pi
You can even aim it with your phone.

What's better than a Nerf gun war? A technologically advanced Nerf gun war. People have found all kinds of ways to modify their Nerf guns, but I've never seen someone create one with a 3D printer and a Raspberry Pi. Well, if you're in the mood to declare war from the comfort of your own desk, this SwarmTurret project seems like just the thing you're looking for.
