If you want to truly protect your family from dangerous home burglars, or alien invasions or the rise of the machines, you'll build yourself a turret from recycled scraps and Tupperware like Chris from PyroElectro.
The turret is designed to rotate 180 degrees with a 45 degree vertical tilt. But the best part is that the whole thing can be controlled by a generic television remote, with the left and right arrows controlling rotation, up and down controlling the turrets aim and the OK button cancelling all movement actions. The remote's green button gives the order to fire.
So, who's going to create one of these to protect themselves in the inevitable zombie apocalypse?
