Chris from PyroElectro.com has put together a tutorial on how to make a “Tupperware Turret”:
This "Tupperware Turret" is a highly modified airsoft pistol put onto a pan and tilt platform with a turret cover. It rotates, tilts up and down and has precise fire control. Control is done wirelessly with a generic TV remote control.
