This is a motorized Model Dwarf Multi Cannon from Old School Runescape. The original models came from User Engineer4fun. 

I used a Arduino nano to control the stepper. (Rotates 45deg then pauses at around 18 rpm just like in the game) See attached code for the nano. 

I used the 28BYJ-48 Stepper Motor with ULN2003 Driver which are both placed inside the base. the Nano is connected to the driver via 6 24 awg wires then powered by mini usb.
