A little thing I put together in a few days. It can fire all 11 rounds up to a meter, in under a second. It has unlimited rotations and little under 50 degrees of elevation.
Completion date: 30/10/11
Weight: 602g (21oz)Dimensions (with turret in lowest position): 32x18x28 studs
Power: electric (power functions)
Motors: 2x XL Motor 1x M Motor
the idea was simple: a working full R/C gun and this is what I came up with. although the range is pathetic, one meter (3 ft) at best, due to not-so-strong spring, but it's heaps of fun. I later had the idea to use an 8-way joystick (thank you Jason Railton!)and it makes so much of a difference.
the mechnisim: the wheel constantly pull's the spring back then releases it. the spring's useful shape made it easy to build. the ammo clip only has a 1x1 hole to fall down so the clip stops when there is a new projectile ready. due to the fact that gravity only falls down, when the barrel is in the highest position it mostly only fires one projectile. the mech is based on the one Sariel used in his tripod gun (actually the whole thing is very heavily based on that!) if i had another working M-Motor (I have one dead one) i would use it for rotation, but an XL was needed to lift the barrel due to it's easy-to-use shape and the extra power.
