Oh wait, we can make the gear flip with the backward
motion of the 1x16 blue beam right?

The arrow points in the direction that the blue • 1x16
brick is moved to
charge. At the end of this closest to the camera
there should be
rubberbands.
When the brick is almost back the small arm with • the

releases the rubberbandloaded brick and shoot it
forward.

That was the theory, I don't know if it will work
since I have not tested it
yet  :)

How about using a caster wheel? I used it for a
jumping mechanism, but I
think
it can also be adapted for a cannon like you
describe. Using 1 motor, it
keeps
firing over and over
