Engineering

It's weapon time in Engineering club.  Following instructions found on the Internet, Alain's team made a rapid fire Lego gun.  Although getting the electric motor to spin is easy to program, the clever bit is using different size cog-wheels to make a gear ratio so the firing mechanism spins a lot faster than the motor.  The ammo comes from a magazine that can be reloaded as often as needed.  I'll be back!
