Below: Spring attached to a hair thin piece of Flexinol wire near the fulcrum point of the ship.

 

Below: Flexinol wire can be seen to the left of the mast. The ground wire is wrapped around the mast.

Below: Pic 12F675 in the center of the board. 5V regulator on the left side of the board, and Relay on the right side.

UPDATE!
The mechanism had to be repaired twice in the first 3 days. The first time the Flexinol broke near the crimp point. Looks like I had damaged it when crimping. Flexinol is very tough wire for it's size, but can still be cut easily if you are not careful. The second time, the wire carrying current to the flexinol broke near the crimp due stress fracture from constant flexing of the bare wire. This was fixed by wrapping with heat shrink to make sure that any flexing happened where the wire was insulated. Since then it has worked nonstop for weeks.
