Day 201/16. Lightsaber - Repaired AND surprised.

In repairing a Lightsaber for a young knight, I was suprised by a few technical details.
1. Lightsabers rely on a supply of 2 x AA Duracell batteries (available presumably from the local market on Tatooine).
2. The complex electronics and power conversion from chemical reaction to pure light and sound is shrunken to an impressively tiny circuit board.
3. A shock however, was how haphazard and untidy the Jedi wiring is. The Battle Cruisers must be a nightmare to maintain.......
