Redo the double pendulum experiment with better and newer hardware.

• Use an air track to get oscillating masses instead of pendulum (or some kind of “air” bearing) (to reduce friction).
• Measure position/velocity  wirelessly (so no friction), or with a permanently mounted webcam with image processing software.
• Put everything together in a robust and easy-to-use package.

This project combines, mechanical, electrical (maybe) and computer work.
