LEGO Ball Clock

A custom working ball clock built entirely using LEGO parts. It is motorized, but uses a mechanical system of rails to display the time using balls, as described in the video.

These novelty clocks were invented in the 1970s by Harley Mayenschein. You can find more information about them here: http://www.idle-tyme.com/

For those that have noticed it does not keep accurate time in the video. I just wanted to show off the mechanical components of the clock. In the video it is running off of a standard LEGO 9V motor, which ends up picking up a ball every 55 seconds. In order to keep accurate time, an actual timing motor/controller has to be used. This could be easily done using the LEGO mindstorms system.
