All very well, but he failed to explain the most essential part in this video ...how does he time the fall of the next ball to exactly one minute?

Is the motor regulated?

When he's showing the workings of the clock, the 1st ball is picked up at 1.28. The next ball is picked up at 2.19. So.....? Otherwise, very cool.

Taken from the info below the video...

For those that have noticed, no 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.
