May 2020: Clocks are finished and ready for testing and calibration (and some tweeking).
The following describes some of the troubleshooting process that was required to make these clocks perform 'like clocks'. I expect them to run continuously, reliably, and accurately just like 'real' clocks.
Drive Module Modification
Replaced 8-cog drive wheel with larger 9-cog drive.
One track had to be completely replaced.
Controller/Drive board refinements
Transfer control components from breadboard to permanent chassis.
Run the clocks and watch for the following:
- Calibrate time.
- Catch any places in the track where the balls bind or bounce out.
- Make sure gears mesh continuously.
