Don Secretly Dreamed of Building a Time Machine
November 3, 2003
Weary of the varying time loss and gain of his mantle clock despite ongoing corrective measures, Don set out to modernize its time base-but added to the challenge by trying not to alter its original workings. His nonintrusive design employs the primary and core of a low-power filament transformer to generate a pulsed magnetic field that synchronizes the pendulum to the clock's original quartz timing source.
