This video demonstrates the first version of a Lego-based clock escapement mechanism regulated by a magnetically actuated balance wheel. The balance wheel is equipped with neodymium magnets mounted on opposing spokes. As the wheel oscillates, an extended arm periodically contacts the exit pallet, triggering the escape wheel to advance by one tooth. This interaction delivers a mechanical impulse back to the balance wheel, sustaining its motion.
The balance wheel reverses direction when the applied impulse exceeds its moment of inertia. During each reversal, the moving magnets on the wheel elastically interact with two stationary neodymium magnets positioned on either side. This magnetic repulsion provides a restoring force that maintains oscillatory behavior.
The cycle continues until the gravitational driving weight reaches its lowest position, at which point the system ceases operation. This setup illustrates fundamental principles of mechanical timing, impulse transfer, and magnetic feedback using modular Lego components.
