Vintage Patinated Copper Victorian Foucault Pendulum Seed Oscillator

Construct the main frame using weather-treated mahogany, incorporating a sturdy, central vertical mast to support the swinging pendulum arm. Ensure the wood is sanded smooth and finished with marine-grade varnish to withstand outdoor moisture.

Fashion the pendulum bob from sheet copper, etching intricate Victorian scrollwork into the surface before applying a chemical patina for an aged appearance. This heavy component serves as the mechanical weight that regulates the dispensing action.

Assemble the seed hopper using transparent acrylic sheets encased in a copper frame to provide a clear view of the reservoir levels. Design the base aperture with a gravity-fed sliding gate that opens slightly whenever the pendulum is disturbed by a bird.

Install the brass pivot assembly at the top of the mast, ensuring it moves with minimal friction to allow the pendulum to swing freely. Attach the final ornamental copper finials and secure the unit to a backyard post for an elegant, kinetic display.
