Vintage Patinated Copper Victorian Astrolabe Seed Navigator

Construct the central seed hopper using reclaimed mahogany carved into a dodecahedron shape. Drill precise circular ports on each face to allow multiple birds to feed simultaneously while maintaining a structural look.

Fabricate a series of interlocking rings from thin birch plywood, staining them to resemble aged brass or iron. These rings rotate around the central hopper, mimicking the celestial coordinate system of a Victorian-era astrolabe.

Apply thin, hand-hammered copper sheets to the roof and base, treating them with a patina solution to achieve an authentic oxidized teal finish. Secure the copper using small decorative brass tacks to reinforce the industrial aesthetic.

Mount the assembly on an ornate wrought-iron bracket to complete the scientific visual. Ensure the hopper lid features a weather-tight hinge to keep seeds dry during inclement weather.
