Vintage Patinated Copper Victorian Phonautograph Seed Recorder

Construct the main body using mahogany hardwoods to create a sturdy, resonate internal chamber that protects the seed supply from moisture. The box is jointed with traditional finger joints for a classic Victorian aesthetic.

Fabricate the primary acoustic horn by hand-hammering a flat sheet of copper into a perfect conical shape. Apply a chemical patina solution to the surface to achieve an aged, weathered bronze aesthetic.

Install a miniature wooden stylus arm and a pivot mechanism that hangs over the seed basin. This non-functional, decorative element mimics the movement of early sound recording equipment while adding authentic period flair.

Assemble the final unit with brass hardware and mount it on a wall-bracket arm. Finish the wood with multiple layers of marine-grade spar varnish to ensure longevity against outdoor elements.
