Vintage Patinated Copper Victorian Telegraphic Sphygmograph Seed Pulse-Recorder

Construct the main housing using mahogany planks joined with traditional box joints for a classic Victorian aesthetic. Incorporate a delicate brass armature that pivots on miniature ball bearings to simulate the movement of a mechanical pulse-recorder.

Fashion the roof from thin-gauge copper sheet, applying a chemical aging solution to achieve a rich, turquoise-green patina. Emboss decorative filigree along the eaves to match the elaborate diagnostic tools of the era.

Develop the internal seed reservoir with an adjustable gate valve that utilizes a weighted counter-balance system. This ensures that the bird's weight, once landed, releases a measured amount of seeds onto the feeding platform.

Mount the assembly on a stylized iron tripod base and finish all woodwork with a deep shellac polish. Add a small etched brass plaque to the front to identify the device as a legitimate scientific instrument for avian health tracking.
