Vintage Patinated Copper Victorian Camera Obscura Seed Projector

Construct the main chamber using reclaimed walnut planks, carefully mitered to form a tapered, boxy frame reminiscent of early photography equipment. Incorporate a small, brass-rimmed aperture on one side to mimic the lens mechanism of an antique camera.

Fashion the roof from hand-beaten sheet copper, treating it with a vinegar and salt solution to achieve an authentic verdigris patina. This protective canopy will feature decorative scrolling brackets that extend slightly over the seed tray to keep the contents dry.

Install a removable cedar platform at the base of the chamber, equipped with drainage holes to keep birdseed fresh during rain. The tray should be secured with a sliding dovetail joint, allowing for easy cleaning and maintenance between refills.

Add the finishing touch by mounting a small, decorative glass prism atop the copper roof, capturing light to cast subtle reflections. Mount the entire unit on a turned mahogany post to complete the aesthetic of an early scientific instrument placed within your backyard.
