This is the Arts and Crafts part of the project! The design shown here is just one of many possibilities. How you approach it will depend on your goals and available tools and materials.
Initially I’d planned to hang the strips from a curtain rod with the electronics exposed on a board above the doorway. After encountering some durability issues, all the hardware was instead moved into a wooden box with top and bottom open for ventilation. It looks a lot nicer with all the strip-hanging hardware and wiring hidden away…just a single power cord protrudes.
I don’t have plans for this box. It’s a simple shape that was improvised, with few measurements.
All those strips weigh a lot. About 5 pounds total. A beefy 1" wooden dowel replaced the (now pretzel-shaped) flimsy adjustable metal rod. Holders at the sides allow the dowel to be lifted out for access to strips.
Rings cut from PVC pipe keep the strips uniformly spaced. It was quicker than 3D printing.
Experimenting with placement, it looked like everything might simply fit on the rear board…
Here’s most of the parts fastened to the board. The 12-gauge power wires have been trimmed to length and are held with cable clips…
