Here’s my latest creation. I named the piece Koh-i-Noor, which translates literally from Persian as “Mountain of Light”.
It uses qty720 WS2812B LED’s, ~30 per edge, and is a bit over 16" in diameter. The 400/800ns timing seems to be stable, and I have no complaints about the smoothness and frame rates. On the to-do list is mapping the edges and creating custom patterns.
BTW, the edges of a cuboctahedron form 4 hexagonal great circle rings, which makes LED layout much each easier (i.e. no forking or deadends). Other shapes with this feature include the octahedron (3 square great circle rings) and the icosidodecahedron (6 decagon rings).
Thank you. I’ve moved past reflective window film. The square faces are 1/8" thick acrylic 2-way mirrors from either TAP or Canal Plastics, and they’re pretty decent. I ran out of material for the triangle faces, so while I was waiting I temporarily used some dreg sheets from Amazon I had laying around; the’re quite a bit thinner, which you can see as funhouse warping.
Ideally there’s nothing really to maintain, the controller board is external, and it’s hermetically sealed from dust/dirt; just as long as some idiot doesn’t rip the cord out. Truthfully, I’m waiting to make sure it’s working totally fine before I finish sealing it up. If I did have to crack it open, 4 slices with a razor blade would open up a square face. On later iterations I might add some sort of hinge.
It is really cool to see one with some of the mirrors not in place, it’s hard to tell if you could insert your hand or not.
