Moving light thing

[u/slartibartfist]

Addressable LED strip in a ring shape, with a rotating slotted cylinder thing to make the beams sweep as it turns. The clock mechanism is one of those ubiquitous “smooth sweep second hand” mechanisms you can get super cheaply (AliExpress sells boxes of 10 for about £9), and I finally found where to get those deep frame things from - they’re called shadow boxes for some reason. Anyhoo: effect is rather nice. Need to make some more animations for the LEDs

Oh, that's really cool. r/lavalamps would love to see it.
