The idea here is simple and lovely: a faceted star with translucent points around a central core, lit from within by addressable RGB LEDs, hanging and turning slowly in a dark room. That is the whole concept, and the execution behind it is serious work.
This took the maker a full year and a lot of CAD effort. The spikes are clear PETG, while the housing and inner cube are white ASA. An ESP32 with wired ethernet runs the whole thing, and a motor turns the star by way of a hanging shaft. The assembly hangs from a motorized enclosure mounted on an articulated boom.
Several details stand out to me. There are 24 spikes, each holding a single pixel that contains two LEDs. A slip ring carries electricity and data out to those spinning pixels, which is the part of the design I find most interesting. xLights drives the pixels along with the spin rate and spin direction, and a web UI handles configuration, including motor calibration and firmware updating. On weatherproofing, gasket tape plus external-only mounting hardware help keep the housing cavity dry, and that cavity ends up with an odd shape since the mounting hardware sits outside it.
There is still work ahead. The existing sequences need updating to include the new element, and a fresh sequence is planned for November. Beyond that, the maker hopes to build a second, larger star if time allows. Watching the colors move through purple, magenta, cyan, green and blue patterns while the star turns must look great in person, and I hope the bigger version happens.
