Posted in Misc Hacks Tagged basswood, engraved, esp32-C3, laser cutter, orrery, planetarium, zodiac Post navigation We’ve seen an orrery or two around here, executed in everything from solid brass to Lego, but this one really tickled our fancy. We love the look of this project the burnt edges and lightly smoked surface of the laser-cut wooden parts look fantastic, and the contrast with the brass wires is striking. The video below shows the “Planet Spinner” in action. An ESP32 C3 contacts a NASA feed once a day to get the relative positions of the planets and uses the zodiac disk to arrange everything nicely for the day. A zodiac disc sits atop the base and is the only driven element in the orrery every other celestial body moves thanks to a pin set into the zodiac disc. The layered base of the orrery, with pieces cut from a sheet of basswood using a laser cutter, contains a single tiny stepper motor and just two gears. The key to keeping this planetarium so petite while making it largely out of wood is to eschew the complex gear trains that usually bring the Music of the Spheres to life in such devices. But given that the whole thing is seriously in danger of being dwarfed by a USB-C connector, we’d say he’s got a pretty good shot at that record. We won’t take a position on that - such things are best left up to the good folks at Guinness. Claims to have made the world’s smallest wooden orrery.
