Trimming one’s Christmas tree can be an enjoyable tradition year after year, but every once in a while some variation on the established order can be just as fun. Seeking some new ornaments to and desiring to flex his skills, Instrucables user [Gosse Adema] created a LED-illuminated, phone-controlled, deltrahedron Christmas tree ornaments.
Wemos DI Mini Pros are the brains of these little guys, WS2182b RGB LED strips — being the superb go-to’s that they are — light the ornament, and a 5 V power supply keep them lit. [Adema] used the Wemos specifically to create a web server unique to each ornament, and goes into incredible detail on how to program each one — now there’s an arrangement of words you wouldn’t expect to see — providing all the code he used, as well as the models to 3D print the deltahedron.
[Adema] also provides steps for a non-wireless version in case pulling out all the stops isn’t practical. Don’t forget to decorate the final product!
While this is indeed a merry hedron, one could go the route of a foul-mouthed decoration instead for your custom ornaments.
