Show HN: Mini Christmas Trees with addressable LEDs and RP2040-based controller Hello HN, these Mini Trees have a custom circuit board with WS2812 addressable LEDs on one side and a controller using an RP2040 microcontroller on the other, all inside a CNC'd Foamex PVC case. They stand around 23cm (9") tall. The firmware is written in MicroPython, which can be modified or replaced. Power is provided via USB-C, which is also used for programming. There is also a web-based animation sequencer to create lighting sequences in time to arbitrary audio, examples of which are on the linked page. This is similar to xLights ( https://bit.ly/3UrQW68 ), but much less powerful, and we hope to release firmware to interface directly with xLights soon. My colleague and I started kicking the idea for these around after making some custom circuit boards for another project, and thought we'd have a go at making smaller versions of some much larger exhibits we had made using 12 volt WS1812 bullet pixels. I hope you enjoy them, Merry Christmas! https://bit.ly/3UnriiZ December 2, 2022 at 01:20PM
