In plain words

A floating Christmas tree displayed on a barge in Copenhagen's harbor during December features over 2,000 individually controlled RGB LEDs that create dynamic light patterns. The installation is towed to different locations around the harbor throughout the month, combining a traditional holiday symbol with custom engineering to manage power and stable anchoring. The project documents the technical process of creating the large-scale illuminated display.

    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://xlights.org/), but much less…
