On the Adafruit boards, Colecago posts a spin on the LED star tree topper utilizing an ESP32 microcontroller and Adafruit DotStar multicolored LEDs.  From the weblog publish:

This 12 months I made a decision to make a Christmas tree topper for my spouse as Christmas is her favourite vacation. It concerned designing a small circuit board for the LEDs, reflowing the LEDs in a toaster oven, designing and printing the topper, writing code for an ESP32 to drive the LEDs, and making a small web site to simply management the lighted topper.

To start out with, I needed to make use of some new LEDs I hadn’t used earlier than. The APA102 LEDs (also referred to as Dotstar) are a bit of extra forgiving on timing than the usual Neopixel LED. I bought the LEDs and a breakout board from Adafruit. Sadly I didn’t just like the structure of the board because it had just one energy and one floor connection which was not conducive to a number of LEDs as I’d should share connections. I designed my very own board with four connections on either side

A number of the stunning animations:
