Back in 2018 I made a Christmas LED string display using two strings of fifty 5V RGB WS2811 led pixel modules (12mm LEDs) connected together to make a 6 meter 100 led string.
This year I modified the firmware to make the display slower with less “flashy” effects. This should be easier on the eye and a bit more refined.
I also fitted 3D printed bulb diffusers from an excellent design by keith204 on thingiverse (thing:3331268) These make the LEDs look great..
Here is the hex file.
