This is a concept to working prop, end-to-end tutorial or as they say in commercials for a popular Italian, tomato-based sauce, “It’s in there.”

I built a large 4’x16′ pixel matrix using Chroma Mesh from Boscoyo and 1,024 5V pixels. I show how to model this in xLights to get the wiring plan and I built is as a single string of lights using one controller connection. This requires a lot of power injection. but it’s pretty easy to do on a matrix.
Finishing up preps on the sticks, I encountered a perfect power injection example. I also created a cable snake for the line from the controller to the first pixel.
I had planned on replacing the pixels in the wreath prior to the season last year, but ran out of time. The wreath made that a priority this year. The video includes a power injection demo.
