This tree design is based on the tree featured here: https://hackaday.io/project/18821-ws2812-christmas-tree
My plan was to cut the tree out on my CNC machine using a single fluted endmill. After shattering a couple of sheets of acrylic this idea was abandoned. The design file was sent to https://www.ponoko.com/ for laser cutting. The design fits into a P1 sheet and was cut using 0.118 inch clear acrylic. Here is the design file that can be uploaded to be cut: https://github.com/mdunakin/Ws2812bChristmasTree/blob/master/Design/tree5.svg
The code is just a configured version of the FastLED DemoReel1000 example code. It can be found here: https://github.com/mdunakin/Ws2812bChristmasTree
Construction was not super complex. The two tree pieces were hot glued together. The led rings were attached from smallest to largest. When the ring was attached it was wired with 30 awg wire wrap wires. The ground and vcc on the rings were connected together. The data out on the rings was connected to the next rings data in. As a small side note these wire strippers are amazing if you want to strip wire wrap wire https://amzn.to/2SaPNAG
Here is a picture of the constructed tree:
Here is a video. The tree looks much better in real life.
