Zach Burhop’s Trinket-powered piece is complete with 3D-printed ornaments and a custom LED star.
Two years later and Zach Burhop’s Christmas tree is still spreading some holiday cheer. Back in 2013, the industrial designer by day and Maker by night may have built one of the most geeked-out decorations of all-time. And with December 25th quickly approaching, we figured what better time to reminisce about the amazing tinyAVR-powered piece — complete with 3D-printed ornaments and a custom LED star.
“I was very disappointed in what you can buy — mostly just classical decorations. I saw the ornaments and had started playing around with the LEDs and thought this would be an awesome mashup,” Burhop explained.
In terms of electronics, the engineer (who happens to be a huge Adafruit fan) had some NeoPixels and Trinkets (ATtiny85) lying around. A two-meter LED strip was driven by the tiny MCU, and ran through the center of the tree, fading out through the branches. Another Trinket was tasked with controlling the 3D-printed tree topper’s animations. He also picked up an AC brick at a local thrift store, which handled all of the necessary power requirements for the 120 or so lights.
What’s more, you’ll notice that Burhop selected a white tree, which proved to be the ideal backdrop for the flickering, addressable RGBs and colorful DIY ornaments. Trust us, you’ve got to see it in action.
