It may smell great, but that freshly cut Christmas tree in your living room can be a real fire hazard if you don’t water it regularly. But a dried tree engulfed in an inferno of flames seems almost certain to be next to this digital Christmas tree, which spins a strip of blinking LEDs at frightening speeds to create a neat holographic effect.

It’s another creation of hardware hacker Sean Hodgins, who always seems to get extra inspiration around the holidays. In years past, Hodgins has created tiny TV ornaments that actually play retro Christmas commercials, but this year he’s upped the ante with a tree that’s easy to decorate and even easier to store the rest of the year. Unfortunately, it’s also very scary and prone to breaking during construction.

Dangerously fast spinning holographic Christmas tree

Through some trial and error, which included failed bearings, an overly wobbly support frame, and a burned out motor that had to be replaced with a half-horsepower AC motor, Hodgins finally got the “tree’s” simple triangular metal frame to spin at high speed rotate This allowed the persistence of vision effect to work properly. But the wind resistance of the square metal tube used to build the tree meant the whole thing had to be shortened to just 5 feet tall so the motor would have enough power to turn it fast enough.

A Raspberry Pi is used to power the LED strip, which flashes to produce images based on input from a static Hall effect sensor that detects a magnet attached to the top of the spinning tree . Animations are created by filling a folder with consecutive still images, and while the resolution of the LED strip is relatively low, the pixelated effect of the decorated tree is a big part of its charm. It definitely looks chopped together, and the safest way to huddle around it to sing Christmas carols is behind a pane of bulletproof glass, but at least you don’t have to lug it to the curb when New Year’s Eve rolls around.
