Sean Hodgins’ video-playing Christmas ornament
Standard Christmas tree ornaments are just so boring, always hanging there doing nothing. Yawn! Lucky for us, Sean Hodgins has created an ornament that plays classic nineties Christmas adverts, because of nostalgia.
Sean first 3D printed a small CRT-shaped ornament resembling the family television set in The Simpsons. He then got to work on the rest of the components.
The ornament uses a Raspberry Pi Zero W, 2.2″ TFT LCD screen, Mono Amp, LiPo battery, and speaker, plus the usual peripherals. Sean purposely assembled it with jumper wires and tape, so that he can reuse the components for another project after the festive season.
By adding header pins to a PowerBoost 1000 LiPo charger, Sean was able to connect a switch to control the Pi’s power usage. This method is handy if you want to seal your Pi in a casing that blocks access to the power leads. From there, jumper wires connect the audio amplifier, LCD screen, and PowerBoost to the Zero W.
Then, with Raspbian installed to an SD card and SSH enabled on the Zero W, Sean got the screen to work. The type of screen he used has both SPI and FBTFT enabled. And his next step was to set up the audio functionality with the help of an Adafruit tutorial.
For video playback, Sean installed mplayer before writing a program to extract video content from YouTube*. Once extracted, the video files are saved to the Raspberry Pi, allowing for seamless playback on the screen.
When fully assembled, the entire build fit snugly within the 3D-printed television set. And as a final touch, Sean added the cut-out lens of a rectangular magnifying glass to give the display the look of a curved CRT screen.
Then finally, the ornament hangs perfectly on the Christmas tree, up and running and spreading nostalgic warmth.

Have you created Raspberry Pi tree ornaments? Maybe you’ve 3D printed some of our own? We’d love to see what you’re doing with a Raspberry Pi this festive season, so make sure to share your projects with us, either in the comments below or via our social media channels.
*At this point, I should note that we don’t support the extraction of video content from YouTube for your own use if you do not have the right permissions. However, since Sean’s device can play back any video, we think it would look great on your tree showing your own family videos from previous years. So, y’know, be good, be legal, and be festive.
Very neat. Funny to think how impossible such a gadget would have seemed back in the nineties, and yet now it’s create-able from off-the-shelf parts :-) (apart from the 3D-printed case)
Very cute. Looks like a fun project.
We’ll be making festive ornaments at Manchester Raspberry Jam — I think it’s a sell out, so if you haven’t already got a ticket you can follow along @McrRaspJam
