Most Christmas tree ornaments are made of simple plastic, wood, or metal, and the most intelligent thing they do is shine light or play music. However, the developer, his Chris Bensen, World’s largest Raspberry Pi cluster (opens in new tab)created what could be the smartest ornament ever.
Shaped like Doctor Who’s Tardis time machine, the 3D-printed blue ornament contains a small Raspberry Pi cluster consisting of two Raspberry Pi Zeros, each powered by a USB power bank. will be The Pis connects to a blue LED light on top of the ornament and flashes just like the “real” Tardis when in motion.
You can see how Bensen created the ornament in the YouTube video embedded below.
In the video, Bensen shows how he assembled the ornament and lists the parts:
- 4x 3D printed parts
- 2x Raspberry Pi Zero
- 2x cylindrical USB power bank
- 1x blue LED light
- 1x 220 ohm resistor for LED
- 1x paper clip
- 4x M3 bolts
- 4x M3 threaded inserts
- 4x M2.5 threaded inserts
- 4x M2.5 button screws
- 2x microSD card for Rasberry Pis
- 2x microUSB to Type-A cable
Bensen too I posted the STL file For 3D printed parts.
Watch how Bensen puts the ornament together, solders some wires (the official parts list doesn’t have a name, but he probably has) to one GPIO on the Pi Zero, and connects it to a resistor and an LED. You can see. He puts both Pis into his 3D-printed insert, where he holds both of them and their power bank. Then insert the insert and close the whole.
The finished Tardis ornament looks great, but it doesn’t reveal the complexity of the computer that powers it. Bensen just shows it hanging in a tree with flashing LEDs. However, this is his cluster of two Linux computers, so it has more potential.
and Moderate post about the projectBensen writes:
according to Subject Moderate Post (opens in new tab) From Bensen, the world’s largest Raspberry Pi cluster. It debuted at Oracle Open World 2019 with a mix of 1050 of his Rasberry Pi 3B+ boards and uses Oracle Linux 9 as its OS. Run a Docker container on GraalVM running GraalPython.
Bensen now has a Pi Cluster in his garage that acts as a server. Also, two of his Arduinos are connected and the board runs a web service that enables the reset and power buttons and lights up some of his Neopixels.
So what do you think Bensen should do with Pi-powered ornaments? In our case, we set it up as a public web server that serves holiday greetings and allows users to remotely control a blue LED. To do. However, if they’re really Raspberry Pi Zeros and not Zero Ws, they don’t have network connectivity.
