Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

A fully articulated spooky spider that can dangle from a web of filament. Print-in-place, no assembly required. Includes a 3MF with all parts, plus optional separate-eye printing (no MMU/AMS needed) for a two-color look. Test-fit one leg set before committing to the full print.

Michał Zalewski on the lcamtuf’s thing blog says when working on the book, The Secret Life of Circuits, he wanted to keep the artwork real.
My beef with the diagrams in popular electronics textbooks and online tutorials is that most of them are fake. At best, they’re retraced from ancient texts; at worst, they’re sketched from memory and can be charitably described as “inspired by true events”.
The Secret Life of Circuits contains about 290 original illustrations and does its best to avoid such shenanigans. I painstakingly gathered real data for everything from quartz crystal frequency response, to battery discharge curves, to signal reflections in a 100 ft run of coax cable strewn around the workshop, to the behavior of vacuum tubes.
See how real-world measurements differed from the pretty textbook diagrams in the post here.
Random Nerd Tutorials shows how to establish a bidirectional Bluetooth Low Energy (BLE) communication between a Raspberry Pi and a Raspberry Pi Pico.
The Raspberry Pi Pico will be set as a BLE peripheral with two characteristics. The Raspberry Pi will read and write to those characteristics, establishing a bidirectional communication.
For the Raspberry Pi Python program, we’ll use the
bleaklibrary, and for the Pico MicroPython program, we’ll use theaioblelibrary.

Doom is a video game made by id Software that released in 1993. It was a revolution in gaming that spread across the world and defined the modern FPS. Its popularity has given rise to the saying “Doom can run on anything”. To prove this point Doom has been ported to almost everything, from microcontrollers, to toasters, and even bacteria.
Armaan Gomes and Liam successfully ran (crawled) Doom on a CPU built from scratch (and then posted a video that got a few million views).
To be honest, I still can’t believe it. What did we really do though? Well, we designed a custom CPU at the logic gate level, connected it to peripherals, adapted the DOOM source code to run on our machine, and deployed it onto an FPGA to run in real time. Before running Doom, we had only run simple programs that we had written, like Pong and Mandelbrot sets. Now we can run full published games, but getting here was a rather rocky road.

Ben Krasnow on the Applied Science YouTube Channel posts about seeing inside insects with an electron microscope and a femtosecond laser.
I use a femtosecond laser like a lightsaber to cross section insects and inspect them with an electron microscope. What’s really inside an insect’s head?
