Squeezable Fan #3DPrinting

Summer is quickly approaching. Don’t sweat in the subway, print a squeezable fan! Check out this cool design from GeorgeZSL shared via instructables

Let’s just admit it, all of the squeeze fans available are just toys. They are fun to play around for 5 minutes, but cannot really be used functionally. The wind is too little, the hand gets caught in the blades, and nowhere to grab. This is an upgraded larger version where you can actually use it to cool down!
I also narrowed down the tolerances of the original design to make the fan less wobbly, and the pins to fit more snug.

If spinning too fast, the cover may separate from the case since they are just held together by pins. Use superglue if necessary.
Please see the 2nd photo for instructions for putting together. There are 2 fan blades, choose whichever one you prefer. You may need to use a mallet to knock the pins into place.

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!

From the Adafruit Learning System Archives: Larson Scanner Shades (Trinket-Powered NeoPixel LED Strip Glasses)

Use this guide to make a simple cyberpunk/Tronpunk fashion project!

The Larson scanner is named after Glen Larson, producer of Knight Rider and the original Battlestar Galactica television series, both of which prominently featured the effect as the “eyes” of KITT, his nemesis KARR, and the Cylon Centurions.

Larson scanners were traditionally red (or yellow in KARR’s case), but thanks to the magic of NeoPixels you can change the software to use any colors you like.

This is a soldering project, albeit a small one. You will need the common soldering paraphernalia of a soldering iron, solder, wire (20 to 26 gauge, either stranded or solid) and tools for cutting and stripping wire.

You’ll need some method of securing the electronics inside the glasses. Hot-melt glue (with a glue gun) works well for this. Watch your fingers! Packing tape could also be used.

Check out the full guide in the Adafruit Learn system!

The History of ThinkPad

 

J.D. Hodges runs through the history of the ThinkPad. At one point, the ThinkPad was ubiquitous in office settings. The rugged laptop doesn’t get as much love as it used to, but it’s still going strong! Hodges makes great use of graphs, tables, and infographics!

 

ThinkPad has shipped continuously since October 1992 under two corporate owners (IBM 1992 to 2005, Lenovo 2005 to present), making it among the longest-running commercial laptop families on the market and unusually visually continuous from the 1992 700C to the 2026 P14s Gen 6. The 2005 IBM-to-Lenovo handoff did not rupture the brand the way skeptics expected: IBM’s ThinkPad engineering and design carried over largely intact, and Lenovo crossed 60 million ThinkPad units sold by 2010. The formula still has reasons to exist in 2026, when a 14-inch P14s Gen 6 AMD with 96 GB of DDR5 SODIMMs runs local 70-billion-parameter LLM workloads on a business chassis with a Copilot+ NPU and dedicated TrackPoint buttons.

A Curiously Minty Cyberdeck

Exercising Ingenuity built a cyberdeck in an Altoids tin using a Raspberry Pi Zero and shared the process in this video on YouTube.

Ugh, now we’re feeling nostalgic for Minty Boost and MENTA. Chris Young made Printy Boost to scratch that itch.

As far as cyberdecks go, we’ve also got our CYBERDECK Bonnet and CYBERDECK HAT for Raspberry Pi 400 & 500.

World Telecommunication & Information Society Day, May 17, 2026 #WTISD #DigitalLifeLines

The United Nations has designated May 17th  World Telecommunication & Information Society Day:

World Telecommunication and Information Society Day (WTISD) 2026 calls on governments, industry, and communities to strengthen the digital lifelines that keep the world running. Join us in designing the networks and systems that can withstand shocks and recover quickly, ensuring that no one is cut off and left offline when it matters most.

Celebrated every year on 17 May, World Telecommunication and Information Society Day (WTISD) highlights the growing role of digital technologies in our lives and commemorates the founding of the International Telecommunication Union (ITU) – the United Nations Agency for Digital Technologies.

The theme for 2026 is Digital Lifelines – Strengthening resilience in a connected world:

Resilience needs to be designed and included in every element of connectivity: submarine cables linking continents, terrestrial networks carrying data across cities, satellites supporting communication and navigation, and data centers powering digital services. When any part of this chain fails, essential systems, from finance and healthcare to transport and disaster response, are at risk.

From the Archives: MACROPAD Hotkeys

 

Learn how to turn your MACROPAD into the Hotkey wizard it was born to be; with Phillip Burgess on the Adafruit Learning System!

Press one of MACROPAD’s 12 keys to send a shortcut, function key or whole sequence of keystrokes to a connected computer. The OLED display provides a map, while LEDs under each key offer color-coded groups or themes. Turn the dial to select among different application sets.

This is one of those projects that you can simply find everyday use for as-is, or peer inside the code to see how CircuitPython makes this all pretty simple. Additionally, hotkey configuration files for different desktop applications are easily created, modified and shared.

See the full guide!
