Happy World Puppetry Day! From our learn system to our Circuit Playground video series, we show puppets love!
Read more about the history of the holiday, as well as specific details for this year’s celebrations from Puppeteers of America.
wpnsmith shared this project on Instructables! With more details here https://github.com/jervine/rpi-temp-humid-monitor
Over the past summer, my vacation home had a small water leak for three months, and I realized that had I been measuring the humidity in the effected area, I’d have
seen it go to 100% for a long time and I could have dispatched someone to fix the small problem before it became a big one.
And since I’ve been playing with Raspberry Pi computers for a while now, and saw an inexpensive temperature/humidity sensor on AdaFruit, I had all the pieces I needed
to implement an inexpensive network-connected monitor.
The Bill Of Materials (BOM):
1) Raspberry Pi Model B
2) Case
3) SD Card
4) Temperature/Humidity sensor
5 ) Power Supply (I use PoE splitters, but any 5V 1A Micro-USB supply will work)
Justin deployed a big update to the maps block in an Adafruit IO Dashboard. Here are all of the many things added:
There is now many more available options to help authors make unique FAQ or collapsible elements on the Adafruit Learning System. Sheehan just deployed a fun update to help make guides even better.
From Tyeth: Brents recent work on bringing the Feather Huzzah ESP8266 back online in WipperSnapper has been released this week, in version 1.0.0-beta.124.
Also recently in beta 123, support for the Sensirion SGP41 
was added, providing VOC/NOx index with an onboard SHT4x for it’s reference temperature and humidity.
On a side note, Loren on the Adafruit IO team came up with this great tool (ProtoMQ) to help us test protobuf changes before the IO MQTT broker (server) is upgraded. It hosts a test mqtt broker, and allows easy importing of proto files, along with auto-responding to client messages (configurable) with a nice web UI.
We’ve been hammering on it while building V2 of WipperSnapper, and it’s so useful that I wanted to call it out for anyone who might need such a tool (even though it’s not finished / perfect yet). Have a look at this PR for the recent changes: https://github.com/lorennorman/protomq/pull/4

Blurry Analog Clock
The Blurry Analog Clock by the Ruiz Brothers is a beautiful, dreamy take on keeping time. Powered by an Adafruit MatrixPortal S3 and a 32×32 RGB LED matrix, the clock displays hour and minute hands over a softly animated, flowing gradient. The background palettes transition automatically throughout the day and shifting from morning hues to a twinkling, starry night sky. Placed behind a 3D-printed diffuser panel, the clock gives off a thick resin-art aesthetic that makes a calming desk piece or wall accent.

No-Code Snowfall Tracker
Prepare for winter weather without writing a single line of code! The No-Code Snowfall Tracker by Tyler Cooper uses an Adafruit QT Py ESP32-S2 and a 4-digit 7-segment display to create a glanceable desktop weather monitor. By leveraging WipperSnapper firmware and Adafruit IO cloud actions, the device automatically pulls daily forecast data. The onboard LED glows blue when it’s actively snowing, and the screen displays exactly how many inches of snow to expect.
Winter weather can be unpredictable, especially when you’re trying to decide if it’s time to break out the shovel or if you can wait another hour. This project creates a simple, glanceable desktop display that monitors real-time snowfall and daily forecasts using a no-code approach.
By combining an ESP32 QT Py with a 7-segment display, you can keep an eye on the accumulation without having to check your phone or a weather app every ten minutes. The built-in NeoPixel on the QT Py acts as a visual alert, glowing blue when it’s actively snowing, while the LED matrix shows exactly how many inches of snow are expected for the day.
Using WipperSnapper firmware and Adafruit IO Actions, this guide will show you how to link cloud-based weather data to your hardware in minutes. All without writing a single line of code.

This is a remix of a Minecraft-style Easter egg redesigned as a spiral fidget toy. The model prints as two separate parts on the same build plate, allowing the spiral mechanism to spin freely once the print is finished. No assembly is required if printed together.
The spiral structure creates a satisfying fidget motion, making it both a decorative Easter item and a small desk toy.

Alex Alemi thinks slide rules rule and is rather enamored with them. Alex has collected several over the years. A favorite is an old Soviet KL-1 (above).
Unlike a pocket calculator, it feels like using a slide rule helps you develop a better number sense, rather than rob you of one. An elegant weapon for a more civilized age.
In order to ensure that I always have a slide rule at my disposal, I recently build a digital one, available at sliderule.alexalemi.com.
If you’d like to learn more about slide rules, you can download a PDF copy of Alex’ Zine that you can print and fold yourself. If you want to learn more, there is an old book by Isaac Asimov, or a great 1957 Educational film.
Read more in the post here.
Editor’s note: I learned slide rule in high school electronics class where the classroom had a large yellow two meter model above the blackboard. I bought a beautiful model, bambu with ivory (?) overlay with a leather case from my teacher. I had it until VCF Midwest in September where I sold it to someone that might use it more than me.

Alexander Tsidaev posts a minimalist tester for 4116 dynamic RAM chips.
No relays, protection resistors, or control buttons. Built with point-to-point wiring; +12 V and −5 V are supplied by inexpensive DC-DC modules. Pinout allows connecting socket pins 2–6 directly to Arduino board holes.
Two output modes: LCD display or serial console. Without a display, status can be read from the board LEDs: steady on — chip OK, five short blinks — fault.
Aimed at quick chip verification without elaborate assembly or an enclosure.

Seth Kushniryk has been porting MS-DOS 2.0 to the Apple IIe using the AD8088 Plus coprocessor card. It’s an 8088 CPU on an expansion card with its own RAM and ROM. The card shipped with CP/M-86, available from nanja.info.
The original ALF advertising materials suggest there may have been an MS-DOS port at some point (they write about it in future tense, so I don’t know if it ever actually happened), but the original OS disks aren’t shared to any of the usual places. I decided to start my own port because I like directories and object-oriented Turbo Pascal, neither of which CP/M-86 supports. Today I got it to boot.
The Apple II bridge loads IO.SYS and MSDOS.SYS into 8088 RAM, then hands off to the 8088. The BIOS reads the BPB from the disk image boot sector, SYSINIT prints the copyright, COMMAND.COM loads and prompts for the date and time.

On NPR’s Planet Money they dive into the growing world of robot chefs and what they mean for the restaurant industry. In a head to head competition a wok-bot goes against an award winning [human] chef with 13 years of experience. Along the way they explore the economic forces of robots in the industry: who are the winners and losers when robots come for the jobs?
Automation has changed many industries. But automation only started entering restaurant kitchens in the past couple decades. Which raises the question – what will robots mean for the restaurant industry? How will automation change jobs and how will it change the very food we eat?

Mathematicians rejoice, this is your day, 
-day is here. We hope you aren’t irrationally excited but 3.14 only rolls around once a year.
From the American Mathematical Society:
The holiday honors a special number: “Pi,” which is pronounced just like “pie”. Pi is an infinite, non-repeating decimal, so it’s usually abbreviated to 3.14, hence we celebrate it on March 14! Mathematics represents pi with this symbol: .
What does the number mean? For every circle, its distance around (circumference) is always a little more than three times its widest distance across (diameter). When you divide the circumference by the diameter, you get this fascinating number that has no end: 3.1415926535897932384… Indeed, computers have calculated pi to 105 trillion places (and counting) and have found no repeating sequences. As the ratio of a circle’s circumference to its diameter, is irrational and transcendental—qualities sure to bring a twinkle to any mathematician’s eyes.

If you want to jump in fast into crafting an electronic project, without needing to solder or even just a breadboard, Pimoroni’s Inventor 2350 W gives you a ‘bento box’ of delicious popular treats with a Pico 2 W already built in for instant gratification.
The Inventor is a multi-talented board that does (almost) everything you might want a robot, prop or other mechanical thing to do. Drive a couple of standard motors (or fancy motors with encoders)? Yep! Add up to six servos? Sure? Attach a little speaker so you can make noise? No problem! It’s also got a battery connector, so you can power your inventions from AA/AAA or LiPo batteries, and carry your miniature automaton/animated top hat/treasure chest that growls at your enemies around with you, untethered.
You also get a ton of options for hooking up sensors and other gubbins – there’s two Qw/ST connectors for attaching breakouts, three ADC pins for adding analog sensors, photoresistors and such, and three spare digital GPIO you could use for LEDs, buttons or digital sensors. Speaking of LEDs, we’ve also somehow managed to fit in 12 addressable LEDs (AKA Neopixels) – one for each servo and GPIO/ADC channel (or just use the whole lot for making rainbows, that’s fine too).
Best of all though, is the brains of the outfit – the onboard Raspberry Pi Pico 2 W, which will give your creations 2.4GHz wireless connectivity. Use it to trigger your mechanical friends to do their thing remotely, or hook your robotic canary up to an API and report the air quality in your neighbourhood.
Since it uses Pico 2 W and RP2350 as the base board, there’s plenty of support for programming it in Arduino, Pico SDK, MicroPython, CircuitPython, or anything else that the Pico 2 W can wrangle!

Andrew Back posts about restoring a vintage Sun SPARCstation IPX workstation.
If you worked in computing in the early 1990s, studied computer science around then, or just had a keen interest in computers, the chances are that Sun Microsystems was a familiar name and their workstations were highly coveted.
At this time PCs were fast becoming the standard desktop computer and pretty much all looked the same, while if you worked in a creative industry you might have been lucky enough to use a Mac — but even then, the differences were not so profound
However, there was a breed of computer that really stood out from the rest and not only looked far more exotic, but had a clear lead in terms of performance and capabilities — the UNIX workstation.
While most people were running Windows 3.x and being frustrated at the limited resources, lack of true multitasking and all too frequent instability, UNIX workstations provided a far more advanced, feature rich and robust environment. This included proper multitasking and typically greater RAM, more powerful CPU and advanced graphics, plus higher performance disks etc. Of course, this all came at a cost and a UNIX workstation could easily have a price tag 10x that of a typical PC.

An AI powered robot roaming through crowds of tourists. What could go wrong?!
Ok so Olaf isn’t fully autonomous but it is waddling in that direction. A new roaming snowman animatronic is coming to Disney World of Frozen in Paris and Tokyo. The AI in this instance is primarily focused on walking movement and heat management.
Learn more from Fast Company:
But building a weird skeleton is useless if it can’t walk. To nail the specific, goofy gait of the character, human coding simply wasn’t enough. Disney turned to reinforcement learning, an artificial intelligence technique that works like an evolutionary sandbox. In a virtual simulation, the software was fed the exact animation files from Walt Disney Animation Studios and tasked with figuring out how to fire the motors to balance the heavy head and match those movements without real-world Olaf face-planting every few steps. Through relentless trial and error, the AI discovered the precise mathematical inputs needed.

The Orbigator is an open-source, physical satellite tracker that turns complex orbital mechanics into a desk-side companion. It is powered by the Raspberry Pi Pico 2 and precision DYNAMIXEL servos, it physically points to the ISS (or any satellite) in real-time with zero drift.
Unlike traditional trackers that use static globes (requiring wire unwinding every orbit), the Orbigator features a rotating globe. This allows for smooth, continuous tracking across multiple revolutions without ever needing to reset or “unwind.”
The orbital mechanics are implemented directly in the hardware geometry (inclination angle). This ensures the satellite pointer maintains a true LVLH (Local Vertical, Local Horizontal) attitude throughout the entire pass—exactly how real satellites orient themselves.
Leveraging the 32-bit absolute resolvers in DYNAMIXEL XL330-M288-T motors, the system recovers its orientation instantly after power cycles. No homing, no limits, and no drift—just persistent, mathematical accuracy.
The Pico 2 is programmed in MicroPython.

We’ve gotten a few requests for alternatives to the popular TDK InvenSense ICS-43434, which just went into last-time-buy mode. We love this microphone ourselves because it’s an all-in-one I2S mic, so it works with a vast range of microcontrollers or microcomputers without needing a separate codec or I2C configuration.
Let’s find another I2S microphone, ideally with about the same footprint and 3V logic.

Today is International Women’s Day. While we celebrate Women’s History Month throughout March, today in particular we can celebrate the women in the world. Keep battling for equality.
International Women’s Day (IWD) has been around for over a hundred years, as have many of the issues still impacting women’s advancement. Since 1911, IWD belongs to all who care about gender equality. Celebrate women’s achievement. Raise awareness about discrimination. Take action to forge gender parity. All IWD activity is valid, that’s what makes IWD so inclusive.
Every year focuses on a theme and for 2026 the theme is Give to Gain:
Give To Gain emphasizes the power of reciprocity and support. When people, organizations, and communities give generously, opportunities and support for women increase. Giving is not a subtraction, it’s intentional multiplication. When women thrive, we all rise.
