Stillsuit anyone? Not quite, but engineers at the University of Texas have developed a jacket that collects water from the air. The advance fabric technology can harvest 3x-10x more water than current materials. Via UT News:

“The important advance here is that the team did not simply make another material that absorbs water,” said Keith Johnston, co-author and chair professor of the Cockrell School of Engineering’s McKetta Department of Chemical Engineering. “They designed a pathway for water to move quickly, from vapor in the air, to liquid on the fiber surface, and then into the textile. That transport design is what allows the material to work not just in a small lab test, but in a wearable system.”

Once upon a time in Europe, television remote controls had a magic teletext button. Years before the internet stole into homes, pressing that button brought up teletext digital information services with hundreds of constantly updated pages. Stephen Cass writing for IEEE Spectrum writes about reviving teletext ssing a computer’s sound card.

I decided to send the teletext using the AX.25 protocol, which encodes ones and zeros as audible tones. For VHF and UHF transmissions at a rate of 1,200 baud, it would take 11 seconds to send one teletext screen. Over HF bands, AX.25 data is normally sent at 300 baud, which would result in a still-acceptable 44 seconds per screen.

When a teletext page is sent repeatedly, any missed or corrupted rows are filled in with new ones. So in a little over 2 minutes, I could send a screen three times over HF, and the receiver would automatically combine the data. I also wanted to build the system in Python for portability, with an editor for creating pages, an AX.25 encoder and decoder, and a monitor for displaying received images.

See how things were built and the results in the article here.

Cosmodial is an open source star atlas that runs in your browser. Select your location and look up! I especially like the red filter mode to keep your night eyes sharp. via KilledByAPixel on GitHub:

Ever look up and wonder “wait, is that a planet or just a really bright star?”

Cosmodial knows. Tell it where you are and it paints the actual sky above your head, live! The Milky Way drifting overhead, the horizon glowing at dusk, planets show up exactly where they really are. Drag to look around, zoom from a wide view all the way down to a telescopic eyepiece view where Saturn’s rings resolve.

Art of the problem gave a super simple bot a pretty big brain. The two legged GrowBot is based on a Raspberry Pi Zero 2, two servos, a camera, an IMU, a battery, some 3D printed parts.

This project started when I imagined making a little robot that would learn everything, how to move and do things. A pure machine learning approach, using basic evolutionary algorithms and then a neural network. It then evolved to ask, “what if you gave a modern AI foundation model a nervous and motor system?” GrowBot collides these questions into a “general learning robot”, which can be anything… and learns to move, see, and react from scratch.

Ben Hardill writes on Ben’s Place about how to configure a Raspberry Pi 4, 5 and Pi Zero to act as a USB Ethernet device for a while now. Starting with Pi Zero in 2017, then Pi 4 and finally for Pi 5 in 2023, used Raspberry Pis configured this way for lots of different things both at home and work.

I noticed a link to the Raspberry Pi Blog that talks about how USB Gadget Mode been added to the default Raspberry Pi OS Trixie version as of January 2026 and can be enabled via the new version of the Raspberry Pi Imager.

See how it’s all done in the post here.

Marko Stanic‘s goal was to build a complete, shippable first-person shooter using techniques that were common in the early 90s, while using a modern compiler and a platform abstraction layer.

I expect to publish Catlantean 3D sometime in Q1 2027. Right now, I’m focusing on level design, adding some more enemies and weapons, and polishing as I go.

I’m aiming for somewhere in $5-$8 price range. I intend to release the game source code on GitHub as open-source, but you’d have to buy the game to get the actual data archive (with graphics, levels, sounds, music, etc.), which I think is fair.

Check out all the details on how the game will be built in the post here.

Ken Shirriff is back with vintage hardware, this time an IBM 604, an electronic calculator from 1948.

1948 was an interesting time for computing. For decades, businesses had used punch card equipment that added and sorted electromechanically. Now these electromechanical relays and counting wheels were being used to build room-filling general-purpose computers such as Harvard Mark I (1944) and IBM’s SSEC (1948).

But slow electromechanical mechanisms were already becoming obsolete. World War II had fostered the development of electronics and vacuum tubes for radio, radar, and navigation. Electronic technology was being used in massive electronic computers, such as Colossus (1943) and ENIAC (1946). The first stored-program computer, the Manchester Baby, was built in 1948.

In the midst of these technological advances, IBM introduced the Electronic Calculating Punch, type 604.1 This system may seem like a step backward: it wasn’t a computer, but a programmable calculator that performed a fixed set of operations. However, it was much smaller3 than a computer—about the size of a double refrigerator—and much cheaper: renting for $550 a month, it was affordable by businesses and universities.

Since it used vacuum tubes, it was much more powerful than electromechanical equipment; it could do 60 operations in under a second, including multiplication and division. As a result, the IBM 604 became very popular, with over 5600 units produced. Moreover, IBM’s experience with electronics in the 604 led to the success of its vacuum-tube computers in the 1950s.

See the video below and much more in the post here.

Floating point arithmetic is a crucial part of modern computing. A large proportion of the silicon currently being installed consists of ‘floating point units’ and floating point standards continue to emerge to meet the needs of modern machine learning.

But where did floating point arithmetic come from and where was it first implemented? Perhaps surprisingly it can trace its beginnings to the origins of the development of the computing universe as we know it today ….

The Chip Letter does a deep dive.

Amstrad CPC 464 / 664 / 6128 emulator for the Raspberry Pi Pico 2 (RP2350). HDMI, VGA, and composite-TV output. SD card file browser.

PS/2 keyboard, NES/SNES gamepads, optional USB HID (keyboard, gamepad, XInput). Disk (.DSK, .IPF), tape (.CDT), and cartridge (.CPR) loading. Audio over HDMI, I2S, or PWM.

Based on Caprice32 by Ulrich Doewich, with the cpc4x adapter layer by Ulrich Cordes. IPF disk image support via the SPS Decoder Library (capsimg).

Code heritage: this project reuses code from several existing CPC emulators and Pico homebrew projects. Caprice32 provides the full emulation core (Z80, CRTC, Gate Array, AY PSG, FDC); cpc4x contributes the dialog and printer adapter layer. Platform drivers (HDMI, composite TV, PS/2, NES pad, USB HID) are adapted from open-source Pico projects — see the License section for full attribution.

The Open Repair Data Standard (ORDS) defines a shared approach towards collecting and sharing repair data about small electricals and electronics. The goal of this standard is to make it easy to combine open data on electronics repair that has been collected by many different groups.

Following a common standard helps us to identify trends and patterns globally, and also within countries and regions, by combining data from local community repair events.  For example, when we combine our data, we could identify the most recurrent failures and fixes of blenders brought to community repair events in the UK, across Europe and even globally.

Summary

• The standard focuses on repairs of small electrical and electronic products.
• It focuses on collecting information about 3 main areas: Product Related; Repair Related; and Session Related.
• For each primary module, it explains what they are and identifies the data we collect for them.
• For each field, the standard explains how to collect data in ways that make it easy to aggregate and compare.
• Data collected is shared with an open Creative Commons license.

ntsc-rs is a video effect which emulates NTSC and VHS video artifacts. It can be used as an After Effects, Premiere, or OpenFX plugin, or as a standalone application.

Other popular effects eyeball the look of VHS tapes using simple color lookup tables and overlays. ntsc-rs uses algorithms that model how NTSC transmission and VHS encoding actually work, based on algorithms developed in composite-video-simulator, zhuker/ntsc, and ntscQT.

ntsc-rs is written in Rust, and is multithreaded and SIMD-accelerated. It can run in real time at much higher resolutions than actual NTSC footage.

See more on their website ntsc.rs and on GitHub. And try the web browser version (works best in Chrome desktop).

Kai Pereira debuts a folding, scissor lift, cross-cantilever 3D printer  made to demonstrate at Open Sauce 2026.

The finished project will essentially be a combination of two printers.

Last summer, I designed my own 3D printer motherboard, and it’s made me really antsy to design my own fold up printer! So; I’ve spent quite a few hours (and a day of skipping school) to come up with the exact type of fold up mechanism I want to do, alongside some other cool specs for it!

My process was fairly simple:

• I wanted to have a decent amount of bed area for if I brought it to hackathons and needed to print something a bit larger
• I wanted it to be able to fit inside of a filament box so it’s easy to transport
• Should be made using off-the-shelf parts, and the design shouldn’t be insanely overly complex.

After many hours, I came up with my brain-child! A folding, scissor lift, cross/double cantilever 3D printer.

See the details on GitHub, especially the planning journal.

Austin Z. Henley writes about automating a job away, inspired by conversations with several colleagues.

I was talking to a friend who runs a startup and he said that he tells his team, “don’t do anything three times.” If they have to do something more than twice, they should automate it.

Surely, this is overkill? I already automated 95% of my coding-related tasks. What else would be left for me to do even?

I started trying it. Slowly at first, because automation can be a distraction from getting work done in the moment. By the second week, I was leaning in head first—how deep does the rabbit hole go?

See what happens in the post here.

From the mail bag!

As a kid I was massively
enabled in my projects by Adafruit and hope what we are building allows
creators to take the next step in their projects and make custom circuits
that suit their needs.

Thanks!

The Rust Embassy Examples for Raspberry Pi Pico 2 contains examples for the Raspberry Pi Pico 2 (RP2350) board, written in Rust using the Embassy async framework.

There are several examples included including using Matter.

See GitHub for the details.

• Jab, Jab2D, Jab3D — simple motion burst detectors for 1, 2, or 3 axes.
• Shake, Shake2D, Shake3D — smooth motion energy tracking for vibration and shaking.
• Tilt and Roll — orientation signals from 9DoF IMU data.
• Tilt_Roll — fast roll/tilt computation using accelerometer data only.
• TouchArrayGestureDetector — brush/rub and swipe-style touch features for sensor arrays.
• Button — tap, double-tap, hold and press tracking from digital button input.
• utils/ — reusable helpers for smoothing, thresholds, mapping, timing, and sensor support.

This library is made for people who want meaningful sensor features, not raw numbers. Instead of reading raw acceleration or touch values, you can get:

• a jab intensity score
• shake energy that grows with movement and decays smoothly
• tilt and roll values ready for gesture use
• touch brush/rub metrics
• button interactions like taps and holds

Mechanize, Inc. is trying various LLM models to see how well they can make a Game Boy Advance emulator in Webassembly given various time constraints. Above are the May 2026 numbers.

Each model gets a Docker container with the Rust + wasm32 toolchain, the ABI specification, a BIOS stub, dev ROMs, and an oracle CLI, which is a black-box wrapper around Mesen2 that the model can run on any ROM with any input sequence to see Mesen2’s behavior. The model cannot read Mesen2’s source and does not have access to the internet. We run each model for 24 hours, and take checkpoints of its progress every 15 minutes.

According to their charts, Claude Opus 4.6 is the leader, beating other commercial models and hands down better than local models.

Ed note: I wonder how Fable and Mythos will do…

See the results at gbaeval.com and all the nitty gritty on GitHub.

Ben Siraphob is currently working on a reproducible Ghidra reverse-engineering project for the TI-84 Plus calculator OS (version 2.55MP), a Zilog Z80 system.

A Z80 (64 KiB address space) with hardware paging maps flash page 0 at 0000 (the kernel: RST vectors, the bcall dispatcher, FP/VAT/memory core) and swaps other 16 KiB flash pages into 4000 on demand. Code reaches routines on other pages via bcalls (rst 28h + a 2-byte ID resolved through a jump table on flash page 0x3B).

The OS is a single-tasking context machine: a main event loop runs the active context’s handlers, switching contexts by key. All arithmetic flows through a 9-byte BCD floating-point engine (OP1–OP6); named objects live in the VAT; TI-BASIC is stored as 1/2-byte tokens executed by the parser on page 0x38.

See a detailed outline of the reverse engineering here and the GitHub repo here.

gpusnek answers the question “What would it look like to be able to inline arbitrary Python code into your high-performance CUDA kernels, with no consideration for why that is a bad idea?”.

The repository implements a full Python interpreter that can run on one GPU thread (or in parallel on many). It even includes the Python lexer, parser and bytecode compiler.

We take the source code from MicroPython, ram it through nvcc (NVIDIA’s CUDA compiler), and fix most of the things which break.

Examples include:

• Running 1 Million Python interpreters on a consumer GPU and using them in an interactive REPL.
• Communicating between CUDA threads by using Python to read/write to a shared virtual filesystem living in VRAM
• Other such nonsense.

See it all on GitHub.

NEW PRODUCT – Snap-on Enclosure for Adafruit FeatherWing RP2040 Prop-Maker

Here is a cute and minimal enclosure for your Adafruit RP2040 Prop-Maker Feather with I2S Audio Amplifier to keep it safe during use and transport. This case has been custom-designed and 3D printed to accommodate the USB Type C main USB connector on one end, the terminal block on the other, STEMMA QT connector, and the Reset and Bootloader buttons. No screws or glue are required; simply snap the Feather into the bottom piece and assemble the top piece.

It’s made of translucent milky white plastic with an SLA process, so you can still easily see the NeoPixel and 5V power good LEDs shining through, and there are no lines or blobbiness to the print.

No boards, cables, or accessories are included. Designed for the Adafruit RP2040 Prop-Maker Feather with I2S Audio Amplifier, which you can grab here!

Socreates is a Socratic coding companion by Serge Zaitsev which reviews your code, challenges your decisions, but never writes code for you. A non-coding coding agent, really.

It’s made with ~1000 lines of Go with zero dependencies. It works with Ollama (local) or any OpenAI-compatible API (DeepSeek, OpenAI, OpenRouter).

See this MIT licensed project on GitHub.

Radu Motisan recently had to implement SDI-12 communication on a multi-parameter sensor. The PCB had an extension port on the PCB, exposing UART1 RX&TX and 2 GPIOs.

While I considered using the UART first, detecting the break was a bit problematic. So a different solution with bitbanging on one of the GPIO’s was implemented. Timing issues were critical and were solved using one of the AVR timers (Timer1).

The SDI-12 implementation on uRADMonitor CITY is entirely software-defined, requiring no additional hardware beyond the direct wire connection. On the ATmega1284P microcontroller running at 14.7456 MHz, the firmware uses a pin-change interrupt on GPIO1 to detect every signal transition, with Timer1 providing precise bit timing at 1200 baud.

See the video below and more here. The full source code is on GitHub.

Model F Labs has come out with customizable beam spring keyboards.

What is a Beam Spring Keyboard?  Before the Model F keyboard was the Beam Spring keyboard, a keyboard that was designed to be like the IBM Selectric electric typewriters but made to work with IBM’s mainframe terminals.

Originals regularly sell for over $1,000 to $2,000 but now you can get one in various “normal” modern layouts and various color options for a fraction of that cost.  The new beam spring keyboards are also compatible with MX keycaps (see below for details).

The B104 model is the standard 104-key layout similar to the classic Model M.  The BSSK model is similar to the IBM Space Saving Keyboard / 87-key / TKL style keyboards.  The B122 model is similar to the 122-key terminal keyboards but with LED lock lights and separated function blocks.  The B62 model is similar to the F62 / 60% layout keyboards.

There are customization options. See the extensive description in the listing here.

After more than 35 years, the HP 16c – the legendary programmer’s calculator – returns in a Collector’s Edition version. It preserves the intelligent design and power of the original model while introducing refined improvements for modern users.

Engineers, programmers, and enthusiasts will appreciate the same intuitive layout and advanced functionality, now with faster performance and enhanced programmability.

It retains the familiar RPN (Reverse Polish Notation) layout and design of the classic HP 16c but is now up to 100x faster.

It allows users to switch seamlessly between number bases (HEX, DEC, OCT, BIN) and to perform bitwise operations, logical tests, and integer arithmetic with customizable word size (1–64 bits). The new model also includes the ability to save and load programs – a valuable feature for professionals and collectors alike.

Oscar Molnar already had an RTX 4080. 16GB of VRAM. Good enough for gaming, not good enough for  LLM models Oscar wanted to run locally. The next step up in GPU land is either spend a fortune on a card with more VRAM, or find another way.

I found another way.

I bought a datacenter GPU that doesn’t even have a normal PCIe connector, stuck it in my gaming PC with an adapter, and now I have 32GB of VRAM across two GPUs running a 27 billion parameter model at 32 tokens per second. The whole thing cost me £200.

This is a Tesla V100 SXM2 16GB. It was designed for NVIDIA’s DGX servers and hyperscaler racks. The SXM2 form factor means it does not have a PCIe slot. It does not have display outputs. It does not have a normal power connector.

Turns out, someone makes an SXM2-to-PCIe adapter. It is not made by NVIDIA. It is not officially supported by anyone. It is a bare PCB with the SXM2 socket on one side and a PCIe edge connector on the other. I paid about £50 for it. Half of that might just be the copper.

Check out the build and how it does in the post here.

Lumafield looks inside four products from BYD:

BYD delivered 4.6 million vehicles in 2025, making it the world’s largest electric vehicle manufacturer by volume.

We got our hands on four components from BYD’s lineup and put them in our CT scanner: a lithium iron phosphate battery cell, a window switch panel, a portable EV charger, and a key fob. They reveal as much about the company as they do about what’s inside the parts.

See details and inside scans from multiple angles in the article here.

Chris Hanson writes about how AlphaPixel took a look at Amiga Juggler.

The Juggler animation was ground-breaking and Earth-shattering. Even the Amiga’s creators (Commodore) didn’t believe it had been made on an Amiga. They thought the actual computation work had been done on a mainframe, and the result simply converted to and displayed on an Amiga.

There were known references to the Juggler raytracer source.

For this archive I wanted a Python version that could be kept with the recovered files and run without compiling the original C program. Most developers have easy access to Python, and it’s quicker to run a one-off Python script than it is to spin up a dev environment, configure and compile and run a compiled native executable. Plus, the Python interpreter is easy and more harmless to modify and debug.

I contacted Eric Graham on February 10, 2026 and asked directly:

I was hoping to put the code onto GitHub for posterity, and I realized there is no explicit license, or copyright release on the code. I’m wondering if you’d be willing to specifically declare a license or a release of copyright so it would be legitimate on GitHub.

Eric replied the same day:

Yes, I’d be happy to! It is ironic to be most known for something that I did in a day! As far as I am concerned anyone can do what they want with the code, so long as I get a mention!

That clarifies things sufficiently. This code should be treated as public domain with an attribution request. The attribution is not hard to honor.

Chris’ repository for the extraction is on GitHub. Read more in the article here.

Dave Farquhar on The Silicon Underground writes about the rise and fall of the early PC clone company Eagle Computer.

When it comes to 80s computer brands, few flew as high as Eagle Computer flew in 1983. The aptly named company was selling 12,000 computers a month and had been doubling sales every quarter under the leadership of a talented CEO.

Eagle had been a leading producer of CP/M computers, entering the market somewhat accidentally. They were an offshoot of Audio Visual Labs, who made a product that could double as a general purpose computer. Audio Visual Labs recruited Dennis Barnhart, the vice president of marketing and sales at Commodore, in 1981. Audio Visual Labs spun Eagle off as a separate company soon after, and Barnhart became CEO.

Eagle was selling 12,000 units a month at its peak in 1983.

Then Eagle lost Dennis Barnhart, in a crashed Ferrari on the day of its IPO, June 8, 1983. In this blog post, we’ll explore the reasons Eagle Computer fell, because there was more to it than just the tragic story involving its CEO.

Automated License Plate Readers (ALPRs or LPRs) are AI-powered cameras that capture and analyze images of all passing vehicles, storing details like your car’s location, date, and time.

They also capture your car’s make, model, color, and identifying features such as dents, roof racks, and bumper stickers, often turning these into searchable data points.

These cameras collect data on millions of vehicles regardless of whether the driver is suspected of a crime. These systems are marketed as indispensable tools to fight crime, but they ignore the powerful tools police already have to track criminals, such as cell phone location data, creating a loophole that doesn’t require a warrant.

Flock Safety is one of the largest ALPR vendors in the United States. Their cameras are installed for police departments, businesses, and HOAs. Captured vehicle data is uploaded to Flock’s cloud system, where participating agencies can search and share information across jurisdictions.

DeFlock is an open-source project mapping license plate readers. There is an interactive map of Flock/ALPR cameras. DeFlock’s mission:

Our mission is simple: to shine a light on the widespread use of ALPR technology, raise awareness about the threats it poses to personal privacy and civil liberties, and empower the public to take action. ALPRs are increasingly being deployed by law enforcement and private companies without the public’s full understanding or consent, and they collect vast amounts of data on our movements, often without any real oversight.

NYPL staff said it best in this post discussing books targeted for censorship based on LGBTQ+ content:

Banning books is an attempt to silence voices. Voices that have fought to be heard. Voices whose stories light the way for the next generation. Voices that belong in libraries. Let us say it loud and clear: Libraries are for everyone and books are for everyone.

talk to your librarians about what other titles have been the target of censorship, then—check them out. Read banned books. Ensure these stories—and the writers who share them—are read, their voices amplified, and their impact felt.

Erich Styger in his latest research project is using the NXP FRDM-MCXN947 board.

As part of that project I have to collect and export application trace data for later analysis. In that project I’m using the the Tracealyzer product from Percepio.

With Tracealyzer, the application gets instrumented to record system actions. I can stream the data for example using SEGGER RTT. Or I can record data in a ring buffer.

In this article, I’m using VS Code with NXP LinkServer based debugging on the FRDM-MCXN947 board. It works fine with cortex-debug and mcuxpresso-debug extensions.

See the details in the post here.

Anthony Kouttron has a camera gear collection problem and as part of a personal 12 step plan, he restrict myself from purchasing functioning lenses.

This sounds illogical, and it frankly is, but it’s very hard for me to resist heavily discounted lenses. To keep my hat, I tend to only bid on lenses that are less than 1/4 of the going used sale prices and have little to no mechanical damage.

In this case I’ve been eyeing the recently produced sigma I-series lenses that feature mostly aluminum construction. A broken 45mm f/2.8 lens popped up on ebay in January for a song and a dance, and I simply could not resist.

Check out the disassembly and repair in the post here.

For more than two decades, OpenCV has been the foundation for computer vision research, robotics, embedded vision, AI applications, industrial inspection, AR/VR, medical imaging, and countless production systems. Today, the library has more than 86,000 GitHub stars, more than a million installs per day, and one of the largest collections of computer vision algorithms in the world.

The new OpenCV 5 builds on that foundation with a major modernization of the library. It brings a new DNN engine, stronger ONNX support, hardware acceleration improvements, better Python integration, new data types, expanded 3D vision capabilities, improved documentation, and a cleaner architecture for the future.

Modern applications now combine classical vision, deep learning, transformers, large vision models, edge deployment, heterogeneous hardware, and Python-first workflows. Developers expect the same code to run efficiently across laptops, servers, embedded devices, ARM chips, Snapdragon platforms, and specialized accelerators.

OpenCV 5 was designed to meet that reality.
