Reads for All Ages #Juneteenth2026

 

NYPL staff have once again put together a fantastic reading list, this time to honor Juneteenth:

The books below, both fiction and nonfiction and for a span of age groups, delve into the Juneteenth holiday directly or take place during the joyous, yet tumultuous time period as slavery officially ended and freed Black people faced new forms of economic, legal, and societal barriers rooted in racism.

The list provides reads for kids, teens and adults. Here’s a link to a recommended reading list exploring slavery and memory in the United States curated by Penguin Classics and The Lapidus Center at the Schomburg Center.

Bringing PebbleOS to Raspberry Pi RP2350 boards @Raspberry_Pi

Frederick Blais has taken PebbleOS, the smartwatch operating system, and made two ports for Raspberry Pi RP2350 boards:

1. Adafruit Fruit Jam RP2350 with a Waveshare/Pebble-compatible 144×168 Sharp Memory LCD, DS1307-compatible external RTC support, and ESP32-C6 HCI UART Bluetooth.
2. Raspberry Pi Pico 2 W with the shared RP2350 display, time, storage, resource, and USB CDC profile scaffolding. The normal Pico 2 W PebbleOS image still uses stub Bluetooth while the CYW43439/CYW43 backend is brought up separately.

PebbleOS is a lightweight, power-efficient operating system originally developed for Pebble smartwatches and now released open source. It supports custom watch faces and apps using C and JavaScript. Optimized for memory-in-pixel (MIP) displays and long battery life, it features Bluetooth sync, a timeline interface, and a strong developer ecosystem through an open SDK.

Nothing exemplifies the specialist better than the cucumber. “As cool as a cucumber” is the paragon specialist.

“Cucumber” (or as I learned that it sometimes was referred to as cowcumber) doesn’t even crack the top ten in usage for any other adjective. On the other hand, you have the noun “hell,” which is a top-10 noun for 17 different adjectives.w

This Jacket Pulls Drinking Water From Thin Air #Wearable

“The textile incorporated into the jacket collects moisture and funnels it to detachable harvesting units.” Image Via UT News

 

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.”

Reviving Teletext for Ham Radio #HamSunday @IEEESpectrum

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.

Raspberry Pi USB-C Gadget mode @Raspberry_Pi

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.

A library for turning sensor data into useful motion features

Puara Gestures is a lightweight C++ library for turning sensor data into useful motion features. It is designed for embedded systems and real-time projects that need gesture-style signals from accelerometers, IMUs, touch arrays, and buttons.

What this library gives you

• 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.

Why it is useful

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

Reverse engineering the TI-84 Plus OS

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.

Computer Lessons: A history of using computers in education

Over on the Creatures of Thought blog, is an excellent, detailed essay on how computers have been linked to education from the 1960s to the 1980s.

The belief that computers would revolutionize education took root long before the microcomputer era; it had spread rapidly across American universities in the 1960s. The political and technical moment were both ripe: the Soviet launch of Sputnik in 1957 and Lyndon Johnson’s Great Society programs both catalyzed massive new flows of federal money into education, and into educational research in particular.

Meanwhile, time-sharing, which allowed multiple users to simultaneously access a single large, expensive computer, made it conceivable to teach whole classrooms of students at once by computer (though this was still very expensive, given the price of computers at the time).

However confused the original purpose and function of classroom computers, they became by the mid-1980s an unquestioned necessity. That schools were obligated to expose their charges to the basics of the computer became an accepted fact-of-life of twentieth-century schooling.

This mirrored a broader trend of personal computing: in a handful of years it went from curiosity that large organizations ignored, to an experiment that a few early adopters within large organizations took up, to a requirement that large organizations controlled. Nothing better embodied this transformation than the IBM Personal Computer.

See this excellent piece here.

NEW LEARN GUIDE: Use Blinka in Ubuntu Core on Raspberry Pi #Sensors #AdafruitLearningSystem @Adafruit

Ubuntu Core is an OS intended for use on devices embedded within commercial products or industrial equipment. It’s very locked down by default. It runs on lots of different hardware, this new guide focuses on Raspberry Pi 3, 4, and 5 devices. It is a very different kind of OS than the traditional Raspberry Pi OS, which is aimed at students, hobbyists, and tinkerers. The locked down nature can make the development iteration cycle slower and more tedious than traditional Pi OS. Ubuntu Cores strengths really shine most after you’ve already got a project functioning how you want under a more traditional OS like Pi OS or Ubuntu Server/Desktop and you are ready to deploy somewhere remote.

The Ubuntu Core documentation describes the OS like this:

Ubuntu Core is an immutable and transaction-based version of Ubuntu that’s engineered for cloud, embedded, and IoT systems.

It provides an image-based deployment infrastructure with automatic updates for sandboxed applications, enabling the creation of production-ready systems with minimal attack surface and automatic rollback capabilities.

Ubuntu Core reduces the time to production by eliminating manual provisioning, ensuring systems remain secure throughout their lifecycle, and enabling rapid updates across fleets of devices at scale.

It is designed for embedded Linux developers, IoT device manufacturers, cloud-based applications, and organizations deploying embedded systems in robotics, automotive, signage, industrial automation, and IoT applications – from single devices to thousands in the field.

This new guide features pages covering installation, a sensor dashboard demo, and building custom snaps and images.
