UPDATED PRODUCT – Pulse Sensor Amped

__________________________________________________________________________________________________

Pulse Sensor Amped is a greatly improved version of the original Pulse Sensor, a plug-and-play heart-rate sensor for Arduino and Arduino compatibles. It can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heart-rate data into their projects.

Pulse Sensor Amped adds amplification and noise cancellation circuitry to the hardware. It’s noticeably faster and easier to get reliable pulse readings. Pulse Sensor Amped works with either a 3V or 5V Arduino.

Lastly, the Pulse Sensor creators have also streamlined and improved the Processing visualization software and Arduino code that comes with this hardware.

The kit includes:

• A 24-inch Color-Coded Cable, with a standard male header connectors. Plug it straight into an Arduino or a Breadboard. No soldering is required.
• An Ear Clip, perfectly sized to the sensor. It can be hot-glued or epoxied to the back of the sensor to get reading from an ear lobe.
• TPU Stabilizer Ring + Velcro for a finger strap. This is another great way to get heart-rate data with more comfort and accuracy while maintaining some freedom of mobility.
• 4 Transparent Stickers, to insulate the front of the Pulse Sensor from oily fingers and sweaty earlobes.
• The Pulse Sensor has 3 holes around the outside edge which make it easy to sew it into almost anything.
• Visualization software (made in Processing) to instantly see output of the sensor and for troubleshooting.

NEW PRODUCT – Adafruit ADS7128 8-Channel ADC and GPIO Expander – STEMMA QT / Qwiic

__________________________________________________________________________________________________

The Adafruit ADS7128 8-Channel ADC and GPIO Expander is a bit of a Platypus of the I2C expander world: hard to categorize as just an ADC or a GPIO expander since it combines the capabilities of both with great capabilites! Usually, you only get ADC or I/O so it’s nice to see this combo product.

Featuring the aforementioned ADS7128, it can run on 3.3 or 5V logic and power, and all 8 I/O pins can individually configured to perform either 12-bit SAR analog input, push-pull or open drain digital output, or digital input. This makes it great as a general-purpose glue chip when you want to add more pins or analog/open-drain outputs to a microcontroller or microcomputer.

The ADS7128 also has a lot of fancy extras that make it a good ADC companion even if your main core already has analog inputs. It can run in standalone mode with zero-crossing detection or RMS computation. Not only can it count and track threshold crossings, but it also has an alert trigger output.

Developed by Studio Darius Ou with Benson Chong, Manual is a fully 3D-printed book that carries part of the machine code used to fabricate its own body.

The object arrives with a strange directness. Its pages, binding, and raised marks are produced in one printing sequence, so the book comes off the print bed already formed. There is no separate assembly stage, no later binding process, no applied graphic layer. The marks belong to the same material logic as the pages themselves.

The raised text printed across its pages is partial G-code, the instruction language used by the printer. In this sense, Manual carries a fragment of its own making within its body. It treats the page as both surface and construction record, giving the reader access to the object’s fabrication through touch as much as sight.

From the mail bag!

Heya Adafruit folks,

Just wanted to drop a note of “thanks” and “.. oh hot damn.” I’m a software
engineer and don’t usually find myself trying to wrangle the magic pixies
too often, but I had an idea for something very dumb awhile ago, bought a
bunch of random bits that I figured I could cobble together, and sure
enough, I could.

Ya’ll have done a great job at selecting quality odds and ends and have
shaved just enough of the sharp edges off of things that a lot of the tedium
is removed. But not so much trimming that you wind up hamstrung by “what if
we just pretended the filesystem didn’t exist” levels of simplification.

I don’t think I ran into a single bit of confusion with any of the products
you’d designed that couldn’t be resolved in 5seconds with a multi-meter. And
those were just bog standard boring things like “.. but which ground?” I did
find some bugs in a couple opensource gpio/ioctl packages that I spent a few
hours patching, but that’s both my wheelhouse and not in any way related to
your products/designs.

Anyhow, hope the summer finds you well. Was just reflecting on this big dumb
contraption I’ve made and thinking “I’d have never have done this if someone
hadn’t lowered the bar for of entry.” So thanks for that!

Cheers,

Garrett

Daniel Mangum bought a Pinecil soldering iron and wrote about soldering the breakout board and accessing the UART. This latest work is on JLink JTAG access.

I’ve been doing more work with the Pinecil as of late following the addition of upstream support for the Bouffalo Lab BL706 MCU in Zephyr.

While accessing the UART is helpful for viewing logs, debug access is critical when chasing down early system initialization and driver issues. While there are a variety of JTAG probes on the market, I typically reach for my JLink due to its broad compatibility and robust tooling. In order to connect a JLink to the Pinecil, the breakout board described in my previous posts is required. It includes a 10-pin header for JTAG breakout with a 3v3 reference pin, 4 GND pins, and the standard JTAG signals.

Check out the JTAG use in the post here.

It is a userspace Linux driver for the ASUS ZenVision lid OLED — the 3.5″, 256×64 monochrome screen embedded in the lid of the ASUS Zenbook 14X OLED Space Edition (UX5401ZAS).

ASUS only ships software for this screen on Windows (inside MyASUS). This project reverse-engineers the USB protocol and lets you drive the panel from Linux: show images, play animations, or display whatever you like.

Status: working on UX5401ZAS. Other ASUS lid-OLED models may use a similar protocol — reports and PRs welcome.

It’s written in Python and under an open MIT license. See it on GitHub.

Every Wednesday is Wearable Wednesday here at Adafruit! We’re bringing you the blinkiest, most fashionable, innovative, and useful wearables from around the web and in our own original projects featuring our wearable Arduino-compatible platform, FLORA. Be sure to post up your wearables projects in the forums or send us a link and you might be featured here on Wearable Wednesday!

Skylight decodes ADS-B from a cheap RTL-SDR radio and renders the planes physically flying over you onto a ceiling-pointed projector. A jet you’d hear overhead glides across your ceiling at the same moment – labeled with its airline, type, and where it’s headed. Pure-black background so the projector’s rectangle disappears and only the aircraft (and stars) are lit.

It also draws the real sky behind the planes – sun, moon, bright stars and constellations, and live satellites including the ISS – all at their true positions for your location and time. Tune everything from your phone.

• Real-time overhead aircraft from a local RTL-SDR (sub-second), or from a free web API with zero code changes – handy for trying it with no radio.
• Type-aware glyphs in a luminous, swept-wing style: widebodies tower over regional jets, helicopters spin their rotors, turboprops and GA aircraft spin their props.
• Smooth motion – interpolates the ~1 Hz fixes to 60 fps by rendering slightly in the past and tweening between real positions (no teleporting).
• Comet trails, altitude-graded color, and range rings + compass for orientation.
• The airport (runways) drawn at its true position, so you watch departures and arrivals line up with the runway.
• Window to elsewhere – each routed flight shows its destination city, local time there, and miles-to-go, plus a faint great-circle arc toward where it’s headed.
• Live sky layer – sun, moon (with phase), bright stars + constellation lines, naked-eye planets, and satellites / ISS computed from TLEs. Scrub time forward/back from your phone, or jump straight to the next ISS pass.
• Phone control panel – every setting (rotation, theme, palette, filters, sky toggles, …) is live-tunable over your LAN and persists across reboots.
• Optional sky camera – point a PTZ camera (VISCA-over-IP + RTSP) at the sky and Skylight automatically films the planes it’s projecting: ADS-B-driven pointing with latency-compensated lead prediction, a hybrid vision system that locks the plane to center, and a confidence-gated zoom ladder that punches in as the lock holds. Includes a TV dashboard (/tv.html) with the live feed + radar inset, and a full debug UI (/tracker.html) with jog pad, target table, and a star-capture calibration wizard.
• Appliance-ready – boots straight to a full-screen kiosk on a Raspberry Pi 5 (dual-output: projector + TV dashboard).

The project uses an 8GB Raspberry Pi 5 and a RTL-SDR radio receiver dongle. The display is a native 1920×1080 projector.

It’s all under an open MIT License and the author is looking to crowdfund kits.

pydafruit_gfx is a Python tool to quickly prototype Adafruit GFX displays in Python by hackster.io user mars91.

I find it frustrating when building a display (with Arduino + hardware), you have to: flash the board, a cable can go bad, a wire pops loose, or the board can decides to brick itself. I end up spending 10–20 seconds (if I’m lucky) just to see if moving a font three pixels to the left “feels right”.

I’ve always wanted a faster way to prototype display layouts and graphics, so I built this Python tool.

Instead of mimicking Adafruit’s GFX code, why not just use it.

Pydafruit GFX uses:

• Adafruit GFX graphics code
• SDL (a display window that works on macOS, Linux, and Windows)
• pybind11

Using Adafruit’s actual GFX code is great because there’s no uncertainty. Did the font copy correctly? Is that function actually implemented correctly? So instead – just use their code. Their code is the source of truth.

Check out the code on GitHub and more info on hackster.io.

Meta has unexpectedly breathed new life into its legacy Portal hardware by quietly unlocking ADB (Android Debug Bridge) developer access across the entire product lineup.

In a recent video update posted by Meta CTO Andrew “Boz” Bosworth on his Facebook Profile, he showcased a custom smart home hub he “vibe coded” using modern AI tools. He used the opportunity to announce that the very same developer tooling ecosystem utilized for Meta Quest headsets now officially supports Portal devices. This means users can finally repurpose their forgotten smart displays into powerful, customized Android devices.

Getting started with this modification is surprisingly straightforward and does not require complex hardware jailbreaks. Users simply need to navigate to the Portal’s Settings menu, find the Debug options, and toggle on USB Debugging or ADB access. From there, connecting the Portal to a computer via a high-quality USB-C cable (or removing the hidden rubber port plug on a Portal TV) unlocks full command-line capability. Once authorized through the standard Android SDK platform tools, users can instantly push apps using the adb install command.

This policy shift effectively transforms old hardware into a blank canvas for smart home enthusiasts and hobbyist developers. If you are looking to build your own dashboard or explore what is possible, you can check out the official walkthrough on the Meta Horizon OS Developer Blog or download starter blueprints directly from the Meta Quest Portal Samples GitHub Repository. Whether you want to sideload a Home Assistant panel or build a custom photo frame from scratch, these newly opened developer channels offer an excellent way to keep your Portal out of the landfill.

Rodrigo Copetti analyzes the PlayStation architecture:

Sony knew that 3D hardware could get very messy to develop for. Thus, their debuting console will keep its design simple and practical… Although this may come at a cost!

(The Playstation uses the) Sony CXD8530BQ, one of the two big chips this console houses. It’s what we would call a ‘System-on-Chip’ in today’s terms.

The resulting CPU core runs at 33.87 MHz. Like other MIPS R3000-based CPUs, the CW33000 supports configurations with up to four coprocessors. Sony customised it with three: System Control Coprocessor, Geometry Transformation Engine, and Motion Decoder.

See the full, well researched details on the website here and in book form here.

Kevin was messing around with the Raspberry Pi Pico RP2350 and PIO and at some point wanted to see if it could be hooked up to a Z80.

As a starter, I’ve been experimenting with seeing if I can get an RP2350 to see the Z80 address and data bus in any manner.

Of particular interest to me is the clock speed. In particular, what is the minimum clock speed possible?

I’m using the Arduino Pico core from Earl Philhower which makes it easy to build and download code to the RP2350, but I’m trying to stick to Pico C/C++ SDK functions rather than using the Arduino environment overlays.

Naturally this is a pretty crazy thing to be doing, but it is showing the basic idea.

If you ever used a computer in the ’70s, ’80s, and ’90s, your first foray into programming was most likely with BASIC. How-To Geek’s David Delony presents the reasons why Python has taken its place as the language of choice for people learning to program.

1. Python is everywhere
2. It’s easy to get started with
3. There’s a lot of info available

Python is BASIC’s spiritual successor

Python is easy to get started with and powerful enough even for complex tasks like scientific computing. It’s no surprise that it’s emerged as a language of choice.

See the details in the yahoo!tech article here.

The 46-year-old BASIC09 programming language has new compiler support with a front-end having been developed for the LLVM compiler stack.

BASIC09 was developed in 1980 for the Motorola 6809 CPU running with the OS-9 operating system. With this LLVM compiler front-end, you can write BASIC09 code for modern software and hardware.

Boisy Gene Pitre wrote in the RFC announcement of this BASIC09 front-end:

“BASIC09 was a structured BASIC dialect used on OS-9/6809 and OS-9/68K systems, especially the Tandy Color Computer ecosystem. It has procedures, typed variables, arrays, control flow, and a compilation model that makes it a reasonable candidate for preservation through a modern compiler infrastructure.

In the early days of home computing, the VICModem was Commodore’s answer to getting users online. But in Canada, things got… complicated.

To get around strict telecom regulations and technical limitations, Commodore did something unique: they bundled the modem with a rotary dial telephone made by Northern Telecom—specially branded and only ever sold in Canada.

The Northern Telecom Commodore Phone is one of the most obscure and region-specific bits of Commodore history. Only available in Canada, and only sold with the VICModem, it’s a rare find today—especially in working condition, with the VIC-1605 adapter still intact.

Andrei Cebotar is 37, lives in Moldova, and has Spinal Muscular Atrophy.

My hands get tired fast — by the end of the day I often can’t feel them at all. I can press one mouse button. That’s mostly what I have to work with. And yet I play games, I write, I have conversations online. This is how.

This isn’t a neutral roundup. These are the tools I use to access my computer and play games. Some of them are part of my daily routine, others I tried and eventually stopped using. What works for me may not work for everyone, but this is the setup I’ve built around my own needs.

• PlayAbility — my face is my controller
• Handy — I speak, it types
• Xbox Adaptive Controller — the foundation I build on
• Tobii Eye Tracker — useful, but I stopped using it
• Talon Voice — powerful, but not for me
• The combination is the point

None of these tools solves everything on its own. What actually works is layering them. Right now, on a typical day, I’m using PlayAbility for in-game actions, Handy for any text I need to write, and the Xbox Adaptive Controller for movement. Each covers what the others can’t.

AI coding tools are raising new issues with how that “clean room” rewrite process plays out legally, ethically, and practically.

Those issues came to the forefront last week with the release of a new version of chardet, a popular open source python library for automatically detecting character encoding. The repository was originally written by coder Mark Pilgrim in 2006 and released under an LGPL license that placed strict limits on how it could be reused and redistributed.

Dan Blanchard took over maintenance of the repository in 2012 but waded into some controversy with the release of version 7.0 of chardet last week. Blanchard described that overhaul as “a ground-up, MIT-licensed rewrite” of the entire library built with the help of Claude Code to be “much faster and more accurate” than what came before.

“Now the process of rewriting is so simple to do, and many people are disturbed by this,” Italian coder Salvatore “antirez” Sanfilippo wrote on his blog. “There is a more fundamental truth here: the nature of software changed; the reimplementations under different licenses are just an instance of how such nature was transformed forever. Instead of combating each manifestation of automatic programming, I believe it is better to build a new mental model and adapt.”

Found in the Obama White House Archives is a history of women pioneers in STEM, including some engineers, who changed the way our world is understood.

Today we are celebrating International Women in Engineering Day! German Professor and Author Anna Frebel, PhD, who is currently working at MIT, has shared some great advice for women are leaders or are looking to become leaders in STEM fields, via The Society of Women Engineers:

When you are encouraged to lean without a foundation, your instincts correctly sense the risk. You don’t lead; you wobble. Without strong roots, leaning too far puts you at risk of falling, or worse, failing. Before you can lead a lab, a clinic, or a technology organization, you have to make sure you understand the biggest roadblocks. That work begins with what I call leadership of self.

Here are the five shifts that help women in emerging STEM fields expand their goalposts and step forward with grounding rather than hesitation.

Software developers are soon going to have to take a lesson from Hemingway.

It’s not hard to be concise in code. You have to be, by design. Claude Code, Codex, Copilot, and the rest all love to be “spoken” to in Markdown.

We used to define our code with unit tests and specifications written for humans. Now, it’s all about the spec. And the spec needs to be both complete and concise.

It needs to be complete in the sense that if you leave something out or forget to define something, the agent will very likely fill in the gaps for you. Forget a feature or requirement, and the agent will go off confidently and almost certainly in the wrong direction.

At the same time, you need to be concise. Because if you are too effusive, you may give the agent ideas that you don’t want it to have. If you write like Fitzgerald — lush and expansive —  the agent will be off and running in a direction you can’t be sure about.

A New Raspberry Pi Desktop Style Refresh

What is currently known as the Raspberry Pi Desktop has been around for over a decade now – it started out as a customised version of the LXDE desktop, and over the years has slowly evolved into something with almost entirely different underpinnings, based on Wayland and labwc. Now comes real change – Raspberry Pi News. Via Adafruit Blog.

“We are now ready to roll changes out for beta testing. If you update your system from the beta repository, you ought to notice no differences at first, but the components which enable the new desktop will be installed and ready to use. The biggest change in the new desktop is the introduction of an icon dock, in addition to the existing taskbar. Two new plugins have been added which are intended to be used in the dock – one is a graphical application launcher, and the other an icon-based combined quick launcher and task list.”

What is the team up to this week? Let’s check in:

Dan

I continued fixing more issues for the CircuitPython 10.3.0 release. The fixes included more Espressif BLE fixes, some clarifications on PDMIn on Espressif, and fixing a regression in camera support when we upgraded to ESP-IDF 6.

Tim

The Raspberry Pi video feedback guide I mentioned last week is now wrapped up and published. Next I am looking into USB Audio protocols. The goal is to enable CircuitPython to act as USB Audio output/input devices like a microphone or speaker. I’ve started with the input/microphone side. The CircuitPython device gets seen as a USB microphone by the computer it is connected to and Python code can control what sound gets sent into the channel with synthio and other audio APIs. I started by adapting existing examples from TinyUSB and then porting the functionality into a CircuitPython module using the lessons learned. I will demonstrate the new functionality with a morse code paddle project.

This week I am starting to document the CircuitPython chiptune player project. I have written a CircuitPython helper library that emulates the AY8912 sound generator using synthio. It also decodes VGM (video game music) sound files. Noe is working on an enclosure and we will wrap everything up next week.

When maker Cameron Paczek moved into a new home directly beneath the take-off path of San Francisco International Airport (SFO), his visits to FlightRadar24 increased significantly. During SFO departure pushes, planes fly just 600–800 feet above his house every couple of minutes. The shaking of the house quickly became his cue to run outside and catch a glimpse of the aircraft before inevitably turning to the online flight tracker to see what he’d missed.

Video game consoles have a long history with web browsers. From the advent of the World Wide Web, consoles have been trying to get online. Browsers on video game consoles were initially very much an attempt to provide a cheap gateway to the web for a casual audience lacking technical expertise, though as time progressed they’ve become a greater and more integrated part of systems.

Declan Chidlow takes a look at browsers on video game consoles in detail, though only covers official web browsers. Many consoles have browsers installable via custom firmware and homebrew, but they’re beyond the scope of this post, as are non-web systems such as Satellaview and online services that didn’t provide a browser, such as XBAND, Sega Meganet, and Sega Channel.
