NEW PRODUCT – NeoPixel Stick – 8 x 5050 WWA White LEDs with Integrated Drivers

__________________________________________________________________________________________________

What is better than smart LEDs? Smart WWA LEDs! These NeoPixel sticks now have 3 white LEDs in them in three tints (also known as ‘color temperatures’): warm white, cool white and amber, great for excellent lighting effects that want pure white lite. These are fun and glowy, and you can control each LED individually! Make your own little LED arrangement with this stick of NeoPixel LEDs.

This is the WWA version. We also have this stick in Natural White RGBW, Cool White RGBW, and good ole RGB!

The NeoPixel is mainly white LED with a yellow phosphor. Unlit, each section resembles an egg yolk. Lit up these are insanely bright (like ow my eye hurts) and can be controlled with 8-bit PWM per channel (8 x 4 channels = 32-bit color overall). Great for adding lots of bright white or warm tone dots to your project!

We crammed 8 of the tiny 5050 (5mm x 5mm) smart WWA LEDs onto a PCB with mounting holes and a chainable design. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~12mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC (4-6V works) and you’re ready to rock.

NeoPixel LEDs use 800 KHz protocol so specific timing is required. On NeoPixels, the PWM rate is ~400 Hz, which works well but is noticable if the LED is moving. In comparison, DotStars have a 20 KHz PWM rate, so even when moving the LED around, you won’t see the pixelation, the blending is very smooth. (we recommend DotStars if you can use them)

The LEDs are ‘chainable’ by connecting the output of one stick into the input of another. There is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microcontroller such as an AVR, Arduino, PIC, mbed, etc.

We have a tutorial showing wiring, power usage calculations, example code for usage, etc. for NeoPixel Please check it out! You can use any NeoPixel library with RGB support – instead of RGB you get WWA output so like what would be Red is instead Cool White.

Comes as a single stick with 8 individually addressable WWA LEDs assembled and tested.

Our detailed NeoPixel Uberguide has everything you need to use NeoPixels in any shape and size. Including ready-to-go library & example code for the Arduino UNO/Duemilanove/Diecimila, Flora/Micro/Leonardo, Trinket/Gemma, Arduino Due & Arduino Mega/ADK (all versions)

The Filament DryBox is a lightweight cover that fits a standard 1kg filament spool (20x20x8 cm) with an opening at the base. Simply place your filament roll on your heated print bed at 50-60°C, cover it with the Filament DryBox, and let the heat do the rest! Ventilation holes at the top allow moisture to evaporate efficiently. For best results, rotate the spool halfway through the drying cycle to ensure even drying on both sides.

pico-usb-wifi by 白一百 is firmware for the Raspberry Pi Pico W that turns it into a driverless USB WiFi adapter, enumerating as a USB CDC-NCM device.

A team of researchers led by The University of Texas in Austin have developed a soft wearable device called “NEUSLeeP” capable of stimulating deep brain regions and monitoring brain activity in real time. The study, published in Nature Communications, helped boost participants REM sleep.

“This is the first time we’ve been able to noninvasively target deep brain regions involved in REM sleep, while simultaneously monitoring brain activity,” said Kai Wing “Kevin” Tang, a recent UT biomedical engineering Ph.D. graduate who led the research effort. “Our skin-attached NEUSLeeP patch opens up new possibilities for understanding sleep and treating sleep disorders in home settings,” added Huiliang “Evan” Wang, assistant professor in the Cockrell School of Engineering’s Department of Biomedical Engineering, who supervised Tang’s work and served as the principal investigator (PI) directing the overall project.

I’m a bit of a calculator nerd. For a while, calculators lagged behind general-purpose computing because of the lack of a suitable display technology.

I constructed the display itself out of six generic “SO-45” panel voltmeters from Amazon, plus one vintage edgewise voltmeter scored on eBay.

The panel was the easy part; next, I had to come up with an enclosure.

The final portion of the project is the control circuitry. Some folks egged me on to implement analog calculations, but that would make the calculator even less practical — and if you want to take that route, purely-mechanical designs are more fun. So, the brains of the operation is an 8-bit AVR128DA28 MCU.

Are we approaching a reading crisis or does “THE END OF READING IS HERE” just make for a catchy headline?  Sounds like a lot of hand-wringing to me, but reading is fun! I hit a rut in my reading  and was amazed at how much an e-reader helped me dive back into content over 280 characters.

Elia Scotto has some more tips on how to put down the phones and read more. These are practical ideas (like carry reading material with you) that focus on habit building without becoming a chore. You don’t have to be aiming for a book a week to adopt a few of these tips.

I’ve read roughly a book a week for a few years, and I can tell you it’s doable. I didn’t always read this much. When I started, I read fewer than ten volumes per year, but making it a goal made me switch gears and achieve what I once thought was impossible. I want to explain to you here what I did to become a prolific reader, and what I learned in the process, so that, with a bit of effort, you can do it too. I promise, it will be worth it.

CircuitPython on the Xteink X4 eReader

Niche corners of social media are buzzing with reading content and book-lists. One device that gets a lot of attention is the Xteink X4. Many folks in our maker community find an intriguing device with a familiar microcontroller inside and think, “Will it run DOOM?”. Here at Adafruit, of course, that thought crosses our minds, but the more pertinent question is always “Can it run CircuitPython?”

See the full guide!

Bartosz Ciechanowski discusses the invention of the internal combustion engine in the 19th century and how it has revolutionized transportation over land, water, and air. All with detailed 3D images, many moving.

Despite their omnipresence in modern day, the operation of an engine may be cryptic. Over the course of this article I’d like to explain the functionality of all the basic engine parts shown (above).

Each part is built out until the whole is fully sketched.

Unchallenged for decades, the internal combustion engines in cars are slowly being supplanted by their electric equivalents, which are simpler, quieter, and more environmentally friendly.

Despite their drawbacks, classic engines still have something mythical about them – their intricate mechanisms are synchronized together to create carefully controlled conditions for harnessing fire in a truly Promethean way.

Tris Sherliker was made aware of an interesting shirt by CDN Akamai supplied via Uniqlo stores in support of their Peace for All campaign.

Is that … a shebang?! My wife was right that I’d want to see it. Was that… a shebang?

Take a closer look at the text block (above, partial)

Yes, a shebang! On a t-shirt sold in a high street store, no less. And it is clearly a base64 encoded Here string being fed to eval via base64 --decode.

After Base64 decoding, the resulting script is a welcoming and nicely commented Easter egg.

I won’t spoil it for you’, it’s a fun romp to the end and you can read it here.

Tadas Vilkeliskis posts about making their first printed circuit board:

About a couple months ago I purchased an Arduino Nano ESP32 dev board…Next was getting some peripherals so I ordered a small LCD and BME280 temperature/humidity sensor breakout boards. Both of these I was able to wire up to the ESP32 chip and get them to talk over the I2C protocol.

I decided to create the BME280 sensor module. This would let me get a feel for what it takes to design something starting with schematics and ending up with a custom PCB.

This experience gave me confidence that I can produce custom and working PCBs. This, of course, was a very simple project, but it took me through the whole process end-to-end. It gave me a better understanding of the steps I may need to take for more complex designs.

See the whole process in the post here.

Ever wonder if that empty corner of your yard is actually fit for sun-loving tomatoes or better off with shade-tolerant hostas? Instead of playing the gardening guessing game, this Learn guide walks you through building a battery-powered data logger designed to track the amount of sun a certain part of your garden gets on an average day. Built around the Adafruit ESP32-S2 Feather, the build uses a VEML7700 Lux sensor connected via plug-and-play STEMMA QT cables. By utilizing CircuitPython’s deep sleep capabilities, the microcontroller wakes up just long enough to capture ambient light levels and transmit them over Wi-Fi to a continuous Adafruit IO dashboard before instantly shutting down. This extends a standard LiPo battery pack’s lifespan from mere hours to several weeks of uninterrupted data collection.

The real magic happens once the data is gathered. Beyond charting beautiful, real-time light graphs on Adafruit IO, the guide details how to export your historical sunlight levels into a simple CSV format. From there, you can feed your raw lux data alongside your local USDA Hardiness Zone into an AI model to serve as a custom “virtual master gardener.” The AI analyzes peak sun hours and light intensity to deliver a precise, tailored list of perennials or vegetables guaranteed to thrive in that exact patch of dirt.

blinry wanted a clock in the kitchen without relying on the small one on the oven.

So I recently built a wall clock from a circular LCD screen! It’s really great because it can display any clock face you want, even ones you code yourself!

• Waveshare’s 7 inch circular LCD
• Raspberry Pi 3-5
• A microSD card as your storage, at least 16 GB
• Good USB-C power supply

I built a couple of clock faces myself. You can find an overview at clocks.blinry.org.

Very nice work, you can see in the article here.

The WHOOP 4.0 is a screenless fitness wearable designed for 24/7 continuous tracking. It focuses heavily on sleep quality, physiological recovery, and daily exertion levels rather than step counts. The tracker operates via a subscription model and is typically priced between $30/month and an annual fee of $239

Abdul Sahil isn’t knocking WHOOP. But the price stings.

When a membership lapses, the hardware is basically useless, You Own it, You still can’t use it, it just goes dark, because the app stops talking to it. So you’ve got a perfectly good sensor turning into a paperweight. That’s the only thing I set out to fix.

I spent a few weeks reverse-engineering how the 4.0 talks over Bluetooth, how it streams data, how to acknowledge its events so it keeps sending, how to capture and parse all of it. and built a small open-source stack around it. I tested the decoded values in different situations (wearing it, off-wrist, charging, workouts) and checked them next to my Apple Watch Ultra 1 to make sure they line up. I’m fairly confident in them, though I’ll say plainly I’m not claiming 100% certainty on everything.

The software is under an open MIT license and you can check it out on GitHub.

Pete Warden is convinced local voice interfaces and sub-$1 embedded chips will fundamentally change how we interact with everything in the physical world.

I’m so excited to introduce Moonshine Micro, a version of the Moonshine Voice open source framework that can run a useful voice interface in just 520KB of RAM. It contains separate libraries for voice-activity detection, speech to text, and text to speech, all powered by tiny neural networks with an example bringing them all together on an 80 cent Raspberry Pi RP2350 chip.

This release runs a 50-word command recognizer, that’s fully trainable for custom words, and a neural network-based text to speech engine, and can be used to set up a wifi connection.

Matthias Plappert at dfdx labs will spend the next several months doing independent research on robotic manipulation, and doing it in the open.

I don’t expect the main output to be papers or an open-source codebase. What I care about here is the research log itself: what works, what fails, and what I learn from running the system.

This note covers step one: building the full foundation for doing research. The first half is about the physical setup: an industrial-grade robot arm, two cameras, and teleoperation in a package small enough to live next to my desk. The second half is about the software stack I wrote from scratch to operate it. The video (below) shows the result in action.

A robot stack written in Python, running on a consumer laptop, is clearly only ever going to be a soft real-time system.

decrazyo on GitHub outlines the process for modding the Nintendo Entertainment System (NES) to use 2 PPUs for advanced graphical features.

I don’t expect anyone to actually bother building this so the docs might be kind of half-assed at times. Check out my modified fork of Mesen2 if you’d like to play with this concept without modding your NES. See the related projects section for some demos that take advantage of the dual-PPU setup.

• More colors
• More sprites
• Parallax scrolling

Eric Schlaepfer On Tube Time has designed the Beavis Ultrasound PnP, an open source replica of the Gravis Ultrasound Pnp.

Unlike other clones, this design includes the entire schematic as well as the reverse-engineered source code of the GAL.

While Eric notes “I have not generated the fab package since I have not actually fabricated the board and tested it for functionality. Build this board at your own risk.”, having a modern sound card replica for a classic IBM PC/AT and clone machine would be fantastic.

Frank Force (KilledByAPixel on GitHub) has created a 3D pen-plotter simulator in the browser.

Drop in an SVG and watch a little AxiDraw-style machine draw it on virtual paper.

The arm sliding, pen lifting, stepper motors whirring. It doesn’t make anything real but it’s nice to watch.

Speed — 1× (real time) up to 1000× for the impatient

Drag any SVG file onto the page and it loads onto the plotter.

azya on X (formerly Twitter) recorded a video of the IC decapsulation process.

The hot air gun nozzle is visible in the top-left corner, with the temperature set to ~150°C. This method works great for small chips. On larger dies, some compound often remains in the center, which I remove by boiling in rosin.

Maxime Rivest has created a project similar to the Harry Potter diary of Tom Riddle, using the reMarkable Paper Pro tablet.

Write on the page with your pen. After a pause, the diary drinks your ink — your words fade into the paper — the page thinks for a moment, and an answer writes itself back in a flowing hand, stroke by stroke, then fades away.

No screen glow, no keyboard, no chat UI. Just ink appearing on paper.

The diary’s replies come from a vision LLM that reads your handwriting from the committed page (sent as an inline PNG).

Although Harlem is well-known as a cultural hub for Black artists of various mediums, it also has a history of being overlooked and underserved in comparison to other pockets of Manhattan, leading to grassroots organizations and community-based programs to fill the gaps the city often didn’t provide. The Children’s Art Carnival in Harlem is one of them. Hyperallergic shares the importance of the Children’s Art Carnival in Harlem and it’s history of motivating children to nurture their creativity.

In March 1969, at the first-ever Children’s Art Carnival in Harlem, artist, activist, and educator Betty Blayton-Taylor looked on as groups of children painted at easels and strung objects together to make hanging sculptures. Held in a garage provided by the Harlem School of the Arts, the event engaged artists to conduct workshops for local kids. “Children can just as well use their energy to be creative as destructive,” Blayton-Taylor told the New York Times in a 1969 interview. “They’re having fun and that’s what we want.”
