SHOW and TELL 2/18/2026

The u-blox SAM-M8Q has been sitting on my bench for months. This little GPS module has a built-in antenna, coin cell backup, speaks both NMEA and UBX binary protocol over UART or I2C. So why isn't it in the shop already? Well, it's mostly cause of the 475-page interfacing datasheet documenting every command, struct, and config register. Hundreds of message types. I got partway through by hand with some Claude Code Sonnet assistance, but ran out of time - plus it was still tedious when babysitting Sonnet. However, now we're living in an Opus + Codex era! So I pointed my Raspberry Pi OpenClaw at it. https://github.com/adafruit/openclaw Here's the setup: Raspberry Pi 5 running OpenClaw, wired to a QT Py RP2040, which talks to the SAM-M8Q. Opus 4.6 reads the datasheet (converted to markdown first by Sonnet 4.6 with 1M context to minimize re-parsing that PDF every session) and builds the implementation plan. I review the plan to make sure it prioritizes the most common commands and reports, and flagged some unessential sections like automotive-assist or RTK-specific. Then Codex is assigned each message implementation task as a sub-agent and writes the actual C code for the Arduino library. Opus suggested using struct-based parsing rather than digging through each uint8_t array; we just memcpy the checksummed message raw bytes onto the matching struct and extract the typed bit fields. We've got four message types done so far. After each message is implemented, Codex also writes a test sketch that will exercise / pretty-print the results of each message, great for self-testing as well as regression testing later. Tonight I'm telling it to keep going while I sleep: code, parse, test against live satellite data, fix failures, commit and push on success, then move on to the next. To me this is a great usage of "agentic" firmware development: there's no creativity in transcribing 84 different structs from a 475-page datasheet. Once the LLMs are done, I can review the PRs as if it were an everyday contributor and even make revision suggestions.

This week @adafruit released the stained glass lamp using the CircuitPlayground Bluefruit. Looking at some prototyping and work in progress. This week's time lapse features a mechanical fidget with helical gears.

Step right up and behold Professor Bubbleton's Breathing Head, a curious apparatus to keep your audience on the edge of their seats. A submerged head rests under theatrical LED illumination sealed inside a clear apothecary jar — until a visitor dares to tap the vessel, at which point the head responds with a sudden stream of bubbles, as though its humours have not fully departed upon beheading. At the heart of this modern marvel is the Circuit Playground Express, whose onboard accelerometer and NeoPixel light ring make it perfectly suited for sideshow duty. A knock on the jar is detected directly by the board, triggering a timed burst from a hidden air pump while the built-in NeoPixels provide customizable lighting effects. The result is a self-contained illusion that feels uncanny and responsive, without requiring complex wiring or extra sensors. Full tutorial: https://learn.adafruit.com/professor-bubbleton-s-breathing-head-in-a-jar/overview In this guide, you'll assemble the apparatus using readily available parts, mount the Circuit Playground Express inside the jar, and configure our simple code to coordinate the tap detection, bubble effect, and lighting. Along the way, you'll learn how to turn a single gesture into a memorable interaction — the kind that invites onlookers to step closer, tap lightly, and immediately question whether they should have done so at all. No actual beheading is required for this guide. Our effigy was not harmed in any way. We'll show you how to create this illusion with any head you'd like to submerge -- all you need is a few clear photographs. Or, use our example effigy for instant gratification!

This is a spectrometer on a chip, and it's getting the Adafruit breakout treatment. The AS7343 is the successor to our AS7341, bumped from 10 channels to 14, with 12 spanning visible light into near-infrared (380nm to 1000nm), plus clear and flicker detection. Same footprint and pinout as the '41, so your existing wiring and enclosures carry over unchanged. Ladyada finished the library and testing, then pointed OpenClaw at an ESP32-S2 TFT hooked up to the sensor. Claude generated a real-time color bar visualization that's one of the nicer sensor demos we've done… hold it over a green light and watch the yellow-green channels spike, wave it past a reddish-orange source and the spectral output shifts to match. If you want to see what multi-spectral color sensing can do, check out the Color Sensing Music Player guide – we use DUPLO bricks that play songs based on color. The AS7343 would make it even better!

This week at the Desk of Ladyada, we're back to hardware... with a baby in a bouncer and an LLM on the clock. The VCNL4010 proximity sensor has been discontinued, so we need to move to the VCNL4030. That means a new EagleCAD library file, and we're testing whether Claude Code (Opus, high effort) can generate one straight from the datasheet. Historically we've had to create a footprint for each device we use - and one of our gripes is how annoying it is to convert when manufacturers spec edge-to-edge pad dimensions instead of center-to-center pitch, which is what every CAD tool actually uses. In our experiment, Claude Code handled the math, got the pad sizes (0.65 x 0.75mm) and pitch (1.05mm) correct on the footprint, arranged logical pin grouping on the schematic and matched pin-to-pad correctly.. It even matched our drawing style by learning from existing Adafruit library files in the repo. The whole run took about 4 minutes and 45 seconds.Nota bene: it's not perfect! Our first pass had schem label overlaps and an unnecessary exposed center pad (Gemini Deep Think was actually smarter about skipping that pad). We also tried having Claude Code design a full QT Py terminal BFF board... it worked-ish but needed enough back-and-forth that doing it by hand would've been faster. Footprint generation is ready for integration into our workflow - maybe we'll kick it off while we review the datasheet - but, full board layout isn't quite there yet. Other things on the desk: we're setting up OpenClaw to subscribe to every chip manufacturer newsletter and generate daily reports on new components worth stocking. New protos include the TMF8806 time-of-flight sensor from AMS (up to 10 meters, and possibly simpler drivers than ST's VL53 series) and a PMW3901 optical flow sensor often used in drone navigation.

This week at the Desk of Ladyada, we're comin' back from maternity leave and getting spun up with a bunch of projects. First, a fun mailbag item: the XTEInk ‘pocket' reader running crosspoint open firmware on an ESP32-C3. Since it's running an Espressif chip, we could also install CircuitPython or WipperSnapper on it…a great side-effect of more off-the-shelf goods coming with ESP32 chips! See also our Yoto-hacking guide on learn. Next, we've been really enjoying running OpenClaw on a Pi 5 and connecting it up to Adafruit hardware to do ‘full circle' test-driven development. We have Anthropic Opus do the datasheet parsing and design document, then ‘farm' out the coding work to OpenAI Codex. After the driver is written, we also have it design tests to verify hardware functionality, using other GPIO pins, NeoPixels, servos, etc., to exercise the chip capability. It's able to run tests and then fix bugs all on its own, then text me when it needs help or to alert that it's done. It's very slick and fun! Finally, using that same system of coding, we had it ‘one-shot' a miniature oscilloscope demo for the unreleased Stemma Friend from way back (well, it took a few back-and-forths to get it just how we like). Could we have coded it by hand? Probably! But we were able to guide the development and get the look and performance we wanted in about 30 minutes of prompting while also laying in bed and chillin' with a newborn.

Join Scott as he recaps his LLM agentful week and how it's changing how he works. He'll also try to answer any questions folks have.

Ladyada: "I've only had OpenClaw installed on this Raspberry Pi 5 for a couple of days, but boy, have we burned through a lot of tokens and learned a lot. Including what I think is a really fun improvement in my development process: “Agentic test-driven firmware development.” I've used LLMs for writing code as a sort of pair-programming setup, where I dictate exactly what I want done. But this is the first time that I'm giving full access to the hardware to the LLMs and letting Claude Opus 4.5 as a manager to control Codex subagents. Not only does it parse the datasheet for the register map and functionality, Claude also comes up with a full development and test plan, writes the library, tests it on existing hardware, and then also works up a test suite that covers all of the hardware registers to make sure that the library is exercising the entire chip capability. For example, here I give it an APDS-9999 color sensor and a Neopixel ring and tell it, “hey use the Neopixel ring to verify that we're really reading red, green, and blue data properly from the sensor,” and it will do the whole thing completely autonomously… no humans involved! I still review the final code and ensure the tests genuinely validate the functionality, not just take shortcuts. There is a phenomenon known as "reward hacking" (also called "specification gaming"). The model may optimize for passing tests as a metric, rather than ensuring the code truly works as intended. So far, the results have been excellent... no surprise, since these LLMs are trained on Adafruit open-source GitHub repositories!"
