This week @adafruit we’re making multi-color lamps featuring stained glass effects and diffused panels with geometric shapes inspired by impossible objects. For the shop talk segment, we’re taking a look at the Make My Lithophane from MakerWorld to generate CMYK multi-color panels. This week’s time lapse features a mechanical fidget in the shape of a heart.

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.

Thanks to dcd for time codes!

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!"
