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.
