New product coming soon! Adafruit PMW3901 Optical Flow Sensor breakout... tracks surface movement like an optical mouse, but built for drones and robots. SPI interface, onboard voltage regulation and level shifting for 3-5V. What will you build? 👁️ adafruit.com/new
Close-up photo of an Adafruit PMW3901 Optical Flow Sensor breakout board on a colorful workbench surface. The green PCB features the PMW3901 sensor with integrated lens in the center, a second IC labeled U2, passive components, and a row of eight labeled pins along the bottom edge: VIN, GND, SCLK, MISO, MOSI, CS, INT, RST. The Adafruit flower logo and "PMW3901 Optical Motion" text are silkscreened in white across the top.

"Any User Who Has a 3D Printer Would Have This Software Installed" ... says the CEO of a company in Spain @printandgotech that wants their DRM, file-blocking, print-policing software on every 3D printer in America.
PRINT&GO's Facebook page, operating out of a Spanish industrial park with one whole review to their name, announcing that the Manhattan District Attorney wants their file-blocking software installed in every 3D printer in America. Their photo gallery includes a graphic reading "One Software To Rule Them All," which is either a Tolkien reference or the most honest product positioning in regulatory capture history.

The RV-8803 is a ±1.5ppm temperature-compensated crystal real-time clock

We got a customer request for more precision real-time clocks in the store. We already stock the DS3231, which is a very popular precision RTC that has a temperature-compensated internal crystal.
We got a customer request for more precision real-time clocks in the store. We already stock the DS3231, which is a very popular precision RTC that has a temperature-compensated internal crystal. But the DS3231 is really chunky, and also there are new chips available! So this customer asked, could we please make a breakout for the RV-8803. The RV is more affordable than the DS and has ±3ppm stability over the temperature range and an amazing ±1.5ppm typical at room temp. It can also run from 1.5 up to 5 volts, so no level shifting or regulator required. No problem, we found the part on Digi-Key and spun up this little breakout that is nice and compact and has Stemma QT connectors on both sides and a CR1220 coin cell battery holder on the back! Coming soon to the Adafruit shop.

Desk of Ladyada – OpenClaw, eInk Hacking & Vibe-Coding an Oscilloscope 🦀🔬
youtu.be/zV4uNFiw_3E
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 (https://github.com/crosspoint-reader/crosspoint-reader) 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 (https://learn.adafruit.com/hacking-the-yoto-music-players). 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 (https://blog.adafruit.com/2020/10/13/stemma-friend-is-your-i2c-pal-i2c-scanner-demo/) 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.

With @adafruit.com raising the alarm about bills in NY and WA that would require 3D printers to refuse to print gun parts, here is a quick post on the technical problems with this approach (regardless of your thoughts about gun control)

New York Wants to Ctrl+Alt+Delete Your 3D Printer

In yesterday's episode of The Bootloader I said if one state like Washington is planning to do something like this, others will be, too. And a day later here's news of New York wanting something similar to 3D printers. Call your reps!

Looks like I get to spend some time (again) explaining why, no matter how well intentioned, the idea of mandating gun part scanners into 3D printers just doesn't make sense
