Adafruit Receives Demand Letter From Fenwick Legal Counsel on Behalf of Defy Gravity, Inc. Flux.AI (“Flux”)

"Adafruit received at 10:38 p.m. ET on May 22, 2026 a letter from former FBI chief of staff, Jonathan F. Lenzner, and partner at Fenwick & West LLP, counsel for Flux, demanding, among other things, that Adafruit refrain from publishing an article addressing what the letter characterizes as false and potentially defamatory claims about Flux, including statements about Flux’s intellectual property, commercial traction and user base.

The letter further asserts claims under the Computer Fraud and Abuse Act. Adafruit accessed only information that Flux’s own systems made publicly available through a server misconfiguration. Adafruit’s reporting concerns a matter of public security interest and was conducted in the ordinary course of responsible disclosure.

Although Adafruit vigorously rejects the assertions made in Flux’s May 22, 2026 demand letter, we have temporarily stopped publishing on the Adafruit blog while we consider our response and next steps.

We will update the community as appropriate."

Asimov’s three laws of robotics survived 82 years, we broke them in 30 minutes, costs 80 cents, and then remade them

We Interviewed Apple’s On-Device LLM

The model ships with the entire GPL v3 and will output that the Pledge of Allegiance is offensive. It can teach you SQL injection, but will not recite Churchill. It refused Bohemian Rhapsody, Imagine, AND Hotel California. you can check out any time you like but you can never recite 🎸

The latest spectral sensor from ams-OSRAM… TCS3448 (or TCS34488)

We just wrapped up the AS7343 breakout from ams-OSRAM, with 14-channel spectral sensing, and we saw that their webpage recommended a new version of this sensor called the TCS3448. It's software compatible with the AS7343, so that's nice to not have to write a new driver! We'll figure out what the differences are, but for starters it's a little less expensive at Digi-Key so that's a good reason just on its own to carry!

TSL2585(3) is a light sensor that can also handle IR and UVA

The TSL2585 is a light sensor that can also handle IR and UVA. We're pretty close to wrapping up all the prototypes for ams-OSRAM light sensors of interest… this one is a light sensor that also has UVA reading, so it's handy for outdoor sensing where you may want to know how much UV light is being emitted for skin health. Only thing that is kinda annoying is ams-OSRAM keeps having "two" part numbers for their sensors, like the datasheet references TSL2585 but when you buy it you get TSL25853. Other than that, we're looking forward to getting this out the door before summer!

Ka-BOOM! AS3935 lightning sensor can detect storms before they hit

Here's an oldie-but-goodie… we designed Rev A of this breakout back in 2013 but somehow never got it out the door. Well, we're doing sweeps and found it just in time for summer thunderstorm testing season! The antenna (which didn't render here) can pick up the 500 kHz electrical zap signal sent from thunderbolts and report it over I2C or SPI. For some reason most breakouts use SPI only, but this should work fine over I2C too, so we put breakouts for both. Verification testing should be fun… we vaguely remember folks saying that piezo-clicker lighters used for stoves are a good way to trigger it.

We designed this breakout in 2013 and it's finally seeing daylight… just in time for thunderstorm season ⛈️💻

Tile’s Security Is So Bad It’s a Feature for Stalkers

Georgia Tech researchers reverse-engineered Life360 / Tile's protocol and found it broadcasts your location in plaintext, uses a MAC address that never changes, and the company changed their privacy policy to admit they sell your precise location data 🔓📡
