Federal Theatre's 1939 marionette production of R.U.R. (Rossum's Universal Robots), the 1920 Czech play that invented the word 'robot.'

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

🎭🤖 from a 1920 Czech play about robot uprisings to... now.

Perfect for the Psycohistory box.

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 🎸

grid showing 45+ works tested against apple's on-device LLM, color-coded by result: green for memorized (>90%, public domain), orange for partial fragments, gray for fabricated, blue for refused. the model perfectly memorized FizzBuzz and the MIT License but refused the Pledge of Allegiance and Churchill's speeches. it fabricated Moby-Dick, 1984, and both Gatsby passages. Bohemian Rhapsody, Imagine, Hotel California, and the Sorting Hat all blocked. the model knows Hello World better than it knows the world.

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.

Gustave Doré's 1863 engraving of Don Quixote in his study, gaunt and hollow-eyed in his chair, surrounded by a hallucinatory swarm of knights, dragons, demons, and damsels erupting from the books scattered at his feet. The caption reads "A world of disorderly notions, picked out of his books, crowded into his imagination." Engraved by H. Pisan. 162 years later, the scene describes every LLM training pipeline perfectly... consume everything, hallucinate it back as original work, and look slightly unhinged while doing it. The man who read so much he lost the boundary between absorbed and authored. Cervantes wrote the diagnosis. Borges wrote the legal brief. We ran 332 probes and got the lab results.

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!

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.

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!

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.

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...

Screenshot of the Arduino Open Source Report 2025 cover page with the hidden "STRICTLY CONFIDENTIAL" text selected, revealing it in a dashed selection box above the title. The text is in gray RobotoMono sitting right on the cover photo where nobody would notice it unless they did exactly what we did. Behind it, an Arduino board, a tennis ball, and a robot... none of which are OSHWA certified. Qualcomm's open source report: so open it's confidential, so confidential it's invisible, so invisible we found it anyway.

Chart showing year-over-year decline across every metric in the 2025 Arduino Open Source Report after the Qualcomm acquisition. Cloud CLI releases down 55%, Arduino CLI down 44%, new official libraries down 42%, IDE releases down 40%, upstream project contributions down 40%, Zephyr patches down 35%, MicroPython Lab down 33%, and community library versions down 3%. Everything is red. The only thing that didn't crater was the community, which kept shipping while Qualcomm was busy rewriting the Terms of Service. "Open source is love" says the report. The chart says otherwise.

STRICTLY CONFIDENTIAL: The 2025 Arduino Open Source Report

Qualcomm's first full year owning Arduino and every metric went down, but at least they remembered to leave "STRICTLY CONFIDENTIAL" in the PDF... 🔍📉
