Hacking with Claude on a $27 Smart Watch

I launched Claude on my pebble watch face software some time ago. It was also great fun to see it rejuvenate a 10-year old obsolete code base and make it work very well on the latest pebble Time 2 watches now available (finally!) today.

Interesting, is Claude becoming the Kleenex of the agent world?

I really do wish the pinetime had more RAM; it's really really small and a pretty painful bottleneck.

Edit: Oh, once the "pro" version is out I guess there's an easy answer to that: https://pine64.org/2026/03/28/pinetime_march_2026/

Take the fun up a level with the Waveshare ESP32-S3 AMOLED 2.09” watch.

Power management is absolutely required, but it’s a fun platform. And for about the same price good display, peripherals and CPU.

I’d like to see one with the C6 variant for the low power core.

Yay, I wanted to do the same - glad someone did work on it and shared it! Thanks! Although I think what I've learned is that I actually don't like wrist bands, so... yeah.

The PineTime watch unfortunately does not have any microphone, so there is no possibility of voice control.

Not the point of the article but it did show a Bluesky post... I didn't know you could make the Apple Watch interface look different with a third-party app. I gotta try this out.

... This seems needlessly confusing/misleading? Author continues to use "Claude" throughout the article.

If it is open source, is it still considered hacking?

if you used the word "Hacking" anywhere in your project i'm suprised Fable didn't downgrade you.
