PebbleOS isn't the only player in this space. There's also https://www.espruino.com/ which powers https://banglejs.com/. It's a tiny implementation of Javascript for microcontrollers, so it's really easy to hack your device in real time.
Had never heard of bangle js, love the idea of fiddling with it with a languange I already know.
Would love to buy the 1st version, as I don't like square designs, but it seems they don't sell it anymore.
I’m confused, is bangle js manufacturing new hardware (and is that open with schematics, bom, gerbers) or just shucking an existing cheap Chinese smart watch (SMA Q3)?
It also powers the Fallout Pip boy and possibly some other stuff from the wand company: https://www.thewandcompany.com/fallout-pip-boy/ See: https://github.com/orgs/espruino/discussions/7577
