this is wild - claude code got PebbleOS booting in qemu in browser (wasm) overnight with no input from me. Took 6 hours in --dangerously-skip-permissions, but I woke up to success!

Just received the first batch of complete Core 2 Duos! We're still working on finishing drivers for all peripherals in PebbleOS. But it's wonderful to see it working, connected to my phone over Bluetooth, downloading watchfaces, etc!

- battery life is still unoptimized in PebbleOS, but we've verified that the hw can hit 30+ days

Last PebbleOS update for Pebble 2 Duo boosted battery life by almost a week. Median battery life is now 26 days! FYI this only counts devices that are connected by Bluetooth to Pebble mobile app, and have analytics enabled.
More improvements for PT2 in the works!

Does anyone want to port PebbleOS to ESP32-S3? I'll fund development and send you my brand new T-Deck Pro 😃
