I have a garmin from the late 90s and am saddened by the lack of FOSS software to even sync a new map onto it

not sure if this will help you but there is a neat website that allows you to build free maps for older Garmin models that didn't have them at first like Fenix5 https://garmin.bbbike.org/ 1990s is going way back though, they didn't even have mass-storage mode then, it was their proprietary "garmin mode" for usb which only things like BaseCamp can talk to

oh bud, mine doesn't even mention USB in the manual. I got the thing for like a dollar at goodwill haha

LILYGO site shows pre-orders of all 3 versions are sold out unfortunately.

There's an older "Plus" model available on Amazon.[1] Surprisingly cheap, at US$66. This new model is the "Ultra".

It's amazing that the market is big enough to get the price that low.

There are only a few features I care about in a smartwatch: 1. O2 monitoring. I have sleep apnea and live at high altitude, so this matters to me. 2. Motion sensor. Also mostly for tracking sleep. 3. Vibrator for notifications. 4. A screen backlight. 5. Battery life longer than a week. 6. Waterproof enough to survive a splash in the shower/rain. I consider GPS, cellular, AI, touchscreens, cloud-only sync and control…

The Sensor Watch circuit board [1] inside the case of a Casio F91-W / A158W / A159W satisfies 2, 4, 5, and 6. Accelerometer or thermometer available as daughterboard. Battery life measured in months, if not years. Although the simple LED backlight and the segmented LCD leaves a bit to be desired, and there is no wireless connectivity for notifications. Open source firmware. The Ollee watch circuit board [2] is simila…

my experience with a sensor watch has been terrible.

imagine breaking a $3 watch that is not quite as indestructible as people think it is, but it is nonetheless pretty robust, and then trying to shove something 100x glitchier and 5x as expensive into its case...

Different use case (environmental data recorder) but our current product uses an STM that turns on an ESP32 (not trusting that sleep mode) when it needs radio, to run on 2 AAs forever.

Do you have any info you can share on this recorder? Sounds really interesting!
