have wished for decades now there was an open-source Garmin on the level of Cyanogenmod / LineageOS for Android
not sure if it will happen this decade but definitely next decade
proper running/cycling metrics are hard as demonstrated by how many well-funded competitors are somewhat close but not there 100% yet (Coros, Amazfit, etc)
someone once hacked and decompiled older Garmins but newer ones are encrypted/signed/locked-down
The peripherals are great until you realize there's a dirth of software to use with them .. like, GPS is fun and everything, but not if all you've got is the coordinates ..
I really love the idea of LoRA in a watch though, so I hope that once this gets shipped, the software makes some leaps and bounds ..
This device looks capable of a lot of features and possibilities. Unfortunately nothing comes to my mind because I'm not good with diy hardware (once connected raspberry pi zero with led strips). Could someone tell examples of interesting and/or useful projects one can implement with this watch?
I like a good smart watch and I appreciate open source, but an ESP32 isn't a great pick when low power consumption is important and the device is going to be communicating regularly. I'm surprised LILYGO went that direction in a watch form factor.
an esp32 on an 1100mah battery will last years on deep sleep, and about a day with wifi on and in high power modes.
a pixel watch 4 says they last 30 hours , ambiguously. they use a battery less than half the size. in reality with constant use they'll drop dead in 6 hours.
the thing is clunky and heavy , anyway -- so if it lasts as long as an off the shelf watch who cares?
also, the primary reason : lilygo shoves ESPs into everything.
Yeah one of the Nordic nRF chips would be nice. But I guess the advantage of ESP is the hobby developer community. It's not going to be as good on battery power but the barrier to entry for people wanting to tinker is really low.
No mention of battery life? I guess it depends on the software that you run. But it would be nice to have a benchmark for how long it would last in normal watch mode.
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 apps, and just about everything else to be anti-features. There are no devices that really cover all this that I've found. A few Garmin and Amazfit/Zepp devices come close, but they have enough drawbacks for me to not be happy with them. The new Pebble is nearly perfect, but the lack of an O2 sensor is a dealbreaker for me :(
Well as a pebble evangelist I have great news! The heartrate sensor on the PT2 can also do O2 monitoring, they’re planning on implementing it in the future :)
Does anyone know if this has an accelerometer? I recently got a nice sports-oriented smartwatch (non-Garmin), to use it mostly for rowing, but it doesn't track the rowing-rate. It should be pretty easy to program one if the watch has accelerometers, but couldn't tell from the spec sheet (maybe that means no?)
Now we are talking! This one, in addition to all the other alternatives out there, makes the new Pebble dead on arrival. At least at the current price point.

Regular DYI watches aren't big news...
(I would be over the moon for a DIY smartwatch with zero AI and e-ink screen.)

I have one, its a bit bulkier than I'd thought it would be, but its a fine piece of timekeeping ..

I build mine from scratch, including the PCB and a 3D printed case.
For sure, that's not at all the same level of customability, programmability, capacity, nor quality. But It is really a DIY one.
