I'm still disappointed that new smart watch development has seemingly stalled in progress as of late. I was hoping that by this time we'd have watches that had 24 hour battery life, and an always on display that didn't need a flick of the wrist to activate. I hoped that wouldn't be asking for much, but I guess it's harder than I assumed.

I purchased an Amazfit Stratos around 6 months ago. This thing is better than any other smart watch I have owned (Pebble, Moto360, Apple Watch). Always on screen. Multiple days worth of battery. Best workout tracking I have had on a watch. And it does all the notification and smart watch type things I expect. I am not certain why Apple, Samsung, et al haven't figured these things out yet, but other companies have and it is great. Oh let's not forget this only cost me $150.

The DA14683 is fantastic. I played a bit with an eval. board and it's really good for it's price vs. features (~$3 for 250 pcs. at Mouser). But soon the idea of releasing code for it as Open Source faded away, since you need to sign an SLA ( https://support.dialog-semiconductor.com/connectivity/reques... ), that limits the way source code based on their in SDK is released (only to your customer, in an only “need to k…

Probably by ignoring the license.

So according to your logic, lack of apps == gimmicky?

Yes, since you can tell the time with a regular, non smart, watch, too -- and some will also do notifications and other stuff. In fact, even with the apps it's sorta gimmicky. Unless you use it for health purposes (e.g. heart monitoring), a smartwatch is not of the "my life change" category. At best the "I could do the same shit with my mobile phone, now I also have another device for them that I can do them in a wor…

Women's clothes don't have pockets. Always having an active LTE modem strapped to my wrist makes me feel safer. It is easy to be separated from my phone because I don't have pockets.

Even my 3 year old Zenwatch 2 lasts over 24 hours with an always on screen. Watches like the Amazfit Bip last close to a month with an always on screen.

I'm pretty sure FreeRTOS has been open source since its inception in 2003, see posts going back to 2004 at [0]. Amazon forked it, merged their fork with the original project and took over it in 2017. You can read about it here [1]. [0] https://sourceforge.net/p/freertos/news/ [1] https://freertos.org/FAQ_Amazon.html EDIT: actually, I don't think they fully merged their fork as there's a variant called a:freeRTOS

FreeRTOS was previously GPLv2 with a couple of added clauses (anything linked with FreeRTOS is now GPL too and you can't publish performance metrics without approval). I'd imagine there were a lot of companies not wanting to GPL everything they made with FreeRTOS (i.e. Amazon) so with a new MIT license, anyone can do whatever they want.

So they somehow took over a free software project and removed the GPL? That doesn't seem like a positive development!

What a great project! I love how much attention to detail he put in. Fantastic, this is exactly the kind of thing I love studying and working on myself.

Sidenote, I'm a bit disappointed that people use imgur to showcase their projects, as I don't think it's very good for that. I built https://www.makerfol.io/ for this exact purpose but people seem to still prefer imgur for some reason, and I'm not sure why :/

That thing unfortunately seems to have died with Pebble.

Amazfit is the closest player to Pebble's old space. I don't think they have any 3rd party app ecosystem at all, but the baseline experience covers time, notifications, workout tracking, and a couple other things.

Bip and Stratos are the watchier lines, they also have more minimal Fitbit strap-style product that I forget the name of.

EDIT: Here's another new entry https://arstechnica.com/gadgets/2019/04/garmin-revamps-entir...

> Like most Garmin smartwatches, the Forerunner 45 and 45S track all-day activity and sleep, deliver smartphone alerts to your wrist, and are easy on the eyes thanks to an always-on, sunlight-friendly display. Even though the Forerunner 45 watches are the most affordable of the bunch, they still have a heart-rate monitor and built-in GPS, so users can make outdoor runs without the help of a smartphone.

> It can also connect to external sensors like a running dynamics pod and heart-rate chest straps to capture more running data while you train. The Forerunner 245 watches have the same one-week battery life as the Forerunner 45 watches do when in smartwatch mode, but they'll last up to 24 hours in GPS mode or six hours when using GPS and music playback simultaneously.

That looks really promising.
