Does anybody knows about something similar ( open hardware/source ) in the fitness watch space ? with a HR sensor + GPS ? I really like my Garmin, but no so found of sending them all this health related data...

Please this! I'm in the market for a replacement, but I hate the idea of paying a premium for a device that's still tattling on me.

Surely the real trick is to activate it blindly with your hands under a table or whatever? (Yes, also with a delay so you can have your hands visible when you get the call)
How often are you little in this situation that you need a fake phone call...?
Even if it never happens, it is still fun to think about.

#125Wow, this article doesn't do it justice. Watchy is an open source hardware device that uses an e-ink display and has an ESP32 module builtin [0]. SQFMI, the creator of watchy, has a twitter account [1] which has some very nice screenshots [2] [3]. Even the CrowdSupply website has better pics of the device [4]. This is one of the few watches I've been sorely tempted to buy. [0] https://github.com/sqfmi/Watchy [1] http…
There is also a new Watchy community on Discord here: https://discord.gg/uKcfZZa2 For those considering purchasing - as a Watchy owner - if you're looking for a polished smartwatch product that you can put on your wrist and not think about how it works - this isn't that product. It's still rough around the edges, uploading new watchfaces takes some work, phone notifications aren't implemented yet, no case, etc. But i…
e-ink is a company, it's a Active Matrix Electrophoretic Displays (AMEPD).

Can’t speak to its goodness but lilygo on banggood mentioned in another comment has mic and looks compelling
Looking up the "LILYGO® TTGO T-Watch-2020" and it does not seem to have a mic.
There are several versions with confusing names. V3 has the microphone. I think V2 was never mass-produced. Differences can be found in this table, which also links to AliExpress item listings: https://github.com/Xinyuan-LilyGO/TTGO_TWatch_Library#-versi...

Except for e-ink, why should I buy one, instead of this "polished" one:

(i need a new gadget to play with, a watch seems a 'fun' choice, not affiliated with anyone, I just order a bunch of crap from aliexpress)

#128Maybe I'm a curmudgeon, but I have subzero interest in smartwatches, even hackable or open source models. I want my watch to tell me the time, and I want it to do so 10, 20, and 30 years from now without having to fiddle with software. I love Linux. I cut my teeth on it in high school after one too many viruses on Windows XP made me bite the bullet and try debian. I love my Raspberry Pi. It went from retro-gaming con…
>> My Seiko automatic Bah, a real curmudgeon would have said a £10 Casio quartz :-) I flick back and forth on this. The features i actually use on my Apple Watch: 1. it extends phone battery life[1] 2. I'm UK based but i work with colleagues across APAC & NA - in 3 of the corners of the "infograph" watch face i have NYC, Mumbai & HK times, it shows the city, the 24hr time & handily the offset - i use this all the tim…
I agree. I get way more out of my watch that I initially expected.

#129I have a couple of the £30 LilyGo 'TTGO T-Watch 2020' ESP32 based 'watches'. Lots of fun to tinker with and has a colour TFT touchscreen which introduced me to the very impressive lvgl library to create UI. But the battery life is not great (though that teaches you how to write and use deep sleep modes). An e-ink display would naturally help with the battery life, but the screen refresh times can be an issue for some…
I also got one of those, unfortunately the V1 which doesn't have the microphone. It has a decent feel to it, plenty of features packed into small form and decent amount of open source support.
Hardware wise, display and touch sensor is quite good and I was surprised that I was able to type with 90% accuracy on a tiny qwerty keyboard. The tiny speaker is very low quality and not really usable for speech. There's also a vibration motor, acceleration sensor and IR transmitter (not sure if it can receive, schematics are not available).
I was disappointed by the battery and even more with clumsy charging (micro USB with plastic cover) that I could not see myself using daily. The documentation is very thin and the digging soon hits docs written in Chinese.
I enjoyed the blog post that walks through watch's hardware and brings it to life: https://nick.zoic.org/art/lilygo-ttgo-t-watch-2020/
Community is fragmented across C / MicroPython / Arduino / Scratch environments, as well as across different variants of TTGO watch. It's not too hard to find examples online, but putting them together into something useful takes time and effort.
I chose T-Watch over Watchy because the touchscreen should allow for far richer interaction than 4 side buttons. On the other hand my watch is at the moment loaded with useless and too slow firmware that hangs after few minutes of use. I purchased the T-Watch without any delusions that I'm getting a functional watch. It works well as an isolated handheld ESP32 development platform.

Are there any other companies besides E-ink Corp that sell ^AMEPD^?
