Hi, I want to build a wrist watch for people I love using e-ink display, can I get some articles on that? or if someone has built it before and can guide me through it.

I am aware of this https://rebble.io/

Saw this on HN some time back: https://github.com/peerdavid/Watchy

I want to buy a ER-EPM0154-1R, possible in india? Thanks @refined-vegetable-38843, @melodic-crowd-48995, very helpful

You can get a ttgo watch by lilygo from banggood

@creamy-sundown-74328 , I wanted to build one myself, my loved one would appreciate that :), but I will look into it thanks

I like the idea. If you keep a chronicle of your research and journey of building it, it would be lovely to read

I want to build something like this for myself later this year. If you come across some good resources, do let me know.

@crooked-tent-69024 Ah cool, yeah there are lots of modules available these days to do that easily at a low cost. I made one around 6-7 years ago with OLED and ESP8266. https://github.com/shantanugoel/esp8266-smartwatch

hey @victorious-energy-56764, @faint-energy-11966 I will 🙂

I left it out in the middle though (As I do with my all side projects :P) and didn't build the final chassis with lipo. But let me know if you need any help during your endeavors and I can help out. You should mostly look at ESP32 (Can choose from S2/C3 variants of it as well depending on your needs) as that will give you most things together (A good enough micro controller + onboard wifi + BT + ADC + enough SPI/i2c/gpio/battery to connect any peripherals, all in one for an extremely cheap package and small form factor conducive to a watch). Lots of third party firmware/drivers as well and if you want to do your own, it's pretty easy to write. They support micropython and nodemcu as well in case you want to go that way instead of the native C SDK (though C will require much less space and be more performant)

I love esp32, I am using it for building a wifi lamp, :D I am using nodemcu btw. And yes I am using C to do stuff, I want to use e-ink display, I hope the lipo battery isn't giant.
