InkWatchy

A firmware written from the ground up for the watchy and now also yatchy

Getting rusty🦀 and better looking with slint

Demo video previews here

User features

• Easy to install demo (no compiling!)
• Modular and configurable, a lot - if you disable a thing, it's not being compiled, it's like it was never there
• A lot of watchfaces
• Language Support: No perf/binary compromise: fully-validated EN/PL + less-tested DE/SK/IT
• All the regular goodies you would expect from a firmware: timezones, time drift compensation, NTP sync etc. (in one form or another)
• Full weather info via open meteo api in charts, 16 day weather forecast, 5 days of air quality + on watchfaces
• Calendar show of events, their time and description from an ICS file (So any calendar should sync)
• Alarms
  • Basically unlimited ammount of them
  • Quick alarms setting
  • Pomodoro timer
• A book reader
  • With pages changable by moving your hand
  • Support for many books
• Interactive watchface by using watchface modules (Apps which are shown on the watchface directly).
  • Bitcoin module, with a "Big" mode to be truly a "bitclock"
  • A simple network module
  • A small conway game of life module
  • Image gallery module
  • Calendar module, to view the nearest event
  • Book module, to view the book text all the time
  • Alarm module, to see when the next alarm rings
  • Api module, to send button presses over the network (experimental)
• Debug menus to check on things on the fly (for example, a 3D demo of the accelerometer axis, to check if it works)
• Battery life features:
  • Configurable wake up every x minutes at night, at default it's between 23-06 every 45 minutes
  • A menu to manually, or after certain battery percantage drop enable these features:
    • Disable wake up - The watch will sleep until you press a button, this extremely improves battery life
    • Disable all vibrations - The vibration motor is heavy for the battery
• A "vault" which allows to save encrypted images to the watchy and view them if provided the correct PIN. All generated dynamically via a script. Uses AES128 cbc/ecb. Example use is a backup phone book, bitcoin key backup in the form of a QR code
• Games / Fun
  • Blockchy, a tetris like game
  • Snake (Written in rust!)
  • Pong game
  • Jumper game
  • Dice app, with 3D animation
  • Maze game, Paint - controller by accelerometer
  • Conway game of life
  • Small video player
  • BLE game controller
• Experimental heart rate monitor (Just a proof of concept, works best on Yatchy)

A weekend project and a weekend feature, so it looks like it looks, but works well and does the job, further notes:

• the app is not open source & available to the public (The InkWatchy side of code is) for the simple reason that BLE sucks and I don't feel like supporting every device out there, works for me. If you really want it, well:
  • I won't help anyone with issues with the app, even if you get it by the ways below, you can report the issue, I may fix it, but I don't promise anything
  • Yatchy owners can request it and I will share it, no questions asked
  • Discord server regulars, InkWatchy contributors too
  • Some donations (Not only to me, but to some nonprofit organisations too, specified when the topic appears)

Experimental, but works for me

• Reset cause shower. If your battery will be the cause of a reset, you will be informed about it on boot.
• Stuck button detection & error screen. Perfect when assembling the case or designing a new one
• I integrated https://github.com/risinek/esp32-wifi-penetration-tool to this firmware as a service. I won't provide support for it or give any advice how to use it. Use for your own responsibility, don't do illegall stuff. Seriously.
• https://github.com/ckcr4lyf/EvilAppleJuice-ESP32 too. the same story as above. _{Those 2 options were removed because I updated the build system and didn't bother to make it work with it, with some cmake you should be able to easily re-add those features, I you can't use cmake, then you shouldn't probably use either of those features anyway}
