This is a SO beautiful watch I ever made~ A lot of animation were used. But this is only the prototype edition, I hope you'll like it (Of course I will give a updated version!!)

I cut a lot of features, because there is no more space for me to burn the firmware into the board(32U4).

Now you can check your time and calendar there, a stopwatch is included too~

A NOT-SO-USEFUL flashlight is also there, ignoring the brightness of OLED is not so good.

The original and reference one is: http://blog.zakkemble.co.uk/diy-digital-wristwatch/, Instead of writing the codes in avr-style, I adopt his avr workbench into a arduino solution, so every one can download the codes and upload hex to his own hardware easier!

First, The not so smart Xadow smart watch is a "Watch"~ I use a RTC module so this won't lose time if it's out of power (Forget the time on the picture, only for testing)
There is a beautiful animation when the seconds plus+ ^_^

other functions:
  1. You can set up the current time~
  2. Enter "stop watch" mode and start timer!
  3. Sleep mode help to save battery power
  4. Calendar mode
  5. Flash light

Step 2: Materials & Tools

  1. Xadow main board
  2. Xadow RTC
  3. Xadow breakout
  4. Perfboard
  5. Buttons

Notes:

There is no button module on Xadow, so you have to use Xadow breakout and Perfboard, together add three more button presenting left, confirm and right.

Step 3: Software

Picture of Software
I publlihthe code at https://github.com/xhbang/Xadow-digital-watch under GPL license, it's totally free and open!
If you are familiar with Arduino, you can make a watch now! Please mod a better looking beyond my design!

Please download and report bugs to me .THX Zak for his initial work!
Hahaha I like the 'girl sensor' idea :D. Haha you could also put a fake 'heat' meter :P
