Low power clock with e-paper display and MSP430

This project is a proof-of-concept for a low-power e-paper clock, using the display of a Motorola F3 and the MSP430 Launchpad.

A few notes on the video:
* The timer was actually sped up by the factor of 10 for demonstration purposes, so 1 minute on the clock is actually 6 seconds in the video.

* Completely powering down the display also has its disadvantages. As you can see, the display needs to be initialized every time you power it up again (thus the flickering), which isn't needed when just disabling the 32KHz clock.

* The second row (showing 000000) is just a counter, counting the total hours the microcontroller ran, intended for a runtime test with a goldcap or CR2032 battery.

Nice work! I have one of these phones, bought in Germany, but now back in Canada. It's hardly worth paying to have it unlocked so I can use it here, but this could be a great new life for it!

Love the video! There is a small error in the narration though. The first time the current draw from the pull up resistor was described it was "80 micro amps" and the second time it was "80 milli amps". It made me watch the video a few times just to make sure (not a bad thing really).
