Having a go at using my kindle as a clock/weather dashboard

This sort of thing: http://www.mpetroff.net/archives/2012/09/14/kindle-weather-display/

Key think is that I will be publishing images of the time + weather, Kindle will be a convenient display but of course you could use any web-enabled device that'll show an image.

Thinking of using a Pi as the web server but that's just arbritrary too as it'll probably be a pure python web server and implementation.

These instructions are for my Kindle Wifi with 4.0x software. Your mileage may (will) vary.

To have a full-time clock, you need to disable the screensaver. To do this:

1. Go to the Home screen
2. Open up the keyboard
3. Type in (all commands without inverted commas): ";debugOn"
4. Press enter
5. Type in: "~disableScreensaver"
6. Press enter
7. Type in: ";debugOff"
8. Press enter

If you want to revert this change, do the above but type in ";resumeScreensaver" at step 5 instead.

That's it, now you can use the Experimental browser, pointing it at the clock web page and you're done.

Oh, and if you're feeling game, check out "~help" ;)

The "server" is just a bit of Python.

There are two different types of data that I want to display, low- and high-refresh.

Low-refresh:

• Today's weather forecast
• Current temperature
• Number of emails in inbox
• Agenda

High-refresh:

• Time/date

The idea would be to statically generate the low-refresh data on page load. This could be done once per hour via JS/Meta refresh.

The high-refresh data would be done via JS.

The positives of this breakdown are simplicity. A single template with a single block of back-end Python. No need for ajax end-points for async updates etc. JS can still handle the time of course.

The negatives are that I cannot add high-refresh data without having to change the design a fair bit, adding ajax endpoints in my Python. Will deal with that if I have the need.
