Server Setup
---

  * Install MagicMirror on localhost, for example in Docker: https://magicmirror.builders/
  * Install modules, for example a slideshow: https://github.com/roramirez/MMM-ImagesPhotos
  * Configure MagicMirror and its modules, for example as in `./magicmirror/config`. Avoid transitions and colors.
  * Customize the CSS, for example as in `./magicmirror/css`.
  * Install the dependencies of `./magiccapture` and Chromium.
  * Make sure that the URL in `./magiccapture/index.js` points to the MagicMirror address.
  * Set up a cron job to run `./magiccapture/run.sh`.
  * Use a web server and make `./magiccapture/screenshot/screenshot.png` accessible to the network the Kindle will be connected to.
  * Start MagicMirror, run the cron job and verify that a black/white PNG is being served.

Kindle Setup
---

  * Get a Kindle 4. This setup was tested on firmware 4.1.3.
  * Install the jailbreak and USBNetworking, the screensaver hack is not needed: https://wiki.mobileread.com/wiki/Kindle4NTHacking
  * Install the MKK and KUAL: https://www.mobileread.com/forums/showthread.php?t=203326
  * Move `./magickindle/` to the Kindle at `/extensions/`.
  * Change the URL in `./magickindle/bin/start.sh` so that it points to the web server.
  * Optionally, customize the `rtcWakeup` time. The length of the interval has a significant impact on how long the battery lasts, as the Kindle only consumes power for the one minute wakeup.
  * Navigate to the KUAL application on the Kindle and start the Magic Kindle extension.
  * Press the power button to activate the screensaver which triggers the Magic Kindle script.

Enclose the Kindle in a fitting photo frame. Charge it once a month. If it does not turn on, press the power button for a minute and press it again for 10 seconds to force a reboot.
