I had an old Tolino Shine E-Reader lying around that I did not want to throw out just because I did not use it anymore. After I found out it ran on Android and there is a way to root it I new I had to give it a new life. So I rooted it and created a mini-app that regularly pulls the current weather conditions and displays them. Furthermore I included a button to show current departure times of public transportation around my flat.

As you might know the Arduino does not have a lot of memory. So parsing current JSON APIs might be a big pain in the *** or would simply not be possible – e.g. due to unsupported https connections. That is why I have installed a separate Google App Engine instance which does all the hard work and only returns the small data chunks I really need on the Arduino.
Of course security is always a big issue when it comes to home automation. All the data is transported on an unencrypted standard http connection. At the moment I can cope with this imperfect approach.
This is the first project I moved to the Arduino browser based IDE codebender. It really helps me to save plenty of time as I do not have the hassles of setting up the Arduino IDE with all the proper libraries. Perfect for people who tend to experiment a lot or switch their dev. machine too often :)
