SmartHome.... high availability architecture... but just for fun and to play with some technologies. The system is also able to run on a single system like the "Scada Local" system, and this is just an old Lenovo Netbook with 2GB RAM...

Mobile-Phone-App: http://www.rocworks.at/wordpress/rocvmobile/

Used software: Arduino, RaspberryPI, WinCC OA, VMWare ESXi, iSCSI-Target TGT, Oracle-Solaris, Oracle-Linux, Oracle-Database & ASM, Oracle-Apex...

Progamming the Arduino was pretty cool, this cheap micro controller is very powerful :-)  Implemented a rough interface to WinCC OA (powerful SCADA software made by Siemens/ETM)...
