Many a times we in the industry, limits ourselves due to overwhelming nature of the proprietary items combined with lack of money to do the renovation and modernization works to upgrade these old yet working systems.

The broadband Internet that you use in your house for 24*7 might be costing you around $9 to $35 per month , add another $150 (one time ) to it and you have your own home surveillance system which will monitor your home 24*7 from a strategic point inside your home which you can watch 24*7 from Internet while you are away from your home. What more ? in case it senses something unnatural, it will capture a snap and then sends it all the way to your email. You can even order it to serve some older snaps or you

Raspberry Pi distance measuring robotics - Blind man's aid For Games, Microsoft Windows is king, for networking Linux or Unix is king but for small scale automation where power consumption is a major factor, Raspberry Pi has got a place now. Arduino can do to a certain extent but Arduino is a mere microprocessor, it can be a perfect slave but not a master like Raspberry Pi. Raspberry Pi can monitor, administer and can also execute.
