A small, credit card sized ARM based computer, Raspberry Pi has seen tremendous response from developers all across the world. This talk is divided in two parts: 1.Raspberry Pi: Getting Started with Python and tools In first part I will brief about raspberry pi, its features and will discuss how scientific computation can be done using small raspberry pi.I will also discuss what tools are needed for the same. It is followed by examples in key area like data processing. 2.Controlling external device using Raspberry Pi and Python In second part of the presentation I will talk about one specific project. Data is entered by user and the complex processing (project specific) is done by python. Based on the result given by python code Raspberry Input/output ports can be controlled to control specific device connected to it.
