Editor's Notes
- #2: It is really wonderful to be here at IIT for the first time. Enthusiasm and Eagerness I have seen in students are admirable. It motivates me to work harder and smarter. I am going to talk about Raspberry Pi and how to leverage power of Raspberry Pi in scientific computing.
- #3: I am Samarth Shah , an Electronics Engineer from Ahmedabad. My area of interests include Hardware tinkering , human computer interaction , open source computer vision. I have worked on Kinect and several hardware development boards. I spoke at two national conference about Gesture Recognition and Speech Recognition or in general terms Natural User Interface. I write article for Open Source For You. I am avid writer of motivational and inspirational thoughts & I share the same at my blog https://shahsamarth.wordpress.com
- #4: What you will learn today? You will come to know about Raspberry Pi and its features and how to develop python application using Raspberry Pi. I will demonstrate one specific project of Raspberry Pi and Python to use in scientific computing. Finally we will see some cool hacks of Raspberry Pi.
- #5: What is the motivation behind this? I read about Raspberry Pi few months back. There are four factors that motivates me to buy and work on this device. 1.Tiny Board(weights around 45 grams) 2. Portability 3. Low Cost(It comes in two model: Model A is of 25 $ and model B is of 35 $) 4. Open Source
- #6: What exactly is Raspberry Pi?

- #8: Few days back Raspberry Pi foundation has unveiled new Raspberry Pi store where you can submit your app and you can earn from it.
- #10: What you see on the screen is boot messages. It is like our desktop. There are icons on the desktop like our conventional desktop. Python 2.7 and Python 3.2 are already installed with debian squeeze version and it is recommended for the new-bie user. Example: Numpy module with Raspberry Pi Scratch
- #15: Initially both models ship with 256 MB RAM and because of it in some programs you can see some performance issues. One thing to remember is as it is a tiny computer , there is a possibility that some Python module might not work in raspberry pi. It support many keyboard and mouse but not all. Similarly it supports many LCD but not all. Details of supported devices are mentioned on raspberry wiki page.

- #18: Currently I am working on Image Processing Project: Detecting craters from the image provided by the satellite. In this project I am using OpenCV to do the computation. Moreover OpenCV library can be ported to Python. I am planning to use Raspberry Pi for computational task of the project. Similarly you can use
