Current Sinking & Current Sourcing Tutorials

I have seen some web pages defining that current sinking and current sourcing are same. But the truth is that they are different. This is a tutorial about current sinking and current sourcing in Integrated Circuits(IC).

Free Software Summer Training 09

Wanna get some cool training on Free software topics like How to do free software projects, Tutorials to use GIT , RPM Packing ? Then come to the online IRC summer training from Linux User Group of Durgapur (http://dgplug.org)

Entry is free. Just log on to the IRC of DGPLUG
#dgplug on irc.freenode.net

You can find more details on
http://wiki.dgplug.org/index.php/SummerTraining

All these training of this year are done by Shakthi Kannan (mbuf).

Time Table of these training are in the Summer Training page.

Just go through the class logs of the classes conducted last year and find out how effective it is.

Try to come for the IRC chat according to the time table given. I am sure it will help a lot.

Special thanks to dgplug for conducting these kind of online classes.

Experiments using octave for B-Tech course

I am a B-Tech student in University of Calicut, Kerala, India.  The lab syllabus of final year electronics engineering contains “Experiments Using Matlab” which are a set of three experiments to be done using Matlab.  In our college we are using Matlab.  Since proprietary softwares like Matlab are not recommended in universities (see this Why schools should exclusively use free software),  it is goodto use free software Octave.  As I am a free software enthusiast,  I love using octave instead of Matlab.

If I ask the lab staff to use Octave in the college lab, they will ask me “Will all programs work in  Octave?”. Actually they are not happy to accept Octave because it is not mentioned in syllabus. Is it compulsory that students should learn only what is in the syllabus? The other true fact is that, at the end of semester there will be a lab exam. The teachers coming from other college won’t be familiar with Octave. So when they see Octave, they will surely ask to install Matlab.

One of the method to bring free software in B-Tech course (not only in  B-Tech, but also in other courses) is to have a syllabus review. Thereby all will start using free software. If the syllabus changes there should be reference materials for these free software tools. The first thing everyone does if he/she doesn’t know about something is that he/she will Google it. So I thought of contributing once again to free software by writing some tutorials for Octave that can be helpful for implementing free software like Octave in universities.

These all led me to write this tutorial. This tutorial is about installing Octave and also contains some examples using Octave. I have tried to write the tutorial in a simple and lucid way. Hope this tutorial can guide university to use octave in their labs instead of Matlab.

The tutorial here explains the simple example code that can be used for  teaching Octave. This tutorial is specifically designed for University of  Calicut in India. But I hope the syllabus will be almost same in other  universities also.

The tutorial is in my Wiki page. You can visit the tutorial from the link below
