This is a quiz buzzer system supporting a maximum of 8 teams. It uses an ATMega8 microcontroller unit to continuously read the state of the buzzer switches, find which team pressed the buzzer first, and display the appropriate number in the seven segment display.

I just decided to write a Python script to convert resistor color codes to resistance values. Later, I also wrote a script to do the reverse - namely to find the color code of a given resistor.

This is actually a set of two "applets" we did as part of an assignment for "Signals and Systems" in the fourth semester of college. The goal was to write an application which illustrated basic signal operations such as shifting, scaling, folding and also signal addition and multiplication.

This "matlet" is work we did for an assignment we had in the third semester on Electromagnetic Fields. The problem statement was to create an applet which could plot surfaces in the spherical coordinate system.

This is a loose collection of programs we wrote as part of a course on "Stochastic Models" we had in the fourth semester of college. This includes a couple of pseudo random number generators (the Von Neumann middle square PRNG and the linear congruential generator PRNG), an implementation of the Monte Carlo method to determine area of an arbitrarily shaped figure and a simple simulation of birth-death process.

Sudhakar and I did the coding at the end of our first semester in college (actually, during our semester examinations!). We just wanted to kick start our entry into AI programming and thought teaching the computer to play tic tac toe might be a good start. We may do far greater things, but this is the first proper project we did and hence we are obviously proud of it!

Now, unless people really start understanding the underlying environmental issues, and take action, nothing is going to happen. It is time to be self-reliant, find our backbones, and get started shaping our own futures. A much better idea than depending on spineless governments, methinks.

Stallman was here in college today. Having watched many videos of his speeches from the Internet, and having already been involved with the Free Software Movement, I didn't really have too much new stuff to learn from his speech. But, needless to say, getting to see the man in person, and actually attend one of his speeches, was not an experience I was going to miss out on.

Suppose fractal antennas which can operate in the visible light region could be designed and fabricated, we could have fractal antennas on top of all buildings to absorb solar power instead of using solar panels!

If the universe was all laminar flow, and if God was the stirrer, could he just reverse time by stirring backward?

It is true the average classroom is a really boring place to be in especially when the teacher is unable to effectively deliver the content. And when students find that their questions don't get satisfactory replies, they lose interest and enthusiasm. But there is also another important factor involved - the Internet.
