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.
