Settling down into the madness that is IISc, but had to complete a (somewhat tiny) report for my final semester here in JSS college, Mysore. It is an account of theoretical and practical issues and experiences that one should consider while trying to design something which has to be used by others. It’s main focus is on rural areas and LED lighting, but I believe that the principles are quite general in nature. The interplay of science with everything else is quite obvious in this report, if somewhat implicit since that was not the main focus. You can find the report here and the slides here, or check out the documentation section.
