Hats off to these students. Great job under time pressures and in realities of an environment in which one can't just spend your way to a solution. If only more people spent time building useful things like this instead of yet another cat monitor, new ways to waste more money without leaving the house, and other non-life-enhancing trivia. The collective skills out there are almost unlimited.....especially the incredible people who post and comment on HN. Please everyone reconsider the uses to which you put your amazing abilities. Code could change the world if we built more useful things, less blogs, less shopping carts. Closing point.... Once a project is dealing with hardware it's 20x harder. But the outcome is better. In code as in life, when faced with easy choice or hard, always take the hard one. It's how we grow as people and extend our skills.
