Today I read an article on using a smart phone as a field microscope: Scientists use smart phones to get the poop on worm infestations. This method has been fairly accurate at detecting certain types of infestations and can be even better once it has been tweaked a bit. This is a great example of frugal engineering and yet another example of how mobile phones can make a huge difference in rural and poor areas.
