The FlyPi is an open source affordable microscope (less than 100 dollars for the basic version), that can be used in a lot of applications requiring amplification of tiny things/objects. In our more detailed description (http://biorxiv.org/content/early/2017/03/31/122812) we show applications in neuroscience, animal behaviour, diagnostics and education. Due to the open source aspect of the project, it can easily be adapted to uses we didn't think of, or test yet.
