Cellphones might come with some really high resolution cameras these days, but that doesn’t mean they are great at macro shots. Aydogan Ozcan, an assistant professor of electrical engineering and member of the California NanoSystems Institute at the University of California, Los Angeles, has come up with a DIY design for a cellphone microscope, writing his very own software to work in tandem with off-the-shelf parts that cost no more than $10. There isn’t any lens to worry about basically, as magnification will be handled by the software, holograms and electronics.
