Turn your iPhone into a high-power digital microscope for around $10
Pathology resident here. I really like this hack, but a fair amount of my work is at higher magnification, and requires much better correction. However, I have been very impressed with the magnifi by arcturus labs. If you already have a scope and just want to take pictures, I highly recommend it. I can take better pictures with my iphone 5 and my magnifi than some folks seem to be able to take with their far more expensive dedicated cameras. http://arcturuslabs.com/Not a shill, just a very satisfied customer.Also, check out http://reddit.com/r/pathology for lots of what-is-that? pics!
