iPhone Biosensor Cradle

Your iPhone can do a lot of things, including entertaining you and teaching you new things. Thanks to a new iPhone Cradle created by researchers, you can turn your smartphone into a biosensor. With a roughly $200 gizmo, you will get readings as accurate as $50k laboratory machines.

The kit includes a cradle that contains a selection of lenses and filters with an app for doing analysis. An Android version is being worked on. Pretty impressive all around.
