This adapter allows you to securely attach almost any phone to almost any microscope for capturing still images or video, or for use as a digital display.
After
...Plus several iterations and much testing, I came upon this design. The deep eyepiece clamps allow for focus adjustment, as the optimal distance from a phone camera to a microscope eyepiece can vary. The disconnected eyepiece clamps allow for adjustment to fit a wide range of eyepiece diameters. Lastly, the sliding phone supports allow the adapter to fit a broad range of phones (pictured is a Nexus 4, though larger or smaller phones also fit).
I designed the adapter myself, tested it along with my PI, and borrowed the 'knobby knob' from Thing #26752.
