Introduction: Super Simple Microscope
This is just a 720 p resolution web cam mounted on a pole. The higher resolution cam you use the better the result will be.

You can use any flat surface for the base and the upright pole doesn't even have to be perfectly square to the base. I used a brass bushing that has the camera mounted on one side and a lock screw on the other. The bushing needs to slide freely when unlocked. I used a thin round piece of plastic to attach to the camera focus wheel just to make focusing easy while the camera is mounted. Just slide the cam up or down until the picture looks somewhat clear and then lock in place and use the focus wheel to fine tune it. Once you have used the software to capture the picture you can then enlarge it digitally in the computer using your photo software.
Here is a shot of a fruit fly without digital enlargement.
The upper picture is a shot of a pencil tip and the lower picture has been digitally enlarged in the computer. The results would be better with a higher resolution web cam.
