Step 1: Prepare the Bottle

Start by drilling a hole in the top middle of the pill bottle cap big enough for the camera to see through. Then, drill 2 holes in the pill bottle: one in the bottom on the outside, and one on the side near the top.

Step 2: A Bit About Lenses...

I used a lens from an old camera I have, but there are many smaller lenses that you can use, just so long as it magnifies.

Step 3: Fix the Camera

The camera I used included six infrared LEDs that very annoyingly lit up my objects so I couldn't see them very well. So, I decided to open the camera, remove the LEDs, then close up the camera again. NOTE: Now is a good time to check the manual focus on your camera by holding it up to your lens. I had a camera that the lens on the camera was a focus for the camera. I held the lens up to the camera, and spun the focus until the picture was clear. If you take the lens away, the image will be fuzzy, but it will be fine when you put the lens back up to it. 

Step 4: Install the Lens and Camera in the Top

Glue the camera into the pill bottle top so that it can see through. After, glue the lens to the top of the pill bottle cap.

Nice work. I wanted to get one of my son's a microscope for Christmas but they were too expensive. May have to build one of these for him. Thanks for documenting the project.
