I had some lenses from various sources sitting around and wanted to devise an easy way to use them with my camera phone to take magnified pictures and videos. At first, I just had small metal bezels that I used to hold the lenses up to the camera lens. This was clumsy and upon getting the camera close enough to focus, all of the light was crowded out. These are the problems I intended to solve with this device. This is what I came up with.
Mine is built specifically for the iPhone. However, you can adjust the design to fit the phone you have. I am aware of the magnification apps for the iPhone that use digital magnification. They do not achieve the same magnigication strength and clarity as optical magnification.

Step 1: You will need:
Drill (drill press is best)
Jar lid (I used a lid from a pickle jar)
Lenses (from scrapped cameras)
3/4" Suction cup
Rubber O ring that fits around the "mushroom" part of suction cup
JST Connector (scrapped computer)
Small piece of extra wire
Switch (AM/FM switch from old walkman)
3v battery holder and battery (scrapped computer)
Hot glue or silicone
All of these materials (except the glue) were easily scavenged. I have a case on my iphone. Many cases leave a hole to reveal the Apple symbol on the back. This makes a perfect place to consistently attatch the suction cup in the same place, but I had a hard time finding the perfect sized suction cup to fit that hole so I ended up buying a pack.
