Step 52: Camera Support: The New Deal.

Picture of Camera Support: The New Deal.
For the new scanner, I happened to have the remains of two Elmo Classroom Presenters. They're usually used in classrooms to project the handwriting of the professor. I found two of these things partially disassembled in a dumpster at my university. The arms from these units are nearly perfect for cameras -- they can be extended, they lock easily, and they have a rotating bit at the top.
