Do-It-Yourself book scanning is using cheap, compact cameras and free open source software to scan books quickly and efficiently. DIY Book Scanners can be as simple as a camera and a piece of glass PDF or as involved as the Instructable that brought our community together PDF / Vimeo. Today the DIY book scanning community has GPL-licensed laser cut designs, aluminum designs, and detailed instructions for beginners. They have built hundreds of scanners and freely shared thousands of design improvements.
This type of technology is useful to the OSAT community to digitize out of print appropriate technology books, wikify them, and then share them here.
