How-To: Book scanner on the cheap

Noah Bicknell and Daniel Reetz made this book scanner using cheap digital cameras and scavenged building materials. From the Insructable:

I love books. There is some truly fantastic knowledge and information hidden out there in hard to find, rare, and not commercially viable books. I find that I want my books with me everywhere. But that’s where the problems begin. Buying, moving, storing, and preserving books means environmental costs… and when I loan a book to a friend, I no longer have access to it. Digital books change the landscape . After suffering through scanning many of my old, rare, and government issue books, I decided to create a book scanner that anybody could make, for around $300. And that’s what this instructable is all about. A greener future with more books rather than fewer books. More access to information, rather than less access to information. And maybe, years from now, a reformed publishing/distribution model (but I’m not holding my breath…).
