A Do-It-Yourself Book Scanner

I found an instructable for a DIY book scanner. There seems to be a thriving online community based around building DIY book scanners as well. I have a lot of books I’d like to scan into electronic format. There’s a startup called One Dollar Scan that will scan your books for a dollar. Unfortunately it’s based in the US. It would cost me a fortune to send my books over there to be scanned. A DIY book scanner sounds like the ideal solution for me.
