Scanning your own books is so 2010, but those of you who are living in the past are probably going to get a kick out of the following scanning rig.
An engineer at Google has just released the blueprints for his book scanner. Dany Qumsiyeh started working on this design because he wanted to find a cheaper replacement for the multi-thousand dollar rigs often found in major universities which was at the same time less labor intensive than other DIY designs.
I've seen several of the more expensive models but they have always been well outside anything I can afford. Dany's design, only costs around $1500 in parts (Macbook sold separately). It can scan 2 facing pages at once, and after a pair of pages are scanned the book is pulled over a vent which is designed so the vacuum can grab just one sheet of paper and turn the page.
All in all, it's a pretty sweet rig. It's even more fun to watch it in operation.
