Raspberry-Pi book scanner. I needed a way to scan pages of a book without destroying it. Normally I remove the book cover and then use a paper-cutter to get individual pages that are scanned with a ScanSnap scanner to get the best images. Sometimes, I need to scan a book without cutting it up or even opening it up fully to place it on a flatbed scanner. I used a Raspberry Pi low cost, credit-card sized computer and a camera to create a book scanning station. See the project and the photos here.
