So maybe my scans don't need to be nearly as big as I thought. (Although FineReader did pop up a little message saying "Increase scan resolution for better accuracy with small characters." But its concerns were unwarranted since it still recognized everything on your page just fine.)
No, the image size is compressed by flickr. With a free flickr account you can't offer people the ability to download images in their original size. If you want the full images, grab them from here: http://bkrpr.org/doku.php?id=download

Yes, I noticed in the thread you linked to above, about cameras, that an SLR camera with a 2/3" sensor would be much better than a regular $100 digital camera, regardless of megapixel rating. But since none of us want to pay out $1000 for a couple of used SLR digitals, we'll have to see what kind of cheap consumer digital cameras work best.

Oh, and another question: I notice in your video that the book is sitting on a V-shaped cradle. Is that one of the "do it yourself repro V cradles" that ereszet talked about in the thread you linked to? How much did that cost you to build?

Until I saw that video, I was mentally picturing the bookripper device as working the opposite way, with the book lying on top of the plexiglass and the cameras angled up at it. I wonder if such a system would work... or if you really need the weight of the device to hold the book's pages still.
Yeah, we all live with what we have I actually built my v-cradle before I ran into the information here, so it is a little rougher than ereszet's. I just made it from some scrap wood and a lot of angle braces from the hardware store, so it was just a few dollars to build. I've been planning some different designs but it works pretty well as is.

You are not alone in thinking about a device where the book is on top, I talked to a couple of other people while coming up with this design and they also thought about flipping it upside down. Turns out there are a number of issues ranging from the book sliding off to being unable to reach the cameras, but it might be a good idea for a pre-manufactured device, like a scanner.
