The speed is related to the time the camera needs to a) focus and b) copy the photo to the Mac. I still need to make the glass plate; I tried to work without, but the 'scans' need to much manual correction in the GIMP afterwards. 1 second is extremely fast! I believe even the Atiz needs two seconds or so. I get 1 page per 7 seconds using a Canon Powershot A620 and an iBook.

Where could I get more information about your projects? We are looking at similar solutions here in Germany. Looking forward to your posts! I am also very interested in your results.

Those expensive optional equipment like the those offered by 4digitalbooks.com are crazy. I commend you on trying to find a better solution. Keep me posted of your progress I really what to know!

Of course my wrists began to hurt like hell after half an hour--in a day I would probably get irreversible arthritis. So I hired two students to take turns doing 10 minute stints, with 10 minutes per hour doing nothing. I have also assigned each student of my research seminar class to design and build a different working version of an automatic page turner device that works with my existing set up. In about 2 months we will see how things turn out. I cannot understand a world so devoid of local ordinary person building that people would buy nothing and copy nothing or else pay US$150,000 for what can be done for under US$1300 by anyone, even brainless ones like me.
