tl;dr a diy system for scanning books. Basically, build a triangular prism with a special zig zag slit for a single page to snake through. Put a vacuum on each side to pull the paper through the slit. Put two optical scanners in the middle of the slit, to scan both sides of the sheet as it hangs down. Attach a motor to move a sled pushes just the top, then bottom, of the book. The site features six designs. Some include videos of operation [0].

I check etsy every couple of years and haven't seen someone offer a kit. I use 1dollarscan, though they've had to restrict their offering as Pearson, et al notice their existence.
