I'm Bruce Freeman and will show up various places as freemab. I'm a member of IXR, a makerspace out of the InfoAge Museum in Wall, NJ. We are interested in making a book scanner. We may start with the cardboard box-type scanner as per Instructables, but there's interest, at least, in making a "more professional" device.
But my question is whether there are currently ANY other plans available for ANY scanner designs. So far I have not found any on this website, but I've only begun looking.
The design using laser-cut plywood would actually be a disadvantage to us because we don't have that capability. By contrast, we are quite capable of fabricating a steel frame, and I would prefer to go that route. However, we've decided at least to work up a cost estimate for whatever is "state of the art" in DIY book scanners.
BTW, the bungee cords in the video strike me as NOT the way to go on the book-lift. I'm not ready to propose a particular alternative, but I've "levitated" hammers of 16# to 55#, so a book would be easy. If somebody would point out the appropriate place to discuss these things, I'll contribute there.
This is also the wrong place to discuss design details, but maybe somebody can save me time by pointing out where I'd find more info or discussions on a few other topics:
* Use of polarized lighting to reduce glare.
* Use of museum glass to reduce glare.
* Use of low-inertia optics to photograph both pages with a single, centrally-mounted camera.
* Any work on a balanced book-inverting device (for a camera mounted below the book), preferably incorporating automatic page-turning.
