Re: New Tool Idea

I wonder if the Kinect or the Leap might be helpful in implementing this idea.

Re: The Geek Group

Tim, I've exchanged emails with Chris Boden at The Geek Group and he's really very supportive of DIY book scanning. I happen to know of a commercial book scanner in town and we've talked about maybe getting the company that owns it and is not using it to donate it. In the meantime, I think that a Gr...

scanned books repositories?

Hello all, As we all know, scanning for redistribution of copyrighted works is a no-no. But there is nothing unlawful about scanning works that have entered the public domain (or gaining permission) and redistributing them. I am aware of several repositories of free (as in freedom) ebooks. Gutenberg...

Air Platen Thoughts

In another thread ( http://diybookscanner.org/forum/viewtopic.php?f=1&t=863 ), TomHorsley said: In my imagination, I have this device that drops a post-it wrapped "sausage" on the edge of the page, then rolls it a bit, so the weight holds the pages down... In my air platen experiments I used Teflon ...

Re: Lever Actuated Platens

I wonder whether the sliding/nested PVC pipe would admit a pneumatic/hydraulic approach. Remember that idea using a turkey baster to push the shutter? Perhaps a bellows with a LOT more volume would work with a foot-pedal to lift the platen. Anybody got an old pump organ laying around?

Re: Clemd's DIY build in photos

Clemend, I though you got your monitors from He-Who-Should-Not-Be-Named, aka Univershul? Ha ha. Yeah, that's him, he has a new identity. It's the address he used when he signed up here the second time (which didn't go as well as it might have). I still want to keep that unfortunate situation out of...

Re: K'ichee' book digitization

since that background is a repeating pattern, couldn't you do some kind of 2D blind deconvolution to subtract it out?

Re: Methods To Sense The 3D Surface/Structure Of A Book

Sorry to ask an ignorant question... When I see the flattened images, I still see the shading gradient. But it appears that you all have an estimate of <x,y,z> of the paper for every pixel in the image. It seems that you can estimate the angle of the paper with respect to the illumination source, by...

Re: Bindery

I LOL'd at this, for real. I noticed recently that there are certain situations in which ANY TEXT AT ALL is the MOST INTERESTING THING EVER - like (when I had hair) reading the ingredients of shampoo in the shower. Sodium Laureth Sulfate? SO INTERESTING. Well, this may be my most OT comment ever. T...
