Re: Automatic Page Turning

I'd be very interested in learning about any experiments on an electrostatic page lifting mechanism. I think such a thing should be possible and perhaps gentler on the paper than a vacuum or other mechanical page lifter. I think using static to pick up paper is interesting. Applying a controlled am...

Re: Automatic Page Turning

Because I was planning to poke a rod into the gap of the lifted page. Thanks for pointing that out. Before I had imagine a stick poking out half a circle about 2 inches near the gutter, but it appears to poke out more than 2 inches starting from the end of the book and keep going beyond the book gu...

Re: Automatic Page Turning

(1) hold the pages down for the camera shot,...I think that it "may" be possible to hold the pages down with vacuum That is a neat idea. But it might get real complicated or complex as the book dimension or position changes. The complication may lead to an unfinished project. :( An elegant solution...

I think this is a good idea but could it work on thin papers like phone books?

Re: Flat Bed Scanner

That isn't my scanner but I made one just like that about a month after that photograph was made. At that time I didn't know it was a similar design. I scrap that design after a couple of days when the quality wasn't good enough and Scan tailor had showed up. It was also a bit difficult to get the b...

Re: Please VOTE - Help Establish A Digitizing Facility

I once had the same dream as John K - to provide people with access to otherwise inaccessible materials. I soon realized that those giving the grants have strict requirements. They require proven technology that they can see and touch. They won't allow you to go on your own unstructured path. From m...

Re: Flat Bed Scanner

The cold cathode light source. I have seen this made into a external light. Is this worth making? I currently use 100w CFL bulbs. You can salvage the light and hook it up to the back of your contraption like this image. http://www.diybookscanner.org/images/thumbnails/build_by_adampadsadam.jpg These...

Re: Search SUCKS!!!

I found only one page with "lights source" "plate." I think phpBB doesn't do quote searches. Instead, I use patience and also use the browser's search function. ...when the light source is 45 degrees... ...that will change to a mount plate - again, ... http://www.diybookscanner.org/forum/viewtopic.p...

Re: Suggest improvements to the site here.

1.) Video is something that is now a standard part of the web these days due to the fact that most users are now on high speed connections and almost all digital cameras are video capable. Is there a security risk for allowing users to embed Youtube videos? I mean only allowing embedding specifical...

Re: When the Internet and all Electronics Hard-Reset

A complete shutdown of all media and electronics, in my opinion, is a good thing. We will have some quiet time to look into our spirituality and begin to grow food in our own backyard and not depend on large industries. We will begin to work together with our local neighbors to create a new, sustain...
