Re: My new "Tower" Scanner

Wow, 15 X 15 is a big scanner. Good luck with it. I determined the camera position by trial and error. I built the mount so that the center of the lens was aimed at the center of the platen. Then I slid the camera up and down until it just covered the area I wanted to scan. I did this with no zoom o...

Re: Patents

I don't know much about patent law, particularly in Israel. However, I will make a couple of observations. If anybody has patented the V platen configuration I don't think they can enforce it. It has been too widely used by too many people and if it was patented the patent owners have not enforced i...

Re: Flat Platen

A piece of flat glass or plastic that you could lay on the page might be all you would need. I don't know how your scanner is built, but it might be a fairly simple arrangement. Pressing it down might be the tricky part. A simple frame with a handle might be all you would need.

Re: Clean your camera lens

I now clean it with a microfiber cleaning cloth every time I start to scan a new book. I'm sure that there are people who really understand cameras who could answer the question better. The major thing about camera lenses is to clean them regularly and to be careful not to scratch them while you do ...

Re: Best camera for scanning?

I don't thing there is a "best" camera for scanning. Almost any camera with a decent resolution will work. More important is how you plan to scan. Are you building a 2 camera scanner or a 1 camera scanner? For a single camera scanner you will need have a camera with a good resolution (about 2 megapi...

Clean your camera lens

While editing the text from the book I am currently converting I found that the lower part of the original page/image was not in very good shape. It had a lot of errors. I checked back to the original images and there seemed to be a glare on that part of the page. I checked and checked to see what w...

Re: How to crop and deskew pages using only free software?

I don't know about software to do it, but could you zoom in tighter so that you mostly get the pages, and not so much of the surrounding mechanism? I think my OCR (ABBY Finereader 14) could handle that.

Re: Please recommend paper cutter

The type of saw I suggested comes with a variety of blades that can be used for many purposes. I mostly use mine for wood or wallboard, although it is one of the first things I think of when I need to cut something. The fine blades can do a very fine cut. It is not a circular saw. The blades oscilla...

Re: Please recommend paper cutter

I don't do cutting myself, but I'm not sure I would bother with a professional paper cutter. I would most likely use a saw. If you rig a clamp with a couple of pieces of wood, or maybe angle iron would be better, then you can use that to guide a fine toothed saw blade, manual or powered, along the s...

Re: WTB or Rent DIY Scanner in Southern US

It is a lot easier to buy ebooks than it is to scan them. I do that for books I can buy. But I have a lot of books that are not available as ebooks. If I check on line and can't find them I go ahead and scan them, realizing that if they do become available I am honor bound to buy the ebook. I have h...
