Re: Ugly but efficient scanner made from scrap...
Hi Konos,
This is just a Samsung PL210. It's about six years old now. Shoots at about 14MP. I'm actually finding the images better for OCR than the DSLR. I had to downsize the DSLR to get decent results but now I don't have that problem.
This file went straight into scan taylor, rotate, find page, deskew, find content, adjust margin, output at 1x resolution... so nothing fancy there either. I'd need to be more careful if I was printing from the images, but because I OCR and reformat it works great. I need to straighten the camera a little, you can see the keystoning, but since it worked for what I wanted I just left it. I have to take the camera on and off as I use it for other things, so couldn't see the point in fine-tuning!
Cheers,
Anthony

I used a small, round bubble level to quickly get the camera parallel to the platen. See the second picture here:

from my original design when I also used the bike break and a point and shoot. First put the bubble on the platen and see where the bubble settles to as the table may not be level, and then put it on the camera and match the camera's tilt to it.
