Simple "looking" one camera book scanner

Built a scanner? Started to build a scanner? Record your progress here. Doesn't need to be a whole scanner - triggers and other parts are fine. Commercial scanners are fine too.

close the Plexiglas lid, but only at random times, otherwise the top page twists, I think
most of the problems I have encountered can be fixed

I may have to make an air vent, LOL and improve the base some more, well its progress ;)



Interesting. The fabric might be creating a static charge too, adding to the problem....requires some thought. A heavy book is less prone to behave like this, and I do remember my magazines and smaller paperbacks on the dual rigs did move a lot, and that was a hard base. A little suction is kind of nice, as it aids in page-turning, but your books are floating in the black abyss...

A merchant on ebay just replied to my inquire about their charcoal-colored convoluted foam:

They're sending a sample to me. Although it's not memory-composition, convoluted & black is something that may be more important at the moment: http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... 3681wt_967

I got looking at "copy stands" its basically what I have made, LOL , and found part of one for sale
that looks like a sheet of glass that presses on two pieces of foam parted in the middle for
a book spine,

Here is the link

I also put down some Duck brand Easy Liner to help hold the book / magazine down,
I still have to open the Plexiglas slowly, but its working better now

Looks awesome, will1384. Excellent work.

...And I have to admit I thought the foam was a fresh concept. Looks like it's been attempted in commercial production as well. I'm going to recommend a fellow forum member look at this unit as a consideration; thanks for posting on it.

Can you get a shot of your whole rig, so I can throw it up on the blog?

Yea, I guess I needed to take a good image of the book scanner , 8-) I took it outside and
snapped a few shots, then removed the background

I will do one later when I add a camera and maybe lamps

Pretty much. Sony used to be primo stuff. Far too many digital cameras (including my Olympus) have had sensor failure. Guess who made the sensors? Yep, Sony. Many of the 'famous' brands are now a signal to me of crap. RCA is one really bad one, GE and Philips are dangerous and of course Singer and several others just exist as rent-a-brands now. A lot of US corporations were asset stripped and all that was left was the name. That's why you see it used on products with no relation to the original company.

Apropos of single camera scanners, has anyone tried a "flip over" camera? You take one page then flip the camera 90 degrees and take the other page. Then turn the page of the book and repeat.

Has this been tried?

It's been suggested a few times, I know I looked into it before I built the first one. Antoha-SPB built the inverse design.

That's a good idea. I'm going to think on that. I have books that are 15" x 22" and have annoying 'perfect' binding and cheap paper.

And there are paperbacks that libraries have hard bound. Very hard to get into the spine on those!

Ugh, I know! Many of the military books I'm interested in were bound that way, making scanning with even 1/8" thick glass platen borderline...
