The DIY Book Scanner
azoblue writes "Daniel Reetz did not want to lug around heavy textbooks, so he built a book scanner to create digital copies. '... over three days, and for about $300, he lashed together two lights, two Canon Powershot A590 cameras, a few pieces of acrylic and some chunks of wood to create a book scanner that's fast enough to scan a 400-page book in about 20 minutes (PDF). To use it, he simply loads in a book and presses a button, then turns the page and presses the button again. Each press of the button captures two pages, and when he's done, software on Reetz's computer converts the book into a PDF file. The Reetz DIY book scanner isn't automated — you still need to stand by it to turn the pages. But it's fast and inexpensive.'"
This would be a good activity for the winter months when farming isn't possible.
Here comes the Publisher's Copyright Enforcement Gundams to give you "What For!".
Imagine that, thinking you could actually DO Something like that with your very own property.
What cheek!

Except for the lack of an automatic page-turner, Daniel's device is the same as one you can buy commercially for about $20,000 (http://www.treventus.com/bookscanner_pageturner.html).
He was wise to decide on manual page-turning.
I'm a Programmer. That's one level above Software Engineer and one level below Engineer.
I do this for my law school textbooks (unless you're a book publisher, in which case I am joking and would never break the law).
I was excited when I read this because it is a pain in the ass to turn the pages in a 1000 page Constitutional Law textbook. Thus, you can imagine my disappointment when I read that his machine doesn't automate this.
Most universities have at least one library which has a Ricoh scanner that does exactly what his does, i.e. it writes out a PDF onto your USB stick. I don't know where he's a graduate student, but I bet if he looked in his library he could have saved himself $300.
How soon before the manufacturer of the $20,000 commercial version files a lawsuit against him? That would be extraordinarily sad because the American system of patent/copyright only serves to stifle independent innovation like this.
It may work well enough for basic textbooks, but the problem is that (for high-quality scans) you can't ever get the same image quality from a $800 camera that you can from a $80 scanner. At 1200 DPI, a scanner is equivalent to a ~384 MP camera. Even scanning at "only" 300 DPI is ~90 MP, a far bigger image than any consumer-grade camera can provide.
The cameras he used were only five megapixels.
Might work for looking at the pages on your iPhone. Not gonna look very readable on your laptop screen, and forget about reading the book's footnotes.....

What a coincidece! I too have a book scanner that scans books, and requires a human operator to attend to turning the pages.
It's called a scanner.

Same thing, much cheaper (I built mine for ~150 USD.)

You must not have ever gone to college. A textbook for $15? Get real.
He keeps talking about how expensive the books are. Clearly he is just using this to scan other people's books to avoid paying.
Still a pretty cool build though :P
This is a market that relies on outrageous reproduction prices just like cd's used to. They are equally doomed. I know a LOT of college students who no longer buy books ... they rent them for free by buying them, shooting them, and returning them. It may take a couple of hours to do manually without a device like this, but $80 per hour is pretty good wages for a college student.

I do it in 5 steps, and you get rid of the book when you’re done since you don’t need to store it. After you get done putting 200 hours into your creation, you’ll have spent thousands of dollars worth of your time. I solved this problem much more quickly years ago:
1. Buy a good sheet-fed and high-speed scanner. I have a Panasonic KV-S2026 color.
2. Get a decent jigsaw from Home Depot. Use metal cutting blades (24 teeth/inch or better)
3. Saw the spines off the book and for God’s sake use some C-clamps on each end of the book. Preferably sandwich them between two flat boards.
4. Remove and feed sheets through the scanner to OmniPage and text recognize the pages.
5. Save as PDF.
6. Repeat. You now have searchable digital books!
Ironically, all these books that he and others are trying to scan into a digital format where created in a digital format from the start, sitting on a publisher's computer somewhere.
Thanks copyright laws! Thank you very little.
One semester's worth of books in college today runs around $1000. With this device you can return the books after you've scanned them. If you rip out the binding, most bookstores are going to frown on returns.
So this device saves about $700 the first semester, and $1000/semester after that.

I'm amazed at how good OCR has gotten. I did the same thing without building anything: just connected my Canon PowerShot A540 to a tripod, lay the tripod on a coffee table, put the book on the floor, and started snapping away. Fed the JPGs to ABBYY FineReader 10, and it spit out plain text that was *at least* 97-98% accurate on every page. I did not use any special lights, do not know anything about photography, and frankly thought I'd have to buy all sorts of special equipment. The only other thing I added for convenience sake was Dirk's CanoRemote so that I would not move the camera (however imperceptibly) every time I pressed the shutter.
The scanner was described 3 months ago in a question to Ask Slashdot:

See also the BookLiberator, a somewhat more compact cube-in-cradle design, that's also easy to build. Although soon you won't have to build your own: we're prototyping a manufacturable, flat-packed kit to sell from our online store; see questioncopyright.org/bookliberator for more about the project. It should be ready next year.
None of which is to detract from Reetz's accomplishment, of course. This renaissance in personal book scanners is going to make it easier for all of them, in the long run, especially as we can share the same open source software among all the scanners.

I feel fantastic, and I'm still alive.
A while back I got a Fujitsu ScanSnap S510. Now when I want to scan a book, I just saw the spine off (table saw, band saw or even a steel ruler and X-acto knife will do the trick). Take the loose sheets, about 40 at a time, and put them into the ScanSnap. The ScanSnap comes with Acrobat Pro and does a fine job of making a searchable PDF file of the book. The paper? Into the recycle bin. I've cleared off several feet of shelf space.
