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.'"
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!

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.....

If so, wouldn't it be easier to just rip out the binding and put in the pages? The $15 cost of buying another copy is less than all that boring, repetitive manual labor.
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
Really? Scanning takes a fair number of seconds, then you need to lift the book in order to turn the page, set it down correctly, and start the next scan. Compare with: push button, turn page, push button. Limited pretty much by how fast you turn the page.
True confidence comes not from realising you are as good as your peers, but that your peers are as bad as you are.
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.

The automatic page turner costs an additional 19700 / 833 hours = 23.64 per hour. Hire a high school student for 8.

Even thousands of dollars worth of your time can be recouped easily over 4-5 years of college book costs. And rarely will a college student find a job that pays better than scanning their own books to save book costs.

..and enterprising kid could buy the popular undergrad books, cut them up, use a professional autofeed / OCR scanner (pirate the software) and make a tidy sum selling USB keys for ~500 year old knowledge that should have been opened and standardized in form a LONG time ago. It's fundamentally _wrong_ that kids need to pay $1000's for undergraduate books when the fundamentals are hundreds of years old.
Fuck the SOBs. You could make the argument that undergrads shouldn't even need books, if the Profs were actually as good as most of them think they are.
I was reading about OCR accuracy in my Game Developer magazine just last night, and they were lamenting that 98% accuracy really wasn't good enough for them. I know that the difference between personal and professional use is rather wide, but they printed a few sentences with 98% accuracy and I will admit, it was distracting. Of course, if they hadn't mentioned, would I have noticed?

For-fucking-ever.
I feel fantastic, and I'm still alive.
