Intro: DIY High-Speed Book Scanner from Trash and Cheap Cameras
I love books. There is some truly fantastic knowledge and information hidden out there in hard to find, rare, and not commercially viable books. I find that I ...
Step 1: Material Acquisition: Dumpster Dive in the Day With Your Camera
Let's start with getting the things you need.This book scanner employs recycled, found, and salvaged materials at every step. I think it's important to note that this is ...
Step 3: Material Acquisition: Buying Recycled Stuff.
Finally, dumpsters are far from the only place to find things. This project requires some things that you will never find in dumpsters -- like working light bulbs. ...
Cut your board into appropriately sized pieces. Because it is easier to cut 2x4's than countertop material, I simply measured my piece of countertop and sized the boards ...
Make a little template to drill pilot holes for your woodscrews. I used this piece of plastic angle, but you can use anything, even a folded piece of ...
Step 13: Bookholder: Introduction and Design Issues
Congratulations on making the base for your book scanner.One of the nastier problems in scanning books is that the "center" of the book shifts as you flip through ...
Step 14: Bookholder: Introduction and Design Issues (Continued)
There are many ways you can make the book holder. In fact, my first book holder was made entirely of cardboard, and it worked well enough to digitize ...
A hot glue gun is a good tool to have. The hotter, the better. Miter box, 14" Harbor Freight Part Number 99932.HDPE.Beg, borrow, find or steal some HDPE ...
The next part of the book holder assembly is where the book actually rests. As with the other parts of this instructable, you can (and should) substitute other ...
Cut two pieces of coroplast (wood, MDF, etc) at 11x15". 11x15"... This is one of the few hard recommendations in this instructable. I have found that this size ...
Glue the two 11x15" pieces together at a perfect 90 degree angle. I glued them together with industrial hot glue. This stuff is pure magic. Highly recommended. I ...
Step 23: Bookholder 2: Sticking Books Down With Toolbox Liner
Attach the toolbox liner material to the VST. This keeps the book from sliding when you scan it, which is critical to the operation of the device. This ...
The plastics in this part are something you should buy new. Unfortunately, I have found no good way to make a platen from recycled materials. I have made ...
Have your pieces cut at a local plastics place. Ask them, if possible, to route the edges smooth. It will make gluing the pieces much easier. If you ...
Assemble your platen as shown. Leave the plastic/paper covering on as long as possible. If you make even a small scratch on the imaging surface, that will be ...
Step 32: Lighting: Why You Should Use Halogen Bulbs
Let's talk for a minute about lighting. Now, one thing that made me laugh is that in the very description of the Epilog Laser contest, they mention using ...
Step 33: Lighting: How To Light For Cheap, Crappy Cameras
Let me start by saying that this whole system is designed to work under non-ideal conditions and to be manufactured from just about anything -- this is less ...
Why not CFLs? Fluorescent lighting is totally inappropriate for photographic devices like these. First of all, fluorescent lights flicker at 60 or 120hz. Flicker isn't their only problem, ...
Step 35: Lighting: The Solution, I Said It Already
So perhaps surprisingly, the most sensible choice was halogen lighting. On my first scanner, I bought new halogens and found that their lack of flicker, super-high output and ...
All that said, mounting your lights will depend on what you can find. I found this very neat light bar at Habitat for Humanity ReStore. It cost 1$. ...
You'll need at least one working camera to move this project along. Firmware installation is step 1. Because it is so complicated, I made a video for you ...
Step 40: Video Switch: Solder all grounds together.
Connect all grounds/shields together. The two input grounds and the output ground should be soldered together. I found the grounds by touching my multimeter to the shield of ...
The two scanners I've built so far feature two different display systems. You should strongly consider using some display system on your scanner, because plugging the cameras in ...
Get the datasheet for the voltage regulator (and other chips if you suspect them). I used Octopart.com to look up the datasheet by entering the numbers as they ...
Reassemble the device! You now have a free, recycled LCD screen for any project. I also made a little visor for mine from a scrap of black foamcore ...
The easiest display is just an old analog TV. Try to find one with composite (RCA) inputs. Since the digital switchover here in the US, I have seen ...
For the new scanner, I happened to have the remains of two Elmo Classroom Presenters. They're usually used in classrooms to project the handwriting of the professor. I ...
Left to find was an appropriate camera bracket. For the Canon Powershot A590, I discovered that 2" angle brackets are the perfect thing. They provide good support across ...
Step 54: Camera Support: Screws to Hold Your Babies in Place
Mounting the cameras is simple. I make little DIY camera finger bolts by taking a 1/4 20 bolt with a flattened head (unfortunately, I can't find the name ...
The firmware we installed earlier allows the cameras to be triggered electronically using their USB connectors. To get them to fire at the same time, you need to ...
Disassemble your flashlight. Take out the battery case. Sand the ends of it to prepare it to accept solder. Remove the batteries and solder a red wire to ...
Returning to the other side of the flashlight, assemble the threaded rod, washer, and junk as shown. The idea here is glue the rod into the center of ...
Mark your platen, drill mounting holes and mount the handle assembly to the platen. I put velcro on all this stuff and velcro'd it to the base. That ...
The previous switch designs were electronically similar, but had some shortcomings. For that reason, I'm just going to show you some pictures and discuss them a little bit ...
You got this far, the final steps are pretty easy. Paint your device. To get good output from our cameras we need to eliminate sources of glare, and ...
At the time of this writing, the best camera for this task is the Canon Powershot A590 IS. It has enough resolution, enough manual control, works with CHDK/Stereodata ...
Step 75: Final Steps: Plugging it All Together and Powering it UP
Hopefully your cameras have arrived by now. Plug your main outlet strip into the wall. Plug your TV into the outlet strip. Plug your lights into the outlet ...
Aaron Clarke wrote the software to process the output of this book scanning system. It reads in all the images, allows you to set a crop, corrects for ...
Run Page Builder by clicking on "PgBldr.exe". Watch this tutorial video to understand the interface conventions. Page Builder is highly effective software, but the efficiency is largely due ...
I love books. There is some truly fantastic knowledge and information hidden out there in hard to find, rare, and not commercially viable books. I find that I want my books with me everywhere. But that's where the problems begin. Buying, moving, storing, and preserving books means environmental costs... and when I loan a book to a friend, I no longer have access to it.
Digital books change the landscape . After suffering through scanning many of my old, rare, and government issue books, I decided to create a book scanner that anybody could make, for around $300. And that's what this instructable is all about. A greener future with more books rather than fewer books. More access to information, rather than less access to information. And maybe, years from now, a reformed publishing/distribution model (but I'm not holding my breath...).
UPDATE: We've outgrown the Instructables commenting system. There's a new place to discuss book scanner building -- please join us at DIYBOOKSCANNER.ORG -- and BTW, you don't need to register to get a PDF of these instructions. UPDATE:9/16/2011 - Instructables has kindly made the PDF download public for everyone. Thanks, Eric.
I've built two of these things now, and this instructable covers the best parts of both of them. You can build a book scanner using only hand tools plus a drill. I realized that not everyone is comfortable with using all the different hand tools you might need to make it. So I scanned a book on using hand tools that should answer all your questions. ;)
Download a sample here. Download the entire book (115mb) here. I may have to remove this if there are too many downloads. Please note that these were taken before the scanner and software were complete. Scans from the final system are much nicer.
We have written some open-source, free software to convert the images from your scanner into PDFs. It's currently in a rough alpha stage, and needs a pretty fast computer to get things done. It works on Macs and PCs. Help us improve it! This software is covered on step(78-79).
Let's start with getting the things you need.This book scanner employs recycled, found, and salvaged materials at every step. I think it's important to note that this is not only because it is the right thing to do, environmentally speaking, when prototyping and building things, but also because the major thrust of this project is to make it affordable for almost anyone. Affordability often means getting creative with what you have and what you can find.
One of the problems of building this way is that there is a strong stigma against recovering things from the trash. I'll admit that this affects even me on occasion. With that in mind, I want to show you a little dumpster diving trick that's socially acceptable. It's terribly simple. Take your camera, and hold it over the edge of any dumpster you find interesting. When you get home, see if there's anything that will help you. Later, return under cover of darkness and recover whatever it is you needed.
I spent almost a month thinking about this second book scanner and where to find stuff. During this month, I was vigilant about noting the locations of various construction dumpsters, and I also kept an eye on trashcans whenever I passed them. Whenever I saw something interesting, I made a simple decision. Should I grab it now, or simply photograph it? If it was a dumpster, I photographed it. If it was something useful, I grabbed it right away. It's good to keep a fabric shopping bag or backpack on you to transport all the stuff you will inevitably find.
<p>I have built a few fully custom PC towers, I have owned and used quite a few high-end PC laptops, ... I do understand this, because that's exactly how I feel about cameras. ... that could be borrowed from the pages of a “for dummies” book.</p><p>Recently working on http://www.mobilepundits.com/ and make it a book for mobile application development! Any guidance?</p>
