My Bookscanner works!

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.

Wow, that's an amazing build! I saw an automatic scanner which used the same technique (but it had two flatbed scanner sensors attached to a page-sucking arm), but it looked a bit scary.

I will have to do a blog post about this when you post your talk... looking forward to your next update! Great work!

wow, very nice! 8-) I don't get where the camera will be positioned though.

The Box has holes milled in it for mounting the Cameras. The lens of the Camera fits exactly through the whole and the flat body of the Camera is sucked against the Box, so that the Buttons are usable from the Outside, but the Camera looks inside the Box.

Or perhaps a small hand vacuum (something like a dustbuster) wouldn't be so noisy, but would generate enough suction.

...so...I gave up.

I thought I couldnt control how many pages are sucked up at once. I got demotivated. I had the idea of using a buckling-motion to remove the other pages except one, but that was just a hack. I didnt wanted to rely on a "hack" for such a project, where this hack is absolutly in the critical path. Then I stopped investing time in this project.

About a year ago I threw the prototype box away. Wrong geometry.

But..yesterday evening..wohoo...I am so happy! I found what others did! - First the user jck57 used the idea of the suctionbox, but he also had problems with several pages being sucked on at once. He has his buildthread here: http://www.diybookscanner.org/forum/vie ... 064#p10064 and he even credits me. Wow! Thanks a lot!

And then I found moose, who build this: http://www.diybookscanner.org/forum/vie ... 541#p18541 and who also credits jck57 and me. Wow! just wow!

I would like to sincerely thank jck57 and moose for following the path that I started through to the end. I feel very honoured, now I know that I was on the right path, but gave up too early. I My machine would've never turned out so shiny and refined like the device from moose - so it was a good thing that he finished it, not me.

Now I am really tempted to build a machine from the Plans that moose published. Because I wanted a functioning page-turning bookscanner all along, and because I think I should honor moose through building exactly his machine.

I am very happy to be part of this community, and to see seeds that I planted years ago suddenly flourish at the other end of the world is just wonderful!

I would love to read about it if you documented your process as you get moose's scanner working. In the long term, it would be great to move from working prototypes to a 'standard' build or even a kit. When I have shown my (non-automatic) scanner to people, invariably the first thing they ask is if it can turn the pages automatically. :)

I should've followed up on this. Better late then never.

Eye-Fi sucks hard! There are ways through hacky scripts to download pictures on a linux machine. But these ways are still missing the option to delete pictures from the sd-card. also the windows-client sucks hard and it is a pain to configure the cards, because they only work in a special sd-card-reader provided by them. that special sd-card-reader works only on some linux machines. argh...never again.

I have two eye-fi-cards...if anyone wants them, i'll happily sell them!

If one wants to go that way, then I would suggest using Transcend Wifi SD-Cards. They run a busybox-linux on it and they are so weakly protected, that you can just follow some online tutorials to get a full terminal, and root through telnet. From there on the path to using scp or rsync or whatever to download the images is a short path.

A broader perspective over the c-lib (library) in c-base with the Bookscanner on the Left

The Bookscanner in c-base
Some Updates on my Bookscanner:

We rebuild our library, mounted a lot more shelves and sorted all the Books in. During this, we also found a permanent space for the Bookscanner. I have pictures attached.

People from c-base finally got chdkptp and a new chdk-version on the cameras running. In April 2014 the Bookscanner got a dedicated Computer, an i5 with 8GB RAM. After a lot of hassle with Ubuntu, we decided for a Fedora with Gnome.

Also we finally got the expensive brand power supply units for the canon cameras, because all 17 attempts at building our own battery dummy failed. We tried everything, from cardboard, to wood, 3d printed, cut from plastics, lasercut...nothing worked reliably. then we bought the expensive option.

This means that the cameras finally can stay mounted permanently and be ready to use for every member of c-base.

The counterweight got reworked - the cogwheels got replaced for aluminium turned smooth wheels. the bearings are now inside the wheel and not where the shaft is mounted. makes for a much smoother movements. also quieter.

We also attached a Barcode Scanner to the System and someone started developing an opensource library management system. https://github.com/ri0t/johannes
maybe in the future that library management system could be hooked up to spreads as well.

Quite nice are Toshiba FlashAir but only W03 (third generation).
