Daniel Reetz, the founder of the DIY Book Scanner community, has recently started making videos of prototyping and shop tips. If you are tinkering with a book scanner (or any other project) in your home shop, these tips will come in handy. https://www.youtube.com/channel/UCn0gq8 ... g_8K1nfInQ

Libreflip - a new open source page-turning bookscanner

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.

Libreflip - a new open source page-turning bookscanner

Post by Aegre Reminiscens » 13 May 2018, 08:37

TL;DR: I am making an automatic page-turning open source book scanner and I create weekly videos about the project.

Sometimes I take on projects that are reaching far. This one is no exception. I wanted to share this project with all of you for a while now, and now as the project is well underway, I can do that. With the support of Wikimedia Deutschland and c-base I have created a project called Libreflip, a page turning book scanner! It is open source, because I want everybody to be able to recreate one of these machines. I tried to minimize the necessary tools as much as possible and I am creating a video series about every step of building the machine.

I believe that too much knowledge is bound to one place. Libraries are bound to opening hours and charge you to scan your books. Companies scan books but do not give you free access. By open sourcing this machine I want to enable makers and communities all over the world to create automatic book scanners. Information should be accessible for everyone and this is a important step towards it.

Current commercial book scanners, are usually cost-wise well in the 6-digits, Libreflip is in the lower 4-digits. This low price point keeps it accessible for communities, small libraries and book-rescue organisations.

Please support the project by telling others about it, on- and offline. I publish new content weekly on Youtube, which gives you regular helpful propaganda. And, Youtube still offers this rare and free feature called “subscribe” which helps you never miss new content, so please subscribe now ;-)

Credits go out to the user moose for beating me to it, thanks moose! His contributions are described in the first episode of the Youtube series.

PS: Actually, I just want to enable our future AI-Overlords to parse all of human knowledge, but please don't tell anyone.

Could you please tell more about those "USB 3.0 Industrial Cameras with 13 Megapixel each" which are included in the "just electronics" package?

I had been looking for such, but found only cameras geared towards video, not stills.

Added somewhat later:

I found it on your website: http://libreflip.org/index.php/2017/04/ ... a-problem/

Yes, exactly. I am currently using the CU130 of E-Con systems: https://www.e-consystems.com/UltraHD-USB-Camera.asp

I would be thrilled to try the DFK AFU420-L62 of The Imaging Source (https://s1-dl.theimagingsource.com/api/ ... .de_DE.pdf) in the future, because it would allow to have a scanner whith more the 600dpi, which would be pretty cool.

It would. But I would need a sponsor for buying even only one of those.

These industrial cameras are made for rather video or high frequency fotos, while for book scanning a reguar stills camera would be sufficient.

And I do not necessarily need color. Well, for the one newspaper published in exile during the Nazi rule in Germany, color might be useful, as an archival feature.

there is not much difference there any more. It all comes down to the resolution of the chip - the higher the resolution, the lower the FPS. No one really makes "Photo"-Cameras anymore, digital cameras in smartphones don't have a (hardware) shutter anway, same with these industrial modules. It's just a chip with a big load of pixels.

I could've gone with a Canon-Camera and CHDK, but when I started (November 2017), there was not a single camera on the market that was still being made or from which I could've bought like 20 or more at a time for which a CHDK-port existed, so I had to change to something else. The industrial modules are nice, and if we (as a community) decide to massdrop/bulkorder on these, the prices will go down as well.

When can I expect your project to be complete? I am does it have some sort of deadline or something? If yes, I'll order one for me for sure.
