Spreads[0] is probably what you are referring to. Some backstory:

I saw the diybookscanner community - which at that point mostly had Daniel Reetz [1] as its active contributor- struggle with mechanical contraptions for triggering cameras and very little software experience. I built a simple proof of concept to reliably trigger cheap consumer cameras using software. I built it on CHDK[2], the Canon Hack Development Kit, alternative firmware for cheap consumer cameras. The proof of concept worked.

I then had a fairly large number of book scanner kits built and shipped mostly around the EU [3]. More of a work of love than a business really, even if it was formally under an llc umbrella. Johannes initially was just a customer. He wanted to build a better software solution, and within the spirit of the project did so as free software. I tried to support him at this as well as I could, setting up build infrastructure, trying to reel in more people, getting him some cameras to test, get the amazing CHDK people to port to new camera models, ...

Then real life intervened indeed.

Johannes, if you read this, I'm still grateful for the experience of having worked with a great developer like you!

[EDIT] And of course, I should also mention Dan Reetz' incredibly inspiring work bootstrapping an incredible open hardware project! Hats off!

Hi Mark! We had electronic and USB triggering working with SDM and CHDK before you joined. But no image transfer or control of settings by USB. We deliberately pursued mechanical triggering for places where a computer and crazy firmware wasn't an option. I donated quite a few scanners to projects and people who simply couldn't use that stuff at the digitization site.

Johannes (spreads) was one of the most inspiring people I've ever worked with, so thankful for the energy and intellect he brought to the project- and the software he built. I donated a pair of DSLRs to him as a thank-you. Last I heard he was still working in a related space, but at a higher level.

Personally, I left the project to join Apple (they refused to let me continue any work on the open- source project while I was employed there), and gave Jonathon (tenrec) control. He redesigned the scanner again and sold kits as well as produced a Raspberry Pi based controller with nice software. Seems he has closed the store.

Hey Mark, hey Daniel, Johannes here, thanks for the praise, you're making me blush :D. The inspiration was mutual, I remember the time working on spreads and with you guys very fondly, learned a lot from it.

I'm still active in the "digitizing books" sector, albeit now officially employed at a library and more concerned with what we can do with the books after they're scanned :-)

I somehow thought that was illegal for residents of California, and IMHO should be illegal nationwide on general "not indentured servitude" grounds. Then again, I guess who wants to go up against Apple's legal team to find out

Hello Dan! Nice to see you here!

Rereading my previous comment, I realise that part of it could be misinterpreted. The diybookscanner project was wonderful to be part of, to contribute to.

One thing I realise was particularly impressive about diybookscanner.org was how much time you spent making it an environment friendly to broad experimentation and tinkering. Exploring broadly was absolutely necessary for a project like this. Mechanical triggering, the SDM experiments I had forgotten about, lighting, glass experiments, and more.

You sowed some powerful seeds. Your effort nursed diybookscanner.org into something that still speaks to the imagination of so many people. I feel privileged to have been part of that, and I'm more than happy to give you full credit.

Actually, it was a project called Paper Upgrade. Here is an old archive link:

http://web.archive.org/web/20140101000000*/http://www.paperu...

I don't know if you can find the code through there, but I'm pretty sure he had made it free. I think spreads is a bit newer.

Edit: Found some more info. It did indeed use Scantailor in the backend. His SW was more of a Web based frontend to all the parts. You can see a video demo of it here:

Start at about 4:40.

Paper Upgrade was an awesome project and the author changed my life. I met my future wife on the plane while flying to visit him and donate a book scanner.

BeetleB4y ago

Wow. He spoke highly of you when I met him. My guess is you had not yet married, though - it was shortly after your visit - perhaps a month or two.

And yes, Paper Upgrade was awesome (especially if he did all the work on it). I was sad to hear he had shut it down.

Oh, and I'll make a note to myself never to work for Apple ;-)
