Hi! I ordered a beta kit as soon as I heard about it, and I just finished assembling it. This is my third scanner kit, and I documented the build at the DIY Book Scanner forums: http://www.diybookscanner.org/forum/viewtopic.php?f=14&t=3091#p1837417

Haven't actually used the cameras yet, but hopefully the construction photos will help others assemble theirs.

Thanks so much for the post -- those photos and narrative are SUPER helpful.

Yes, we are in conversation with our manufacturer about the rubber strips / glue issue and the plexiglass-too-wide issue. Those problems were not present in the prototype we gave them, nor in the demo model they first built for us... It's quite annoying to have these bugs show up in the production version.

Can you say by appx how much the plexi was too wide? Knowing the range of the problem will help a bit. (I'll ask this over in the DIY Scanner forum too, in case that's more convenient.)

One of the pieces looks to be 2mm too wide, the other looks to be 1mm too wide.

I posted some detailed photos in the DIY forum thread.

I've now updated that thread with some photos of test charts, taken using a Nokia Lumia 1020 phone.

I won't be scanning a book until I build a lighting stand and blackout tent for it, to eliminate most of the glare and reflections.

Replied in the thread over at DIY Book Scanner. Thanks again for the detailed feedback, Vitorio!
