Re: Brainstorming about portable book scanners.

The "different sized pages" thing is probably a problem that's unique to my initial setup -- no fixed-to-a-column platen, and no sliding book cradle. My cameras were fixed, and my book cradle was fixed, so the first page of a 3-inch-thick book was three inches closer to the camera than the last page...

Re: Brainstorming about portable book scanners.

Also (not really relevant on the Portable Book Scanners thread, but here we are), having the camera affixed to the platen simplifies my shooting. I'm going with manual focus and manual exposure, so there won't be any "2-lines of off-center text befuddles the autofocus" issues. Having the page at a c...

Re: Brainstorming about portable book scanners.

I'm mounting the cameras to the platen so that they're always the same distance from the page they're shooting, meaning the page is always in the same place and the same size in the picture. This simplifies my post-processing; I can just say "clip (20, 20) to (1280, 3170)" on each picture, and not h...

Re: spare parts?

I can probably send drawer slides, if the postage isn't more than the slides are worth. I also bought a handle I ended up not using, and lots of nuts, bolts, and angles. Also some pieces from a picture frame which I'd intended to use for the glass platen. They may be large enough for someone else, b...

Re: Electronics/Handle packages for sale.

Hey, can that laser handle a 12" vinyl LP? I'm thinking that as part of my increasingly minimalist lifestyle, maybe I can convert some of those to sculptures, since I really no longer use them for playing music.

Re: Electronics/Handle packages for sale.

I don't need a plate. If I decide it needs to be stuck someplace, I'll figure out where and how to stick it.

Re: Help verify my design

Sixtysix, while I'm in the process of building a second-generation scanner on which the cameras will be attached to the platen, the first scanner I built (and the one I'm still using) has cameras on tripods. It also has a platen which is not attached to anything (I just lay it in the book), and a v-...

Re: Help verify my design

Kentsin, it should work. I wonder how you're attaching the cameras to the ladder. If it's really a standard ladder, the steps will be horizontal, and if the camera is pointing horizontal, it won't be photographing the book. But if you have already worked that out, and the cameras are aimed perpendic...

Re: Brainstorming about portable book scanners.

I think that 2-way panel connector looks like just the thing. Here's another one from a place in Cleveland, technologylk.com: PanelConnector.jpeg For every three or four photos taken gently slide the cradle to the left. Some libraries may even provide a reading lamp inside a closed reading desk. I t...
