Re: I have a page turner idea

when the guys at 3M designed the adhesive for Post-Its they were careful to make it strong enough to not fall out, but weak enough to not damage the paper. If you can get ahold of post-its by the roll (seems doable) or if you can find an alternate source of that kind of adhesive, you'll be in like F...

Re: A task for volunteers: handling out of memory situations

spam just says your email address has gotten into the wrong hands, bug reports go right to your ego, saying "you're not as perfect as you thought yourself." of course they'll be bigger pain. what software needs is another function that generates "attaboy" reports when the software does something par...

Re: Suggest improvements to the site here.

At some point in the near future I will start a thread where people can post samples for a sort of "diybookscanner standard image set". Perhaps we can make a sample book that the whole community can scan as a quality test. i think this is a critical need. If we all had access to the same edition of...

Re: Input on the best way to build a portable scanner

if you look back a ways, you'll see where someone bisected a cardboard box along the diagonal of two opposite faces, and folded them back, creating a book cradle of the two halves. this is a pretty fold-flat, if ghetto, design. at least for the cradle. one might travel to parts unknown with the inte...

Re: Simple "looking" one camera book scanner

the two front legs of the tripod are set shorter than the back leg, and the two front legs sit to the sides and just a bit above the bottom of the book. The tripod is not especially stable in this configuration -- my camera's heavier than a pocket cam, and if I bump it forward, it could fall over. ...

Re: Daniel's 5th Generation DIY Book Scanner

as you explain it, it makes perfect sense. with an infinitely distant point source, all rays of illumination are parallel. what had me confused is the lore that a north-facing window is what artistes find most desirable. what i failed to realize is that the illumination in that case is largely atmos...

Re: Daniel's 5th Generation DIY Book Scanner

lambertian? you obviously know what you're talking about and i'm talking out of my hat where glare is concerned. maybe we'll just use the 8' cube as a sauna.

Re: A task for volunteers: handling out of memory situations

Tulon, I just got scantailor to compile on my MacBook. And I just installed 64-bit Win7 on a bootcamp partition. It remains to install Visual Studio 2010 (or 2008, i'm not sure which i want) on that partition. Then I'll be able to compile scantailor for you. Or does your windoze port use another com...

Re: Daniel's 5th Generation DIY Book Scanner

i figure the bed sheets would serve as a diffuser and mitigate glare. Imagine a 8' x 8' x 8' cube made of PVC pipe with bed sheets pinned to the frame sitting in direct sunlight.

recruit operators from the nearest sauna.

Re: Daniel's 5th Generation DIY Book Scanner

is there a reason natural lighting cannot be used? Make a tent of bed sheets and PVC pipe then operate the scanner in direct sunlight. Or something.
