Ion Audio is coming out (“Soon!”) with a gadget to let you photograph your books quickly and easily. Take a look at it here.
I’ve been thinking about building something like that myself for most of last year. (See this video for some ideas about how you’d do it yourself.) But the DIY project that guy outlines involves finding two cameras that can run CHDK, and a computer that can run some kind of interleaving software, etc., etc. The appeal of a turnkey solution is pretty significant.
(The pricing isn’t set yet, but if they can hold it to something like the estimated $150, that would be another draw. The DIY project would cost that much, plus a lot of time.)
