Re: 16 MP?

No wiki?

Forget links not working, when I go to http://www.diybookscanner.org/wiki/ I get this:

Not Found

The requested URL /wiki/ was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Re: Methods To Sense The 3D Surface/Structure Of A Book

I had a thought the other day: Why lasers? What if you had a nice physically stable glass slide with colored lines on it and just projected it on the book with a slide projector? It would be easy to make a slide with a grid for picking up finer details of the page geometry rather than just having a ...

New Polaroid camera looks interesting

http://money.cnn.com/2012/01/16/technology/polaroid_android/ Maybe no more microcode hacking needed to get control, just android programming experience? (Depending on how much control polaroid actually gives you over the camera bit). Naturally, there is also the question of price, which isn't mentio...

Re: Getting started to build a Book Scanner

This post:

http://diybookscanner.org/forum/viewtopic.php?f=1&t=910

has a bunch of info on camera triggering techniques.

Another thing to consider is that (not too long ago anyway) reconditioned A480s were available from the canon store, and the A480 is compatible with CHDK.

Re: My linux automation code is making progress

I haven't updated my status for a bit, but I have been plugging away (when not filling out my tax forms, etc) and I just loaded a new version of the code.

Re: Wiring needed to hook up cameras with gphoto2?

If you are going to be using the CHDK or SDM firmware and want the USB line to be able to trigger taking a photo, then you need a switch of some kind that can toggle the USB power on and off. If the cameras can be fully controlled directly by gphoto2 and you are going to want a 100% USB connection, ...

Re: Introducing djvubind for djvu file creation

I am not familiar with any VM environment other than VMWare - but is there any reason not to use it? Well, the only reason would be valid for every virtual environment: If the user already has virtual machines based on environment X, he wouldn't be able to use environment Y, but since that argument...

Re: Introducing djvubind for djvu file creation

Building a LiveCD is pretty simple with the tools available in fedora. Lots of folks have special "spins" they produce each release customized towards one thing or another. I have no idea if any other distros have similar (or the same) tools. Here's one link to info on using the fedora tools: http:/...
