This was just too funny, the author build a lego robot that would push the “next page” button on the kindle, then hit a key on a laptop to take a picture of it, and then repeat. This way you could get past the DRM on the book built into the kindle and have a copy (or print it out).
Now using legos is a bit pricy, but I am sure using a TI or arduino could do the same job. Its an interesting workaround for DRM.
