Wanna work for Google?

Rob here, your friendly forum co-founder and maintainer, and guy with the banhammer. I know there are a lot of you here that played with or developed software or hardware for the scanner. You have a great skill. How would you like to put that skill to use at Google? It's an awesome place to work . I...

Re: Some (crappy) videos of Google's linear book scanner

It has been a while. Aside from approving new members, I haven't been around much. My new job at Google keeps me busy. No, I don't work for Google Books!

Some (crappy) videos of Google's linear book scanner

I shot some crappy video of Google's prototype linear book scanner. You get to see a technology that's just getting started! Did I mention the videos were crappy?

Re: DIY Book Scanner Kits Now Available!

You unbolt the top part and turn it upside down. Then the handle doesn't serve any purpose. Just press the book down on the glass, and you trigger the cameras as usual.

Re: Bimbo111's Hackerspace build

For the screws, we all use the same kind of screw you have -- with a tapering head. With a countersink tool, these work well, even in the thinnest piece of wood since you can drill with the countersink bit as gently as you want. It's a little hard to tell from the picture, but I *think* they might b...

Re: DIY Book Scanner Kits Now Available!

@mellow-yellow: I'm wondering if different cameras have different focal length/angles of view that cause this. My camera (Canon Powershot SD1100 IS) on the hackspace scanner doesn't show a reflection of the LED, and we know the geometry of the scanner is the same. There's a good picture of what I me...
