Re: 'Pyramid'-shaped scanners (Tamtus, Atiger)

rather than just turning the pages you have to pick up the book every time. plus you would have to index the book every time as well. or am i missing something? With the usual scanners, you have to lift the platen (the V-shaped glass that flattens the pages), turn the page and put the platen back d...

Re: 'Pyramid'-shaped scanners (Tamtus, Atiger)

This is really interesting. I liked the compact, self-contained-ness of the Bookliberator design, but understand better now how it could be problematic with thick books with wide spines. Do inverted models like this still have problems with wide spines? Would an inverted version of the Bookliberator...

Re: Microsoft Kinect: infrared depth maps for dewarping?

The minimum focal distance of the Kinect is around half a meter or so, and it occurred to me that perhaps I could use e.g. reading glasses to correct that, but actually trying it resulted in no depth image at all. From some discussion in #openkinect: (08:59:33 PM) marcan: not going to work (08:59:44...

Correct!

Re: Sola Technical's $70 acrylic scanning platform on Ponoko

That sounds a lot less convenient than I was expecting. Glad to have this review, since I was looking at that kit myself. In software development, there's an idea of "build one to throw away," that you can't know all the things you need to know about building a system until you've built it, so buil...

Re: Sola Technical's $70 acrylic scanning platform on Ponoko

Actually, as I wrote that, it occurred to me that perhaps I could lower the tower below the bottom of the base, by using the top hole and lowering it through to the bottom of the slots in the base assembly, like this: offsetplatform.jpg That gives you a couple extra inches of vertical room, but it's...

Re: Sola Technical's $70 acrylic scanning platform on Ponoko

It's definitely hard to see considering it's all transparent! Here's the "final assembly" illustration from the instructions: scannerassembly.png The "platform assembly" has two sets of three holes on the vertical stands, where the thumbscrews and wingnuts go, so you can either have it go right up a...

Re: Sola Technical's $70 acrylic scanning platform on Ponoko

Along with a bag of thumbscrews and washers and wingnuts, and a flatpack box full of laser-cut acrylic, there's half a dozen pages of illustrations for assembly instructions. Here's how Sola recommends lighting the platform and positioning the camera: scannersetup.png It includes the note, "scan in ...

Sola Technical's $70 acrylic scanning platform on Ponoko

So, quoting my hello post, I've finally assembled this scanner. (It's still setting, so I won't be trying it until later.) Hi, all, I'm here because there's a bunch of out-of-copyright design books that I'd like to liberate. :) I didn't see anyone here talking about it, so I ordered this book scanni...
