Re: Proposed 100% Linux Workflow: Capture-Process-OCR

Just a quick update: a "proof of concept" version of the scanner/software has now been implemented, and another Tulane project is spending the summer using the system and providing feedback as they go. So far it's been very helpful, from noting obvious stuff that just hadn't occurred to me (like han...

Re: The New "Standard Scanner"

coupla quick notes/clarifications- 1. note that the column bolts should be at an angle rather than next to each other. 2. if you want to drill straight but don't have the money or space for a press, a doweling jig is a really nice tool to have around and very easy to use. (As a side note, dowels as ...

Re: Proposed 100% Linux Workflow: Capture-Process-OCR

Thanks all for the support- I feel pretty lucky that this actually gets to be my job (at least, my current assignment). On that note, some job complications have slowed progress momentarily, but I did just find some nice reusable code for solving an annoying issue where the cameras randomly get assi...

Re: Representing the DIY book scanner community in NYC

I don't know what US law has as far as determining responsibility for photocopying. It comes down to indirect infringement, which is case law, not part of 17 USC. - It's contributory infringement if the entity controlling the copier induces/ causes/ contributes to the infringement. Eg, a sign up ov...

Re: Dropping out.

getting his PhD was like being an SS agent... you've got to show that bitch whose boss. It's actually not anything like that; and the comparison is profoundly offensive. My grandmother was forced to flee to this country when the Vichy took power in France- much like my grandfather's family came her...

Re: Proposed 100% Linux Workflow: Capture-Process-OCR

Thanks for the feedback. Haven't messed w/ CHDK yet, but will get there eventually. Think I've figured out how to control zoom, and plan to put index marks on the platen and camera mounts- so rather than messing with trial and error, the software can just ask, "what size is your book?" and then say,...

Re: Tape Collection

Anyways I have a big satellite dish in my back yard... So I wanted to a line the inside of the dish with aluminum foil tape and buff the hell out of it. I decided that this would be counter productive though because the tape would cost more than what I would make from the power. ...not if you add a...

Re: University of Tokyo "page flip" scanner video

My understanding is Decapod is the low-cost, DIY equivlent of this... obviously it's different approach, but they're looking to interpolate data from multiple shots of the same page (in their case, one shot each from two cameras rather than 500fps from one). I wonder whether the Tokyo system actuall...

Re: 4th Generation Scanner -- The DIY Book Scanner "Best Of"

I'm pretty happy with the picture frames and it definitely made assembly easy, but for the larger platen I'll be using plexiglass so that I can bevel the edges to better clear tight margins. Going to experiment with poster frames, but will likely end up making my own. One of the things I'm happiest ...

University of Tokyo "page flip" scanner video

Sure many of you have read about this technology, which uses a high speed camera and IR to resolve page distortion on the fly, so a book can be flipped and processed in minutes. Video's pretty rad.
