Re: Image registration via barcodes

As to the question of whether the barcode's z-separation from the actual page plane is important... I suspect a little bit, but not enough to matter. The barcode page will always be at the same z-distance from the camera, while the pages will move up and down due to the thickness of the book. And s...

Re: Image registration via barcodes

Does it matter that the barcodes are not moving with the focal plane?

Re: Beta number 2

3) I did not think of adding a "spine allocator thingy". What i was thinking of doing was going ahead and having the book rest sit in a permanent position. Is this a good idea?? Or should i really consider having that feature added to my beta??? I would say that it's a definite must. Otherwise the ...

Re: Beta Build

Yeah, I like it a lot. It's pretty fast. The fam gets a little bugged out with a camera in their face all the time though.

I'm posting this pic to show the slides between the base components.

Re: Need a shopping list ASAP to help Aboriginal Communities

I'm not sure that my build would be very good for a platen size any bigger than it is. At least not without modification... basically because of the torque generated by the weight and the distance from the sliders to the handle. Dan, what do you think would be necessary for a more complete set of do...

Re: Beta number 2

Hey, cool design! Here's a tip for epoxy... tape off the glass with blue tape leaving only 1/4" exposed on the edges. Then, apply the epoxy to the taped-off glass (and not the MDF). Lay it on thick because the MDF'll soak it up. Peel off the tape and you'll be left with a perfect 1/4" bead of epoxy....

Re: Beta Build

I'd be interested in seeing a before-and-after set of shots with the JPEGs straight out of the camera. Sure! Not the same book, but you get the idea. Unfortunately, I had to resize it due to the forum's allowable size limit. 209.jpg Basically, I sample a page from the beginning, middle and end of e...

Re: Beta Build

Not sure where to post this... here or book projects. Not sure about copyright issues either. But here's a post-processed, 4-page sample from a recently scanned book for those that are interested. Post-processing workflow consisted of Photoshop, Scantailor, FileRenamer and then a final crop in Adobe...

Re: Beta Build

I thought I had lost this pic, but I found it on a spare memory card. These are the MDF parts, post-paint. The work table is a remnant of my former life as a carpenter. It's awesome but you don't need one to cut the parts. In fact, I cut most of these in the snow, on my deck, propped up on cereal bo...
