DIY Book Scanner

143MP scanner camera: http://petapixel.com/2014/12/29/medium-format-camera-made-using-parts-epson-scanner/ Looks like the project's been going on for a few years now, not sure why it's just hitting the blogs today. In this particular Flickr photo, though, he also mentions what sounds like a mechanic...

According to the manual, this also works if one of the phones is serving as its own access point, with the second phone (and your controlling device) connecting to it, which means a multi-phone + controller setup could be pretty self-contained. Bluetooth remote control looks to be meant for hardwar...

I've been investigating the Nikon 1 J3, which is a consumer-grade mirrorless DSLR camera that costs ~$400 with a kit lens. This camera has no mirror and also has an electronic shutter, which makes it quite robust. I've shot more than a million shots(!) on a Nikon J3 and the camera is still operatin...

I've taken some JPEG photos of test charts using the 1020 and posted them in this thread: http://www.diybookscanner.org/forum/viewtopic.php?f=14&t=3091&p=18438#p18438 . The tl;dr is ~430-470dpi in the Book Liberator scanner, which is better than the ~350dpi I get out of the A2200s in the Hackerspace...

Turns out there was latent adhesive gunk on either the acrylic or the cradle, because when I went to dust off the platen, there was residue on one of the cradle/acrylic sides. Very annoying, and it's not coming off great. Anyway. I moved the table and the Book Liberator directly underneath that over...

How do you know what your cameras are doing, when they're on the sides of the machine and you're in front of it? How do you know when CHDK messes up and gets your camera stuck in the menus? Haven't seen anyone do this, so while I was swapping out the Raspberry Pi model B for a model B+ (getting rid ...

Can you say by appx how much the plexi panes were too wide? Knowing the range of the problem will help as we discuss this with our manufacturer. It's a little hard to say, because there's a bit of give because the wood doesn't screw together precisely, even with the pre-cut holes: mis01.jpg One of ...

Okay, so, first things first, I experienced both of the "known issues" described on their site . First one: The rubber strips that help the base grip the table surface aren't glued strongly enough to the underside of the base. We found this in testing and have already talked to our manufacturer abou...

I didn't find any serious attempts here in the forums, but maybe I didn't look hard enough. Out of the box, flatbed scanners aren't really well-suited for non-destructive scanning of anything other than sheets of paper. One problem flatbed scanners have is there's no way to get right into the spine ...

I did plug the camera usb into a 5v power source. Then with the camera running, I plugged in the 5v source the camera reacted, but did not take a picture in either the one or two push position. You have to give it power, and then remove it. It focuses when it senses power (like pushing the shutter ...
