Re: Most effective ways to reduce glare and unwanted reflect

The only thing I'm confused about is your mention of white balancing. I'm a total photo-editing noob, so I'd appreciate additional clarification. Also, are there any specific settings you use on your camera to get better results? I basically just turned off the flash, zoomed in and let the camera d...

Re: Most effective ways to reduce glare and unwanted reflect

I spent several hours studying the glare on my scanner, same build and cameras, and my results are: Turn the lights off. My scanner is under a scaffolding, so the rest of the area's lights don't affect it, but the lights directly by it all need to be turned off. The LED lamp should be the only light...

Re: Raspberry Pi + LCD + footswitch

This seems like a great base to build on for my scanner. Thanks for documenting your work! I will probably swap the RPi LCD for a proper HDMI LCD instead, as those are in no short supply at a hackerspace, and it opens up the option for a preview window, which will be nice for making sure the book is...

The scanner is tested and documented and open for use, now (for members, and for the public with supervision).

Re: Austin Hackerspace kit build

So that's basically your usage manual there. I'll be writing a software processing manual, as well as figuring out some sort of inexpensive computer solution, at some point, because this whole thing is not foolproof without AC and PTP-based CHDK triggers, and then I don't even know what to do about ...

Re: Austin Hackerspace kit build

How to use the Austin Hackerspace book scanner First, some caveats: The book scanner is calibrated for the exact location it is currently sitting in. If it needs to be moved, I will have to come in and recalibrate it. It should not be moved arbitrarily or without notice. The book scanner is a littl...

Re: Austin Hackerspace kit build

Blergh. I went into the Hackerspace to set up triggering with CHDK, and hopefully do some test scans. Triggering I went with two generic 5V USB AC adapters plugged into a power strip. Turn on USB Remote in CHDK, toggle the power strip on and off, and both cameras fire. Great! Unfortunately, power-ba...

Notes on KIC BookEye 4 scanner design and use

My university's main library recently installed two KIC Bookeye 4 scanners for public use, and I finally had the chance to try them out. They're fairly large units, taking up as much square footage as a traditional photocopier. They're also fairly expensive units: this configurator puts the base pri...
