Using my newly built DIY Book Scanner! 

Thanks Alex Sh. I actually spotted that one in the other issue of QuickTALK that I scanned. ScanTailor is one hell of a great post-processor.

Thanks! (For those in the audience, Daniel is the guy that designed the scanner shown in this video.)

Thanks!

You're welcome!

Thanks! Most users of this type of scanner actually use a USB connected foot pedal to fire the cameras.

Thanks!

Acrylic can flex slightly and may distort the image the camera sees. It's also very easily scratched as it's a LOT softer than glass. Thanks for your comments!

@@f15sim Ah yes. Makes sense. Thanks!

If you're doing a one-off and have no intention of scanning anything else, that would work. Beyond that it's not really practical.

The two Canon Elph 160 cameras were $159 each from Amazon. The 3/4" sheet of plywood was something I already had, but paid around $40 for. The plenum glass was around $15. I had the 608 skate bearings on hand, but they can be had for around 0.55 each from vxb.com. Your largest cost is going to be getting the parts cut - I have my own CNC router, so my cost was 0. :) The cameras use a custom firmware called CHDK that allows the Pi Scan software to control the cameras via USB cable. The camera's focus and zoom are set at the beginning of a scanning session. You can also adjust zoom at the same time. The firmware change isn't permanent though. You copy it to the SD card and then set the read-only switch on the card. When the camera boots, it sees that switch setting and reads its firmware from the card.

I am! I'm in the process of putting together a new video to show the new book cradles I built, as well as the other elements of my scanning setup. Thanks for asking!

PiScan is the software that runs on the Raspberry Pi and processes the data from the cameras. It saves them on to a USB thumb drive. I then put that drive in my PC and process the images with ScanTailor Advanced. I control PiScan with a touchscreen monitor that's plugged right into the Pi.

​@@f15sim OK!!! Thank you for help!

If I was going to be showing someone how to use the software, I would have captured it at 1080 instead of the 4k resolution of my main display. Sorry if it was hard to see.

Because PiScan is open source, you're able to modify it however you like in order to meet your needs. So yes, it's technically possible to do what you want, but you'll have to do the programming for it.

@@f15sim Ok dear friend! I'll analyze how to do and try! Thank you and best regards!

Thanks! However, I didn't invent it, I just bolted it together. :)

The Canon Elph 160s that I'm using with this setup is good for (I'm told) 300dpi. To get 600dpi, you may need to use a pair of DSLR cameras.

The links to the plans are in the video description. :)

The sheets of glass form a "platen" that presses the book pages against the support "wings" under the book. This keeps the pages flat so that they photograph well.

Nope. All by hand. Page turning systems really only work for pristine, brand-new books.

I don't see any reason why not, but it will be VERY heavy. A full 3/4" sheet of MDF weighs somewhere around 90lbs/41kgs.

@@f15sim i thought that plywood was denser

@@GospodinJean Nope. Here's a great chart that shows the weights of various sheet goods: www.hooddistribution.com/product-weights/ - MDF comes out at about 102lbs for a 4x8 sheet @3/4" The heaviest plywood on the list is Russian (Baltic) Birch at ~96lbs for a 4x8 sheet at 3/4".

@@f15sim thanks. I always thought otherwise

@@GospodinJean You're welcome!

What part of "DIY" is unclear? :)
