Built a scanner? Started to build a scanner? Record your progress here. Doesn't need to be a whole scanner - triggers and other parts are fine. Commercial scanners are fine too.

Hi,

I would like to share the book scanning stand from Hiroshi Yanagisawa called Book Shooter MK-V

It's a book stand for easy book scanning with a smartphone (book handler)

Interesting design. How well do the book scans look?

I also like this design and made myself similar device.
I applied following modifications:
1. made of 3 mm High Impact Polystyrene Sheet (HIPS);
2. the construction is glued and reinforced with screws and L-shaped elements (sheet are rather thin so glue itself doesn't give strong enough bond);
3. white color inside in order to have better light distribution (upper part of a page photographed is higher distance from the light source than the bottom part), however the white interior reflects the light and helps a page to be lighted more evenly; still far from perfection, though;
4. the lightning is different construction: I made it of LED tape (5 V, so it may be powered with standard phone charger or a powerbank) fixed in four rows to a rectangular board mounted in the bottom part of the bookscanner near the glass; owing to this the construction is very compact and portable, no any initial setup is necessary before starting scanning;
5. however I'm not fully satisfied with the lighting as due to using "warm white" LEDs (2700 - 3000K) pictures are somehow orangish, "neutral white" (4600K) may be better for this;
6. I use iPhone 7 as a camera (12 mega pixel), there is distance of 18 cm and the "physical" density is approx. 470 DPI.

I attached a sample picture. Quality a little bit reduced in order to meet the filesize limit.

The orange tone is usually not a problem. Pages with text may be binarized with no trouble (white background black letters). If preservation of color is necessary, the white balance may be easily corrected using software method.

i made 2 scanners for one camera or smartphone and i scan some small books to see what mistakes happen rather than a 2 camera diybookscanner
.
i realize that with a bluetooth trigger there are connections problems and i need to reconnect after some pages.
i want to watch if with a cable trigger there are connections problem. i will buy one with a 3.5mm Jack with 4 pins (like headphones)and try to make an electric trigger.

iPhone 7 is not equipped with jack audio connector so it may be difficult to find a cable trigger. Maybe lightning jack adapter may help? I haven't tried this. I also encountered some connection problems with this bluetooth shutter, but only minor and find this the most convenient solution.

I did not made this book shooter. I was just interested by theory of its design.
If i found an industrially made wooden book shooter, i will surely buy one and make a try.
