DIY Book Scanner

There are two other constraints here. First, there will be a maximum and minimum distance from the camera which can remain in focus. The camera must be in this range of distance from the page. Second, since the page must be well-lit, the camera needs to be at a sufficient distance away so that it wo...

I was doing some research and it seems like JPEG actually preserves fine details pretty well. JPEG compression artifacts are much more likely to happen on large areas that are mostly the same color. Having said that, lossless is clearly better for archival purposes either way. Preserving detail 'pre...

I have not seen this pattern with the focal plane before. I have seen the slight offset of the center when zooming in/out but that seemed innocuous. So it seems like there are two possibilities. One is that your camera has an unusual defect. The other is that your camera isn't actually aligned with ...

You've hit one of the fundamental limitations in the possible quality provided by cheap point and shoot cameras. The focus on every camera is based on the distance of the target from the lens. On a properly aligned book page, the distance between the center of the page and the lens will always be le...

Johannes, I believe that the cradle wing is in there as well. You won't want to cut it out of 19mm baltic birch plywood. You will instead need to cut it out of 12mm plywood. If the cradle wing isn't part of that file, let me know and I can link you to a DXF for just the cradle wing. That may be the ...

rduz, it looks like you might be going with a different setup now (one that doesn't use Pi Scan). But if you still want to resolve your Pi Scan issues, let me know and I will be happy to help you get things working. As an aside, there is another alternative to Pi Scan called TwoCamControl. This is a...

The link at the top of the page should be fixed. Please let me know if you see any other broken links that need to be fixed as well.

gutto12, I see the broken link and I will repair it. I'll post here when it is fixed (should be within a day or so). However, this is an older model scanner which has since been replaced by Daniel's Archivist design. The Archivist is much better documented and can also be cut out with a CNC. Take a ...

That scanner is a 'hackerspace' model. You can tell because of the all-plywood construction including a plywood handlebar. If you want to upgrade the lighting for that scanner, there are two threads you can pull. First, you can buy high quality LEDs rather than the lights you bought for it. SORAA 00...

Ok. Looks like I've managed to fix this. Give it another try yourself.
