DIY Book Scanner

Pi Scan does not yet support the Pi 4. I have purchased one and hope to be able to update Pi Scan to work with it soon, but I don't have a timeline for that right now. If you are planning on buying a Pi just to be a scanner, I would say just to get a Pi 3 since I don't expect the changes to the Pi 4...

I'd recommend that you read through the entire set of documents on the Archivist scanner here: http://diybookscanner.org/archivist/ This includes links to all the design files and descriptions of all the parts necessary. The DXF design files themselves are linked from there as well. Just go to the b...

You should expect about 4 seconds per cycle which is roughly the same speed at which you can safely turn the page when you are in a rhythm. However, the exact speed will depend on the external storage (thumb drive in the case of the video), the quality of the camera (higher end cameras produce large...

The secondary reflection from the other side is only completely absent at 180 degrees (flat platen). As you decrease the platen angle more and more, the secondary reflection will slowly spread from the gutter side and eventually if you had a 0 degree angle (completely parallel), you would see a comp...

Get power adapters right away. Taking cameras off mounts to change batteries is really terrible. I had to do that on my first setup and I still get nightmares.

konos92a, your scanner is looks really good. I get mad scientist vibes off of it in the best possible way. Just to be clear, though, looking at the image metadata generated by the camera won't give you an accurate idea of what the DPI is. That is a piece of metadata which every camera adds but which...

Hi. Just FYI, the Archivist bookscanner was a successor design to the one this thread is about. If you want to make an Archivist book scanner, head to: http://diybookscanner.org/archivist In the discussion on glass there, it mentions several options including grinding the panes to a 50 degree miter,...

Looks like you are finding a few issues in TwoCamControl. Maybe you will have better luck getting support by submitting tickets on the github page? The author of the tool asked for bug reports to be submitted there.

Canon's cheaper point and shoot cameras (like the A2500) do not have an independent aperture setting. The aperture range listed in the spec is how the aperture changes as they automatically adjust based on zoom level. DSLR and mirrorless cameras will give you sharper images regardless and since you ...

PocketLibrarian, I'm the author of Pi Scan so I'm happy to work with you to debug your issue. You can PM me or start a new thread (this is not the right place for it). Other than that, I'd say that TwoCamControl is a great controller system. And Using a USB trigger like Konos93a describes is also a ...
