DIY Book Scanner

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 ...

I have played around with this. There are a few limitation of Raspberry Pi cameras. The 8 MP resoloution, the complete lack of zoom, and the fact that a single Raspberry Pi can only handle one camera at a time. But they are cheap. They have manually-set focus control. And they are relatively more re...

There are two possibilities that you might want to look into. First, you might just want to buy a large tablet computer whether an iPad or an Android/Microsoft one. For $300 you can probably get a last-generation refurbished or used model. Then you can use it as a large screen with an attached camer...

As far as I am aware, Spreads is no longer maintained. It is a neat project that I hope gets reborn some day if Johannes gets more time to work on it. In the mean time, you might take a look at TwoCamControl (a similar project for windows) and Pi Scan (a similar project meant for running on a Raspbe...

Just a quick update on this. ELPH 180 cameras are now supported by CHDK. So the camera situation is not nearly so dire thanks to the brilliant efforts of reyalp and others in the CHDK community. It also seems that Canon has pulled back from the yearly release-and-obsolescence cycle. So hopefully thi...

The 'drivers' for these cameras will be part of one of two projects: CHDK uses some hooks that are available in the cheap Canon point and shoot cameras to bootstrap a more full-featured environment onto the camera that also lets you control it via a computer. Porting CHDK to a new camera can be eith...

The only issues are that the two pages might not match exactly. If you are buying cameras, I'd recommend getting a matched set. But if you are using cameras you already have on hand, then I'd say give this a try and see if you like the result. There is no software or other insurmountable problem. -J...
