Hi,
since some years, the DiY DSLR scanner project is popping in my mind again and again, but actually never headed of to start it. I really like the idea, I can imagine I like the handling. I am a bit concerned regarding the sharpness / DOF thing and mainly to get a good light source to scan color sheets / negatives.
During reading another post regarding the v850 scan quality (again thinking about buying one...), somebody mentioned advantages of drum scanners again... Sure, old, used, nobody knows how long you get spare parts. List goes on and on. No option for me. Definitely.
Then it struck me. Is it possible to build a drum scanner on your own as open source project?
What do you need:
- A rotating glass tube of good optical quality (expensive for sure).
- three photomultiplyers
- a light source (in the center of the tube?)
- a photomultiplier moveable along the center axis of the glass tube
- electronics to read out the stream of the data from the photomultiplier
- software to display the data and control the whole thing
For sure, this a completely naive view of the whole project. I have no idea where one could get a glass tube of needed quality and the price point the same goes for the photomultiplier... Nether have I used a drum scanner, nor do I know exactly how one works...
As I am software developer and have some experience with tinkering around, I could cover this parts of the project.
Does anybody here know enough about the technical details about the glass tube, the photomultiplier and electronic side of the story to decide whether this whole idea is crazy or feasible?
