This is an old revision of the document!
I'd been working on a device to photograph slides to convert them to digital form, and was about 75% done with it. I still had to finish the part that would hold the slides and light them from the rear. I had prototypes, but wanted to laser-cut the final working version.
I've abandoned it all, because I saw this: http://metrixcreatespace.com/post/20108216677/diy-slide-scanner-lets-say-you-have-a-large
So that's the direction I'm headed in now.
Below I'll post updates to this project as they happen.
The base is done, and it now holds the slide projector and the camera. I'm still finding the exact camera/lens combo that will work the best. Once that's done I'll do some tests and then move towards automating it all. (If the tests work!)
I have most of the base done, which will hold two platforms that can be leveled with thumbscrews. Once the mechanical build is complete I will be looking at using an Arduino to advance the slides and control the camera to capture the image.
