After converting all of the old 8mm films from my relatives I turned my attention to the hundreds of 35mm slides sitting in boxes.
I didn't want to pull every slide out and scan them individually but I still wanted decent quality in the scans.
To me the easiest way to do that was to use an existing projector hooked up to a Pi.
I had seen other projects that accomplished this by using cameras running CHDK or other external cameras but I wanted to see if it could be done with the Pi camera.
In the end I got pretty decent quality and the slides are preserved for future generations.
