Hi everyone and thanks for a great informative forum. I've wanted to scan my books for quite some time but it wasn't until I found this site that I thought it possible on my budget.
My first build is a single camera scanner based on Antoha's single camera build. My requirements were, simple design, cheap and use of my current SLR camera. I liked Antoha's build but thought I could simplify it by laying it on its side. I have scanned a couple of books now and I'm amazed at the quality of the final product. It isn't a perfect design but it fit my requirements just right. The platen is made from glass from a couple of old frames of almost equal size and mounted vertically on an old corner shelf I had laying around. The corner shelf has multiple holes drilled in the bottom diagonally from the back corner to allow different size books to align with camera and swivels on a peg I have on the base. I use clamps to hold the base to the table and they double as stoppers for the platen to align up facing the camera. Lights where a couple of halogen I bought from IKEA for my kid's rooms. The trigger is an old ballpoint pen I have mounted a trigger on and soldered it to an old telephone cable laying around and then to an old flash cable that just happened to fit perfectly into my camera. Total cost for whole project: $2.99 for a trigger switch from Radio Shack.
