I better say something about the lighting to use; if you go through Daniel Reetz's link:http://www.instructables.com/id/DIY-High-Speed-Book-Scanner-from-Trash-and-Cheap-C/and other links off that one, you will find a lot about lighting ...
Even if you buy all the materials you could build this copy stand for under A$30 and take less than an hour. Like me you will probably find most of the materials around your house or well stocked workshop.
To make one you will need: (This list looks long but it is very comprehensive; mostly nuts, bolts and washers.) A camera (preferably >3M res. or greater) A remote shutter release (optional but a darn good idea). Power adaptor for the camera (optional but a darn good idea). Optional USB cable for the camera. A flat base board 2 inches bigger in width & length than the pages you want to scan. 3x 8mm threaded rods (length depends on camera, see below) 1 x ¼” threaded rod length roughly enough to go halfway across the width of the board 3x lengths of ~1” aluminium angle extrusion, (length depends on base board, see below). 1x ½” long ¼” round headed screw with nut and two washers (pivot) 7x Rubber Tips to suit the 8mm threaded rods. 1x 8mm round head bolt screw ~1” long 13x nuts to suit the 8mm threaded rods (lots of nuts = lots of adjustability.) 14x washers to suit the 8mm threaded rods 4x nuts to suit the ¼” threaded rod (one of these can be a wing nuts for convenience. 1x 2”long ¼ “ 20 TPI bolt to suit your camera mount thread. 1x Bottle cap ~1” diameter. 1x Washer for the camera mount 1x Bicycle rear view mirror – as cheap as you like but easily adjustable. 1x ~4” piece of tubing the right diameter for the bike mirror. 1x 5” long ¼” round head bolt. I used a ¼” coach bolt. 1x nut to fit long bolt. 2x washers to fit long bolt; one should be the same diameter as the tube if possible. 2x desk lamps with little diffuse spot light bulbs or a single desk lamp with a reflector. (see below). Some scrap corrugated cardboard or similar page centring stops. Masking tape. Fabric book binding tape or thin rubber tape if you can get it.
Tools: A square A saw to cut the aluminium extrusions A tape measure and pen A file and/or emery paper A drill and drill bits Adjustable spanner or a couple of spanners the right size Screw driver
Optional tools: Drill press, small pipe cutter, gauge block, scissors, deburring tool, centre punch, craft knife or scalpel.
