Simple Scanner Camera
1. Build the baseboard.
Cut a piece of black foamcore that fits exactly over
your scanner’s glass bed, then cut a 7" square hole
out of the center. This will be the baseboard for your
camera.
2. Make the boxes.
Make 2 boxes that slide together for focusing. Using
cardboard and glue, make a 7"× 7" inner box with both
ends open, and then an outer box with a lid on top,
slightly larger than the inner box, so that they nest
snugly together. Line all box edges with duct tape.
Cut a 3½"-diameter hole in the lid of the outer box.
3. Make the lens board and
aperture cards.
Remove the lens from your magnifying glass and
cut a hole in the center of a 6"× 6" cardboard square
to hold it. Tape the edges of the lens securely into
place on the cardboard (Figure A). This is your lens
board. Out of heavy cardstock, cut a set of covers
for the lens, with different-sized holes in the middle.
These are the aperture cards, which you’ll tape
