For a while I was considering converting it to a near IR camera, but I was reluctant to make another one after having already made one for 62 Projects to Make with a Dead Computer (p. 200). However, I changed my mind about this when I learned that it was possible to use the material inside floppy disks as a visible light filter (for viewing near IR light). This sounded really cool and so I decided to give this a try. Not only does this totally work, it also adds another level of computer reuse to the version demonstrated in the book (as it provides a way to reuse floppy disks in addition to cameras).
It has been fun going around shooting pictures and discovering all of the interesting results when I upload the photos at home.
Step 1: Go get stuff
A (somewhat) broken (or antiquated) camera
A floppy disk
A mini screwdriver set
Step 2: Make a visible light filter
Rip apart the floppy disk and be careful not to get your fingerprints on the plastic disk.
Take the disk and cut a small plastic square that is slightly larger than your CCD.
Tip: To make sure your floppy disk lets IR light through, go to a window and look outside with the plastic held up to your eye. You should be able to see through it.
