Planning for the break:

-Buy the extra parts that I need for my prototype:
Sandpaper, 400 grit and 800 grit - Available at hardware store
Brass Polish - Available at hardware store
8 x 10 sheet of Lexan standard thickness (0.85) - Available at hardware store
8ft strip of "Tile Divider" - Available at hardware store
-Build my final prototype
-Create a video to document my project.

Make an infrared lens for my webcam:

What do I have to buy?
-some black processed film (the black bit at the end of old negatives). This is the key element as unexposed (black) processed film is visually opage but IR transparent
- a square of hard plastic cover (from a file, or book), the thinner the better, as it is easier to cut, but fairly rigid and slightly larger than your camera's objective.
