In an effort to teach myself Javascript, Java and
CGI programming methods, I have
created several Javascript utilities, some of which
are included below. Some examples were not worth including
here, as they were merely test cases and didn't do anything
of interest, but additional cases will be added here over
time.

A calculator for astrophotgraphy. This calculator works
for a camera lens system in addition to prime focus and
eyepiece projection through a telescope. Enter the appropriate
information for you photographic setup (film speed, lens
Fstop or telescope aperature, lens or telescope
focal length, film speed, etc.) and it calculates exposure
time and image size on film as well as working focal ratio.
The calculator also lets the user record any calculations
along with associatied notes to a list of calculations, which
can then be printed (great for field work!). Also included is
a small database of astronomical objects with their brightness
values and sizes.

A Hogwarts sorting hat based on the Harry Potter series
by J.K. Rowling. This sorting hat differs from most others
on the web in that it asks the user specific questions to determine
their appropriate school house rather than using a random selection.
Soon the sorting hat will remember the houses for people it has
already sorted.
