I have no experience with these companies, but am very interested in your
finish line circuit design. We must modify our finish line circuit as a
result of last year's experience:
Each lane has a wooden dowel leaver suspended over the finish line. Attached
to this lever is a tube filled with mercury that, when tilted, completes the
circuit of an electric switch that turns on a light for that lane. This finish
line circuit worked fine for two years until ... (suspense building) ...
a parent with a camcorder showed that his son's car had actually won when the
light showed another lane. How? The car's sleek design was able to slip the
nose under the lever without tripping the switch until the car had traveled
further across the finish line! Now is that a photo finish, or what?!
An obvious EC (engineering change) is to extend the length of the levers.
However, I am interested in other successful finish line designs.
