TdS Report #17: Team Profile: Zodiac

David Marshall teaches technology and engineering at the Irondequoit New York
High School and advisor to the Technology Club that build the "Zodiac". It was
entered in last year's Tour de Sol.

"This year they totally rewired the electrical system to shorten wires and
place components in better locations. We went totally to digital-link meters,
replacing the analog meters. We lightened the car by replacing the bottom pan
with graphite. The rear swing arm (off a motor cycle) has been rebuilt. A
dual air-shock lets us adjust the ride height and dampening rate. The solar
panels are rewired and now give us about 3.5 Amps at about 62 Volts," which is
charging voltage for their 48 Volt battery pack. "We have a sensor to monitor
the motor temperature."

They worked on the car all year since the last Tour de Sol. They now have an
enclosed trailer which is getting solar panels so they can recharge the car,
laptop computers, and cell phones. There is 120 Volts AC on the workbenches.

"The kids can get credit with this if they go through the guidance department
and put in the hours and activities that meet ciriculum standards. We get a
lot of kids in that don't play sports, are not into music. It's a great place
to go after school, get dirty and have some fun."
