Unfortunately, due to unforeseeable circumstances, our group did not
make as much progress as hoped.
However, the
small progress that was made included the delivery of parts and new
information. The solenoid valve and other parts of the ballast tank was shipped in early this week
and the depth sensor arrived shortly after as well. The other vital part still needed is an
Arduino board. The group was hoping to secure one from by checking it out of one of Drexel's
Engineering labs. However, after talking to the advisor in charge, we found out that if we decided to carry on with this aspect of the project, we would have to spend more of our funds to order one.
After a quick trip to the machine shop, the ballast system can now be assembled. A 1/2" clear tubing will be used to connect the pump valve and ballast tank. The ballast tank will be a PVC pipe with a barbed hose connection on the bottom so that it can easily be connected it to the rest of the system.
