Ken has a great idea about the motors project.
Two of our team's students won major science fair awards in physics/engineering with motor projects. (Wonder what gave them the idea?)
Look for Ryan M. and Brian C's projects on this page:

Ryan and Brian are both registered on ChiefDelphi and you can contact them here.
Also, our Question of the Day Archive has the robot from the floppy drive project (Question 30) with several links to the project.
