RE: Location Detection

Dave


Within the support section of gumstix.com, we encourage postings of projects 
like yours.

you might want to make a posting at the "gumstix in education" page

http://www.gumstix.org/tikiwiki/tiki-index.php?page=gumstix+in+education

or on the "robots and uav" page

http://www.gumstix.org/tikiwiki/tiki-index.php?page=robots+and+uav




This may help spread the word about your initiative and help develop other 
schools/people's interest to form an annual competition.
