ClubArduino is an Oakland, California, USA based group of teachers and artists. We meet to help each other with our projects, to show our stuff and plan future meetings. All this over drinks and snacks in a nice setting. The next event is this coming Saturday the 14th of March, 2009 (Pi Day!) There is an invitation here: crush3r.com/page/gzkjglkhlf
