This looks cool:

Greenbrae Mini Maker Faire (Sat Sep 14) will be Marin’s largest “Do-It-Yourself” festival, showcasing local makers with activities, show-and-tell, and exhibits on arts, crafts, science, robotics, music, technology, sustainability, education, food, and creativity.

Greenbrae Mini Maker Faire celebrates the imagination and ingenuity of our community, with hands-on learning and creative activities. It’s a day of sharing knowledge and talents in a family-friendly event that is fun, entertaining, educational, and encourages the “maker” in all of us.

The Greenbrae Mini Maker Faire takes after the popular San Mateo Maker Faire [see MVGATE’s visit], but is a smaller, Marin-focused event featuring maker booths and interactive demonstrations and projects, including 3D printing, do-it-yourself kits, aquaponics, upcycling, recycling, adult and youth maker spaces from around Marin, and numerous robot-related activities and demonstrations.
