Come out and join some of the Baltimore Node members at the Baltimore Hackathon June 8th-10th, 2012. Should be a good time to bust out that dusty Arduino of yours and put it back to good use, plus you might even win a prize. Ticket includes t-shirt and tasty food for the weekend.

Hope to see you there!
