Open Hardware in Atlanta
Yes, I know that technically this site is about open source software in Atltana, but open hardware is coming into its own. We've previously covered FreesideAtlanta. Now it looks like there are four people waiting for an Arduino meetup to form. For the uninformed, the Arduino is one of the current market leaders in open-source electronics prototype platforms. You can build or buy the boards, and the software development environment is open source.
