According to its website, Noisebridge is "an infrastructure provider for technical-creative projects, collaboratively run by its members." In other words, an awesome maker space. It's overflowing with electronic parts and creative people.
They hold some regular events like Microcontroller Mondays (a time to build small electronics projects) and Five Minutes of Fame (monthly lightning talks on all matter of subjects). Check their website for event dates and times.
