Here is a great video on the Hackerspace in San Francisco and the movement in general. https://www.youtube.com/watch?v=wamwklXWK4M
We have one in Santa Barbara that is devoted mostly to 3D printers currently. I didn't see any audio projects going on. Typical of Santa Barbara.
The space in SF has analog, circuit hacking and audio going on in addition to digital. Does anyone know of a space with a large audio following? Perhaps one could be started. There are lots of digital hacker spaces but I see few are devoted to analog, which is an entirely different skill set.
