Excerpt taken from Wikipedia:

In general, makerspaces function as centers for peer learning and knowledge sharing, in the form of workshops, presentations, and lectures. They usually also offer social activities for their members, such as game nights and parties. Makerspaces can be viewed as open community labs incorporating elements of machine shops, workshops, and/or studios where hackers can come together to share resources and knowledge to build and make things.

Many makerspaces participate in the use and development of free software, open hardware, and alternative media. They are often physically located in infoshops, social centers, adult education centers, public schools, public libraries, or on university campuses, but may relocate to industrial or warehouse when they need more room.

The community-building, learning and innovation potential of hackerspaces has been explored. Makerspaces can be seen as vehicles for citizen-driven transformation and, thus, play a key part in a more inclusive, participatory and commons-oriented city.
