> Hackerspaces are open places for the creative use of technology. They not only provide tools such as 3D printers and electronics labs but also offer a space where hackers, makers, and tinkerers can meet to exchange ideas and work on projects together. Over fifty Hackerspaces will join in and open their doors nationwide and in Switzerland and Luxembourg. The spaces and projects are as diverse as the interests of the CCC activists who meet and get involved in them.
