What is Stratum 0?

Stratum 0 (Wikipedia-W.svgIPA: [ˈʃtʁaːtʊm nʊl]) is the hackerspace in Braunschweig region, Germany. It is a place for entities interested in technology, hacker culture and creative usage of things to get together and exchange, keep up Hackerculture and being creative with technology. We see ourselves as an open Space, so that interested come by at every time (provided the Space is open), without being a member.

Since January 2014 we got a 164 m2 (1,765 ft2) big Space. To maintain the Space and its infrastructure, new members are always welcome.

The name comes from the Wikipedia-W.svgNetwork Time Protocol. We chose this name because there is an atomic clock at the Wikipedia-W.svgPTB which provides the time for Germany.

How to get to know us?

We consider ourselves as an open hackerspace, you can join us every time the status badge on the left says „open“, without the need to be a member. If the space is closed, you can also ask when someone will be around on IRC or on the mailing list. For a lot of our activities you can also check out our Event-Schedule (listed below).
