We have opened the schaltWerk in January. In the broadest sense it deals with a "Hackspace". The alignment is more towards art and less towards construction of robots. The later is naturally not missed out.
There is free entry to schaltWerk (you have to pay entrance fee for the entire Unperfekthaus). The room number is 203. Everyone who is interested in interactive art, Arduino, soldering circuit boards, etc. are most welcome.
