The c3RE is the hackerspace in the Recklinghausen district in the northern Ruhr area and feels connected to the chaos community. In line with the values ​​of the Chaos Computer Club, we promote creative tinkering and technological innovation.

At this year's congress, you can create and produce your own buttons with us. Due to the huge demand at the 37c3, we will only be doing individual buttons as part of SOS this year. So keep an eye on the schedule.

You can also become part of the "Filament against the Right" campaign. You can find out exactly what that is in our assembly.

If there is no congress, we do a lot more...
