c3RE is the hackerspace in the Recklinghausen district in the northern Ruhr area and connected to the chaos community. In line with the values of the Chaos Computer Club we promote creative tinkering and technological innovation. As every year, we offer PCB ‘coasters’ with LED lights in the Congress layout for you to solder yourself.

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

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