research in the framework of Seed Journey - Futurefarmers with bolwerK
and support of the Flemish Community


Antwerp: Extra City

Performative event - open lab

hosted by Azahara ubera Biedma, Bert Balcaen, Ptr_, Marthe Van Dessel

Pirate radio transmission + Balloon mapping

During a performative event we develop strategies to commonize the electromagnetic field as evidence for an alternative, community-owned definition of land, air and frequencies. Antenna's and voicing on different frequencies (fm, wifi,...), signals the electromagnetic spectrum as a critical natural resource. Tune in your radio on 108FM, download a SSTV demodulator and follow the radio balloon live from the rooftop of ExtraCity. Open hardware and devices co-opted from Public Lab, a grassroots citizen projects and research group, collectively embodied in a social choreography.

10 September, 5pm

via local radio 108 FM + streamed on Radio Ruelles

Open lab – Demonstration - Performative event - Workshop

Navilogger, Pirate radio transmission, Balloon mapping

During an open Lab and performative event, we 'try_out' different devices which can be co-opted by grassroots citizen projects and research. We will initiate how to program microprocessors, and execute scripts via command line. Learning by making and doing, we develop tactics and strategies to commonize the electromagnetic spectrum. We retrace our route, map the area (port) and make pirate radio transmission on a very local scale (images, text, audio, data, morse,..). Bring your Computer (linux, mac) with ethernet port AND/ORphoto camera, AND/OR other devices .

bolwerK is a transuniversal constellation that has been initiating, mediating, facilitating, curating and appropriating local and international projects since 1998. Social environments are created, not for streamlining ideas, but in order to formulate common questions, shared praxis and hence feed a sense of communality.
