In “What is Feminist Hardware? Feminist Hacking: Building Circuits as an Artistic Practice” workshop on 23-25 March 2021 in the frames of the New Materialist Informatics 2021 conference organized by the University of Kassel, Germany, we intervened in the hardware production cycle by connecting with ethical hardware manufacturers. We worked in a systematic manner with manufacturers who are specialized in open and ethical hardware to find as many fair sourced hardware components as possible. In this workshop, we proposed to experiment with circuits that consist entirely of these special materials we have collected in recent months. We believe the development of individual positions through collaboratively developed hardware to be the most appropriate way to demonstrate what feminist hardware entails. This methodology aims to support, on the one hand, the production of new knowledge acquainted by the interaction between artists, hardware developers/manufacturers, and, on the other, the playful prototyping with fair-traded open hardware.
