In this episode, Bhavisha Panchia speaks to artist Constanza Piña about her work as Corazón de Robota, her DIY practice of building instruments and synthesizers, and her long-term installation and performance project Khipu / Electrotextile Pre-Hispanic Computer. Piña discusses the khipu as a ‘speaking knot’ and transmitter; how we might think of electrotextile computers; the role of cosmotechnics in reading and understanding systems of knowledge; and the importance of artistic speculation in reimagining alternate possibilities. The two excerpts are recordings of her performance as Corazón de Robota at Bar Neun on 17 September 2025.
