In September 2013, I gave a DIY Masterclass at SUPERMARKT, which is a lovely co-working and event space in Berlin. The masterclass was a sonic exploration into electronic textiles and about ten people participated in making crocheted sensors, which could be used for altering sound.

The workshop started with a brief introduction to e-textiles, after which the participants learned few basic crochet stitches. The idea was to crochet a piece which contained both regular and conductive yarn, and to connect it to an oscillator circuit. The circuit produced a constant tone, and the crocheted piece provided an interface for changing the pitch by stretching or squeezing it. These movements lowered the electrical resistance in the crocheted fabric, resulting in higher pitch. It was thus possible to play different tones with the noisy crochet.
