Build your own electromagnetic listening device/recording instrument, the “Elektrosluch Mini,” in a special workshop led by Slovak experimental artist and musical instrument creator Jonáš Gruska.

Designed specially for the event, the mini edition of the Elektrosluch is an open-source device for recording electromagnetic signals. With it, you can discover the sonic worlds of electromagnetic fields, an invisible but ever-present part of our environment. After the workshop, plug in headphones and explore your surroundings.

Here is how it works and sounds:
