Experiments in Echolocation by Rodolfo Acosta Castro

70% of the bat species use echolocation to hunt and communicate. The ultrasound signals that bats emit are above human hearing, but we can bring them down to our perception with some electronics. Let’s build a couple of Bat-detectors and let’s search for bats at the Soča river when the sun comes down. 

No bats? No problem! We can steal the bats superpower and build a small square-wave synth secretly screaming for attention. 

Rodolfo Acosta Castro is a Berlin based artist working with electronics, code and nature in theater context. He will try some experiments with ultrasound transmitters and is happy to collaborate with other projects, to improvise or use new materials.
