Paul Granjon has started working in the FabLab Cardiff on prototype objects to be used in forthcoming protests against climate change and ecological collapse. The Insect Buzz hand-held or backpack-mounted objects are imaginary insect faces painted on wood, that emit a persistent BUZZING. They act as a reminder of endangered insect life. At the back of the panel a contact speaker plays the continuously varying insect buzz approximation. The buzz is a square wave generated by a small microcontroller programmed with Arduino.
Paul has tested a back-pack version as part of Extinction Rebellion’s Summer Unrest event when the traffic in Cardiff city centre was blocked for 3 days. The plan is now to reduce the cost of the objects and publish the instructions for making them. The aim is to have many running at the same time, delivering a proper insect swarm effect.
