The "Insect Buzz" are sonic hand-held placards developed by Paul Granjon during his EASTN-DC residency. Featuring a simple microcontroller and contact speaker, the "Insect Buzz" emit a variable square wave similar to an insect in flight. The placards are made to be used in environmental protests, making some noise for reminding people that insects are dying and for a more ecological lifestyle. The talk features details about concept, fabrication and deployment.
