Urban Cricket is a small circuit that imitates the call of a cricket, only being powered by a small solar cell. The idea comes from Reinhard Gupfinger a Linz based artist I met during the Ars Electronica Festival 2011 in Linz. This circuit here is a altered version of his original circuit. He distributes this little sound bugs all over the world. Until early 2013 on was in a tree at the Schwedenplatz in Vienna.
