Urban Cricket
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.
A video demonstrating the functionality can be found here: Youtube video
Since it is hard to recreate a circuit not having a pcb an a schematic, people who want to recreate the Urban cricket will find the schematics, a layout to create a pcb and a parts list here soon.
