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.

Schematic description:

The Urban Cricket consists of three simple oscillators, a piezo beeper with built in driver and a solar cell for powering the circuit. The piezo beeper has a built in driver which means that a voltage applied will cause the beeper to generate noise not only a short click. It generates a tone at about 2,000 to 3,000 Hertz witch sounds pretty annoying ("piiiiiiiiiiiii").<br>
