The 120 piezo discs in Souvenirs for Your Itineraries are driven by ten PCBs, each of which has 12 outputs. Each PCB has six independent audio channel and each channel consists of a voltage-triggering component (NE555 chip), an oscillator (CD4093), and an amplifier (LM386). Since each component (except the amplifier) is made of resistors and capacitors whose value is different from those of other components, they make different sounds at a different time interval. Furthermore, some of the triggering components are equipped with photo resistors, which randomize the voltage-trigging sequences depending on the ambient light.
