Wonky Wire - Tone Producing Electronic Kit
The Wonky Wire circuit is based around the same oscillator that is used for the Flashing LED Lights. The timing components (R1/C1 and R4/C2), however, are much smaller and this produces a much higher oscillation frequency of about 3KHz (3000 cycles per second).
To hear the high-pitched tone a high-impedance piezo-electric speaker is used. Notice that the piezo is connected between the collectors of transistors TR1 and TR2. The collector voltage of TR1 oscillates between 0 and 9 volts, as does the collector voltage of TR2 but in the opposite way. This has the desirable effect of producing a voltage variation of 18 volts across the piezo making it sound much louder.
The Wonky Wire is used to test the steadiness of your hand. You can see from the circuit diagram that when the wand touches the wire the oscillator is switched on and a tone is produced. Wonky Wire tone oscillator electronic kit. User assembly and soldering is required.
