The electronic rodent repeller circuit is composed of the timer circuit, mew generator and power amplifier and other components, and the circuit is shown as the chart. Timer circuit is composed of a time-base integrated circuit IC1 and the non-steady-state multivibrator composed of the related external components. Mew generator consists of integrated circuit IC2 and transistors V and so on. Power amplifier consists of integrated circuit IC3, and related peripherals RC components. R1 ~ R5 use 1/4W or 1/8W carbon film resistors. RP1 and RP2 can choose small solid-type potentiometer or variable resistor WH7. C1, C3 ~ C7 select aluminium electrolytic capacitor with the voltage in 16V; C2 and C8 select ceramic capacitors. VD1 and VD2 use 1N4148 silicon switching diodes. V uses 590I3 or 3DG12 silicon NPN transistor.
