Hi @notengobattery the project is already finished FYI. I checked its oscillating.I think there is a problem with transformer what can i use instead of it? Sound frequency at this level are classified as ultrasounds and could be used in a number of trial and error and functional applications. This becomes possible since these animals are able to easily detect the frequencies at this range and find it disturbing in their ears, while humans remain unaffected due to lower hearing range. Many commercial pest control is based on this principle driven manufacturing, usually in their frequency range between 30 to 50kHz. PIC16F873 Ultrasonic Range Meter - On these pages, I will introduce the Ultrasonic Range Meter with PIC 16F873.

In frist set will consists of TR1 and TR2 are used to generate a low frequency by have C2, C3, R1-R4, LED and VR- 100K, which it is the frequencies generators to Collector of TR2. It's well known that many animals are particularly sensitive to high-frequency sounds that humans can't hear. You have to fine-tune he trimmer potentiometer P1 to generate a noise having the identical throw, matching the insect's range you would like to repel. Thank you for answering. https://streampowers.blogspot.com/2012/09/circuit-cat-and-dog-repellent.html Here is the circuit diagram of an ultrasonic mosquito repeller.The circuit is based on the theory that insects like mosquito can be repelled by using sound frequencies in the ultrasonic (above 20KHz) range.The circuit is nothing but a PLL IC CMOS 4047 wired as an oscillator working at 22KHz.A complementary symmetry amplifier consisting of Hey! This is small and cheap because use transistor (no ICs) and super loud since use large piezoelectric but use low current source. To find out more regarding the circuit or to improve its effectiveness: Using an uninterrupted sound frequency to repel or attract insects may actually be possible in real life. The piezo elements are rated for +- 30V. R2 is superfluous. Each of the parts and the power supply could be enclosed in a compact plastic-type container. With this cool cat/dog repeller circuit you could chase the cats off from any where you want.
