Electronic dog repellent, dog chaser schematic
Electronic DOG Chaser Repeller
The electronic dog repeller circuit produces a discomforting but not harmful, high frequency sound, audible to dogs but not to humans. Help stop the approach of unwanted dogs at up to 15 feet.
It uses 555 circuit at is easy to build, this is a dog chaser schematic that you can do it yourself
From R3 adjust the resonance frequency of the Ultrasonic Ceramic Transducer. 100Vpp were obtained at 30 kHz. Without piezo the output voltage is 200 Vpp.

i need from this transformer – give me out Voltage about max. 20V , i think use this piezo for safety from dog http://www.farnell.com/datasheets/81154.pdf
and i think use 3 piezo ( in parallel )

Circuit is pretty good
But Ther,s no value of Diode=D1,D2,D3.
& Transformer mention as EE15
please could u email me the values of Diodes
& transformer value so i can work on this pretty circuit of yours
Thanking You
