Dogs Barking

Hi
Has anyone built a high powered unit to stop neighbors dogs barking? Please help
Stray Electron:
You don't need a high powered unit. A .22 LR (Long Rifle) is sufficient.
Audioguru again:
High powered what? Sounds? Wouldn't dogs also bark at high powered sounds?
radiolistener:
there is no need for high powered device. Just buy dog repeller like this one: https://www.aliexpress.com/item/32979578797.html
When you activate it against barkling dog, the dog will shut up immediately and run away with its tail held between the legs :-DD
The exception is just deaf dog that does not hear anything.
It also works against cats. ::)
I can recommend to desolder leds (they consume more power from the battery) and to replace ultrasonic transducer with this one: https://www.aliexpress.com/item/32644794200.html
Because transducer that comes with device (in plastic case) is cheap and will be damaged very quickly due to high ultrasonic energy.
Also I recommend to use this Li-Ion accumulator for this repeller: https://www.aliexpress.com/item/32807381507.html
Because it consumes about 500-700 mA and usual 6F22 battery cannot handle such current.
You can also buy these transducers and make your own DIY repeller. All what you needs is just to put 24 kHz 60 V signal to the transducer. In order to get 60 V amplitude, you can use step-up transformer. And feed it with 24 kHz oscillator with power amplifier.
Here is frequency response of these transducers. I bought two pairs and they almost identical:

Hi
Thanks, these dogs are about 200M from my house out in the country. The sound seems to carry better at night and they bark all night, that's why I was asking about high powered.
Would your solution suffice?
