Dog Repeller. I ask for recommendations for manufacturing.

So, what do we have - ultrasound and shockers.
A simple homemade suggest? preferably based on a siren from an alarm.

Leo, my friend. Aliexpress to help. The issue price is low.
It is for you inexpensive ultrasound
Or ultrasound with two emitters
Quite cheap in sound range 120 db alarm
Instead of the sensor, simply solder the fixed button. The brain makes a squeal reliably.
And in order to recommend homemade, you need to know what parts are available to you.

hehe haha. What about the solution? My child goes to school through the village, and there is a dog.
In the early 90s, we tried to produce ultrasonic rodent repellers. It turned out that the mice did not respond to them, and the rats left within a few days.
a dozen ultrasonic mouse repellers

I personally saw mice climbing on them,

And the mice reported on the appointment of equipment? Have you been instructed (by signature, of course)? smile
So what we have is ultrasound
- He worked in one organization, they bought a dozen ultrasonic mouse repellers there. I personally saw how the mice climbed them, they probably liked it-))) And on my old Nokia, even on the Symbian, a mosquito repeller was installed, so it worked. There were no mosquitoes within a radius of 1.5 meters from me.
cool so what

Google "dog repeller", I get:
Results: approximately 3 320 000 (0.29 sec.)

There are many reviews, by the way, the wrong repeller can trigger an attack! Be careful with homemade products, especially with emitters that are unable to reproduce ultrasound! Therefore, I'm kidding, a person, not plunging into the topic, asks a question and awaits a ready-made solution. smile

whistle
And what, in fact, does not suit "matyugalnik" a megaphone or just a tin shout and bark into it? xaxa
Half of the answer has already been voiced in the wording of the question itself.
So need a little loud viewer?
The siren from the signaling with batteries will be too big.
You can buy an ali water leak detector. Little and evil thing on the crown.

But in the open, you need to try. And so that the dog is not deaf.
Aah! Here's another:
It is possible to approach the dog, throw it to the ground, trample the heel with a strong blow, and then, turning and making a terrible face, say to the dog:
- Now I’ll do the same with you !!!!

Nnu ... I don’t know ... I would be scared! ))))
Well, perhaps, it’s the same - on a long chain and twist around yourself !!! You can scare too ... Only then, preferably, immediately jump into the center of the pack! ))))
preferably based on a siren from an alarm.

The mouthpiece itself (even burned out) can be tied to the end of a long pole! ...
And with a bang-and-whack to her at the withers KHRING !!!!!!! )))
Sorry ... Nothing else comes to mind! ))))
