hi,
i have 2 Golden Retrievers in the garden, but they are able to make to much trouble.
The solution where a dog fence. It contains a radio transmitter, receiver, and a long wire as antenna. The transmit frequency is n*10kHz. If the receiver is near to the antenna (buryed in the garden, next to the object/plant which is forbidden for the dog) it makes an ultrasonic noise, or vibrates in the neck of the dog..
did someone build such an device? I Need to comstruct one.. the ultrasonic/vibrating part is not the problem.. Just the transmitter/receiver section. It must be stable enough to be sure that no unnecessary alarm happends..
can someone help me with some schematics, ideas?
I know.. it's possible to buy such a device from ebayfor 200-250$, but with shipment and dutyis it to expensive.. and i need 2 of them
I think, that it is a simple circuit, but I'm not an expert in RF design..
