I would like to build a tracking device that will help me track my grandfathers ferrets when he is working them.
I have seen loads of fm transmitters but I cannot find any whose transmitters would be small enough or have components that are not obsolete. The transmitter would need to fit on a collor so would need to be about the size of a thumbnail.
The range would only need to be around 15 foot though the transmitter wll be underground.
The receiver could be handheld and i would like it to beep in a higher pitch the closer you get to the transmitter.
Does any one have any circuit diagrams that would satisfy this?
or can you point me to a web page that might be able to help me.
thank you
