I am currently refitting a robot lawn mower.
This is my first project with anything remotely involved with radio type electronics.
The robot lawnmower has an electric fence wire that has a signal of approx 6kHz going around it.
I need to detect this that I can keep the robot in the perimeter.
I am ok designing a circuit for amplification etc but I need a resonant coil and capacitor
to pick up.
There doesn't seem to be coils just to buy of the shelf??? I am in the UK.
How many henries should I use? Where can I get them? Do I have to wind my own?
If so how many turns of wire should I use??
Thanks for any help.
