Wire guidance for robot lawnmower?

Thanks cr0sh. What a great idea! I'll check into it. :smiley:

I looked into it. Seems that the tracer sensor needs to be within a few mm of the wire. I need a sensor distance up to about a meter. =(

Thanks anyway!

Well - a meter would be problematic; but a few mm seems misleading (I used one of these to trace wires in the walls of my house; I certainly wasn't anywhere near "a few mm" of the wires).

Anyhow - that might just be a question of amplification? Maybe you could amplify the output in some manner of the toner transmitter (or amplify the receiver audio)? For as little as such a device cost, it would be worth experimenting with...
