I would like to hack my LB3500 to weed-eat on the way to the mowing area, or on the return trip home. Does anyone know enough about the motherboard to guide me towards a way to generate an input to an Arduino board or similar to control an electric weed eater?
It seems simple enough - just adapt a small weed eater head, sort of like the side brush on a Roomba. The weed eater only needs to be running when the lawnbott is driving on the wire.

No one has dove into anything on the motherboard that I am aware of. If you feel frisky enough, please provide any technical details you come across.
Just for conversation, I would look at the parameter wire sensor. See if you can figure out how to tap into that, or what the output data looks like (I'm guessing it'd be 1/0) and then watch for it to go into whichever state is on the parameter wire, tell your board to wait 5 seconds and if it is still on the parameter wire, it's probably going home. You may still get false alarms in the corners where the bot may be bouncing around the wire for a bit, but you could probably compensate for it.
