With the $50 survey coupon, I decided I would go ahead and do the LB3500-to-LB3510 upgrade. I suspect that my motherboard was dead, so this should solve that issue.
Now I want to be able to remote control my mower as described in this thread, mainly to help resolve various errors (bump, border, and blackout) remotely. I think I would like to add a camera as well.
Can you guys give me a head start with the wiring for the buttons?
