Hey guys this has nothing to do with machining but I've got a problem and I'm looking for some help. I've got a "neighbor": across the street who has been letting her dogs on my property. I asked her nicely to keep them off my property and she went ballistic and then proceded to tell me that she was on the homeowners association board and if I complained she could cause me a lot of grief. Every morning and evening she walks up to the edge of my lawn and lets her dogs out on those extend leashes about 25ft long. I don't blame the dogs she is in essence giving them the go ahead to roam the yard by letting out the leashes.
I've looked at the ultrasonic dog deterents as that would be a non conflict way to keep them off but reviews of them show shoddy workmanship as many die in a month or two or are weak, only proviving protection at close range.
Since I live in a neighborhood with a home owners association I can't put anything in the yard like a post near the road as it would "interfere with the mowers", small yards so everyone's yard is mowed by a service, so I would have to put it in a planting area about 25-30ft from the road.
I'm thinking of finding some high power ultrasonic transducers and try to build one that would reach the distance and still be strong enough to stop the dogs without harming them. I'd just like to keep them on the opposite side of the road.
It would need to be discreet and inaudable to humans with an on/off switch that I could activate from inside when she takes them out.
I really need some help on this as I don't know squat about electronics. Would this idea work? Where to buy the transduces and what type? How to go about building the device? or if anyone has access to the parts and could build it, let me know how much and if I can afford it I'll buy it.
