Being a total novice of all things electronic, I'm saddened by the program being postponed. By no means is that intended to reflect negatively on the original poster, Steve, whom I understand is busy with his backbone software. I've enjoyed reading about the HP electronic dog whistle project and didn't skip ahead any in the pages to ensure I had an idea of what was going on.
But with my neighbor's dogs still barking into the AM, even after I very politely approached them about the issue, I'm still hoping for a solution. I think I'm going to proceed in spending appr. $300 for this stuff to soundproof my window in the meantime, perhaps it'll help some fellow posters:
SOUNDPROOFING A WINDOW WITH A PLUG. If I do plug the window, I will make sure to come to the thread and post my experience and results. I agree with Steve's reasoning earlier about how we shouldn't be looking for "a solution" but "
the solution". I just wish that I had enough technical expertise to be of any use here on this message board. I have noticed there are many other great minds and electrically savvy followers reading the page.
I think I wouldn't even need the bark sensor and relay, I would be happy with just the manual blast (via remote control) that would hopefully dissuade the dogs from barking. I know nothing about electronics, sans the eng physics 2 course that I just took last semester (and finished with flying by the seat of my pants!). I find the geometry and physics involved to be very interesting, e.g. the resonant frequencies, the shape of the horns, or perhaps something like a parabola. The electronics part is definitely where I have no foresight (well okay, I have no foresight in anything, just an interest and a need!).
Has anyone managed to create a prototype and find success? I do remember reading about someone having their cheaper piezo tweeters fry out on them; I don't know if they ever got to the animal test-phase.
Hope we can keep the thread going! Come back Steve (when you find the time of course) to this wonderful project, the world needs you and your physics prowess!
