Ultra-sonic teenager deterrent Answered
I've seen kits and plans online for ultra-sonic teenager deterrent devices but I can't imagine that they are all that complicated. There is a large group of teenagers that hang out smoke, litter, stall traffic and make a great deal of noise across the street from my home. I believe that having one of these devices and hiding it within range of them somewhere on my own house would be a great way to get them to disperse to somewhere else. If anyone has made one of these devices and would like to share their design I would greatly appreciate it.
