@Mark Boyce posted:Steve, that is a pretty slick installation. I am assuming it could be positioned so selected sounds could start when a train goes by.
I'm assuming so, but I actually had the reverse problem -- passage of *any* train on the adjacent track would trigger a random "nature" sound, every time, so to avoid that, I had to place the motion sensor in the bottom of the 'hot tub', so activation occurred only when something moved *above* the sensor, like someone bending over to view the scene. It works pretty well, and in fact, since the sensor actually looks a bit like a cooking vent IMHO, it should be easy to add to the diner!
