Hi guys,
    I've been trying to scrounge some sonic range sensors, rather than 
buy a ping off the shelf.  Being unable to acquire an old polaroid 
camera to dismember, I looked around to see what else used these kinds 
of sensors.  Turns out those car backup sensors are sound based.  I can 
get a kit with a set of four sensors for less than the price of one 
ping.  However, I don't know how hackable these things are.
	Anyone out there ever messed with one?

Thanks,
