	Some one in sci.aeronautics mentioned using a device called a 
	"hotwire anemometer" to measure windspeed across a aircraft
	wing. I've heard of these things before (I think the Voyager
	Mars landers used one) but have never been able to find out 
	many details of how they work and from what/how they are made.

	Anybody know anything about these things? Can one fairly accurately
	measure wind direction as well as speed? I'd like to use this for
	a home weather station. Any and all assistance is appreciated.

	Thanks
