I found an article in an old "Electronics Now" mag that shows how to build a
wind vane. It uses a rotary encoder and a 74HC154 decoder to light the
correct LED for display. My problem is that they say the sensor will work up
to 30 feet away. I would need over twice that distance to use this in my
home. Does anyone know if it is possible to boost the signal for this, or
some other way to make an electronic display wind vane?
