I would like to build a home weather station with analog instruments showing for example temperature, wind speed and wind direction.
I would like to use a salvaged flight instrument to show the wind direction: I have a wind vane transducer that convert the wind direction in an electrical signal and I would like to use this signal to drive a suitable instrument.
The instrument I have in mind is like a magnetic compass but while the magnetic compass does not need an "input signal" I need to drive the needle.
I have a look at a heading indicator
but it seems to me that the "airplane needle" is fixed while the 0-360 graduation is moving. I need, like in a compass, a fixed graduation and a moving needle.
For example this seems fine to me but I have no idea what instrument is:
