Thinking about anemometers with no moving parts- it may be possible to use a cheap pressure sensor as a pitot tube, with a 360 degree cowling that funnels horizontal moving air upwards into the sensor (picture two smooth funnels inserted into each other). An apparently cheap & suitable sensor for Arduino is: http://www.coolcomponents.co.uk/catalog/product_info.php?cPath=36_68&products_id=739 Coupled with a GPS chip to get SOG & COG, apparent and real wind speed could be directly output in NMEA0183 format. Add wind direction and done.
Pricey, but likely very useful: http://www.liquidware.com/shop/show/TSL/TouchShield+Slide
And the 4D http://www.youtube.com/watch?v=Z-Cf681Qurw&feature=related available here (they also have an air pressure sensor): http://www.coolcomponents.co.uk/catalog/product_info.php?cPath=45_72&products_id=676
With a GPS sensor, can get time & speed, with the speed and wind direction & wind speed, should be able to output real wind & apparent wind speeds and direction from the single anemometer sensor already mounted.
This guy has a lot of info: https://sites.google.com/site/vilorei/index/arduino—serialgpsunit
Another possibility is hacking an Archos 5 or 7, since they run linux it should be possible to code normal apps for display- the issue is input, there's only one serial port, so some kind of NMEA multiplexer & converter to ethernet or USB might be better. They come with GPS and accelerometers and all kinds of capabilities built-in.
There's also Android based hardware, http://antipastohw.blogspot.com/
Maybe a pitot tube can work accurately from 360 degrees? See below:
not suitable, but a good site: http://shop.moderndevice.com/products/wind-sensor
Another thought- light-sensing for wind speed & direction? In that case no POT or essentially any connection to moving parts would be necessary. The moving parts would simply need to be free to move, and “reading” them would be a matter of sensors. Maybe CDS's to sense the position of the vane and the flashes of anemometer cups moving by? A single white LED could be used for constant illumination.
