What about attitude and heading?


You know how electrical engineers are. They drool over the thought of
making a gadget that is compatible with an interface like USB. If it
can be done, someone is probably doing it.

altitude
velocity (translational and rotational)
acceleration (translational and rotational)
humidity
windspeed
attitude
temperature
pressure
GPS coordinates
illumination
etc....

All they do is take the existing devices, throw on USB interface, and
and it's good to go (and cheaper).
