The thread for my tricorder simulator is here:

It is true that it is just for 'entertainment' purposes, but I tried to add as much 'useful' functionality as I could to the simulation e.g. bluetooth GPS position, weather data download from Yahoo, weather map/terrain data downloads.

Yes, it would be great if some other miniature (USB-based?) sensors could be attached i.e. pan/tilt/accelerometer sensors, digital thermometer/pressure/humidty sensors, light sensors (doesn't the N810 have that?), etc.. As has been mentioned, though, the actual 'user interface' for the Star Trek 'tricorder' is poor and wasteful.
