A Nano scaled speedometer…..

Well yesterday night i was talking to my friend adu … and we somehow managed to stumble upon a awesome project .. for starters we named it the “next nano thing” .. it actually is something based on my ipod touch technology … Well the ipohone/ipod touch conatins a 3-d axis accelorometer .. what is does is give relative accelaration relative to the objects frame of refrence .. but what it fails to do is give the velocity of the object realtive to a particular frame of reference  ( the standard can be taken to be earth’s f.o.r). Well as i was saying to adu .. what you can do is somehow amplify the signals genrated from the bluetooth .. and install a wavelength mesaurer in your device .. then depending on the strength of the signal ( dist travelled ) you can mesaure your given velocity according to the doppler’s shift in wavelength due to velocity …  bluetooth wavelength arent high powerd and most signal will be lost .. so what we wanna do is amplify the signals .. and still be able to minitarise it .. seems pretty cool .. doesn’t it ?
