great idea / technology, lame page. Would love to see a decent article on the topic, with specifications about the minimal number of components to do something useful (enough to use the input jeck ADC in a decent way), and some example application that you can actual build easily with schematics. IMHO a good show case could be a termometer that you can plug to your iphone with minimal components, using a classic temperature sensor that changes the resistance with difference of temperature.
