Cool Windows Phone 8 Bluetooth API Demo–Connect to your EEG Reader!
Windows Phone 8 now has an open Bluetooth API, which means developers can get really creative.
Probably the coolest demo so far is the above app by Justin Angel, which lets a user connect to the Mindwave Mobile Headset and literally read your mind, or at least the waves it generates.
Justin has also packages the components of the app into an open source SDK for connecting to the headset, which he calls MetroEEG, which can presumably be adapted by developers for all kinds of other Bluetooth gadgets, including for example Bluetooth Blood Sugar glucometers.
