As it turns out, the military is less interested in frying people's brains and more interested in reading their thoughts. A newly-unearthed DARPA grant competition from this spring shows the military construct's goal: the development of a cheap mind-reading headset which can feed EEG data from its wearer to a smartphone app.
EEG readings are the basis for a number of consumer products which allow users to control objects with their minds. Thinker Thing, for instance, lets its user imagine and then 3D print creatures straight out of their imagination. But that's not exactly a military application of the tech.
