News: Brain Hacking and Thought-Controlled Quadcopters: The Good and Bad Future of Mind-Reading Devices
Until recently, brainwave-reading devices have pretty much only existed in science fiction. Sure, electroencephalography (EEG), the technology that powers these devices, has been used in medicine and psychiatry since the late 1800s, but diagnosing people's brains and reading their minds are two totally different things. The first EEG headsets available to the public were used mostly in gaming and even in fashion, but in the last few years, they've gotten a little more sophisticated.

How To: DIY Flanagan Neurophone Lets You 'Hear' Sounds Through Your Skin
In 1958, Patrick Flanagan invented the Neurophone, a device patented in 1962 that allows radio signals to be picked up by the human nervous system. The skin is the organ that receives the signal, converting it into a modulated molecular vibration, which the brain interprets into sound. Basically, it gives one the ability to 'hear' through the skin, making it sound like the audio you're hearing is actually in your head. It's kind of like having headphones in your brain. The only problem was th...
