Diy BrainPort device Answered
These brainport things look cool. Basically they use your highly-sensitive tounge nerves to feed data into your brain. Totally safe and non-invasive, they can even allow blind people to see, which is, of course, amazing.
I'd like one for fiddling with (eg, monitorless computer? what kind of other data can you feed into your brain? Other stuff??) But since the gizmos are like ten grand apiece... not likely!
Then again, its just an array of contacts that deliver 5-20v at low amps so how hard could it be? Thoughts? Links? Circuit ideas?
