This is the first test of a wearable tech concept. As pointed out by some nice people at OMG (Omaha Maker Group.. it was actually David there who suggested I try out sensory augmentation, awesome idea :) ) it is more than just a toy and possible tool for the deaf, with so many people tuned out wearing headphones.. it might actually be useful to hearing-able people too hehe ;)

Just six mics mounted in the 6 air holes of the hat (would work better if the were at the base of the hat but there are already holes there so I just used them for now.. results not too bad).

The 6 signals are first balanced relative to each other, and then the six leds are controlled corresponding to the relative amplitude of each respective mic.

I originally planned to make a circle of leds on the underside of the lid, but that seemed too hard to read. I found that if you place the LEDs well you can actually make the rear 2 microphone LEDs feel somewhat behind you in your peripheral vision so a semicircle curve on the lid rim can actually almost feel like a closed in circle... it almost feels as though you can "see behind you")

Kinda wanna try it with ARM,Camera and opencv. but with the camera moving around so wildly i doubt it will be very easy.. would be cool to be able to "see motion behind you".. but unfortunately that’s gonna be really hard.. (unless i can strap the persons head to a lamppost or something lol)
