So, I heard about this NeuroSky chip that reads some raw EEG to determine focus level, and it got me thinking about an efficient, hands-free MP3 system.
See, I'm a geek and I'm big into over-the-ear headphones. I don't care how clunky they are, they don't violate my earholes and they give good sound quality no matter how cheap they are, for the most part.
So I had this idea- If I could put a NeuroSky chip to read attention levels, an Arduino Nano, and some sort of playback device, I could build it straight into the headband. From there, it's just a matter of giving it something to play and having it play it. Whenever someone got my attention, it could automatically turn the sound down, even stop the song, so I could hear what they're saying, then chillax and the volume would go straight back up.
I'm thinking about accomplishing this by means of a wireless remote I can keep in my pocket (maybe add a "shake to skip song" feature) That would serve to store the songs via SD card or maybe USB. This would be a second Arduino, with buttons and a transceiver, probably in a painted mint tin.
So here's my actual questions:
Playback- Ouch. I've never dealt with anything like this; I'm a newbie and I may have bit off more than I can chew with this bit. How do I read/write from SD or flash drives? Playback needs to output to headphone jack, what kind of stuff am I looking at?
There's also a telemetry issue, something else I'm new to. I'm sort of new to everything.
What would you recommend for cost efficient streaming-audio and two-sided communication that could fit in a headband? Keep in mind, this is just pocket-to-head, but it needs to be seamless. Weight is probably the biggest concern, this, the Nano, and the NeuroSky chip need to fit smoothly into the headband.
EDIT: Oh, power. Power considerations. I could use some wisdom here too.
