Powering Nano without blowing off my head?

If you are going to put this on your head I would strongly recommend not building it yourself, and buying something from a reputable source.

Google “electronic cigarette explosion” or “rc battery explosions” and you will understand why...

Yikes... And with that, I'm thinking I might just run a the wires from the eye, around the strap and down to my back where I can use 4 AA batteries and a voltage regulator circuit.
