Melon

"Know thyself" isn't just an ancient aphorism or something cool written above the Oracle's door — it's sound advice. Melon ($100) is a new gadget that aims to help you on this quest by measuring your ability to focus. It does this via a wireless headband that uses EEG to measure brain activity, and an app that uses this information to monitor your focus, letting you tag each session with the activity you were doing, environment, behavior, and more. It also doesn't look too ridiculous — it comes in black or white — and is expected to ship in November. [Scouted by Ryan]
