A pretty sweet step towards full man-machine integration, Melon Brain Monitor is a headband-and-app combo that essentially acts as a mini-EEG, with sensors, embedded in the comfortable, neoprene-lined silicone band, that measure activity in your pre-frontal cortex, letting you track your focus on whatever activity you choose to check. Example: You’re studying calculus and you crank up some death metal…how’s your focus working for you now? The the self-tuning possibilities are endless! Funding on Kickstarter now. Special preorder price: $79.
