Meet the MixStik: a smart stick that connects to your smartphone via Bluetooth to show you how to mix drinks like a pro. You will just have to choose what you want to prepare in the app, and MixStik will use multi-color LEDs to guide you. The device has a rechargeable battery.
MixStik has 24 LEDs and motion sensors, so you can do much more with it. There is also a SDK for developers. The product will be on Kickstarter soon.
