So you want to make a selection of drinks, but you need to know what to put in a how much. This device works with an app. You selected the drink that you want, it will tell you when to stop pouring each measurement. Its meant to make drinks just like pro barmen. So if your picky about how your drinks taste, then this is for you.
This project is currently on Kickstarter so if you want to fund it the link is here: http://www.kickstarter.com/projects/781775326/the-barman?ref=category
