Meet the Barman II: a mixing platform that relies on Bluetooth 4.0 to connect to your smartphone. This open-source device is compatible with iOS and Android devices. It tells you how much of what to pour. The progress indicator lets you know how much you have left to pour.
The Barman II has a backlit LCD, 2 CREE glass-illumination LEDs , and a water-resistant tempered glass surface. It has a range of up to 50 feet and runs on AAA batteries. It has a 64-ounce drink capacity. The companion app lets you load drink recipes, customize them, and learn how to prepare new ones. More information is available on Kickstarter.
