iZac doesn't want to hear your sob stories. No, this Arduino-crafted bartender just wants to make cocktails, ordered through a tablet-based drinks menu. The bar patron can then place a glass on the digital scales, and iZac will measure out in the prescribed quantities necessary for the meatsack's choice of poison. The liquids are handled by aquarium pumps and laser-cut pinch valves, with accuracy to within one gram (0.035 ounces). Sadly, the bar bot's repertoire is limited by six bottles, arranged on two turntables. Risky drinkers can plump for the 'I'm Feeling Lucky' option, which creates a randomized drink of three (possibly identical) liquids. See how it all comes together in a loud, appropriately shady-looking bar after the break.
