Christmas is coming, which is a good excuse to gather socially and drink fermented vegetable products. And what better way than via this Arduino-powered cocktail dispenser, which features a rotary encoder for navigating the cocktail menu, a TFT screen, laser-cut plywood and plastic body, and an Archimedes screw to give your beverage just the right amount of ice. It’s brilliant: so brilliant that we’ve asked Sven to tell us all about how he built it in the next issue of HackSpace.
