This drink machine pours, slices, and dispenses mint!
Automated cocktail machines can be fun projects, but this device by CamdenS5 takes things to a whole new level. Not only can it pour liquids from multiple bottles, but it chops limes, dispenses sugar and mint, and even features a refrigerated compartment to keep ingredients at the appropriate temperature.
There’s a lot going on mechanically inside, including a linear actuator for chopping, and augers that dole out mint/sugar as needed.
Details on the build are available here, with code/files ready for download, and an interactive Fusion 360 model that you can manipulate in your browser.
