And for that extra push over the cliff, you can turn the knob to 11 (“Problem”).ĭrink selection itself is handled by a simple digital I/O on an Arduino with a 1950s-styled user interface. The frame is built out of wood and uses 3D Printed plastic parts. The RumBot can make either of five pre-programmed drinks at varying levels of alcoholic intensity, ranging from 1 (“Virgin”) to 10.

By ’s estimation, this could keep a party of 100 people going without anyone waiting on a drink. It can serve drinks to five different locations in as little as 3 seconds per drink.

What makes this automated bartender different from others is the fact that it is fast. Check out his build and the pump in action in the video below.Ĭontinue reading “Cocktail Machine Mixes Perfect Drinks Every Time” → Posted in cooking hacks Tagged arduino, drink dispenser, drink mixing robot, load cell, peristaltic pumpĪfter five weekends of work, completed his automatic drink maker, the RumBot. The result is a machine that’s sure to be a centerpiece for any hacker-filled party. A simple calculation based on the pump’s quantity per second and the desired quantity tells it how long to leave the pump on for. After the machine turns a pump on, a load cell located under the glass tells it when liquid has started arriving at the glass. How does the machine know when to stop pumping a certain liquid? Each pump is rated for a specific quantity per second, though he tests this for each liquid anyway and finds a slight variation which he accounts for in the code.

Using a knob and LCD screen, you can enter any quantity you want for the three liquids, though you’ll have to edit the Arduino code if you want to change the liquids’ names. In typical style, while he tears apart the pumps to replace the tubes, he gives us a good glimpse of just how they work. The machine can mix three different liquids and does so using three peristaltic pumps. But don’t be fooled - it may look crude on the surface, and vibrate a bit while working, but the mechanism is plenty sound and functional. has come up with a solution, what he calls a crude cocktail mixing machine.

the holiday season is coming up and that means hosting parties and mixing drinks, which can get tiresome.
