Speedy Drinkmaker Keeps Party Guests Hydrated

August 20, 2014 by Bryan Cockfield 23 Comments

After five weekends of work, [Alex] completed his automatic drink maker, the RumBot. What makes this automated bartender different from others is the fact that it is fast. VERY fast. It can serve drinks to five different locations in as little as 3 seconds per drink. By [Alex]’s estimation, this could keep a party of 100 people going without anyone waiting on a drink.

The RumBot can make either of five pre-programmed drinks at varying levels of alcoholic intensity, ranging from 1 (“Virgin”) to 10. And for that extra push over the cliff, you can turn the knob to 11 (“Problem”).

Drink 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. It houses a very robust servo on a ~~belt~~ screw-driven stage to move the drink nozzle, and special sensors placed at either of the five drink locations detect a cup ready to be filled. Any cup placed at any of the positions will automatically be filled based on the RumBot’s settings at any particular time.

Based on the quality of the build and the increased speed of this automatic drink maker, this should be a huge hit at any party. With all the knobs turned to 11 though, it might be a good idea to have a breathalyzer on hand! All of the code and schematics for the project are available at the project site as well.

R2D2 Drink Dispenser Will Happily Tinkle In Your Glass

August 16, 2012 by Mike Szczys 8 Comments

As with Jabba the Hutt we’d like to have our own service droid to serve up a cold one. We’re in luck; it looks like you can make your very own beverage dispensing droid if you don’t mind a little awkward dispensation.

The body started as one of those big protein drink mix containers. After spraying it white and masking off the entire thing with blue painter’s tape, the shapes for the blue designs were cut out and painted. Half of a foam sphere from the hobby shop was used to form the dome.

Liquids are dispensed by the pump system from a Super Soaker motorized water gun. You can see it fill up a beaker with a mysterious blue liquid in the video after the break. It’s a long way from challenging the Bar2D2, but it’s also something a mere mortal can build

Any Flavor Sports Drink At The Push Of A Button

July 13, 2012 by Mike Szczys 22 Comments

[Sage Spate] wasn’t happy with the boring flavors of orange, blue, or red sports drinks. He decided to mix it up by building this flavor-mixing drink dispenser.

He modified the caps for each bottle to work with an air-pressure system. This way the bottles themselves serve as the reservoir and can easily be replaced when empty. Each cap has two openings, one is used by the dispenser nozzle and includes a hose that will reach all the way to the bottom of the bottle. The other hole connects to an air pump. Raising the pressure in the bottle forces sports drink up and out of the dispenser hose.

One air pump is used for all three reservoirs with a set of solenoids to enable each flavor individually. [Andreas] sent in the tip and mentioned that some of the parts are salvaged from an ink jet printer but we’re not sure which ones. At any rate, the next step in the project is to add Arduino control which will allow for custom mixing based on preset recipes.

We’ve embedded the demo video after the break.

Cocktail Machine Minces Words

September 30, 2011 by Mike Szczys 10 Comments

For those living in a magical land of candy, with orange-faced helpers to do their bidding, the ability to taste your words is nothing new. But for the rest of us, the ability to taste what you type in cocktail form is a novelty. [Morskoiboy] took some back-of-the-envelope ideas and made them into a real device that uses syringes as keys, and facilitates the injection of twenty-six different flavorings into a baseline liquid. He figures that you can make each letter as creative as you want to, like representing different alcohols with a letter (T for tequila) or matching them to colors (R for red). Check out the video after the break to see an ‘Any Word’ cocktail being mixed.

This setup is entirely mechanical, and makes us wonder if [Morskoiboy] works in the medical equipment design industry. Each letter for the keyboard is affixed to the plunger on a syringe. When depressed, they cause the liquid in an external vessel (not seen above) to travel through tubing until it fills the proper cavities on a 15-segment display to match the letter pressed. From there the additive is flushed out by the gravity-fed base liquid into the drinking glass. We can’t imagine the time that went into designing all of the plumbing!

Perfect Shots Every Time

December 28, 2010 by Caleb Kraft 23 Comments

A shot is a shot right? Well, not really. Usually we see a sloppy shot poured of a single type of alcohol and, depending on our current standing with the bartender, may or may not be full to the brim. The Pousse-Cafe makes an art out of your drinks by perfectly layering several liqueurs. Not only will it measure them out perfectly, but it is voice controlled as well. There are 3 liqueurs to choose from, as they were going for a specific, visually appealing drink (otherwise, why bother?). Judging from the pictures it looks like it’s using an arduino in conjunction with a laptop for control.

You can see a video of it in action after the break.

NYC Resistor Takes On The Machine

October 7, 2010 by Jakob Griffith 3 Comments

Here we are with Episodes two and three (aka, NYC Resistor part one and two) completing the Take on the Machine Hackerspace challenge we mentioned a while back. For the challenge NYC Resistor took an old style slot machine and converted it into a drink mixing deviant; even making the device post a Tweet for every drink. However, it seems to be lacking refrigeration of some kind, could this be the downfall of a potential winner for the challenge? Up next is the Hackerspace Pumping Station: One: do you think they can compete? Is there a particular Hackerspace you can’t wait to see? Let us know!

[Thanks Deven]

Don’t Worry Occifer, There Is No Blood In My Alcohol!

[Daniel] wrote up a quick tutorial on interfacing with the MQ-3, or better known Breathalyzer from SparkFun with Arduino. While we would have used perhaps an op-amp/comparator based system and kept it in a much smaller package, the idea was so quick and simple and enjoyable we hoped an article might keep some hackers from drinking and driving.
