This Arduino-powered machine turns tweets into cocktails

Who knew you could get drunk on data? 

You’ve most likely read a tweet, you’ve probably even heard a tweet aloud, but chances are you’ve never tasted a tweet. But that may all soon change, because Clément Gault and Koi Koi Design have developed Data Cocktail, an Arduino-powered machine that whips up cocktails based on, you guessed it, Twitter activity.


Data Cocktail works by scouring the web for the five latest posts mentioning keywords that are linked to available ingredients, represented by differently colored bulbs. (The system will accept either words, hashtags and mentions.) These messages are then used to define the composition of the drink and fill the glass accordingly. The result is an original, crowdsourced concoction whose recipe can be printed out.

“If you’re wondering whether a tweet about Santa Claus in Winnipeg, Canada can take part in generating a cocktail in Nantes, we say yes! Data Cocktail is a machine but it doesn’t exclude a minimum of politeness,” its creators reveal. “Once the cocktail mix is realized, Data Cocktail will thank the tweeters who have, without knowing it, helped at realizing it.”


Its creators reveal that they can easily change the keywords, ingredients and proportions to suit specific events. Meaning, the robotic bartender can make drinks based on everything from election coverage (whether you’re experiencing a Trumpertantrum or feeling the Bern) to what’s trending at any particular moment.

In terms of software, Data Cocktail uses the Processing and Arduino programming languages. A first application, developed in Processing, pilots the device. The requests are performed using the Twitter4J library, while the app processes the data and commands the robotic gadget.


As for its electronics, Data Cocktail is comprised of a robot, solenoid valves and LEDs. The robot is built around a modified Pololu Zumo chassis with a motor shield, a Bluetooth module and an Arduino Pro (ATmega328). Meanwhile, the valves and lights are controlled by an Arduino Due (SAM3X8E) connected via USB.

An Internet-connected, voice-controlled robotic bartender

One Maker has built his own Internet-connected, voice-controlled robotic bartender with Arduino. 

If you enjoy mixed drinks, but would rather not have to think about mixing them correctly, a robotic assistant could be quite helpful. Tony Marsico has had a vision of this kind of assistant since he got out of college, and finally got around to building it as his first Arduino-based project.


After some initial testing of how his peristaltic pumps worked on an Uno (ATmega328), Marsico attached five of them to a wooden frame, as well as an Aduino Yún (ATmega32U4) to control everything. A transistor array switched by outputs from Yún the drives the pumps.

The Yún is a little more expensive than some of the other Atmel-based boards on the market, but its built-in Wi-Fi capability made it quite conducive to connecting the device to the Internet. To allow for voice control, he used an Amazon Echo. This control scheme explained around 1:20 in the video below with a nice whitboard illustration. As he puts it, his device is an “Arduino-powered, voice-controlled, Internet-connected, electronic bartender.”


Possible future upgrades include an expanded ingredient capacity, as well as a website for the device that would include a BAC (blood alcohol content) leaderboard. This kind of information could be useful as an estimate, but it’s unlikely that a police officer would listen to any excuse involving the words, “My robot said it was OK.” Seriously, please robo-drink (and normal drink) responsibly!

Bartesian makes cocktails from capsules in seconds

This Keurig-like machine will mix the perfect cocktail with the press of a button.

Generally speaking, creating more than the simplest mixed drink at home requires several ingredients along with a little bartender know-how. Fortunately, one Waterloo, Ontario startup has developed an automated solution to that problem. Like a Keurig for cocktails, the Bartesian is a capsule-based machine that enables anyone to expertly make their favorite summer alcoholic beverages in a matter of seconds with just the press of a button.


The next-generational kitchen appliance works by inserting a pod and selecting the strength of the drink (from light to heavy pours). From there, the robotic bartender will whip up the perfect amalgamation every time. What’s nice is that, instead of having to stock up on different liqueurs, bitters and juices, the Bartesian packs all of those flavors into one tiny capsule. A user must still supply the booze, of course.

The machine is equipped with four little glass reservoirs that can be filled with any of the basic spirits, namely vodka, gin, tequila and whiskey, which are then used to craft drinks based on the recipes associated with each pod. This is made possible through an intelligent barcode system that automatically reads the ingredients for the chosen cocktail and begins preparing it to one’s liking.


The team has launched six of their favorite blends for its Kickstarter campaign — including classics like Margarita, Sex on the Beach and Cosmopolitan and three signatures — with plenty more to come in the near future. A la carte selections, themed packs and seasonal varieties are also among some of the options that will become available.

Built around an ATmega2560 MCU, the electronics are all housed inside a sleek metal enclosure with stainless steel accents. The Bartesian features an ultra-simple, three button interface that lets users pick the drink, choose its strength and start the process.


Similar to many other startups these days, its inventors Bryan Fedorak and Jason Neevel decided to head to Shenzhen to finalize the product’s design and set up its supply chain, all under the guidance of HAXLR8R — one of the world’s leading hardware accelerators. And now, the crew is ready for mass production.

Sound like a device you’d love to have for your next Friday night party or Saturday afternoon BBQ? Although the team recently completed their successful Kickstarter campaign, Bartestian is still available for pre-order on its website here. Delivery is expected to get underway in April 2016.

Arduino-Powered Bartender Takes Orders Via Facebook, Twitter

How’s this for the life of the party? A robotic bartender, powered by Arduino and connected to Facebook and Twitter. Use a Facebook app, or a Twitter bot, to order your cocktail from the Social Drink Machine. And use the same app to tell your friends what you just ordered!

The creativity that fuelds the Arduino community is always impressive. And so are the underlying megaAVR microcontrollers inside the Arduino boards. Low-power, highly integrated megaAVR devices support the fast development process that enables designers to take fun and quirky ideas and quickly turn them into working products.
