In order to get a margarita just right, the various ingredients need to be mixed together quite vigorously to over-come the different viscosity of the fluids. Looking to create his own barbot of sorts, [TVMiller] decided to make a Margarita Drip Infuser to help make margaritas a bit easier.
Using various chem lab supplies, [TVMiller] has cobbled together something pretty awesome. The Infuser can take up to 8 different ingredients into its test tube reserves, and after the drink ingredients are programmed on the computer, the magic begins.
An Arduino Uno controls a bank of 8 relays which control small fluid solenoids, with each control pulse releasing just a single droplet of fluid. An LED for each valve is run in parallel adding a bit of a light show to the mixing experience. If that’s not enough, he’s also created a copper cooling coil to chill the drink as it is poured.

Ever feel the need to have your very own alcohol vending machine at home? Well if you do, [Ben] and [Dan] have just the Arduino based machine for you!
It was actually part of a school assignment for product design at Brunel University – the whole thing was designed and built in just over a week. The machine accepts and counts coins giving you a total readout on the LCD screen. When the correct amount is inserted you can select your shot and the machine will pour you a stiff one.
The thing we like about this vending machine — we’re not sure if it actually qualifies as a barbot — is that it doesn’t have any fancy pumps. In fact, it just uses two inexpensive solenoid valves and gravity to dispense the drink, much like a typical bar bottle dispenser.

It’s been a rough day at the office. You need a break. But by yourself? No, what you need is to be Synergized! This Barbot only works if all four keys are inserted and turned — kind of like a nuclear launch procedure — only then will it dispense four perfectly sized drinks to make your day better.
The Synergizer uses an Arduino to control a belt driven linear actuator which moves the spout from cup to cup. A series of reed switches along the length provide feedback to the system for positional control. The machine makes use of a peristaltic pump, called the Bartendro Dispenser, which pumps an exact volume of your liquid of choice into each cup. The cool thing with peristaltic pumps is they are self priming,and capable of pumping an exact volume of liquid every time.
[Nick Poole], the designer, also included a CPU fan and heat-sink paired up with a peltier plate in order to also chill the liquid as it is being pumped. To make it even more interesting, he added a four key override, so the Synergizer can only be used if all four unique keys are inserted.

Oh for the day when we can stop repeatedly looking up our favorite drink recipes on Wikipedia. Those may be just around the corner and you’ll have your choice of single-click delivery or toiling away in the workshop for a scratch build. That’s because Barobot is satisfying both the consumer market and our thirst for open hardware goodness. They’re running a Kickstarter but to our delight, the software and mechanical design files are already posted. Before you dig into the design files there’s a really good look at the constituent parts in the assembly manual (PDF) — that’s a lot of pieces! — and a tiny bit on the tech-stuff page.
This remind us of the Drinkmo we saw earlier in the year. That one cames complete with the high-pitched whine of stepper motors. We didn’t get to hear Barobot’s ambient noise in the promo vid after the break. But one place this desing really shines is a swiveling caddy that allows for a double-row of bottles in a similar footprint. One thing we’d be interesting in finding out is the cleaning procedure. If anyone know what goes into cleaning something like this let us know in the comments.

We’ve seen BarBots that will automagically pour you a drink, but how about one with RFID? How about one with Facebook integration, so your friends know how much of a lush you are? Wait. Facebook already tells them that. Huh.
[Andy] and [Daniel]’s latest build follows on the heels of a lot of similar cocktail bots; an Arduino controls a few solenoid valves connected to a CO2 supply and a few bottles of liquor and mixers that allow drinks to be dispensed at the push of the button. Where this project gets interesting is its use of RFID and Facebook.
The user interface was coded for Windows 7, with an RFID tag (ostensibly issued to each guest) allowing a unique login that checks an SQL server to see what privileges the user has. The app pulls the user’s Facebook profile photo down and displays it in the corner of the screen, and with the server keeping track of how many drinks (and of what kind) they had, with the right permissions it should be possible to post that info to their wall. Because we all know what you did last night, even if you don’t.
[Cabe Atwell’s] latest project is a work of art. Let us introduce the Drinkmotizer: a Raspberry Pi Drink Mixing Robot.
As [Cabe] says, almost every engineer has a drink-mixing robot on their project todo list. We’d probably have to agree; they’re functional, cool, and useful at parties.
You need the Drinkmotizer at your party… At some point, dexterity for drink mixing is lost at a gathering.
Drinkmo is your designated, sober, mixologist.
Drinkmo works by rotating a long leadscrew that moves the mixing glass from bottle to bottle. The entire setup is made using aluminum extrusion, and is by nature, completely expandable. On the top shelf are gravity fed shot dispensers, controlled by 12VDC car lock actuators. The chaser station (at the end, on the right) works differently. The chaser bottle is actually pressurized by a paintball gun tank and dispensed using a solenoid valve. We hope he’s got a pressure regulator in there, considering the pressure capacity of paintball tanks can range from anywhere from 1000-3000PSI!
The entire system is controlled by a Raspberry Pi running Raspbian, and [Cabe] is using Tkinter for the GUI of the program. He’s got tons of info on the original forum post linked above (including the schematic!), and if you stick around after the break, there’s a very well produced video of Drinkmo in all its glory.

Are you good at mixing drinks? We think this Barbot might give you a run for your money!
Not only does this Barbot have room for 5 different liquors, but you can combine them any way you want with an extremely slick web interface that you can check out for yourself.
During initial setup, you add your chosen liquors to the machine and then using the configure mode in the web interface, you tell Barbot what it has to work with. Once these fields are populated, Barbot will list various drinks that it is capable of mixing with the provided ingredients. It also has a cleaning mode, which allows you to prime the pumps and set administrative access for your parties.
The hardware behind this build is a BeagleBone Black running Ubuntu 13.04 with Apache2, MySQL, and PHP to host the web interface — bind and DHCP are used to create the web portal using a USB WiFi dongle. The online interface directly controls the pumps using PHP via the GPIOs.
To see a full demonstration stick around after the break for the included video.
