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.
The most rewarding part of any project must be sitting down to see the fruits of your labors set in action for the first time and relaxing with a nice drink. [Tony DiCola] is really showing off his ability to think ahead, because his smart cocktail shaker takes care of the post-build celebration, measuring out drinks with exacting precision.
The build measures out precise amounts of any liquid with the help of a small electronic scale [Tony] picked up from Harbor Freight. Instead of trying to interface with the electronics in the scale, he instead connected a INA125 instrument amplifier to the load cell. An Arduino micro measures the weight on the load cell, and with the known densities of gin, vermouth, and Kahlua, [Tony] can get a very good idea of how much liquid is in the cocktail shaker.
The really neat part of this build is the interface: [Tony] wrote an Android app for his tablet that talks to the Arduino with an Adafruit Bluefruit Bluetooth adapter. The app receives the current weight on the load cell, displays the current amount of liquor in the cocktail shaker, and provides step-by-step instructions for making any cocktail.
It’s a handy little device to keep around the liquor cabinet, and with an absurd amount of pumps and valves could easily become the basis for a very cool cocktail bot.

Having an open bar usually means hiring at least one bar tender. But this hack does away with those labor costs (and someone to make sure your teenage cousins aren’t drinking) by putting a robot in charge of things. But the fun doesn’t stop there. One of the features of this bartender is that it records a 30 second video every time it dispenses a beverage. We’d image these get a bit funny as the night wears on before taking a dramatic turn into sadness.
The link above shares a ton of details on the device so make sure that you click-through the different pages in the navigation bar. The mechanical page shows off all of the effort that went into designing the machine in Solidworks. The ingredients start on the top layer in inverted bottles. Each feeds to a valve which has its own nozzle. Like a round version of the Inebriator, a glass is placed in a trolley at the bottom that pivots around the center of the machine. Once it gets back to the opening in the acrylic case you can grab your drink, give it a quick stir, and off you go.
Check out the video after the break to get a look at the user interface which includes that recorded video greeting for the happy couple.

The staff of Instructables know how to cut loose and cool off in this already-too-hot summer. They’re making their own popsicles out of cocktails. If only everyone were lucky enough to have employers who endorse these kinds of projects at work.
So the problem here is the the freezing point of liquor. Your margarita, daiquiri, strawberry with champagne, white russian and other favorites just aren’t ever going to solidify in a run-of-the-mill freezer because zero degrees Fahrenheit just won’t cut it. So the big guns were brought to bear. The cocktail-pops were lined up in a container and dowsed with liquid nitrogen.
The substance boils off at around -321 F, more than cold enough to quickly freeze these alcoholic goodies. But use caution. After they’ve been frozen you need to throw them in the freezer to warm them up. The first guinea pigs burned their tongues when trying to lick the pops too soon.
Don’t want to buy your liquid nitrogen? Why not just make your own?
Want some fancy ice for your next cocktail party? You can try to find spherical ice-cube trays but you won’t get the kind of results seen here. It turns out the trick to this isn’t how you freeze the water, it’s how you melt the ice.
[Brendan O’Connor] started this project after seeing an ice mold that could make beautiful shapes rather than just cubes. But the price tag was $1400. If he could make his own at a hackerspace we’d bet that would pay his membership for an entire year!
The concept is pretty simple. The video after the break shows the mold he was trying to recreate. It’s two hunks of metal with a shape milled into them. The mold is pre-heated, then an oversized hunk of ice is placed between the blocks. The heat melts away the parts you don’t want, and leaves a perfectly shaped ice orb in between. Gravity is responsible for pulling the mold halves together as they slide along some machined rods.
With a big hunk of scrap aluminum he milled two halves of a sphere. They can be sufficiently heated if held under running water, and a some leftover printer rails keep the two parts aligned as the ice orb is formed. Now [Brendan] just needs to work on his method of creating a crystal-clear ice block as a starter and he’ll have achieved total win.

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!
