It’s often taken for grated, but the modern world is full of luxuries. Home automation, grocery delivery, and even access to the Internet are great tools to have at hand, but are trivial to most of us. If these modern wonders are not enough for you, and the lap of luxury is still missing a certain je ne sais quoi, allow us to introduce you to the ultimate convenience: a voice controlled, beer-dispensing sofa with a built-in refrigeration system.

This is a project from [Garage Avenger] and went through a number of iterations before reaching this level of polish. Metal work on the first version didn’t fit together as expected, and there were many attempts at actual refrigeration before settling on repurposing an actual refrigerator. With those things out of the way, he was able to get to the meat of a project. The couch-refrigerator holds 12 beers, and they are on a conveyor belt which automatically places the next beer onto the automated drawer. When commanded (by voice, app, or remote) the sofa opens the drawer so the occupant can grab one easily without having to move more than an arm. Everything, including the voice recognition module, is controlled by an Arduino, as is tradition.

The attention to detail is excellent as well. The remote control contains a built-in bottle opener, for one, there are backlights and a glass cover for the refrigerator, and the drawer is retracted automatically when it senses the beer has been obtained. We couldn’t ask for much more from our own couches, except maybe that they take us where we want to go. But maybe it’s best to keep these two couch use cases separate for now.

Usually, when we are talking about homebrew around here, we mean building your own equipment. However, most other people probably mean brewing beer, something that’s become increasingly popular as one goes from microbreweries to home kitchen breweries. People have been making beer for centuries so you can imagine it doesn’t take sophisticated equipment, but a little automation can go a long way to making it easier. When [LeapingLamb] made a batch using only a cooler, a stock pot, and a propane burner, he knew he had to do something better. That’s how Brew|LOGIC was born.

There are many ways to make beer, but Brew|LOGIC focuses on a single vessel process and [LeapingLamb] mentions that the system is akin to a sous vide cooker, keeping the contents of the pot at a specific temperature.

Honestly, though, we think he’s selling himself a bit short. The system has a remote application for control and is well-constructed. This isn’t just a temperature controller thrown into a pot. There’s also a pump for recirculation.

The common stock pot gets some serious modifications to hold the heating element and temperature probe. It also gets some spring-loaded clamps to hold the lid down. Expect to do a lot of drilling.

The electronics uses an Arduino, a Bluetooth board, and some relays (including a solid state relay). The finished system can brew between 5 and 15 gallons of beer at a time. While the system seems pretty good to us, he did list some ideas he has for future expansion, including valves, sensors for water level and specific gravity, and some software changes.

After reading that the system was similar to a sous vide cooker, we wondered if you could use a standard one. Turns out, you can. If you want to make better beer without electronic hacking, there’s always the genetic kind.

What’s better than an ordinary end table? How about an end table that can serve you beer? [Sam] had this exact idea and used his skills to make it a reality. The first step of the build was to acquire an end table that was big enough to hold all of the components for a functional kegerator. This proved to be a bit tricky, but [Sam] got lucky and scored a proper end table from a garage sale for only $5.00.

Next, [Sam] used bathroom sealant to seal up all of the cracks in the end table. This step is important to keep the inside cold. Good insulation will keep the beer colder, while using less electricity. Next, a hole was cut into the top of the table for the draft tower.

The draft tower is mounted to a couple of drawer slides. This allows the tower to raise up and down, keeping it out of sight when you don’t want it. The tower raises and lowers using a simple pulley system. A thin, high strength rope is attached to the tower. The other end is attached to a spool and a small motor. The motor can wind or unwind the spool in order to raise and lower the tower.

The table houses an Arduino, which controls the motor via a homemade H bridge. The Arduino is hooked up to a temperature sensor and a small LCD screen. This way, the users can see how cold their beer will be before they drink it.

To actually keep the beer cold, [Sam] ripped apart a mini fridge. He moved the compressor and condenser coils to the new table. He had to bend the coils to fit, taking care not to kink them. Finally he threw in the small keg, co2 tank and regulator. The final product is a livingroom gem that provides beer on demand.

Demo video (which is going the wrong way) can be found after the break.

Creators Mike Wakerly and Eric Webb have been at the smart keg game for a while. The two originally sold Kegbot as a do-it-yourself open-source project. They realized there was a market for a little easier option, and developed the plug-and-play version they're currently raising money for on Kickstarter. We recently met up with the team to see the device in action. %Gallery-slideshow164837%

"There's something we miss when everything becomes virtual and goes online," says Tyler DeAngelo. "Tactile-ness gives it something that is more interesting and a deeper connection and makes it more meaningful." The ad executive invited us to Havas Worldwide's Chicago offices to show off his latest creation, and with Fifth Avenue Frogger, the Check 'N Chew Foursquare gumball machine and the Buzzed Buzzer under his belt, we took him up on the offer. His latest creation was born of the same desire to bridge the physical and the virtual. Created for a beer client, the bottle opener has Arduino Nano-based circuitry built-in, which connects with an Android handset via Bluetooth, sending texts to friends when you crack open a bottle.

"I'm definitely not the first person to say this, but creativity comes from finding meaningful relationships between things that already exist," explains DeAngelo. "Nothing I'm doing is going to change the world. A lot of the stuff I do is wasting people's time, but I still think that making someone think differently or making someone laugh or have fun -- wasting time is an important piece of innovation." It's also, naturally, an important part of engaging a public increasingly immune to sales pitches. Getting people's attention in an ad-saturated world requires a lot more than clever jingles. "i think the most innovative things in the media field should be happening inside ad agencies right now," DeAngelo adds. "If they're not, those who aren't innovating are going to be dead."

[Kerber] got his hands on a classic 1950′s General Electric fridge, and converted it into this classy vintage kegerator.

As his build log shows, it took an intensive restoration process to get this fridge back in shape. He completely stripped it down, scraping off the sixty year old insulation, fibreglass, and glue. Then the chassis was sanded down to a smooth finish and painted black. R-19 insulation was added to replace the old stuff.

Next up was electronics. An Arduino, DS18B20 temperature sensor, and a solid state relay were used to regulate the temperature and prevent frozen beer. There’s also a Guruplug server that reads data from the Arduino every minute. It makes this data accessible through a web page, so the temperature of the kegs can be monitored from anywhere. [Kerber] admits that this is overkill, but leaves room for future expansion.

The kegerator draws about 180 Watts, and runs for about 6 minutes per hour to keep the temperature regulated. This is pretty impressive considering the age of the fridge. The final restoration looks great, and serves up data along with the beer.

Do you know what you get if you combine 44 beer cans with an Arduino board and a Raspberry PI ? I tell you : fantastic user engagement!

It happened at Webstock, event which took place in Bucharest this month. Staropramen, one of the sponsors of the event asked us for an innovative way to offer a trip to Prague to one of the event’s guests.

So, we came up with a keyboard made out of 44 Staropramen beer cans. Each beer can was a key, and whenever someone touched it, the corresponding letter appeared on a large plasma screen (just like any regular computer keyboard).

And the surprise was fantastic! The user experience and engagement overcame any expectation. Every single person who attended Webstock tried the keyboard and participated to the contest.

Behind the scene, the system is built around an Arduino board and a few capacitive controllers (just like the ones which are inside smartphones’ touch screens), connected to a Raspberry PI board which controls the plasma screen display.

Other hardware we used was the Sparkfun MPR121 Capacitive Touch Sensor Breakout Board (4 of them, each controlling 11 beer cans) and one Sparkfun MP3 Trigger Board which controls the sound effects.

A movie and some photos took during the event can be found on the [website]
(feel free to use them if you want, or download directly the photos as a zip archive).

[Webstock] is the biggest blogging and social media event in Romania.

Are you bored with just drinking beer? Are your friends constantly sneaking into your house and stealing your sacred beverages? If so, perhaps you need KegDroid – the Android controlled beer tap created by [Paul Carff].

Looking for a way to add more excitement to drinking his beer, [Paul] spiced up his tap with a little extra technology. He added an Android tablet for touchscreen navigation of the menus, an Arduino to control the flow sensors and solenoid valves, and an NFC reader to act as security for restricted access.  Users must be authenticated before they are allowed to pour any alcohol.

Your name and photo are pulled from your Google+ account as you’re logged in, then you simply select your beverage of choice, and if you’d like a one, eight, or twelve ounce pour. Flow sensors automatically shut off when you have the desired quantity.

Seems like you get more foam than beer, but all in all it’s a cool bar top app.

Although beer is generally a good way to get people to come to your trade show booth, [Robofun.ru] decided to put a new spin on things. Instead of (or possibly in addition to) giving out beer, they decided to turn 40 Staropramen beer cans into a keyboard.

This was done using an Arduino hooked up to four Sparkfun MPR121 Capacitive Touch Sensor Breakout Boards, allowing them to act as keys. These inputs are translated via the Arduino into a standard output (we assume USB) that can be plugged into any computer.  Additionally, a Sparkfun MP3 trigger board was used to control the sound effects.  Rounding out the build, a Raspberry Pi computer was used to run the human machine interface, a large plasma display.
