Having been faced with an empty beer fridge one too many times the team at Metalworks came up with an approval system for dispensing malted beverages. The trick was to remove the physical controls on a can dispenser. The only way you can get a cold one is to ask the machine via its twitter account. If there’s beer inside, it waits for one of your approved co-workers to give the go-ahead.
There are two versions of the machine. The first is a hacked refrigerator with a dispenser hole cut in the door. This resides in their Sydney office, apparently doesn’t work all that well, and is only shown in the video after the break.
The image above is version 2.0 which is located at their Singapore branch. It’s a much smaller device, but works very well since it started as a commercially available can dispenser. You can see the Arduino Leonardo and breadboard which make up the driver circuits.
There aren’t a ton of details on this, but it’s not hard to find about a million examples of an Arduino using Twitter. Here’s one that takes Morse code as an input and posts the message as a Tweet.

[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.
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.
Check out the video after the break.

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.
Be sure to check out this keyboard in action after the break. If this isn’t enough alternative input fun, why not check our post about how to make a banana piano and giant NES controller. Continue reading “Hacking Beer Cans for Fun and Publicity”
[Jeff] admits that he’s pretty well addicted to Untappd, a site he describes as a Foursquare for beer. Like his fellow beer nerds, he enjoys reporting the pints he’s had, even if they happen to be from his own stash of homebrew kegs. Untappd certainly supports this level of dedication, but it seemed silly to [Jeff] that he needed to grab his phone each time he poured himself a cold one in the comfort of his own home.
He took a look around the room and spied an Arduino doing a whole lot of nothing, so he set off to build a system that would allow him to automatically record his drinking habits without the use of his smartphone. The system is not overly complex, and measures pours using flow sensors, uploading the results to Untappd using their “check-in” API. [Jeff] was sure to include several other useful features into his build, including a lockout timer that prevents multiple check-ins when simply topping off a pint, as well as “neighbor mode” which lets you pour a round for friends without recording the pour.
Be sure to check out the build in its entirety on [Jeff’s] site, and let us know if you’re doing something equally cool with your keg setup at home.
The Cool Master is a beer delivery system which Innovation Thirst built as their qualifying entry for this year’s Red Bull Creation contest. It’s one of the best beer delivery concepts we’ve ever seen. Instead of tossing you a beer directly from the fridge, this offering brings the cold beverages directly to you. It even manages to de-cap the bottles before serving.
Mobility is provided by a six-wheeled base which allows for a zero-turn radius. The cooler acts as the body of the robot, and hides a hopper which carries a stock of bottles on their sides. When you want a beer, the bot approaches you, tilts the next bottle to the upright position, removes the cap, then raises the vessel on a beer elevator until it pushes its way through the rubber orifice in the cooler’s lid. Right now the device is operated using an RC controller, but there’s always room for adding autonomy and the ability to restock from a refrigerator. Don’t miss the demo video after the break.

[Matt] sent in a set of YouTube videos walking us through his LEGO Mindstorms controlled brewery.
[Matt] is using a RIMS brewing setup that recirculates and heats the mash to extract more starch from the grain. This results in a Maillard reaction in the mash and creates a richer, maltier flavor.
To control his RIMS setup, [Matt] is using a LEGO Mindstorms brick with a few LEGO temperature sensors attached to his plumbing. The LEGO provides all the temperature and pump control for a proper RIMS setup, perfect for the homebrewer who doesn’t want to bother with an Arduino or other microcontroller board.
As a small aside, the astute Hackaday reader will note our beer hacks category is woefully underpopulated. It’s nearly summer now and the perfect time to start brewing. If you’ve got a beer hack, be sure to send it in.
After the break you can see all of [Matt]’s RIMS/LEGO brewery videos, or you can check out his YouTube channel.
