Kegerator tallies your pints on Untappd while you sit back with a cold one

untappd-auto-checkin

[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.

Cool Master advanced beer delivery system

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.

Brewing beer with LEGO

[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.

Automated Beer brewing

[Randyrob] is pretty serious about their beer. So serious, that he wanted to build a fully automated system for brewing. Dubbed the Halfluck Automated Brewing System, or HABS, it is actually his first micro controller project. You can follow along on the arduino forums to get a little more information, including the source code if you should want to build one of your own. There are a few videos on his youtube channel, but unfortunately, we didn’t notice any full tours of the entire thing.

Like some others we’ve seen, this one only handles the brewing aspect, not the fermenting stages. It would be interesting to see a system that handled it all. You could fairly easily get the machine to siphon it into a keg for final carbonation too.

Brewtarget: open source homebrewing

Several of us here at Hackaday Brew our own beer. Needless to say, we got a little excited when we saw members of the open source community building a brew tracking system. Brewtarget is an open source tracking system that you could download right now and begin tracking and building your recipes. It looks like there is a fairly active development group working on it and even a feature request form that seems to be filling up. Maybe we overlooked it, but there doesn’t seem to be an existing feature list. We look forward to seeing where this project goes.

Brewtarget implements BeerXML, which means it should also be compatible with Beershmith, a commercial application.

Doomsday Keg of Radness helps ring in the New Year

doomsday-keg

Lots of people buy noise makers for New Year’s eve, others opt to sing Auld Lang Syne – then there’s these guys.

The crew at Stone Brewing Company throw an annual bash at their brewery in celebration of New Years, and while [Dino’s] countdown timer is great for intimate settings, they needed something bigger to wow the crowd. A busted half barrel was all the inspiration they needed to build the “Doomsday Keg of Radness”.

[Mike Palmer], the Creative Director at Stone handed the keg off to the maintenance crew for some remodeling, and got ready to fit it with all sorts of lights and other goodies. Holes drilled in the keg were fitted with bright pulsing LEDs, while additional LED light strips were laid out around the perimeter. The bottom was cut out to accommodate a Moonflower LED module, and a 24” monitor was strapped to the side in order to display a countdown timer. An old Macbook jammed inside the keg runs the video display, while the rest of the lighting is remotely controlled with an RF transmitter.

Now mind you this all went down last year, but since the display was such a hit, they will be busting it out again for the 2011 celebration.

Check out the short demo video below to get a look at the Doomsday Keg in action.

Free-form Christmas ornament

Here’s [Rob]‘s free form circuit that’s a Christmas ornament for geeks. It looks great, but sadly isn’t powered through a Christmas light strand. It’s just as cool as the skeletal Arduino we saw.

Prototyping with flowers

Well this is interesting: protoboard that’s specifically made to make SMD soldering easier. The guys at elecfreaks went through a lot of design iterations to make sure it works.

We’ll call it Buzz Beer

The days are getting longer and cabin fever will soon set in. Why not brew beer in your coffee maker? It’s an oldie but a goodie.

Christmas oscilloscope

With just an ATtiny and a little bit of  futzing around changing the coefficients of a partial differential equation, you too can have your very own oscilloscope Christmas tree. Don’t worry though, there are instructions on how to implement it with an Arduino as well. HaD’s own [Kevin] might be the one to beat, though.

So what exactly does a grip do?

You know what your home movies need? A camera crane, of course. You’ll be able to get some neat panning action going on, and maybe some shots you couldn’t do otherwise. Want a demo? Ok, here’s a guy on a unicycle.
