Perfect Shots Every Time

December 28, 2010 by Caleb Kraft 23 Comments

A shot is a shot right? Well, not really. Usually we see a sloppy shot poured of a single type of alcohol and, depending on our current standing with the bartender, may or may not be full to the brim. The Pousse-Cafe makes an art out of your drinks by perfectly layering several liqueurs. Not only will it measure them out perfectly, but it is voice controlled as well. There are 3 liqueurs to choose from, as they were going for a specific, visually appealing drink (otherwise, why bother?). Judging from the pictures it looks like it’s using an arduino in conjunction with a laptop for control.

You can see a video of it in action after the break.

This Fire Extinguisher Serves Frothy Beverages

December 19, 2010 by Mike Szczys 16 Comments

[Ben Krasnow’s] friends always want him to bring a fire extinguisher to their parties, not for safety reasons, but to quench their thirst. You see, [Ben] uses old fire extinguishers as kegs for his home-brewed beer. They’re not all that different from the Cornelius kegs that most home brew setups use; they’re intended to dispense liquids under pressure, include a liquid exhaust valve, and a gas pressure valve. All he had to do was clean the stainless steel parts extremely well, replace the gaskets, and modify the input valve to use a quick connect for his CO2 system. For good measure he also added a low pressure meter to let you know the carbonation level.

Recently, he installed a home tap system that uses two of the extinguisher kegs. Our favorite part is the refrigerated hose loop that uses a fan to circulate cold air from the fridge all the way to taps.

Chest Freezer Temperature Controller

November 5, 2010 by Mike Szczys 11 Comments

[Mikey Sklar] finds himself in need of a temperature regulated refrigerator for fermenting foods like yogurt, kimchi, bread, and beer. After some testing he found that by building his own controller he can get a chest freezer to outperform an upright refrigerator at this task by 2-to-1.

The controller is based around an ATmega48. It includes a remote temperature sensors which you can see connected to the lower left header in the image above. On the back of the board there’s a relay used to switch the freezer’s power on and off. [Mikey] is selling a kit but the hardware and software for the project are both open source so build it yourself if you have the know-how.

A chest freezer is a great place to store Cornelius kegs… we’ll keep our eyes open for one.

NYC Resistor Takes On The Machine

October 7, 2010 by Jakob Griffith 3 Comments

Here we are with Episodes two and three (aka, NYC Resistor part one and two) completing the Take on the Machine Hackerspace challenge we mentioned a while back. For the challenge NYC Resistor took an old style slot machine and converted it into a drink mixing deviant; even making the device post a Tweet for every drink. However, it seems to be lacking refrigeration of some kind, could this be the downfall of a potential winner for the challenge? Up next is the Hackerspace Pumping Station: One: do you think they can compete? Is there a particular Hackerspace you can’t wait to see? Let us know!

Solid Ice Beer Caddy

September 5, 2010 by Caleb Kraft 31 Comments

brrrrr

[Rob] has made an astounding contribution in the effort to keep our libations chilled. Not content with merely refrigerating his cold ones, or even putting them in a cooler full of ice, he has built a beer caddy out of solid ice. Though it may look simple initially, you can see from his writeup that it actually took quite a few itterations to get it to freeze correctly, and then actually survive the process of removing the bottle placeholders. Ultimately, he found that glass bottles full of sand work best and you have to freeze the caddy in layers. Though he calls himself an impatient person, we’ve seen people who insisted on having their cold ones made frigid faster. You can see a video of the ice caddy after the break.

Beer Fridge Holds IPad Hostage

August 12, 2010 by Mike Szczys 15 Comments

A hackathon by the engineers over at Yelp produced this iPad-centric beer fridge. A thirsty dude bellies up to the contraption, swipes his or her RFID card, then dispenses a glass of frothy goodness. The iPad display shows information about what’s on tap, and allows you to give it a rating. This is based on kegbot but it has a few extra tricks. Instead of measuring how much beer is left via weight, this version uses a flow sensor on the beer lines. Temperature data is recorded from an analog sensor affixed to the keg itself, and the whole shebang is pulled together via an Arduino connected to the serial port of the iPad. You can even check on the keg over the Internet. See for yourself after the break.

RBD (robotic Beer Delivery)

July 13, 2010 by Mike Szczys 25 Comments

Those crazy programmers over at the Willow Garage are at it again. This time around they’ve created a robotic wench to deliver the beer. When thirst strikes you can fire up a web interface and drag a picture of your beer into a shopping basket. Once you submit your order the bot will raid the fridge and return with your frothy treat. It will even open the bottle for you but, as you can see after the break, this is where your beer becomes truly frothy.

So we’ve seen the PR2 playing pool, and now as a barmaid. Willow Garage just joined SparkFun on our list of places we wish we worked. Continue reading “RBD (robotic Beer Delivery)” →
