Commercial Breathalyzers Help You Know Your Limit

Commercial Breathalyzers

Drinking and driving is always a bad combination. But it can be hard to tell, once you’ve started, when it is time to call a cab. Fortunately, commercially available breathalyzers are helping people to know when that limit has been reached. This is becoming more important as new ‘buzzed driving’ laws are being put forth in many states. Even one beer can land you a ticket now in some areas – all the more reason to drink at home with your kegerator home draft system!

We’ve come a long way in breathalyzer technology – according to wikipedia, the original roadside breath device used for alcohol testing used by the police was born in 1938, and was called the drunk-o-meter. Developed by Professor Harger, the drunk-o-meter took the suspected drunk’s breath into a balloon and pumped the breath through a chemical solution that changed color if there was alcohol in the breath, and a greater alcohol level was reflected by a more extreme color change.

Now, infrared, fuel cell, and semiconductor technologies are all different ways in which different breathalyzers operate. Of these, the semiconductor, also known as a silicon oxide sensor, is the least expensive and also the least accurate of the technologies. Semiconductor breathalyzers are prone to contamination and cross readings from chemicals other than alcohol that may be present in breath, and should be checked every six months to see if they are working properly. The 2010 BACtrack S75 Pro is one of the most accurate commercially available semiconductor breathalyzers. It can measure 0.000 percent to 0.400 percent BAC (Blood Alcohol Content), takes an air sample from over five seconds, and has a sensor accuracy of +/- 0.005 percent at 0.100 percent B.A.C. This unit costs $150 or less.

A more inexpensive version of semiconductor breathalyzer is BreathScan. This unit acts like disposable pocket version of the original Drunk-o-meter, using a colorimetric change. These units only cost a few dollars each, so they are a good choice for an inexpensive glove box item, for those rare situations where one is not sure about one’s B.A.C. Keep in mind that the criminal statutes concerning DUI or the new buzzed driving laws can vary between states and countries. BreathScan offers .04%, .05%, and .08% testers to compensate for these differences.

Platinum fuel cell breathalyzers work a bit better, usually requiring only yearly maintenance. One such breathalyzer is the BACtrack S80 Professional Fuel Cell Technology Breathalyzer. This unit has a test range of 0.00 percent to 0.50 percent BAC. It features a replaceable mouthpiece, so you can test your friends breath in a sanitary fashion, Xtend Fuel Cell Sensor technology for low power consumption, and a proprietary flow check that ensures a deep-lung air sample. Comes with six mouthpieces, 2 AA batteries and hard carrying case for around $150 to $200.

Another fuel cell unit is the BreathKey Breathalyzer, a digital key chain breath alcohol tester. This unit is lightweight – weighs less than an ounce, and is certified by the FDA to be +/- 0.010 percent at 0.080 percent BAC (blood alcohol content). This breathalyzer is not as accurate as the BACtrack Pro breathalyzer, but comes considerably cheaper, right around $$50 to $70, and is made in the USA!

Apart from BreathScan, you can see how your money is probably better spent on beer for your kegerator than a breathalyzer. Drink, don’t drive.

Kegerator Robots

Beer and robots are a great combination. As industrial America has disappeared, industrial art and hobbies have sprung up, utilizing the tools of the bygone industrial age. Now, we can count along with the many technological wonders of the modern age, beer launching robots, beer serving robots, automated home breweries, and even robot kegerators. A beer-launching robot has even been seen on the Late Show with David Letterman.

Robot building just goes better with beer. There are few hobbies that don’t go better with beer – granted, it may make hobby more dangerous, but with danger comes excitement. With excitement, danger, and beer, usually there is blood as well. It follows naturally that roboticists making robots in there spare time, drinking beer, would make such robots as the ‘killer’ robots pictured here. These robots, the Subjugator, Drunken Master, and Spiderbot, were made by Christian Ristow in association with RoboChrist Industries.

A decline in industrial manufacturing and industry in the United States has not meant a decline in inventiveness in the United States. This is especially true when it comes to beer and robots. Coming out of the home brewing revival in the 1970s was also a revival of the D.I.Y.(Do It Yourself) mindset. It took a while for D.I.Y. beer and D.I.Y. robots to meet up, but finally, we are there. Sadly, most beer LAUNCHING robots can still only fire commercially produced canned beer, and not home brew. However, these two hobbies come very close with robots such as Wired’s Beer Robot – a robot kegerator.

The engineers over @ Yelp.com took a keg and tap, an Arduino, an RFID reader, and an iPad and turned them into an amazing kegerator robot. The device not only tracks who’s been drinking but also tracks information about the beer as it’s poured, including the temperature and ratings of recently poured drinks (so you’ll know when the keg is on a roll). They even put together a bookmarklet to monitor and track the keg remotely.

 

 

It should be noted that the recent wave of D.I.Y. robot building has even taken the term “home brew” to describe many garage style hobbies. This term is often used to describe a hobby interest that comes from a technical or industrial field, but is made at home, such as home brew computers, home brew robots, and even engines. This is further proof of the connection between beer and robots.

One great moment of inspiration and promotion of home brew robotics was when the Late Show with David Letterman had a special guest: the Beer Launching Fridge. Also, the beer launching robot’s maker, John W. Cornwell, Duke University graduate. The Beer Launching Fridge that Mr. Cornwell invented launches beer up to 20 feet, and is remote controlled. In a blog post, Mr. Cornwall expressed the possibility that he may make his Beer Launching Fridge commercially available, and with improvements: the new design would allow a user to swivel the robotic armature with the remote, effectively aiming the launcher.

The phenomenon of beer and robots is not only confined to the garage and DIY inventors. Asahi has built a little robotic bartender that stores and pours beer. This invention can be seen at the following link: http://www.youtube.com/watch?v=2tXmGYk_A_c This robot seems to be built more for cuteness than efficiency, though. It takes about three and a half minutes for it to pour a beer, and it spills some, too.

One great take on the beer launcher is a mechanical unit which is foot pump operated. The ‘Ultimate Tailgating Machine’ holds 12 cans of beer and was the final group project for three student of a Design Class at U of I. See it in action at the following link: http://www.youtube.com/watch?v=LCIGIe2T4j0 Brought to the world by Dan Larson, Justin Tobin, and Steve Walker.

As we can see, beer, kegerators and robotics are a great combination, with potential for great fun.

Decorate Your Kegerator For Independence Day

Decorate Your Kegerator For Independence Day

Independence Day, which is celebrated on the 4th of July each and every year, is a day to celebrate America’s independence, as well as all things that makes this country great. The holiday is observed by most businesses and is a federal holiday, which means that not only can you celebrate the freedom of our country, but you can celebrate your freedom from the workplace, at least for one day. Independence Day is a big day for parties, parades, BBQs and celebrations.

And, where there are celebrations, there is a place for kegerators. If you own a kegerator and are hosting this year’s 4th of July festivities at your house, you can supply cold, fresh tasting beer to your guests right from the tap. This is usually a big hit, since an icy cold beer on a hot summer’s day is not only festive, but refreshing. Even if you are not hosting this year’s Independence Day celebration, you can still bring the cold draft beer (make sure it’s a domestic brand!) to the party if you have a portable mini kegerator. Your host is sure to appreciate that!

When July 4th rolls around, no matter where the social gatherings take place, there is almost always plenty of red, white and blue to go around. You’ll find flags flying, red, white and blue balloons blowing in the wind, red, white and blue paper goods and decorations, and even some red, white and blue food. So, why not join in the patriotic spirit by not only filling your kegerator with great tasting, American beer, but also decorating the appliance in red, white and blue so it can become a centerpiece of the celebration?

Decorating your kegerator in patriotic colors is fairly easy to do. Depending on the size of your kegerator, as well as the exterior surface material, you have a few different options. For example, if the exterior surface of your kegerator is metal, you can attach magnets in the form of American flags on it. You can wrap your kegerator in red, white and blue boas, leis, or even crepe paper. You can even use patriotic looking tablecloths to cover your kegerator – all you need to do is to cut them down to size. Using vinyl tablecloths is best so any drips from the kegerator do not ruin the decorations.

If you really want to get into the holiday spirit and decorate your kegerator in a patriotic motif, whether just for the 4th of July holiday or all year long, you can buy a kegerator wrap that is custom made specifically to fit the exact specifications of your kegerator. Kegerator wraps are made from vinyl wrap, the same type that is used to wrap cars and trucks with advertising graphics, and can be the perfect way to customize your kegerator and proclaim how proud you are to be an American. See our post on Halloween Kegerators.

There are many ways that you can decorate your kegerator for Independence Day. And while it is not necessary to do so, a few red, white and blue inspired decorations on the exterior of your kegerator can subtly enhance the appreciation of the great tasting, refreshing American beer that’s on the inside.
