His company, WifiThingis bundling the Texas Instruments toolchain and mesh networking with a sort of plug-and-play web interface. The board uses a MSP and two other TI Networking chips to make setting up, logging data, and controlling outputs simpler. The web interface looks interesting, but in our experience this sort of approach only saves time up to a point.
Though, there are some projects where you would like a simple way to log data from multiple sensorsif this can do that easily and more importantly, cheaply it might be very cool.
We are interested to see if the open source software is easy to integrate without buying their hardware. Either way, after setting up a simple circuit to heat the coil in the breathalyzer, and translate the data into a signal usable for the chip, [spillsman] was able to record alcohol levels and even keep a, perhaps unwise to record, high-score from his phone.
The Buzzed Buzzer hides all of the necessary bits inside of a paper and plastic party favor. A Teensy 2. Powered by a Lithium cell, it monitors an MQ-3 Alcohol gas sensor and drives a buzzer.
The components are just small enough to be hidden by the cone of the party buzzer. You can see a demonstration of this in the short clip after the jump. The project started off as a talking breathalyzer connected to a computer that tweeted your BAC, gave weather and stock readouts, and functioned as a photo booth. Since the first reveal of his project, [Al] moved from the desktop world to the mobile domain. The breathalyzer itself is contained entirely in an Altoids tin. An alcohol sensor in the project measures the alcohol content of the surrounding atmosphere and reports this back to a phone over Bluetooth.
The 25 Shiftbrite modules are lined up in a column, which is connected to an Arduino tucked away in a cardboard box. While it has been noted in the past that this sensor is pretty inaccurate, it seems to serve his purposes quite well. It looks pretty cool, and we imagine that it will ensure that the party stays lively throughout the wee hours of the night. Check out the video below to see [Phil] walk you through a demo of his Wine-o-Meter.
One evening, he was casually drinking with some friends and playing around with an electronic alcohol sensor. They quickly put together a NES ROM that would play sounds, changing the pitch depending on how much alcohol the sensor detected.
In no time, he and his friends had compiled graphics, a soundtrack, and the code to drive their game, DrunkenNES. To play the game, each player must blow into a gutted NES cartridge that has been fitted with the alcohol sensor. The switch on the bottom selects between on, off, and charging modes. Everything runs on 3. An Arduino is the brains that pulls everything together. Okay, this may not be saving any lives, but it makes for a fun novelty at your next rager.
The Squidalyzer encourages party-goers to drink more and more by treating a high blood-alcohol-content with great fanfare. An Arduino, a gas sensor, and Processing all come together for this hack. A television interface tells you when to blow into a cup which houses the sensor, and gives a reading of what it measures. Watch the demo after the break to see the fun [Geoff] had with it.

This is probably because alcohol is acidic and the antacid tablets used in excess will nullify the acid in the alcohol. The only problem is that you'll be constipated the next day or two but beats paying off a lawyer or doing community service.
Strange enough I did that in Germany and thought I had passed. Whether I passed their legal limit of not they let me go only to find me later at my campground and arrest me.
I think it may have had to with a shakedown than a legal issue. It might beat hiring a lawyer or community service, but what if you kill someone? Paralyze them? Is that worth beating a test for? Driving drunk is stupid, plain and simple. And if you honestly want to find a way to beat the breathalyzer, so are you. What if someone drove drunk and killed a family member of yours, would you still be coming to Answers and finding out how you could do it and not get caught?
The test measures the alcohol content found in the bottom of your lungs which is why you need to breathe so much into it which translates into what your BAC is. So no, nothing to do with your stomach is going to help you. I would wonder where the chem teach got his degree from because that is not true.
By the way-alcohol-the drinking kind-is not acidic-c2h5oh doesnt become acidic until it turns to vinegar-c2h5cooh-dont take that teacher in any chem courses!!!
First of all, the question itself is absurb. Drinking and driving is a terrible idea. My youngest niece 2 yrs old and my Cousin 27 were both killed because someone decided to climb behind the wheel after drinking far too much. Would you like to tell them how if the guy who killed them had just used antacids then he might've passed the test? Nevermind the fact they were killed. Secondly, alcohol is so toxic that it is literally excreted through the lungs.
How the test measures alcohol content.We hear and read about drivers involved in an accident who are later charged with drunken driving, and usually a news report on the accident will say what the driver's blood alcohol level was and what the legal limit for blood alcohol is. A driver might be found to have a level of 0.
But what do those figures mean? And how do police officers find out if a driver they suspect has been drinking is actually legally drunk? You have probably heard about the Breathalyzerbut may wonder exactly how a person's breath can show how much that person has had to drink.
Of the 42, traffic deaths in the United States inabout 38 percent were related to alcohol. Drivers who can pass roadside sobriety tests -- they can touch their noses or walk a straight line -- still might be breaking the legal limit for blood alcohol and be a hazard on the road.
So police officers use some of the latest technology to detect alcohol levels in suspected drunken drivers and remove them from the streets. In this article, we will examine the scientific principles and technology behind these breath alcohol testing devices. How Alcohol Works. How Beer Works. How Blood Works. Did you really pay attention to how much you drank before you got on the road, or are you just guessing? Don't worry, the police can help you out with that. Up Next How Alcohol Works.I was just wondering if there were any ways.
I administer a dozen or so breath tests per month in my employment as a probation officer. People try to spoof the test ALL the time. The phony exhaling doesn't fool anyone and just irritates me. Stating that you just took Nyquil doesn't work. The Public Defender and I split a bottle of of Robitussin to see if a Defendant was lying in court she was.
If you have a buzz and hyperventilate, you can blow a falsely low reading - possibly enough to elude a roadside sobriety test, but if you're taken to the pokey, you'll be given a test on a more sophisticated Intoxilyzer rather than the hand-held Alcosensor. The judges took a couple Alcosensors to the annual Judge's Retreat to play with them and try to figure them out. No, breathalyzers work by what's in your lungs, not what's in your mouth.
You cannot cheat a breathalyzer! There aint no way to beat it. But you have the right not to take it. If you do not take it,your lawyer will have a much better chance of getting you off. Don't blow hard, and slightly cover the tube with your tongue. The whole penny in the mouth might work, but I haven't tried it. Answer Save. Well, almost nothing Hyperventilating to temporarily reduce the gas level of alcohol CAN knock you down about.
The Alcosensor retains the last ten readings. Some of those old boys caught a Buzz! Call a cab or use a DD. Eventually, you'll be caught or wreck. Ways To Beat A Breathalyzer.

Had you considered that drinking under the influence is a morally reprehensible thing to do and that you deserve to be incarcerated, have your license taken away and be socially stimatized? Show more answers 3.Testing your breath can do more than reveal whether you need to brush your teeth — it can now yield clues about how much fat your body is using for fuel.
The pungent smell of acetone permeating from a keto dieter's gullet can be a fairly decent indicator of whether that person's low-carb eating strategy is on track. A new breathalyzer tool released yesterday aims to help people measure just that. The goal of the popular keto diet is to move the body into a state of ketosis, in which the body burns fat for fuel instead of relying on carbs. Our systems naturally enter this mode when starving, but the keto diet hacks our systems to force ketosis by zeroing out the intake of sugar and carbohydrates and upping fat consumption.
But it can be difficult for keto dieters to determine how well their bodies are staying in ketosis without help from a urine test or finger prick for blood. Now a startup called Keytofounded by two Silicon Valley doctors, is offering a simple breathe-in-breathe-out test that can give people a sense of their metabolic state.
It can take several weeks to get into this mode, but once a person does, they may develop what some call "keto breath" which might smell pleasantly like a baby's breath or may be mildly off-putting, depending on who you ask. But there are people out there who have really, really sensitive noses. The scent is a byproduct of the body's work converting fat into fuel, since the process excretes three ketones, one of which is acetone.
Ketones are the acids that are produced naturally by bodies as they break down fat for energy, which is a big shift from our metabolic default: fueling up on glucose from carbs.
The founders of Keyto — Weiss, a cardiologist at UCSF in San Franciscoand Ray Wua doctor who has developed other diet apps — re-jiggered an alcohol breathalyzer testwhich traditionally measures ethanol, to monitor acetone levels instead. That makes it a fairly reliable ketosis meter. Weiss originally started developing the device to help more of his patients manage diabetes, obesity, and other metabolic issues without drugs.
But because the tool can give keto dieters instant feedback, it has garnered broad interest: More than 9, people backed Keyto's Indiegogo campaignand the company says it has shipped 14, breathalyzers in its pre-launch phase.
The device is a battery-powered, handheld breath-measuring stick that pairs with a smartphone app. To perform a keto breath test, Keyto users open the app, then take a long, slow breath in and exhale into the tube for about 10 seconds.
After that, the app reveals a "Keyto Level" ranging from 1 not in ketosis to 8 deep ketosisbased on how much acetone vapor is detected on the breath. The app also tracks a dieter's progress over time, linking their ketone level numbers to their weight. He said the tool didn't always pick up a carb-heavy food like a donut if he tried to get a reading right after eating it. But for the most part, Keyto seemed to register how well he stuck to his low-carb plan: Hickey's readings plummeted when he indulged in some cake at a friend's wedding, yet remained relatively stable when he cooked for himself at home.
The device has to be connected to the internet to work, so Hickey said he couldn't get instant breathalyzer measurements on the subway during his morning commute. But he liked getting quick-fire feedback about how he was doing every day.
In that regard the Keyto was great, even if it by definition only approximated ketosis. Plus, he added, Keyto looks close enough to a vape pen that he didn't stand out too much when using it.
Which isn't the best look, but is decidedly not the worst," he said. Keyto is not the only keto breathalyzer on the market. Keto diets are soaring in popularity, and mounting evidence suggests the eating plan can be a health boon for some people.
Going keto may help reduce Type-2 diabetes riskand the diet is well known as an effective approach to dealing with tough-to-treat epileptic seizures in children. Many keto-lovers say that the high-fat plan both helps them lose weight and also lifts some mental haze. Wu and Weiss said — much to their own surprise — they have also both become keto adherents. They have taken to using the breathalyzer daily on themselves, while sometimes stoking "friendly competitions" among Keyto users to see who can get the best ketone score.
But they both caution that any single reading should not be taken as an absolute indication of success or failure in low-carb eating. Plus, the keto diet is not for everyone. Some initial evidence from small-scale studies in athletes and others suggests that going keto can significantly change cholesterol levels in the body, and it's not clear yet whether this effect is good or bad.New generations of ignition interlock device have to ability to randomly ask for your breath sample when you are driving to make sure that you are not drinking while driving.
If you failed the test while driving, your car horn will went off like crazy and you car engine will slowly shut down. Since ignition interlock has become popular in most developed countries, people have been wondering if the ignition interlock device can be tricked.
Most people see the ignition interlock device as the chain that will not allow them to party with their friends. Some other sees the ignition interlock device as a safety device to keep their whole family safe when driving. Here is our top list that people have tried in order to trick the ignition interlock device:. Many people are trying to trick the ignition interlock devices by eating a hefty amount of strong flavored food such as onion, coffee, breath mints or some others.
Consuming coffee or sugar will definitely help you in gaining more consciousness and may really help you in driving home after some heavy drinking. But caffeine or sugar will not be able to change your alcohol content in your blood and the ignition interlock device will still give you a positive reading.
This is a ridiculous method. Perhaps the one who said that is not smart enough to even read the composition in the mouthwash they are using. Zima usually smell weaker than most liquor and beer. But still, contain alcohol and will increase the alcohol level on your blood. One young man from Canada, tried to use his underwear as a filter. Silly him. However this is not the end, as another 59 year old man tried to fool breathalyzer with full mouth of feces.How a breathalyzer works (alcohol sensor)
In both cases, these two were not able to start their cars. There are also some genius that said by putting a penny under your tongue will help you to trick the ignition interlock device. They said it is due the copper concentration on the penny will help you change your alcohol level in your blood.
Well, since s, pennies have been made of However — you can be arrested even with lower levels. There are few other intersting methods that will be described in the following articles. I am curious because of a family member who has the interlock system in their truck, and have been told by his friends, that he is rigging the interlock with a soapy concoction he uses I guess to breathe into the breathalyzer.
I think his friends are blowing in the breathalyzer for him. But they are saying he has rigged the interlock. I have contacted his interlock company and looked at data of his breathing times. What is the truth?Surprisingly even to us is that we managed to confirm a way to beat the breathalyzer.
In a blog post from last week, we ask for input concerning theories to beat the breathalyzer. We put this out there because last Thursday we had a testing session drinking event in our office to refresh ourselves on issues with breath-testing equipment, and to try some of the theories we have heard of to beat the breathalyzer. First, we tested the devices to ensure they were calibrated using both wet-bath and dry-gas standards as appropriate.
All of the equipment appeared to be functioning. Then we tested ourselves on a couple of devices to ensure we had no alcohol in our systems. Then we started to drink. Assuming the breathalyzers were correct, and we base that assumption on having conducted multiple tests on a number of different breathalyzers, we concluded a few things about ourselves. For example, Paul eliminates alcohol from his body very quickly.
Kyla shows almost no symptoms of having consumed alcohol, i. Perhaps the most interesting thing is that partway through the evening one of our Alco-Sensor IVs completely lost its calibration.
Only 90 minutes from the time it had last been checked and found to be properly calibrated, it suddenly began to report readings that were.
When we tested the ASD, we found it was then giving the wrong readings each time. How do you feel about this type of device being used to justify IRP punishment? As far as the myths are concerned, first, we tried a penny in the mouth. The sound of a person speaking with a penny in their mouth is similar to the slurred speech of a person who is really drunk. So it increases the likelihood that you will be suspected as impaired by alcohol.
The penny myth is a myth. We used old copper pennies and newer ones. It had no effect whatsoever on the breath testing results. If you put a penny in your mouth to try and beat the breathalyzer, i.
