Fresh hacks every day
We're not sure if there's enough time to get a parts order delivered, but no geeky New Year's party will be complete without a party buzzer that doubles as a Breathalyzer. The Buzzed Buzzer hides all of the necessary bits inside of a paper and plastic party favor. We guess it only buzzes if you're over the limit? Actually that's not the case at all. The accuracy of the sensor used in the project … [Read more...]
[Al] at Open Gadgets just put the finishing touches on his Android breathalyzer. It's the perfect thing to install on ex-girlfriends' phones to prevent 2 a.m. drunk dialing. 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 … [Read more...]
[Phil] had a bunch of Shiftbrite modules set aside for an LED table project, but before he could get around to it, he decided to use them to build a prop for his friend’s bachelor party. Expecting plenty of drunken revelry, he constructed the Arduino Wine-o-Meter - a carnival “Test your strength” style breathalyzer. The 25 Shiftbrite modules are lined up in a column, which is connected to … [Read more...]
While handheld breathalyzers are pretty novel to have around while drinking with friends, there's nothing exciting about a $50 off the shelf unit. If you really want to grab people's attention, you have to get creative and built something like [Batsly Adams] and his friends did. One evening, he was casually drinking with some friends and playing around with an electronic alcohol sensor. They … [Read more...]
Sure, [Hunter Scott's] Breathalyzer can only differentiate between hammer and sober, but look how nice it came out. He's using an MQ-3 alcohol sensor which, from previous projects, we know is very difficult to accurately calibrate. But if you want to monkey around with embedded systems you've got to have a goal. [Hunter] chose a gorgeous aluminum project enclosure, adding a big LCD display to … [Read more...]
Okay, this may not be saving any lives, but it makes for a fun novelty at your next rager. Most Breathalyzers aim to keep you from driving when you've had too many. 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 … [Read more...]
[Daniel] wrote up a quick tutorial on interfacing with the MQ-3, or better known Breathalyzer from SparkFun with Arduino. While we would have used perhaps an op-amp/comparator based system and kept it in a much smaller package, the idea was so quick and simple and enjoyable we hoped an article might keep some hackers from drinking and driving. [Thanks CletustheYokel for pointing out our silly … [Read more...]
