Last night, PC Magazine's PJ Jacobowitz and I walked into the Park Ave Country Club in Manhattan in the pouring rain to test all 7 of the digital breathalyzers we've reviewed over the past couple of weeks against the big Kahuna: the Lifeloc FC10 digital breathalyzer ($480), which is used by law enforcement.

If you've ever been pulled over for drunk driving, you're probably familiar with the FC10. It's very easy to use: you just turn it on, look for the "wait" to disappear from the LCD screen (which is only about 10 secs), and blow. It gives you a response in under 10 seconds, and in about 20 seconds, it's ready for use again. It can detect blood alcohol levels between 0.000 to 0.600 (which we hope no one ever has to see the latter number, because that's like death). It uses 4-AA batteries.

We used the FC10 as the standard to go by.

At 6:14pm, we took 1 vodka shot. Then 2 minutes later, had another. After 20 minutes (6:36pm), we tested our BAC levels with the FC10, and then with the remaining breathalyzers. We kept going back to the FC10 to make sure we were at the same BAC levels.

We weren't alone at the bar, either. We met two really friendly older men who were amazed that we were sitting there with all of these breathalyzers. Of course they wanted to try them, and being the nice geeks that we are, we let them. Actually, PJ's exact words were, "Sure, we'll blow you." (I looked at him and he realized what he just said.)

All of the breathalyzers were good to go, except for the Brookstone model. We had to get the bartender to blow into it since he wasn't drinking in order to recalibrate it.

CONCLUSIONS: The digital breathalyzers closest to the FC10's results were the AlcoScan AL6000 ($149.95) and the AlcoHAWK ABI ($99.00). So, we recommend buying either of those two. Parents who just want to know if their teenage kids were drinking as they're stumbling through the doorway, can go with any of these breathalyzers.

So now that we've tested all of these breathalyzers and have come up with our favorites, what do all these BAC numbers mean? Just for you, we've listed a chart that we found in the AlcoHAWK Elite's manual on BAC levels and the specific effects you should be experiencing while at those levels. Check out the chart here.

That's all! We hope you've enjoyed reading about our breathalyzer tests. Now turn your computer off, walk out the door, and go get drunk! But don't say we didn't warn you about the effects!

A new research project at MIT's Media Lab aims to turn every cell phone or PDA carrying member of the public into a podcaster, and every mobile device into a virtual podcasting studio.

The first reportedly working prototype was built on a Motorola A1000 cell phone, and is currently being tested in Spain as part of the Electronic Lens project. A live demo of the new project, which has been dubbed "RadioActive," should be available soon.

The RadioActive project, which Donath created with student Aaron Zinman, defines a large-scale asynchronous audio messaging system, or mobile audio forum. In this system, voice messages, which are short audio sound bytes, are exchanged between groups of users via mobile devices, like cell phones or PDAs, as a method of "discussion-on-demand."

Just like an email application or an RSS reader, RadioActive supplies its users with an inbox, which displays the first message of discussion threads that have been subscribed to or are contextually relevant. For instance, location may be one factor the system takes into account when determining contextual relevance. In this scenario, threads relating to New York City restaurants may appear in the inbox as the user walks around Manhattan.

Blogging Molly loves her girly bags, and this Targus Radiance Tote is no exception. It comes in my new favorite color this season is what Targus calls Sage, a lovely bronze hue. The Radiance is a great bag in that it totally doesn't look like a laptop bag at all, and I can fit all my other junk in there. Since I don't have a car, I consider my handbag almost like a car trunk, and this definitely fits.

The straps and bottom are made of a cool faux crocodile fabric and the inside is well-padded with lots of pockets and compartments for your cell phone, camera, MP3 player and your myriad gadgets.

I used it over the course of a few days, sometimes toting my laptop around, sometimes, not--I can definitely see using this as a "regular" bag. I love versatility! This would make a good companion to the Brenthaven Edge bag I tried out a few weeks ago. While that one was more practical, this one has style.

My one complaint is that the shoulder strap dug in after awhile, but this should only be a problem if you do a ton of walking.

You can fit 15" laptops in the Radiance Tote, it weighs about 2 pounds and also comes in Petal Pink. (My other favorite color.)

The best part: this bag costs an amazingly low $39.99! Blogging Molly loves a good deal most of all.
