LED lab coat makes you the nerdiest scientist in the lab (and other stuff you missed)

ProtoTank (Instructables)

Number nerds, take note: Today (12/12/12) marks the last repeating date of this century, which some have dubbed "soundcheck day" (one two, one two...). Now that we got that little fact is out of the way, here's a look at what you might have missed while staring at your calendar.

Custom lab coat makes you shine [Instructables]

The standard-issue lab coat doesn't exactly put you at the height of fashion, but a smart little mod posted over at Instructables will guarantee to make you stand out.

Fitted with LEDs, this custom coat can change colors and sense when your lab friends have been hitting the liquor thanks to its built-in breathalyzer. If a boozy friend gets a little to close the coat will turn from glowing a positive green to a red. The magic behind this coat is an Arduino board hooked up to LED spools, a sensor (for the breathalyzer), trusty old velcro, and some portable batteries.

You can find a full 11-step rundown on how it was made over on Instructables.

Update your Facebook from beyond the grave—whether you like it or not... [ReadWrite]

A recent ReadWrite report details how users are seeing “likes” that either they or their friends never made. These out-of-character “likes” are also seemingly being made by people who have passed away.

Facebook explained that they will often show page “likes” people have made more than once, which means that a page you liked in March of 2010 could appear in your friends' newsfeeds again in December of 2012—regardles of whether the user in question happened to have died in the meantime. However, user reports go against the explanation, stating that certain “likes” were never made—such as a vegetarian liking McDonalds.

The mystery behind these supposed “fake likes” isn’t wholly clear, but as ReadWrite points out, it’s not good practice and it devalues Facebook’s ever growing data set.

DIY Arduino radio reads out your Tweets [Hack A Day]

Keeping up with your Twitter feed can be a task, and that’s why a New York University student designed a unique way of dealing with a busy feed—a radio that can read out your tweets.

The DIY radio, constructed by William Lindmeier and dubbed the Magpi Radio, consists of an Arduino board and Raspberry Pi machine. These connected devices communicate with a nearby remote computer which provides the required text-to-speech service.

What’s neat about this project is that you can use the radio's knobs to change “channels." These channels are made up of your Twitter lists, so you can easily switch between who you hear Tweets from.
