Turning on PC speakers whenever there is music playing

Hack a Day Turning on PC speakers whenever there is music playing

If you’re like a lot of people, most of the time your computer speakers are on without actually playing any music. This wastes a bit of power, and [Bogdan] thought he could create a circuit to cut down on that wasted electricity. The result is a very tiny auto-on circuit able fit inside a pair of speakers.

The circuit is built around the ATtiny13, very nearly the smallest microcontroller available with an on-board ADC. When music is played on the computer, the ATtiny senses a bit of voltage in the audio line and switches a relay to power the speaker.

Of course, there is always the problem of music with a high dynamic range; if the sound played from the computer has too low of a volume, the ATtiny might turn the speakers off even if music is playing. [Bogdan] solved this problem by adding a timer to his code; if nothing is detected by the ADC for three minutes, the speakers turn off.



Assimilate UK! The British Music Industry Now Controls Your Internet


via TechCrunch Assimilate UK! The British Music Industry Now Controls Your Internet


One by one the UK’s ISPs are falling to a creeping censorship of the web led not by some secretive government organisation but by the UK’s music industry in the shape of the British Phonographic Industry, the British record industry’s trade association. There is no democratic check on what’s happening and little recourse left open to the average person.

In a nice piece of investigation, Zack Whittacker at ZDNet has unpacked what’s happening before our eyes.

Not unlike SOPA, the U.K.’s antipiracy legislation, the Digital Economy Act, has a “three-strikes” system leading to Internet disconnections, but it’s been put on hold for implementation until 2014. So to get around this delay, the music industry is going to the courts.

In April 2011, the High Court in London ruled BT must block access to file-sharing site Newzbin2. BT did not appeal the decision, creating a precedent which means any person or organisation can bring a further action along the same lines.

That test case has led to other ISPs being forced to block access to the Pirate Bay, using, handily, the “Cleanfeed” system built originally to block child abuse imagery.

That means that now six of the U.K.’s largest broadband providers have been ordered by the High Court to block customers from accessing The Pirate Bay.

Virgin Media, TalkTalk and O2 Broadband have acceded to the demand, but only TalkTalk has made it explicit that the BPI is to blame.

U.K. citizens have not been barred from circumventing the blocks, but the total ban could extend to 20 million users, about a third of the U.K. population, although the six ISPs forced to block access to The Pirate Bay serve more than 92 percent of the U.K.’s broadband customers.

So that’s that then. The ISPs have capitulated in the courts and there’s no democratic recourse over where this will lead.

The fact that the BPI’s actions have now created a precedent which could be used by anyone else means the UK Internet is now up for grabs by any wanna-be censor. Nice work BPI.

64 Billion Plays: What Online Music Looks Like Today (Infographic)

Published on ReadWriteWeb | shared via feedly mobile

In 2011, we collectively listened to 64,876,491,602 songs on the Internet. Whether it was on YouTube, SoundCloud, Rdio or MySpace, the citizens of the Web listened to quite a lot of music last year. Bands and musicians made over 3 billion new fans, who viewed artist profiles over 16 billion times. These are just a few data points recently released by Next Big Sound, a startup that tracks the popularity of music and individual artists across a range of digital music providers and social services.

Digital music only continues to grow and mature, as streaming services explode, Internet radio companies go public and developers begin using the power of open APIs to mash up sounds and services. SoundCloud alone saw 231% growth last year, while Twitter saw a 104% increase in music-related activity.


The top artists on the Web are mostly unsurprising. You knew that people can’t get enough Lady Gaga and Justin Bieber, for better or worse. Rihanna. Katy Perry. Adele. No shockers there.

What’s interesting, though, is how the Web is paving the way for unsigned, independent artists to reach levels of popularity that rival major label acts. This is especially true on SoundCloud, where unsigned artists flock to upload their recordings. But even across the larger Web, three unsigned artists broke into Next Big Sound’s “Social 50” list, which chronicles, the 50 biggest artists across all of the social and music sites that they track.

These numbers, while impressive, should be taken with a grain of salt. Next Big Sound has gone to great lengths to pull data from sources like YouTube, Rdio, Last.fm, Pandora, SoundCloud and several others. One service missing from their list is Spotify, which just launched in the U.S. this past summer and has seen enormous growth since then. Still, it looks like they’re using a pretty hefty sample of online music data to draw their conclusions. You can take a closer look at their methodology. if you’re curious.


Shooting a music video with iPhone 4s – National Geographic Adventure Blog

Recently, Camp 4 conducted another experiment: They shot a music video on a camera phone. While normally this would sound like a waste of time for filmmakers of their expertise, that was not the case. Shooting on the iPhone 4S, with its 8-megapixel camera and 1080p hi-def video, the team produced great results.

“The first digital video cameras we took with us into the mountains four years ago—to Pakistan—were shooting lower resolution and weighed significantly more,” says Tim Kemple, who directed the music video featuring singer Gillian Chase. “But even bigger than that to me is the idea that you can always have this camera with you—no set up, no setting down your backpack.” Pretty ideal for documenting your adventures.
