Gertboard extender for Raspberry Pi ships to advanced tinkerers

If a seemingly infinitely programmable mini computer like the Raspberry Pi is just too... limiting, we've got good news: the Gertboard extender has started shipping. The $48 companion board reaching customers' doorsteps converts analog to digital and back for Raspberry Pi fans developing home automation, robotics and just about anything else that needs a translation between the computing world and less intelligent objects. The one catch, as you'd sometimes expect from a homebrew project, is the need for some assembly -- you'll have to solder together Gert van Loo's Arduino-controlled invention on your own. We imagine the DIY crowd won't mind, though, as long as they can find the fast-selling Gertboard in the first place.

Neil Young’s Pono music service wants to democratize high-quality audio (video)

Neil Young's Pono music service wants to democratize highquality audio video

Neil Young isn't shy when it comes to embracing new technology, something he put beyond question with his latest appearance on The Late show with David Letterman. The artist took the opportunity to reveal plans for his high-fidelity Pono music service. The aim is to tackle the poor quality in which he believes most people receive their music these days -- the humble MP3. Young's offering would comprise a three-pronged approach, including a music store with high-resolution recordings, a digital-to-analog style conversion technology, and portable hardware to listen to it all with. The simple intention is to offer music as it was originally intended to be heard, but at this time there's no detail as to what this actually entails (sorry specification fans).

According to Rolling Stone, the big three labels are interested, and the goal is to unify, rather than diversify, the quality of recorded content. The Pono players (that yellow wedge you see above) will serve up your existing catalog, but you'll likely need to re-buy some of your collection if you want the holistic experience. With no cards fully on the table, we're at the ransom of Young's celebrity endorsements, which all claim that the benefits are tangible. Young, of course, says "You can't get better than this, this is what they do in the studio," but until we get some details, or ears on, everybody knows this is nowhere.

Raspberry Pi teases finished Gertboard I/O extender, revs creative engines (Update: pre-orders open now, video)

Raspberry Pi teases finished Gertboard IO extender, revs creative engines

The Raspberry Pi faithful have been looking forward to the Gertboard almost as much as the main device itself: Gert van Loo's I/O extender promises to flash lights, spin motors and otherwise take on the tasks that the Raspberry Pi doesn't directly manage on its own. While we've seen work on the project since late 2011, the expansion now looks to be closer to reality following a fresh teaser. The refined design's biggest tweak is replacing its original PIC controller with an Arduino-powered chip -- an element no doubt familiar to the crowd that would already be looking at a very hackable, miniature Linux computer. Most everything else is a refinement, although Gert has brought in three physical buttons and two-channel analog-to-digital and digital-to-analog converters. We'll learn the full story later this week, and until then we'll be dreaming of all the off-kilter Arduino projects that might be made better with a little Raspberry Pi companionship.

Update: The wait turned out to be short, and interested parties ready to do some soldering of their own can pre-order the Gertboard for £30 at element14 now. Check the Raspberry Pi blog (2) for more info, or check out a video interview with Mr. van Loo himself embedded after the break.

Engadget Primed: digital audio basics

Posted on by

Primed goes in-depth on the technobabble you hear on Engadget every day -- we dig deep into each topic's history and how it benefits our lives. You can follow the series here. Looking to suggest a piece of technology for us to break down? Drop us a line at primed *at* engadget *dawt* com.

Primed

Digital audio. There's a very good chance that you've enjoyed some today. It's one of the more universal aspects of technology. In fact, perhaps the more relevant question would be, when was the last time you listened to an analog format? The truth, for many, will be quite some time ago -- vinyl purists and the odd cassette fanatic aside. Yet, despite its ubiquity, there's a lot of misunderstanding and confusion about digital audio. Some believe it'll never match analog for true fidelity, some assert quite the opposite. Many lament the lack of a tactile format, while others love the portability that comes with zeros and ones.

In this installment of Primed, we take a look at the history of digital sound, as well as provide an introduction to some of its key components, with the view to helping us understand it better. Wondering what bitrate to encode your MP3s at? Or whether you should choose a 96 or 44.1KHz sample rate? We thought as much. By the time we're through, these questions should no longer lay heavy on your mind, and you can enjoy that latest Knife Party, or Britney track as much as its bit depth allows. What's bit depth you say? Well, read on to find out...
