Raspberry Pi GPIO Joystick | Chris Swan's Weblog After getting MAME going on my Raspberry Pi so that I could play old arcade games. I wanted to hook up a proper joystick. Back in the 80′s I had the excellent and ubiquitous Competition Pro 5000. As mine (foolishly) got sold with my Amiga stuff I got one on eBay, and it came in the original box: The first step was to get it hooked up to the RPi general purpose input output (GPIO). I used a breadboard with my homebrew Pi Cobbler at one end and a similar connector at the other hooked up to an old PC serial card cable that has the right (male) DB9 connector for the joystick plug (female). Since I was originally planning to use gpio-keys I used the joystick pinout to hook up to the RPi thus: Up -> 11 (GPIO 17)Down -> 13 (GPIO 22)Left -> 15 (GPIO 23)Right -> 16 (GPIO 24)n/cFire -> 7 (GPIO 4)n/cGNDn/c Blind alley Having already seen gpio-keys I thought I’d be using that, but when it came to the crunch I didn’t know where to start – I probably need a package of RPi kernel source.

How To Extract Sheet Music From YouTube Videos ⚙ Co.Labs ⚙ Code + Community Picking out the different parts of a song after it’s been recorded is like naming every ingredient of a cooked dessert: It's difficult. With its new algorithmic approach, Chordify is the latest to attempt the dissection. The service not only displays sheet music for locally uploaded songs, but for a wide selection of streaming music found online. Unlike other reverse engineering solutions, Chordify makes it as simple as pasting in a link from Deezer, SoundCloud, or YouTube, turning them into sheet music you can play along with. The web service also uses the algorithmic approach based on cofounder and computer music researcher Bas De Haas’s PhD dissertation from Utrecht University. Instead of picking out every note in a piece of music, which is very difficult, Chordify looks at the big picture of songs. It’s obviously pretty complex under the hood, but boiled down, the service uses the VAMP plug-in to filter the audio and separate it into different parts. [Image: Flickr user Dana]
How to Turn a Raspberry Pi into a Low-Power Network Storage Device Mix together one Raspberry Pi and a sprinkle of cheap external hard drives and you have the recipe for an ultra-low-power and always-on network storage device. Read on as we show you how to set up your own Pi-based NAS. Why Do I Want to Do This? The benefit of having an always-on network storage device is that it’s extremely convenient to have your data (or backup destination) always accessible to the computers both inside and outside your network. Our office server, for example, runs 24/7 and consumes almost $200 worth of power a year. We’ll be the first to grant you that a full fledged server is going to have more storage space and the capability to do more work (such as transcoding a multi-terabyte video collection in a reasonable span of time). What Do I Need? In addition to the gear you’ll need from the Getting Started with Raspberry Pi tutorial, you’ll only the following hardware: One (at minimum) USB external hard drive for simple network backups and file serving or That’s it!
The 10 Smartest Cities In Europe | Co.Exist | World changing ideas and innovation When it comes to smart cities, Europe is the model for the rest of the world to learn from. European cities tend to be denser, have better public transit, larger commitment to cycling and walking, a stronger focus on sustainability and low-carbon solutions, and perhaps most important, a culture and citizenry more engaged in the journey towards more sustainable and smarter cities. Of course this is a generalization: this series of regional ranking reports has demonstrated leadership from cities across the globe. But, as I wrote in our rankings of North America's smartest cities, our urban centers "demand 21st-century solutions to accommodate their growing populations in ways that not only maintain the quality of life, but also improve it. In short, smart cities are innovative cities." Without further ado, here is the top 10 smart cities for Europe in 2013 (and here's more about how we ranked them). 1: Copenhagen 2: Amsterdam Like Copenhagen the cycling rates here are off the charts. 5: Paris
BerryBoot – Du multiboot facile sur le Raspberry Pi J'aime beaucoup mon Raspberry Pi même si pour le moment, je n'en fais pas grand-chose (mais je vous prépare un article là dessus). L'une des limites de ce petit ordinateur, c'est qu'on stocke l'OS dans une carte SD. C'est cool, un poil artisanal (c'est ça qui est rigolo) mais si vous avez une petite carte SD, vous pouvez vite vous retrouver assez limité niveau distribs. Autre chose aussi, c'est le multiboot... Pas simple en terme de paramétrage et de stockage, de caler, disons 3, 4 ou 5 OS sur le même RaspBerry Pi . Et pourtant, c'est possible grâce à Berryboot, un soft/bootloader qui vous permettra de mettre plusieurs OS sur la même carte SD ou de les installer sur un disque externe ou une clé USB, histoire de continuer à utiliser votre petite carte SD. Pour installer Berryboot, téléchargez la dernière version ici, dézippez-le, puis placez son contenu sur une carte SD (formatée en FAT).

TOP 10 IMPOSSIBLE INVENTIONS THAT WORK « Revolutionizing Awareness Searl Effects Generator by Jeane Manning When Leonardo da Vinci sketched out an impossible invention, fifteenth-century scholars probably put him down. Forget it, Leon. Throughout history, experts tell innovators that their inventions are impossible. Perhaps in the 21st century the following inventions will be standard science, and a history student may wonder why 20th-century pundits disregarded them. This class of inventions could wipe out oil crises and help solve environmental problems. Forget the Rube Goldberg mechanical perpetual motion contraptions; they had to stop eventually. Inventors give various names to their space-energy converters. A spiritual commune in Switzerland had a tabletop free energy device running in greenhouses for years, but members feared that outsiders would turn the technology into weaponry. It may have been done before Tesla’s time. The garage inventors come from many backgrounds. One example is U.S. In 1923 Townsend T. 8.

Amazon Unveils Flying Delivery Drones on '60 Minutes' Amazon founder and CEO Jeff Bezos is known for making big bets in the world of innovation, and on Sunday night on 60 Minutes he revealed what might be one of his biggest: product delivery by flying robot drones. The service is called Amazon Prime Air and it's slated for rollout sometime in 2015, depending on FAA approval. A video of how the service will work has already been posted to YouTube, showing the process of the package being taken from the warehouse floor and on to the front steps of the customer’s home. Bezos was so excited about the news that he kept the details under wraps until just before the interview with the network began. Reacting to the unveiling of the Amazon-branded drone, Bezos interviewer Charlie Rose said, “I had no idea what its purpose was at first glance… They actually look like something out of a Philip K. You can watch the entire interview on the 60 Minutes website. BONUS: Drones vs. Have something to add to this story? Image: Amazon
Turn a Raspberry Pi Into an AirPlay Receiver for Streaming Music in Your Living Room I'm in the process of building a portable boombox using the Raspberry PI, while I have not assembled the case the individual pieces work as intended. The RaspPi will do one of three things on boot: connect to my home network, connect to a USB powered portable access point, or create an ad hoc network (ad hoc has had mixed results with iOS and Android devices). It will then start Shairport. Using a USB sound card it will output to a battery powered Lepai TA2020 amp and Dayton B652 speakers. The Rasp Pi and router are powered separately in its own case which will be Velcroed to the inside of the future case so I can remove it and connect it to a home stereo. The router and Rasp Pi get about 4 hours running off 4 Amazonbasic AAs. Credit to Lasse Christiansen for the boot up with ad hoc network write up: Flagged
