The Arduino Yún (Yún means "cloud" in Chinese.)

Arduino

At today’s Bay Area Maker Fair, Arduino announced its newest board—the Arduino Yún. The board is an Arduino Leonardo running Linino, a Linux fork based on OpenWRT. The board is Wi-Fi capable, which Arduino hopes will encourage people to use the boards to make cloud-ready projects.

In an official statement the company explained: “Historically, interfacing Arduino with complex Web services has been quite a challenge due to the limited memory available. Web services tend to use verbose text-based formats like XML that require quite a lot or ram to parse. On the Arduino Yún we have created the Bridge library which delegates all network connections and processing of HTTP transactions to the Linux machine.”

Earlier this week, another company called Spark Devices launched a similar idea on Kickstarter called Spark Core. That initiative puts forward a Wi-Fi capable board for Arduino projects that permits wireless programming and the ability to interface with Web services. The company originally asked for $10,000 and has since raised more than $300,000. (The campaign ends June 1.)

The Arduino Due.

Arduino

Raspberry Pi has received the lion's share of attention devoted to cheap, single-board computers in the past year. But long before the Pi was a gleam in its creators' eyes, there was the Arduino.

Unveiled in 2005, Arduino boards don't have the CPU horsepower of a Raspberry Pi. They don't run a full PC operating system either. Arduino isn't obsolete, though—in fact, its plethora of connectivity options makes it the better choice for many electronics projects.

While the Pi has 26 GPIO (general purpose input/output) pins that can be programmed to do various tasks, the Arduino DUE (the latest Arduino released in October 2012) has 54 digital I/O pins, 12 analog input pins, and two analog output pins. Among those 54 digital I/O pins, 12 provide pulse-width modulation (PWM) output.

waderoush writes "If you visit Menlo Park, CA-based Willow Garage, you'll meet a $400,000 humanoid robot called PR2 that has stereo vision, a pair of dextrous arms, and enough smarts to roam the building indepedently and even plug itself into the wall when it needs to recharge. But in a sense, PR2 is just a demo. The real action at Willow Garage is around ROS, the Robot Operating System, a free meta-operating system that's already being used by hundreds of roboticists around the world and may soon be handed over to an independent foundation analogous to the Apache Software Foundation. Brian Gerkey, Willow Garage's head of open source development, says 'What we need is a LAMP stack for robotics,' and hopes that ROS will jumpstart innovation in robotics in the same way Linux and other free software components provided the foundation for the Internet boom. Today's roboticists 'have to come at the problem with a very deep expertise in all aspects of robotics, from state estimation to planning to perception, which automatically limits the number of people capable of building new things,' Gerkey says. 'But by providing a basic toolset analogous to the LAMP stack, we can get to a point where all you need to know is how to write code and what you want your robot to do.'"

First time accepted submitter paysonwelch writes "I am a developer and entrepreneur and I am considering developing a very graphically rich and custom interface for my latest application which does charting and analysis of large data sets. The application would feature lots of gauges, knobs and levers. As I was thinking about this I said to myself, why not hook up physical knobs and levers to my computer to control my application instead of designing them in 2D bitmaps? This could potentially save screen space and provide tactile feedback, and a new way of interacting digitally with one's application and data. So my question is whether or not anyone out there has advice for building a custom solution, perhaps starting with a mixing board, or if there are any pre-fab kits / controllers for achieving this?"

From behind the long-gone, so-called “iron curtain,” nearly-lost musical innovation is beginning to become available. But perhaps more than any geo-political change, the power of an Internet-based community hungry to share knowledge is making national borders that once isolated information melt away.

Earlier this week, I shared reflections I wrote up for Amsterdam’s STEIM on the significant of DIY Music. But one group of artists, the Standuino team from Brno, Czech Republic, really exemplified that spirit. First off, their hardware is utterly brilliant and eminently practical, an Arduino-based platform on which they’ve made it easy to create and modify designs, and share useful tools like the sampler they demonstrated for us in Amsterdam. Secondly, they’re international – the performance brought together a Brazilian, Czech, and Dutch artist in their presentation. Third, they took “DIY” straight to the transportation, hitchhiking all the way from Brno to Amsterdam to be part of our performance, for which we’re all incredibly grateful!

The Standuino crew emphasize that they also wish to make the innovation of the Czech people more visible to the rest of the world. You know Bob Moog or Morton Subotnick, for instance, but do you know the name Standa Filip?

You should. The maker of extensive DIY instruments, interactive work, robotic installations, and new media, Standa (hence Standuino) is inspiring a new generation of artists – first in the Czech Republic, eventually in the world. Those artists, led by Standuino, are recreating some of his work, as well as making new work that carries on his spirit.

Check out the videos here to see him talk about his history and play his instruments, then learn more – and find the Arduino-based hardware designs, which I’ll cover more next week – at the Standuino site:

But there you go – from Rio to Singapore, once I hit publish, just about anybody can learn what it was like to be a lone DIYer in Communist Czechoslovakia – then go find open source ideas with which they can make music from the new generation of creators in the Czech Republic, in a matter of seconds.

Yeah, we overhype the Internet. But that’s pretty damned awesome. I’m going out in the sunshine now for a bit, because that’s awesome, too, but I’m pretty happy that I get to make this my day job. And thanks to you for making that possible, because with you as a reader, none of this would be true.

The book presents an international spectrum of interdisciplinary projects at the intersection of laboratory, trade show, and urban space that play with the new frontiers of perception, interaction, and staging created by current technology. The work reveals how technology is fundamentally changing and expanding strategies for the targeted use of architecture, art, communication, and design for the future continue
