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.

Behavio_hud_large

Google has added a few more employees to its roster. The new hires come from the team behind Behavio, a company works on recording and analyzing the data that smartphones are capable of keeping track of: location, speed, nearby devices and networks, phone activity, noise levels, and much more. The idea is that the software can keep track of all of this data and be able to watch for any deviant behavior — and make educated guesses based on what's going on. To do all of this, Behavio created Funf, an open source framework that allows developers to leverage this data on Android.

The team is made up of three MIT Media Lab alums, and last year the project won a $355,000 Knight News Challenge grant. As reported by Nieman Journalism Lab,...

Dsc_7645_large

If you've spent any time flipping gadgets, you've probably noticed that they're much easier to buy than to sell. One can buy a used iPhone from half-a-dozen places at this point, often with no more than a few clicks — but try to sell one, and you're stuck with either eBay or a hodgepodge of forums and mini-marketplaces.

A new iOS app, launching today, claims to fix that, offering a streamlined path from listing to payment. It's called Sold, and it serves as photographer, broker and banker for each item, finding a price and a seller for you automatically, and collecting its fee from arbitrage. If the system works, all you'll have to do is snap a few pictures and pack a single box — as long as you're willing to let Sold set the price...

TEDxPioneerValley - Jay Silver - Makey Makey & The Maker's Mindset

Jay Silver, a research assistant and Ph.D. candidate in Media Arts and Sciences in the MIT Media Lab's Lifelong Kindergarten Group, demonstrates a new technology called Makey Makey that turns the whole world into a computer mouse. He says of its genesis: "There I am, at an UnSchooling Camp, running a workshop, and a teen makes a musical looper out of an ordinary hula-hoop. Who would think of a hula-hoop as a music controller? This is the mindset of Makers. And watch out, because the Maker Movement is coming, and it's dangerous to existing paradigms of education and industrial production! What tools will the Makers use? AboutTEDx x = independently organized event In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized. (Subject to certain rules and regulations.)

TEDxSantaCruz: David Merrill - Sifteo Cubes, Makers and Learners: My Double Ah-Ha Moment

This presentation presents an update to David Merrill's 2009 TED talk which you can view at: www.ted.com David Merrill is co-founder and president of Sifteo, a company based in San Francisco building the future of play. Sifteo's first product is a tabletop user interface system made of wireless graphical tiles that enables unique intelligent play applications. David is a graduate of the Fluid Interfaces Group at the MIT Media Lab. His work explores how human interactions with computers can leave the limitations of the desktop interface behind, through the development of physical-digital tools that operate comfortably in our real-world environments. He has lectured in computer science at Stanford University and led music controller design workshops at the MIT Media Lab. David holds a MS in Computer Science and BS in Symbolic Systems from Stanford University, and a MS and Ph.D. from the MIT Media Lab. ThisTEDxSantaCruz talk is part of over 2 dozen surrounding our theme of "Engage!" This inaugural TEDxSantaCruz event was held June 11, 2011 at the Cabrillo College Music Recital Hall in Aptos, CA (Santa Cruz County). www.tedxsantacruz.org TEDx. x=independently organized TED event.

TEDxNewEngland | 11/01/11 | Mozart & Me - A Radical New Model of Interskill Collaboration

The new movie "Anonymous" shows that our culture is more obsessed than ever with celebrity and genius, and that we look for transcendent heroes capable of leading us through the darkness. On the other end, masses of people meet online as "friends" to share intimacies or to solve problems collectively. The truth is that the real power of invention lies in between these two extremes, where experts can collaborate as equals with everyone else, combining unique and broad perspectives for the benefit of all. Music provides an ideal test bed for this new mode of collaboration. Tod's group at the MIT Media Lab has spent the last 25 years developing technologies to enhance the musical expression of virtuosi like Yo-Yo Ma, to open the expressive and creative musical potential for amateurs, children and the infirm, and to breakdown barriers between artist and audience. We are now entering a bold new phase of inter-skill collaboration, informed by the recent successes of Guitar Hero, Björk's Biophilia, and RjDj's mobile music apps. Through physical composing, sequenced sonic objects, morphing Mozart-to-merengue, and creating City Symphonies and Personal Operas, we believe that a more satisfying musical ecology can be forged which -- in turn -- will be a powerful inspiration for a more creative society.

Sensor Fusion on Android Devices: A Revolution in Motion Processing

Google Tech Talk August 2, 2010 ABSTRACT Presented by David Sachs. Gyroscopes, accelerometers, and compasses are increasingly prevalent in mainstream consumer electronics. Applications of these sensors include user interface, augmented reality, gaming, image stabilization, and navigation. This talk will demonstrate how all three sensor types work separately and in conjunction on a modified Android handset running a modified sensor API, then explain how algorithms are used to enable a multitude of applications. Application developers who wish to make sense of rotational motion must master Euler angles, rotation matrices, and quaternions. Under the hood, sensor fusion algorithms must be used in order to create responsive, accurate, and low noise descriptions of motion. Reducing sensing errors involves compensating for temperature changes, magnetic disturbances, and sharp accelerations. Some of these algorithms must run at a very high rate and with very precise timing, which makes them difficult to implement within low-power real-time operating systems. Within Android specifically, this involves modifying the sensor manager, introducing new APIs, and partitioning motion processing tasks. David Sachs began developing motion processing systems as a graduate student at the MIT Media Lab. His research there led him to InvenSense, where he continues this work with MEMS inertial sensors used in products such as the Nintendo Wii Motion Plus. David's designs incorporate gyroscopes <b>...</b>
