Massimo Banzi announced it some minutes ago during his annual “The state of Arduino” presentation at Maker Faire Bay Area: Arduino Yún is the first of a revolutionary family of wifi products combining Arduino with Linux.
Yún means “cloud” in chinese language, as the purpose of this board to make it simple to connect to complex web services directly from Arduino.
Designed in collaboration with Dog Hunter, a company with extensive experience with Linux, the board adopts the Linino distribution which provides signed packages to ensure the authenticity of the software installed on the device.
Historically, interfacing Arduino with complex web services has been quite a challenge due to the limited memory available and they 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.
Arduino Yún is the combination of a classic Arduino Leonardo (based on the Atmega32U4 processor) with a Wifi system-on-a-chip running Linino (a MIPS GNU/Linux based on OpenWRT). It’s based on the ATMega32u4 microcontroller and on the Atheros AR9331, a system on a chip running Linino, a customized version of OpenWRT, the most used Linux distribution for embedded devices.
Like a Leonardo, it has 14 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator and a micro USB connector.

We know the human tongue is extremely sensitive. Go ahead: touch something with your tongue. There isn’t a naked surface on your body that’s better equipped for sheer sensation. There’s nothing more plastic, built to adapt and optimize itself for new experiences. Not only is your tongue fully equipped with a sense-optimized surface, but anything you experience on your tongue gets mainlined directly into your brain. So if we’re serious about hacking the body to provide new kinds of sense experiences, forget about the fingertips. Forget anything on the outside of the skull. The answer is obvious: trick out your tongue.
The Tongueduino is the brainchild of MIT Media Lab’s Gershon Dublon. It’s a three by three electrode pad that rests on your tongue, runs through an Arduino controller, and connects to one of several environmental sensors. Each sensor might register electromagnetic fields, visual data, sound, ambient movement — anything that can be converted into an electronic signal. In principle, this could allow blind or deaf users to “see” or “hear” with their tongues, or augment the body with extrahuman senses.
Dublon, an electric engineer by training, studies how “sensor networks might become extensions of our nervous systems — networks of remote, distributed sensing prosthetics.” He has been experimenting with his Tongueduino himself for the past year and is now beginning training with a group of twelve volunteers. “Through Tongueduino, we hope to bring electro-tactile sensory substitution beyond the discourse of vision replacement, towards open-ended sensory augmentation that anyone can access,” he writes.

The idea behind the Raspberry Pi to Arduino shields connection bridge is to allow to use any of the shields, boards and modules designed for Arduino in Raspberry Pi. It includes also the possibility of connecting digital and analog sensors, using the same pinout of Arduino but with the power and capabilities of Raspberry.
In order to make complete the compatibility we have created the arduPi library which allows to use Raspberry with the same code used in Arduino. To do so, we have implemented conversion functions so that you can control in the same way as in Arduino all the I/O interfaces: i2C, SPI, UART, analog, digital, in Raspberry Pi.
Let’s summarize what we can do using this shield along with the arduPi library:
- Connect any Arduino Wireless module in Raspberry. Some examples: XBee 802.15.4/XBee ZigBee, RFID, NFC, Bluetooth, Bluetooth Pro, Wifi, GPRS, 3G
- Connect any sensor (analog 0-5V, digital) to Raspberry Pi with a precession of 16b using the ADC integrated. Connect also complex sensors through i2C and UART buses
- Connect any Arduino specific shield such as: Radiation sensor shield, CanBus, Relay shield,…
- Connect any electronic module or actuator which works over i2C, SPI, UART

Arduino is probably the world’s most popular open source physical computing platform. The little microcontrollers show up in everything from wild art projects to serious home automation efforts. It’s great and all, but couldn’t it be … smaller? Electrical engineer Ken Burns thought so, and got to work on the TinyDuino.
TinyDuino is a fully Arduino-compatible hardware platform, complete with expansion shields (add-on boards that have specific sensors or lights, for you non-robot designers). But where an Arduino Uno is around the size of a credit card, the TinyDuino is smaller than a quarter, and its sibling the TinyLily is the size of a dime. The TinyDuino line is designed around three core elements: size, affordability, and expandability. The idea, says Burns, is to open up Arduino to a whole host of applications that simply aren’t possible with the larger board.
The seeds of TinyDuino were planted when Burns was working on creating smart sensors. The goal was sensors that would be plug and play, with on-board intelligence that allowed them to handle all the hard stuff, like reading data, calibration, and formatting the output. “For a typical hobbyist, this would mean you could just plug in any sensor, whether it’s temperature, pressure, light–whatever, and your system would read it out and know what it was and the units it was in.”
Burns says that Arduino was a natural fit as a basis for the work. When he shared his progress with friends and members of the SYN/HAK hackerspace, “it became pretty apparent that there were others that were very interested in having very tiny Arduino compatible processor modules,” Burns says. Focus switched over to designing a family around this core concept.
The TinyDuino is an exercise in design extremes. When you start cutting a hardware board down to the size of pocket change, it forces you to make a lot of serious decisions about what features are needed. In order to cut the TinyDuino down to size, Burns says, they moved a lot of the default affordances of the Arduino hardware, like the USB connector, on to TinyShields. (A similarly-shrunken Arduino project, the Digispark, has the USB plug built in, similar to a small thumbdrive ). TinyShields are an intensification of the shield paradigm that is already an important part of Arduino hardware.
“If you look at the board itself,” says Burns, “it’s really just a core processor that brings out signals to pins.” Ordinarily, those pins need to be attached (often through soldering) to electronics that can process the signals and turn them into motion, light, sound, WiFi, etc.
The Supsi Summer School (Ticino) organizes for next july (23rd to 27th) a workshop on prototyping open-source fashion with Massimo Banzi. You can find the complete description below and apply to the course at this link.
Physical computing encompasses the design of interactive physical systems through the use of software and hardware that can sense and respond to the analog world. Applications of physical computing are becoming spread and, thanks to technology miniaturization and fast prototyping, it is now possible to experiment solutions of interactive and wearable objects that can be digitally fabricated.
Goal of the workshop is the design and prototyping, through the Arduino platform, of objects that sense, interpret and react to the real world and that can be wearable and digitally fabricated.
During the first phase of the workshop, notions of physical and wearable computing will be provided together with an introduction to the Arduino platform and to digital fabrication techniques.
In the second phase, workshop activities are split in two different tracks:
- the physical computing track, held by Massimo Banzi, will focus on the design and prototyping of digitally fabricated interactive objects.
- the wearable computing track, held by Zoe Romano, will explore the world of digital fabrication applied to open source fashion and, in particular, to the implementation of digitally fabricated accessories featured by interactive behaviors.
The workshop requires some rudimentary understanding of programming that can be acquired in the previous week (Typography, computation and fabrication). Applicants without previous experience are warmly welcome to contact us for getting a list of books for reference

Open-source hardware has seen a number of exciting development over the past few years: the open hardware summit, the open-source hardware definition, an open-source hardware logo, and, of course, lots of great new open-source hardware products. Many of the people behind these efforts have been working together to establish an lasting framework for the promotion of open-source hardware and the coordination of these kinds of community initiatives. I’m very happy to share the news that this initiative has found a home in the newly-announced Open-Source Hardware Association (OSHWA).
The founding board consists of Alicia Gibb, co-founder of the Open Hardware Summit and former employee of Bug Labs; Nathan Seidle, founder and CEO of SparkFun Electronics; Windell Oskay, co-founder of Evil Mad Scientist Laboratories; Danese Cooper, a long-time advocate of open-source; Wendy Seltzer, a lawyer and expert in free software and free speech; and Catarina Mota, PhD researcher and co-organizer of this year’s Open Hardware Summit.
The association was set up and the initial board members selected by a working group which also included myself, Tom Igoe, and Massimo Banzi (of Arduino); Ayah Bdeir, co-founder of the Open Hardware Summit, founder of littlebits, and instigator of many of the above community initiatives; and many others (listed in the OSHWA FAQ). These folks have been much of the driving force behind the open-source hardware summit, definition, and logo and I’m thrilled to see the energy from these efforts being translated into a more lasting form. Additional board members will be elected soon, from public nominations.
This is a very exciting time for open-source hardware and I think the establishment of the association is an important step in maintaing and developing a vibrant open-source hardware community.

The new 3G shield for Arduino enables the connectivity to high speed WCDMA and HSPA cellular networks in order to make possible the creation of the next level of worldwide interactivity projects inside the new Internet of Things era. The module counts also with an internal GPS what enables the location of the device outdoors and indoors combining standard NMEA frames with mobile cell ID triangulation using both assisted-mobile (A-GPS) and mobile-based (S-GPS) modes. Other interesting accessories which can be connected to the module are a video camera which enables the record of video in high resolution (640×480), an audio kit including microphone, speaker, hands free and headphones sets and a SD socket to save directly all the data coming from the 3G network or recorded from the video camera.
