This biomedical device is going open source

This August, a team of researchers from FabLab Pisa and the University of Pisa’s Center for Bioengineering and Robotics will kick off an exciting new project known as OS4BME, or Open Source for Biomedical Engineering.

The project’s goal? Introducing the medical device world to a DIY & Makers philosophy. Indeed, OS4BME wants to help facilitate the development of simple, low-cost and high-impact biomedical devices such as neonatal baby monitors.

According to the official Arduino blog, the course is slated to take place at Kenyatta University (Nairobi) and will involve a number of staggered tracks, including configuring a 3D printing system, developing a neonatal monitoring device, using open source and designing solar-powered electronics based on the Atmel-powered Arduino platform.

“Participants will play an active role in the identification of components, design, assembling and testing of the device and in the discussion of regulatory issues in its development,” the Arduino blog explained. “Close attention will [especially] be paid to safety, ergonomic aspects and regulatory standards for biomedical devices.”

Arduino has announced its official support for the project, sending the research team a number of UNO boards, along with Wi-Fi and GSM shields to be used during the course. The components will subsequently be donated to the Kenyatta University and Fablab Nairobi.

OS4BME was created by Prof. Arti Ahluwalia (Univ. Pisa), Daniele Mazzei and Carmelo De Maria (Fablab Pisa, Centro E.Piaggio).

1:1 interview with Rob van Kranenburg (Part 2)

TV: What hardware principles help to ensure the transition proliferates for connected devices – yielding experience, efficiencies, and business profitability?

RvK: In the Special session on Planning Smart City of Japan in the 2012 IoT China, Shanghai Conference, Mine Shinshoro, director of Jetro Shanghai Office, recalls the 2010 disaster and explained that in the reconstruction of the cities the Japanese government will use the concept of smart communities to stabilize the energy power sources. Mr Masaki Yokoi (Nomura Research) takes up in the same discourse in his talk The social platform of the smart city, especially focusing on the change in mentality after the earthquake. Prior to that “we thought IT was King” he asserts,  however after the East Tokyo earthquake, industry, government and citizens come up with a different mind-set on what constitutes a smart citysmart-cities-japan

As infrastructure was totally destroyed, communication between regions was out, huge amounts of data were lost, over the past six months Japanese experts have reflected and brainstormed on the new nature of ICT. It still has a major role to play, but it must be a new role, especially in setting up more flexible resilient infrastructure, the regeneration process of communities, changing the layout of public services in society as a whole and inconsistent power supply and a more coherent business ecosystem.5 This describes the paradox that lies in the heart of IoT design. We want it to work seamlessly across all types and kinds of networks offering a constant and dependable flow to end-users wherever they are (home, car, abroad, indoors), without any visibility of the network nor hardware that is enabling this. It must run as smooth and invisible as possi4ble. The environment should become the interface.

Or, in the words of Mark Weiser: “Machines that fit the human environment, instead of forcing humans to enter theirs, will make using a computer as refreshing as taking a walk in the woods.”6 In our case, the end-users need not be human, but can be other machines. They too have needs in order to be themselves seamlessly tuned into a larger network. For them energy is the key issue. For us it could the breakdown described above caused by natural disasters, or for example in the case of Detroit it could be that the model that build the first iteration of such a seamless environment could go bust.

The key high level principles of the hardware architecture that will run sewage, mobility, energy, connectivity as well as appliances, devices and tools within the home and factories, is finding the perfect balance between optimizing convenience and enabling modding and hacking of any modular part. A recent study from Accenture shows “only 24% trust their utility to inform them of actions to optimize energy consumption – a decrease of 9% from 2012…. If given the choice, 73%… said they would consider alternative providers for purchasing electricity and alternative energy-related products and services.”7 This shows that designing trust into the system can only be done by allowing the largest and most varied group of stakeholders to list and add requirements to the architectures continuously.

TV: Describe the “data negotiation” in the network effect for Body Network, City Network, Smart Grids becoming deeply integrated?

RvK: Internet of Things is in its essence the seamless flow between:

  • BAN (body area network): the ambient hearing aide, the smart t-shirts
  • LAN (local area nework): the smart meter as a home interface
  • WAN (wide area network): the bike, car, train, bus, drones
  • VWAN (very wide area network): the ‘wise’ city as e-gov services everywhere no longer tied to physical locations
Connected Devices and the Seamless Flow of Data for IoT

Connected Devices and the Seamless Flow of Data for IoT

Whoever ensures trace-ability, sustainability and security linking up the gateways is de facto and de jure the new power. And would I want such a flow? The best possible feedback on my physical and mental health, the best possible deals based on real time monitoring for resource allocation, the best possible decision making based on real time data and information from open sources and the best possible alignments of my local providers with the global potential of wider communities.

In our architectures we are used to dealing with three groups of actors:

  • Citizens/end-users
  • Industry/SME
  • Governance/legal

These all are characterized by certain qualities, “a” for citizens, “e” for industry, and “o” for governance. In our current (Reference) Models and  (Reference) Architectures we build from and with these actors as entities in mind. The data flow of IoT will engender new entities consisting of different qualities taken from the former three groups. An example is the private grid operator, Frederic Larson is another:

“Twelve days per month Larson rents his Marin County home on website Airbnb for $100 a night, of which he nets $97. Four nights a week he transforms his Prius into a de facto taxi via the ride-sharing service Lyft, pocketing another $100 a night in the process. It isn’t glamorous-on nights that he rents out his house, he removes himself to one room that he’s cordoned off, and he showers at the gym-but in leveraging his hard assets into seamless income streams, he’s generating $3,000 a month. “I’ve got a product, which is what I share: my Prius and my house,” says Larson. “Those are my two sources of income.” He’s now looking at websites that can let him rent out some of his camera equipment.”8

TV: Take for example Smart Grids and Smart Energy. How does SEP 2.0 requirements shape the Utility and Energy Industry with Smart Meters integrating energy efficiency? Do you see solutions across the span of industry following a similar model?

RvK: I hope so.  It took two years for ZigBee, Wi-Fi and HomePlug “agreed to sit down and hash out a simplified yet IP-capable networking standard built on the foundation of ZigBee’s low-power home energy networking technology.”9 Cees Links, Founder and CEO of GreenPeak Technologies, writes on the Bosch blog on IoT “the wireless residential applications prosper best within the context of open communication standards, and offer OEMs the freedom to purchase from a large pool of suppliers and, most importantly, allow devices from different vendors to inter-operate, which is paramount in the market success of integrated Smart Home applications and will increase customer adoption when consumers can buy devices from different brands…One may think that WiFi and ZigBee are competing with each other. The reality, however, is that both technologies have their own place.”10

TV: What draws the importance in the work you do? How does it affect everyday people, developers, or EE designers? Is it vitally important for top-down influence to formulate the requirements across numerous verticals?

RvK: I must confess I am not a technical person at all. At home I am not even allowed to handle a hammer. I studied Languages and Literature because I like to read poetry and when I was younger aimed at as total as possible irrelevance to a world I thought and still think to be extremely badly governed, strangely tuned to scarcity as value (money, prestige, power) and unbalanced in the agency between humans, animals, things and the world at large. It is only when I grasped that with new forms of gaining influence and real power available at our feet for basically nothing, just your time and sober investment of energy: the internet and the web, it was actually possible to gain influence that I decided to fully devote myself to what is now called IoT from 2000 onwards.

I realized that IoT as it aims at individuating all objects on the planet, would effectively ‘be’ the new power as more and more resources would be linked together onto ever more stable platforms. That the next fight – that we see played out now – would be in trying to stabilize something that is in essence unstable; the internet as it was conceived as TCP/IP, or move the value chain as it is now in full to an Internet 2, a Quantum physics computing platform, for example the one build at CERN, or through research programs on Cyberphysical systems  in the US: “Cyber-physical systems (CPS) are engineered systems that are built from and depend upon the synergy of computational and physical components.  Emerging CPS will be coordinated, distributed, and connected, and must be robust and responsive.  The CPS of tomorrow will need to far exceed the systems of today in capability, adaptability, resiliency, safety, security, and usability.”11

The RK-1 is an Arduino-based mobile robot for iOS and Android

The RK-1 – designed by Evangelos Georgiou – is a WiFi-enabled robot that can be easily controlled on iOS and Android mobile devices using swipe gestures.

“I love building and programming mobile robots. Because of my love of mobile robots, mobile phones/tablets and the Arduino, I combined them to make a prototype called the ‘RK-1.’ [So] thank you to Arduino for an amazing open source microcontroller platform!” Georgiou wrote in a recent Kickstarter post.

“[Basically], the idea is to give the [open source] community the ability to make Arduino projects mobile. There is no end to what you can do – [adding] sensors and actuators to this fun little device and [controlling] it remotely.”

A full hardware breakdown for the RK-1 is as follows:

  • Programmable Arduino microcontroller
  • Wireless control over wifi
  • Dual H-bridge motor controller
  • LIPO battery (chargeable via a mini USB cable)
  • Acrylic base
  • Tank tracks and DC motors

“The free software to control the robot is available via Apple’s iTunes app store or Google play,” Georgiou noted. “It is [also] possible to read analog signals from devices (sensors) connected to the Arduino micro controller. [Plus], you can change the state of digital ports from high to low.”

Additional information about the RK-1 can be found on the robot’s official Kickstarter page.

The Internet of Things (IoT) is going to the dogs with Whistle

The Whistle Activity Monitor is an on-collar device that measures a dog’s activities including walks, play and rest. The device is designed to give canine parents a new perspective on day-to-day behavior and long-term health trends.

The Wifi and Bluetooth enabled Whistle allows users to check-in from their phones, share memorable moments and send detailed reports to a veterinarian. Basically, the device uses information including weight, age, breed and location to provide rich, individualized insights about a pe by precisely tracking activity trends over time.

“Whistle was inspired by my love of dogs,” co-founder and chief executive Ben Jacobs told the AFP. “We’re introducing a window into their lives; creating a way for owners and veterinarians to take a preventative approach to our pets’ health.”

According to Dr. Jeff Werber, a veterinarian at the Century Group in Los Angeles, there has always been a gap between what he can see in his office and what’s really going on with a dog.

“The thing is, animals act very differently behind closed doors, when they are alone, than they do around people, especially their owners. Often, an owner will notice a dog is limping. But when he examines the animal at his office, it walks normally. All the adrenaline and the desire to show off overcome the injury,” Werber told The Verge.

“By the time most owners see the problem, it has gotten quite acute. Dogs are very good at hiding the signs from owners. If you can see a change in activity or sleep, it makes it possible to spot problems sooner, and get them treated with less expensive, more preventative measures.”

As previously discussed on Bits & Pieces, the industry is beginning to see more electronic
devices – like the Whistle – join the growing ranks of Internet of Things (IoT) by becoming smart and connected.

To be sure, it is currently estimated that there are nearly 10 billion devices in the world connected to the Internet, a figure that is expected to triple when it hits approximately 30 billion devices by 2020. Clearly, the Internet of Things represents the greatest potential growth market for semiconductors and the embedded space over the next several years.

Atmel’s ATmega32u4 drives this mOwayduino robot

The mini mOwayDuino robot – powered by an Arduino Leonardo (ATmega32u4) board – is equipped with a wide range of sensors, including anti-collision, directional light intensity and opto-reflective infrared.

The little robot is also fitted with an RGB LED indicator, frontal LED, red rear LEDs, three-axis accelerometer, microphone, radio frequency module, a two-hour LiPo rechargeable battery and an SPI expansion kit.

In addition, the mOwayduino crew has designed a number of hardware add-ons, including a WiFi module that allows users to control the ‘bot via a mobile device or link with social network sites and email servers. Meanwhile, an optional camera streams real-time images to a PC, helping the mOwayduino learn how to recognize shapes or colors and respond to visual codes.

mowayduino

On the software side, the mOwayDuino robot can be programmed via Arduino’s IDE (Integrated Development Environment), as well as Java, Python and Scratch.

According to TechCrunch, the Indiegogo campaign to fund production of the ‘bot will kick off in less than two weeks.

“If we succeed, in three months, it will be on market. For people supporting the Indiegogo project, mOwayduino will be available at a special price,” a company rep told the publication. “If we exceed the money we need for the production, we will develop a graphical programming app for tablets.”

New Arduino Yún is based on Atmel’s ATMega32u4 microcontroller

Arduino’s Massimo Banzi has debuted the Yún at Silicon Valley Maker Faire 2013. The new board – designed in collaboration with Dog Hunter – is based on Atmel’s ATMega32u4 microcontroller and also features the Atheros AR9331, an SoC running Linino, a customized version of OpenWRT.

According to an Arduino rep, the Yún will make it easy for makers to connect to complex web services directly from Arduino.

“Historically, interfacing Arduino with complex web services has been quite a challenge due to the limited memory available. [Plus], they tend to use verbose text based formats like XML that require quite a lot or RAM to parse,” the rep explained in a blog post.

“On the Arduino Yún we have created the Bridge library which delegates all network connections and processing of HTTP transactions to the Linux machine.”

Essentially, the Yún can best be described as a combination of the classic Arduino Leonardo (based on Atmel’s Atmega32U4 processor) with a WiFi system-on-a-chip running Linino (a MIPS GNU/Linux based on OpenWRT). Like a Leonardo, the board boasts 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. The Wi-Fi enabled Yún is equipped with a standard-A type USB and a micro-SD card plug for additional storage.

As expected, the Yún ATMega32u4 can be programmed as a standard Arduino board by linking it to a PC with the micro USB connector – and can also be programmed via WiFi as well as reached with SSH.

“Using the Bridge library in your sketches, you can link the 32u4 to Linux, launching programs and scripts, passing them parameters (sensor readings for example) and reading their output, thus creating a strong integration between the creativity of your sketch and the power of Linux.The Yún supports Shell and Python scripts out-of-the-box but you can install a wide range of open source software and tools,” the rep continued.

“To make it even simpler to create complex applications we’ve partnered with Temboo which provides normalized access to 100+ APIs from a single point of contact allowing developers to mix and match data coming from multiple platforms, [including] Twitter, Facebook, Foursquare and even FedEx or PayPal.”

The Arduino Yún will be available at the end of June at a $69 price point.

Atmel-powered Lumapad is an open-source LED project

The Lumapad can best be described as an open source, high intensity, 8000 lumen LED lighting system built around a user-programmable Arduino (Atmel) compatible micro-controller and an (optional) electric IMP.

According to project designer Richard Haberkern, 32 ultra-bright LEDs are positioned in a landscape array to provide bright, even and controllable lighting, drawing only 88 watts. Meanwhile, a built in electronic dimmer makes the light intensity adjustable to fit just about any environment.

“This is no ordinary bright light,” Haberkern explained. “With your own custom software, you can control the light intensity, flash effects and even the color temperature via your iPhone, Android device or any computer with an internet connection. An Arduino compatible controller along with the newly available Electric IMP WiFi SD card are both built in, [so you can] control the Lumapad any way you can imagine.”

As noted above, the Lumapad is powered by an Arduino compatible ATmega 328P micro- computer and is pin-for-pin compatible with most open source Arduino boards on the market. The ATmega328P – an 8-bit AVR RISC-based microcontroller – combines 32KB ISP flash memory with read-while-write capabilities, 1024B EEPROM, 2KB SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible timer/counters with compare modes, as well as internal and external interrupts.

Additional specs include a serial programmable USART, a byte-oriented 2-wire serial interface, SPI serial port, a 6-channel 10-bit A/D converter (8-channels in TQFP and QFN/MLF packages), programmable watchdog timer with internal oscillator, and five software selectable power saving modes. By executing powerful instructions in a single clock cycle, the ATmega achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.

On the software side, developing for the IMP is unlike your typical embedded development environment, as there are no SDKs to install, JTAG pods, or long download time. Rather, you develop your code in a browser-based IDE, compile it and run on the IMP in under a second. And, using the Arduino compatible micro-computer, you can write multiple programs to control a scene or room lighting.

The Arduino-powered Lumapad has already reached its funding goals on Kickstarter, with 225 backers and $94,482 pledged. Additional information can be found here on Kickstarter, or the official Lumapad website.

A Pocket-Sized, Low-Power Ecosystem Makes Wi-Fi Easy

By Ingolf Leidert

Sensor networks are nothing brand new and even terms like “smart dust” have been around for a while. Many have envisioned a future where every technical entity around us will be “smart” in some way and is permanently connected to a huge network consisting of small sensors that help monitor and control our world. Usually, the large step into such a future vision is divided into several smaller steps. Obviously, one parameter seems to be essential for the small and smart sensors vision: the power consumption of such an entity. With the ATmegaRF SoC family, Atmel has introduced one of the lowest power IEEE 802.15.4 systems in the world. Its low power consumption combined with the full AVR microcontroller (MCU) capabilities makes networks built with lots of compact, low-power wireless sensors look more realistic now. One project that shows this perfectly is the Pinoccio.

Pinoccio is an open-source, crowd-funded solution that provides a complete ecosystem for building products supporting The Internet of Things. These small “scout” boards, compatible with the Arduino platform, come with everything a “smart, wireless, connected entity” would need:

  • LiPo battery (chargeable over USB)
  • LED
  • Temperature sensor
  • Antenna
  • Several I/Os for connecting DIY hardware (like more sensors)
  • And, as its “heart”, the Atmel ATmega128RFA1 with its excellent power consumption of less than 17mA when actively transmitting. The ATmega128RFA1 is pin-compatible with the new ATmegaRFR2 family…so perhaps we’ll see future “scout” boards in 64kB or 256kB versions. 

The developers have chosen that MCU explicitly for its low power and RF capabilities. And, as you can see from the estimated power specs, a sleeping scout board should be able to run for more than a year from one battery charge. Because the whole Pinoccio ecosystem includes a Wi-Fi board that finally connects all the tiny “scout” boards to an existing Wi-Fi infrastructure and even offers SD card data storage, this whole system looks like a wonderful first step into The Internet of  Things.

Atmel + Celeno = Wi-Fi Direct Remote Controls

Atmel and Celeno Communications, a leading provider of high-performance Wi-Fi chips and software, are working together to develop integrated solutions for high-performance Wi-Fi Direct remote controls for next-generation set-top box and video gateway platforms.

Based on Celeno’s Wi-Fi chipset and Atmel’s ultra-low power Wi-Fi Direct technology, the resulting solution will help wireless designers bring their products to market faster. They’ll also be able to lower overall system costs and power consumption. The new set-top box platform will be demonstrated at 2013 CES.

Wi-Fi Direct allows Wi-Fi devices to securely connect and communicate without a wireless access point, essentially simplifying and speeding the connection process. Say you have an image on your smartphone that you want to print, or you want to transmit video from your phone to your TV. Using Wi-Fi Direct technology, these devices can automatically find each other and complete the tasks–without needing a wireless router, or a hotspot, or SSIDs. In this era of The Internet of Things, when web-enabled devices are expected to outnumber people on our planet, Wi-Fi Direct represents a key enabler.

With a broad product portfolio including AVR and ARM-processor based microcontrollers, touch technologies and Wi-Fi solutions, Atmel is right at the heart of the devices fueling The Internet of Things. Atmel recently strengthened our position in this area with our acquistion of Ozmo, Inc., a leading provider of ultra-low power Wi-Fi solutions. From our expanded portfolio, developers can find the technologies they need to create smart, connected products that are targeted to The Internet of Things.
