FizzJelly with Atmel and the IoT

The Mobile Minds crew has debuted an Atmel-powered cellular connected platform designed to track and monitor a wide range of sensors. FizzJelly works straight out of the box, allowing users to effortlessly monitor and control their IoT devices.

“From motion to temperature and from water leaks to GPS tracking, [FizzJelly] will let you know by sending an alert,” a Mobile Minds rep explained in a recent Kickstarter post.

“It makes it easy to check to see if anyone has been in your house, find out where your car is, if your rooms have got too hot or cold or even turn on and off the lights.”

Indeed, users can command and query FizzJelly simply by sending and receiving text messages with a cell phone. To be sure, configuring and using FizzJelly is extremely simple, requiring a regular SIM card, a connected sensor and a text message. As expected, each unit can be configured with a unique PIN code to secure it against unauthorized access.

Additional key specs and features include:

  • Atmel ATmega32U4 MCU (microcontroller)
  • One internal temperature sensor
  • 8 I/O ports
  • One expansion port
  • GPS module (optional)
  • Programmable over Micro-USB
  • GSM Quad Band – 850/900/1800/1900MHz
  • Open Source development kit
  • Power range 6v – 16v (Motion Detector requires 9v – 16v)
  • Either Battery or AC adapter
  • CE & FCC approved
  • GCF (Worldwide approved module)
  • PTCRB (North America approved module)

Interacting with the Atmel-powered morphing table

Last week, Bits & Pieces reported that MIT researchers had created a morphing table with Atmel microcontrollers (MCUs) under the hood. Today, we’ll be taking a closer look at the platform’s interactive features.

Dubbed inFORM: Dynamic Physical Affordances and Constraints through Shape and Object Actuation, the Atmel-powered table is equipped with a number of ATMega2560s, along with 900 individually actuated white polystyrene pins that make up the surface in an array of 30 x 30 pixels.

An overhead projector provides visual guidance of the system, with each pin capable of actuating 100mm and exerting a force of up to 1.08 Newtons each. Actuation is achieved via push-pull rods that are utilized to maximize the dense pin arrangement – making the display independent of the size of the actuators.

MIT’s latest configuration of the morphing table features two separate interfaces – adding a display so viewers can observe the individual who is manipulating the surface. As HackADay’s James Hobson notes, MIT’s advanced platform opens up a whole new realm of possibilities for the tactile digital experience.

“The inFORM also has a projector shining on the surface, which allows the objects shown from the other side to be both visually and physically seen — they use an example of opening a book and displaying its pages on the surface,” he explained.

“To track the hand movements they use a plain old Microsoft Kinect, which works extremely well. They also show off the table as a standalone unit, an interactive table. Now all they need to do is make the pixels smaller.”

These robots make music

Steven Kemper studied music composition and computer technology at the University of Virginia. Unsurprisingly, he was always fascinated with robotic instruments that can be programmed to play music, respond to human musicians and even improvise.

So Kemper, along with colleagues Scott Barton and Troy Rogers, went on to found Expressive Machines Musical Instrument (EMMI), designing a Poly-tangent Automatic (multi)Monochord, also known as “PAM.”

As TechNewsWorld’s Vivian Wagner notes, the stringed instrument’s pitches are controlled by tangents – the equivalent of fingers – each of which is driven by a solenoid. Messages are sent from a computer via a USB to an [Atmel-powered] Arduino board, which switches the solenoids on and off.

PAM is also capable of receiving data from musical and gestural input devices – such as a MIDI keyboard, joystick or mouse – or from environmental sensors, allowing the platform to improvise its own music based on the programmer’s parameters and instructions.

“These instruments are not superior to human performers,” Kemper, now an assistant professor of music technology at Rutgers University, told TechNewsWorld. “They just provide some different possibilities.”

In addition to PAM, EMMI has created a variety of instruments, all of which can be programmed to play in multiple genres and settings.

“These instruments can improvise based on structures we determine or by listening to what performers are playing,” Kemper added. “We work with the free improv aesthetic and [our instruments] don’t fit into a particular musical genre. It’s improvising based on any decisions the performers make.”

The Smithsonian is going 3D

The Smithsonian has unveiled its X 3D Collection along with a new 3-D explorer in an effort to make museum collections and scientific specimens easier for the public to access and study. 

According to Günter Waibel, director of the Institution’s Digitization Program Office, the Smithsonian X 3D explorer and initial collection of scanned objects are the first step in showcasing how 3D technology is capable of transforming the work of the Smithsonian, as well as other museums and research institutions.

More specifically, the above-mentioned X 3D Collection features objects from the Smithsonian that highlight different applications of 3D capture and printing, along with digital delivery methods for 3D data in research, education and conservation including:

  • The Wright Flyer (National Air and Space Museum): The 3D scan of the Wright Flyer allows users to explore the fine details of the artifact, providing a window into the Wright’s inventive genius and understanding of the principles of flight.
  • Cassiopeia A Supernova Remnant (Smithsonian Astrophysical Observatory): This multi-wavelength 3D reconstruction of Cassiopeia A uses X-ray data from NASA’s Chandra X-ray Observatory, infrared data from NASA’s Spitzer Space Telescope and optical data from NOAO’s 4-meter telescope at Kitt Peak and the Michigan-Dartmouth-MIT 2.4-meter telescope.
  • Fossil Whale (National Museum of Natural History): Smithsonian paleontologists and 3D staff conducted a time-sensitive documentation of the skeletons from the site (Chile) and captured essential data about the arrangement and condition of the skeletons before they were removed and the site was paved over.
  • Cosmic Buddha (Freer and Sackler galleries): To study such low-relief compositions, scholars have traditionally made rubbings with black ink on white paper, which give stronger contrast to the outlines. 3D scanning, used with a wide variety of imaging techniques, can give even more clarity to the designs.

To view these and other objects scanned using 3D technology, the Smithsonian and San Francisco-based Autodesk created the Smithsonian X 3D explorer which allows users to easily rotate models, take accurate measurements between points and adjust color and lighting. The explorer is also equipped with a storytelling feature, enabling Smithsonian curators and educators to create guided tours of the models.

In addition to viewing objects using the explorer, the raw 3D data itself will be made available for downloading and printing, both for personal and noncommercial use. Teachers and other educators can use the data to create realistic 3D models of these objects for use in the classroom.

It should be noted that additional support for the Smithsonian’s 3D efforts was provided by 3D Systems, which helped scan, design and print objects from several Smithsonian museums, including one of the large fossilized whales found in Chile’s Atacama Desert.

Atmel debuts new low-power 8-bit tinyAVR MCUs

Atmel has expanded its low-power 8-bit tinyAVR family with the addition of the ATtiny441 and ATtiny841. As we’ve previously discussed on Bits & Pieces, the 8-bit AVR MCUs are ideal for cost-effective consumer applications such as computer accessories, thermostats, personal health accessories and a wide range of Maker projects.

atmelnewattiny

According to Atmel’s Director of Flash-based MCUs Ingar Fredriksen, the new ATtiny 441/841 MCUs boast higher system integration with intuitive tools and peripherals to help facilitate optimized performance with lower power consumption. Indeed, the ultra-low power 14-pin tinyAVR MCUs deliver enhanced analog and communication capabilities for an overall lower system cost in a smaller package.

“Atmel has been the 8-bit MCU leader for more than a decade and continues to think beyond the core, enabling our customers to differentiate their end products,” said Fredriksen. “Our AVRs have been popular since its inception and continue to be the MCU of choice both for professional engineers in consumer and industrial applications and among our 300,000 members in the AVR Freaks community consisting of engineers, hobbyists and Makers.”

As Fredriksen notes, the ATtiny441/841 devices are powerful MCUs packaged in a small form factor. More specifically, the new ATtiny441 and ATtiny841 MCUs feature an uber-mini 3×3 QFN package and 4 and 8KB of Flash memory, respectively.

“The new devices offer enhanced analog performance, including an ADC with calibrated multilevel internal analog reference, with 12 ADC channels on a 14-pin device, two independent USARTs with wake-up from power down without data loss, SPI interface and an I2C slave interface for enhanced communication capabilities,” Fredriksen continued. “In addition, the devices feature flexible clocking options, including a ± 2% internal oscillator with fast wake-up, which allows the UARTs to communicate without the need of an external crystal and wake-up from sleep without data loss.”

As expected, the ATtiny441/841 devices are fully supported by Atmel Studio 6, the integrated development platform (IDP) for developing and debugging Atmel ARM Cortex-M and Atmel AVR MCU-based applications. Simply put, Atmel Studio 6 IDP offers devs a seamless, easy-to-use environment to write, build, simulate, program and debug applications written in C/C++ or assembly code using the integrated GCC compiler and AVR assembler. AS6 also provides easy access to the online Atmel Gallery apps store and Atmel Spaces, a cloud-based collaborative development workspace allowing the designer to host software and hardware projects targeting Atmel MCUs.

To help accelerate devs and Makers accelerate ATtiny441/841 AVR MCU designs, the new devices are supported by Atmel’s AVR Dragon Board which can be snapped up at the Atmel Online Store for USD $49. The ATtiny841 and ATtiny441 are also supported by the STK600, AVRONE, JTAGICE mkII, JTAGICE3 and AVRISPmkII development tools.

The ATtiny441/841 is currently available in mass production, with samples that can be ordered here. Readers who are Maker interested in testing their creativity with AVR MCUs (including the new ATtiny441/841 AVR MCUs) may want to check out Atmel’s very own Master Maker Design Contest here.

First desktop wire bender hits Kickstarter

The first desktop CNC wire bender has hit Kickstarter with an Atmel MCU (ATxmega192/TinyG) under the hood. Created by Pensa Labs, the DIWire transforms drawn curves into bent wire that can be assembled to make just about anything.

“To date, desktop manufacturing has focused on 3D printers outputting plastic volumes and laser cutters cutting 2D planes. However, nothing exists that converts lines into bent rod, wire or tubular forms quickly, accurately, and repeatedly,” the Pensa Labs crew wrote in a recent Kickstarter post. “The DIWire can bend various metals and plastics, allowing for the output to be used as the final product. Additionally, the build volume is limited only by the length of the wire.”

Indeed, by being transportable, accessible and affordable, the DIWire fills the market gap between time-consuming hand-bending and large scale, mass production CNC wire bending, which is often too costly for custom, short-run productions.

This significantly changes the dynamics of STEM education, as well as local, mass customized, prototype and just-in-time manufacturing for industries ranging from aerospace, automotive, medical, to consumer products.

So what can DIWire be used to create? Specific examples listed on Kickstarter include antennas, robotics, architecture models, design prototypes, art, furniture, jewelry, small crafts, surgical implants, orthodonture, puppetry, lighting, stage sets and signage.

This sailboat autopilot has Atmel-Arduino under the hood

Recently, Bits & Pieces covered a story about a Maker by the name of Louis who designed an innovative kayak autopilot built around an Atmel-powered Arduino.

Today, we are going to be taking a closer look at an Arduino-based autopilot fitted into a large sailboat that is capable of keeping the vessel on a constant heading. According to the HackADay crew, Mike Holden uses a very cool digital compass equipped with LEDs to keep a steady course.

“Also included is an amazingly professional and very expensive 6 axis IMU. To actually steer the ship, Mike is using a linear actuator attached to the tiller powered by a huge 60 Amp motor controller,” explained HackADay’s Brian Benchoff.

“For control, [Mike] ended up using an [Atmel-powered] Arduino, 16-button keypad, and an LCD display. With this, he can put his autopilot into idle, calibration, and run modes, as well as changing the ship’s heading by 1, 10, and 100 degrees port or starboard. It’s able to keep a constant heading going downwind, and even has enough smarts to tack upwind.”

An Atmel-powered MakerBot in every school

The MakerBot crew has announced a new educational mission to put an Atmel-powered MakerBot Desktop 3D Printer in every American school.

According to Ben Millstein, the first MakerBot Academy initiative includes 3D printing bundles for classrooms, an awesome Thingiverse Challenge along with generous support from both individuals and organizations.

“[You can help] get the word out. Tell the teachers you know to register at DonorsChoose.org. Support a school [and] contribute to the effort by choosing a teacher; help get them set for the Next Industrial Revolution,” Millstein wrote in an official MakerBot blog post detailing the initiative. “[You can also] participate in the Thingiverse Challenge, develop models that teachers can use to improve science, technology, engineering and mathematics (STEM) education.”

Millstein also pointed out that the rapidly growing 3D market had caught the attention of US President Barack Obama who stated during a recent State of the Union Address that 3D printing “has the potential to revolutionize” the way we make almost everything – with America ready to host “the next industrial revolution in manufacturing.”

“We’re inspired by the President’s commitment to keep America at the forefront of the Next Industrial Revolution and we’re eager to do our part to educate the next generation of innovative makers who will keep our economy strong,” Millstein noted. “[We want to] get thousands of [Atmel-powered] MakerBot Replicator 2 Desktop 3D Printers into K-12 public school classrooms across the country — by December 31, 2013!”

Driving social change with Atmel and Arduino

Nominet Trust, one of the UK’s leading funders of social technology ventures, recently kicked off an initiative to find and recognize the most inspiring applications of digital technology for social good. Unsurprisingly, the Atmel-powered Arduino made the 100 item list, with Charles Leadbeater, a Nominet Trust board member and NT100 project lead, describing Arduino as “LEGO for electronics.”

“The core to an Arduino is a simple, ultra-low-cost circuit board, based on an open-source design, armed with an [Atmel] microprocessor which can be programmed with simple, open-source software tools by the user,” Leadbeater wrote in a recent Financial Times article. “The idea is that anyone should be able to turn an Arduino into a simple electronic device such as a light switch and sensor.”

As Leadbeater notes, Arduino was started by a group at the Interaction Design Institute at Ivrea in Italy as a way to get people making their own electronics hardware, just as simple software tools like Scratch, a project born at the MIT Media Lab and another entrant on the Nominet Trust 100 list, are helping children to learn to code.

“If the Arduino follows in Scratch’s tracks it will become ubiquitous: the Scratch website currently has more than two million registered users and four million shared projects,” said Leadbeater.

In addition to taking educational and Maker facilities by storm, Atmel-powered Arduino boards are now being deployed throughout the corporate world, with the hardware being used by designers, architects and engineers for prototyping purposes.

“It’s very easy to try out design by building a prototype so that they can see what solutions work and toss out those that don’t. This is much easier to do early in the design process before more money has been spent on bringing an idea to fruition; Arduino can play a key role here,” Brock Craft, author of “Arduino Projects for Dummies,” told ITPortalPro earlier this year. “Just a simple example – I know a lighting company that recently used Arduino to control dimmable lighting effects for architectural lighting products they were developing. Using an Arduino helped them try out their ideas in an afternoon, rather than waiting weeks.”

As we’ve previously discussed on Bits & Pieces, Atmel-powered Arduino boards illustrate the numerous advantages associated with an open source approach.

“From the out-of-the-box experience we want to know how long it takes to you to go from zero to something that works,” Arduino co-founder Massimo Banzi wrote in a recent Makezine article. “This is very important because it creates a positive reinforcement that you are on the right path. The longer that time is, the more people you lose in the process.”

According to Massimo, “we are all on the edge” of a new step in the Maker Movement.

“Some of you are surely working on the next big thing. Please keep at it, but keep in mind the overall experience,” he continued. “[Yes], you can put a processor that is 100 Mhz more than another one, but the way you interact with it makes a huge difference to people because it’s more important to take care of the experience people have when they learn than to give them power they don’t know what to do with.”

Massimo reiterated the notion of “people over Megahertz” earlier this week during the New York Hardware Innovation Workshop (HIW) in September, which kicked off right before the 2013 World Maker Faire in NYC.

“Every time you design a system to do everything, you end up with a system designed to do nothing. The challenge is to build a platform that solves a simple problem for a specific group of people: beginners for example,” Massimo emphasized during a panel discussion about the evolution of microcontrollers (MCUs). “Our boards are not the most powerful, but they enable people to get ideas into products very fast. It’s people over Megahertz.”

3D printing market worth $8.41 billion by 2020

Analysts at MarketsandMarkets have confirmed that the lucrative 3D printing market is projected to grow at a CAGR of 23% from 2013 to 2020, ultimately reaching $8.41 billion in 2020.
