This wireless iPhone charger is also a work of art

Developed as part of a diploma project by a University of Contemporary Design and Applied Arts (ECAL) student, Spira is a magnetic docking station that wirelessly restores power to an iPhone while turning the device into a decorative wall clock.

Described by its creator Alica Robbiani as an interactive picture, charger and clock, Spira was built around an [Atmel based] Arduino board and the principle of inductive charging. Utilizing a blend of wood, metal and plastic, the Maker sought to devise an ambient frame that would enable a magnetized iPhone case to hang decoratively on the wall thereby giving it a “place of honor in the home atmosphere.”

When attached in the upright position, the iPhone displays a set of animated white circles on the screen, each representing 10% of its battery level until fully charged. Users can also manually shift the position of the phone on the frame to display a wall clock. By rotating the phone, clock hands are revealed, projecting the current time.

“The telephone puts aside its usual functions and reinvents itself to become a key: its presence allows energy to spread to make the (heat-sensitive) painting react.”

Thermochromic paint is used as visual feedback, the Maker reveals. The color of the ink changes in correlation with varying temperatures, which enables the wall-mounted device to emit a new image inside the frame. Once the all-in-one structure is unplugged, the paint then returns to its starting color.

“The way of charging changes completely, and in spite of the power of gravity, we are challenged to let the telephone hung up, keeping us informed of the current time and state of the battery,” Robbiani writes. “The telephone puts aside its usual functions and reinvents itself to become a key: its presence allows energy to spread to make the (heat-sensitive) painting react. This is how a new image appears.”

In the meantime, you may also want to check out fellow ECAL design student Pauline Saglio’s recent creation: a unique series of three digital/analog hybrid clocks in an effort to meld the digital world with the analog act of winding a clock.

What is Ambient Security?

New technology and business buzzwords pop up constantly. Hardly a day goes by that you don’t see or hear words such as “cloud”, “IoT,” or “big data.” Let’s add one more to the list: “Ambient security.”

You’ll notice that big data, the cloud, and the IoT are all connected, literally and figuratively, and that is the point. Billions of things will communicate with each other without human intervention, mainly through the cloud, and will be used to collect phenomenal and unprecedented amounts of data that will ultimately change the universe.

As everything gets connected, each and every thing will also need to be secure. Without security, there is no way to trust that the things are who they say they are (i.e. authentic), and that the data has not been altered (i.e. data integrity). Due to the drive for bigger data, the cloud and smart communicating things are becoming ambient; and, because those things all require security, security itself is becoming ambient as well.  Fortunately, there is a method to easily spread strong security to all the nodes. (Hint: Atmel CryptoAuthentication.)

Big Data

At the moment, big data can be described as the use of inductive statistics and nonlinear system analysis on large amounts of low density (or quickly changing) data to determine correlations, regressions, and causal effects that were not previously possible. Increases in network size, bandwidth, and computing power are among the things enabling this data to get bigger — and this is happening at an exponential rate.

Big data became possible when the PC browser-based Internet first appeared, which paved the way for data being transferred around the globe. The sharp rise in data traffic was driven to a large extent by social media and companies’ desire to track purchasing and browsing habits to find ways to micro-target purchasers. This is the digitally-profiled world that Google, Amazon, Facebook, and other super-disruptors foisted upon us.  Like it or not, we are all being profiled, all the time, and are each complicit in that process. The march to bigger data continues despite the loss of privacy and is, in fact, driving a downfall in privacy. (Yet that’s a topic for another article.)

Biggering

The smart mobile revolution created the next stage of “biggering” (in the parlance of Dr. Seuss). Cell phones metamorphosed from a hybrid of old-fashioned wired telephones and walkie-talkies into full blown hand-held computers, thus releasing herds of new data into the wild. Big data hunters can thank Apple and the Android army for fueling that, with help from the artists formerly known as Nokia, Blackberry, and Motorola. Mobile data has been exploding due to its incredible convenience, utility, and of course, enjoyment factors. Now, the drive for bigger data is continuing beyond humans and into the autonomous realm with the advent of the Internet of Things (IoT).

Bigger Data, Little Things

IoT is clearly looking like the next big thing, which means the next big thing will be literally little things. Those things will be billions of communicating sensors spread across the world like smart dust — dust that talks to the “cloud.”

More Data

The availability of endless data and the capability to effectively process it is creating a snowball effect where big data companies want to collect more data about more things, ad infinitum. You can almost hear chanting in the background: “More data… more data… more data…”

More data means many more potential correlations, and thus more insight to help make profits and propel the missions of non-profit organizations, governments, and other institutions. Big data creates its own appetite, and the data to satisfy that growing appetite will derive from literally everywhere via sensors tied to the Internet. This has already started.

Sensors manufacture data. That is their sole purpose. But, they need a life support system including smarts (i.e. controllers) and communications (such as Wi-Fi, Bluetooth and others). There is one more critical part of that: Security.

No Trust? No IoT! 

There’s no way to create a useful communicating sensor network without node security. To put it a different way, the value of the IoT depends directly on whether those nodes can be trusted. No trust. No IoT.  Without security, the Internet of Things is just a toy.

What exactly is security? It can best be defined by using the three-pillar model, which (ironically) can be referred to as “C.I.A:” Confidentiality, Integrity and Authenticity.

CIA

Confidentiality is ensuring that no one can read the message except its intended receiver. This is typically accomplished through encryption and decryption, which hides the message from all parties but the sender and receiver.

Integrity, which is also known as data integrity, is assuring that the received message was not altered. This is done using cryptographic functions. For symmetric, this is typically done by hashing the data with a secret key and sending the resulting MAC with the data to the other side which does the same functions to create the MAC and compare. Sign-verify is the way that asymmetric mechanisms ensure integrity.

Authenticity refers to verification that the sender of a message is who they say they are — in other words, ensuring that the sender is real. Symmetric authentication mechanisms are usually done with a challenge (often a random number) that are sent to the other side, which is hashed with a secret key to create a MAC response, before getting sent back to run the same calculations. These are then compared to the response MACs from both sides.

(Sometimes people add non-repudiation to the list of pillars, which is preventing the sender from later denying that they sent the message in the first place.)

The pillars of security can be  implemented with devices such as Atmel CryptoAuthentication crypto engines with secure key storage. These tiny devices are designed to make it easy to add robust security to lots of little things – -and big things, too.

So, don’t ever lose sight of the fact that big data, little things and cloud-based IoT are not even possible without ambient security. Creating ambient security is what CryptoAuthentication is all about.

IR reflow oven for your prototype PCBs

When you use solder paste to assemble your prototype PCB (printed circuit board) you need a stencil or hypodermic needle to apply the paste to the pads on the board. Then you use an IR (infra-red) reflow oven to melt the solder. Scott Fritz, an Atmel IC designer on the third floor, found this neat home-made controller that turns a cheap toaster oven into an IR reflow oven. I assume the name Reflowster is a combination of the words “reflow” and “toaster.”

The Reflowster will do closed-loop control of a cheap toaster over so you can do IR reflow soldering on your prototype circuit boards.

The Reflowster is an Arduino-based controller that that gives you predicable and repeatable heating and cooling profiles to melt the solder paste and connect up all the components on your board. They got their start on Kickstarter, and have actually shipped, so all the Kickstarter people are rewarded. Now the Reflowster folks are starting to offer the product to the general public.

The Reflow controller V3 PRO from PCB POOL in Europe is another product meant to work with a toaster oven.

I have mentioned a similar reflow controller made by the fine people at PCB-POOL in Europe. That article also described how my buddy Wayne Yamaguchi was using a toaster oven a decade ago to make his PCBs. Wayne did not use a controller. He just did a whole bunch of tests until he was satisfied he was getting good whetting and solder fillets on his circuit boards.

The great thing about the Reflowster is that it is a closed-loop controller. It is actually measures the temperature of the oven, and then controls the power to it so that the heating and cooling match the profiles recommended by component makers like Atmel (pdf).

Precise temperature control is needed to do quality lead-free soldering.

While I love, admire, and respect my buddy Wayne Yamaguch’s “theory of experiments” approach, you might really need the Reflowster. If you want to use different ovens, or have changing wall voltage, or the boards you are soldering are different sizes or have a different set of components on them, you want a closed-loop controller. If the chips have a big pad on the bottom, the die-attach-paddle, you need reflow. The other big factor is lead-free solder. Many of the crazy analog engineers I hang out with still use tin-lead solder for prototypes. It looks better, it feels better, and lead solder is more reliable. We also pull the solder off the reel by biting it gently and tugging, so we don’t have to set the soldering iron down. Lead poisoning might explain why we are all crazy. But if you are sane and insist on using lead-free solder, the preciseness of reflow control is important.

Solder paste application is like silkscreening T-shirts. Instead of silk the stencil is stainless steel. Instead of ink you use solder paste. Instead of T-shirts you do printed circuit boards.

Solder paste has its own hassles. You should refrigerate open containers so the little solder balls do not oxidize and change the reflow parameters. I am not sure the same caveat applies to when you use a big hypodermic to apply the solder paste. There the hassle is you have to do it one pad a time. A solder stencil is a thin stainless steel sheet where the PCB fab house has etched through all the areas where there is supposed to be solder. Sometimes called the “cream layer” Its not exactly the solder mask art, but it is pretty close, depending on your particular design. I know you can set up OrCAD 9.2 to do it, and I am sure other CAD packages can make it, or the PCB fab house can create one from your solder mask layer art.

Here is a typical solder stencil from Stencils Unlimited. With one swipe of a squeegee you apply solder paste to the pads for your chips and passive components.

The fine folks at Sunstone used to offer a free stencil, now it looks like they charge a little. Most fab houses can supply one. Assembly houses like Screaming Circuits or Advanced Assembly have the relationships with board houses to they can make your stencil when they assemble your boards. If you are really masochistic, and have a high-powered CO2 laser cutter handy, you can make your own stencils. You can also live in a cave and use flint tools, but I prefer to operate a little higher on the food chain. The LPKF laser mill can make your stencils as well.

This solder stencil from Proto-Advantage lets you apply solder paste for a QFN-32 chip.

There are also hybrid approaches. You can buy cheap solder stencils just for high-pin-count chips on your board. You squeegee the solder paste onto the board for each of those parts, Then you can use a hypodermic for the passive components or hand-solder them after you reflow the big chips.

If you are a big-time engineer on a big-budget project then just contact Screaming Circuits or Advanced Assembly or you local board assembly house (not PCB fab, but board assembly). I know Screaming Circuits can do it all since they have teamed up with Sunstone and Digi-Key. Just send Screaming Circuits the fab Gerber and fab files which they send to Sunstone, the assembly drawing and insert file which they use themselves, and the BOM (bill of material) they order the parts with from Digi-Key. They can do quick-turn and they can ship anywhere in the world.

So the prototyping ecosystem is like this:

• If you are a hobbyist use DIP (dual-inline plastic) chips with 0.1 inch lead spacing and through-hole passive components. You might use surface mount chips on DIP breakout boards.
• If you are a pro-hobbyist or low-budget engineer buy a temperature-controlled Weller soldering iron or a Metcal and a good stereo microscope. Now you can hand-solder surface mount boards. For chips with bottom pads you have to either heat the whole chip with a big soldering iron, use a heat gun, or try to wick the solder in from vias you design in on the backside of the board.
• If you are a hobbyist doing low-volume manufacturing or a medium-budget engineer, go to solder stencils and reflow ovens.
• If you are a hobbyist that hit it big or a big-budget engineer, use the board house to order the parts, get the PCB fab, and assemble and maybe even test your board.

TQM Solutions knows that total quality management means you not only have a mountain of documentation, but that you organize that mountain.

Note that last item. See, as an engineer, your real job is to make a set of documentation so the design can get manufactured by non-engineers and non-technicians and non-hobbyists. Its nice you are a hands-on person. Heck, its critical you are a hands-on person to be a good engineer. But your real responsibility is making sure the CAD files are correct. it might speed things up if you make a first-spin board yourself, and its neat if you make the board on an LPKF mill and you can get parts from the factory floor or Radio Shack or a salvage yard.

I used to design products with parts I found cheap at places like Weird Stuff Warehouse in Silicon Valley. Then one of my designs went to production but Weird Stuff had sold off all the parts I had used. Now I select parts from distributors.

The great thing about using Screaming Circuits and Sunstone and a distributor like Mouser or Arrow or Newark or DigiKey is that you are proving out your documentation. You make it clear to Screaming Circuits that if your pick-and-place insert file has mistakes they tell you, you fix them and they use that file. This way, when they see that the part origin for a DPAK is at the pad and not the part center, they know the vacuum picker cannot pick it up, so you catch that AND FIX IT. If your Gerbers have problems you make sure Sunstone tells you, or you use the free DFM (Design for manufacturing) check offered by Advanced Circuits. Then you FIX THE FILES. Same deal for any BOM mistakes. Make sure somebody tells you so you can FIX THE FILE, and not the text file, you fix the CAD file in OrCAD or Altium or whatever, so it spits out a perfect BOM.

Now when you send the CAD files to China to get assembled on the cheap, you know the files are correct. Anything less and you are not an engineer, you are an amateur. Proto Express even works with a Chinese partner to ensure you can get cheap-high volume boards that work as well at the Proto-Express boards made right here in Silicon Valley.

The oqo Model 2 used a Via processor. The third model with an Intel Atom never got built since they ran out of money (courtesy Engadget).

This level of diligence and exactness is critical. I worked at oqo, a San Francisco start-up that made the first palm-top computer that ran real Windows OS. The first model was based on the Transmeta “emulated” x86 processor. The second model used a Via chip. Lesson there is never base a business plan on being smarter than Intel. The third prototype never went into production. I had left the company for National Semiconductor, but pals there told me they used an Intel Atom processor and it was a real product that could really work good. But they were running out of money. So I assume in a big rush, they sent the design to the Chinese contract manufacturer. A pal familiar with the company told me oqo had to fly out an engineer to China and there were 1000 ECOs (engineering change orders) to get the design ready for high-volume manufacturing. One thousand mistakes. Now it probably didn’t matter, but its nice to think that if they had scrubbed the CAD files, the fab, the assembly, and the rework documentation through a US quick-turn prototype manufacturer, and fixed most of those mistakes, then maybe they could have gotten that product to market and saved the company.

This is a perfect example of the asymmetric respect problem in engineering. The Chinese manufacturing engineers respected those high-tone former Apple designers at oqo. But the oqo engineers may have thought manufacturing was some triviality and beneath them. Perhaps they thought any idiot should be able to do it. Sorry. Wrong. Dead wrong. Dead just like oqo is today. You need to be every bit as smart, clever, and creative to do manufacturing and test as to do design work. When you take a product all the way to production, you will learn to respect everybody involved. Respect the planners, the clerks, the assemblers, and ALL the engineers. So be a good and respectful design engineer and make sure your CAD files are a good as they can be before you send them out for production. That is your responsibility, not a Flextronics responsibility.

The cover of my mentor Bob Pease’s book Troubleshooting Analog Circuits has one of his “airball” prototypes on the cover. Application engineers like Bob can do proof-of-concept, but don’t try sending this out for high-volume manufacturing.

So like all things, prototyping has an analog continuum to it, There is a place for quick-and dirty hacks. There is place for super-diligence. And there is a whole spectrum of tradeoffs for an appropriate design effort in between those poles. Just don’t do some rush-job today that you just know will bite you a few months later.

[Update] I showed this post to Wayne Yamaguchi and he had this great comment:

“One of the major drawbacks to solder paste is the shelf life.  No matter how you buy it, the container and contents will go bad in about 6 months time, even in the refrigerator.  It’s the flux that ages and slowly solidifies making the reflow consistency different over time.  It’s just a real pain to dispense the paste with a tiny-tip syringe when it it’s fresh, and even worse when it has aged a bit. If I recall correctly, the smallest syringe runs about $50.00.  You can solder a lot with that but if you only make one proto this is an expensive proposition.

“Mine tends to absorb water over time and this makes it pop when reflowing, blowing off chunks of solderpaste in all directions. I can hand-solder 0402 and DFN parts with the soldering iron.  I only need the hot-air station for pads that are not exposed, like power pads and some SMT inductors. I would recommend a really good soldering iron or two, and a general-purpose hot air station if you want to hand-solder small runs of boards. You will need one with a 0.2mm tip or smaller for the leadless and 0402 parts.

“I prefer to still use leaded solder.  It solders at a lower temp and the chemicals are less caustic, unlike the solder flux used for leadless solder.  Unless I have to, I try to use “no clean” flux and occasionally will use Kester 331 (IIRC) for gold-plated pads.

“Good stencils are cut non-vertical.  The edges are beveled so the bottomside is slightly larger than the top, making the solderpaste less resistant to sticking to the stencil.  Hopefully, when you lift the stencil the solderpaste adheres to the PCB and not the stencil.  I’ve never actually seen the process, but, I always imagined  that the paste would not all tranfer.  I guess it works.  Just doesn’t work in my mind.  The bevel is only 5-10 degrees.  Hardly noticeable by the eye, but, I guess it makes a difference.

“Another gotcha will come when you doing rework.  You remove the part in question and/or use solderwick to clean the pads.  If you try and apply solderpaste right away the residual heat will outflow the flux from the syringe tip which is most frustrating as now the tip is full of paste with no flux.  When this occurs it is like concrete and won’t flow.  It is possible to drain more than the tip into the larger part of the syringe tube rendering the whole syringe load bad.  You can unscrew the tip and plunge out the bad material, but, who knows if you now have the right ratio of flux to solder anymore?  If this is the tube from the vendor you can kiss $50.00 down the drain.  If you transferred solderpaste to a smaller syringe the loss is less than $50.00.”

I guess all those years at HP and Agilent, and then being in business for himself gave Wayne a valuable perspective on prototyping. Many thanks to him, and add you own comments below.

Rewind: The most futuristic lamps of 2014

From streaming music to recreating the weather, lamps are getting smarter. And well, 2014 was full of some bright ideas — literally! Here are some of the ones that caught our eye over the last 12 months.

Cloud

Developed by Richard Clarkson, Cloud is an interactive lamp system comprised of an [Atmel based] Arduino, some fluffy cotton and a cloth cord. According to the designer, the installation serves as a semi-immersive lightning experience and a speaker with visual feedback to mimic a thunderstorm in both appearance and entertainment.

Patch of Sky Arduino Lamp

Patch of Sky is a set of three Internet-connected ambient lights, enabling users to share the sky above them in real-time with friends and loved ones across the world. Any of 11 potential weather scenarios – including snow, fog, sun, drizzle and heat – animate the mirror with a gently pulsing gradient color. Driven by an Arduino unit, the semi-circular object gathers weather information based on one’s current Facebook location and displays it with light animations. Meanwhile BERGCloud connects the interactive “lamp” to the web.

Tempescope

Sure, you could just download a weather app or turn on the news to check the latest conditions, but what fun is that? A Maker by the name of Ken Kawamoto recently developed an ambient physical display that can visualize the day’s forecast, right from the comfort of your living room. While most home weather displays boast an LED screen or other methods of revealing what’s going on outside your front door, the Tempescope literally emulates the impending weather from your bookshelf, coffee table or desk. Aside from the [Atmel based] Arduino, the active weather lamp-like device is controlled by a water pump, ultrasound mist diffuser, a series of LED lights, and other assorted components connected to a PC — all concealed within a clear acrylic box.

LUZ

Developed by Marina Mellado, LUZ is a self-devised lamp for those who are either physically or psychologically affected by the lack of daylight — typically experienced in the upmost northern hemisphere during winter. Comprised of two LED stripes (RGB SMD5050), an Adafrut color sensor (TCS34725) and an Arduino Uno (ATmega328), the electronic system was programmed to modify the lamp’s light colors based on the weather conditions outside of the nearby window.

Waves

Having spent countless hours sitting as his desk, Frank Cohen had always found lava lamps to provide a calming effect that would help him wind down after a long day’s work. This was the inspiration behind his decision to devise a modern-day version of the once-popular decorative novelty item, which he took to Kickstarter. Cohen went ahead and created a smart Bluetooth speaker equipped with rows of programmable LED lights, each of which illuminate customizable diffusion filters. Whether one wants to keep it on their desk as a conversation piece or furnish the shelves on their walls, the possibilities are endless with this lava lamp.

Walkalight Drone

The Walkalight Drone is described by its creators as a lighting exploration that merges quadcopter and smart sensor technology to create the ultimate in personal illumination. The air-filled, balloon-shaped orb floats above a user like a street lamp, using motion sensors to follow their movements.

CROMATICA

Interacting with objects in a new way has always been the main focus of Milan-based design studio Digital Habits. Simply stated, CROMATICA is a half speaker and half desk lamp capable of creating an ambient experience through the fusion of light and sound. 

This digital hybrid is controlled by a gestural interface as well as remotely via its companion Android and iOS app. Designed to deliver both light and sound functions, the open-source, Atmel powered CROMATICA features wireless 4.0 Bluetooth connection for streaming music and a RGB lamp for multiple ambient effects.

Junior

Dutch design student Trieuvy Luu has created a “living lamp” known as Junior — a whimsical lamp that depends on a user’s breath to keep his energy up. By breathing toward the lamp, Junior illuminates — literally and figuratively — into the perfect playful mid-day distraction. The lamp is powered an Arduino Mega (ATmega1280) paired with OpenCV facetracking. Additional project components include three servos, a camera, a microphone, a temperature sensor and six LED strips.

Harpa Night Light

Originally created by Trent Brooks for his daughter, Harpa is a large handcrafted elephant lamp shade with Wi-Fi controlled RGB LEDs, a microphone, a speaker and a custom iPad application to teach children about color. The electronics are driven by an Arduino Mega 2560 (ATmega2560) with an Ethernet shield for network control. Connected to the board is a 50cm 5V RGB addressable LED strip with 30 LEDs, a 3.3V microphone module for sound detection and an 8ohm speaker for playing back generated ‘white-noise’ audio.

Death Star Lamp

Always wished to have your own Star Wars Death Star? If so, you’re in luck. Nurun founder David Bliss has modded an IKEA PS 2014 lamp using an Arduino Uno (ATmega328), an Arduino Motor Shield, a linear stepper motor, NeoPixel LEDs, as well as the SmartThings platform to control the lights.

Luma

Following a Kickstarter campaign earlier this year, Luma is described as “a smart lamp for the 21st century.” An ideal accessory for any office, bedroom or nursery, the smart lamp is equipped with a USB charger, a built-in speaker and a microphone. This allows users to do everything from charge their mobile devices and listen to their favorite tunes to make calls and set the mood — all with the press of a smartphone button.

Pinokio

As kids filled with thoughts from Disney movies, we all imagined that our household items might one day magically come alive and interact with us. Makers Shanshan Zhou, Adam Ben-Dor, and Joss Doggett have now made that dream a reality with their face-tracking lamp, aptly dubbed Pinokio. According to its creators, the gizmo is an exploration into the expressive and behavioral potentials of robotic computing. The lamp’s lifelike personality is made possible through its on-board [Atmel based] Arduino which is programmed to procedurally manipulate six servo motors. The lamp can even be toggled into “introvert” or “extrovert” modes, which will drastically alter the movement decision-making process.

Philips 3D-Printed Lamp

It’s without question that the industry experienced quite a surge of 3D printers and smart home technology over the last 12 months. That’s why it’s no surprise that our friends at Philips, in collaboration with design studios WertelOberfell and Strand+Hvass, developed an unprecedented 3D-printed lamp. Fully-compatible with the company’s Hue wireless lighting system (which features Atmel’s ZigBee and Lightweight Mesh Stack), users can set the mood via its dedicated mobile app.

Notti Smart Lamp

Fresh off an extremely successful Kickstarter campaign, Notti is a smart lamp that ca be programmed to emit various colors when receiving a text or Facebook update, carrying out an IFTTT task, being awoken by your morning alarm, or even blasting tunes. Devised by Hong Kong-based startup Witti Design, the unique light embodies an abstract geometric shape — which kind of looks a piece of The Crag from Nickelodeon Guts. Notti remains white until activated on, where a user can then select from as many as 16 million colors. Equipped with a 3W LED light, Notti connects to your mobile device via Bluetooth.

---

As we look ahead to 2015, smart lighting is prepared to surge ahead. According to a recent report, the market for MCU-powered LED lighting is projected to reach $525 million by the year 2019, while the customizable ‘mood’ lighting and wireless sensors space is expected to hit $220 million. With CES just around the corner, we can’t wait to see what new innovations will be ‘brought to light!’

Zymbit wants to get your IoT ideas to market in days, not months

As the next frontier of the Internet, the IoT represents a compelling opportunity across a staggering array of applications. That’s why the team behind Zymbit has developed a platform of open hardware and software devices to enable Makers, engineers and developers alike transform their IoT ideas into real-world products in a matter of days, not months. In an effort to deliver secure, open and interactive devices for our constantly-connected era, Zymbit is hoping that its pair of solutions — the Y and Z Series — will help accelerate adoption.

The company, who will be exhibiting inside our CES booth next month, has recently unveiled two devices each designed to interface with our physical world in a more secure, authenticated manner. Zymbit seeks to provide users with local and remote live data interaction, along with a low-power MCU, battery-backed operation.

“Y-series motherboards incorporate some of the latest secure silicon from Atmel, providing accelerated processing of standard open security algorithms. A separate supervisor MPU takes care of security, while you take care of your application,” a company rep writes.

Based on the Atmel | SMART SAM D21, the Y Series motherboard is electrically robust with enhanced security provided via the ATECC108 crypto engine and ATWINC1500 Wi-Fi controller. Ideal for those developing next-gen IoT applications, the board is easily customizable and compatible with Atmel Xplained Pro wingboards, Arduino shields, Raspberry Pi B+, as well as ZigBee, cellular and POE module options.

Meanwhile, the Z-series not only boasts several standard expansion and mounting options, but allows 3D-printable parts to easily be integrated for ultimate personalization.

Each Zymbit device features a dedicated hardware crypto engine to ensure that only trusted data is exchanged between devices. Security processes run within a supervisory ATSAMD21J18A, separately from its ARM Cortex-M0+ application MCU.

The unique Zymbit architecture delivers three key security components:

• Authenticated data source with 72-bit ID Serial Number
• Secure data transmission with SHA 256
• Private data transmission with Wi-Fi embedded AES engine

The Z-series packs several addition security features, including private data transmission with AES engine 124/192/256, secure data transmission with SHA 1/2/3, public key acceleration, black key management and high assurance boot.

Wait… there’s more! In the forthcoming weeks, the team plans on revealing an innovative (and extremely cool) way for devices, users and data to interact through visually, audibly and of course, by touch. See it for yourself next month at CES!

Report: 18% of organizations own 10 or more 3D printers

60% of organizations claim high start-up costs are a main factor in the delay of implementing 3D printing strategies, a new survey from Gartner has revealed. However, the study also found that early adopters of the technology are finding clear benefits in multiple areas.

Earlier this year, Gartner conducted a worldwide survey to determine how organizations are using or at least planning to use 3D printing devices — many of which are based on AVR XMEGA, megaAVR and Atmel | SMART ATSAM3X8E microcontrollers, including the incredibly-popular MakerBot and RepRap.

“3D printing has broad appeal to a wide range of businesses and early adopter consumers, and while the technology is already in use across a wide range of manufacturing verticals from medical to aerospace, costs remain the primary concern for buyers,” explained Pete Basiliere, Gartner Research Director. “3D printer vendors must work closely with their clients to identify potential applications of the technology that may have been overlooked, and improve the cost-benefit ratios of their products. Organizations that wish to experiment with the technology without incurring start-up costs should consider partnering with a local 3D printing service bureau.”

Some key takeaways included:

• While prototyping, product innovation and development are the main uses, 3D printing is also being implemented extensively in manufacturing applications.
• By 2018, nearly half of consumer, heavy industry and life sciences manufacturers will use 3D printing to produce parts for the items they consume, sell or service.
•  53% of respondents indicated that managers of R&D engineering or manufacturing are the primary influencer driving any 3D printing strategy.
• A vast majority of those surveyed felt “overwhelmingly” that using a 3D printer as part of their supply chain generally reduces the cost of existing processes, especially research and product development costs.
• The mean cost reduction for finished goods is between 4.1% and 4.3%.
• 37% of respondents ranked the quality of the finished piece as the primary factor in selecting a 3D printer, while 28% cite price is the most important
• 9% of respondents felt that production speed, the range of materials the printer could use, or size of parts it could create were the most important things to consider when deciding on a printer.
• 37% of organizations had just one 3D printer within their company, while 18% own 10 or more.
• The average number of printers per organization was 5.4.

“Clearly there is much room for future growth in this market, but vendors need to work on tools and marketing that show how the technology can be applied and drive competitive advantage. 3D printing vendors that take the time to articulate the value of their product in terms that align with their clients’ needs will be well-positioned to capitalize on any future growth,” Basiliere concludes.

Rewind: 25 wow-worthy wearables from 2014

As we turn the page on 2014, we’re taking a quick look back at some of our favorite wearables from the last 12 months. While analysts predict the market to experience an uptick heading into 2015, we can only wait and see what new products emerge!

Moto 360

In what may have been the most highly-anticipated Android Wear smartwatch to date, the Moto 360 is equipped with a bold round face, a MXT112S powered capacitive touch display, a heart rate monitor, an ambient light sensor, and is now being sold in both metal and leather models.

---

TomTom Runner

The popular GPS sports watch is equipped with a built-in heart rate monitor, a large monochrome LCD display and one-button control. In addition, the Atmel | SMART ATSAM4S8C based TomTom Runner is embedded with an accelerometer and sensors allowing it to work both outdoors, indoors and even on a treadmill, thus providing providing a user with the kind of data they’d expect to find on most sports watches — such as distance, pace, stride length, calories burned and lap times all in real-time.

---

Narrative Clip

The future, for anyone who wants to tell their own story, has never looked brighter. That is because of the Atmel | SMART SAM9G25 powered Narrative Clip — a tiny, automatic 5-megapixel camera paired with an app that offers users access to a “photographic memory” which is both searchable and shareable. Clip it onto your shirt and let it snap away, recording all your daily activities in 30-second increments. Kind of like a GoPro but less obtrusive, always on, and of course, interconnected.

---

GLOW MOTION

GLOW MOTION has its sights set on revolutionizing the concert experience with their latest LED wristbands. Capable of being programmed with a range of light patterns emitting any of 16 million colors, the wearable device is enabling fans to become integrally involved in events. The devices not only receive signals from a centralized control module, but making this idea even ‘brighter’ is the fact that the wristbands can communicate with one another during a show.

---

DrumPants

Ever catch yourself drumming on your thighs? Your table? Your desk? Your steering wheel? Now, starting a one-man band is as simple as wearing this musical kit. DrumPants, dubbed by its creators as “the world’s industrial quality wearable musical instrument,” transforms your outfit into a full ensemble with 100+ built-in high-quality sounds. Its control box — which is powered by an Atmel | SMART ARM Cortex-M3-based MCU — features an ultra-low latency Bluetooth 4.0 chip, a built-in sound engine for 1/8-inch headphone jack, 128 instrument sample banks and a Micro-USB for connection to a laptop or PC.

Smart Hoodie

In an attempt to demonstrate that wearables don’t necessarily need to be confined to the wrist or face, two students at New York University’s Interactive Telecommunications Program (ITP) explored innovative ways fabric could be used with electronics. Using an [Atmel based] Arduino and an Arduino GSM shield, the pair designed what they call the “Smart Hoodie,” a hooded sweatshirt that can respond to various gestures — touching the hood, touching a sleeve and rolling up a sleeve, each of which send a different text message to a pre-programmed contact.

---

TZOA

While a majority of the wearable space has been focused on tracking what’s inside our bodies such as activity and stress levels, a new kind of device is emerging, one in which monitors what’s going on outside of us — specifically in our environment. Unlike others on the market today, similar to the recently-unveiled AirBeam handset, TZOA is a gadget that measures air pollution and UV exposure in one’s immediate environment using advanced sensor technology.

BB.Suit

Dutch designer Borre Akkersdijk recently launched a unique form of 3D-printed garments earlier this year: a onesie capable of turning its wearer into a mobile Wi-Fi hotspot. The first version of the suit — which made its debut back at SXSW — featured electrical threads woven into its fabric along with GPS and a musical library. A wearer’s location was displayed on Google Maps using the suit’s built-in GPS. Meanwhile, as a demo for the show’s music festival, the Maker collaborated with the online platform 22tracks to enable a wearer to upload songs. When musicians around the event located the BB.Suit, they had the ability to upload the tunes directly onto the suit. Talk about a ‘walkman!’

Sensory Fiction

They say stories can come to life, and well, one group of MIT students have taken that idiom to an entirely new level. The team of Makers has recently created a wearable book that uses networked sensors and actuators to create a sort of cyberpunk-like Neverending Story, blurring the line between the bodies of a reader and protagonist. The current prototype is comprised of a vest that plugs into a computerized copy of Tiptree’s novella. The vest — controlled by an [Atmel based] Arduino board — swells, contracts, vibrates, heats up or cools down as the pages of the book are turned. 150 programmable LEDs are used to create ambient light based on changing setting and mood, the book/wearable support a number of outputs, including sound, a personal heating device to change skin temperature, vibration to influence heart rate, and a compression system to convey tightness or loosening through pressurized airbags.

Self-Lacing Shoes

Aside from a time-travelling DeLorean DMC-12 and hoverboard, there is one other notable futuristic design from Back To The Future II that has left the world eagerly awaiting its inception: self-tying laces. While Nike has recently announced that it will be debuting these automated kicks in 2015, one Maker decided to take it upon himself to equip a pair of Air Mag sneakers with an Arduino Pro Mini (ATmega168) along with several other electronic components.

---

Hashtag Gloves

If you’re like our team, then you are huge fans of late-night television. From the days of Johnny Carson to Jay Leno to Jimmy Fallon, we love it all — which is why this recent project from a group of Olin College students certainly caught our attention. Inspired by The Tonight Show skit featuring Justin Timberlake, the Makers devised a new invention: Hashtag Gloves. Rather than having to pull out their smartphone and access its mobile app, Twitter users can simply tap their fingers twice using the “hashtag” symbol and speak loudly.

---

Sonar-Asssisted Device

Led by Wake Forest University professors William Conner and Paul Pauca, a group of students created an Arduino LilyPad (ATmega168V) powered wrist-worn device, aptly named HELP (the Human Echo Location Partner), that would help those who are blind get around, serving as a supplement to commonplace aids like canes or guide dogs. Based on the e-textile Arduino platform, the wearable device runs JAVA-like code, and features sonar distance sensors responsible for measuring the distance of objects and relaying this data to two smartphone vibrating motors. The frequency of vibrations is proportional to the distance from the detected object. In other words, the closer the detected object, the faster the motors vibrate.

---

x.pose

Designers Xuedi Chen and Pedro G. C. Oliveira recently debuted x.pose, a wearable data-driven sculpture that changes opacity to expose a person’s skin as a real-time reflection of outgoing data. Using an [Atmel based] Arduino and Bluetooth, the app communicates with a layer of reactive displays that reflect the volume of information generated by the wearer.

---

ChronodeVFD

John De Cristofaro grabbed the attention of countless Makers when we shared his Steampunk-inspired wristwatch powered by an ATMega88 microcontroller (MCU) earlier this year. At the core of the wearable device lies an ATMega88 MCU, while the real-time clock is a Maxim DS3231. The VFD display is driven by a Maxim MAX6920 — a 12-bit shift register with high-voltage (up to 76V) outputs. In addition, the circuit itself is powered from three voltage rails, and there a few onboard sensors — one analog and two digital.

---

Nixie

If your selfies weren’t awesome enough, you’re in luck. A team of Makers have set out to take photography to whole new heights… literally. Sure, smart watches bring smartphone features to wearers’ wrists, but can it fly freely and take video as it soars through the air? Stanford University researcher Christoph Kohstall, along with a team of engineers and designers, has formed a dream team to develop the Nixie. This wrist-mounded quadcopter hybrid just may hold the future of wearables, all while weighing less than a pound.

---

Tattoo Music Machine

Moscow-based artist Dmitry Morozov — commonly referred to as ::vtol:: — has created a unique sound controller to read musical scores implanted in tattoos. The scanning instrument is comprised of a metal railing, hand controllers and parallel black line sensors that move along the arm using a stepper motor. In addition, it is equipped with a Nintendo Wii remote control and an Open Sound Control to enhance the sound possibilities. A stepper motor guides the device along the inked lines, while the length of each bar coincides with the duration of an emitted sound. On the hardware side, key features of the musical creation include an Arduino Nano (ATmega328), a Nord Modular G2, a Symbolic Sound Kyma X, and a six-channel PVC pipe sound system.

---

Knitgadget

Royal College of Art student Yen Chen Chang recently debuted the Knitgadget, a glove that allows users to control various devices, musical or otherwise. The wearable device is comprised of conductive yarn that’s 80% polyester and 20% stainless steel (and 100% pure awesomeness). Chang knit and crocheted a series of objects that control devices by rubbing, pulling and stroking. When manipulated, the overlap of the metal fiber causes the textile to change conductivity which is then measured by an [Atmel powered] Arduino and communicated to the gadgets.

---

Vega Edge

Made of laser-cut leather, the Edge is a wearable light that snaps securely onto your clothing with the help of four strong neodymium magnets. You can wear it discreetly by day or brightly at night with your winter coat, cardigan, hood, scarf, handbag, collar, pocket, belt, or wherever you’d like a touch of light. According to project designer Angella Mackey, the Edge can also be worn for added visibility at night while cycling, jogging or walking. Indeed, traditional bike lights are often forgotten on the bike frame, leaving them vulnerable to theft. The Edge will stay with you, so you’re always prepared and visible.

 Perhaps most importantly, says Mackey, the Edge is designed to look good even when the lights are off.

Robotic Dress

A collaboration between 360 Fashion Network CEO Anina Net, Polish couture designer Michal Starost and IT architect Bruce Bateman has led to world’s first robotic dress powered by Atmel MCUs. The dress made its catwalk debut at the “When Technology Meets Fashion” event held during Beijing Design Week. In addition, the robotic garment features 6 servo-controlled support arms comprised of fiberglass reinforced with aluminum, custom software and a high-powered battery pack. In what sounds like something out of Hunger Games, the arms lift in sync to convert the dress from a day dress to an evening gown.

---

Personal Space Dress

Maker Kathleen McDermott recently debuted the “Personal Space Dress,” an article of clothing that literally expands a wearer’s personal buffer zone. The dress is the second in a series of projects dubbed Urban Armor, which consists of playful, Arduino-powered pieces that help women assert control over their personal and public space. In the case of the Personal Space Dress, a pair of proximity sensors and a plastic armature allow the garment’s hemline to expand outward when a fellow individual comes too close to the wearer.

---

Smart Eyelashes

Building upon her existing ‘Beauty Technology’ prototypes, Katia Vega developed a new smart eyelash system, which transformed basic eye and facial movements into programmable actions. Think Google Glass, just without the Glass. The lashes are chemically metallized to mimic a natural, black color, and are capable of amplifying emotions that the wearer wants to communicate by presenting noticeable, exaggerated visual compositions. Impressively, Vega was able to levitate a small drone simply by blinking at it.

---

3DTouch

A pair of students at the University of Wyoming have developed 3DTouch, an intelligent device that enables wearers to interact three-dimensionally with their computers. Dating back to the 1960s, Doug Engelbert’s mouse has dominated the way in which humans have communicated with their PCs. Though 3DTouch has an optical flow sensor that measures movement against a two-dimensional surface similar to its ancestral device, the smart thimble will now let a wearer control an onscreen mouse with a wave, tap or poke of a finger. Even cooler? Having more than one 3DTouch on different fingers facilitates multi-touch interaction. Connected to an Arduino Uno (ATmega328) controller, the input device is equipped with a 3D accelerometer, magnetometer and gyroscope. This allows the data from each sensor to be compared and combined to produce a far more precise estimate of orientation than a single measurement alone.

Mel Li’s Exoskeleton

Cyberpunk films and novels are often set in post-industrial dystopias characterized by extraordinary cultural ferment and the use of technology in ways never anticipated by its original creators. As William Gibson noted in Burning Chrome, “The street finds its own uses for things.” Although Gibson wrote those words way back in 1981, they more than aptly describe the cyberpunk build designed by Maker Mel Li, Ph.D that was showcased at this year’s Maker Faire Bay Area. The rather impressive costume includes color changing LEDs on the spine and front that are controlled by Arduino boards with both AVR and Atmel | SMART MCUs and on-board RGB controllers (respectively) – powered by 16 AA batteries, 1 LiPo rechargeable battery, two 2032 coin cells and one 9-volt battery.

---

Embedded Ballet Shoes

Designed by Lesia Trubat, Electronic Traces (E-Traces for short) are a pair of embedded pointé shoes which allow ballerinas to recreate their movements into visual sensations using an accompanying mobile app. Equipped with LilyPad Arduino boards (ATmega168V), E-Trace records the pressure and motion of a ballet dancer’s feet and transmits the signals to an electronic device. The application enables the wearer to trace the data graphically, viewing the movements made in video form, extracting images and even printing them for later use. This can certainly come in handy for those ballerinas seeking to improve their choreography and hone their skills.

---

Skin Buttons

Developed by Carnegie Mellon University’s Future Interfaces Group, Skin Buttons are touch-sensitive projected icons made on a user’s skin. The prototype smartwatch contains four fixed-icon laser projectors along with accompanying infrared proximity sensors. These are connected to an ATmega328P based Femtoduino board, which communicates over USB with a host computer. Additionally, a 1.5-inch TFT LCD display is driven from a host computer. While the team used an external computer for prototyping, it appears that a commercial model would be self-contained.

What a year it’s been! As we reflect back on 2014, we can’t help but eagerly await CES 2015 — and the latest wearable tech that’ll surely ensue!

Report: 30% of smart wearables will be inconspicuous by 2017

As previously reported on Bits & Pieces, we can expect to see wearable technology become less invasive over the next couple of years. Aside from an emergence in smart clothing and e-textiles, a new study from Gartner has revealed that the wearables market will continue to expand and evolve with 30% of the devices to become completely unobtrusive to the eye by 2017.

“Already, there are some interesting developments at the prototype stage that could pave the way for consumer wearables to blend seamlessly into their surroundings,” explained Annette Zimmermann, Gartner Research Director. “Smart contact lenses are one type in development. Another interesting wearable that is emerging is smart jewelry. There are around a dozen crowdfunded projects competing right now in this area, with sensors built into jewelry for communication alerts and emergency alarms. Obtrusive wearables already on the market, like smart glasses, are likely to develop new designs that disguise their technological components completely.”

Gartner went on to share several other predictions around the consumer devices market, including:

• By 2018, more than 25 million head-mounted displays (HMDs) will have been sold as immersive devices and virtual worlds will have transitioned from the fringe to the mainstream.
• Interest in HMD devices — which power virtual reality (VR), augmented reality (AR) and other smart glass apps — will continue to rise. So much so that, by 2018, the technology behind them will be found throughout both consumer and business scenarios.
• More stylish, consumer-grade video eyeglasses will result in explosive growth for HMDs — driving device adoption when paired with VR and AR content.
• By 2016, biometric sensors will be featured in 40% of smartphones shipped to end users.
• Fingerprint scanning will be the primary biometric feature introduced by most vendors, given its intuitive and unobtrusive usage.
• Other biometrics, ranging from facial and iris to voice and palm vein authentication, will also surface yet will remain relatively niche.
• Through 2017, one-third of consumers in emerging markets will have never owned a Windows device.
• In mature markets, PC penetration is still relatively high with more than 90% of consumers currently using a Windows PC.
• The rise in smartphones and their subsequent drop in price will lead some users to purchase their first smartphone for under $50.

Report: 2015 is expected to be a breakout year for wearables

We’re just weeks away from a breakout year for wearables, new research from Forrester has revealed.

“In 2015, wearables will hit mass market,” Forrester’s JP Gownder writes in the company’s most recent blog post. “With Apple’s much-anticipated Apple Watch slated for release early next year, the already hype-heavy conversation will reach new heights.”

The research firm joins other tech industry analysts in proclaiming 2015 as the pivotal year for wearable technology. If you recall, back in October, Gartner named the wearable space among the top strategic trends IT managers will have to contend with next year, along with big data and the burgeoning Internet of Things.

In its report, entitled “Five Urgent Truths About The Future Of Wearables That Every Leader Should Know,” Forrester expects the number of people using a wearable computer will triple in 2015, led by the highly-anticipated arrival of Apple Watch that is projected to draw 10 million users next year.

The study, which examined thousands of consumers in both U.S. and Europe, suggests more Americans (45%) can see themselves donning wearables than their European counterparts (32%).

“While wearables have indeed suffered from a hype bubble, demand for them is real. Yes, Nike’s walking away from Fuel Band, but Apple, Microsoft, Google, Samsung, and Salesforce.com all are making major commitments to the market.”

As to where consumers will likely adorn their bodies with wearable computers, many cite their wrists, clothes, shoes, ears and eyes as key areas. The report notes that the wrist appeals to over a third (42%) of consumers in both the U.S and Europe — even before the arrival of Apple’s latest device. This compared to 28% of adults last year. Gartner believes this may be a result of companies Fitbit, Samsung, Pebble, Jawbone and others that have begun educating the market about wrist-based wearables.

Meanwhile, smart garments — wearables embedded in, or clipped onto, clothing and shoes — show under-appreciated interest. In fact, fellow research firm Gartner believes the emergence of less invasive devices, particularly e-textiles will potentially disrupt the wearables space. So much so that embedded attire shipments will rise from a mere 0.1 million units in 2014 to 26 million units in 2016.

“Ralph Lauren debuted its Polo Tech smart shirt with OMSignal’s technology at the US Open, while Ducere’s Lechal uses haptic feedback to create screen-free GPS in smart shoes,” Gownder exemplifies.

Furthermore, smart earbuds, headphones and smart glasses are expected to rise in popularity. 43% of online U.S. adults have shared that they might be interested in intelligent eyewear, i.e. Google Glass, “if the price were right.”

The report also goes on to show that 10% of U.S. online adults say they’ve already used a wearable device, like a fitness tracker. However, it appears that figure will surely to rise, as nearly half (45%) of these adult consumers say they agree with the statement, “I am intrigued by the prospect of getting a wearable device.”

“And, while strong consumer interest exists for wearable devices, a bigger driver of demand is coming from businesses looking to supply employees with all types of new body gadgetry,” Reuters reports.

Take for instance, a recent Kronos and Harris poll found that 73% of workers believe that wearable technology can enhance their work environment and productivity in some way. Meanwhile, over two-thirds (68%) of business decision-makers polled by Forrester cited developing a wearables strategy for their business was now a priority.

“The wearable market will take off as brands, retailers, sports stadiums, healthcare companies, and others develop new business models to take advantage of wearables,” Gowdner urges.

Throughout the upcoming watershed year, we can expect to see the emergence of wearables to monitor the safety field workers, location-aware smartwatches to assist managers assign shift workers in real-time and video, as well as photo devices that augment the human insights of technical inspectors.

The research firm also anticipates that wearable devices will become increasingly collaborating, demonstrating how Thalmic Labs’ Myo gesture-controller armband could complement Google Glass, for example.

3DTouch is the computer mouse of the future

A pair of students at the University of Wyoming have developed 3DTouch, an intelligent device that enables wearers to interact three-dimensionally with their computers.

Dating back to the 1960s, Doug Engelbert’s mouse has dominated the way in which humans have communicated with their PCs. Though 3DTouch has an optical flow sensor that measures movement against a two-dimensional surface similar to its ancestral device, the smart thimble will now let a wearer control an onscreen mouse with a wave, tap or poke of a finger. Even cooler? Having more than one 3DTouch on different fingers facilitates multi-touch interaction.

Connected to an Arduino Uno (ATmega328) controller, the input device is equipped with a 3D accelerometer, magnetometer and gyroscope. This allows the data from each sensor to be compared and combined to produce a far more precise estimate of orientation than a single measurement alone.

This data is then streamed to a conventional laptop or desktop PC. Yet, the Maker duo are cognizant of the device’s bulkiness. “This wired connection later could be replaced by a wireless solution using a pair of XBee modules.”

The designers have tested the pointing accuracy of the new device and so far so good, claiming it’s possible to move a 3D object within an 84 x 84mm target area with a positioning error of only about 1 mm.

While 3DTouch may not the first accessory seeking to revolutionize the way we interact with our cyber world, it does possess a trifecta of unique benefits including its modularity, its flexibility in supporting multiple form factors, and its ability to open new design opportunities for the wearable interaction space. In fact, the team cites examples such as adorning 3DTouch to an index finger and using the palm of the other hand as the touch surface, or wearers interacting with curved surfaces.

“But the 3DTouch has a big advantage: price. While these other designs depend on technology that can cost anywhere from hundreds to tens of thousands of dollars, the 3DTouch relies upon sensors that cost pennies on the dollar. Even better, the thimble works just fine on today’s computers.”

So, the question is: Can this DIY device lead to the obsolescence of the computer mouse?

“[It] is designed to fill the missing gap of a 3D input device that is self-contained, mobile and universally working across various 3D platforms,” its creators conclude. “With 3DTouch, we attempted to bring 3D interaction and applications a step closer to users in everyday life.”
