Ten Developments in 2012 - RePost

I saw this on Embedded.com and wanted to share.  Here is the link to the full article: link.

Top ten milestones in embedded 2012

- December 19, 2012

Embedded.com editors asked me to put together a list of what I feel are the ten best things that have happened in the embedded space in 2012. Rather than do that, I've compiled what I see as the ten most important things this year for embedded systems.

Number 10: Sub-$0.50 32-bit processors.
NXP and others have introduced ARM Cortex-M0 microcontrollers for tens of cents. Put a high-end CPU in your product for a tenth of the cost of a cup of Starbucks. Does this spell the end of 8 and 16 bits? I don't think so, but it does shift the landscape considerably.

Ada 2012
Number 9: Ada 2012
Ada 2012, a new version of Ada, includes design-by-contract to automatically detect large classes of runtime errors. Though Ada's use is still very small, it does offer incredibly low bug rates. In the past design-by-contract was only available natively in Eiffel, which has a 0% market share in the embedded space.

Zynq FPGA
Number 8: Xilinx acquires Petalogix, meanwhile coming out with the Zynq FPGA
The Zynq has twin Cortex-A9 cores. Zynq is interesting in that it's less about a massive FPGA and more about cores with some configurable logic. And Petalogix has a great demo showing interrupt latency on each core, one running FreeRTOS and the other Linux. Although Linux is a wonderful OS, it isn't an RTOS replacement:

Coremark
Number 7: The Coremark benchmark goes mainstream
While Coremark has been around for some time, in 2012 a number of microprocessor manufacturers have started using it strategically to differentiate their offerings. Now Coremark is even found in datasheets. ARM leveled the playing field... will Coremark upend it?

Ivy Bridge
Number 6: Ivy Bridge released
Although Intel's part is not targeted at the embedded space, their successful use of 22nm geometry, enabled by FinFET transistors, is causing the other foundries to scramble. You can be sure we'll see FPGAs at this process node before long, which will mean higher density and lower power consumption (at least on a per-transistor basis). Today both Altera and Xilinx are shipping 28nm parts.

Foxconn robots
Number 5: Foxconn plans to add 1 million robots.
Nope, this isn't happening in 2012, but that oft-reviled company is starting to ramp up their robotics. What will this mean? A ton of layoffs in China, that's for sure. It will also be a shot in the arm for those vendors who make the embedded systems that go into robots. I suspect the economy of scale will drive prices down substantially, creating more opportunities for robots there and here in the West. The impact on employment will be scary.

BIG.little heterogeneous cores
Number 4: ARM's BIG.little heterogeneous cores
If there is a theme about embedded in the last year or two, it's that of power management. It's all about the Joules when running from a battery. A smart phone demands a ton of computational capability when active, but does spend most of its time loafing. ARM mixed a Cortex-A15 with an -A7 on one die. The A15 runs when demands are high; otherwise it sleeps and the A7 runs exactly the same code while consuming less power. Other vendors have taken somewhat similar approaches, like NXP in their LPC4350 which mixes a Cortex-M4 and -M0 on a single chip.

Measuring power consumption
Number 3: Improved tools to measure power consumption of devices
To continue with the theme of power management, a number of vendors have introduced or improved tools to measure power consumption of devices. ARM's DS-5 toolchain now operates with National Instruments' data acquisition devices; Segger has a brand-new debugger that measures power, and IAR's has been improved. All three of these correlate power consumption to the running code (with some caveats). Then there are the low-cost devices like Dave Jones' uCurrent and a new-new and very innovative product I'm not allowed to talk about yet. The bottom line is that designers of low-power systems now have tools that operate in the power/code domains.

Gestures
Number 2: Innovations in gesture UIs, such as Microchip's GestIC parts
Also huge in the last few years are new ways to interact with devices. Apple refined the UI with touchscreen swiping. Kinect uses a camera to sense a player's inputs. This year Microchip introduced their GestIC parts that sense hand gestures made within 15 cm of a device. It can detect the hand position in 3D space, flicks, an index finger making clockwise or counterclockwise circles, and various symbols. And, no, as yet it cannot detect that gesture you were just thinking about.

Still waiting
Number 1: Searching..., searching....
Finally, the biggest development in 2012 is the one that didn't happen. Despite sales of hundreds of millions of multicore chips this year, no one really knows how to program them. The problem of converting intrinsically-serial code to parallel remains unsolved. Here's my six-core PC's current state as half a dozen busy apps are running:

A Positive Note...

It has been a great weekend getting the house ready for the holiday season!  On a positive note, I did read this great article from the Atlantic on the discussion of insourcing:

The Insourcing Boom

After years of offshore production, General Electric is moving much of its far-flung appliance-manufacturing operations back home. It is not alone. An exploration of the startling, sustainable, just-getting-started return of industry to the United States.
By Charles Fishman
For much of the past decade, General Electric’s storied Appliance Park, in Louisville, Kentucky, appeared less like a monument to American manufacturing prowess than a memorial to it.
The very scale of the place seemed to underscore its irrelevance. Six factory buildings, each one the size of a large suburban shopping mall, line up neatly in a row. The parking lot in front of them measures a mile long and has its own traffic lights, built to control the chaos that once accompanied shift change. But in 2011, Appliance Park employed not even a tenth of the people it did in its heyday. The vast majority of the lot’s spaces were empty; the traffic lights looked forlorn.
In 1951, when General Electric designed the industrial park, the company’s ambition was as big as the place itself; GE didn’t build an appliance factory so much as an appliance city. Five of the six factory buildings were part of the original plan, and early on Appliance Park had a dedicated power plant, its own fire department, and the first computer ever used in a factory. The facility was so large that it got its own ZIP code (40225). It was the headquarters for GE’s appliance division, as well as the place where just about all of the appliances were made.
By 1955, Appliance Park employed 16,000 workers. By the 1960s, the sixth building had been built, the union workforce was turning out 60,000 appliances a week, and the complex was powering the explosion of the U.S. consumer economy.
The arc that followed is familiar. Employment kept rising through the ’60s, but it peaked at 23,000 in 1973, 20 years after the facility first opened. By 1984, Appliance Park had fewer employees than it did in 1955. In the midst of labor battles in the early ’90s, GE’s iconic CEO, Jack Welch, suggested that it would be shuttered by 2003. GE’s current CEO, Jeffrey Immelt, tried to sell the entire appliance business, including Appliance Park, in 2008, but as the economy nosed over, no one would take it. In 2011, the number of time-card employees—the people who make the appliances—bottomed out at 1,863. By then, Appliance Park had been in decline for twice as long as it had been rising.
Yet this year, something curious and hopeful has begun to happen, something that cannot be explained merely by the ebbing of the Great Recession, and with it the cyclical return of recently laid-off workers. On February 10, Appliance Park opened an all-new assembly line in Building 2—largely dormant for 14 years—to make cutting-edge, low-energy water heaters. It was the first new assembly line at Appliance Park in 55 years—and the water heaters it began making had previously been made for GE in a Chinese contract factory.
On March 20, just 39 days later, Appliance Park opened a second new assembly line, this one in Building 5, to make new high-tech French-door refrigerators. The top-end model can sense the size of the container you place beneath its purified-water spigot, and shuts the spigot off automatically when the container is full. These refrigerators are the latest versions of a style that for years has been made in Mexico.
Another assembly line is under construction in Building 3, to make a new stainless-steel dishwasher starting in early 2013. Building 1 is getting an assembly line to make the trendy front-loading washers and matching dryers Americans are enamored of; GE has never before made those in the United States. And Appliance Park already has new plastics-manufacturing facilities to make parts for these appliances, including simple items like the plastic-coated wire racks that go in the dishwashers.
In the midst of this revival, Immelt made a startling assertion. Writing in Harvard Business Review in March, he declared that outsourcing is “quickly becoming mostly outdated as a business model for GE Appliances.” Just four years after he tried to sell Appliance Park, believing it to be a relic of an era GE had transcended, he’s spending some $800 million to bring the place back to life. “I don’t do that because I run a charity,” he said at a public event in September. “I do that because I think we can do it here and make more money.”
Immelt hasn’t just changed course; he’s pirouetted.
What has happened? Just five years ago, not to mention 10 or 20 years ago, the unchallenged logic of the global economy was that you couldn’t manufacture much besides a fast-food hamburger in the United States. Now the CEO of America’s leading industrial manufacturing company says it’s not Appliance Park that’s obsolete—it’s offshoring that is.
Why does it suddenly make irresistible business sense to build not just dishwashers in Appliance Park, but dishwasher racks as well?
In the 1960s, as the consumer-product world we now live in was booming, the Harvard economist Raymond Vernon laid out his theory of the life cycle of these products, a theory that predicted with remarkable foresight the global production of goods 20 years later. The U.S. would have an advantage making new, high-value products, Vernon wrote, because of its wealth and technological prowess; it made sense, at first, for engineers, assembly workers, and marketers to work in close proximity—to each other and to consumers—the better to get quick feedback, and to tweak product design and manufacture appropriately. As the market grew, and the product became standardized, production would spread to other rich nations, and competitors would arise. And then, eventually, as the product fully matured, its manufacture would shift from rich countries to low-wage countries. Amidst intensifying competition, cost would become the predominant concern, and because the making and marketing of the product were well understood, there would be little reason to produce it in the U.S. anymore.
Vernon’s theory has been borne out again and again over the years. Amana, for instance, introduced the first countertop microwave—the Radarange, made in Amana, Iowa—in 1967, priced at $495. Today you can buy a microwave at Walmart for $49 (the equivalent of a $7 price tag on a 1967 microwave)—and almost all the ones you’ll see there, a variety of brands and models, will have been shipped in from someplace where hourly wages have historically been measured in cents rather than dollars.
But beginning in the late 1990s, something happened that seemed to short-circuit that cycle. Low-wage Chinese workers had by then flooded the global marketplace. (Even as recently as 2000, a typical Chinese factory worker made 52 cents an hour. You could hire 20 or 30 workers overseas for what one cost in Appliance Park.) And advances in communications and information technology, along with continuing trade liberalization, convinced many companies that they could skip to the last part of Vernon’s cycle immediately: globalized production, it appeared, had become “seamless.” There was no reason design and marketing could not take place in one country while production, from the start, happened half a world away.
You can see this shift in America’s jobs data. Manufacturing jobs peaked in 1979 at 19.6 million. They drifted down slowly for the next 20 years—over that span, the impact of offshoring and the steady adoption of labor-saving technologies was nearly offset by rising demand and the continual introduction of new goods made in America. But since 2000, these jobs have fallen precipitously. The country lost factory jobs seven times faster between 2000 and 2010 than it did between 1980 and 2000.
Until very recently, this trend looked inexorable—and the significance of the much-vaunted increase in manufacturing jobs since the depths of the recession seemed easy to dismiss. Only 500,000 factory jobs were created between their low, in January 2010, and September 2012—a tiny fraction of the almost 6 million that were lost in the aughts. And much of that increase, at first blush, might appear to be nothing more than the natural (but ultimately limited) return of some of the jobs lost in the recession itself.
Yet what’s happening at GE, and elsewhere in American manufacturing, tells a different and more optimistic story—one that suggests the curvature of Vernon’s product cycle may be changing once again, this time in a way that might benefit U.S. industry, and the U.S. economy, quite substantially in the years to come.
The GeoSpring water heater—the one that just came home to Louisville from China—looks a little like R2‑D2, the Star Wars robot, although taller and slimmer. It has a long gray body, and a short top section—the brains—in gray or bright red, with a touch-pad control panel.
The magic is in that head: GE has put a small heat pump up there, and the GeoSpring pulls ambient heat from the air to help heat water. As a result, the GeoSpring uses some 60 percent less electricity than a typical water heater. (You can also control it using your iPhone.)
The GeoSpring is the kind of product we’ve come to expect will arrive on a boat from China—not much more than a curve of rolled steel, some pipes and heating elements, a circuit board, a coat of paint, and a cardboard box. And for the first two and a half years that GE sold the GeoSpring, that’s exactly where it came from.
At Appliance Park, this model of production—designed at home, produced abroad—had been standard for years. For the GeoSpring, it seemed both a victory and a vulnerability. The GeoSpring is an innovative product in a mature category—and offshore production, from the start, appeared to provide substantial cost savings. But making it in China also meant risking that it might be knocked off. And so in 2009, even as they were rolling it out, the folks at Appliance Park were doing the math on bringing it home.
Even then, changes in the global economy were coming into focus that made this more than just an exercise—changes that have continued to this day.
  • Oil prices are three times what they were in 2000, making cargo-ship fuel much more expensive now than it was then.
  • The natural-gas boom in the U.S. has dramatically lowered the cost for running something as energy-intensive as a factory here at home. (Natural gas now costs four times as much in Asia as it does in the U.S.)
  • In dollars, wages in China are some five times what they were in 2000—and they are expected to keep rising 18 percent a year.
  • American unions are changing their priorities. Appliance Park’s union was so fractious in the ’70s and ’80s that the place was known as “Strike City.” That same union agreed to a two-tier wage scale in 2005—and today, 70 percent of the jobs there are on the lower tier, which starts at just over $13.50 an hour, almost $8 less than what the starting wage used to be.
  • U.S. labor productivity has continued its long march upward, meaning that labor costs have become a smaller and smaller proportion of the total cost of finished goods. You simply can’t save much money chasing wages anymore.
So much has changed that GE executives came to believe the GeoSpring could be made profitably at Appliance Park without increasing the price of the water heater. “First we said, ‘Let’s just bring it back here and build the exact same thing,’ ” says Kevin Nolan, the vice president of technology for GE Appliances.
But a problem soon became apparent. GE hadn’t made a water heater in the United States in decades. In all the recent years the company had been tucking water heaters into American garages and basements, it had lost track of how to actually make them.
The GeoSpring in particular, Nolan says, has “a lot of copper tubing in the top.” Assembly-line workers “have to route the tubes, and they have to braze them—weld them—to seal the joints. How that tubing is designed really affects how hard or easy it is to solder the joints. And how hard or easy it is to do the soldering affects the quality, of course. And the quality of those welds is literally the quality of the hot-water heater.” Although the GeoSpring had been conceived, designed, marketed, and managed from Louisville, it was made in China, and, Nolan says, “We really had zero communications into the assembly line there.”
To get ready to make the GeoSpring at Appliance Park, in January 2010 GE set up a space on the factory floor of Building 2 to design the new assembly line. No products had been manufactured in Building 2 since 1998. An old GE range assembly line still stood there; after a feud with union workers, that line had been shut down so abruptly that the GeoSpring team found finished oven doors still hanging from conveyors 30 feet overhead. The GeoSpring project had a more collegial tone. The “big room” had design engineers assigned to it, but also manufacturing engineers, line workers, staff from marketing and sales—no management-labor friction, just a group of people with different perspectives, tackling a crucial problem.
“We got the water heater into the room, and the first thing [the group] said to us was ‘This is just a mess,’ ” Nolan recalls. Not the product, but the design. “In terms of manufacturability, it was terrible.”
The GeoSpring suffered from an advanced-technology version of “IKEA Syndrome.” It was so hard to assemble that no one in the big room wanted to make it. Instead they redesigned it. The team eliminated 1 out of every 5 parts. It cut the cost of the materials by 25 percent. It eliminated the tangle of tubing that couldn’t be easily welded. By considering the workers who would have to put the water heater together—in fact, by having those workers right at the table, looking at the design as it was drawn—the team cut the work hours necessary to assemble the water heater from 10 hours in China to two hours in Louisville.
In the end, says Nolan, not one part was the same.
So a funny thing happened to the GeoSpring on the way from the cheap Chinese factory to the expensive Kentucky factory: The material cost went down. The labor required to make it went down. The quality went up. Even the energy efficiency went up.
GE wasn’t just able to hold the retail sticker to the “China price.” It beat that price by nearly 20 percent. The China-made GeoSpring retailed for $1,599. The Louisville-made GeoSpring retails for $1,299.
Time-to-market has also improved, greatly. It used to take five weeks to get the GeoSpring water heaters from the factory to U.S. retailers—four weeks on the boat from China and one week dockside to clear customs. Today, the water heaters—and the dishwashers and refrigerators—move straight from the manufacturing buildings to Appliance Park’s warehouse out back, from which they can be delivered to Lowe’s and Home Depot. Total time from factory to warehouse: 30 minutes.
For years, too many American companies have treated the actual manufacturing of their products as incidental—a generic, interchangeable, relatively low-value part of their business. If you spec’d the item closely enough—if you created a good design, and your drawings had precision; if you hired a cheap factory and inspected for quality—who cared what language the factory workers spoke?
This sounded good in theory. In practice, it was like writing a cookbook without ever cooking.
Lou Lenzi now heads design for all GE appliances, with a team of 25. But for years he worked for Thomson Consumer Electronics, which made small appliances—TVs, DVD players, telephones—with the GE logo on them. Thomson was an outsource shop. It designed stuff, then hired factories to make much of that stuff. Price was what mattered.
“What we had wrong was the idea that anybody can screw together a dishwasher,” says Lenzi. “We thought, ‘We’ll do the engineering, we’ll do the marketing, and the manufacturing becomes a black box.’ But there is an inherent understanding that moves out when you move the manufacturing out. And you never get it back.”
It happens slowly. When you first send the toaster or the water heater to an overseas factory, you know how it’s made. You were just making it—yesterday, last month, last quarter. But as products change, as technologies evolve, as years pass, as you change factories to chase lower labor costs, the gap between the people imagining the products and the people making them becomes as wide as the Pacific.
What is only now dawning on the smart American companies, says Lenzi, is that when you outsource the making of the products, “your whole business goes with the outsourcing.” Which raises a troubling but also thrilling prospect: the offshoring rush of the past decade or more—one of the signature economic events of our times—may have been a mistake.
Business practices are prone to fads, and in hindsight, the rush to offshore production 10 or 15 years ago looks a little extreme. The distance across the Pacific Ocean was as wide then as it is now, and the speed of cargo ships was just as slow. A lot of the very good reasons for bringing factories back to the U.S. today were potent arguments against offshoring in the first place.
It was important to innovate, and to protect innovations, 10 or 15 years ago. It was important to have designers, engineers, and assembly-line workers talk to each other then, too. That companies spent the past two decades ignoring those things just shows the power of price, even for people who should be able to take a broader view.
Harry Moser, an MIT-trained engineer, spent decades running a business that made machine tools. After retiring, he started an organization called the Reshoring Initiative in 2010, to help companies assess where to make their products. “The way we see it,” says Moser, “about 60 percent of the companies that offshored manufacturing didn’t really do the math. They looked only at the labor rate—they didn’t look at the hidden costs.” Moser believes that about a quarter of what’s made outside the U.S. could be more profitably made at home.
“There was a herd mentality to the offshoring,” says John Shook, a manufacturing expert and the CEO of the Lean Enterprise Institute, in Cambridge, Massachusetts. “And there was some bullshit. But it was also the inability to see the total costs—the engineers in the U.S. and factory managers in China who can’t talk to each other; the management hours and money flying to Asia to find out why the quality they wanted wasn’t being delivered. The cost of all that is huge.”
But many of those hidden costs come later. In the first blush of cheap manufacturing, it’s easy to overlook the slow loss of your own skills, the gradual homogenization of your products, the corrosion of quality and decline of innovation. And it’s easy to assume that globally distributed production will hum along more smoothly than it often does in practice: however strong the planning, some of those shipping containers will be opened to reveal damaged or substandard goods, and some of them won’t have the number or variety of goods a company needs at that very moment. “All you need is to have to hire one or two 747s a couple times to get product here in a hurry,” says Shook, “and you lose those savings.”
Thomas Mayor, a senior adviser with Booz & Company who specializes in manufacturing strategy, says that in industry after industry, he is seeing the same kind of reassessment GE has made. When asked about the value of the original rush offshore, Mayor laughs.
“Twelve years ago, I saw a lot of boards of directors and senior executives saying, ‘Three years from now, I’m going to be sourcing $4 billion in product from China. Go figure out how to make it happen.’ ” Part of the rationale, from the start, was merely to gain a foothold in the Chinese market. And for many companies, that made sense, at least to some extent. “But if you press them on their savings by sourcing from China for North America, I get stories like ‘Oh, I asked about that six months ago. I had five finance guys working on it, and they couldn’t come up with any savings.’ At the end of the day, they say, ‘If we were doing this for the U.S. market, we should never have gone to China in the first place.’ ”
GE is not alone in moving the manufacture of many of its products back to the U.S. The transformation under way at Appliance Park is mirrored in dozens of other places, with Whirlpool bringing mixer-making back from China to Ohio, Otis bringing elevator production back from Mexico to South Carolina, even Wham-O bringing Frisbee-molding back from China to California. The Boston Company published a paper in May on ways for investors to capitalize on the U.S. factory revival. ISI Group, an investment-research company, put out a 98‑page report in August, piling up reasons for the return of a strong U.S. industrial sector. Nancy Lazar, who co-authored the ISI Group report, says, “This is the beginning of a manufacturing renaissance. I’ve been saying this since 2009. Even the industrial companies told me I was crazy. Why are they telling me I’m crazy? Because they’ve spent the last 15 or 20 years putting the plants outside the U.S. That’s over.”
The recalibration of costs in recent years is one reason, and the competitive benefit of keeping production stateside is another. But the logic of onshoring today goes even further—and is driven, in part, by the newfound impatience of the product cycle itself.
Just a few years ago, the design of a new range or refrigerator was assumed to last seven years. Now, says Lou Lenzi, GE’s managers figure no model will be good for more than two or three years. This phenomenon is not limited to GE. The feverish cycle of innovation and new products beloved in the electronics world has infected all kinds of consumer categories. Products that once seemed mature—from stoves to greeting cards—are being reinvigorated with cheap computing technology. And the product life cycle is speeding up—many goods get outflanked by “smarter” versions every couple of years, or faster.
Factories take a while to settle into a new product, a new design. They face a learning curve. But models that have a run of only a couple years become outdated just as the assembly line starts to hum. That, too, makes using faraway factories challenging, even if they are cheap.
It is not, in fact, your mother’s refrigerator anymore. The highest-end French-door fridge being made at Appliance Park retails for $3,099. Its auto-fill water spigot is unique, and it is lit inside by 10 recessed LED bulbs that use almost no energy, create almost no heat, and never burn out.
The addition of high-tech components to everyday items makes production more complicated, and that means U.S. production is more attractive, not just because manufacturers now have more proprietary technology to protect, but because American workers are more skilled, on average, than their Chinese counterparts. And the short leap from one product generation to the next makes the alchemy among engineers, marketers, and factory workers all the more important.
One key difference between the U.S. economy today and that of 15 or 20 years ago is the labor environment—not just wages in factories, but the degree of flexibility displayed by unions and workers. Many observers would say these changes reflect a loss of power and leverage by workers, and they would be right. But management, more keenly aware of offshoring’s perils, is also trying to create a different (and better) factory environment. Hourly employees increasingly participate in workplace decision making in ways that are more like what you find in white-collar technology companies.
In late 2008, Dirk Bowman and Rich Calvaruso, both manufacturing managers at Appliance Park, were looking to shake up the place, desperate to keep it relevant. Bowman oversees all manufacturing at Appliance Park. He started there 29 years ago, fresh out of college, as the second-shift foreman on the dishwasher line. Calvaruso has worked for years in manufacturing at GE, and now helps other people at Appliance Park invent and then reinvent their work on the assembly lines.
“The dishwasher line was extremely long,” Bowman says. “It went from the back of the factory to the front, and back again. It was very loud. It was very expensive—each operator was surrounded by parts, a lot of inventory. It was a command-and-control operation.” It was the kind of operation Chinese companies could readily out-compete, and the kind U.S. factory managers were happy to outsource.
Both Bowman and Calvaruso knew something about “lean” manufacturing techniques—the style of factory management invented by Toyota whereby everyone has a say in critiquing and improving the way work gets done, with a focus on eliminating waste. Lean management is not a new concept, but outside of car making, it hasn’t caught on widely in the United States. It requires an open, collegial, and relentlessly self-critical mind-set among workers and bosses alike—a mind-set that is hard to create and sustain.
In the simplest terms, an assembly line is a way of putting parts together to make a product; lean production is a way of putting the assembly line itself together so the work is as easy and efficient as possible.
“We thought, ‘We gotta try something new,’ ” says Bowman. “ ‘We have to be competitive.’ ” Calvaruso put together a group that included hourly employees and told it to completely reimagine dishwasher assembly. The group was given this crucial guarantee: regardless of the efficiencies it created, “no one will lose their job because of lean.”
So the dishwasher team remade its own assembly line. It eliminated 35 percent of the labor.
What happened to the workers who were no longer needed for dishwasher assembly? Bowman and Calvaruso created another team and asked them to pick a dishwasher part they thought Appliance Park should, once again, be making itself. The team picked the top panel of the door—appliance people call it the “dishwasher escutcheon.” It’s the part you grab to open and close the dishwasher, where all the controls and buttons are. If you use a dishwasher, you touch the escutcheon.
“The escutcheon is a high-interface part with the consumer,” says Bowman. “We wanted to control the quality. We can deliver it more easily right here. And we actually thought we could do it cheaper.” And now they do.
That’s how the outsourcing cycle starts to turn. Once you begin making the product itself, you get the itch to make the parts, too.
The dishwasher’s initial assembly-line redesign was a primitive version of lean. The full-blown, sophisticated version has spread across Appliance Park, into the work of the engineers, the designers, the salespeople, the bosses. Another team took a design for a new dishwasher into a room and pulled it apart. As originally designed, the door had four visible screws. The marketing people on the team wanted the door to have no visible screws—they wanted it iPhone-sleek. The operators loved that idea—four screws is a lot of assembly-line work. The engineers and designers came up with a design that holds the door together with one hidden screw and a rod.
“It’s easier to assemble,” says Calvaruso. “It’s cheaper. And the fit, feel, and finish are better.”
If the people who design dishwashers sit at their desks in one building, and the people who sell them to retailers and consumers sit at their desks in another building, and the people who make the dishwashers are in a different country and speak a different language—you never realize that the four screws should disappear, let alone come up with a way they can. The story of the four disappearing screws on that dishwasher door is why Jeffrey Immelt has the confidence to spend $800 million to bring Appliance Park back to life.
At the public event in September, Immelt captured the lessons of the new Appliance Park. “I think the era of inexpensive labor is basically over,” he said. “People that are out there just chasing what they view as today’s low-cost labor—that’s yesterday’s playbook.”
GE is rediscovering that how you run the factory is a technology in and of itself. Your factory is really a laboratory—and the R&D that can happen there, if you pay attention, is worth a lot more to the bottom line than the cost savings of cheap labor in someone else’s factory.
Outsourcing and the disappearance of U.S. factory jobs were the result of what often seemed like irresistible market forces—but they were also the result of individual decisions, factory by factory, spreadsheet by spreadsheet, company by company.
Appliance Park will end this year with 3,600 hourly employees—1,700 more than last year, an increase of more than 90 percent. The facility hasn’t had this many assembly-line workers in a decade. GE has also hired 500 new designers and engineers since 2009, to support the new manufacturing.
GE’s appliance unit does $5 billion in business—and today, 55 percent of that revenue comes from products made in the United States. By the end of 2014, GE expects 75 percent of the appliance business’s revenue to come from American-made products like dishwashers, water heaters, and refrigerators, and the company expects that its sales numbers will be larger, as the housing market revives.
What’s happening in factories across the U.S. is not simply a reversal of decades of outsourcing. If there was once a rush to push factories of nearly every kind offshore, their return is more careful; many things are never coming back. Levi Strauss used to have more than 60 domestic blue-jeans plants; today it contracts out work to 16 and owns none, and it’s hard to imagine mass-market clothing factories ever coming back in significant numbers—the work is too basic.
Appliance Park once used its thousands of workers to make almost every part of every appliance; today, every component GE decides to make in Louisville returns home only after a careful calculation that balances quality, cost, skills, and speed. Appliance Park wants to make its own dishwasher racks, because it can, and because the rack is an important part of the dishwasher experience for customers. But Appliance Park will likely never again make its own compressors or motors, nor is it going to build a microchip-etching facility.
And of course, manufacturing employment will never again be as central to the U.S. economy as it was in the 1960s and ’70s—improvements in worker productivity alone ensure that. Back in the ’60s, Appliance Park was turning out 250,000 appliances a month. The assembly lines there today are turning out almost as many—with at most one-third of the workers.
All that said, big factories have a way of creating larger economies around them—they have a “multiplier effect,” in economic parlance. Revere Plastics Systems, one of GE’s suppliers, has opened a new factory just 20 minutes north of Appliance Park, across the Ohio River in Indiana, and has 195 people there working in three shifts around the clock. The manufacturing renaissance now under way won’t solve the jobs crisis by itself, but it could broaden the economy, and help reclaim opportunities—and skills—that have been lost across the past decade or more.
It’s possible that five years from now, everything will have unraveled—that the return of factory jobs will have been a temporary blip, that Appliance Park will be closed. (Business practices, after all, are prone to fads.)
But that doesn’t seem likely. Bringing jobs back to Appliance Park solves a problem. It is sparking a wave of fresh innovation in GE’s appliances—every major appliance line has been redesigned or will be in the next two years—and the experience of “big room” redesign, involving a whole team, is itself inspiring further, faster advances.
In fact, insourcing solves a whole bundle of problems—it simplifies transportation; it gives people confidence in the competitive security of their ideas; it lets companies manage costs with real transparency and close to home; it means a company can be as nimble as it wants to be, because the Pacific Ocean isn’t standing in the way of getting the right product to the right customer.
Many offshoring decisions were based on a single preoccupation—cheap labor. The labor was so cheap, in fact, that it covered a multitude of sins in other areas. The approach to bringing jobs back has been much more thoughtful. Jobs are coming back not for a single, simple reason, but for many intertwined reasons—which means they won’t slip away again when one element of the business, or the economy, changes.

Smart Grid + Smart Energy + You

Whenever I talk to engineers about Smart Grid they get a cynical look on their face.  A lot of people feel that the name is marketing gimmick that doesn't hold any weight on actual products being produced.  And to be quite honest, I often agreed.  If we are not working in the smart grid space it became difficult to see the progress that has been made because we don't see the effects on our everyday lives.  One of the marketing stories we were told was that we were going to have energy readouts on all of our appliances in our homes.  While this has not happened for most of us, I did spend some time in California this week learning more about where it does apply. 

First off, I learned about the US power distribution systems and we looked at the various age of distribution equipment.  On average most of the infrastructure is 30-40 years old and only has a lifetime of about 40 years.  In addition to aged equipment there also has been a rise in demand and complications in dealing with smart energy sources like wind and solar farms.  The 40 year old power grid was generally constructed in a star topology and we have learned a lot in the past 10 years about how to handle external generation sources besides a typical power plant. 

Secondly, I learned where we are seeing innovation for a smarter grid.  The most obvious is in the energy meters outside our house.  These have been getting more accurate and have been able to communicate demand response in a more effective way to the distribution centers.  You can learn more about demand response and the impacts that this provided here. In addition to smarter meters we have also seen smart grid applications at commercial installations and server farms.  In large server farms like Google and Facebook they realize that their business is not only founded on their programmers but also how efficiently they use power.  Energy measurement has been growing in these industries to get to a higher page hit / watt ratio.  Finally the third area that we may not realize smart grid is taking hold is in the distribution of power.  From re-closers, to power pole fault indicators, we are seeing applications where it is important to measure the energy and do something with that information.  As our grid gets more complicated these preventative indication measurement devices become even more important.

So the final question is how does the smart grid affect you?  Any other good examples I missed? After getting to see some of these designs and installations up close and personal in California I definitely see that there is reality behind the smart grid.

A Day Made of Glass

I saw this futuristic video on YouTube and thought I should share.  Corning did a video explaining how they see glass fitting in our lives.  One of the great aspects of this video was that there was a lot of technology integrated into the glass.  Check out the YouTube:

Bluetooth Low Energy

I was told this week that the Bluetooth Low Energy Developers Handbook has been published.  You can buy the book now on Amazon at the following link: LINK

So what's the big deal with Bluetooth Low Energy?  Well, from my perspective, it enables deeply embedded devices a way to expand their processing powers by taking advantage of someones smart phone processing power.  It is the first standard that allows us to have data exchange with the newer Apple mobile devices.  Data exchange was possible with Bluetooth Classic in the past but you had to have a Made for iOS (MFi) chip in order to be granted licensing with Apple.  Well with the Bluetooth Low Energy devices this is no longer the case. 

Other suppliers of consumer software and hardware are jumping on board as well, but there seems to be some controversy.  I know a lot of people are frustrated with Google and not saying if/when a unified standard will be coming out for Bluetooth Low Energy.  I love checking out the post on this subject, it gets more and more hits every day. The OEMs are also struggling to find out how to incorporate Bluetooth Low Energy.  Motorola seems to understand that there customers want this and so they created an API to support devices but it is not a unified API that can be used by the Android community. 

In my opinion we need Bluetooth Low Energy support on all mobile devices.  It makes it very valuable for the embedded devices I work in on a daily basis.  We can then use the mobile smart phones that have this technology in them to offload the processor, data management, and network routing.  Most new smart phones coming out have the hardware to support Bluetooth Low Energy, but yet it appears the software on both the Android and Windows platforms that seems late to the party.  Hopefully they can catch up.

Do you see Bluetooth Low Energy as useful for your applications?

A Challenging Design Project

What if you could design, build, and then drive away in your own car?  I was intrigued by a company in Arizona doing just that.  They are called Local Motors and I thought I would share a video outlining how the company works.  It sounds like building your own car can range upwards of $75k but the experience is worthwhile in the knowledge that you learn.  Thanks Dave for the post suggestion:

Build a yeast stir plate

I hope everyone had a great Thanksgiving!  I had family over and was able to spend a lot of time with them.  No one in my family practices engineering so we used our extra time to build a hobby project for my brother.  My brother brews his own beer, and unlike my small operation, he is getting more and involved in the art of beer.  He saw a stir plate to mix his yeast online and said that he wishes he could build something like that.  As soon as I saw what he was trying to build, I said, we can do that.

It was a lot of fun to build a project with my brother.  In fact, I built most of the device with spare parts from around my house.  Here is the article on how to build a stir plate from stirstarter.com :

Instructions

Interested in building your own stir plate? It's a tinkerer's dream and easily accomplished as a weekend project. Using parts accessible to most, a functional stir plate can be constructed in just a few hours. The parts you'll need to gather are:

· Computer fan

Most computer fans are of the 12 VDC variety. Any size will do, I use an 80 mm fan

· Rare earth magnets

These can be harvested from dead hard disk drives. A good source if you need to purchase your own is www.magnet4less.com

· Stir bar

You don't need a giant stir bar! A 1" bar works fine. Single bars are available on eBay or get bags of ten from www.stirbars.com

· Flask

Get a 1- or 2-liter flask, a good place to buy is www.cynmar.com

· Electronics for voltage control : potentiometer, 2,000 ohms ; LM317 voltage regulator ; resistor, 330 ohms ; capacitor, 0.1 mfd

Radio Shack is a good place to get single piece parts like this. Since I buy lots of these parts, I go to www.mouser.com. I have seen some designs that use just a pot for speed control. I don't recommend this. At low speeds, you are using the potentiometer to drop the full voltage from the power supply which could be several watts. Most pots are designed to dissipate ¼ to ½ watt. They won't last long operating like this.

· Plug in power adaptor

This adaptor can be anywhere from 9 to 12 volts DC, capable of delivering at least 200 mA continuously. The stir plates I build draw about 100 mA. The current requirements of other fan motors may be larger, but 200 mA should do.

· Stub of 1” PVC pipe

Use this as a spacer between the drive magnets and the hub of the fan. Attaching the drive magnets directly to the fan hub will interfere with fan operation and torque. A ¾” PVC coupler also works well.

· Enclosure

Any non-metallic box will work but it should be around 2" deep so you can mount the fan to the bottom of the enclosure instead of trying to “hang” it from the cover with long machine screws.


Tips and hints for construction and operation:


* It's important for the drive magnets be as close to the stir bar as possible for good coupling. This is where the PVC spacer serves as a useful way to stand off the magnets from the fan hub and get them as close to the lid of the enclosure as possible. Measure and cut the spacer carefully, and you'll get the drive magnets up close where they belong.
* You don't need to develop a “Wizard of Oz” vortex in your starter to get good results. A 1" or 2" dimple in the liquid is all that's needed. The deep vortex you see in some of the YouTube videos is fun to watch, but not necessary.
* The distance between the poles of the drive magnets should be as close to the dimensions of the stir bar as possible. If you are using a 1" stir bar, the poles of the drive magnets should be about 1" apart. This is easy if you use two button magnets like I do. You can adjust the distance between the two button magnets for best stir bar stability.
* Don't fill your flask all the way up to the neck with starter wort. Aeration is important for yeast propagation, so try to keep the surface area of the starter wort high. Fill a 2-liter flask with no more than 1.5 liters of wort, for a 1-liter flask, use no more than 750 mL of wort.
* Don't use a stopper and airlock on your flask as you stir. This defeats the whole purpose of aeration. Just keep a loose foil cap over the neck of the flask to keep dust borne bacteria out as much as possible.

Cultivating Creativity with Gener8tor

Milwaukee is encouraging innovation through the group Gener8tor.  Look at some of the ideas coming from their launch party.  This article is taken from the Milwaukee Journal.  Nice work Milwaukee!

Gener8tor holds launch party for 7 companies

Mayor Tom Barrett, state legislators, financiers and others were among more than 300 people who attended a launch party for seven new companies Thursday night at Discovery World in Milwaukee.
The companies recently completed a 12-week class at Gener8tor, a for-profit Milwaukee group that works to help chosen start-up companies identify customers and accelerate their growth. Potential investors evaluated the companies' presentations and in coming weeks will make decisions about whether to invest in them, said Joe Kirgues, a Gener8tor co-founder.
"All of the companies were very well prepared," said Chris Schiffner, technology investment manager at the Wisconsin Economic Development Corp. "Obviously the experience they had in the class prepared them for presenting to investors and helped them put together great business plans and models for moving forward."
The companies showcased at the launch party had potential - but even more important, the event showed that Milwaukee and other areas of the state are putting time and energy into young companies, which will be the job creators of the future, said Mark Ehrmann, a partner in Quarles & Brady's Madison office who works with emerging companies and their investors.
The state needs organizations like Gener8tor that support young companies in order to compete with other cities such as Chicago that have big accelerator programs, Ehrmann said. Many of the companies presenting at Gener8tor's launch party were run by younger entrepreneurs.
"If we can keep their companies in Wisconsin, it will help the state immensely and help stem the brain drain," Ehrmann said. "Some of these companies will create significant job growth."
The seven start-ups were: Uconnect; Mobile Igniter ; The Good Jobs; Subsidence; Swapferit; SpanDeX; and Date Check Pro.
This was the first launch party held by Gener8tor, which was formed in February by Dan Armbrust, president of Granite Microsystems, and other partners. Kir gues and Joel Abraham, both formerly of 94labs, are also founders.
Gener8tor provides seed investments of nearly $20,000 to start-ups selected from a competitive application process, plus its expertise, mentorship, community and network, Kirgues said.
It is modeled after Y Combinator, a start-up accelerator in the Silicon Valley that was started by Paul Graham in 2005. Gener8tor recently said American Family Insurance has become one of its partners.

SEG Market - What a shopping experience

I saw this video on the ultimate electronics shopping experience.  I can't imagine having the ability to have on demand access to components like this:


If you don't have time to check out the video, I reposted the content from DangerousPrototypes.com:



SEG market is the best known electronic part market in Hua Qiang Bei neighborhood. It’s two giant floors of component and tool stands. The upper floors are full of computer parts and consumer electronics, also very cool, but we’re here for the electronics.
This is an overview of the second floor of SEG Market. It’s not as crowded and narrow as the 1st floor. Check the ultimate stop on our Global Geek Tour below the break.


Small glass display cases with sample components line each isle of the market floor. If you ask to see a component the shop owner slides open the top and pulls it out. Sample quantities are usually available for immediate sale, but larger quantities of many things are couriered from somewhere nearby in 5-10 minutes.
Stands represent distributors or factories. There’s lots of stands with the exact same thing, either from competing manufacturers or distributors. Parts like switches, pin headers, coin cell holders, pogo pins, programming adapters, and LEDs are all sold like this.

Stands with wire piles do custom cable assembly. The stand on the right is numbered 2368. Each stand has a business card with its number to help you find it again.

Each stand has a card. Take the card and write down the price of stuff you like. Use the stand number printed on the card to find your way back later.This stand has bundles of cold cathode tubes.
Tully, one of our guides, said it was more important to build a relationship than bargain. Once you have a relationship the price is the same for 1 or 1000. This in mind, on the second day we also gave our card, which was accepted graciously by everyone.

Breakout boards for potted chips. These are the kind of low cost chips you see in calculators and watches, they bond directly to the PCB. This stand has breakouts for several dozen.

The ultimate selection of programming adapters. SOIC, SSOP, QFP, QFN, even 10×10 ball grid arrays! Unfortunately nobody was there to give us prices.

You need magnets? We got 1000 for about two bucks.

This shop was well equipped with all kind of programmers and development boards. Notice the number – 2860 – this is printed on the business card too so you can find it again.

Part displays get creative. Most stands are run by salespeople, not engineers.

Despite the six floor market dedicated to LEDs across the street, SEG Market also has all kinds of LED and LED sign shops.

A stand with two dozen different microscopes. We bought the USB version of this scope. Look for a review later today.

Checking out a photography light box. The SEG price was half of the Hong Kong price, and exactly the same as on TaoBao (the Chinese eBay).

On the 3rd and up to the 10th floor there were more shops, but unfortunately no more component shops, only consumer electronics stores. Prices on components beat anywhere else, but a lot of the consumer electronics are more expensive than in the US.
Lets move on to the next component market!

What SEG Market looks like from the outside.

A Good Offer

I was introduced to a great deal yesterday that I wanted to share for all my hardware and software friends out there.  If you are using a Real-Time Operating System today you probably recgonize the name Micrium with their uC/OS operating system versions.  They have just paired up with Renesas and are offering their kernel for free, middleware for free, and one year of support if you use a Renesas RX or RL78.  If you use all the middleware components that is estimated to be greater than a $100k value.  There are some stipulations to the deal (such as it must be for a commercial product), but if you are looking for a quick way to get started on a 16bit or 32bit microcontroller this might be a way.  Check out the post to learn more:

Brewing Beer with MSP430

One of my hobbies is brewing beer, check out how one engineer made a simple control system to automate some of the process:

A MSP430 Double-Kettle Electronic Brewing System


Dave brews beer at home on a stove, but waiting and standing for water to boil takes most time and fun out of it. He came up with an improved automated system with an electric brewing system. A MSP430 Launchpad commands solid state relays which control  5500W heating elements which significantly reduces boiling time to 15 minutes for 5 gallons.
A zip file on his Element14 blog post has schematics, BOMs and documentation.

A Large Box of Fry's Please!



So we are not going to talk about fast food today, but some of my favorite electronic stores for hobbyist electronics.

I have started to accumulate my collection but it definitely is a slow process.  First off, I have to secretly hide my purchases so my wife cannot see the amount of new stuff I am buying.  Secondly, I am starting to already run out of room.  I plan to someday build a larger lab, but for now it is two folding tables.  I use one as my rework / teardown station and the other as my debug station. 

When I was in college I could visit the Radio Shack or our school's EE lab and buy all the discrete components I needed (This also explains why my designs were so simple).   One of my first projects was to create a stopwatch using standard logic parts.  I was able to source all the components right from the Radio Shack next to my apartment.  Now, as box stores have declined, I have noticed that the number of electronic stores carrying parts has also been on the decline.  Radio Shack still has the sliding shelves of components but the inventory is never as plentiful and the variety is never as diverse as what it once was.  Perhaps my perception is skewed because my interests have also moved to more complicated parts that would not be able to be purchased there anyways.

On one of my recent trips to Texas, I went with a friend to a store I wish we had in Wisconsin - Fry's Electronics.  For those of you that don't have one in your area, I highly suggest a field trip to a local store near you.  I felt overwhelmed, excited, and wish I had more time to spend navigating the aisles of components.  So if Fry's is reading this post, please keep me posted if you plan to build in Wisconsin because you definitely have a customer. 

Today the majority of my components are sourced from the web.  I use AvnetExpress for all my components and evaluation kits.  I also have been known to hang out on Ebay and look for that great mega-deal (like the 10000 piece resistor packs).  For other design tools and supplies I have used Amazon and SparkFun.  Are there any other good sites I should be checking out?

Getting Political with Electronics

Happy Election Day America!  I woke up early this morning and it made me reflect on the sacrifice of the men and women who have and are still making America great.  No matter what political views we hold it makes me proud to be able to cast my vote.  But before I go into a political rant (which I will always avoid in my posts), let's turn the discussion over to electronics.

We have started to see electronic voting in America. Unfortunately these systems have not had the best press because people have found ways to hack into them.  While many companies make great products that are not hacked, it only takes one incident to raise questions about the integrity of their electronic voting system.

However as I stood in line, I wondered, will we see the voting system go purely electronic?  Can we stay at home, log into the web, and cast our vote in the future?  As a technology guy, I only see the system moving towards that direction.  However, it is a great feeling waking up early, sitting out in the cold, and casting your vote with your fellow Americans.

Thanks to everyone who has served our country!
