Samsung Needs to Get Transparent Samsung owes its customers and the tech community a clear explanation of what happened with the lithium ion batteries in its Galaxy Note 7 smartphones. We live in an industry that operates behind closed walls. Most days corporations need to protect their intellectual property carefully, but this is not one of them. Lithium ion batteries are widely used across the industry in everything from hearing aids to electric cars. The drive for profits from the premium smartphone market drove Samsung to push the limits of how much work the thinnest and lightest of those batteries could do in a high res, multitasking consumer product. Something went horribly awry and customers and fellow engineers need to know the details. Customers deserve an answer because they implicitly trusted the company with products they put in their pockets and held up to their faces. It’s not just Samsung’s credibility at stake here; any maker of smartphones now faces the consumer backlash these phablets created. Engineers across the supply chain need to understand what happened if they are to prevent it happening again. We are a long way from any other mainstream battery chemistry at a time when the volume of smartphones, cars and other products using lithium ion are rapidly on the rise. Whatever lessons Samsung learned about these products needs to be shared with the community—with the same intensity and speed with which the products are designed and built. I applaud executives who made the hard decision to pull the Galaxy Note 7 from the market entirely. The move slashed and estimated $17 billion off Samsung’s market capitalization and could cost another $2.8 billion in quarterly losses, according to analysts quoted by The Wall Street Journal. You could argue, and plenty will, the company took too long to come to this hard decision. But I think a more important point to argue is that the best reparations should come from transparency. Samsung can refund the costs of the phone to customers and dealers, and it should. But that won’t stop the problem from happening again. In a global industry that lacks a global consumer protection agency, Samsung needs to step up to the plate. Investigate and share the flaws of the Galaxy Note 7 batteries with your customers and the technical community. It’s the right thing to do. http://www.eetimes.com/author.asp?section_id=36&doc_id=1330614&_mc=NL_EET_EDT_EET_daily_20161012&cid=NL_EET_EDT_EET_daily_20161012&elqTrackId=03ba9d11b478488abf8e3a9a4e40e22e&elq=e064bb406ec648e193aea01305bd7f71&elqaid=34324&elqat=1&elqCampaignId=29950 |

https://i66.tinypic.com/2jeql2b.jpg PARIS — It’s far from clear what exactly caused Samsung Note 7 to catch fire at this point. Samsung isn’t talking until after it finishes its own investigation. But a new report emerged Wednesday that the culprit might not be the lithium-ion batteries themselves, which Samsung initially suspected. Rather, the problem might reside in the underlying technology -- tweaks made to the processor in the smartphone. Attributing an unnamed source who has spoken to Samsung chiefs, the Financial Times reported, “Problems with the phone appeared to have arisen from tweaks to the processor to speed up the rate at which the phone could be charged.” The source told the U.K. newspaper, “If you try to charge the battery too quickly it can make it more volatile. If you push an engine too hard, it will explode. Something had to give.” After the market closed Tuesday, the Korean electronics giant announced that it would scrap its Note 7 smartphone and completely halt production. Samsung's Note 7 comes in two versions, with one using Samsung's own Exynos 8893 processor and another based on Qualcomm’s Snapdragon 820 processor. Giving some credence to the new theory — putting the blame beyond the battery itself — are explosion incidents that have surfaced with replacement phones using new batteries produced by another company. Samsung initially connected the explosions to batteries produced by Samsung SDI, an affiliate company. The Korea Herald reported that Samsung SDI supplied 70 percent of Note 7 batteries, while Amperex Technology (ATL) supplying the remaining 30 percent. Initially, Samsung did not observe the overheating issues among Note 7 using ATL batteries. Therefore, after the first recall, as a temporary solution, Samsung asked ATL to step in and supply batteries for the replacement phones. However, as it turns out, on Monday, the replacement phones with ATL batteries also started blowing up. ATL is a Hong Kong-based company established in 1999, acquired by TDK in 2005. Its production lines reportedly have been operating under strict manufacturing processes compliant to those of TDK since 2010. Did this mean that ATL/TDK batteries were also defective? Not exactly. By process of elimination, Samsung now seems to conclude that changing batteries doesn’t lower the heat. By all accounts, Samsung’s decision to cancel all production of the Note 7 indicates that the Korean giant realizes it must look elsewhere — other than batteries — to explain the alarming phenomenon of its smartphones bursting into flame. According to the information posted by the United States Consumer Product Safety Commission, Samsung has received 92 reports of the batteries overheating in the United States, including 26 reports of burns and 55 reports of property damage, including fires in cars and a garage. http://www.eetimes.com/document.asp?doc_id=1330616&_mc=NL_EET_EDT_EET_daily_20161012&cid=NL_EET_EDT_EET_daily_20161012&elqTrackId=792c2b1e66974937bb60820f2b163002&elq=e064bb406ec648e193aea01305bd7f71&elqaid=34324&elqat=1&elqCampaignId=29950 |

If you entered the world of professional computing sometime in the 1960s or 1970s there is a high probability that you would have found yourself working on a minicomputer. These were a class of computer smaller than the colossal mainframes of the day, with a price tag that put them within the range of medium-sized companies and institutions rather than large corporations or government-funded entities. Physically they were not small machines, but compared to the mainframes they did not require a special building to house them, or a high-power electrical supply. One of the most prominent among the suppliers of minicomputers was Digital Equipment Corporation, otherwise known as DEC. Their PDP line of machines dominated the market, and can be found in the ancestry of many of the things we take for granted today. The first UNIX development in 1969 for instance was performed on a DEC PDP-7. DEC’s flagship product line of the 1970s was the 16-bit PDP-11 series, launched in 1970 and continuing in production until sometime in the late 1990s. Huge numbers of these machines were sold, and it is likely that nearly all adults reading this have at some time or other encountered one at work even if we are unaware that the supermarket till receipt, invoice, or doctor’s appointment slip in our hand was processed on it. During that over-20-year lifespan of course DEC did not retain the 74 logic based architecture of the earliest model. Successive PDP-11 generations featured ever greater integration of their processor, culminating by the 1980s in the J-11, a CMOS microprocessor implementation of a PDP-11/70. This took the form of two integrated circuits mounted on a large 60-pin DIP ceramic wafer. It was one of these devices that came the way of [bhilpert], and instead of retaining it as a curio he decided to see if he could make it work. The PDP-11 processors had a useful feature: a debugging console built into their hardware. This means that it should be a relatively simple task to bring up a PDP-11 processor like the J-11 without providing the rest of the PDP-11 to support it, and it was this task that he set about performing. Providing a 6402 UART at the address expected of the console with a bit of 74 glue logic, a bit more 74 for an address latch, and a couple of 6264 8K by 8 RAM chips gave him a very simple but functional PDP-11 on a breadboard. He found it would run with a clock speed as high as 11MHz, but baulked at a 14MHz crystal. He suggests that the breadboard layout may be responsible for this. Hand-keying a couple of test programs, he was able to demonstrate it working. We’ve seen a lot of the PDP-11 on these pages over the years. Of note are a restoration of a PDP-11/04, this faithful reproduction of a PDP-11 panel emulated with the help of a Raspberry Pi, and an entire PDP-11 emulated on an AVR microcontroller. We have indeed come a long way. http://hackaday.com/2016/08/22/a-pdp-11-on-a-chip/ |

| Sports › Mourinho Refuses To Sign Chelsea Shirt (video) by princejude(op): 8:10am On Jul 22, 2016 |
The former Blues boss is still adored by sections of the Stamford Bridge faithful but has showed his loyalty to his new club during the club's pre-season tour Jose Mourinho has delivered a blow to his former club by refusing to sign a Chelsea shirt while on a pre-season tour with Manchester United. The self-proclaimed Special One won three Premier League titles, three League Cups and an FA Cup in his two spells at Stamford Bridge. A large selection of supporters also sang his name during his troubled period in charge of the Blues, before he was sacked by the club in December 2015. Now, as manager of Manchester United, the Portuguese refused to sign a Chelsea shirt presented to him during the Red Devils’ pre-season tour of China. Watch Mourinho reject the supporter in the video above! http://www.goal.com/en-ng/news/4104/video/2016/07/22/25834062/watch-mourinho-refuses-to-sign-chelsea-shirt?ICID=HP_BN_11 |

darediamond:DC - AC Inverter has operating limit. The highest frequency inverter I have seen is about 40 to 50KHz, and the final output was later stepped down to 50 - 60 Hz using pwm. The product has a lot of high frequency components such as transistors, diodes, ICs, etc which were very difficult to find in the market. You may have the design concept, but with which material?

arduino nano:Is Arduino programming language an ASSEMBLY language ? forget about C or C++ and learn Arduino programming language which was derived from C language.If you write a simple C or C++ program in an Arduino IDE will it compile or verify ? If you don't know, Arduino programming language is a C language specifically designed (i.e, with its syntax) for Arduino hardware. He is not limited to arduino programming and may still venture into other MCU hardware programming in the future and knowing C gives him comparative advantage.Other MCUs have their different C syntax and compilers, so if you want to program them, get their materials on C programming and learn' |
