  • Connected cars: IoT’s value proposition
  • Clean up asset inefficiencies? Let us take the giant assumption that people -in mass- will accept sharing of "assets" and we get the benefit of less congestion on our infrastructure (streets, etc..) . What happens next? .. - we scale down the infrastructure to bring up efficiency? (really? just how does that happen?) - we expand the usage (with more people) till the infrastructure is overloaded (again)? Let us think at least two moves ahead .. before we declare a over simplified solution as valid. At least James touched on a few of the complexities (insurance, privacy). But the impacts go much much further into society. Change will happen.. but if it happens too quickly... can be counter productive. Revolutionary (often destructive) vs Evolutionary (often inefficient). Chose your risks carefully... Apple as a example? they are less than 20% of the total smartphones (global).. and they don't have any simple "mobile handsets" as a percentage of in the total market. Making their percentage even lower. Not quite the overwhelming presence required to rethink a portion of society's infrastructure during the course of 10 years of admittedly remarkable growth. But this is without the burdens that transportation systems have.

  • The PCB is the most important component of your design
  • Agreed. 80% of my layout time is spent on placement and making sure the schematic and pcb libraries are the way I want them. Routing? once everything is placed appropriately, it becomes the easy part. I really have a problem with schematics that are not much better than a netlist in making a design understood (a page for each component) .. so I spend some time making sure the schematic library shape is well thought out. (not just a rectangle with pins).

  • The PCB is the most important component of your design
  • Spectra autorouter.. very powerful... sorta of. It is best viewed as an assistant to your routing of a pcb. While it can operate without much guidance... I (like Paul) found this useless. To make it really work .. you had to guide the process with a "to do" list (appropriate sequence of automated sub functions) By the time I got the list REALLY optimized for a given design.. I found I could have routed the pcb myself (assuming reasonable proficiency with the CAD tools). It comes down to the amount of information specific to a design, that can be communicated to the autorouter or your pcb designer. A schematic can never carry all the information required. Biggest overlooked effort in the pcb layout process .. is the recognition a good layout needs the original engineer involved. A rephrasing of the article's title. I get it, most people want to simplify their efforts. Ironically, making the effort to be knowledgeable outside your responsibilities.. can make your life simpler. How? by making you and those around you more successful.

  • Decoupling’s effect on EMC
  • link working now.. a more comprehensive article .. but still too abbreviated for such a complex subject.

  • Decoupling’s effect on EMC
  • VELLTEC... agree. Will two more layers and additional ground planes reduce Radiated emissions..? As a generality .. yea ... sure ... But not helpful enough to determine when the additional costs become required. quote: "Engineer is a man who can do for a dime what any fool can do for a dollar."

  • Marketers talk funnier than ever
  • "Bleeding edge" technology.. as derived from "leading edge" as in first air contact on a aircraft's wing... as in: first to arrive... taken to "the next level" by incorporating some indication of pain and cost incurred to be first with a "solution". Why does blood loss .. make this sound more urgent / better to our ears? I don't understand why or how most commercials "work"... even if I can figure out what they are selling. Am I broken? Why does the creation of a new meaning to an existing word.. some how instill some new insight or truth to a noun or verb. That is so phat... Funny? .. no, just a bit sad and confused by it all. Sad because we often don't bother to learn the wonderful existing words already in our dictionaries. Diminishing the value of education. Effectively .. not learning from our past mistakes...dooming ourselves to repeating them. Promoting our own dumbing down to create a temporary feeling of being on the inside track of "knowing" a new term or TLA before our neighbor knows it?

  • Tesla's Autopilot: setting expectations ... or not
  • Brian, All this over the use of "auto" (autopilot)? Rehashing Consumer Reports attacks on using this terminology ? .. you can do better. A managed expectation cannot hope to revolve around the usage of one word. No matter what name given the technology, someone will be attempt to demand a standard of performance that cannot be achieved -ever-.. allowing some lawyer to "test" their word usage in the courts. I understand the value of managing expectations. But that is a goal that can only be applied to small groups or individuals.. not a realistic goal in large groups. Certainly you can bet Tesla's company didn't I certainly wouldn't assume Mr Brown died because of the term "autopilot" was used. Why would anyone think buying a Tesla would equate to 100% safety? This would be hubris. This doesn't happen on trains or airliners - with a LOT more effort, in a much more controlled environment and with far more resources available to prevent accidents.. why would anyone think it is possible to prevent this in any individually owned car? Of course there will be deaths in autonomous or semi-autonomous cars. No matter how far the technology advances. It will just be fewer deaths than would happen with those that can't understand the meaning of words - in the driver's seat.
