How to manage creative types (with a minimum of fuss)
April 17, 2013 1:14 pm | by M. Simon, Technical Contributor | CommentsThe First Mate and I were discussing this Harvard Business Review article the other day, and I noticed a lot of allusions to myself. The article is about how to manage creative types. There are seven main points (numbered), but I'm only going to comment on a few.
Creating a QFN footprint - the center pad
April 17, 2013 10:30 am | by Screaming Circuits | CommentsI've written bits and pieces about creating footprints in Eagle and a lot about what the QFN solder paste layer should look like, so maybe it's time to connect the two dots. I'm using Eagle CAD here, so your process will likely be different unless you're using Eagle, but the concept should be the same.
DoD cancels “participation trophy” for drone pilots
April 16, 2013 4:03 pm | by Jason Lomberg, Technical Editor | CommentsThe DoD has finally backed down. And I applaud their decision. Following months of negative feedback, the DoD has officially scuttled the Distinguished Warfare Medal. The DWM — intended for drone operators — would’ve ranked ahead of the Bronze Star and Purple Heart (two combat decorations) in the order of precedence.
Why the government should ban cellphones while driving
April 16, 2013 10:28 am | by Kasey Panetta, Managing Editor | CommentsThis term “nanny state” is an interesting one. It’s a term people throw out when they feel the government is infringing on their right to do something stupid. Frankly, if people could be trusted to police themselves, we wouldn’t have any laws at all.
Low-cost IQ modulation with true-form waveform generators
April 15, 2013 1:37 pm | by Joan Mercade, Arbitrary Resources, S.L | CommentsDigitally modulated signals fill space and travel through almost every wired and optical network. Today, almost all wireless services use a plethora of complex carrier modulation schemes. The continuous improvement in modulation technologies and components and advances in error-correction codes have increased channel capacity close to the fundamental limit as set by the Shannon-Hartley theorem.
We all need Google Fiber
April 15, 2013 1:16 pm | by Joel Hans, Managing Editor, Manufacturing.net | CommentsAlmost a year ago, Google launched its first broadband internet network, Google Fiber, in Kansas City (the Kansas and Missouri versions both), with speeds that severely overshadowed currently-available cable and DSL providers for a fraction of the cost. Consumers were able to sign up for 1 gigabit download speeds for a mere $70 a month.
Computers are the new Freud of dreams
April 15, 2013 9:25 am | by Stephanie Carmichael, Contributor | CommentsWe use computers for just about everything: communicating, avoiding long lines at the mall, and even ordering pizza. Thanks to new research, their presence is extending beyond our waking lives. It might sound like something out of science fiction, but scientists have discovered a way to use computers to read people’s minds.

Silicon Valley has nothing on manufacturing
April 12, 2013 5:45 pm | by David Mantey, Executive Editor, PD&D | CommentsManufacturing floors don’t have Lego stations and pool tables — and yes, OSHA may take issue with throwing empty cans from the mini bar into the same bin as the scrap metal from the lathe, but that doesn’t mean that the industry has any fewer engineers flocking to it.
Iran invents “time machine,” beats Doc Brown to the punch
April 12, 2013 10:23 am | by Jason Lomberg, Technical Editor | CommentsFrom the same folks who brought you the flying clown car comes this: An Iranian scientist claims to have invented a time machine. No, really. I cannot make this stuff up. Ali Razeghi registered "The Aryayek Time Traveling Machine" with the state-run Center for Strategic Inventions. He claims it can "predict five to eight years of the future life of any individual, with 98 percent accuracy"....

The nanny state should loosen its grip on cell phones
April 11, 2013 3:24 pm | by Jason Lomberg, Technical Editor | CommentsWe’ve written a lot on ECN about automotive safety and its intersection with cutting-edge technology. Texting, Facebooking, and web surfing pose an existential concern for distracted drivers (not to mention pilots, train conductors, and boat captains), but the nanny state has really overreached on this one: A California court recently found a motorist guilty of distracted driving for checking a map on his iPhone.
Legos on the plant floor?
April 11, 2013 2:25 pm | by Joel Hans, Managing Editor, Manufacturing.net | CommentsWe’ve all probably heard about the incredible perks that Silicon Valley technology companies give their employees.
