Gabtronicis has updated their micro e-scopes. You may recall I did an article on them a while back. They also have a Kickstarter project to raise money to do more interesting things. Gabriel (the "Gab" of Gabtronics) likes Atmel XMEGA microcontrollers. Daishinku Corporation (KDS) has been very helpful to me with some projects I'm working on...
People simply don’t think of electric cars as long-distance vehicles. It’s a car to run down the street and grab some groceries, make the 15 miles commute to work or—like one of my friends—if you live in Hawaii and can’t really drive that far. It’s not an option most people think about for a regular car.
Here’s a rundown of the most read, most popular, most awesome articles for September. They all come with a witty, engaging summary just in case you missed them the first time or want to check up on an old favorite.

I have been big on flywheels for electrical energy storage for quite some time. So it was quite a disappointment to me to hear that high tech flywheel company Beacon Power did a Solyndra and reneged on a government loan because it could not finance its debts from income.
Part of the problem with implanted medical devices -- for example a birth control, drug delivery device like Implanon and Nexplanon -- is that eventually, they must be removed. This is proving particularly difficult with the Implanon and Nexplanon, as occasionally fibrous sheath
Space has never really interested me. When I was forced to go to a Star Trek museum at age 10 and a man dressed as a Klingon--the fictional warrior race--chased me around the gift shop, I was pretty much done with how “fun” space could be.
We’ve all seen it. You’re driving down the road and see someone driving erratically only to find that person is messing with the radio, yelling at their reprobate children, shaving, eating, or applying makeup. Distracted driving has taken on an entirely new meaning with the advent of texting.
My last column on alternative energy, A blow to wind energy, evoked more than a few complaints. For an engineering magazine writer a number of people thought that I was light on the numbers. So lets do some numbers. For that we will need a baseline. What is the cost of electrical energy in America these days? The Bureau of Labor Statistics says that the average cost of electricity in the US is 13.5cents per kilowatt hour.
Physics World reports some spectacular advances in turning graphene-based semiconductors into real-world logic chips. Graphene will do some real good for us logic guys because of its carrier mobility. It is over 140 times that of silicon. Plus its heat conductivity is about 10x that of metals like copper and aluminum, and its resistivity is about 2/3rds that of copper at room temperature.
A secret lingers behind most lighting fixtures made since WWII. Don’t tell anyone, but lighting manufacturers don’t actually make ‘lighting’ equipment. For years, fixtures have fallen into the same classifications. When it comes to fixture types, there’s the 2X2, 2X4, troffer, downlight, strip, wrap, wallpack, Type 2, Type 5, spot, flood, can and so on.
I've never thought of incandescents as dangerous contraband, but beginning September 30th, the Edison light bulb will be analogous with moonshine liquor and mind-altering drugs. Absent legislative action (which caused this mess in first place), this quintessential lighting technology faces mandatory retirement.
In our constantly changing world, corporations find themselves continually adapting to new trends and technologies, and often reinventing themselves to remain relevant. In fact, with our changing global business environment, staying the course is not an option if today’s businesses want to remain viable and competitive.
For all you random number lovers there is some excellent documentation on the www about linear feed back shift registers. LFSRs are a way to produce quasi random numbers without too much effort. Why quasi random? Well one number is excluded (all ones or all zeroes) depending in whether you use the XNOR or XOR function for computing your random number.
In today’s world we’re all guilty of multi-tasking. We talk on the phone while we drive to work. We check email while eating breakfast. We read a book on the treadmill. There are just too many things to do and too few hours in the day. Sometimes you have to be reminded to stop
In recent years, there’s been a lot of buzz about automotive infotainment systems — features that are built into recent model cars that can offer anything from satellite navigation, DVD players, internet access and more. This has led to concern from regulators about driver inattention and its impact on safety.
As a naturally clumsy person, I’m all about using technology to improve safety, whether it’s in a car or on a motorcycle. If there was a device that would beep before my knee collided with a desk, cubicle wall, low table, or other immovable object, I would own 12.
Professor Edward S. Boyden is probably one of the few individuals on the planet who is actually best described as a brainiac. Currently serving as the principal investigator at the Massachusetts Institute of Technology’s Synthetic Neurobiology Group, Boyden’s mission is to develop tools for controlling and observing the dynamic circuits of the brain.
The news that President Barack Obama's acceptance speech at the Democratic National Convention was the "biggest political moment ever" on Twitter isn’t exactly surprising, but it’s worth taking a look at how social media influences political contests.
I have been interested in computers with stack architectures for a long time. I wrote a bit about one of the latest versions at ECN a while back: Testing The GA144 Eval Board. For those of you not familiar with the subject I thought it might be a good idea to present some resource material.

As some of you may remember, I was having some trouble with the Atmel programming tools. Their Studio 6 assembler and simulator are excellent. But their chip programmers leave one or two things to be desired. Well I'm going to do the usual hardware guy solution. I'm going to hit the pins used for programming with lightning bolts.
In the run-up to the iPhone 5 unveiling next month, there is a great deal of discussion about potential new features, including an A6 SoC with quad-core structure, higher clock speed CPU and GPU, larger display with in-cell touch, higher resolution camera, and advanced OS. While it is not clear which of these features will be realized, any that are will result in higher power consumption.
Anyone who has ever lived in a city knows what it feels like to drive around attempting to find street parking before giving up and dumping the car in an expensive garage. If you frequently suffer from No Parking Spaces Syndrome (or NPSS)...
One of an editor's favorite pastimes — apart from regaling our readers with the latest products and technology — is imbibing a good adult beverage. But that could become more difficult: A new technology from the University of Patras in Greece uses thermal imaging to detect drunkenness and could prevent inebriated individuals from causing a public disturbance...
Recently we witnessed the disastrous earthquake and tsunami that has devastated the Japanese economy. The loss of life, property and infrastructure was on such a large scale, it was incomprehensible. Yet Japan was more prepared for a large earthquake than any other country. The blow that was dealt to its power generation and distribution system has the potential to delay the country’s economic recovery...
