Raspberry Pi to narrow Digital Divide?

The effort to close Digital Divide — the separation between those who can and can’t afford access to the Internet — has been a point of frustration for government and social activists for more than a decade. However, the rousing success of the Raspberry Pi computer launch on Leap Day could significantly close the Divide with the right price point and distribution strategy and punch a hole in commercial efforts to derail low-cost computing.

The United Nations established the World Information Society Day (May 17) for the first time in 2001 and since then there …



The roads less traveled around multicore walls

A New Tech Press Report from Footwasher Media

For the better part of two decades, the processor industry has been running pell mell down the road of multicore design, packing more and more processor cores on a single chip.  But a funny thing happened on the way to the personal super computer.  It didn’t work.

In 2007, a DARPA study on the potential of an exascale computer concluded that with the current architecture of processors, in other words x86 and PowerPC, we could not get there from here.  As a result, in January 2012, …



Apple TV won’t be AppleTV.

Nov 30th, 2011 | By

The growing relationship between Sharp and Apple that was revealed last week put to bed conjecture whether Apple’s next leap might be into television.  It is.  And that leaves an open question:

Has Apple gone mad?

The profit margin on TV’s is razor thin at best. In 2007 the average screen sold for $982; this year it’s $545 and, in many cases, TVs are a loss leader for electronics retailers (you make money on the cables, you know).  Apple has always been about margin and their phones, computers and tablets have had a much higher profit then just about anyone …



Can Solar survive Solyndra aftermath?

Solar industry is feeling much better now.

The recent collapse of a few high-profile solar energy companies, like Solyndra and Beacon Power, has caused even the most ardent fans of alternative energy to ask, “Can this industry survive?”  The answer is a resounding, yes and no.  It all depends on what government on all levels does.

Current public impressions of the health of any industry are colored by recent history.  The financial failings of companies and industries considered “to big to fail” are what most people think of when hearing news about …



imPARTing Knowledge 3: Understanding Component Engineering – Microcontrollers

Many small board designs benefit nicely from the use of a microcontroller.  But selecting an appropriate one for a particular design often brings on the feeling of “Where do I begin?”

This discussion limits its focus to low-end microcontrollers.  For this purpose, we’ll stick with 8-bit devices.  8-bits simply means that internal processing only operates on 8 bits at a time.  As one would expect, 16- and 32-bit micros would operate much faster as they are processing more bits of data with each instruction.  To be sure, much of the same thinking …
