Please don't 3D print me when I'm dead

July 23, 2014 | by David Mantey, Editor-in-Chief | Comments

When I die, please don’t grow pieces of me. Whether the practice is in the name of science, art, or engineering, after I’ve been harvested of all viable organs in my remaining vessel, do not reconstruct and 3D print any body part to be kept alive inside a case of "nourishing liquid"....

Efficiently Power that Op Amp

July 24, 2014 9:43 am | by Chris Glazer, Texas Instruments, www.ti.com | Texas Instruments | Comments

In many applications, such as temperature sensing, two supply voltages are needed to power an op amp in the system—one positive and one negative. This dual supply is needed by the amplifier in order to properly measure signals very close to or even below ground. If the negative supply input of the op amp was just grounded and a single, positive supply voltage used, these signals would not be processed properly.

Business at the expense of all else

July 22, 2014 12:38 pm | by Alan Nicol, Executive Member, AlanNicolSolutions | Comments

I would never want to believe that a business, operated by intelligent and moral people, could sacrifice quality, and even ethics, to produce a product and complete a sale. Yet recently, I witnessed a business that was so desperate to make a few deadlines, it bypassed due diligence to get a product delivered....

July 18, 2014 11:45 am | by Chris Fox, Editor | Comments

We have all come to the understanding that as 3D printing is becoming more prevalent in the mainstream consumer market, it is becoming even more ubiquitous in the engineering office (if it wasn’t already necessary). Even with this insight ...

This helmet lets fighter pilots ditch their night vision goggles

July 18, 2014 9:41 am | by Chris Warner, Executive Editor | Comments

Military jobs are synonymous with stress, but one of the most stressful jobs even by military standards is that of the jet fighter pilot. Not only are they required to process a lot of operational information very quickly, they must do it while wearing headgear that can strain the head and neck the faster the plane flies....

How to drive LEDs with power factor correction in a single stage

July 16, 2014 1:47 pm | by Brian King, Texas Instruments, www.ti.com | Texas Instruments | Comments

A PFC-SEPIC converter can be controlled using a traditional PFC-boost controller. An important characteristic of the SEPIC is the lack of isolation.  This limits the use of this topology to applications that don’t require safety isolation.  Think about applications that are completely sealed with no user-accessible energized parts, like street lights and high-bay lighting.

The first guided .50-caliber bullets

July 14, 2014 2:46 pm | by Jason Lomberg, Digital Editor | Comments

Snipers have to take numerous factors into account, including the terrain, weather, wind-resistance, and over long distances, even the curvature of the Earth — at 1,000 yards, the Coreolis Effect will alter a bullet’s trajectory by about .5 moa (Minute of angle). But until now, we haven’t been able to intentionally alter the course of a bullet....
