This first-aid kit is a must-have

July 31, 2014 8:55 am | by Kasey Panetta, Managing Editor | Comments

The Clever Medkit is a first-aid kit to end all first-aid kits. This over-the-top technologically advanced kit is technically designed for businesses, but I would consider this for a home purchase because I am a germaphobe and hypochondriac. (Yesterday, I used a Lysol wipe on my pens.) So, let’s walk through the process of injuring yourself and using this bad boy.

July 28, 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.

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.
