Alternative music group ArcAttack, as seen on NBC’s America’s Got Talent, uses Tesla Coils to make music. The demonstration video here controls the size of the charge to create sound of a certain pitch (frequency) with an NI PXIe-4844 Optical Sensor Interrogator, at a 10 kHz sample rate, and fiber-optic cable , according to National Instruments at NIWeek 2010.
Perhaps understandably, observers were asked to take a giant step backward for this demonstration.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
