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
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
