NI WEEK 2010
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.

Warping a telescope lens to match atmospheric distortion: A new European ground-based telescope uses NI-based parallel computing connected via a high-bandwidth backplane (via PXI System Alliance) to quickly adapt the lens to atmospheric distortions. The demo simulates atmospheric distortion with a flame, collecting 500 high-resolution frames per second through machine vision, into an FPGA into four rack-mounted controllers that instruct more than 1,000 actuators how to change the 42 meter diameter telescope lens, all in less than 2 milliseconds, explained Patrick Webb, NI PXI Systems, product marketing manager. The computational equivalent of 64 interconnected computer nodes could control and balance 320,000 inverted pendulums. Just 5 years ago, balancing one pendulum was an impressive demo, Webb said.
Beer fridge security system, with power and temperature monitoring, incorporates Bluetooth wireless temperature sensing, Compact DAQ, and an Apple iPad or a soon-to-be released Dell Android phone as a thin-client human-machine interface. See www.ni.com/smartphone for example programs for iPad, iPhone, or Android apps, said Chris Delvizis, product marketing manager, NI R Series, intelligent data acquisition.
