Hardware Engineer Gustavo Castro gets down on stage
A hardware engineer jamming on stage isn't exactly what you'd expect at a
Technical Conference. So that may be why Gustavo Castro's rendition of "Smoke on
the Water" nearly brought down the house at Tuesday's keynote address at NIWeek
2004. Plus, he's good. Castro, who played a major role in adding new features to
NI's PXI-4070 FlexDMM, a 6 1/2-digit high-speed digitizer for PXI,
combined his engineering and musical skills to showcase the 4070's new
inductance and capacitance measurement capabilities (http://sine.ni.com/apps/we/nioc.vp?cid=12683&lang=US).
Essentially, he created a guitar tuner (albeit a pricy one!), exploiting the
digitizer mode of flex DMM by measuring the inductance of the guitar pickup and
capacitance of the cable and pre-amp, digitizing the output waveform, and tuning
the guitar using LabVIEW. And by the way, Gustavo and his rock band, The Happy
Fun Ball, get down on Friday nights on Sixth Street here in
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
