Slideshow: CAE Goes Mainstream
CAD/CAM Corner 11/17/2011 14 comments Computer-aided engineering (CAE) features such as computational fluid dynamics (CFD) and finite element analysis (FEA) are no longer arcane tools just for highly trained specialists. They're becoming accessible to mainstream engineers via inclusion in mainstream CAD programs.
Gadget Freak Case #198: Build a Remote Fan Control
Gadget Freak 11/9/2011 11 comments Andy Morris has devised a propeller fan remote control that doesn’t require line-of-sight, which makes it easier to use in the dark. The gadget comes with off/on, three fan speeds, and multicolored LEDs to indicate the fan’s speed.
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 discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
