When the local church needed storm effects for a skit, sound man Dick Neubert found the thunder on the Internet and added “lightning” with a photoflash strobe. He used an uncommitted output from the mixing board to trigger the strobe with the sound signal via a simple interface. The strobe places 300V across SCR1, which discharges this into the trigger coil to fire the tube. In all, this common strobe design will deliver some very uncommon effects for your next Halloween spookfest.

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.
