@Carol, slide 6 from the first day says 'The HV9910DB3v.3 can supply a maximum output current of 900mA to drive LED strings from a 9VDC to 30VDC input.' I think you're right that the demo board has a 35V cap on input which limits Vin. Just checking.
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.
