Q: Are there MCU that can drive a 110V motor directly, or would you interface through solid state relays?
A: A solid-state relay would be good. You could also use an MCU to trigger a triac through an opto-isolator. I have seen some schematic diagrams that use an MCU to directly drive a triac, but in the interest of safety, I'd want an opto-isolator, or opto-coupler between my MCU and line voltage. Do a Google search for microcontroller triac optocoupler.
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.
