Also, on using the lower power chips on two batteries (at 3 volts) if they will run OK, they may run slower. See data sheet. TI MSP430s will run down from 1.8 to 3.6 volts, but the processor speed will slow down with lower voltages. Check the specs to ensure you will get the proper speed at the voltage you want to run (and test it at the actual voltage too)
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.
