Al Linke's tiny breathalyzer is stored in an Altoids box, and the results can be sent to his Android phone. The key component is the IOIO board, which enables the Android to receive data from eternal sensors.
Interesting little app, although I wonder if the people who would actually need it, would actually use it.
The question I have is about it's accuracy and repeatability. It doesn't look like it actually reports a number just one of 3 ranges. This is probably a good thing so we don't have people splitting hairs. But if the limits aren't quite calibrated correctly I can see a liablity issue (even if its free) if someone is busted for DUI and this thing didn't tell them. Yes, I know that that is not the purpose of it or how it is SUPPOSED to be used, but I also know that those who might be needing this on a regular basis won't care.
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.
