Bruce Field and daughter Ellie are happy campers, thanks to a portable heating/cooling device they built that maintains a constant, comfortable temperature inside their camping tent. To ensure complete climate control, they equipped a standard room air-conditioner with an electrostatic air filter, economical slinky-type dryer ducting (that minimizes number of holes cut into tent fabric), and a constant-temperature feedback sensor. An optional motion sensor discourages both curious neighbors and hungry bears.

Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
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.
