For Greg Ruhlander's complete instructions on how to build your own computer keyboard with integrated am/fm radio, click here.
Unable to function without his trusty portable am/fm radio at his side—especially while working—Greg hit upon the idea of integrating it directly into his computer's keyboard. The big plus is no batteries required since the keyboard powers the radio. Taking a standard keyboard and small, portable radio, he designed a simple voltage reduction circuit to step down the keyboard's 5V to 3V, and there you have it: a convenient combination of two items or a boombox for geeks.

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.
