The Solar Alternative
by Ralph Lorenz
Efforts to design and construct devices for supplying renewable energy surprisingly began nearly 150 years ago, ironically, at the very height of the Industrial Revolution, which was largely founded on the promise of seemingly inexhaustible supplies of fossil fuels. Contrary to the prevailing opinion of the day, a number of engineers questioned the practice of an industrial economy based on nonrenewable energy and worried about what the world's nations would do after exhausting the fuel supply.

Universal Relay Board

by Michael Jeffery

This universal relay board will allow you to drive a 12-volt DPDT relay using heat, cold, light, dark, sound, logic-level voltages, and just about any varying resistive output sensor you can think of. In fact, you can use it to switch the relay ON or OFF using any voltage between zero to 12 volts DC or any sensor that has a varying output in this range. This is the ultimate relay board. It could even be made to run on six- or 24-volts DC with a few resistor changes and the availability of the ap Page 0

The Design Cycle
by Peter Best
A PIC-based Wi-Fi Development Platform
Does that new laptop of yours have built-in wireless Ethernet local area network (LAN) capability? How about that new portable digital assistant (PDA) you just purchased? Does it have wireless Ethernet LAN capability, too? It seems that everything these days is wireless — except the things that you really want to be wireless. Page 0

Personal Robotics

LEGO My ...
LEGO® has become something of a household word. If you grew up in the 50s or later, you probably owned a set or hoped to, in any case. It is not only a part of our culture, but also has international appeal. LEGO started out making small wooden toys in the 1930s. They slowly grew, adding plastics to their repertoire of materials.

In The Trenches
by Gerard Fonte
Project Engineering Taks
There are a series of steps that are usually followed in most engineering development cycles. It’s important to know what these are and what they entail, and this is especially true for the new engineer or new engineering business venture (independent consulting). This month, we’ll go over these basic steps and explain what they consist of and why they are important. Page 0

Open Communication

The Magic of Antennas
If you really want to know what makes any wireless application work, it is the antenna. Most people working with wireless — radio to those of you who prefer that term — tend to take antennas for granted. It is just something you have to add on to a wireless application at the last minute. Well, boy, do I have news for you. Page 0

Stamp Applications
by Jon Williams
You Can’t Touch That : Non-Contact Access Control
Okay, what’s going on with the card? You’ve probably seen them — they’re everywhere. The cards in question contain technology called radio frequency identification (RFID). Even if you haven’t heard of RFID, you may have been unknowingly exposed to it. RFID tags can be as small and nearly as thin as a postage stamp and are often used to track package movement in retail stores (big companies like Wal-Mart, Target, and others are adopting the technology). Drug companies are even putting RFID tags i
