Put Telepathy to the Test

As proved monthly in this magazine, there's pretty much no limit to the capabilities of embedded applications. How about designing a test to evaluate people who claim to be telepathic? Is parapsychology fictive? Even a skeptic can find intrigue in this project.

Tuning the Data Radio, Wireless Data Communication

The best way to know where you're going is to know where you've been. Radios may now take a back seat to pagers and Palms, but they forged the humble beginnings for wireless technology. So, take a look at the data radio when trying to solve your data transfer problem.


Don Lancaster

Steplocked Magic Sine Waves

This month, Don tackles an issue facing scores of designers. Who isn't looking for an efficient way to synthesize power sine waves? Although he won't pull a rabbit out of a hat, Don will use a little magic together with Chebyshev polynomials to get the job done.

The Missing (Wireless) Link

Sending data via wireless link can be tricky. Although there are no guarantees with an RF connection, Jeff says the keys to success are asking the right questions and knowing your system.

Liquid Crystal Delight

You have to love a product that has "easy" built right into the title. Aptly named Easy GUI, from Amulet Technologies, may be the answer to your prayers for a simple solution for middle-of-the-road LCDs.

Wireless Internet-Based Remote Control Using a Pager Interface

In this article, Bob describes a simple manner of remote control using some technologies that are time-tested, stable, inexpensive, and do not require that your house be wired to the Internet. Motorola's FLEX Stack and CreataLink receiver make it possible for your weekend retreat to be ready for your arrival with home control through the use of alphanumeric pagers. What was once thought of as futuristic is right here and now.

PDF HTML Fine Tuning an Embedded Idea

Part 1: The Land of BL2000

As article submission deadlines loomed, Fred needed an idea and he needed it fast. When he began to pluck the strings of his bass guitar, inspiration hit. Z-World's BL2000, a member of the Wildcat series, would be the next Circuit Cellar Online subject for him to explore. He's done his time with Rabbits, so cats are the next item in his wild-kingdom adventure.

Part 2: Controlling the Lights with Software

This month, James moves from the hardware details to software in the second part of his series. There are still 384 lamps, all individually controlled by only three signals from the printer port, but now you can start thinking about the applications, like Ping-Pong games, a mouse maze, simple animated scenes, fireworks, or a holiday tree with blinking lights. A bit of imagination is the last ingredient in the LiteShow recipe.

Part 4: Is the Pen Mightier than the Sword?

Way back at the dawn of the microcomputer age, Steve Ciarcia was blazing a trail (sometimes literally) through the hardware and software issues of the era. At the request of many of our readers, we've brought back a series of articles, written by Steve, chronicling the design adventures of those early days in the Circuit Cellar. This month, it's chapter one from Take My Computer, Please!

Connecting the Dots, Working with Board-to-Board Connectors

Don't be afraid to get creative with your daughterboard connector selections. This month, George takes us down a number of paths for adding a daughterboard to your design. The classic solution: chassis with backplane. With several manufacturers, good pricing, and availability, the moral of the story is to move with no fear in making that connection.

You Say Tomato

What's the difference between a mini-van and an SUV? Is it what's under the hood, or is it in the marketing? Tom tackles the distinction between DSPs and micros this month and shows us that the line is blurring between the two. Labels are inevitably misused and there are pure DSPs and MCUs, but hybrids are now commonplace. If Cadillac can make an SUV, why can't chip manufacturers follow suit?
