Converting VGA Monitors

Plain-Vanilla Monitors Become Plug-and-Play VESA-Compatible Designs

With the rapidly increasing popularity of plug-and-play capability, manufacturers want to convert their monitors into DDC-compliant ones. Peter and Shannon offer a single-chip conversion solution.


Bruce Hubbard

Image Filtering Theory

What's a Convolution Filter?

Removing noise from digital images is often regarded as a black art. Bruce discusses his mighty magic using filtration, aliasing, Fast Fourier Transforms, and convolution codes. It's all a matter of the stir.


Do-While Jones

The Global Positioning System

Part 1: Guiding Stars

Sure, you can buy a GPS receiver for less than $200, but you also need to understand them. Do-While explains positioning equations, clock accuracy, receiver design, selective availability, and differential correction.

Applying the HCS II Part 1: Of Consoles and Criminals

The joy of home automation is getting the system to give you what you need -- whether it's automatic lighting or simulated activity for those times you are away. Ken offers some tips from his own HCS II setup.

Embedded PC Development

Using Visual C++ and the Intel '386EX evaluation board, Fred has a blast showing us how Phar Lap's TNT Embedded ToolSuite is assembled and how applications interface with it. It represents the birth of a new and powerful tool.


Jeff Bachiochi

From the Bench

Tools Part 2: PCB Layout -- Time to Place the Donuts

Ever the designer, Jeff gives a helpful walkthrough of PCB layout software. You'll quickly see that modern software has brought us a long way from the old days of hand sketching and taping.


Tom Cantrell

Silicon Update

Motorola Lights ColdFire

It has the reduced instruction set of RISC but with better code density and improved cache and debug capabilities. It's in the gap between RISC and CISC. But, don't simply dismiss it as a madeover CISC or embrace it as a RISC.
