8 John Gorsky	New Product News ConnexLink wireless transceivers from AeroComm, Inc. ADAM 652x 10/100BaseT Ethernet switches from CyberResearch, Inc. B82789XX series CAN bus chokes from EPCOS, Inc. Medallion 38-000010-xxx compact industrial computer from Technical Solutions, Inc. R108 HyperCore 8051-based core module from R2 Controls, Inc. Linux Development Kit for IXP425 Xscale-based network processor from Arcom Traversix Connectivity System managed remote access service from Wavetrix DS139x family of real-time clocks from Dallas Semiconductor AR-B1551 3.5" EBX CPU board with NS GeodeT 300-MHz processor from Acrosser U.S.A.
15 David Tweed	HTML Test Your EQ
16 Eric Gagnon	Simple Four-Channel Network Video Server Eric recently built a video surveillance system to monitor his property when he isn't home. He saved a lot of money by incorporating a four-channel network video server rather than expensive IP cameras. The video server, which Internet-enables four conventional NTSC cameras, provides a standard Ethernet network interface. Download: Gagnon172.zip
24 Ingo Cyliax	HTML Wi-Fi Sunlogger Ingo's Wi-Fi Sunlogger is a solar-powered data collector that records sunlight exposure. This RCM3400-based device is the perfect tool to have on hand when scouting out sites for solar panel installation. Download: Cyliax172.zip
30 Daniel Ramirez	Math Coprocessor for Robotics Applications Need more processing horsepower for your robot? This design provides additional functionality to microcontrollers that don't support floating-point math and to those that are too bogged down with other functions. Download: Ramirez172.zip
38 Enoch Hwang	Build a VGA Monitor Controller Enoch built a VGA monitor controller with just two 10-bit binary up counters, four SR flip-flops, and 11 AND gates. The result is an impressive solution for displays. Download: Hwang172.zip
44 Eddie Insam	Interface Ethernet and Embedded Systems Fast Ethernet and small microcontrollers do not mix, or so they say. In this article, Eddie shows you how to add full-speed, 100-Mbps Ethernet to an embedded system. Read on to learn about the supporting hardware that will help you get the job done.
Applied PCs 54 Fred Eady	HTML TCP/IP Stack Solution A Detailed Look at the CMX-MicroNet If you need more than a minimal TCP/IP stack for your next application, consider using the CMX-MicroNet, which is a stack designed for microcontrollers that have small amounts of data and program memory. This month, Fred describes the CMX-MicroNet's behavior. Download: Eady172.zip
62 Jan Axelson	Network Security for Small Systems Nervous that someone might tamper with your embedded system? It's a common concern, but not too many designers have the know-how to secure a small system. In this article, Jan walks you through the process of protecting a system's code and data.

From the Bench 70 Jeff Bachiochi	USB DMX Several months ago, Jeff interfaced a DMX receiver to a water fountain system. He used a commercial serial DMX converter for that project. This month, he describes how he updated the device with a C8051F320-based USB interface. Download: Bachiochi172.zip
Silicon Update 78 Tom Cantrell	Easy to Be Soft Although FPGA-based processors won't ever completely replace dedicated processor chips, the FPGA soft-core option is becoming increasingly attractive to designers. In this column, Tom examines the soft core concept by focusing on Altera's new chips and the Nios II core.
