4 Jennifer Huber	HTML Task Manager Finding Inspiration
8 John Gorsky	New Product News MAX4901-05 single-supply analog switches from Maxim Integrated Products, Inc. OrbiTrak PC/104 GSM modem with GPS from Parvus Corp. LT3486 dual step-up converter for white LEDs from Linear Technology Corp. Half-InchModem for voice, fax and data from Radicom Research, Inc.
12 Brad Zdanivsky	Browser-Based Telemetry System Brad used Java to create an Internet browser-based telemetry system for his rock climbing expeditions. In addition to generating an Internet feed, the inexpensive system collects heart rate, blood pressure, and temperature data. Download: Zdanivsky_185.zip
20 Nick Dargahi	Long-Range Wi-Fi Network Last spring, Nick and a team of electrical engineering students created a 1.23-mile Wi-Fi link across San Francisco's Lake Merced. In this article, he shows you how to build a similar network without breaking the bank.

32 Leonid Shvarzberg	Downlink Telemetry Module Leonid recently built a downlink telemetry module for his RC helicopter. The on-board system collects status information about the helicopter and transmits it via a wireless ZigBee link to a laptop. The system is built around an MC1392 SARD board.

40 Steve Hageman	LAN-Based Data Acquisition System Steve built his LanDas LAN-based data acquisition system as a replacement for his old serial-based design. It enables him to reuse code and software to acquire data with his PC. Download: Hageman_185.zip
44 Alexandre Desnoyers	Unlock the Power of the PCI Bus The PCI bus is a major part of every PC. Alexandre shows you how to unlock the PCI bus's power for your next project. His next project is a system to upload uCLinux to the SDRAM chip on the PCI board and then boot a Microblaze system implemented in the same FPGA. Download: Desnoyers_185.zip
Above the Ground Plane 52 Ed Nisley	ADC and DAC Bandwidth Sampled Signals ADC bandwidth. What really happens when the analog input frequency exceeds the ADC's ability to handle it? Everybody talks about Nyquist, but what does it look like in the real world? Ed shows you with a low-frequency, sampled-data circuit. Download: Nisley_185.zip
Applied PCs 56 Fred Eady	Assume Control with the MC104P Fred was blown away when he saw Calmotion's MC104P PC/104 form factor controller in action at the July Microchip MASTERs Conference in Arizona. After introducing you to the MC104P, he explains how you can bring PC/104 functionality to your next project.
62 Ken Chapman	Solar Panel Monitor Ken built a multiprocessor system to monitor the solar panels on his house. You can use his fully programmable system to monitor and record numerous forms of technology. Download: Chapman_185.zip
From the Bench 72 Jeff Bachiochi	Portable Color Organ A color organ is an electronic circuit that uses audio signals to control the brightness of lights. The stronger the audio signal, the brighter the lights. Jeff recently used an LM4970 audio synchronized color LED drive in a portable color organ design. Download: Bachiochi-185.zip Bachiochi_185.zip
Silicon Update 78 Tom Cantrell	Get the LEDs Out Interested in adding an LED lightshow to your next design? Tom's got the perfect part for you. This month he illuminates Dialog Semiconductor's DA9026 universal LED controller and lightshow generator. Let there be light!
