by Brad
Zdanivsky
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. p. 12
Keywords:
Telemetry, web,
browser, Java, cellular modem, XML, TStik
TINI400, altimeter, pressure, TAI8570, GPS,

Long-Range
Wi-Fi Network
Nick
Dargahi
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. p. 20
Keywords:
Wi-Fi, WAP, distance, 802.11, high-gain antenna,
parabolic, waveguide, focus, Shannon's law, Netstumbler

Downlink
Telemetry Module
Leonid
Shvarzberg
Freescale Wireless Design Challenge Winner
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. p. 32

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. p. 40

Unlock
the Power of the PCI Bus
Alexandre
Desnoyers
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
µCLinux to the SDRAM chip on the PCI board and then
boot a Microblaze system implemented in the same
FPGA. p. 44

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. p. 52

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. p. 56

Portable Color Organ
Jeff Bachiochi
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.
