An
RF Lap-Scoring System—by Pete Cross
Trying to determine which mud-covered vehicle is
the first across the finish line can be a messy
task. If you can’t buy a scoring unit, it’s
time to find a better solution. Pete considered
a variety of technologies to keep the information
flowing. In the end, RF came out on top. pg 10

Part 2: How The Brain Works—by Daniel Ramirez
Like many electronics enthusiasts, Daniel cut his
teeth on a Heathkit project. Building the Hero I
was a learning experience the first time around,
now he’s going back to upgrade the robot and
update the hardware. With his board, some IR sensors,
and a PIC, he limits the intrusion. pg.20

—Jerry Wasinger
Whether mother nature sends you running
for the root cellar regularly or you just
like knowing what’s happening in your
backyard, Jerry’s weather station can
help. With a PIC micro, sensors for temperature,
humidity, and pressure, and a VB program,
you’re all set. pg.34

Measuring
RF Field Strength—by SE Nickols
With RF techniques being used in more and more embedded
products, often developers need to be able to measure
RF field strength. With less than $100 in the budget,
building your own direct decibel-reading device
just might be the best way to monitor the situation.

Keywords:
RF, field strength, path loss, log amp, AD8307,
antenna, gain, frequency

PICing a Place on the LAN—by Fred Eady
The buzz is that Ethernet capability is creeping
into everything. If you’ve tried to join the
trend but hit a wall when trying to collect the
necessary documentation, you’re not alone.
Equally frustrated, Fred trekked across the ’Net
to dig up what you need, and compiled a guide book.

Choosing IR Technology—Bruce Reynolds
When looking for a wireless communication solution,
the IR route can be your best bet. However, you’re
challenged to make sure your device meets the current
requirements and restrictions. As Bruce shows us,
finding the right IR solutions is well worth the
effort. pg.58

IR, wireless, communications, detectors,
PNA4613M, settling time, burst length, carrier frequency,
spectral sensitivity, band-pass frequency, PWM,
peak pulse current, power control, AGC, EMI, LED

Probe This—by Jeff Bachiochi
Jeff
learned to make do without an oscilloscope. But
when he saw an affordable, pen-type ’scope,
the offer was too good to pass up. With his new
osziFOX, he went to troubleshoot circuits.

UPDATE
The Last Micro?—by Tom Cantrell
Back when rumors of doom for 8-bit micros were rampant,
Tom held his tongue and waited to see what would
really happen. After looking at an offering from
Xemics, he noticed enough new perks to defy the
rumors. pg.74
