Optical
Proximity Sensor for Robots (Part 2):Open-Source
PCB Layout Editor
Stuart
Brorson
Last
month Stuart piqued your interest in his PCB-based
optical proximity sensor. Now he explains how to
lay out the proximity sensor using the gEDA suite’s
layout program. You’re only a step away from being
able to design PCBs with the open-source gEDA suite!

Stock
Clock: Wireless Network Delivers Market Data
Richard
Hoptroff
Using
the basic idea behind a wireless weather station,
Richard built an Internet-enabled, stock monitoring
system. But don’t worry if monitoring the stock
market isn’t your thing. You can use this easy-to-build
ZigBee-based system to pull virtually any other
kind of textual information off the ’Net and display
it on your dial. p. 58
