Events, Advances, and News
Read about a transistor that learns, secure wireless
access, the Smellophone, plus some other cool stuff.
12 The Spin Zone
Adventures in Propeller Programming
Sometimes the simple tried-and-true solutions are
overlooked because of the ever-increasing
sophistication of microcontrollers.
Case in point: shift registers.
Reader Questions Answered Here
Questions on LED drivers, remote control, and video
and power over cable are answered.
52 Smiley’s Workshop
Programming • Hardware • Projects
The Arduino Classroom.
Even though the Internet is flowing with tutorials on
how to use the Arduino microcontroller, sometimes
it’s nice to have everything put together into an
easy-to-follow introductory course. That’s what
we’ve done here.
62 Near Space
Approaching the Final Frontier
A New Airframe Design for
Near Spacecraft — Part 2.
Building a new airframe is only part of creating a
near spacecraft. There are things like post burst
chaos that have to be considered.
67 The Design Cycle
Advanced Techniques for
Utilizing Embedded Web Development.
Remember drilling that slightly off-center toggle
switch mounting hole for your project's front panel
then have it be a bit too large? Those days are long
gone. Trade in that drill and dull set of metal bits for
some silicon versions that machine a perfect virtual
front panel every time.
28 Build a PIC-Based Remote
You can never have too many remote sensors,
right? This circuit lets you set up a homemade
weather station to monitor the most popular
of all parameters: temperature.

34 The (Nearly) Universal Process Monitor
While the circuit described here is specifically for
showing system parameters in an electric truck
conversion, you can utilize it as a process monitor
and display for analog and pulsed signals in a
variety of applications.
■ By Daniel Gravatt
38 All About Clocks for PICs
Taking the time to understand how clock options
really work in a microcontroller will make
implementing them that much easier.
■ By Thomas Henry
44 MakerPlot — The DIY Software Kit
Learn how to plot both analog and digital data from
the Arduino Uno, then see how to log that data and
play it back for greater analysis.
