CIRCUIT CELLAR

INTRODUCTION
When any good engineer worth his solder finishes a long-term project,
he immediately begins assessing what he accomplished in an effort to
prepare for future endeavors. We like to do the same thing. So, after finishing
this issue, we reviewed our 2008 editorial endeavor—publishing 12
fresh issues of Circuit Cellar—for the purpose of noting our accomplishments
and planning what is to come.
In late 2007, we set five major goals for 2008. We achieved them all.
The way I see it, we put a lot in and you got a lot out. Let’s review.
1. We planned to highlight Circuit Cellar’s 20th anniversary. We did so by
publishing Ed Nisley’s retrospective article, “That Was Then, This Is Now” (Issue
210), and introducing a new front cover layout. We also reinstated an old fan
favorite, the EQ section. Many thanks to Dave Tweed!
2. We set out to incorporate articles from the most diverse set of engineers
to date. We achieved this by running stellar articles by talented engineers
from such distant places as Dallas, Texas (Ben Smith, Issue 210),
Bogota, Colombia (Diego Mendez Chaves, et al, Issue 211), Tokyo, Japan
(Yoshiyasu Takefuji, Issue 213), Gorizia, Italy (Carlo Tauraso, Issue 216), North
Olmsted, Ohio (James Blackwell, Issue 218), and Pune, India (Mandar Bagul,
Issue 221).
3.We aimed to publish useful articles about renewable energy resources.
This year, we ran five articles on the subject in the Intelligent Energy Solutions
section of the magazine.We hope to continue publishing such articles in 2009, but
we need your help. It’s up to you to start planning the next batch of articles about
energy-efficient applications.
4.We promised to continue running useful graphics-related articles even
though we were removing the Graphics & Video issue from the editorial
calendar. We came through by publishing several graphics-related articles.
James Blackwell’s article titled “Content Collection and Display” (Issue 218) is
an excellent example.
5.We resolved to challenge readers to work on articles about programmable
logic-related topics. This month, we deliver an article by Kareem Matariyeh
about the Verilog language and programming FPGAs and CPLDs (p. 78).
To make this issue memorable, we packed it with articles about realworld
applications and handy new design tools. Starting on page 14, John
Peterson describes an expandable platform for light and animation. Design,
program, and rearrange! Turn to page 24 for Tom Cantrell’s useful introduction
to Altium’s Designer and Nanoboard.To learn about another handy
tool, check out Jeff Bachiochi’s article “Component Control” (p. 62). On
page 32, Mandar Bagul begins an article about an affordable mobile data
storage solution. On page 38, Ed Nisley covers the topics of NiMH charging
and designing a three-pack charger. If you want to build an electronic
identification system, check out Jan Szymanski’s description of his MCUbased
badge project (p. 44). Robert Lacoste demystifies the topic of proportional
integral derivative (PID) control on page 54. On page 69, Martin
Courtney introduces two beamforming techniques: adaptive and fixed.
We will run dozens of thought-provoking articles in 2009.You can e-mail
me an article proposal or submission at any time
