Acknowledgements

First, I wish to thank my wife, whose patience during those many and long evenings (and weekends!) of typing has been extraordinary.



I also wish to thank those whose open-source software development efforts have made this endeavor all the more affordable and pleasurable. The following is a list of various free computer software used to make this book, and the respective programmers:


  • GNU/Linux Operating System -- Linus Torvalds, Richard Stallman, and a host of others too numerous to mention.
  • Vim text editor -- Bram Moolenaar and others.
  • Xcircuit drafting program -- Tim Edwards.
  • SPICE circuit simulation program -- too many contributors to mention.
  • Nutmeg post-processor program for SPICE -- Wayne Christopher.
  • TEX text processing system -- Donald Knuth and others.
  • Texinfo document formatting system -- Free Software Foundation.
  • LATEX document formatting system -- Leslie Lamport and others.
  • Gimp image manipulation program -- too many contributors to mention.
  • Winscope signal analysis software -- Dr. Constantin Zeldovich. (Free for personal and academic use.)

Appreciation is also extended to Robert L. Boylestad, whose first edition of Introductory Circuit Analysis taught me more about electric circuits than any other book. Other important texts in my electronics studies include the 1939 edition of The “Radio” Handbook, Bernard Grob's second edition of Introduction to Electronics I, and Forrest Mims' original Engineer's Notebook.



Thanks to the staff of the Bellingham Antique Radio Museum, who were generous enough to let me terrorize their establishment with my camera and flash unit. Similar thanks to Jim Swartos and KARI radio in Blaine, Washington for a very informative tour of their expanded (50 kW) facilities as well as their vintage transmitter equipment.



I wish to specifically thank Jeffrey Elkner and all those at Yorktown High School for being willing to host my book as part of their Open Book Project, and to make the first effort in contributing to its form and content. Thanks also to David Sweet (website: [*]) and Ben Crowell (website: [*]) for providing encouragement, constructive criticism, and a wider audience for the online version of this book.



Thanks to Michael Stutz for drafting his Design Science License, and to Richard Stallman for pioneering the concept of copyleft.

Last but certainly not least, many thanks to my parents and those teachers of mine who saw in me a desire to learn about electricity, and who kindled that flame into a passion for discovery and intellectual adventure. I honor you by helping others as you have helped me.
