About Circuit Exchange
Circuit Exchange is my personal, non-profit home page. First started in March 1999, my site contains a database
of all new schematics, not borrowed from other sites. I have since added sections on analysis and circuit design and
simulation. Circuit Exchange (CXI) is open to everyone and I welcome contributions or just feel free to
browse the site. The original site was started with Freeserve (now Wanadoo) and I still maintain the
original freeserve site but only update this site two or three times
a year. However since moving to broadband, I changed ISP's and the main site is now hosted by
Zen Internet. The home page is translated into 10 languages and I am most grateful to the following people who
have made this possible :-
Amanda Van Leeuwen, Ricardo Venegas, Sindhu Adi Wijaya, Paulo Roberto do Amaral, Maria Rosendahl,
Marco Deferre, Fidel from Ukraine, Hartmut Schneider
All contributers appear on my scrolling credits page. For best browsing results,
I recommend setting your display to at least 1024 x 768 pixels.
Please read before emailing. Very Important!

my previous email restrictions have been removed. However before asking for help, please take a look in
the Practical section to see if your question is answered.

How this site is made.
My computer is a multi boot system running 8 different versions of linux and windows. Originally, I worked
extensively with the German distribution Suse, but now have moved to
Gentoo Linux. All linux software can
be run on any distribution and I use the following packages :-
All graphics and backgrounds are made with the Gimp. This is also available for Windows now as well. The web site is wrote with Quanta Plus. My HTML is hand written so I hope will be compatible with any web browser. Most schematics are drawn with Circuit Maker and
Tina although I have recently started using Xfig. Diagrams and
pinouts are created using Sun Microsystems Open Office.Org. Open Office is free to download, has been translated into many different languages and is available for FreeBSD, Linux, Mactintosh, Solaris and Windows.
Frequently Asked Questions
i) Most components are labeled using the System International numbering system.
ii) Please don't ask for schematics for domestic electrical or electronic equipment, I don't have any.
iii) This site is non-commercial, I do not sell or buy, components or circuits on this site.
iv) The update page contains links to the newest pages on my site.
v) I regret that I cannot help with college/school/university/project work, but see the section
below.
Help with Project Work
I get many requests for help with home work, college work, university work, diploma work.
Sorry but I do not have the time to answer these questions. You may be able to get some
help on the following newsgroups but before seeking help, you must try and work things out
for yourself. If you copy other peoples work then you will only be cheating yourself.

Newsletter
I am currently trying a new newsletter by Domeus. After entering a valid email address and pressing
send, you will receive an email from Domeus. Click to accept the invitation, you do not need
to do anything else, the password Domeus offers you is for services on their site only.
In a few days I will send out a test message and a site update is due out next week.
About the Web Master
My interest in electronics started when I was about 7, from listening to my parents old radiogram. I was always fascinated tuning the radio on medium wave to hear what new stations could be heard. Many languages and different countries at night were possible. Today, the wavebandsare much more crowded and there is much more artificial interference on medium wave, so the hobby now is much more of a challenge. The same year I went to the library and got books on radio and electronics. I built my first crystal set and it was amazing to pick up the local and regional stations at that time. As time went on, I progressed to more complex receiver circuits and then onto alarm and relay circuits. Over the years, electronics still remained one of my passionate hobbies. Even if I did not construct anything, I would always have magazines or electronic books from the library to read. I have always enjoyed experimenting and building circuits.
Electronics can be very rewarding and sometimes challenging. It is always good to hear from fellow hobbyists
around the world. I would recommend reading "The Art of Electronics" by Harrowitz and Hill, and if you are interested in computer simulation,"The Spice Book" by Andrei Vladimerescu is a good choice.
Other hobbies include short wave listening, music, and computers. I became interested in Linux in about 1999 and now run many operating systems on one hard drive. Currently I run Suse, Debian, Ubuntu, Slackware, PCLinuxOS, PCBSD, Solaris 10, and Windows. Of course you can only use one system at a time, but by multibooting I have the best of all worlds.
