All I require is a plain vanilla text file (your-file.txt) of your written copy and, gif or jpg files of your schematics and photographs. Don't worry if you think your writing isn't terribly brilliant, that's what I'm for. Most times I need to edit work either for space, clarity or simply making it search engine friendly.

ARE YOU REALLY SERIOUS ABOUT LEARNING ELECTRONICS?

If you seriously want to learn about electronics then the first thing I sincerely recommend you do is buy yourself this excellent reference book (below) through my Amazon affiliate program. This will continue to prove a good initial investment in your ongoing education. As you can see it has comprehensive topics and is very modestly priced for a publication of its calibre. Other recommended titles appear to the left.

RF CIRCUIT DESIGN

- Chris Bowick, WD4C

I have never read a better book on RF design. Chris's book is a constant reference for the serious RF designer. You will be amazed at the quality and the quantity of the content. As someone commented, "This is THE book to learn how to use a Smith Chart" - 176 pages

ONE OF A NUMBER OF UNSOLICITED TESTIMONIALS

Hi Ian,

Just a quick note to say thanks for the book-shop department. I took your advice and bought the book by Chris Bowick. It's great. The material is very well presented and it is just right for about every level from beginner to engineer. Good choice!

Regards,

Larry L. Beavers CPBE W1GTA, Assistant Chief Engineer, WBZ Newsradio 1030

ELECTRONICS QUESTIONS AND ANSWERS

If you are involved in electronics then consider joining our "Electronics Questions and Answers" news group to share your thorny questions and answers and help out your colleagues.

The absolute fastest way to get your questions answered and yes, I DO read the posts.

This is a mutual help group with a very professional air about it. I've learn't things. Not for absolute newcomers to ask very basic questions already covered by these tutorials BUT it is an excellent learning resource for lurkers.

Presently [September, 2010], there are now over 1,100+ subscribers and it's FREE! Join our "Electronics Questions and Answers" news and discussion group NOW!

ANTENNAS

This section is completely new. The first instalment on antennas is about the basics of antennas including quarter wave verticals, half wave dipoles, folded dipoles and collinear arrays. Much more will be added over time.

BASIC ELECTRONICS TUTORIALS

Starting out you need to cover basic electronicswhich encompasses the topics of ohms law, voltage, current, resistance, capacitance, inductance, reactance, impedance and Q. Further topics in these basic electronics tutorials are power supply basics as well as digital basics.

EARTH DANGERS

In particular I would commend everyone to read my page on earth dangers. It could possibly save your life or the life of a loved one.

I think it ought to be compulsory reading for everyone.

AMPLIFIER DESIGN, HAM RADIO

Major electronics tutorials range from amplifier design, general radio design to amateur radio or as some prefer, ham radio.

LC FILTERS

A huge LC filter design section includes bandpass filters, low pass filters and high pass filters as well as narrow band pass filters. I've even started on active filters with a page on Active band pass filters.

RECEIVERS, OSCILLATORS, TRANSMITTERS

Further electronics tutorials are on receiver designincluding am receivers, fm receivers and general coverage receivers which incorporate ssb as well as cw. Transmitter design covers oscillators including crystal oscillators, voltage controlled oscillators, hartley and colpitts oscillators. Frequency drift in oscillators is discussed along with oscillator drift correction circuits. These are followed by amplifier topics on buffer amplifiers, low level rf amplifiers as well as linear amplifiers.

TEST EQUIPMENT

In the test equipment section so far I've discussed meters, meter shunts and NOW a fantastic Spectrum Analyzer Project for you to construct and own at relatively low cost. Don't miss it!

DATA SHEETS

Progressively I'm gathering links to the more popular data sheets in PDF format. These include the MC3362 single channel VHF FM narrowband receiver, 555 timer, NE602 mixer, 2N2222A bipolar transistor, MPF102 J-FET and more.

I've included a short summary and links to data sheets for the popular MC12149 Low power voltage controlled oscillator buffer which is intended for applications requiring high frequency signal generation up to 1300 MHz.

Also included is the MC12181 125 – 1000 Mhz Frequency Synthesizer. The MC12181 is a monolithic bipolar synthesizer integrating a high performance prescaler, programmable divider, phase/frequency detector, charge pump, and reference oscillator/buffer functions.

FREE DOWNLOADS, AND A SITE MAP

For convenience www.electronics-tutorials.com have provided you with a site tree of all the electronics tutorials offered on this site. It is highly recommended you begin with the basic electronics tutorials.

I have also included a valuable FREE downloads section of software likely to assist you in pursuit of your interests in electronics. Tell your friends about this page!

I'm often asked about the reference and text books I'd recommend. Here are a few real quality titles I can really recommend with absolute confidence, all written by highly respected authors. Please note I have an affiliate program with Amazon Books which assists toward site costs.

In recent months, McGraw-Hill Professional Publishing have been sending me a number of interesting titles to review personally, that's confidence!. I will of course present these book reviews as time permits.
