Thank you for visiting Electronics Notes. On the site I aim to provide accessible summaries, and information with a minimum of jargon covering many electronics engineering topics. All the topics are manually written by myself and the aim is to provide useful information that is easy to understand and to include many hints, tips & practical guidance notes using my experience from my many years as an electronics engineer.
Electronics Notes is written and run by Ian Poole

Technology history
Discover some of the stories that detail how the foundations were set in place for today's technology.
We have a large number of pages devoted to pioneers, how technology was invented and developed as well as descriptions of many types of radio receiver, etc, etc.
How the Transistor was Invented
The transistor is arguably one of the most significant inventions of the 20th century - find out how it was invented and by whom.
Electronics Notes aims to provide accessible summaries about a host of electronics, radio and connectivity technologies in a practical and useful way.
Our aim is to support those who want to learn about the technology: those who are established engineers as well as students and hobbyists.
The topics included in the site range from the basic electronics concepts (useful for established engineers as well looking for those equations, formulas etc, including topics like basic electronics concepts, component descriptions and explanations, circuit designs and circuit design principals, manufacturing techniques, radio technology & RF design and wired and wireless connectivity and a host of other topics.
To fund the running of the site, we obviously need to carry advertising, but we aim to make this not too intrusive. We hope you understand, but we need to have income to meet the not inconsiderable running costs.
