Thank you for visiting Electronics Notes. I'm aiming to make this a quality resource hub or resource centre for electronics engineers at all levels from hobbyists to professionals. With the website, videos, social media and my online shop, I aim to provide accessible resources and information for free or for a low cost (the site and everything else have some significant running costs).
Electronics Notes is written and run by Ian Poole
The Electronics Notes online shop offers not only our own downloadables and coffee mugs, etc, but also a huge number of electronics products from our selected suppliers. Check it out now!

My YouTube Channel: What's Happening
In a forthcoming video, I'll be looking at trap that is easy to fall into with SMT ceramic capacitors (MLCC) sizes - watch out for that video this coming Friday.
In another video I'm just finishing off, I take a look at the Xiegu VK6 iambic Morse key.
I'm also preparing videos on topics including SWR / VSWR, gold conductivity and a few other ideas. And I am finishing off my 2N30055 video.
There are plenty more exciting ideas in the melting pot that will be coming soon, so keep checking out my YouTube channel.

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.
Racal RA17 Communications Receiver
The Racal RA17 was a high performance communications receiver introduced in 1955 and it boasted unparalleled frequency stability as a result of the use of the famous Wadley Loop.
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.
