A variety of new and used vintage and hard to find radio components for home brew projects including:

I make no claims for technical accuracy, good design, or necessarily even originality for the contents of these pages. Rather, I am a simple enthusiast attempting to convey my love and enjoyment of radio, electronics, and computing and perhaps to inspire YOU to build something too. The following pages document projects that I have built over a period of 30 years. Wherever applicable I have named sources and references.

Radio Hobbyist’s Designbook or RHdb (for short) was designed to guide you into design of
electronics apparatus that relates to radio. It assumes you know something about electronics
but you can skip Chapters which cover familiar subjects. Mathematics needed in design is down
to simple algebra and trigonometry. Topics cover the frequency spectrum of DC through VHF.

You must supply the brainpower. But RHdb can be your main reference, a guidance toreaching
your personal hobby goal. RHdb is written in a sort of Reader’s Digest format: Short and
to-the-point, covering things simply with a minimum of words. Grouping is in 5 sections as
givenbelow with a synopsis of Chapters

We are gathering information on interfaces of modern and obsolete electronic hardware: pin-outs of interface ports, diagrams of PC components, wiring of various devices and connectors. Information on functions of pins in connectors (pinout) is essential for everyone who wants to explore modern hardware, investigate the way it works, interconnect various devices, make DIY electronic equipment.

There are 3134 documents in our database.

These notebooks sold at Radio Shack when I was growing up in the mid 70s and 80s were very popular and great education source. From the Wikimedia article: "Forrest M. Mims III is an American amateur scientist, magazine columnist, and author of Getting Started in Electronics and Engineer's Mini-Notebook series of instructional books that were originally sold in Radio Shack electronics stores. Mims graduated from Texas A&M University in 1966 with a major in government and minors in English and history. He became a commissioned officer in the United States Air Force."
