April 1963 Popular Electronics Cover - RF Cafe  Table of Contents

People old and young enjoy waxing nostalgic about and learning some of the history of early electronics. Popular Electronics was published from October 1954 through April 1985. All copyrights are hereby acknowledged. See all articles from Popular Electronics.

This quiz from Popular Electronics challenges (not too much, though) your knowledge of energy conversion in common devices. A few of them might be unfamiliar to people born after about 1990, but even so, you've probably seem them all at some point, especially if you are a regular RF Cafe visitor (meaning you're probably smart). Robert P. Balin constructed many of this type quiz for PE. In fact, clicking on the following hyperlink will find the Popular Electronics Quizzes for you.
