Ernie Baum of Hasbrouck Heights was 13 years old when tragedy struck. “I went with my family to visit my father’s aunt in Manhattan, and someone broke into our car and stole my transistor radio,” he ...

And now a page from our "Sunday Morning" Almanac: October 18th, 1954, 61 years ago today ... the day Dick Tracy's wristwatch radio came its closest yet to reality. For that was the day Texas ...

So What Was the Transistor Good For? Transistors may have been useful to the phone company and to a handful of scientists building computers, but that wasn't enough to build an industry. Companies ...

Carbon nanotubes have a sound future in the electronics industry, say researchers who built the world's first all-nanotube transistor radios to prove it. The nanotube radios, in which nanotube devices ...

Individual words are basic communication tools that when put together in the proper order can express thoughts and ideas. When you put certain words together, they can be magical. Back in the 1960s, ...

Two years ago was the 50th anniversary of the 1964 British Invasion spearheaded by the Beatles, and 1965 marked the rise of the Rolling Stones and Motown, among other notables. Both summers featured ...

Transistors have come a long way. Like everything else electronic, they’ve become both better and cheaper. According to a recent IEEE article, a transistor cost about $8 in today’s money back in the ...

How did most people hear radio news reports in the 1920s-1940s? Families sat in their living rooms and listened to very large receivers. But on December 16, 1947, three scientists helped develop the ...

If you cultivate an interest in building radios it’s likely that you’ll at some point make a simple receiver. Perhaps a regenerative receiver, or maybe a direct conversion design, it’ll take a couple ...

CHAMPAIGN, Ill. — Carbon nanotubes have a sound future in the electronics industry, say researchers who built the world’s first all-nanotube transistor radios to prove it. The nanotube radios, in ...

The schematic diagram shows an audio stage with a common-collector circuit. This does not damp the tuned circuit, but instead actually increases its response. This yields good sensitivity and ...

Here is a simple circuit for a one transistor Audion type radio powered by a 1.5 V battery. It employs a set of standard low-impedance headphones with the headphone socket wired so that the two sides ...
