This two transistor AM radio circuit is also called “mini-radio”. It uses only 2 transistors and few passive components which makes is very easy to be constructed. Although the circuit is very simple, ...

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 ...

When we build an electronic project in 2016, the chances are that the active components will be integrated circuits containing an extremely large amount of functionality in a small space. Where once ...

When one thinks of the most significant dates in our technological development, October 18, 1954 doesn't pop up there at the top of the list. It should; 60 years ago the first portable transistor ...

As World War II gripped Europe, Winston Churchill knew that the conflict would be fought on two fronts—on the battlefield and in the scientific lab. The race between the Allies and the Axis powers to ...

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 ...

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 ...
