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, ...

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 ...

This circuit is essentially an amplified crystal set. The inductor could be a standard AM radio ferrite rod antenna while the tuning capacitor is a variable plastic dielectric gang, intended for small ...

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 ...

Baldwinsville, NY -- In 1953, the cutting edge of technology was the transistor, and General Electric’s plant in Salina was where theory was being turned into reality. A team of engineers led by ...

A very simple but highly efficient combination lock circuit is shown in the figure. Any type of on/off switches can be used, varying from commercially available inexpensive types to more sophisticated ...

OCTOBER 18, 1954: Transistor radios hit the shelves on this day in 1954 – and went on to sell billions and become the most popular electronic communication device in history. Texas Instruments’ ...

THE properties of the amplifier to be described are entirely due to the type of transistor used, and the purpose of this communication is to report on its suitability for the amplification of ...
