What makes it rather special is that it relies on only one type of device, every one of its transistors is a BC547. In design terms, it follows the lead set by other simple amateur transmitters ...

The circuit is a simple one, and a classic. The spring from a ballpoint pen is soldered to the base of a BC547 transistor, and when held close enough to a conductor carrying AC power, a current is ...

The first transistor was about half an inch high. That's mammoth by today's standards, when 7 million transistors can fit on a single computer chip. It was nevertheless an amazing piece of technology.

In the beginning, there was the point-contact transistor. This was the very first transistor ever made, built by Walter Brattain with the help of John Bardeen. It was made of two gold foil ...

If you have an interest in electronics and have been hanging around DIY tech forums for a while now, chances are you already ...

CMOS technology combines two types of transistors that work together, leading to efficient power use and high noise immunity. CMOS technology uses two different types of transistors, n-type (nMOS) and ...

Transistors are small, versatile semiconductor devices designed to switch or amplify electronic signals and power. Almost all electronic devices today contain one or more transistors. Some transistors ...

The electronic transistor and the logic gates based on it have qualitative features that are crucial for systems of any complexity, but very few optical transistors or logic devices possess them 3.

After an exhaustive review of suspect transistors in NASA's Europa Clipper spacecraft, NASA managers have cleared the probe for launch next month as planned on a $5.2 billion mission to find out ...

This category includes photodarlingtons. While ordinary transistors have photosensitive effects when exposed to light, phototransistors are optimized for use with light. Phototransistors have larger ...
