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 ...

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 induced in the spring which is sufficient ...

After nearly a decade and five major nodes, along with a slew of half-nodes, the semiconductor manufacturing industry will begin transitioning from finFETs to gate-all-around stacked nanosheet ...

In this lesson, students search for transistor-based devices at school. They use the results of their search to explain the significance of the transistor in their lives. A transistor is a tiny ...

In my chart recorders the modulating and demodulating was performed by the 50 Hz reed switch, and the germanium transistor AC amplifier was able to do a good job of working with the resulting 50 ...

“AC was as per specifications. Works well even in low temperatures like 28 degrees. Energy efficient. For a room space of 180 sq ft, it cools well even at temperatures set at 28 degrees with ...
