With just three transistors, one relay, and some resistors and capacitors, a single light switch can provide sophisticated control of high-power and low-power lamps. With just three transistors, one ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

We like to pretend that our circuit elements are perfect because, honestly, it makes life easier and it often doesn’t matter much in practice. For a normal design, the fact that a foot of wire has a ...

OK, so I have an old project laptop with an IDE/PATA/slim-ATAPI optical drive bay, into which I have inserted a SATA drive caddy with a bridge board. The thing is, the caddy doesn't transfer the drive ...

CHAMPAIGN, Ill. -- Engineers are unveiling an upgrade to the transistor laser that could be used to boost computer processor speeds - the formation of two stable energy states and the ability to ...

Transistors are tiny electronic components that act as switches and amplifiers, and they dwell at the heart of modern technology. In simple terms, a transistor can turn a flow of electricity on or off ...
