Thermocouples and their leads often have to detect open-circuit or short-circuit faults. However, it is very difficult to distinguish a valid millivolt temperature signal from an open/short-circuited ...

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 ...

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 ...

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 . . .

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 ...

Replay: Transistors are, literally, a miracle. Phil Rhodes recently looked at how they work. Now, let's see where they're going to take us. I feel I have a special connection with technology. It might ...
