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 ...

Transistors, the tiny switches that flip on and off inside computer chips, have long been the domain of electricity. But scientists are beginning to develop chip components that run on light. Last ...

A load switch is an electronic switch. It works like a relay to power supply rails in systems, but it has no moving parts. Load switches are increasingly found in today’s portable electronic devices, ...

On a physical level, a transistor’s internal functioning is very complex, but, in practice, using it in some simple experiments is quite easy and affordable for everyone. A transistor allows to create ...
