We always stress how efficient electric cars are. It is important to have that in mind, and Jason Fenske recently reminded us of that with a video about the huge impact tires can have on EVs. Texas ...

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 ...

One secret to creating the world's fastest silicon-based flexible transistors: a very, very tiny knife. Engineers have now pioneered a unique method that could allow manufacturers to easily and ...

Hacker [Dino Segovis] is back with yet another installment of his Hack a Week series, and it’s looking like he isn’t too worse for wear after hunkering down to face hurricane Irene. This week, it ...

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 ...

The transistor is the tiny invention that powers the modern world - but its creation was anything but simple. This video explores how a small group of engineers overcame impossible challenges to ...

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 ...

The Ambilight system – built in to high-end Phillips TVs – is a neat system to add a bit of ambiance to regular television viewing. With this system, a series of RGB LEDs are mounted to the rear of ...

THE properties of the amplifier to be described are entirely due to the type of transistor used, and the purpose of this communication is to report on its suitability for the amplification of ...
