Discover how to make a miniature electric duster using simple components like an electric motor, battery, toggle switch, ...

Passive components – resistors, capacitors, inductors, and connectors – usually don’t get a lot of consideration until late in the design, but they are vital elements of a functioning circuit, ...

[Lucid Science] shows us how to make some simple reed switches. Reed switches are simple components that detect a magnetic field and can close or open a circuit once detected. While not really a thing ...

The science experimenters at TKOR show how to build an eye-catching glowing water fountain that looks almost magical using simple components. Senate’s likely next No. 2 warns Trump if Democrats take ...

A few simple components are all it takes to create an over-temperature alarm. The circuit in Figure 1 requires only an ordinary negative-temperature-coefficient (NTC) thermistor, two common ICs, and a ...

I get somewhat annoyed when I hear engineers who have some real-world experience or exposure casually dismiss a component, especially a passive one, as “simple.” It may be simple in concept or ...

Despite the availability of FPGAs and microcontrollers, the historical use of analog circuitry to implement some arithmetic functions is still a viable and cost-effective technique. For the division ...
