Inductors are not the most common component these days and variable ones seem even less common. However, with a ferrite rod and some 3D printing, [drjaynes] shows how to make your own variable ...

Amateur Radio as a hobby has a long history of encouraging experimentation using whatever one might have on hand. When [Tom Essenpreis] wanted to use his 14 MHz antenna outside of its designed ...

When choosing a conductor for use in an electronic circuit, there are several important properties that may need to be considered. The wire thickness and resistivity determines the current carrying ...

Inductors, coils and chokes are passive devices that are designed to resist changes in current and store energy in the form of a magnetic field. In their simplest form, inductors consist of a wire ...

Discover the latest articles and news in related subjects. In this paper, we implement a fabrication process of Si-embedded 3D air-core inductors for VHF power conversion applications. The inductors ...

“Drum core” is used to describe the shape of the ferrite core used in some power inductors, and it differentiates these inductors from other types such as toroidal, power bead, flat coil, or planar.
