The most difficult to source part for these radios is a variable capacitor, and not finding one in his parts bin, [Jezan] decided to make his own. This variable capacitor comes directly from a ...

This process typically involves enclosing the capacitor in a protective case made of materials like plastic, resin, or silicone elastomer potting compounds. For example, aluminum electrolytic ...

They are still made, but they’re not cheap and they won’t appear so readily in your junk box any more. Fortunately a variable capacitor is a surprisingly simple device, and one you can make ...

The gradient of this graph is equal to the capacitance of the capacitor. \(C= \frac{Q}{V}\) And the area under the graph is the energy stored by the capacitor.

A capacitor made out of the precious metal tantalum. The silver-gray tantalum beads, in the form of compacted powder, can store a lot of charge relative to their mass. This enables smaller ...

Did Apple really fit a capacitor backward on the Mac LC III? A multimeter-wielding retro fan has confirmed that, yes – somebody made a mistake decades ago, and a capacitor ended up installed the ...
