Electrical circuits have always been a mystery to me. Those tiny components that look like Chiclets or jewelry beads somehow make a light blink, produce music, and detect motion. So I was happy to ...

When looking for things to write about, there is nothing we like to see more than well-documented schematics and code available for download. In the case of schematics, we realize that they can be a ...

A new theoretical study has taken a close look at how noise influences these circuits. The results show that noise places a surprisingly strict limit on how deep a quantum circuit can be, meaning how ...

Imagine you're trying to build a very long, complicated chain of dominoes. The aim is that each domino hits the next one perfectly, all the way down the line, producing an amazing result at the end. A ...

This code was created in 2001-2004 when I taught Borland Delphi 3 to myself. It contains many, many global variables, unstructured and undocumented procedural code and bad variable names. If you don’t ...

A branch circuit consists of the conductors between the final overcurrent protection device (OCPD) and the point of use outlets [Art. 100] (Fig. 1). Article 210 ...

Article 210 contains the requirements for conductor sizing, conductor identification, overcurrent protection, and GFCI and AFCI protection of branch circuits. It also contains requirements for ...

In the comment section of my last article, there was some great discussion about drawing schematic symbols. It is important you make your schematic symbols understandable. Sometimes, the pre-packaged ...
