We wish that all the beautiful animations that are available today to understand math and electronics had been around when we were in school. Nonetheless, they are there for today’s students and ...

Small inductance changes on the order of 0.01% can easily be sensed over a wide range with a simple circuit connected to a serial port (see the figure). Using a classic Colpitts oscillator interfaced ...

Glen Chenier’s blog I reposted yesterday got me thinking about other LC measurement techniques, including an inductance checker I built about 40 years ago and haven't used in nearly as long. The ...
