Written guides on the gap between a datasheet and a working board — why a 10 µF capacitor measures 3 µF under bias, when a tolerance stack matters, how to read the ratings that actually limit a part. Measurements and worked cases, not formula sheets.
This part of the site is in development. Below is what is being built for it.
Every calculator already carries the theory for its own arithmetic. These go further, into the behaviour a formula does not capture.
