Logging Bench Supply

The question

Why does a bench supply show you the current right now and remember nothing? Half of debugging is asking what the current did thirty seconds ago.

Where it stands

Unbuilt, and it keeps growing every time it is discussed — which is why it is on this list rather than the active one. The minimum version is a logging shunt that sits between any existing supply and the board under test. The version we keep sketching is a whole supply, and that is a much larger project.
