battfeed

battfeed turns live battery data sources into BDF (Battery Data Format) feeds. It is the acquisition layer of an open battery-data stack: point it at something that produces battery readings — a simulator, a growing instrument log, the battery in your Windows laptop, or your own cycler driver — and it polls that source on a schedule and writes conforming .bdf.csv files (plus a .meta.json sidecar) that the rest of the stack understands.
