Auto-ranging datalogger concept
An ESP32-based auto-ranging current/voltage datalogger — never taken to completion, but far enough along to be worth a mention.
The idea was a general-purpose logger that could automatically range itself across a wide span of currents and voltages, rather than needing a fixed measurement range picked in advance. It got as far as a populated ESP32-based board before other projects took priority — parked as a concept rather than pushed through to a finished tool.
