Crafting a panel meter calculator with floating point
tech
Michał Zalewski built a calculator from seven panel voltmeters—six generic units and one vintage meter—as its display. Per Adafruit Blog, he controlled it with an eight-bit microcontroller rather than pursuing a complex analog design. The project documentation and code are now open-source for other makers to build from.
