How tolgaozuygur/diy_electric_salt_spoon works
This repository describes a DIY electric salt spoon: a small battery-powered circuit applies microscopic electrical stimulation between a hand electrode and a spoon-tip electrode, aiming to increase perceived saltiness. Its main product artifacts are Arduino firmware, KiCad circuit-design files, and CAD models for the spoon and enclosure. The README documents the intended electrical effect and safety constraints, but no source excerpts were provided; firmware-to-circuit wiring and detailed circuit behavior are therefore not inferred.
