electroplater

Continuous-rotation servo speed control for a WEMOS D1 mini (ESP8266), with potentiometer input — a small board that turns the dial's quiet rotation into a stroke exactly as fast as asked. The WEMOS reads the potentiometer and answers the servo's speed in kind: no faster than the dial says, no slower — the evenness of the coil made electronic. The bench it sits on is the plating bench, which is where the board gets its name. It exists because the steady hand is the whole craft: precision at the dial is cheaper than a jeweler's nerves, and the old smiths knew the even stroke was worth more than the strong one.

Gold, the old smiths agreed, was mostly a manner of application — the craftsman who could coax a skin of it onto copper was worth a room of miners, because the shine was a truth told thinly, and the thin truth held. The electroplater's bath is the gentlest of the smith's instruments: no hammer, only patience, current, and the quiet argument of metals in water. But a bath needs a steady hand at the dial, and so the same bench carries its other talent — continuous-rotation servo speed control for a WEMOS D1 mini, the ESP8266 reading a potentiometer's turn and answering with a stroke exactly as fast as asked, no faster. The ancient jewelers drew their wire by hand at evening and called the evenness of the coil a virtue; this board turns a servo the same way, governed by one small dial and the attention of whoever is holding it. Lugh's spear never missed, says the tradition, and a well-trimmed pot is the modern succession of the same discipline. The moss grows along the bench where the wires rest, and it is gold at the edges where the bath has been.
