A hobbyist article describing the construction and theory of a simple three-potentiometer analog computer originally published in the Italian magazine Sperimentare (July 1968, "Archimede, calcolatore elettronico") under the initials GAU. The device uses a 9 V battery, two 10 K and one 1 K wire-wound potentiometers, and a centre-zero microammeter to perform multiplication, division, squaring, and square-root extraction on numbers from 0 to 10 with approximately 5% accuracy. The reproduction adds a trimmer-and-resistor retrofit (DIV x10 mode) for quotients exceeding 10, provides step-by-step calibration and operating procedures, and derives the underlying potentiometric-bridge mathematics.
