Demonstrations-Analogrechner (DIY Miniatur-Analogrechner)

A 9-page German technical description by F. Vogel (2009) of a self-built miniature demonstration analog computer housed in a 188×120×77 mm aluminum enclosure. The machine uses BiFET op-amps with ±10 V machine units and provides 2 integrators, 3 summers, an open amplifier/inverter, 4 ten-turn coefficient potentiometers, a translinear multiplier unit (multiply, divide, square, square-root to ≤0.3% error), and a diode function generator for sine. Auxiliary features include a triangle-wave generator (1.5–75 Hz), 12-position address selector, overload indicator, and ±15 V DC/DC supply powered from a 9 V external adapter.
