The Sputnik automaton consists of an illuminated, handmade globe around which a model of the Sputnik1 satellite orbits. Like the original, the beeper circuit consists of an astable multivibrator, a Wien bridge oscillator, and an audio amplifier. For this purpose, 6 Russian germanium pnp transistors of type MP40 were used. The diode is made of the semiconductor material germanium as well and also comes from old Russian stocks. The wooden housing is designed to match the typical furniture of the time.
