Abstract
We construct electronic oscillator from acellular slime mould Physarum polycephalum. The slime mould oscillator is made of two electrodes connected by a protoplasmic tube of the living slime mould. A protoplasmic tube has an average resistance of 3~MOhm. The tube's resistance is changing over time due to peristaltic contractile activity of the tube. The resistance of the protoplasmic tube oscillates with average period of 73~sec and average amplitude of 0.6~MOhm. We present experimental laboratory results on dynamics of Physarum oscillator under direct current voltage up to 15~V and speculate that slime mould P. polycephalum can be employed as a living electrical oscillator in biological and hybrid circuits.
