Can a clock pendulum be slowed by adding a resistor to the PSB?

The discussion addresses the feasibility of slowing the swing frequency of battery-powered wall clock pendulums, originally designed to swing about 60 times per minute, down to 30 or 20 swings per minute. The pendulum mechanisms are driven by an oscillator circuit on a PCB, powered by a standard AA battery, without traditional mechanical gears. The natural frequency of a pendulum is primarily determined by its length and weight, which cannot be altered further in this case. Attempts to modify the swing rate by adding resistors or changing capacitor values in the oscillator circuit were suggested, as the oscillator frequency controls the electromagnetic impulses sustaining the pendulum motion. However, multiple contributors clarified that the pendulum's swing frequency is governed by physical pendulum properties and cannot be effectively slowed by electrical component changes alone. Lowering battery voltage is ineffective as it would stop the mechanism. The battery and oscillator only provide energy to maintain the natural swing against damping forces, not to alter its frequency. The consensus is that without changing pendulum length or mass, or redesigning the mechanism, slowing the swing rate is not achievable by simple resistor or capacitor modifications on the PCB.
