Considering a design project here.
As an electrical engineer, I am well versed in the concept of the PLL - Phase Locked Loop.
What i am pondering is the idea of replacing the VCO with a mechanical oscillator that can have it's resonant frequency adjusted by a control signal. If the length of the pendulum could be dynamically adjustable via electro-mechanical means, it seems like it would not be hard to close the loop and achieve phase-lock with an external clock.
My idea is to have a linear array of pendulums that are constrained to a single axis of freedom, and have the ability to phase lock them to an external multi-phase clock.
The effect could be spectacular, as you could make them perform in beautiful patterns that could evolve from one to the next, by re-phasing the clocks and allowing the pendulums to come back into lock.
Any ideas on this one?
