Nathan Lodenís Magnetic Levitation experiment started with the basic problem of stabilizing a frictionless position control loop with inherent metastability. A fast controller with phase-lead compensation took care of that. Then he discovered a strange phenomenon: The levitated object begins and continues oscillating in rotation about a vertical axis. Explanations have been proposed and discussed, but they remain theories. Can you reproduce his result and discover the cause? The apparatus consists of a wooden frame, a bolt with a coil, a power transistor, an infrared emitter and detector, a few op amps and passive components.
These are the toys that inspired budding engineers to try out sublime designs, create miniature structures, and experiment with bizarre contraptions using sets that could be torn down and reconstructed over and over.
PowerStream is deploying the microgrid at its headquarters to demonstrate how people can generate and distribute their own energy and make their homes and businesses more sustainable through renewables.
