Nathan Loden’s 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.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
