Solid-State Lighting Solutions Project

Electronics system control, “green design,” and energy efficiency are important topics in industry and academia. Here we look at a project from San Jose-based Echelon Corp.’s 2007 “Control Without Limits” design competition. Designers were challenged to implement Pyxos technology in innovative systems that reduced energy consumption. Daryl Soderman and Dale Stepps (of INTELTECH Corp.) took First Prize for their Solid State Lighting Solutions project.

So, how does it work? Using the Pyxos FT network protocol, this alternative lighting project is a cost-effective, energy-efficient solution that’s well-suited for use in residential, commercial, or public buildings. You can easily embed the LED lighting and control system—which features SSL lighting, a user interface, motion detectors, and light sensors—in an existing network. In addition, you can control up to five zones in a building by using the system’s fully programmable ESB-proof touchpad.

This winning project, as well as others, was promoted by Circuit Cellar based on a 2007 agreement with Echelon.

 

 

 

Improved Radiation Meter Webinar

Want to learn about Elektor’s improved radiation meter? On February 16, Elektor technical editor Thijs Beckers will host a webinar at element14 about the radiation meter, which is a DIY system that can measure alpha, beta, and gamma radiation.

According to Elektor, all that’s required to measure radiation is “a simple PIN photodiode and a suitable preamplifier circuit.” The system features “an optimized preamplifier and a microcontroller-based counter. The microcontroller takes care of measuring time and pulse rate, displaying the result in coun

ts per minute.The device we describe can be used with different sensors to measure gamma and alpha radiation. It is particularly suitable for long-term measurements and for examining weakly radioactive samples.”
