This brief tutorial explains how the “Wiegand effect” can be used as a reliable, low-cost, energy-harvesting system to power ...
Discover Arduino Uno Q, a hybrid Linux plus microcontroller board with four Cortex A53 cores, so you get precise control and ...
Abstract: Image-based rotary sensors have the advantages of being simple and low cost and exhibit good robustness to harsh conditions. Existing image-based sensors calculate angle positions by mark ...
Abstract: In this article, we propose and experimentally demonstrate a simple and low-cost fiber-optic sensor for temperature-independent ultraviolet (UV) detection. The sensor utilizes a ...
The automotive past is often recalled fondly. A fender bender was a nuisance, certainly, but the required repair was relatively predictable. The fix generally involved a new bumper cover, some paint ...
Designed by Nova Radio Labs in the US, the Novaduino Environmental Sensor Kit is an Arduino-programmable air quality and weather monitoring solution built around the company’s own Novaduino Display ...
A Hall-effect sensor is a transducer that converts a magnetic field directly into a usable electrical voltage. It enables engineers to perform non-contact measurement of shaft rotation, detect the ...
Mr. Norris is a doctoral student at Duke University studying electric power systems. Amy Wasserman and her husband were stunned when the energy bill for their home in Wilmington, Del., topped $500 in ...
The purchase of a Broadway Limited Imports HO scale Reading Co. class T1 4-8-4 left Chris Russo wanting more — the ability to access the Digital Command Control functions built into the new model.
This post is co-authored by Molly Dickens, Ph.D. The English lexicon is always evolving to accommodate our lived reality. In the last decade, we have seen many terms find their way into the mainstream ...
Not all poisonous gases have a smell or a color. But a tiny grid of pastel- and candy-colored squares that effectively “sniffs” out hazardous chemicals in the air such as chlorosarin — a highly toxic ...
