New Huntsman Thermoset Mimics Elastomers

A new thermoset system from Huntsman Advanced Materials provides elastomeric qualities, while retaining the benefits of epoxy infusion. One of the key attributes is the ability to use the material with carbon fiber systems and textiles due its low viscosity. In addition to flexibility and excellent impact strength, the unique system also provides high transparency, brightness and UV resistance. &# ... More

The Incidence of the Light Bulb Going Off (or In?)

After being fed specifications in a piecemeal fashion, an engineer figures out how to meet a test spec by thinking inside the box By Radcliffe Cutshaw, Contributing Writer The project was to design a device to segment the upstream band used by cable modems. Cable modems are collision moderated: When two or more modems try to send at the same time, a collision is detected and both wait a random tim ... More

Qosina High Flow Stopcocks with Two-Way Flow Control

FLUID POWER:   High-flow polycarbonate stopcocks with 90-degree HDPE pivot handles provide flow control from one of two female luer locks to a male spin lock. The 0.11 inch through-hole provides higher flow rates for rapid infusion. The blue (Part # 99752) and yellow (Part # 99753) stopcocks are color coded and clearly marked with a longer “OFF” handle to facilitate flow path ... More

Stealth Technology, Romulans and Teleportation

So you think stealth technology was born at the Lockheed Skunk Works in the mid 1970s do you? You really believe engineer Denys Overholser developed the equations and the F-117 Nighthawk stealth fighter was the result. You poor, deluded soul. As everyone knows, the U.S. Navy made a ship disappear during World War Two. Known as Project Rainbow and/or The Philadelphia Experiment, the ship, the U.S.S ... More

Miniature Motor Squiggles into Small Precision Devices

Look at small motors for a product design and you’ll find a gap between small DC motors and micro electromechanical systems (MEMSs) fabricated on a silicon wafer. New Scale Technologies has helped filled that gap by designing squiggle-motion motors, or squiggle motors, for engineers who need a tiny motor in miniature and subminiature applications.

The Instance of the Misbehaving Mack Mixer

An engineer experiences a Hellish ride while driving a 30,000-lb cement truck that’s losing rpms–fast! By Neil Larkins, Contributing Writer Back in 1993 I worked as a contract driver for a company that moved trucks. One evening my dispatcher sent me to a rural area outside of Washington, DC to pick up a cement truck and drive it to Miami, Florida. Following directions, I finally foun ... More

USDA Forest Service Tests Voltree Power’s Bio-Energy Harvester

In February 2009, I posted “Voltree Power Harvests Electricity from Trees without Combustion,” describing how Canton, MA based Voltree Power was commercializing a patented technology from MIT to extract energy from trees. Using the pH difference between trees and the soil, a miniscule amount of electricity is produced, which Voltree captures to power wireless mesh networks within for ... More

Cool Motor Kits for Future Engineers

Greetings fellow gadgeteers! In this blog post, I will take a look at some electronics projects for kids. Like many of you, I have kids that are at that impressionable age where they can hopefully be steered towards an honorable life spent in a field such engineering, science, or plumbing, and away from such disreputable activities as ticket scalping or lawyering. To that end I present some proj ... More

Saturn Demise Might Be Saddest Of All

The demise of Pontiac has grabbed auto industry headlines over the past few days, but little has been said about GM’s abrupt change in plans for its Saturn Corp. Yesterday, the giant automaker said it no longer plans to build Saturns through the end of 2011. Instead, it will phase out Saturn at the end of the 2009 model year. That’s sad. Those who recall the history of Saturn know th ... More

Google, Harvard's Wissner-Gross debate CO2 from Web Search

Harvard graduate student Alex Wissner-Gross created quite a stir with his claim that every web search creates between 5-10 grams of CO2 from the power required to keep those massive server farms going. Google officials apparently thought he was singling it out, but he later said he was speaking about generally about web searches and had no axe to grind with Google.But who does not equate web searc ...

Mediocrity in the Design Process: Marinara sauce gone wrong.

An end user should not be using a mediocre product, and let me explain how marinara sauce relates. Before super-mega-markets, I would imagine markets had fewer varieties of many products. Those products were likely produced to try to please as many customers’ taste buds as possible. Let me presume that customers only had different preferences between texture and spice of sauces. The two a ... More

Chevy Volt, Performance Capabilities Subject to Change

Should I be surprised given the GM’s rush to get this electric car into production by late 2010? That’s how fluid the battery situation is. The ad touts that you might seldom buy gasoline if you travel 40 miles or less ... More

When to Embark on a New Engineering Position

Should you move from that company of long standing? Are you waiting patiently for the retirement party and that “gold watch”?

With him were two of his twenty-something-year-old kids, helping Dad gather tools for a career move. They were as interested in advice for their own career ... More

Light Matters: The Unsung Heroes of Modern Health Care
First, let's define "no-compromise." In an ideal configuration, this lamp would use a high-brightness LED (HBLED) that is built into a small, integrated package and is able to produce a large quantity of focused light, operate with a high level of reliability and generate no audible noise. Is this difficult? Yes, but it is possible.
