Small test strips made of silver or other metals, called “coupons,” are frequently used to assess and predict the speeds at which metals used in outdoor environments—pipelines, aircraft, bridges, as well as countless other types of infrastructure and machinery—will succumb to corrosion.
The BareDuino Nano is the world’s smallest Arduino compatible board. It was designed by a very young maker, Niek Blankers, aged 15, from the Netherlands. Niek has been interested in electronics since he was less than 8 years old. A couple of years ago when he was given the first Arduino board, he fell in

Recent studies from two research teams at the Polytechnic Institute of New York University (NYU-Poly) demonstrate how underwater robots can be used to understand and influence the complex swimming behaviors of schooling fish. The teams, led by Maurizio Porfiri, associate professor of mechanical and aerospace engineering at NYU-Poly, published two separate papers in the journal PLOS ONE.
(Phys.org) —Startup Play-i has created a crowd-sourcing campaign to gather funds for building and selling its pair of robots called Bo and Yana—both are part of an overall toy design to teach children as young as five years old, to program a computer. The idea, the team says, is to get children interested in programming by making it a part of storytelling.

Forecasting Future Trends Futurologists predict likely futures through refined and systematic versions of the same methods we use every day: brainstorming ideas imagining situations (gaming, scenario building) considering the past (historical analysis) gathering opinions (polling) following trends (scanning, trend analysis and monitoring) picturing desirable futures (visioning) Of course, they take a wider view and employ

Meltdown: Thermal Transfer Fax Machine Though thermal paper is still useful for thermal printers of receipts and bar codes, a different kind of thermal method has taken over for most modern thermal fax machines [source: Sems]. Whereas thermal paper allows for direct application of heat to the paper, the thermal transfer method uses a third

Cell phones are complex electronic devices, sensitive to heat, cold and excess moisture. But a cell phone’s sensitivity isn’t limited to extreme weather conditions. Analog cell phones, as opposed to the newer digital phones, can be cloned. This means that someone can tap into your cell phone’s personal identification number and makes calls on the

Reality Show Structure So, just how real is reality TV? While it certainly varies from show to show, consider this: All of the concepts were created by someone (usually the producer), the people who populate the show were auditioned or hired in some way, and, while the footage may be real, it is usually extremely

Traditional speakers produce sound by using an electromagnet to move a flexible cone back and forth. They use drivers to help translate electrical signals into physical vibrations so that you can hear recorded sounds. A tweeter is the type of speaker driver that produces the highest range frequency. The other two main drivers are woofers
