What’s The Difference Between A Stepper Motor And A Brushed DC Motor?

There have been several different types of electric motors in use for decades, and all of them drive mechanisms or something similar. What sets stepper motors apart from brushed DC motors? Brushed DC motors are designed to rotate their shafts continuously and are used in applications where they are not required to make precise movements…

Blowers Vs Axial Fans: Which Is Better For Your Project?

Blowers, otherwise known as centrifugal fans or squirrel cage fans are devices that draw air through enclosures. Common applications for blowers include: Laptops. All-in-one PCs (example: iMac). Rack servers. Forcing air through the heating element in a rework station. Certain video cards. The primary purpose of a blower is to generate a higher pressure than…

A Greener Insulation Has Been Developed Using Wood

The Fraunhofer Institute for Wood Research has developed a non-toxic insulation using wood, which is renewable, instead of petrochemicals. They claimed that it insulates as well as traditional polymer-based foams.   “Our wood foam can be used in exactly the same way as conventional plastic spray foams, but is an entirely natural product made from sustainable…

A New Superabsorbing Design May Reduce The Cost Of Thin-Film Solar

Originally published on Cleantechnica. By James Ayre. Thin-film solar cells may soon possess the ability to absorb a notably larger portion of the light that strikes them, thanks to the recent development of a “superabsorbing” design by researchers at North Carolina State University. As well as improving the light absorption efficiency of thin-film solar cells,…
