Electric Cars Do Not Pose Elevated Risk of Cancer from Electromagnetic Fields, Experts Say
Not only have electric cars become a reality, but they have become increasingly more a part of everyday life. However, while the vehicles may be good for the planet, some people are worried their magnetic fields may not be safe in regards to the driver’s health. Recently, a study conducted by seven countries has … Continue reading Electric Cars Do Not Pose Elevated Risk of Cancer from Electromagnetic Fields, Experts Say
Harvest Energy While You Munch Away
Researchers in Canada developed a chin strap that can harvest energy from the movement of your jaw. The researchers are hoping the device can generate enough electricity from eating, chewing and talking to power a number of small devices including hearing aids, electronic hearing protectors and communication devices. The initial results of the device’s … Continue reading Harvest Energy While You Munch Away
How to Make an Electric Microcontroller Patch
A microcontroller is a small computer on a single integrated circuit containing a processor core, memory and programmable input/output peripherals. Microcontrollers are designed for embedded applications, in comparison to the microprocessors used in personal computers or other general purpose applications. Microcontrollers are used in a wide variety of automatically controlled products and devices. Microcontrollers … Continue reading How to Make an Electric Microcontroller Patch
Webcast About Great Battery Experiments from Iron Science Teacher
In a parody of the cult Japanese TV program, “Iron Chef,” here is an excellent video where a live audience at the Exploratorium, in San Francisco, cheer on competitors in a fun science cook-off, where teachers compete for the sought-after title, “Iron Science Teacher.” The Exploratorium’s Iron Science Teacher competition showcases science teachers as … Continue reading Webcast About Great Battery Experiments from Iron Science Teacher
Major Increase in Production of Hydropower Expected this Decade
A major increase in the construction of hydropower dams is underway, mainly in developing countries and emerging economies. Since this trend is expected to double global electricity production from hydropower, it could reduce the number of our last remaining large free-flowing rivers by about 20 percent and pose a serious threat to freshwater biodiversity. … Continue reading Major Increase in Production of Hydropower Expected this Decade
What is a Square-Wave
A square wave is a non-sinusoidal periodic waveform (which can be represented as an infinite summation of sinusoidal waves), in which the amplitude alternates at a steady frequency between fixed minimum and maximum values, with the same duration spent at minimum and maximum. The transition between minimum to maximum is instantaneous for an … Continue reading What is a Square-Wave
What is a Sine Wave
The sine wave or sinusoid is a mathematical curve that describes a smooth repetitive oscillation. It is named after the function sine, of which it is the graph. The sine wave occurs often in pure and applied mathematics, as well as physics, engineering, signal processing and many other fields. The sine wave is … Continue reading What is a Sine Wave
New Battery Technology in the Form of Recycled Tires
Researchers at the Department of Energy’s Oak Ridge National Laboratory claim that recycled tires could see new life in lithium-ion batteries that provide power to plug-in electric vehicles and store energy produced by wind and solar. By modifying the microstructural characteristics of carbon black, a substance recovered from discarded tires, a team led … Continue reading New Battery Technology in the Form of Recycled Tires
Make a Blinking Top Hat
Arduino Pro Mini The Blinking top hat was created by a couple of do-it-yourselfers to give as a gift at their friends’ engagement party. As the hat is tilted it lights up with rotating effects. The blinking top hat combines white LED strips, a small Arduino Pro mini and an accelerometer to obtain the really … Continue reading Make a Blinking Top Hat
