      Speedometer Calibration

      One of the most prominent gauges on an automobile’s dashboard is the speedometer. Its primary function is to give a visual indication of a vehicle’s speed in miles or kilometers (or both) per hour. Since the majority of these devices are still analog, they may require speedometer calibration when new tires are installed, major automotive

    • What is Malleability?

      What is Malleability?

      Malleability refers to metals’ (and other hard materials’) ability to be stretched, shaped, or molded through applied pressure. While not all objects are malleable, most metals are. This is the reason that metals such as gold, silver, and platinum, are used to make jewelry and electronic circuits. Malleable objects can usually be reshaped and molded

    • Brain Computer Interface

      Brain Computer Interface

      A brain computer interface (BCI) is an external devices that communicate directly to the brain of humans or animals through neuron silicon interfaces. These external devices can either transmit or receive signals to and from the brain which can then be used to restore function or movement to sensory organs or limbs. Furthermore, these external

    • What is a Diopter?

      What is a Diopter?

      A diopter is a lens that bends light in order to magnify an object. Diopters can be used to enlarge small objects or see across far distances and are generally integrated into other objects in order to maximize efficiency and accessibility. A diopter can also refer to a measurement that describes a lens’s optical power

    • Potassium Dichromate

      Potassium Dichromate

      Potassium dichromate (K2Cr2O7) is an inorganic chemical reagent that is normally used as an oxidizer in industrial and laboratory applications. It is used to oxidize alcohols and convert primary alcohols to aldehydes and sometimes carboxylic acids. Unlike similar processes that use permanganate, only carboxylic acids result. The secondary alcohols are converted into ketones and no

    • How Safes Are Made

      How Safes Are Made

      Known under the generic name of safe or safe box there is a very broad set of constructions. From simple home safes used to keep personal documents, to bank safes which include special building construction and security measures. All safes are sturdy constructions made of metal (most with different layers) and a removable part (or

    • U.S. Drones

      U.S. Drones

      The U.S. drone program has seen significant press since the first Gulf War when the defenders of Faylaka Island surrendered to the Pioneer drone, or Unmanned Aerial Vehicle (UAV), flying spotting services for the USS Wisconsin (BB 64). Since that time, the technology powering U.S. drones has steadily improved now allowing the MQ-1B Predator and

    • What is a Peltier Cooler?

      What is a Peltier Cooler?

      A Peltier Cooler or Peltier Heat Pump is a type of refrigerator that has no moving parts and is capable of transferring heat to either side of itself. Peltier Coolers are advantageous as they are solid state devices and only require a DC electrical current in order to cool an object or area. A Peltier

    • RTV Silicone

      RTV Silicone

      Room Temperature Vulcanizing (RTV) silicone is a rubber polymer used to create molds, prototypes, and sealant. It is extremely flexible and quite tear resistant. It is made up of two separate components: a base and a curative. RTV silicone can be poured, sprayed, brushed, or pumped onto a surface. Either moisture or heat dries it,

    • Ultrasonic Humidifier

      Ultrasonic Humidifier

      An ultrasonic humidifier is a device that uses ultrasonic sound waves to create water droplets from a built-in water reservoir. Ultrasonic humidifiers are used in many homes, businesses, and warehouses to properly humidify an area without using heat. Because ultrasonic humidifiers do not use heat, they use much less electricity (approximately 93% less) than other
