Car Suspsension

Ever since the earliest days of the car, suspension systems have been in use to keep the ride comfortable. Seeing as how commonplace it is for cars to have good suspension nowadays, we often take for granted just what these systems do to make our daily that much more comfortable. There are many different kinds of suspension, almost every kind involves a sort of spring. The earliest system to be used in cars was a simple spring on the frame connecting to steering frame, allowing for some amount o

Altimeters

Altimeters are used by many people in a variety of different situations, such as skydiving, flying, and even hiking. The purpose of an altimeter is to give the user a readout of their current altitude. This can be achieved in many different ways, but the most obvious method is to measure the air pressure. By taking into account the current temperature, one can calculate their current altitude. In early aircraft, this was done with analogue meters, rather than digital calculations. They weren't t

Duct Tape

Duct tape is famous for it's ability to hold things together, as it's adhesive is incredibly powerful. Duct tape is made with a woven fabric to make up the tape, which could be made of nylon or polyester. This is then coated with a layer of thin polyethylene, which makes up the tensile strength of the tape. This can hold upwards of 65 pounds before snapping, despite how thin the tape is. This makes up partially for duct tape's strength, but where it really shines is the adhesive. This adhesive i

LED lightbulbs

Conventional light bulbs use a filament, something to run current through that will heat up and produce light. These are very inefficient however, as more energy is put towards producing heat than light. This is why the idea for CFL light bulbs came about, which use a current running through gas to produce it's light. This method is more efficient, but still isn't perfect. This is where LED's come in, as they are small, very efficient, and require little power to produce a good amount of light.

Types of Touchscreens

In the last decade, the uprise of mobile devices with touchscreens has been prominent, and there are 2 main types of touchscreens. The first, and cheaper style, is known as resistive, which uses 2 separated films that when come in contact they allow current to flow. This is what is used to determine the location of the touch, as wherever the current is flowing is where the user is currently touching. The issue with this system is that it requires physical movement of the plates, meaning it can b
