Make Your Own Hygrometer

Posted by Manju in Science And Technology

You don’t have to be a weather man. Just for fun, it’s not that harder to make a simple weather hygrometer. It is easier than most people thought. However, it’s not that easy to make NOAA weather radios and you will have a whole lot of fun while you are at it. There are several things you will need before you get started. These include a thin, flat piece of plastic you can cut and a flat piece of styrofoam or word that is about 9 inches by 4 inches. You will also need two nails, three eight-inch long strands of human hair, a dime, tape, glue, hammer, scissors, and a pattern. All you need to do is cut the plastic into a triangle and then tape the dime onto the point of the plastic. You will need to poke a hole in the base of the triangle with one of the nails in between the nail and the dime you need to glue the hair strands. Then you need to take the pointer and position it on the base only a quarter of the way up the side. Then, attach the nail to the base. The pointer should be able to turn easily. You will know you have it right when the hair hangs vertical and the pointer is horizontal. Then, glue the hair to the nail. The hair will show you how much moisture is in the air by expanding or contracting due to the humidity.

Garmin Aviation GPS

Posted by Manju in Science And Technology

Anyone interested in aviation will need an aviation headset as well as some knowledge about GPS and how it assists pilots. One of the best GPS on the market for aviation is Garmin aviation GPS. The following information will show how the Garmin aviation GPS works and why it is important for pilots.

First of all, GPS stands for Global Positioning System. GPS relies on a network of 24 satellites to assist in navigation. The satellites are in space thanks to the US Department of Defense however everyone can use the technology if they have a GPS system thanks to the system becoming available in the 80s for use by al. GPS works despite the weather, location, and time of day. GPS is free to use although the actual device to detect the signal must be purchased.

The satellites in space that are used for GPS circle the earth two times every day in a fixed orbit. The information that is gathered is then transmitted back to the earth. GPS receivers like the Garmin aviation GPS then receive the information. Once the information is received by the receiver triangulation is utilized to determine the specific location of the user. It’s interesting how GPS actually works because with so much transmitting and time difference it would seem the Garmin GPS could get it wrong. However the receiver simply notes the time a signal was received by a satellite in comparison to the time it was sent. The difference in time allows the receiver to determine how far away the satellite is in space.

Fortunately, GPS is unbelievably accurate and users can count on the GPS system to give them accurate information. The reason why it is so accurate is due to parallel multi channel design. Garmin’s receivers offer 12 parallel channels and as soon as the receiver is turned on the signal is picked up and locked onto. Then, no matter whether the user is in a location with tall buildings or lots of foliage the lock is maintained. There are some things that may change the accuracy of Garmin aviation GPS including atmospheric changes. However, on average, these receivers have an accuracy of 15 meters.
