Walky who? Waklie-talkie!!

By Kadewi

Intro

Can you make a peanut butter Jelly sandwich? I can. Can you make a fort? I can. But can you make a walky-talkie? Read the rest of my report if you want to find out how to make one, and lots more like what it is, History, How it works, the iphone, pencils and crayons, and cool facts.

What it is

 

This paragraph about what the walky-talkie is.  According to me, It is kind of like a phone but it is a 2 way radio. So that is what a walky-talkie is.                       

This paragraph about can walky-talkies communicate with more than 2 people. According to Keegen, Walkie-talkies are hand held devices that allow two or more people to communicate using radio waves. Most walkie-talkies let users do one function at a time (either listening or talking). They are a type of device known as a Ňtwo way radio.Ó DonŐt you think that

History

 

 

This paragraph is about who invented the walky-talkie.  According to me, The first radio receiver/transmitter to be nicknamed "Walkie-Talkie" was the backpacked Motorola SCR-300, created by an engineering team in 1940 at the Galvin Manufacturing Company (forerunner of Motorola). The team consisted of Dan Noble, who conceived of the design using FM technology, Henryk Magnuski who was the principal RF engineer, Bill Vogel, Lloyd Morris, and Marion Bond. Motorola produced the hand-held AM SCR-536 radio as well during the war. It was called the "Handie-Talkie" (HT). IsnŐt that so cool? 

 

 

This paragraph is about when the walky-talkie was invented.  According to me. The first radio receiver/transmitter to be nick-named "Walkie-Talkie" was the backpacked Motorola SCR-300, created by an engineering team in 1940 at the Galvin Manufacturing Company (fore-runner of Motorola). The team consisted of Dan Noble, who conceived of the design using FM technology, Henryk Magnuski who was the principal RF engineer, Marion Bond, Lloyd Morris, and Bill Vogel. Motorola also produced the hand-held AM SCR-536 radio during the war, and it was called the "Handie-Talkie" (HT). That is when the frist walky-talkie was invented.

That is who invented the walky-talkie.

How it works

 

This paragraph is about what is inside of a walky-talkie. According to Keegen, There are six main parts to a walkie-talkie. These items are the transmitter, receiver, crystal, speaker, microphone, and power source. The transmitter sends your voice, after it has been made into a radio signal, to the other walkie-talkie you are communicating with. The receiver picks up the radio signal that the transmitter from the other walkie-talkie sent. The crystal sets the frequency (also called a channel) that the walkie-talkies are on. They must be on the same frequency to communicate. The speaker is the part that takes the signal picked up by the receiver and amplifies it, so it can be heard. The microphone is the part that you speak into, and it converts your voice into electric signals. It is the exact opposite of the speaker which converts electric signals in voices. The power source is a type of battery, and sometimes these are rechargeable. DonŐt you like it is cool? I do!

Iphone

 

This paragraph is about what colors the iphone comes in.  According to Dachary Carey, black and white so far. more colors will probably be out soon. You can get different colored cases.

Pencils and crayons

 

This paragraph is about how crayons are made.   According to Howstuffworks Inc., the  two main ingredients in a crayon are Pigment and Paraffin wax. This mix is heated until it melts into a liquid. Crayons melt at 105 degrees F and 40 degrees C. The mix is heated to 190 degrees F and and 82 degrees C. The liquid is poured into a preheated mold full of a lot of crayon shaped holes. After that they take the crayons and put them in cool water for them to harden. The cool water is 55 degrees F and 13 degrees C. The way of hardening the mold makes the crayons in 3 to 9 mins. One mold makes 1,200 crayons at a time which ways about 40 lbs. total. The machine uses hydraulic pressure to take out the crayons from the mold. Earlier mold designs used a hand crank to push up the crayons. The left over wax to make crayons is recycled to make more crayons so making crayons is not wasteful. More than 120 crayon colors are possible and 2.4 million to 6.4 million crayons are made in a day. That's a lot of crayons. I didn't know that crayons were that popular.

 

This paragraph is about the largest pencil. According to Kedar Misani the largest pencil in the world weighs about 18,000 pounds and is 76 feet long thatŐs about 3 classes long, it has a volume of 1,900,000 regular pencils so thatŐs a lot of pencils one million, nine hundred thousand pencil I can't even imagine it. That's a lot of pencils if you ask me. It contains 4,500 pounds of graphite. The person to build the first largest pencil with a group of people was Ashrita Furman well it said that he wanted to break the world's largest pencil.  This is the best website to find out history of the world's largest pencil.

Cool facts

 

This paragraph is about if you can make a walky-talkie. According to other, Each radio needs a reciever and a transmitter. When the push-to-talk button is not depressed, the radio recieves. An optional squelch circuit can be used to mute static. When the push to talk button is depessed, the reciever is muted and the transmitter is activated. The details of this are left as an excercise to the reader. To make a radio, you may need a crystal diode. Cool donŐt you think.

 

Conclusion

So I hoped you liked my report, like the cool facts about the walky-talkie and about the largest pencil and lots more!!!
