=iPod FM Transmitter= ahelsel12

Purpose
To listen to your [|apple]iPod through your car speakers so everyone around them/you can hear the music on your apple iPod.

Energy
The iPod FM Transmitter gets it's energy from the car's battery that it's plugged into. This device will only work when the car is turned on, or else it wont be able to get the right resorce of energy to turn on. The battery in the car gives the car energy to start the engine. After that, the energy gets transfered into the car's dashboard where the radio is located. With that being said, the iPod FM Transmitter will be able to work because it's plugged in to or connected to your radio so that you are able to listen to the songs on your iPod through your car's speakers.

Controls
The controls that are on this iPod FM Transmitter are shown in the picture to your right. You have the arrow buttons that let you change and choose what song you want to listen to. Another control is your iPod that connects to the plug looking object in the bottom right hand corner of the picture. You are able to change the song through your iPod if you wanted to.

Materials
In order for this iPod FM Transmitter device to work you will need: 1. An iPod (The iPod must have songs on it or you wont be able to hear anything) 2. Any type of transportation that would let you have access to the radio. 3. Working speakers in your vehicle 4. Any type of iPod FM Transmitter. 5. And of course working ears. How else would you hear the music.

Science
The scientific principle of my device is EM Radiation. The iPod FM Transmitter acts like a radio because when you connect it to your car and to your iPod you can hear the music.

Design (Refer to Picture Above)
This device looks like a phone charger that you would plug into your car. The only difference is that there is a tiny little screen and buttons on the bigger part of the FM transmitter. Connected to the bigger part of the transmitter is a wire that runs about a foot or two long. On the other end of that wire is a little rectangular plug. This rectangular plug gets connected to the iPod itself through the charger slot of the iPod. (the charger slot is usually located at the bottom of the iPod)

Evolution
Changes have occurred to this device already. The iPod FM Transmitter used to have a casset that you had to put into your car to listen to your iPod. After that you had to plug it into the lighter jack. Now there is the latest wireless FM Transmitter that you only plug into your iPod and the car's antenna picks up the radio waves/signals from your iPod that lets you listen to your song through your car radio.
