Pencil+Sharpener+(Electrical)

=My Device (NMILLER)=

Purpose
//The purpose of this device is to be able to sharpen your pencil quickly so that you are able to write down information in school, at work, etc.//

Energy
//The pencil Sharpener gets its energy from an electrical motor inside of it, The Electrical motor gets its power from a plug that you put into an outlet. That sends electrons through the wire into the device which powers up the motor and sharpens the pencil very quickly in order for you to be able to write with the pencil.//

Controls
//The pencil sharpener consists of 2 blades. The blades are usually placed at a 23 degree angle in order to give the pencil its cone like shape on the sharpened end. Inside of the device has a little sensor so the pencil sharpener knows when to turn on and off. When the pencil enters the Pencil sharpener it hits the sensor and thats turns on the Pencil Sharpener, and once the Pencil is taken out the Sharpener is turned off.//this is the sharpeners sensor which triggers the blades ==Materials //Some materials that are essential to this device would be a pencil, 2 fine blades, a sensor to trigger the blades to rotate, and some sort of electrical plug to give the pencil sharpener power to run at all.//==

Science
//The scientific principle that is significant for this device is the electrical motor inside of the pencil sharpener and how it gets its energy. It can get its energy from either batteries, or being plugged into whichever building you are in's electrical system. Its other scientific principle is the mechanical use of it which is sharpening the pencil.//

Design
The standard pencil sharpener is designed in the shape of a cubed rectangle generally, but there are some cases where the device is designed in a different shape for show.

Evolution
//This device began as a simple mechanical machine where you would rotate the knob in a clockwise direction in order to move the blades which would sharpen the pencil. Then came the electrical pencil sharpener which is used with an electrical motor which rotates the blades, it can run on batteries or being plugged into a bulidings electrical system.//
