Good afternoon, dear experts and participants of the conference "Step into the Future". My name is Maria Popova, and my name is Alexander Popov. We are students in the circle "Young biophysicist" Palace of Children's Creativity, students 10 class of school "Aiyy Kyhata". Here is the work of "Innovative use of computer mouse."

The urgency of our work lies in the fact that you know computer mouse - a device that allows you to select any objects on a computer screen and manage them, it is already so familiar subject in our lives, it seems, there is certainly no may lie in wait for any surprises. However, it happens that completely familiar products have not quite obvious properties and functions. A disassembled and slightly changing the mouse scheme, we want to show other applications for everyday life. And the most important thing in this device - it is its simplicity and accuracy of data transfer to a computer.

The aim of our work is the use of a computer mouse for the manufacture of devices with data transfer to a computer.
In accordance with the purpose it was necessary to solve the following problems:
1. To study the theory of
2. Apply a computer mouse for the manufacture of devices
3. To test devices
4. Make conclusions and recommendations
STEP 2: Apply a computer mouse for the manufacture of devices
We used a laser computer mouse to calculate wind speed. This device is called ANEMOMETER.
And why anemometer?
The use of the anemometer is widely used in many professions. But in many schools no anemometers, and in fact, many students choose the profession is, in which the flow of wind plays an important role. And making this device with the help of a computer mouse, we want to show is the possibility of a simple computer mouse.
Our anemometer is made up of a computer mouse with a simple interface with a computer mouse connect USB, desktop tennis balls, drive and telescopic antenna.
Dismantled mouse. They took out the scheme. Then we take a segment of the telescopic antenna, and solder it to the wind turned the cup axis. Axis A according to a torque mouse wheel. Mouse respectively transmits impulses to the computer.
We also used the opportunity to a computer mouse to remove the meter readings to your computer.
Mouse dismantled, removed the circuit. Taken from the phototransistor photoelectric because the sensitivity of the phototransistor mouse itself was very weak. Next solder the phototransistor to the cap of Fanta juice, to lower toward the light, and the light shines it from the counter. We connect phototransistor to the center mouse button.
Use the program, it is considered trafficking and pulses (clicks wheel and center mouse button) Mousotron 9.0. and a program that displays flicks through the formula, written in Microsoft Visual Studio.
And to show this on the experiences we have made a demo circuit energy meter.

STEP 3: To test devices
Tested devices.
Anemometer piloted in Yakutsk and houses for domestic fans.
A device to check the meter counts the pulses on the demonstration circuit energy meter, which themselves have made.
What we got with experience
Wind speed
Downtown
398 clicks specify this number in the program wind speed for 10 seconds is:
V = 0.55196
Fan (House)
607 clicks within 10 seconds to set this number in the program
The wind speed is equal to:
V = 0.841808

power consumption
Indicators when the kettle
105 pulses per minute for 1 hour then 6300 pulses
A = 3200 (imp / (kW * h))
Power consumption: 6300 (imp * h) / 3200 imp / (kW * h) = 1,96875 kW
Conclusions and recommendations
1. learned theory
2. Applying a computer mouse for the manufacture of devices
3. Proven equipment
4. Conclusions and recommendations for the assembly ....
