Tiniest Drill

This drill is about the smallest i have ever seen. The word drill in this case is a bit of a hyperbole as it doesn’t actually do any drilling. It will however spin the drill bit upon pressing the trigger, and that’s close enough for us. Plus, who’s ever heard of a drill you can wear as a pendant? That’s pretty sweet!

hybrid energy system

hybrid system refer to a home wind or solar power system that can be connected to a national grid system,  hybrid system is many advantages over signal power generation because it combine wind, electrical, solar and photovoltaic technologies in a single one.

in many area when the wind pressure is greater in one season and solar is less, or solar is greater and wind is less, etc hybrid system is the best option for these areas, for the time when neither the wind neither the solar system are , most hybrid system provide power through batteries or engine generator using fuels such us diesel etc, if batteries low then generator provide the power.

many system are stand alone system which operate off grade, i.e not connected to any system, to store the power which is produces its advisable to purchase batteries, and a charge controller.power condition equipment , safety equipment , metering and instrumentation.

Projectable Virtual Keyboard.

Projectables Virtual Keyboard.

The device simply projects the laser image of a keyboard onto a plane surface. Just type on that keyboard

A projection keyboard is an  input device  of a computer whereby the image of a virtual keyboard is projected onto a surface: when a some one  touches the surface covered by an image of a key, the device records the corresponding keystroke.

its was first invented by IBM engineer  in 1992,

in this keyboard a sensor is used which convert the movement of the finger into identical action by using software , in some keyboard infrared rays is used over the surface of the light , when some one tough the virtual button , infrared rays reflect from the finger of the user and back to the projector, which passed through an infrared filter and on the way is pass through a camera which measure the angel at which these infrared rays were reflected and sense back by the projector, which use a software and identify the virtual button which was press by the user. the diode used in it is infrared red laser diode and the sensor is CMOS sensor chip.

user can connect this virtual keyboard to computer by either usb or through usb port.

Request a new IP address from your ISP server

Here's how to do it in windows:
1. Click Start
2. Click run
3. In the run box type cmd.exe and click OK
4. When the command prompt opens type the following. ENTER after each new line.

ipconfig /flushdns
ipconfig /release
ipconfig /renew
exit
5. Erase your cookies in whatever browser you are using.

Frequently you will be assigned a new IP address when this happens. Sometime you will, sometimes you will not. If you are on a fixed IP address, this method will not work. If this works for you, you may want to save the above commands into a batch file, and just run it when you need it.

how to calculate electrical bill of your home

                             

let us suppose your home load(fan,bulb etc) connected to the main supply , remain on during the following hours .

Time                 No                       Power                            Name

6pm to 12am           1                               1000w(1kw)                             Air conditioner 

6am to 10am           1                               2000w(2kw)                             washing machine 

6am to 9am             5                               100w( 5*100w =1kw)               bulb

   

                        Now the total unit consumed in the given hours will be 

                        E = 1 kw*6 hour + 2 kw*4 hour + 1 kw*3 hour =17kwh = 17 units 

if the electrical unit supply to you, by an electrical company at a rate of 2$/unit, then your exist electrical bills during the above hour will be 17 units*2$ = 34$ daily 

and your electrical bill for the whole month will be 17 units* 2$* 30 days = 1020$/months
