Solar Mobile Phone charger complete circuit diagram

Solar Mobile Phone charger Circuit:

Here is another idea of harvest Solar energy for charging.This charger can charge almost all types of batteries such as Mobile phone batteries. It uses a solar panel to convert light in to electrical energy.
This circuit explains itself whole procedure.

Click to zoom

A 12 volt and 5 watt solar panel is used as source of current.The cells in the panel are made up of semiconductor material which convert sun light energy in to electrical energy.
When the sunlight is a peak means maximum, then solar panel can generate upto 16.5 volts with 400mA current.This current is able to charge mobile phone battery.
Diode D1 allow current to pass in to three regulator ICs to get regulated output.
This output voltage is able to charge Lead Acid battery.
The battery can be connected to point C and ground.
IC2 gives regulated 6 volt to charge NiCd battery. IC3 provides regulated voltage to charge all types of mobile phone batteries which is rated at 3.6 volt.
Red led indicates its charging the battery.

Ubuntu operating system in Moble phones

 Ubuntu operating system in Moble phones


Short Review:

Canonical has lanched the mobile based on their Linus-based Ubuntu operating system.Ubuntu operating system for mobile phones uses the same basic kernel and drivers as Android operating system, but it has brand new GUI interface and navigation.

Those who had used Ubuntu operating system in Computers they are waiting for this but for those who don't know about Ubuntu feels them different when using this
.
For newbies Ubuntu makes the use of Gestures for the navigation around. Short Swipe form the the left shows your favorite apps, long swipe gives you all your apps.
This operating system has alot of new features like HTML 5 web apps.This Phone is alot has some Android kernel.

It allow you to dock your phone and can connect it with the keyboard and mouse for a desktop PC  experience like Motorola promised with Webtop docks.

Last Words:
                    As Ubuntu is known as secure operating system so, i thing it will be bug free mobile phone and will compete all android phones in market for making space in smartphone market.
I am waiting for this mobile phone what about you?

Why does voltage lead current in an inductor?

Why does voltage lead current in an inductor?

In inductor is an electrical component which stores energy in the form of magnetic flux. In its structure, it is made up of wires like copper wire in the form of coil around a medium.

When voltage is applied to inductor it causes current to flow through the coil of inductor as a result causes flux from each turn of coil.
