Solar Mobile Charger

Solar mobile Charger is a device by which u can charger your mobile phone using Sunlight. This is a easy to make Solar Mobile charger which you can make at home without any Problem. There are make Solar mobile chargers on the net there but they all lack a few things which I am going to cover in this Topic here. I have included a Voltage regulator IC (LM317).It regulates the Voltage given to the Phone. SO even if the Voltage produce by the solar panel is 3V you can still charge your mobile phones. Check it out here

Variable DC Supply

This is another Modification of the A to DC converter. Instead of having just a fixed Voltage supply you can just add a variable resistance to the circuit and adjust the voltage according to your own need.

For doubts Comment :)

5V DC power supply

It is a modification of the A to DC converter . This is the regulated Form of the ac to dc Converter. We can get a 5V supply using it .
See it in the Projects list .
Comment if u have any doubts:)

AC to DC Converter

It basically coverts AC supply into DC supply . With Some modifications in the circuit you can make a regulated power source. I will be uploading it in the next post.

Check out the AC to DC converter in the projects list. :)
Ask in the comments if you have any doubts.

Dark activated light

Hey guys,
         I have uploaded the next project "Dark Activated light".I have used very simple components to make it. I have used a LED as a load. But you can also use relay to operate bigger things like a lamp.
Check it out on the projects list------------------------------------------------------------------------->
Please comment if don't understand :)

Next Project

My next post will be " Dark activated light"

This is a automatic system using which you can turn on the light as it becomes dark.

Its easy to make and pretty useful.  

Hey guys,
I have made this little blog for Students of high School and engineering grads,who are interested in making cool projects.You can use them for your school or also as  collage  projects.I will soon be uploading many more projects.:)
