Energy Efficient Charge Light using Microcontroller Based charging Station

Project::"Energy Efficient Charge Light"
Condition: Tasted
Participation:: "South Asian Youth Society " under U.S Department of State
Business type: Social Business
Research : Syed Razwanul Haque (Nabil) , Arpon Anup, Robi kormokar, Nurul Huda Shipon
Group in Workshop : Youth Wave
This is a simple Home made charge light. But difference between an Ordinary chines charge light and this charge light is Energy efficiency.I last charged it 2.5months ago and using regularly. Its still illuminate me. It only consume 45mA current but illumination is good enough. I used rechargeable battery which is basically waiting for go Dustbin. But well enough for this purpose. So its also save Environment polluted by Solid form of Acid. In todays Workshop Our team name "Youth wave" planned to use such kinds of Lamp in our remote area of Bangladesh. Their is a server charge station running by solar panel or other ways. After 15 or 30 day village people go to this station and recharge their lamp. so we dont need individual solar panel which is cost efficient. We just collect 15taka from then once a month where 1 litter carosine cost more then 60tk. Its also a idea by which we can replace chines Technology by our local Bangladeshi Technology. I am not kidding you. it already proved in my room Lab yet it unploughed from charger. So if u dont believe me you are cordially invited in my room. For more info you can visit www.facebook.com/OishiElectronicsSylhet and my site www.nabilphysics.blogspot.com

Charging Technology will be used :
Our charger station will be fully automatic and we will use Microcontroller based intelligence charging technology. As we collect battery from waste we do some catagory wised programming to ensure proper charging within short time which as well increase battery life. Simple PIC 16f72 will be good choice. Maintenance of this charge station also very much easy.

Parts list for lamp: 3 resistance (220ohms) , one switch,usb port,battery(collected from waste),L.E.D,etc.

parts for Charger station: Microcontroller ,Solar panel, Battery,port ,etc

Safe your facebook Account from Hackers and Phishers

Safe your facebook Account from Hackers and Phishers

1) During login use username Instead of full email address. 

 2) Make your facebook related email hide so that it hard for a hacker to identify your email which could be the primary target for Hackers.

 3) Always look your browser address bar and make sure www.facebook.com is correctly spelled. Phisher make exactly same page like facebook and link almost like facebook.but if you look closely you can see the link is wrongly spelled. Remember Phising is more dangerous then hacking. 

4) From privacy settings set only friend can send you facebook message. 

 5) Don’t click any unknown message or link. 

 6) Hide your friendlist. 

7) From Security settings enable security browsing,enable login notification, enable , login approval.

 8) (very imp step)To avoid phising Use your mobile no as login approval(Account settings>Security>login approval).so every time after giving password a code will come to your mobile no and u can only login when you give the code.

 9) Its batter to add double space or d as your last word of your password. Most of the phising code has default after pass code.so phiser may confused about your password and default code. 10) Enable security question and set security question answer wrong. So hacker cant gauss your answer. 

11) Make sure your computer has no hidden key stroke logger. 

12) Make at least three trust friend. 

13) Use auto script block software like avg. Change info sometimes. 

 14) Use multiple admin for group or page 

 15) Mind it facebook authority dont send you any information through facebook message.so be careful it could be phissing activity.
