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/
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
