First we need a rectangle aluminium pipe. 

Then we need a acrylic sheet. That will cover the whole aluminium rectangle pipe only leaving the area of peltier which will touch the aluminium and will keep the peltier in a room temperature. 

From back side of the light we also will cover it with acrylic sheet. From this we will make a whole like a (i) for air circulation. That will keep the aluminium and peltier inner side at room temperature. 

 These are the some pictures those will help how the flashlight is made. About LED strawhate 8mm 0.28W will work. In my own experience 1W special LED work very well. If you find this ok otherwise do not use 1W it does not use it. You can 8mm strawhat white LED 0.28W. More about LED selection few other things you can find in instructions 

For testing our circuit it has 3 parts peltier module, volt boosting circuit and LED. 

When we put our hand on Peltier. With the hand of our heat peltier module produce about 30mv to 40mv. Then volt boosting circuit take 30mv to 40mv from peltier and convert it into 2.5v and send it to LED. When LED receives 2.5V it starts running. 

All human are equal. We born equal. But source of education is not equal for every one 

I always think education is the right of every one. One some cases many people cannot reach on their goal because of electricity and light. I think with this project our people will have source of light. With this they can get education at night without worrying about batteries. Light sources that always remain in your hands with taking tension about battery are charring.  A headlamp that always remain on your head at study time. Sharing this project to hackaday community that anybody can build this. Without worrying about that they no knowledge about science.
