Introduction: How to Make a Solar Backpack
Last year , i was trekking in the mountains and was surprised by the lack of electricity. Although there was an abundance of sunlight during the day, all lighting there during the evenings/night was with oil lamps which not only smoky but provided very little light. Vowing to return next year better prepared, i made a solar backpack. It can be also used to power widgets such as the arduino, raspberry pi, etc. Here are the features:
Can charge upto 6 mobile phones at one time!
140 lumen high power led lighting
27wh high capacity battery
Modular Design for expansion
