Improvised lamp made of a dynamo and bike lamp
The three main parts that make this improvised lamp are a bike lamp, a dynamo and two handles one of which is movable and the other fixed. The fixed handle is used for guiding the lamp, while the movable handle on the right is used as a crank.
Fast speed movements of the crank make dynamo act as a power supply for the bike lamp, which enables the creation of light beams. Although it seems primitive, this invention was of extreme help for the people during the years of war.
This simple, improvised lamp is another in a series of proof of human ingenuity and perspicacity, even in extremely difficult circumstances.
