In this video, I have run a 3-wing propeller connected to a DC motor without using a battery. Instead, I used a dynamo motor and a bicycle wheel to power it.To make this project, you need two DC motors, one switch, and a 3-wing propeller. First, connect the propeller to the shaft of one DC motor. Then, connect the wires of this motor to a switch, and from the switch, connect the wires to the second DC motor.
Attach a toy car wheel to the shaft of the second DC motor. Use glue to fix all the components onto the body of a bicycle. When the switch is turned on and the toy wheel (connected to the second motor) is brought into contact with the rotating bicycle wheel, the second motor starts generating electricity. This electricity powers the first motor, causing the 3-wing propeller to spin.
