Did you know that you can charge your phone while cycling? Now The wrench will show us how to make a simple electric generator that can generate enough energy to maintain the charge of your phone while riding a bicycle.
Watch a video of a homemade electric generator:
In order to make such an electric generator we need:
1. Unnecessary Car Charging for Phone
2. OTG cord or usb connector
3. Two small wooden bars
4. 12v electric motor
5. Plastic ties
Let's get started!
1. Take a block and glue the motor to it. Then we drill holes and fasten the motor to the couplers.
2. We disassemble unnecessary car charging. We cut off the excess wires, and solder our wires in place of the outgoing wires. Unforgettable chip solder to the motor. You need to solder the wires from the connector that was inserted into the cigarette lighter. We solder the usb connector to the output of the microcircuit. We will insert a cord into this connector, through which the phone will be charged.
3. Take another block and drill 3 holes.
4. We attach this entire structure to bike near the wheel. The shaft of our generator (rubber wheel) should touch the bicycle wheel. We try to pedal. If the phone does not charge, then you did something wrong. Be careful! When testing the device for the first time, measure the voltage on the usb connector! It should not exceed 5V.
Pedal and charge your smartphone!
