We have created a 3D printed grandfather clock to convert its mechanical energy into electrical energy to power LEDs. We chose this project because it involves physics and can help people in need of a light source.
We are using a low voltage dynamo to generate electricity. Adding neodymium magnets into the clock, will also help generate the electricity intended. After connecting the LED's to it, we crank the dynamo using the running clock to convert mechanical energy into electrical energy.
