33. Bicycle Powered Generator Neeraj Annachhatre (Project Leader) Soujanya Bulagannawar Siddharth Prashant

34. Objective The main objective of this project is to educate the students of the Happy Hollow Elementary School about the idea of conversion of energy. Specifically, how the conversion from mechanical energy to electrical energy can power electrical appliances.

35. Description of Project The generator works by a person pedaling the bicycle, thus rotating its rear wheel. A dynamo hub is connected to the rear wheel. The dynamo outputs electrical voltage by converting the mechanical energy from the rear wheel into electrical energy. This voltage is used to power electrical appliances such as a light bulb and a radio.

36. Design Connect the dynamo (generator) to the rear wheel of the bike. The dynamo’s output will generate AC current, which is to be converted to DC in order to run the light bulb and the radio. This is achieved using a rectifier circuit, which is constructed using diodes, resistors and a capacitor.

37. Design The output of the rectifier is then sent to the inputs of the television, radio and light bulbs. Testing of the dynamo is done using an oscilloscope. The output of the rectifier can also be tested using this. The dynamo gave an output voltage of about 6 Volts AC. Rectifier gave an output of about 4-5 Volts DC.

38. Design

39. Educational Material We created a user manual which explains how the bike generator works as well as a brief description on conversion of energy and other educational values of the project. The manual will also contain the project’s safety requirements. A poster has been designed. It briefly describes educational topics such as the conversion of mechanical energy to electrical energy and curren. .
