Final Product

Our final design...

We bought a tire and used the chain system in a cycle to create a peddle system to rotate the wheel. The wheel is then connected to a dynamo directly. When the wheel moves the magnet in the dynamo rotates    creating electricity which is then picked up by copper wire and sent to a switch. The switch basically broke and connected the electricity circuit hence it could switch off or switch onn the bulb that was powered by the dynamo. The switch was then connected to the bulb which received power from the dynamo. To hold all of this we made a stand by welding metal.

The paddle system -

The dynamo directly connected to the wheel and with copper wire coming out at the end which supplies power to the bulb-

The copper wire connecting the switch and the bulb-

We added a NXT motor to show that this device could be stopped and started automatically. So what we basically did was that a motor was placed next to the switch. A timer was set for the motor to go off and on, so when the timer went off the motor started clockwise rotation and switched of the motor. The benefit of this was that if this device was used in the theatre industry and there was a stage show going on and you wanted all the lights to go off at a particular time the motor would switch them off.
