  Doornamo + rectifier circuit

Doornimo aims to utilize the every day actions of human beings (such as opening and closing a door) to produce energy. Its set up includes a motor anchored to a door frame as well as a wheel against the ground. The wheel spins the motor's spindle, producing a voltage potential difference between the motor's pins. These pins are connected to a rectifier circuit so that Doornimo generates a positive voltage both opening and closing the door. Once rectified, the voltage is then used to charge a capacitor and store the generated energy. We built this project through the use of 3D-printing as well as bread-boarding for the electronics. We were challenged by the mechanics of this design. It was difficult to integrate different aspects of our design into one functioning object. Despite the challenges, we're proud to have made a stable proof of concept, capturing waveforms of the energy Doornamo has generated. Future iterations of Doornamo would include a more simplistic design, reducing the wheel count from three to one. We would also want to look into ways to improve Doornamo's efficiency, to produce more substantial amounts of energy.
