MEGN 301 Mechanical Integration and Design

Group project involving the creation of a portable power generator that can charge devices, display charging status, and has a flashlight for low-light conditions. My main contributions to this project were the power storage and delivery system.

The generator contained a NEMA 23 step motor which charged a series of supercapacitors. The NEMA 23 was cranked using an axle connected to a pulley so that handles on both sides could be used. The power from the motor was converted to DC using a full bridge rectifier which fed into a buck converter. The supercapacitors then powered a 5v 1a USB-C port, an arduino and screen, and a 5W LED. Below is a circuit diagram for the system.

Simulations and calculations were performed on the system to ensure that the system would work properly. The process is documented in the final report below.
