The Power Wall Project is a custom-piece of power equipment designed to provide an electrical source, on-demand when the equipment is away from standard electrical outlet. The team of Islay Clare-Kellet (Power) and Katharyn Taylor (Telecom) worked closely together to design, procure materials and components, create detailed design, build, test, commission, and document the project. The overall cost for the project materials went over budget of $800 by $200 due to replacement of equipment during the commissioning phase. During the seven phases of the project plan, the team experienced accomplishments, like completing the working version of the Power Wall. The first prototype the current Power Wall performs well and provides three voltage levels and can be started and stopped simply with the two push buttons and latching relays. The physical unit is can easily be used a camping power supply and it isn’t the typical and polluting generator one can find at their local Canadian Tire story. The finished unit is rugged and can be rolled over rough terrain. It will prove to be an excellent camping companion when needing to power phones, coffee makers or lights. The team also experienced a number of challenges on the technical and human resource sides. On the technical side, the team learned the timing and requirements to carry out in-depth research on limits, capabilities and common issues related to the equipment and processes associated with the design and production of the equipment. Should we have conducted more research, we would have discovered that there was a common issue with turning the analog signal from AM712 to a digital sensor. We also discovered, the hard way, that giving too much voltage to the input pins would kill the pi. In the end, though we were able to construct a working prototype of the Power Wall, with power monitoring capabilities, we learned important lessons on being accountable to the Project Plan deadlines, on team communication and on personal commitment to the project objectives. While these human resource challenges almost seemed insurmountable during the project implementation, it was our perseverance and our team commitment that kept us motivated and focused on the end goal. We are proud of our work and thankful for the experience.
