The document summarizes a student project to create a highly visible power meter that displays battery status and power generated by volunteers. The meter must consume low power, meet the client's needs, and be durable, portable, and reproducible at a low cost. The final design uses an Arduino microcontroller with LED lights and circuit boards housed in an aluminum frame on a mobile base. It came in under budget through the use of reclaimed materials.
