Dr. Andras (Bandi) Gschwindt, HA5WH, proudly displays Phase 3-D's Battery Charge Regulator (BCR) at the Marburg P3-D Lab. The BCR is a critical piece of Phase 3-D flight hardware that will control all the spacecraft's onboard power activity such as regulating battery charging from the solar panels. The BCR was expertly built by Bandi and his team at the Technical University of Budapest, Hungary.
