This high voltage source, capable of delivering up to 4 kV with a power output of 10 W, was developed at the University of Plymouth, UK, as part of a DARPA-funded project (HR001118C0125; https://www.highergov.com/contract/HR001118C0125/) investigating quantised inertia (QI). The system was integrated with a Raspberry Pi 4B, enabling automated measurements and remote control. A Python-based graphical user interface (main.py) was developed to facilitate user-friendly operation and precise control of the system.

To align with the potential application of the project in space research, the dimensions of the device were specifically tailored to meet the requirements of CubeSat platforms: https://en.wikipedia.org/wiki/CubeSat. CubeSats are standardized miniature satellites, typically measuring 10 cm × 10 cm × 10 cm per unit (1U), and are widely used for cost-effective and versatile space missions.

Quantised Inertia (QI) is a theoretical framework that proposes inertia arises from quantum interactions with the universe’s horizon, offering a new perspective on fundamental physical concepts. This project focused on supporting experimental studies of QI, with this high voltage source serving as a key tool in ensuring reliable and consistent measurements.

Developed within the University of Plymouth, this system highlights the integration of software and hardware to meet the specific demands of cutting-edge research, providing a foundation for further exploration in the field.
