BalloonSat Light Tracker

For my Microcomputers and Electronic Instrumentation project, my team and I were tasked with designing and developing a sun tracking BalloonSat payload that was entirely self-sufficient, boasting its own power supply, sensors, microcontroller, and the capability to transmit data to a ground station. This project demanded a multidisciplinary approach, requiring proficiency in electronics, CAD design, and microcontroller programming.

I headed the design and implementation of the power and monitoring subsystems. This involved the utilization of voltage regulators, operational amplifiers, an AVR USART, microcontroller, and various resistors and capacitors, along with proper signal conditioning. My primary objectives were to ensure efficient power distribution and reliable data monitoring. By meticulously designing and testing these subsystems, I guaranteed their efficient and dependable performance through an iterative process.

In the CAD design phase, I utilized Fusion 360 to create a simple yet effective 3D model that housed all the project's subassemblies. This CAD model served as a visual representation of the design, offering a clear visualization of how each component fit together within the payload. Once the models were done, I converted it into G-code and 3D printed them.

The culmination of the project involved the integration of all subsystems into a fully functional payload. Our professor had warned us that this was the step where many prior students had failed, so we made sure to allocate plenty of time for any unforseen issues. Luckily, any problems that arose proved to be minimal, and it wasn't long until our system was functional. This payload could accurately track the sun's movement and transmit its location to a ground station. During the project presentation, we shared the intricate design decisions and challenges faced during each subsystem's development, as well as recommendations that we had for future classes. Moreover, we provided a live demonstration of the system's capabilities, showcasing its ability to autonomously track the sun and relay data effectively.

This project exemplified my ability to navigate complex interdisciplinary tasks, merging electronic design, programming, and CAD modeling to produce a successful and innovative solution. It was a valuable experience that enriched my skill set and reinforced the importance of collaborative problem-solving.
