This week, I focused on transitioning our hardware design from a purely theoretical to a physical level, documenting the process. I finalized and submitted the parts request forms for our critical components, locking in our design choices for the motor and power systems.
I also dedicated significant time to system modeling, creating a detailed electrical diagram that outlines our power distribution network, specifically mapping out how the power supply will independently feed the Jetson Nano, the motor controller/motor, and the LED display to prevent voltage sag. Additionally, I designed a high-level block diagram to define the interfaces between our microcontrollers and peripherals. To prepare for our upcoming review, I have also begun drafting the Design Document presentation with Andrew and Kendric.
I believe we are on schedule. We are tracking well against our Gantt chart, and with the administrative work of ordering parts out of the way, we might even be slightly ahead of schedule.
Next week, as our components begin to arrive, I plan to shift focus to hardware validation. My primary goal is to test the electrical components to ensure they are functional and properly spec’d for the load before we integrate them into the mechanical assembly.
Part A:
The Hologram design prioritizes safety by rigorously mitigating the physical hazards associated with high-speed rotating machinery. The spinning LED array will be fully enclosed within a transparent, impact-resistant polycarbonate shield, ensuring that users, particularly children, cannot accidentally contact moving parts. To further prevent mechanical failure or instability, the chassis will be securely clamped to its support surface and equipped with vibration-dampening rubber feet. Regarding health, the system promotes psychological well-being by providing a mentally stimulating, interactive 3D interface that encourages cognitive engagement. Physiologically, the display is calibrated to safe brightness levels and refresh rates to minimize eye strain, and the visual fidelity is intentionally designed to be distinct from reality to prevent user disorientation. Finally, the project supports welfare by democratizing access to volumetric visualization technology; this contributes to the user’s quality of life by fulfilling needs for advanced education, communication, and entertainment.
