1/7/2026 8:25 PM - I just finished the CAD of the raspcamX

The first step of this project was CAD designing, which was essential for planning and visualizing the entire system before physical assembly. Using computer-aided design software, a detailed 3D model of the enclosure and internal layout was developed. Nearly 10 hours were spent carefully aligning the Raspberry Pi 4, HQ Camera, Mini UPS, and USB storage, while also thinking about portability, compactness, and ease of handling. Special attention was given to cable routing, ventilation, and accessibility of ports to ensure smooth operation. This process helped in identifying space constraints and design issues at an early stage, thereby reducing errors during the actual build. By finalizing the design digitally, unnecessary rework was avoided, saving time, materials, and cost, and resulting in a practical and portable final design.

After completing the initial CAD design, the next stage involved aligning and verifying the CAD models of different components, including the Raspberry Pi 4, Sony IMX477 sensor (HQ Camera), interchangeable lens, mounting screws, photo capture button switch, and the display module. Each component was carefully positioned to ensure proper fit, correct alignment, and functional accessibility. Special attention was given to aligning the camera sensor with the lens mount to maintain accurate focus and image quality. The placement of screws was checked to provide structural strength without interfering with internal electronics. The photo capture button was positioned for easy user access, while the display was aligned for clear visibility during operation. This step ensured mechanical compatibility between all parts and confirmed that the final assembly would be stable, functional, and user-friendly.

After finalizing the CAD design and component alignment, the next step was wiring the entire system. All electrical connections were made using standard jumper wires, USB cables, and ribbon cables, eliminating the need for a custom PCB. The Raspberry Pi 4 was powered through a Mini UPS using a USB power connection to ensure stable power supply and safe shutdown. The Sony IMX477 HQ Camera was connected to the Raspberry Pi using a CSI ribbon cable, enabling high-speed image and video data transfer. The display module and photo capture button switch were connected to the appropriate GPIO pins for user interaction. Care was taken to route the wires neatly to avoid interference, ensure proper airflow, and make troubleshooting easier. This wiring approach made the system modular, cost-effective, and easy to modify or repair if required.

1/7/2026 8:36 PM - The finale : Checkout , BOM and submission

The final stage of the project involved complete system checkout, preparation of the Bill of Materials (BOM), and final submission. During the checkout process, all electrical connections, camera functions, power stability, display output, and control buttons were thoroughly tested to ensure reliable operation. After successful testing, a detailed BOM was prepared, listing all components used in the project along with their specifications. Component sourcing was one of the most time-consuming stages, as significant effort was spent in identifying affordable yet reliable components without compromising performance or quality. To document and share the project, a GitHub repository was created containing the project description, wiring details, and software references, enabling transparency and future improvements. The project was then organized, documented, and submitted successfully, completing the development cycle in a systematic and professional manner.
