Solar reflector¶
overview¶
Our task in this project involves developing a device capable of redirecting sunlight from sunrise to sunset towards a specific location. The purpose of this project is to assist small plants, such as bushes, which are overshadowed by larger plants like palm trees, preventing their growth in certain areas. Additionally, this device could also provide illumination for houses using sunlight.

component¶
There are three main components that I need to create..
1. Mirror Stand¶
I need to design a body that is capable of supporting a mirror and ensuring its movement along two axes, namely the X and Y axes. It is a standard practice to iterate through the process of drawing, printing, and testing multiple times until success is achieved. By continuously refining the design, I can ensure that the body effectively accommodates the mirror and facilitates smooth movement in both directions. This iterative approach allows for adjustments and improvements, leading to a successful outcome
After realizing that a key for the rotating system was omitted during the printing process, we made the necessary adjustments by drilling and modifying the model. This enabled us to successfully resolve the issue and ultimately achieve the desired outcome, resulting in the final version of the project.
So, I incorporated the necessary change into the 3D model as well ;)

2. LDR’s Stand¶
I need to design a compact body capable of accommodating four Light Dependent Resistors (LDRs), which are components that change resistance based on light intensity. To ensure the LDRs are exposed perpendicularly to sunlight, I will incorporate partitions within the body. Fortunately, I found a helpful example on the web that aligns with my requirements, which served as a reference for my drawing.
This attempt marks the initial step of a long journey ahead T_T
After realizing that the blue micro servo motor was unable to handle the weight of the LDRs with partitions, we decided to redesign the setup. We opted for a black corona servo motor instead, as it had the necessary strength to support the LDRs. Although the size of the new servo motor differed slightly, even minor changes can make a significant impact on the overall performance and functionality of the design.
Throughout the design process, we made numerous attempts, but the most significant breakthrough occurred in the final iteration. We addressed critical issues by adding support to the arms, resizing them appropriately, and incorporating a horn to effectively handle the motor tip. These modifications successfully alleviated several challenges and provided solutions, relieving us of significant concerns and streamlining the overall design.

3. body¶
After completing the designs for the mirror stand and LDRs body separately, the next step involved connecting them together. Two options were considered for this integration, which can be viewed on Ali AlNasser’s website. Initially, AlNasser designed the connection using cardboard, and later I made some modifications and created a 3D drawing for a more refined version. The collaboration between AlNasser’s initial design and my subsequent enhancements resulted in an improved and visually appealing connection between the mirror stand and LDRs body.
We proceeded to create holes for the wires to ensure proper connectivity between the components. Additionally, we added another floor to accommodate the motor, enabling it to handle the motion of the mirror. These modifications were crucial in ensuring the functionality and seamless integration of the various elements within the design. By incorporating these enhancements, we established a well-organized and efficient system for managing the wires and facilitating the motor’s role in controlling the mirror’s movement.

Gears & bearings¶
To ensure the smooth operation of the motor without any torque-related issues, we decided to incorporate gears and bearings, specifically for the mirror mechanism. By introducing gears and bearings into the design, we aimed to distribute the torque evenly and minimize any potential strain on the motor. This addition helps to enhance the overall stability and efficiency of the motor’s functionality, allowing it to operate seamlessly and without encountering any problems related to torque.
