Week 20: Final Project Presentation
Project: OrquiWall Smart System
Presentation Slide and Video
The final presentation material summarizes the OrquiWall Smart Irrigation System for orchids, including the problem, technologies, system architecture, fabrication processes, and the operating logic of the prototype.
Final Project Overview
OrquiWall Smart System is a smart orchid care module that integrates a digitally fabricated wall frame, 3D printed plant and water components, a custom PCB, sensing, display, cable management, and a motorized mechanical system. The prototype demonstrates the relationship between digital fabrication and biophilic design.
What I Made
| Subsystem | Fabricated / Integrated Elements |
|---|---|
| Structure | MDF sliced wall frame generated with Slicer for Fusion 360 and cut as DXF pieces. |
| Plant interface | 3D printed orchid pot, reservoir, planter supports, and final presentation with a real orchid. |
| Electronics | Custom KiCad PCB fabricated with fiber laser, ESP32 XIAO C3, A4988, sensor, LCD, switches, and wiring case. |
| Mechanical design | Stepper motor, lead screw, bearing, guide rods, printed supports, and movement tests. |
| System integration | Final assembly combining electronics, structure, reservoir, pot, wiring, LCD, and final irrigation test. |
Final Demonstration
The final test validates the assembled prototype as a complete system. The orchid is installed in the printed pot, the reservoir is positioned in the structure, the LCD interface is visible, and water is introduced to demonstrate the irrigation concept.
Fab Academy Requirements Covered
| Requirement | Evidence in Final Project |
|---|---|
| 2D and 3D design | Fusion 360 models, KiCad PCB design, Slicer framework, and printed parts. |
| Additive fabrication | PLA pot, reservoir, motor supports, bearing holders, wiring case, LCD support. |
| Subtractive fabrication | Laser-cut MDF frame and fiber-laser fabricated PCB. |
| Electronics design and production | Custom PCB schematic, layout, laser engraving, drilling, soldering, and testing. |
| Embedded programming | Irrigation and movement code for ESP32 XIAO C3. |
| Input and output devices | Humidity sensor, limit switches, LCD, A4988 driver, and stepper motor. |
| Mechanical design | Lead screw mechanism, motor supports, bearing alignment, and final assembly. |
| System integration | All fabricated and electronic components assembled into a final prototype. |
Build Process Summary
Final Result and Evaluation
The final prototype demonstrates that the fabricated structure, electronics, mechanical movement, plant pot, reservoir, and wiring can be integrated into one object. The project successfully communicates a smart biophilic module and validates the main technical layers required for a future improved version.
| Evaluation Area | Result |
|---|---|
| Visual presentation | The organic MDF frame and orchid create the intended biophilic aesthetic. |
| Mechanical integration | Stepper motor, lead screw, bearing, and supports were assembled and tested. |
| Electronic integration | PCB, LCD, driver, sensor wiring, and case were connected and organized. |
| Irrigation demonstration | Water reservoir and orchid pot were tested in the final prototype. |
| Documentation | Process, files, images, video, and final integration are documented online. |
