9. Invention, Intellectual Property, and Income

assignment Develop a plan for dissemination of your final project Complete your final project, tracking your progress: what tasks have been completed, and what tasks remain? what’s working? what’s not? what questions need to be resolved? what will happen when? what have you learned?

Dissemination Strategy

The project will be disseminated through several channels to maximize its impact and accessibility.

1. Fab Academy Documentation

The complete design process, source files, fabrication methods, electronics, programming, and testing results will be documented on my Fab Academy website.

This documentation will allow other students, makers, and researchers to replicate and improve the system.

2. Open-Source Design Files

The following files will be shared openly:

  • CAD designs
  • PCB designs
  • KiCad files
  • Source code
  • Wiring diagrams
  • Assembly guides
  • System integration documentation

This supports knowledge sharing and community-driven improvements.

3. Community Demonstrations

The system will be demonstrated to local communities, schools, and organizations interested in water purification technologies.

The demonstrations will focus on:

  • Water quality monitoring
  • Solar-powered operation
  • Low-cost fabrication methods
  • Community maintenance and operation

4. Research and Collaboration

The project will continue collaboration with:

  • Fab Academy
  • Skylab Workshop
  • Fablab Winam
  • Toyota
  • BioClub Tokyo

These collaborations will support future testing and validation.

5. Future Commercialization

  • MQTT communication is functioning.
  • OLED display successfully displays system data.
  • Modular architecture has been defined.
  • Water treatment process flow has been established.

What Is Not Yet Working?

  • Final integrated PCB has not yet been manufactured.
  • Full system integration remains incomplete.
  • Automated valve control has not been fully tested under real operating conditions.
  • Photocatalyst chamber performance requires validation.

Questions That Need To Be Resolved

  1. Power source and pcb board
  2. How to take a final vedio for the system with dirty water and system yet it takes time to get clean water
  3. System Design which shapes etc…
  4. What is the long-term maintenance requirement of the filtration materials?
  5. What is the most cost-effective design for large-scale deployment?

Timeline to Completion

Week 3

  • Integrate physical modules
  • Complete wiring and plumbing

Week 4

  • Perform full system testing
  • Validate sensor operation

Week 5

  • Final documentation
  • Final presentation preparation

What I Have Learned

This project has significantly improved my understanding of:

  • Electronics design
  • PCB development using KiCad
  • MQTT communication
  • Water treatment technologies
  • System integration
  • Open-source product development

Most importantly, I learned how to integrate multiple disciplines into a single functional system that addresses a real-world problem affecting my family and community.

The project demonstrates how digital fabrication, electronics, programming, and engineering can be combined to create practical solutions for safe drinking water access.
