Dissemination Plan¶
I want to share my final project openly with the global maker and Fab Lab community. All my design files, documentation, and source code will be available on my Fab Academy page and GitHub repository. I may also share it on platforms like Hackster.io and Instructables to reach a wider audience.
My main goal is to support other makers, educators, students, and anyone interested in building or improving similar systems. I hope that by making it open, people can learn from it, remix it, and make it even better.

Invention and Income¶
My invention is a compact, open-source guitar tuner system that uses a piezoelectric sensor to detect string vibrations, amplifies the signal, and processes the frequency data using a Raspberry Pi Pico. While guitar tuners exist, I designed and built this version from scratch, combining analog amplification and digital signal processing in a way that’s tailored to makers and Fab Lab users.
What makes this project unique is its simplicity, reproducibility, and educational value — it demonstrates key principles in electronics, sound analysis, and embedded programming. It’s an accessible tool for learning about sensors, analog signal handling, and FFT-based frequency detection, and can serve as a base for more advanced audio or instrument-related projects.
At this moment, I am not planning to commercialize the project. The main intention behind creating it was to explore and learn through hands-on making, and to contribute something useful and educational to the open-source hardware and maker communities.
However, I’m open to the idea of using the project in workshops or educational environments, and I encourage others to build on this work and adapt it to their needs — as long as they follow the license terms.
Future Plans¶
I am thinking about continuing this project, and making device that also tunes guitar automatically using motors an PID control. Also it needs to be more ergonomic.
Conclusion¶
I believe that open sharing accelerates innovation and learning. By keeping my project open and accessible, I hope it will benefit others and grow beyond what I’ve built during the Fab Academy.
