Goal: Design and fabricate a graphic equalizer with 10 bands of frequency modulation.

Scope: The equalizer will be designed from the ground up, including both mechanical and electrical components. A custom PCB will be designed to allow potentiometers to adjust the signal coming from the audio source.

Constraints:

• The enclosure will be 3D printed to keep costs low for prototyping purposes.

• The PCB will be designed using KiCad, an open source software. This will be the largest hurdle since I have not yet designed a PCB in my career.

• Use off-the-shelf electrical components to receive and modulate the audio signal.

I recently began putting together a home audio system for listening to music and watching movies. I wanted a method to adjust certain audio frequencies depending on the media I was listening to. After some research, I began working on a 10-band graphic equalizer to install into my system.

I have completed a prototype design of the enclosure and necessary switches and connectors. I am currently working on learning about the KiCad software so that I can design the PCB and have it manufactured.
