16. Applications and implications

this week i will cover everythin i need for my final project, an electric guitar with neopixels that turn on with the music

BOM (bill of material)

HAS IT BEEN DONE BEFORE?

Yes, the concept of guitars with integrated lights is not entirely new. Throughout history, many guitars have been customized with various visual enhancements, including lighting effects. A notable example close to home is from Fablab Puebla, where Birkir Þór, documented in his Fablab website in 2017, achieved impressive results with a similar project. While these examples exist, what sets my project apart is the integration of NeoPixels that illuminate dynamically in sync with the guitar's music during play, a feature I haven't found in previous designs.

WHAT WILL IT DO?

The concept is to create a custom electric guitar that not only delivers exceptional sound but also captivates visually with synchronized lighting effects. Embedded NeoPixels strategically positioned around the guitar's body will dynamically illuminate in sync with the music being played. This integration aims to enhance the performance experience by visually accentuating the rhythm and intensity of the music, creating a dynamic interplay of sound and light that engages both the performer and the audience.

WHAT AM I DESIGNING?

I am embarking on designing a bespoke electric guitar that draws inspiration from the classic stratocaster design while incorporating unique modifications tailored to enhance both functionality and aesthetics. The custom design includes reimagining the guitar's headstock for a distinctive look, adjusting the arm angle to minimize fret buzz issues common in similar designs, extending the scale length for enhanced playability, specifying a precise number of frets to suit musical styles, and refining the body dimensions for improved ergonomics and comfort during extended playing sessions.

WHERE ARE THE MATERIALS COMING FROM?

All materials required for this ambitious project will be sourced primarily from Fablab Puebla, a renowned hub for innovation and fabrication. The guitar's body will be crafted from select woods available at the lab, ensuring both quality and sustainability. Essential guitar components, including electronics and hardware, will be procured locally through Fablab Puebla's extensive network of suppliers. Additionally, specialized components such as NeoPixels for the lighting system will be provided by the lab. However, certain components like the microcontroller will be sourced separately to meet specific project requirements and performance criteria.

PROCESS

  • Designing the body, neck, and fretboard of the guitar for optimal performance and aesthetics.
  • Utilizing CNC machining to precision-cut the guitar components for accurate assembly.
  • 3D designing and printing of components such as the nut, pickup supports, and electronics lid to ensure functionality and integration.
  • Testing the acoustic properties and sound quality of the guitar to ensure clarity and tonal accuracy.
  • Designing and fabricating a custom PCB that integrates NeoPixels for synchronized lighting effects and a sound sensor for responsive functionality.
  • CNC cutting of the PCB and meticulous soldering of components to ensure reliable performance.
  • Programming the PCB to control NeoPixels based on guitar input, ensuring seamless synchronization with musical cues.
  • Final assembly of the fully functional guitar, integrating the PCB and NeoPixels to deliver a cohesive and dynamic visual and auditory experience.

PROBLEMS

  • In case the angle of the guitar arm is too low, measures will be taken to prevent fret buzz, possibly adjusting the fretboard alignment or string height.
  • Ensuring accurate sound detection by the microphone amidst ambient noise.
  • Evaluating any impact of NeoPixel lighting on guitar sound quality.
  • Determining whether to power the LEDs from the guitar's internal power or an external source.

HOW WILL IT BE EVALUATED?

  • Ensuring the guitar produces clear and high-quality sound.
  • Verifying the ability to control volume and tone effectively through integrated potentiometers.
  • Testing the NeoPixels to ensure they illuminate accurately and in sync with the guitar's music, enhancing the visual experience without compromising sound quality.
