First Update (4/13)

Friday Update #1

Project and Motivation

For my final project, I’m going to be building a reprogrammable guitar effects pedal. I will be closely following a Sparkfun tutorial to build the hardware. The pedal will use a teensy to control the effects, so that is where the project will get creative. There are a number of pre-made effects already online, but I want to build my own custom phaser or flanger. This will be the more time-intensive part of the process, but perhaps the more fulfilling.

This project’s motivation comes from a love of guitar and guitar effects. My own pedal board already has a number of effects (chorus, overdrive, delay), but to complete my sound, I want to add some new effects. Because the pedal is reprogrammable, if I want a different effect for a different recording, I can take the time to make the new effect (albeit not on stage, that would be kind of time-consuming). I really enjoyed playing with Max for our last lab, so I’m excited to mess around with the effects and sounds that it can produce.

Background Research

Building a guitar pedal is pretty difficult to do from scratch. It involves complex circuitry and design, and a in-depth knowledge of sound and effects. Luckily, there is a tutorial online for building the pedal I want to build: https://learn.sparkfun.com/tutorials/pro…. Like I said, I will follow this tutorial to build the hardware.

Along with the tutorial are a number of pre-made effects: https://github.com/sparkfun/Proto_Pedal/tree/master/projects/teensy-based/sketches. Using these as a starting point, I will build and change them as best I can to create the effects I want.

    This is a great idea! What kind of effects are you interested in, once you’ve built the pedal? I recommend The Strokes for inspiration.

    I think a phasor/flanger would be cool! I’m also looking into wah or delay.

    This seems super cool; would you be reprogramming between uses with premade programs or would there be a way to get multiple effects in one show? I.E. do you have your computer with you when you play?

    Would have to be done between uses. Theoretically, each of the five dials could have a different use and possibly have different effects,but I’m not positive of that.
