GOALS

I want to make a hat, in which, you can play the accompaniment, a melody, and rhythm of a piece all simultaneously. Previously, my hat could just make random sounds, using 4 FSR's.

Weeks 1, 2, & 3

In my first few weeks, I re-wired my original lay-out for the Whacky Hat and cleaned up the connections I had for my FSR's. I struggled with getting my teensy to work, and finally got signal at the end of these weeks (after trying 5 different fried teensys!)

Weeks 4 & 5

Originally, my FSR's were assigned various oscillator-types and programmed to simply output random pitches depending on the force enacted on the sensor. This made cool sounds, but was not quite "musical." To make my hat more musical and playable as an instrument, I worked during these weeks on figuring out how to have my FSR's correspond to specific chords. At the end of Week 5, I successfully had the FSRs correspond to I, VI, IV, and V chords. These will act as the accompaniment for my piece.

Weeks 6, 7, & 8

During these weeks, I focused on the melodic component of my hat. I have been working with a 200mm linear potentiometer to make a continuous sensor that corresponds to two octaves of notes. I have gotten signal with the potentiometer, but am still working on getting it mapped to two octaves and usable as a lead component of the instrument.

Additionally, I will be using a piezo in my shoe (mapped to a snare sample) to induce a sense of rhythm whenever I tap my foot. I have started mapping this, and found the snare sample I will be using.

Week 9

In week 9, I got the linear potentiometer mapped to a continuous octave (from C3 to C4). I ran into a few issues with the potentiometer cutting out the signal from the other sensors when activated, but spent time troubleshooting this issue so that all the sensors can work at the same time.

Week 10

In week 10, I connected the piezo to the hat and figured out how to connect my snare sample to the piezo.
