Scaffolding: NIME - Da Funk Box

 

 For my NIME, I decided to create a tribute to one of my all-time favorite musical acts, Daft Punk, who sadly broke up earlier this year. As a tribute, the purpose of the box is to play one of their old classics, Da Funk.

My conceptual model for the NIME was to have different parts of the song playing so that users can either recreate the song in it's entirety, or remix it to their liking. Their are three different inputs: the left button plays the main melody of the song, the right button plays the secondary melody that plays in the middle of the song, and the potentiometer controls the position of the lit neopixel on the CPE, so that users can emulate the same kind of light shows that can be seen from Daft Punk concerts. How it does this is that the potentiometer is mapped nearly 1:1 to the number of neopixels on the board. When the user moves the potentiometer, they change which neopixel is lit. A servo inside the box acts as an acoustic backing beat to the song that stops moving when either of the buttons are pressed.

To signify what each of the inputs do, I added a description of their inputs on the box, stating that the left button will play the main melody and the right button will play the secondary melody. The potentiometer was simple labled as "Light Show" to show that it can be used to make the neopixels on the CPE dance.

I believe this to be a quality tribute, but do you know of a better way that this song, or any song, can be emulated better with a NIME?
