Our project involves creating an improved version of Eli Fieldsteel’s prototype music board. The music board consists of an array of 256 photoresistors connected via USB to a computer. The computer runs a program written in the Supercollider programming language to collect and interpret data from the music board. Each photoresistor detects the intensity of light shining on it. When a drop in light intensity on a photoresistor is detected, the computer plays a note. The music board is capable of playing any combination of notes simultaneously. The improved music board will feature modular photoresistor boards and execute internal component failure checks. 256 photoresistors will be placed on 16 identical PCBs with 16 photoresistors on each board. If a photoresistor fails, a single PCB can be replaced easily without affecting the rest of the music board. To add to Eli’s original design, we will also implement: A 16x16 LED display board that will mirror the hand motions to provide a matching visual for demonstration purposes. An algorithm to smooth the data to account for effects of inconsistent light sources including interference from spotlights and low light environments. A user interface to switch between multiple instrument sounds and adjust board characteristics (pitch, volume, sensitivity, calibration) Additional Ideas: Create a generic design that can use different types of sensors (touch sensors, flex sensors, distance sensors, color sensors) Design a small, hand held, self contained version with battery power |
