The Pink Pulsating Pancreas is a scale model of a human pancreas, designed to be entertaining and educational. It's lit from the inside with user-controlled lighting fixtures, and plays pancreas facts from built-in speakers.
Project proposal - yes, I actually got an art grant to build this!
Audio - WARNING: most of these are really strange!
Most of the work is done on a Raspberry Pi running Pure Data. An Arduino-like MCU is used to read from the fader bank and output DMX.
The MCU controls DMX lighting fixtures, and will probably handle all aspects of that, accepting a mode and some basic parameters from Pure Data. The MCU also reads from the fader bank.
This software was designed to run on a dmxfire16, but should work on any Arduino-ish (ATmega328) platform.
The DMXSerial library (v1.4.0) is required, and can be installed using the Arduino Library Manager.
The main controls are written in Pure Data. (Purr Data Version 2.5.1 (20180414-rev.8916c70) was used.)
