The motor was rather noisy until we figured out a position to squeeze it (near the top) that makes it virtually silent. Then, we iterated, and attached a potentiometer (fader) to control the voltage. This successfully created a moving pitch that sounded very siren-like!

The 4 faders could possibly control ball valves to partially open/close the air hoses as opposed to flow, which we do not have a good grasp of how to control (cheaply; a regulator might work). The buttons could also serve as the valve control, or could power on/off the air supply.

MVP

  • For a minimum viable product, I need to accomplish my goal of developing multi-functional faders, faders which function as encoders and buttons. So, I need at least a simple casing to house the electronics, which would at minimum be four complex faders.


The Plan

  • I want to have, by the final deadline, a clean and polished product with four multi-functional components, four programmable single buttons, and a tactile controller for directional interaction, all sending MIDI messages to my computer via USB.


Unlimited Time + Resources Vision

  • With unlimited time and resources, I would want to expand on my current idea and revisit my original concepts for a modular MIDI controller, with multiple separate modules of faders, potentiometers, button banks, tactile controllers or joysticks, and piano keys.
