Using Korg's KPE1 Kaoss Entrancer pad as a starting point of this project I intended to make an item of hardware that offers much of the same functionality specifically tailored for live video editing (whereas the Entrancer is essentially an audio MIDI controller with a few video editing capabilities.)
In this diagram here we can see the signal being routed from the Arduino and microphone input, through as series of scales to upscale the signal to a degree that is useful for Pure Data and into a series of video filters used to distort the output.
The casing for the hardware build was created out of 6mm black acrylic lasercut using Victoria University's laser cutting facilities. In hindsight 6mm acrylic is much too thick and creates MANY issues when finding components as most of the components I required have a thread of around 4-6mm making is hard to attach to the casing.
