Apparatus 1 – Mechanical Colour Blending Machine

15_AMilne_Colour Rendering Machine_Wood_2009












This large machine was created by Andrew Milne for the Greg Hanec show ‘mechanika: the uses and benefits of mechanical problems. Though a process of accessing wooden ROM memory the machine prints a sequence of Red, Green, and Blue ink pixels on a 24ft loop of paper.

Once sufficient coverage of the paper is reached the operator may enter the projection-drive compartment and turn the large drive gear as fast as possible. A light sensitive transistor detects the presence of the black registration marks printed beside the rows of pixels and turns on a row of high power LEDs. With the paper moving at over 1000ft per minute the Red, Green and Blue pixels blend to form a series of secondary and tertiary colours.
