Douglas Irving Repetto’s amazing painting machine! – “Giant Painting Machine (Milano) is a simple electro-mechanical system built largely from found parts and scrap materials. It paints complex and dynamic abstract images on four transparent walls by tracing continuous, cycling paths across large sheets of clear mylar. Because GPM is a wiggly mechanical device, the nature of its brush strokes is constantly changing, and its conceptually smooth, arcing lines are full of smudges, drips, and wobbles.
Simple switches and a DC motor controller guide the paintbrush across the canvas. The path of the brush is determined by the relationship of the dimensions of the canvas to the speeds of the motors. The speeds of the motors constantly ramp up and down, resulting in curved, rather than straight, lines.
The brushes are filled with acrylic inks in various colors. Mixing decisions are made on the fly, with each wall focused on a certain color.” – [via] Link.
There will be a smaller version of this at the Maker Faire! Woo!
