Hi,
I want to introduce this demo project for the Maker Faire in Hannover last weekend. The project was inspired by the work of the artist Julius Popp. We are using a transparent hose, 2 peristaltic pumps and an Arduino Uno with motor shield (both mounted in an Arduino Din rail enclosure ) to build a simple display.
The pumps pressing a pattern of water and red paraffin oil in the hose. In the end a text will be visible. For the Maker Faire we've used 2 alternating texts "Maker" and "faire" (see the picture below).
Source code and additional infos are available on our website.
