“How to make a unique display from a transparent hose and an Arduino UNO.
This was a demo project for the Maker Faire Hannover 2016. 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 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.
The reservoir was an old vessel for instant tee. Paraffin oil is easier as water and will swim on the top. You have to place 3 lead-ups to the vessel with different length of hose inside:
- to the bottom for the water pump
- to the middle for the paraffin pump
- to the top for the reflow”
