Mandalamat
Analog-hybrid mandala graphics generator
The Mandalamat is an analog controller for graphics generation producing preferably radial/circular symmetric drawings. The Mandalamat control unit combined with a modified graphic plotter (Robotron Reiss) or an oscilloscope can generate graphics like mandalas, mandala patterns, ornaments, ornamental frames and more. In combination with an oscilloscope and e.g. a beamer the Mandalamat can produce real-time animated mandalas or other graphics.
The X-axis,Y-axis (and Z-axis) outputs of the machine are generating analog voltages, which can be converted by an analog-digital converter to step-motor control impulses. These feed a XY system like a graphic plotter or an oscilloscope, making the graphics visible. The patterns can be influenced by e.g. music signals, or synchronized with rhythms and sounds made by my musical equipment. So I can create a special soundtrack and – in combination with the visuals – realize various interactions between the instruments.
