Laser Projection with Arduino
This device can project attractive laser beam patterns on virtually any desired surface. The basic idea is to manipulate the path of a laser beam from a source such as a laser pointer. The beam is deflected by a small mirror fitted to the end of a motor shaft. The mirror is not perfectly perpendicular to the axis of the shaft, so the originally linear beam path is converted into a cone.
