Use the preceding circuit. Using the fan as a guide, draw a circle on a piece of cardboard
or paper. Cut the circle out with scissors and tape it to the fan blade so it can be easily
removed later. Obtain some thin and thick marking pens to use as drawing tools.
Spin the paper by pressing and holding the press switch (S2) down. Gently press the
marker on the paper to form rings. To make spiral drawings, release the press switch and
as the motor approaches a slow speed, move the marker from the inside outward quickly.
Change the colors often and avoid using too much black to get hypnotic effects. Another
method is to make colorful shapes on the disc then spin the disc and watch them blend
into each other.
Spin Draw is an old toy that your parents may have played with when they were young.
