Project #74
+
You are getting sleepy...
Build the circuit as shown (the same as the preceding project). 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.
Assembly
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.
