Project 66
2-Speed Mirror Ball
Build the circuit,
placing the mirror
ball on the orange
motor (M9) and
the wind fan on
the clear motor
(M4). Turn on the
slide switch (S1);
both the mirror
ball and the fan
spin. Push the
press switch (S2)
to speed up the
mirror ball and
shut off the fan.
Use the preceding circuit but swap the locations of the
orange and clear motors, to match the circuit shown
here. Turn on the slide switch (S1); both the mirror ball
and the fan spin. Push the press switch (S2) to speed
up the fan and stop the mirror ball.

2-Speed Fan
Project 68
Musical Mirror Ball
Build the circuit, placing
the mirror ball on the
orange motor (M9). Turn
on the slide switch (S1). A
melody plays and the
mirror ball spins. The
speed of the mirror ball
varies as the melody
changes. The sound may
be abnormal, especially if
your batteries are weak.
Project 69 Musical Fan
Use the preceding circuit, but replace the orange
motor (M9) and mirror ball with the clear motor (M4)
and wind fan. The fan speed may vary a little as the
melody changes, and the sound may be abnormal.

The clear motor briefly stops
or reduces speed as the
melody changes, but may
be spinning too fast for the
effects to be easily seen.
