Build the circuit as shown. Note that there is a 3-snap wire
under the NPN transistor (Q2) that is partially hidden, and
a 5-snap wire under the disco motor (DM), partially hidden.
Turn on the slide switch (S1). The display on the LED-MC
(U29) displays “00”, the programmable fan (M8) spins &
lights, and the disco motor (DM) spins & lights. Press the
A button on the selector (S8) once to make the display
show “01”, then press the B button on the selector to start.
Every few seconds one or more of the following will
happen, randomly changing: the yellow LED (D10) lights,
the programmable fan spins & lights, the disco motor spins
& lights, the speaker plays a tune, and the U29 LED
display shows a random pattern.
Use the preceding circuit. Turn on the slide switch (S1); the display on
the LED-MC (U29) shows “00”. Press the A button on the selector (S8)
two or three times to increase the ones digit on the display. When the
display shows “02” or “03”, press the B button on the selector to start.
The circuit works the same, except that it changes faster. “03” is faster
than “02”.

WARNING: Moving parts. Do not
touch the fan while it is spinning.
