Elenco LIGHT - Manual (Page 23)

-22-
Build the circuit as shown. Place either the glow fan or the light fan on
the motor (M1) shaft, so that it is stable on the little black piece. Place
the clear fiber optic holder on the color LED (D8) and the black fiber optic
holder on the phototransistor (Q4), then insert the fiber optic cable
between them, but don’t let it lay close to the fan on the motor. For best
performance the fiber optic cable should stand straight up in the holders,
without bending them. Connect a music device to the color organ (U22)
as shown, and start music on it. For best effects, place one of the LED
attachments over the light on the color organ.
Turn on slide switch (S1). Adjust the lever on the adjustable resistor (RV)
and the volume control on your music device for best sound and light
effects.
Push the press switch (S2) until the motor reaches full speed, then
release it. The fan will rise into the air like a flying saucer. Be careful not
to look down on the fan when it is spinning. If desired, connect the light
fan blade to the charger for a while to charge it, then place it on the motor
to spin or launch it.
“Playing the Color Organ”: turn off or disconnect your music device. Wet
your fingers, and touch them between the point marked “X”, and “R”, “G”,
or “B” in the drawing.
The infrared detector (U24) and 100k
Ω
resistor (R5) are only used to
support the other components.
!
WARNING: Moving parts.
Do not touch the fan or
motor during operation. Do
not lean over the motor.
