Build the circuit as shown. Place the black cable holder on the color
LED (D8), then place the fiber optic cable into the holder as far as it will
go. For best performance the fiber optic cable should stand straight up
in the holder, without bending it. Leave the other end of the cable free.
Turn on the switch (S1), and look into the loose end of the fiber optic
cable. Flex the cable into loops but don’t dent it. Take the circuit into a
dark room and see how the cable looks.
You can use the clear cable holder on the color LED instead of the black
holder.
Build the circuit as shown. Place the clear cable holder on the
color LED (D8) and the black cable holder on the
phototransistor (Q4), then place the fiber optic cable into the
holders as far as it will go. For best performance the fiber optic
cable should stand straight up in the holders, without bending
them.
Turn on the switch (S1). The color LED (D8) turns on and off
repeatedly as it changes colors. This produces interesting
effects when connected to the speaker circuit through the fiber
optic cable.
