Project #595 Noisemaker
(IV)
OBJECTIVE: To create a sound
circuit.
Project #597
Noisemaker
(VI)
OBJECTIVE: To create a sound circuit.
Project #599
Noisemaker
(VIII)
OBJECTIVE: To create a
sound circuit.
OBJECTIVE: To create a
sound circuit.
Project #598
Noisemaker
(VII)
Modify project #598 by removing
the motor (M1). Turn on the slide
switch (S1) and press the press
switch (S2) to hear the new
sound.
Modify the sound of project #599
by replacing the whistle chip
(WC) with the meter (M2, “+”
towards right), use the LOW (or
10mA) meter setting. Turn on the
slide switch (S1) and as the
LED’s flash the meter deflects.
Project #600
Noisemaker
(IX)
OBJECTIVE: To create a
sound circuit.
Project #596
Noisemaker
(V)
Modify the sound of project #595
by adding capacitor C4 across
points A & B (+ of C4 on right).
In this project, you’ll see and hear
the output of the alarm IC (U2). Turn
on the slide switch (S1), the LED’s
(D1 & D2) flash, and the speaker
(SP) sounds as the relay (S3)
chatters. Now press the press
switch (S2) and see what happens
when you remove the relay from the
circuit.
Modify project #596 by replacing the
capacitor C4 with the motor (M1, position it
with the “+” on the left and don’t place the
fan on it). Turn on the slide switch (S1), the
LED’s flash, and the speaker (SP) sounds
as the relay (S3) chatters. Now press the
press switch (S2) removing the relay from
the circuit, providing a constant connection
to the battery (B1). The motor speeds up
and the sound from the speaker is not
distorted.

WARNING: Moving parts.
Do not touch the fan or
motor during operation.
OBJECTIVE: To create a sound circuit.
Modify project #597 replacing the speaker
(SP) with the whistle chip (WC) and
placing the fan onto the motor (M1). Turn
on the slide switch (S1) and the fan spins,
lights flash, and the relay (S3) chatters.
Now try to launch the fan by pressing the
press switch (S2) down for about five
seconds and releasing it.

WARNING: Moving parts.
Do not touch the fan or
motor during operation.
!
WARNING: Do not lean
over the motor.
