Use the preceding circuit, but
swap the locations of the
speaker (SP2) and color
LED (D8). Now the color
LED is at full brightness
during playback, and RV
adjusts the sound volume.
Set the 500kW adjustable resistor (RV3) to
mid-range. Turn on both slide switches (S1),
you hear a beep signaling that you may begin
recording. Talk into the microphone until you
hear a beep (signaling that recording time is
over), then turn off the left slide switch to exit
recording mode. Push the press switch (S2)
to play back the recording, and turn the knob
on RV3 to change the playback speed. You
can play your recording faster or slower by
changing the setting on RV3.
Move the lever on the adjustable resistor
(RV) to change the brightness of the color
LED (LED) during playback. Most of RV’s
range will give little or no LED brightness.
Recording time is 6 seconds at normal speed,
but this can be changed depending on the
setting of RV3 when you are making the
recording.
Use the preceding circuit, but replace the
1mF capacitor (C7) with the 0.1mF capacitor
(C2). The sound is a little different now, and
the green keys can change it.
Turn on the slide switch (S1).
Move the lever on the
adjustable resistor (RV) around
near the left (not the middle or
right). Press any of the blue
keys for more effects. Pressing
the green keys may not do
anything.
