Project 383

Tone Speed Changer

Set the 500kW adjustable resistor (RV3) to mid-range, turn OFF the

left slide switch (S1), and then turn on the right slide switch. Now

turn on the left slide switch, you hear a beep signaling that you are

recording. Wait for the second beep (about 10 seconds), which

signals that recording is finished. 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.
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. You won’t hear the tone when it is being recorded; you

only hear it during playback.
Replace the 5.1kW resistor (R3) with the 100W resistor (R1), 100kW

resistor (R5), or photoresistor (RP) to vary the frequency of the tone

being recorded.

Light Echo

Turn on the slide switch (S1), and push the press switch (S2). The red

LED (D1) is on while S2 is pressed, and the white LED (D6) flashes.

The adjustable resistor (RV) controls how long the white LED flashes

for, controlling the “echo” of the light.
