INTRO: After reading the fucked up shit on the original pearl box, I decided
|
|||
|
|
that there was an easier and cheaper way of doing the same thing with
|
|||
|
|
an IC and parts you probably have just laying around the house.
|
|||
|
|
|
|||
|
|
PARTS: CD4049 RCA intigrated circuit
|
|||
|
|
.1 uF disk capacitor
|
|||
|
|
1 uF 16V electrolitic capacitor
|
|||
|
|
1K resistor
|
|||
|
|
10K resistor
|
|||
|
|
1meg pot
|
|||
|
|
1N914 diode
|
|||
|
|
some SPST momentary pushbutton switches
|
|||
|
|
9 Volt battery & clip
|
|||
|
|
and miscalanious shit you should have laying around the house.

EXTRAS:
|
|||
|
|
To keep tones that you wanna use frequently like 1850 Hz then all you
|
|||
|
|
have to do is put in a variable resistor and adjust it to where you
|
|||
|
|
have the correct tone, then just put a push-putton switch on the line.
|
|||
|
|
You can link them together in a chain, etc.
