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.
STATE-OF-THE-ART-NEATO TEXT SCHEMATIC:
+ 16V 1uF -

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.
