[Dispater's Note]: This box was fuckin bullshit in it's original form. I
|
|||
|
|
made the schematic easier to undertand and added the resistor so the
|
|||
|
|
damn thing doesn't blow the transistor every fucking time. I must have
|
|||
|
|
went through 5 of 'em. It is important to keep in mind thatas the
|
|||
|
|
voltage drops in the batter the tone calibration will change. The
|
|||
|
|
only way to stop this is to have a DC power supply. One last thing.
|
|||
|
|
Don't waist your money on cheap ass parts at Radio Shack.

The Pearl Box:Definition - This is a box that may substitute for many boxes
|
|||
|
|
which produce tones in hertz. The Pearl Box when operated correctly can pro-
|
|||
|
|
duce tones from 1-9999hz. As you can see, 2600, 1633, 1336 and other crucial
|
|||
|
|
tones are obviously in its sound spectrum.
|
|||
|
|
|
|||
|
|
Materials you will need in order to build The Pearl Box:
|
|||
|
|
========================================================

|
|||
|
|

The potentiometer area is rigged so that the left pole is connected to
|
|||
|
|
the center pole of the potentiometer next to it.

|
Correct operation of The Pearl Box:
|
|||
|
|
===================================
|
|||
|
|
|
|||
|
|
R1 is the knob for the ones place, R2 is for the tens place, R3 if for the
|
|||
|
|
hundreds place and R4 is for the thousands place. S1 is for producing the all
|
|||
|
|
the tones and S2 is for power.
|
|||
|
|
Step 1: Turn on the power and adjust the knobs for the desired tone.
|
|||
|
|
(Example: For 2600 hz- R1=0:R2=0:R3=6:R4=2)
|
|||
|
|
Step 2: Hit the pushbutton switch and VWALA! You have the tone. If you don't
|
|||
|
|
have a tone recheck all connections and schematic. If you still don't have
|
|||
|
|
a tone call Brainstorm BBS:612-345-2815, The Bay:415-775-2384 or Pirate's
|
|||
|
|
Harbor:617-720-3600 and leave me e-mail stating what the scene is.
