How to build a SILVER box:


Tools and materials :  Soldering Iron, Solder, Some 22 ga. wire, a SPDT =
switch,
and a screwdriver.


1) Unscrew your phone (must be a touch tone, desk type) 2) Remove the =
mounted
pad and take the clear plastic cover from the bottom. 3) Hold the pad =
with the
numbers 0, *, # facing you, and turn it upside down, so you can see the =
yellow
pc board. 4) You should see 2 black round doughnuts. 5) Position the =
board so
the solder points for the left doughnut face you. 6) Count over four =
points
from the left, and attach a (green) wire to that point. 7) Between you =
and the
doughnuts, there should be 2 long yellow capacitors.  To the right of =
these,
and on the edge of the board there should be 3 gold contacts. We will =
use the
one on the left. 8) The contact originally is spot welded, so snip it =
open. 9)
To the one nearest you, attach a (red) wire to the other one, a (yellow) =
wire.
10) Run the wires out of the phone, and solder the switch. 11) The =
orientation
should be (red) to center. The switch will now alternate between normal =
and
1633hz fourth c=EFlumn tones.
