Anything you connect to the phone lines is *supposed* to be FCC registered, to make sure it won't repairmen or damage equipment.  The gadgets des-
cribed in this file do NOT apply any extra voltage to the line, and should be safe.  If in doubt, ith the phone company before connecting any stuff to your line.  (These gadgets do not put n xr rnger equivalence" on your line, either.)

          CONFERENCE CALLER

If you have two phone lines, you canthis simple attachment to set up your own conference calls.  Yever pay to have an operator set them up for you again.  Once you've called the two other pol nyu two lines, you just throw the switch.
All three of you can now talk to each other.

Phone lines carry voices as audio frequencies superimposed on DC control voltages (around 40-50 von not in use, with higher pulses when ringing; around 10 volts when a phone is being used -  ogtte exact numbers, but those are close.)

The two lines can be connected through capacitors, so the audio passes between the two, but the DCes don't interfere with each other.  (If you simply short the lines together, the phone comaymyntlike it!)

Use this simple circuit:

             ! !
 red --------! !---o: o------ red
             ! !    :
(line 1)            :      (line 2)
             ! !
green--------! !---o  o------green
             ! !
              ^     ^
       capacitors  DPST
       .1 to 1 uf  switch
    (not critical)
(do *not* use polarized electrolytics!)

(This circuit is similar to the other conference caller mentioned on the Roman Forum, which doesn'the capacitors.)

             HOLD BUTTON

This gadget also is a variation on one posted on the Roman Forum.

Shorting the line is not a good idea.  A resistance of 1-2K is enough to hold the line, without mae line look screwed up to the phone company.


red ------o  o----\\\\------ green

          SPST    1-2K
         switch

(It doesn't matter which direction you connect this circuit in -- red-to-green and green-to-red bo.)

If you like, you can add an LED that will light whenever you have someone on hold.  Just connect tin series with the switch and resistor (now about 500 ohms to 1.5k, depending on your LED - xeiet).  Like this:

                           ^^
                          !\ !
red -----o  o----\\\\-----! >!--- green
                          !  !

       SPST sw. .5-1.5K    LED

This circuit (with the LED) only works if it's connected in the right direc-
tion.  Phone wiring isn't always done right; before you wire this one in permanently, try switchined and green wires, and leave it in the direction that works.


                ENJOY!

*      How to build a BLACK BOX       *
*                                     *
***************************************

  To all who dare --

     What is a BLACK BOX?   A BLACK BOX
is  a device that is hooked up to  your
fone  that fixes your fone so that when
you get a call,  the caller doesn't get
charged for the call.  This is good for
calls  up to 1/2 hour,  after 1/2  hour
the Fone Co.  gets suspicious, and then
you can guess what happens.

The way it works:

     What  this little beauty  does  is
keep the line voltage from dropping  to
10v  when  you answer your  fone.   The
line is insted kept at 36v and it  will
make  the  fone think that it is  still
ringing while your talking.  The reason
for the 1/2 hour time limit is that the
Fone CO. thinks that something is wrong
after 1/2 an hour of ringing.

     All  parts  are  available   Radio
Shack.   Using the least possible parts
and arangement,  the cost is $0.98 !!!!
And  that  is  parts for two  of  them!
Talk  about  a deal!   If you  want  to
splurge  then  you can get a  small  PC
board,  and  a switch.   There are  two
schematics  for this box,  one  is  for
most  normal fones.   The second one is
for  fones  that don't  work  with  the
first.  It was made for use with a Bell
Trimline touch tone fone.

  **  Schematic 1 for most fones  **
  **         LED ON: BOX ON       **

        !              !
        ------>/<-------
              SPST



Parts:  1 1.8k 1/2 watt resistor
        1 1.5v LED
        1 SPST switch

You  may just have two wires which  you
connect together for the switch.


  **  Schematic 2 for all fones  **
  **        LED ON: BOX OFF      **

Parts:  1 1.8k 1/2 watt resistor
        1 1.5v LED
       1 DPST switch


     Here is the PC board layout that I
recommend  using.   It  is neat and  is
very easy to hook up.

     Once you have hooked up all  the
parts,  you must figure out what set of
wires  go to the line and which  go  to
the fone.   This is because of the fact
that LED's must be put in, in a certain
direction.  Depending  on which way you
put the LED is what controls what wires
are for the line & fone.

How to find out:

     Hook  up the box in one  direction
using one set of wires for line and the
other for fone.

*NOTE*  For Model I switch should be OFF.
*NOTE*  For Model ][ switch  should  be
        set to side connecting the led.

     Once  you have hooked it up,  then
pick up the fone and see if the LED  is
on.  If it is, the LED will be lit.  If
is  doesn't light then switch the wires
and try again.  Once you know which are
which  then label  them.   *NOTE*  - If
neither  directions  worked  then  your
switch was in the wrong position.   Now
lable   the   switch  in  its   current
position as BOX ON.

How to use it:

     The purpose of this box is not  to
poeple  who  call you so it would  make
sence  that  it  can only  be  used  to
receive! calls.   When the box is  *ON*
then you may only recieve calls.   Your
fone will ring like normal and the  LED
on  the box will flash.   If you answer
the fone now, then the LED will
light and the caller will not be charged.
Hang  up  the fone after you  are  done
talking like normal.   You will not  be
able  to  get a dial-tone or call  when
the  box is on,  so turn the box  *OFF*
for  normal calls.   I don't  recommend
that you leave it on all the  time,  as
you don't want it to answer when Ma
Bell calls!


               Silver Boxing


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 bontact 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
column tones.


    HOW TO BUILD A HOLD BUTTON

I WILL DO THIS STEP BY STEP:

  1. YOU CAN EITHER DO THIS FROM THE
     OUTSIDE OR FROM THE INSIDE OF
     YOUR PHONE. FIRST TAKE THE RED
     AND GREEN WIRES AND STRIP DOWN
     A PIECE OF WIRE SO YOU CAN ADD
     ANOTHER PIECE OF WIRE TO IT.

 2.  ONCE YOU HAVE THE OTHER PIECE'S
     OF WIRE ADDED TO THEM GET A
     A TWO WAY TOGGLE SWITCH SO THAT
     YOU CAN SWITCH THEM FROM HOLD TO
     TALK POSITION

 3.  TAKE THE TWO EXTRA PIECES OF
     WIRE AND HOOK THE ONE THAT IS
     HOOKED TO THE GREEN TO ONE OF
     THE TERMINALS ON ONE SIDE AND
     THE RED WIRE TO THE OTHER SIDE
     OF THE TERMINAL

DIAGRAM:

  RED   GREEN

  BLACK  YELLOW

LEAVE THE RED AND GREEN HOOKED TO
THERE TERMINALS IN THE BOX BUT JUST
RUN A WIRE FROM EACH OF THOSE
TERMINALS AND HOOK ONE WIRE TO ONE
SIDE OF THE SWITCH AND THE OTHER
WIRE TO THE OTHER SIDE OF THE SWITCH
