  10.              (3) 1.4k OHM resistors
  11.              (2) 2N3904 transistors
  12.              (2) Photocells
  13.              (2) LED's (Make sure they're real bright)
  14.              Box to contain it in that will not allow sunlight in it.
  15.              Some wire (Red and green for easiness sake)
  16.  
  17.  PROCEDURE
  18.  
  19.     Light from the LED's must shine directly on the photocells.  You may have
  20. to have the LED touching the photocell for it to work.

  60.     The 1.4k resistor is variable and if the second part of of the box is
  61. skipped the box will still work but if someone picks up the fone they may
  62. report it to the Phone Co.  The 1.4k will give you good reception with little
  63. risk of the Gestapo knocking at your door.
  64.  
  65.     Take two green wires and strip the ends.  Twist one end of each together
  66. so they make one wire.  Connect it to Green #1.  Label this 'Line #1'.  Do the
  67. same but with red wire and attach it to Red #1.  Repeat the process for Red #2
  68. and Green #2 and label it 'Line #2'.
  69.  
  70.  INSTALLATION
  71.  
  72.     Find two fone lines that are close together.  Label one of them 'Line #1'.
  73. Cut the phone lines and take off the outer covering.  You'll see 4 colored
  74. wires inside.  Cut the yellow and black wire off and strip the red and green
  75. wires on both lines.
  76.     Line #1 should be in two pieces.  Take the green wire of one end and con-
  77. nect to one of the green wires on the box.  Take the other half of the fone
  78. line green wire and connect it to the other green wires on the gold box.  Do
  79. the same for the red wires on the other line and the red wires on the box.
  80.     Now, find out what number you hooked up the gold box to.  Go home and call
  81. it.  You should get a dial tone and you can dial out.  If not, re-check every-
  82. thing.  If it still doesn't work, pack up and go home.
