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

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