2 red led's (the more light produced the better), a box that
will not let light in, and red and green wire.
light from the #1 led must shine directly on the photocell #1. the gold box I
made needed the top of the led's to touch the photocell for it to work. the
same applies to the #2 photocell and led
1 *Schematic is as close to the orginal
as possible

1.4K
the 1.4k resistor is veriable and if the seccond part of the gold box is
skipped it will still work but when someone picks the phone up they will hear
a faint dial tone in the background and might report it to the gestopo er...
(at&t). 1.4k will give you good reception with little risk of a gestopo agent
at your door.
now that you have built it take two green wires of the same lenth strip the
ends, twist two ends together and connect them to green1 and place a peice of tape on it with line #1 writing on it. continue the process with red1 only use
red wire. repeat with red2 and green2 but change to line #2.
how to install
you will need to find two phone lines that are close together. label one of
the phones lines line #1.cut the phone lines and take the outer couting off
it. there should be 4 wires cut the yellow and black wires off and strip the
red and green wires for both lines.
line #1 should be in two peices take the green wire of one end and connect
it to the one of the green wires on the gold box. take the other half of line
#1 and hook the free green wire to the green wire on the phone line. repeat the process with red1 and the other line.
all you need to do now is to right down the phone numbers of the place you
hooked it up at and go home and call it. you should get a dial tone!!! if not
leave me a message on the modem madness bbs 516-569-0589 or try changing the emitter with collector. oh and hooking it up to a payphone is a federal offence and is illeagal to put on any phone. i recommend you see your local police department before doing anything said in this article.
