The idea for the Clear box comes from an article in
the newsletter 2600.
The clear box works on 'post pay' coin phones, pay phones that
require money only after the connection has been made. The way
this works is: After the connection is made the mouthpiece
of the phone is muted but not the earpiece, free calls to
dial-it services can be made with these phones.
In order to talk to the person you called without
paying (NOTE: It is against the law to do this!!)
Take yourself down to your nearby electronics store and get
a four transistor amplifier and a telephone suction cup
inductive pick-up. Put the pick-up on the earpiece and plug
it into the output of the amplifier, and plug a microphone
into the input. You then talk into your microphone and
listen normally through the earpiece.
Radio Shack sells an item that wont need much
modification,and that should work the same as the above
construction. It is their 'Portable snap-on handset
amplifier' (Part # 43-238) Their description says to
put it on the earpiece and it will boost the callers voice
to five times the normal level. In order to make this
function like a clear box one would have to take the
amplifier apart and remove the internal speaker, in
it's place, connect the suction cup inductive pickup.
Place the pick-up (which is now the speaker) to the
earpiece of the payphone, and talk into the microphone
of the amplifer.
The line will not cut off, and will wait forever
for you to put the coins in.
Note also that these types of payphones are not
connected to the tsps in the same way as normal payphones.
The phone does all the charging and not the Central Office.
It is because of this, that a phone connected to the
lines BEFORE the payphone would act just like a normal phone.
So get out your smallest phone, cut off the jack and strip the
wires. connect t
he wires to two alligator clips. Then you can
clip onto the payphone's wires BEFORE they
connect to the payphone, you then have a normal telephone line
that you dont pay the bills on!
