The Blast Box

Ever want to really make yourself be heard? Ever talk to someone on the
|
||
|
|
phone who just doesn't shut up? Or just call the operator and pop her
|
||
|
|
eardrum? Well, up until recently it has been impossible for you to do
|
||
|
|
these things. That is, unless of course you've got a blast box. All a
|
||
|
|
blast box is, is a really cheap amplifier, (around 5 watts or so)
|
||
|
|
connected in place of the microphone on your telephone. It works best
|
||
|
|
on model 500 AT&T Phones, and if constructed small enough, can be placed
|
||
|
|
inside the phone.

Usage
|
||
|
|
|
||
|
|
Once you've built your blast box, simply connect a microphone (or use
|
||
|
|
the microphone from the phone) to the input of the amplifier, and
|
||
|
|
presto. There it is. Now, believe it or not, this device actually
|
||
|
|
works. (At least on crossbar.) It seems that illinois bell switching
|
||
|
|
systems allow quite a lot of current to pass right through the switching
|
||
|
|
office, and out to whoever you're calling. When you talk in the phone,
|
||
|
|
it comes out of the other phone (again it works best if the phone that
|
||
|
|
you're calling has the standard western electric earpiece) incredibly
|
||
|
|
loud. This device is especially good for PBS Subscription drives.
