  What is a LOUD box?? Well if you've ever started a conference you'll
know that a lot of the times the conferees cannot hear you that well.
Well this little BOX should clear up that problem. First thing you want
to do is MAKE it, so get to that and come back when you're done. Ok, we
now have the circut done, so heres what you'll do. First open up your
phone and find the wires going to the mouth piece and cut them. Not
connect the wires running from the microphone to the input line and the
other wires running to the output line. There you have it, just turn it
on, and ajust the volume control and the people at the other end will be
able to really HEAR what you are saying.
