DIY Car Speaker Phone with CB Mic
A project I've been trying to do for the longest time is to build a home made speaker phone for my car. There used to be a car phone in it from the pre-cell phone ages and its always sparked my imagination.
Basically, from my cell phone's 2.5mm jack to a speaker and to a mic.
Now, I have a CB Radio in my Cruiser and it has a built in PA. So what ever I say will come out a 3.5mm jack, very convient for the input for this project.
However, I'm a dummy when it comes to speakers. I would have to build a small little loud speaker that would project the sound from my phone.
I took apart a headset, so I have the plug for the headset.
Now what I don't know is how the wires are arranged in the headset wire and what's the best way to built that speaker from a 2.5mm jack output. The input isn't much of a problem, just gotta figure out which wire in the headset wire is the input... probably red.
I'm not much of a electrical guy and I don't currently own a soldering iron. I just have 180w welder.
