(requires some electronic components, and basic soldiering skills)
Step 1: Explanation:
So the idea was born and after a quick trip to my local electronics store, so was the final product.
Step 2: The diagram:
The bottom right is the mic line, this is where you plug in the microphone for your phone conversations.
Second from the bottom on the right is the phone plug. This will require you to obtain a female 2.5mm stereo jack and get a male to male 2.5mm stereo cord to plug into your phone. I used a 3.55mm female stereo jack on the body, and made my own male 3.55mm stereo to male 2.55mm stereo cord.
Third from the bottom on the right is the auxilary plug. This is where your music comes in from. Basic 3.55mm female stereo jack.
Top left is obviously where you plug in your headphones.
Step 3: Topology
Suprisingly, this rats nest wasn't too hard to soldier together, and held it's shape once removed from the cardboard test housing.
Just remember to PLAN AHEAD!
