Instructions
Obtain the necessary components. Organize the work area by arranging all components on a well-lit surface at a comfortable working height.
Prepare the four-conductor 3.5mm mini jack for modification. If you are unsure what the mini jack looks like, just imagine the end of a pair of headphones. The pointy metal part you plug into an iPod or an MP3 player is a 3.5mm mini jack. Split open the cable from the back of the mini jack and separate the four wires (green, blue, purple and red) from each other.
Connect the red wire from the four-conductor 3.5mm mini jack to a female 3.5mm mini jack. The end of the red wire should be split into two, and each split end should be connected to one side terminal of the female mini jack. Hold down the two red wires from the male so they are in contact with the side terminals of the female and solder.
Split the end of the blue wire into two blue wires. Connect one end of the blue wire to the central connector of the female from Step 2. Connect the other blue wire to the central connector of the other female. The female from Step 2 is for the microphone and the other female is for the headphones. Solder connections firmly.
Connect the green wire and the purple wire to the side connectors of the female you use for the headphones. Hold down the wires one by one and solder the connections. This adapter can now be used to connect a regular microphone to a PSP.
Plug in the male to the headphone jack of the PSP. Plug in the microphone to one of the female mini jacks, and the PSP headphones to another female mini jack. Test the adapter by making a call from Skype.
