Since I lost my iPod Nano (!!! cries !!!), I have been desperately in need for a 2.5mm stereo to 3.5mm stereo conversion cable to hook up my BlackBerry phone with the AUX-IN port in my car so that I can listen to some music on my phone. Rather than spending $7 to get it from The Souce CC, I’ve decided to make my own. Should be pretty straight forward. Here are some instructions for whoever that is interested in what I did.

Tools used: Wire cutter, volt meter, soldering kit (gun + iron), 2.5mm headset cable, 3.5mm cable, electrical tape. First, strip the plastic portion off the cables carefully, becareful not to damage the copper strips inside. After getting rid of the outter layer, more cables to strip! Strip them all. The tiny ones are kind of hard to work with, had to use a fine cutter.

Then use the voltmeter to test to see which wire corresponds to which contact. Turn the dial on the meter to 150mA ohm. When the two ends are connected the needle will flap up. Use the soldering gun to put some melted iron onto the bare wires so they will “stick” better and easier onto the other wires (See the wires with soldering irons on them. They turned kind of black for some reason =( )

Now solder up the right cables. After that wrap up the contacts with electrical tape carefully, make sure the bare part of the wires don’t touch. Perfectly done. Time to hook it up for some music!
