Introduction: How to Hack Ps3 Portal of Power to Add USB Power

Picture of How to Hack Ps3 Portal of Power to Add USB Power

The original portal of power (pop) never had USB or DC power. Those 3 AA batteries every few days was getting annoying.

I am no expert in electronics but a little reading and a little logic seems to have worked here.

You will need:
A wire stripper
Pliers
Soldering iron
Solder
A Phillips screwdriver
a 1 ohms resistor
A USB cable with type A head. (see below)


Step 1: Where to Connect

Under the rubber grips, there are 4 screws. Take these off and the pop will easily open.

Step 2: Where to Connect

The Negative terminal has a black wire soldered on. On the opposite far side, although my pop did not have a red wire, I could tell from the underside something was soldered on.

It's possible to solder directly to these points. I just thought it was easier to solder to the battery terminals as you'll see.

Step 3: Where to Connect

I used an old usb wire that I had laying around.
Cut it at the tip and peel the cable back to reveal the 4 wires inside.

We only need the black and red wires which are what carries the power down the wire. I chopped the other 2 off.

Use a wire stripper to reveal the copper under the coloured wire.

I used a wood/metal file to make a small hole in the side of the pop as you can see in the picture to feed the USB wire through to the battery terminals.

I also held the wire in place with a cable tie.

Step 4: The Soldering Part.

For this bit I thought about the voltage that would accumulate from 3, 1.5v AA batteries. The pop needs 4.5 volts and USB carries 5 volts from whatever it's connected to.

I used a resistor to lower the power being carried down the usb by 0.5 volts using a 1ohms resistor.
I am really not into electronics at all. I used an online calculator to help me pick up the correct resistor. http://led.linear1.org/1led.wiz 

As you can see in the image, I soldered the negative from the usb (black) to the negative battery terminal. I soldered the resistor between the positive usb wire and the positive cable terminal.

Step 5: Complete

I tested my the power from the pop with a multimeter while the pop was turned on. The voltage had indeed decreased from 5 volts to 4.6.

I now have happy kids not moaning that their batteries have run out and a portal of power that connects to the PS3 USB socket. :-)
