Here is my tutorial on how to install an IR adapter and optional extra USB port in your PS3 and a couple of tips on setting up a Harmony remote.
Items you need:
AUVIO™ Universal Remote Receiver for Playstation®3 (Costs $3 on Radio Shack website)
Female USB Connector (Optional)
Flux (Optional but preferred)
Hot Glue Gun
Drill (I used a 5/32″ drill bit)
Universal Remote (Preferably a Harmony)
Lets get started. Obviously first you will need to disassemble your Playstation all the way down to being able to take off the metal shielding on the bottom of the motherboard, there are plenty of tutorials on how to do this (Fat, Slim) so I will not get into that. Here is what you need to look for once you have the motherboards bottom shielding off.
Now it is time to slip the hub, IR adapter, and IR sensor into place. I put the hub next to the hard drive, the IR adapter partially under the fan, and hot glued the IR sensor in the hole. I also applied hot glue to every open contact on the bottom of the IR adapter because it is going to be resting on metal. Don’t want to cause any shorts.
Now when you are setting up your Harmony remote (mine is a 688) for it you will want to choose “DVD”, manufacturer “Sony”, and the model number “BDP-S350″. You are going to need to customize the buttons if you want the “OK” and “Stop” buttons to work. All you have to do is make the command for the Stop button “Select” and the command for the OK button “Stop”. Update your remote and you are all set. It even works in Multiman.
