With all the portable gadgets on the market that play high-resolution games, it's unnerving to many fans that out-of-the-box Bluetooth voice capability doesn't come standard on many of them. Even on products with Bluetooth onboard, its functionality can be limited. By now, you probably already have your soldering iron out, so let's proceed.

Wirelessly chatting with multi-player games on that aging PlayStation 2 and using Bluetooth voice capability on the Sony PSP is possible with this rather ingenious but somewhat convoluted modification. It will not only require a USB interface to your PS2 or PSP, but then an audio connection from that USB interface to the Bluetooth box you'll use from that disassembled Cardo Bluetooth dongle.

Needed: Sony PSP (of course), Bluetooth adapter for non-Bluetooth phones (the Cardo unit is used in this example), some electronics and soldering expertise (and steady hands), and the USB box from that PS2 you have sitting around (if not, you'll need to go buy this). If you're ready for this one, look here and engage the project carefully. The end result will be some more wires (argh!), but none attached to anything hooked on your ear at the very end.
