54 Hacking the Xbox: An Introduction to Reverse Engineering What You’ll Need The following is a list of the equipment that you’ll need to complete this project: • Low-wattage soldering iron with a fine point tip • Solder • Flux and soldering iron tip cleaner (optional) • Small flathead screwdriver • T-10 bit Torx driver • Two low voltage (3 volt) blue LEDs in a T-1 (3 mm) case • Masking tape for holding parts in place during soldering You can substitute any color LED that you like, but it must turn on at a voltage of around 3 volts and have a T-1 style case. Pay attention when buying your LEDs, because many blue and white LEDs are rated to work only at 5 volts. The LED used here is a Lumex SSL-LX3044USBC which you can buy through Digi-Key (www.digikey.com); part number 67- 1747-ND. (For the budget-conscious, Digi-Key can send the LEDs via United States Postal service’s first class mail. Note that there is a $5 handling fee for orders through Digi-Key that are less than $25.) If Digi-Key’s minimum order restriction is a problem for you, Mouser Electronics (www.mouser.com) also has a line of blue LEDs, and they have no minimum order. An example part is the Kingbright blue LED in a T-1 case with a water clear lens; the Mouser stock number is 604- L7104PBC/H for the brighter, slightly higher voltage version, or 604- L7104QB/D for a version that operates at a lower voltage but with a lower rated brightness. You can also use a bi-color LED if you would like to maintain the error condition LED functionality as well. The Xbox requires a common-cathode bi-color LED in a T-1 case with three leads. Unfortunately, bi-color LEDs with a blue element in the smaller T-1 case are very difficult to find. Removing the Xbox Front Panel The Xbox front panel is a molded piece of ABS plastic that is held in place with four T-10 torx screws and three molded friction locks. The electronics in the front panel connect to the Xbox motherboard through a single ninewire connector that winds its way through a hole in the metal electromagnetic interference shield. Open the Xbox as instructed in Chapter 1. Lift and move the hard drive and the DVD drive up and toward the back of the box just enough to expose the front edge of the Xbox motherboard. You should not have to
Chapter 3 - Installing a Blue LED 55 Figure 3-1: Position the disk drives so that the front edge of the motherboard is exposed. undo any of the disk drive cables. Figure 3-1 illustrates how your Xbox should look after these steps. Note Older Xbox models will have a vertically mounted PC board near the front of the Xbox. This PC board can be removed by grasping the board and pulling it out of its socket. You may find that removing the vertically mounted PC board is helpful when trying to release the middle friction lock of the front panel. Do not forget to replace the PC board when you are done! Remove the four screws that hold the front panel assembly in place (see Figure 3-2). Detach the front panel wire connector from the Xbox motherboard as shown in Figure 3-3. A firm, steady force is all the connector should require. (Do not jerk the connector out, because you may damage the wires.)
