How To: Make your own lite-on probe for an Xbox 360

You like all things Xbox so instead of just playing with it try making your own stuff. You can make a your own Lite-on probe for your Xbox with items you can pick up at RadioShack or a comparable electronic store.

Things you will need
- DB9 serial connector - Female (pic above shows backside)
- D-Sub connector hood (not show in this pic)
- NPN transistor
- 1K resistor
- 10K resistor
- spring from ink pen
- alligator clip
- wire from ear buds
- soldering iron
- solder paste (flux)
- solder
- tweezers
- wire clippers
Step 1 - Attach alligator clip
- Take one end of ear bud wire, clip off what ever is there, and separate wires a few inches.
- Slide one wire through alligator boot.
- Strip wire, apply flux to wire and clip, solder together.
- Slide boot over clip.
Step 2 - Attach probe (spring)
- Stretch out one end of the spring.
- Clip end with wire cutters and straighten out.
- Solder 2nd wire (same end that alligator clip is on) to spring.
- Tuck some of the wire in to the spring. This isn't necessary but I did it so there wasn't tension on the solder joint.
Step 3 - Readying the npn transistor
- Using tweezers, bend legs.
- Using wire cutters, clip legs.
- Solder 10k resistor to the "Base" leg.
- Take other end of ear bud wire, clip off what ever is there, and separate wires a few inches.
- Solder wire to other end of 10k resistor. Use the same wire that has the spring on the other end.
- Solder 1k resistor to other wire. It'll be the same wire that has the alligator clip on the other end.
Step 4 - Attaching npn to d-sub
- Solder the "Emitter" to pin 5. In the picture, pin 5 is top, outside pin.
- Solder the "Collector" to pin 2. In the picture, pin 2 is the top, second pin in from the left.
- Solder other end of 1k resistor to pin 2.
- Attach d-sub hood.
That's it. Your probe is complete. The spring runs to the R707 hole on the Lite On board. The alligator clip runs to a 5 volt source
