    I've seen more than a few people now looking to build their own probe, to save money, but they can't quite grasp the drawing in the Xbox-Scene "Liteon Key For Free!" thread. http://forums.xbox-scene.com/lofiversion/index.php/t668247.html

    So I figured I put up some simple to follow pictures of how I built one.

    So to start, I'll list the parts I used.
    [​IMG]

    - 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
    - alligatar clip
    - wire from earbuds



    Tools used.

    - soldering iron
    - solder paste (flux)
    - solder
    - tweezers
    - wire clippers

    Here's links for the important parts. Obviously some of you won't have a Radio Shack near you, but at least the links will give you some necessary details so you know what to look for.

    - female D-Sub connector: http://www.radioshack.com/product/index.jsp?productId=2102498&tab=summary

    - D-Sub connector hood: http://www.radioshack.com/product/index.jsp?productId=2103993

    - NPN transistor: http://www.radioshack.com/product/index.jsp?productId=2062609

    - 1K resistor: http://www.radioshack.com/product/index.jsp?productId=2062323

    - 10K resistor: http://www.radioshack.com/product/index.jsp?productId=2062330

    - alligatar clip: http://www.radioshack.com/product/index.jsp?productId=2062236

    A note on the resistors used. My pictures and the links above show 1/2 watt resistors. You can use a lesser watt resistor. I just used the 1/2 watt because that's what I had on hand.

    A note about the transistor. It'll have 3 legs; a Base, a Collector, and an Emitter. When you purchase one, the back of the packaging usually shows which leg is which.

    So let's get started.

    Step 1 - Attach alligator clip
    - Take one end of earbud 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)
    - Streach 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 earbud 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. In the Xbox-Scene "Liteon Key For Free!" thread ( http://forums.xbox-scene.com/lofiversion/index.php/t668247.html ), they show the 5 volt running to a molex connector. You can use one of them while you have your pc open.

    Myself, I have the original Team Xecuter Connectivity Kit they sold a couple of years ago. Because I use that for my power and ejecting (instead of the 360), I just attach the alligator clip to it to get my 5 volts.

    Nice work man. Now you'll have about a million questions from kids who still won't understand what they're doing.

    Since I have a job and kids,wife,ect... I just ordered a ck3 pro and probe.

    I still might build this just to do it when I have the time. But good work on the guide.

    Fantastic job on the tut there, thats really easy to understand!!
    Couple questions though if i may:

    A) can you use a 12k resistor in place of the 10k ( i only seem to have a 12k atm)
    B) where the croc clip is i assume you can use a molex connecter with the 5v wire intact instead?

    A. I can't give a positive answer for the 12k.
    B. Yes, the croc is the 5v, so you could swap it for a different adapter. As long as it's going to a 5v supply, you're fine.

    One more quick question, i managed to get a blue 1k resistor, and a blu 10k resistor..i am guessing these will do fine even though they are a different color to yours?

    would 1/8 watt resistor work?

    Hi,

    I was just wondering why that USB converter for the 9-position isn't on the parts list...

    Is there another way that I can connect it to my PC to dump the key from my drive? Im so new at making my own electronics components...

    Thanks

    An 1/8w should be fine.

    The 232 converter wasn't on the list because it's not necessary. All you do is plug the d-sub in to the serial port on the back of your pc. Now... if your pc didn't have a serial port then you would either need the usb converter or you could just buy a serial card.

    yep and here is an example if anyone hasnt seen a serial to usb converter cable before. this also requires the usb to serial drivers be installed. they can be found with a search. http://www.usbgear.com/USB-Serial.html

    do you have any white 4 pin connectors on you psu? the red wire is 5v & the black is ground.

    i do not. but i do have alot of unused sata power connectors. these have 5 wires (orange, black, red, black, and yellow). could i just cut off the connector and use the red wire, or would that be bad for my power supply. i also have some old molex connectors from my old computer so if possible i could just replace the sata w/ molex. idk what the orange wire is for though
