Building your own Lite On probe - guide with pictures

This discussion thread has 134 messages.

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.



- 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....498&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.

its coming, i wanted to break it up

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.

I can already tell this is going to be way easier to understand than the old tut from xs..... you da man!!

If you send me questions on Live about modding or anything related i will block you. Dont be an idiot.

awesome job matey nice and clear instructions

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?
#10
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.
#11
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?
#12
They look like this? http://www.radioshack.com/product/index.jsp?productId=2062305

The 1/4 watts are usually blue. And they're fine to use. That'd actually be better because 1/4w are smaller than the 1/2w, so that would give you more space when installing your d-sub hood (if you're using one).
#13
Cheers bhetrick, you rock matey!!, i may post pics of my probe when i'm done :)
#14
would 1/8 watt resistor work?
#15
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
#16
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

my power supply doesnt give any molex cables. what else can i use for 5v.
#19
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
#21
is there anyway to confirm if my soldered connection is ok before trying it out on my 360?

even if it isnt good it still wil not mess up your console in any way.
#23
don't use the orange colored wire as i think it is 3v. the yellow is 12v, red is 5v & black is ground. if have a multi-meter or can borrow 1 then use it to confirm the voltage at the soldered connections.
#24
i just want to know i did the connection right, cos i aint that good with a soldering iron
#25
You can test it with a multimeter.
