Hi,

Looking to do something similar.

I have already made a USB Lite-on key dumping probe. This only cost me £3 and was easy to do. You can see what I and others did in this thread including ebay link for cable. The tricky bit is determining the correct colour cable and installing the correct drivers.

From research on this site and others powering the drive with an eject button may also be straightforward and simply require a few parts to make a cable. I think Mode B can be achieved through software such as Jungle flasher on all drives so no hardware requirement (can some one confirm if this is the case, I certainly did this on an Hitachi 78FK drive, no need for LED as having to press eject twice verifies it is in mode

.

I think I need to do the following to make a cable to power any DVD drive with eject.

1. A spare Xbox DVD power cable. Chop it in half and retain the bit that goes to the DVD.
2. A PC 4 pin Molex cable extender (one with plug on one end and a socket on the other).
3. The Molex will supply +12V, +5V and GND.
4. Wire Pins 1 & 3 of the DVD power cable to +12V on the Molex connector not socket
5. Wire Pin 5 of the DVD power cable to +5V on the molex.
6. Wire Pins 0, 2, 4 and 6 to GND on the Molex.
7. Wire Pin 8 (Eject) to a crocodile clip.
8. No need to wire pin 7 (+3.3V), no need to wire pin 9 (Tray status)

To eject/close the drive we simply attach the crocodile clip to ground (metal case on PC) or nothing.

The above cable assumes a few things that I have yet to verify.

1) All of the drives generate their own +3.3V internally so no need to wire this.
2) Pin 8 floats to logic 1 if unconnected making the eject work.

Can anybody confirm either of these two points please?

If all the above is true then you can make the required cable for the cost of a croc clip, some spare wire, an Xbox DVD power cable and a molex cable extended (probably already got one in your PC). So probably less than £5.

You can make it more snazzy by wiring a small resistor (220 Ohm) to a LED and then to GND in series. This will tell you the status of the eject via the LED.

I only found this yaywoop's extractor:

For the drive power with leds for mode b(on and off), you could add a simple led for when the actual device is turned. http://forums.xbox-s...howtopic=651212
Wiring for probe

The yaywoop extractor should work fine & this is also what ruley is referring to.

If you click on the link in my original post though you will find an easier (almost off the shelf solution that only requires that you solder a needle to a wire) to get a USB rather than serial interfaced probe. You could of course wire the led in this method like ruley shows in his diagram.

It is based on a cell phone data cable. Far easier in my opinion than messing around with transistors and serial ports.

Ruley does show something important in his picture though. He has connected the PC case to the Xbox case. Just use some crocodile clips. This is precautionary but worth doing anyway.

Any small LED should do. Just wire it the correct way around.

Ruley: You seem quite knowledgable. Do you know the answer to the 3.3V questions I posed earlier?

I edited the extractor with LED, here is the schematic:

Is it OK? I am planning combine it with power adapter. But I must first take some information about building power adapter from thread from ruley.

looks all good to me

Use this one (from RDC),Very easy to follow. I finished mine w/o problems.

Sorry .. didn't noticed that the post was referenced above.... it works anyways.**
jo.

Can you take some photos of your finished kit? I would like to have as much material. I read the RDC's tutorial, but I don't know how to make kit in real. Thanks
