Good idea Drivembig, but If I need the 12v I would rather just pull both the 5v and 12v from a molex. I have a molex connector I cut out of an old PC DVD drive I can use. I used the 5v alone to test the regulator circuit, and just figured I would try without the 12v to see what would happen. Hopefully I will get a chance to test it this weekend.

@Blakey-8

Yes you can do it that way, but it would be easier to just cut the 3.3v wire at the midway point and strip both ends, now just add a third (wire end) and solder them together. You will then have the wire running from the MOBO to the DVD with a pigtail out of the middle. This pigtail is now a 3.3v source

Well, I am not very good at creating schematics, but here is a simple wiring diagram. Note that I am only showing the connections which should be cut to add switches, etc. All other wires/pins should continue along their way.



Any questions, just ask! :)

what does the Drive status switch do?

From what I found using that diagram the tray status switch will eject the tray by lifting the ground.(floating state) The eject button does not function as it essentially puts ground to ground. The #3 wire is closed to ground in a normal state, you need to take it to 3.3v to eject. So by switching it to ground it does nothing. Lifting it will eject the tray also but this is not recommended by any person I talk to or from anything I've read.

One last question (mainly to RayHaque )

Can someone clarify why cutting the 5v power will stop the drive? There's also a 12v and 3.3v line coming into the drive...

Thanks

PS: thanks to RayHaque for great schematic and description.

The 3.3v is created by the MOBO and used to eject the drive/tray status, at this point I'm not sure what the 12v is doing. I do know you only need to kill the 5v to dump/flash the drive though. Just not sure if the 12v has to be present at all.

Yes Ray and Drivem get all respect here, if not for them I'd not even thought of going this far into it.

Okay, thanks guys.

This is what I'm going to build.

Since I don't want to spend $$ on another DVD drive power cable (~7 bucks on ebay) I plan on incorporating the micro-switch and buttons onto the original DVD drive power cable.

I'm going to power the probe with a molex connector (from computer)

This is slightly different from Ray's schematics where he uses the 5v and ground to power his RS232. He's probably planning not keep all that internally where as I intend to have the switches and buttons permanently in the xbox. I think this makes it easier to flash it the next time around since I won't have to worry about plugging the power in the wrong way and it's at least 7 dollars cheaper.

Oh yea, for those cheapskates (like me) you can also follow the schematics to build your own RS232 converter. Of course there are simpler ones where you just use one transistor and a 10k resistor seen here: http://xbox-experts.com/e/pics/yaywoop/sch-1.jpg

but I prefer to build a more "exact" RS232 converter. Besides, my dad's an EE and he has all the components at home anyways...

I'll post pics of it in early june. (I'm away from home at university and my soldering iron is at home... and I have to TA an chemistry course after finals from may to early june)


Thanks guys!


PS: One thing I can't believe is how CK3 and Maximus is selling these things for 50+ (probe + connectivity) when I could build it for less than $10. I'd rather donate money to c4eva...

Your RS232 should work great, but don't expect the CK to function as expected. As your pic states "pin#3 closes the drive when connected to ground". This is done through the eject button. When you power on the 360 the drive is closed i.e. pin#3 is grounded. To eject the tray you can lift (pin#3) ground and put it in a Floating state, or you can momentarily take it to 3.3v (this is what the eject circuit does). It is actually like a single pole double throw push button switch where the second set of contacts are momentary.The NC contact is connected to ground and the momentary contact is connected to 3.3v.

Look at this diagram and then you will understand what I'm saying. His pin designations are different, but easy to follow just the same.

Opps, I meant to use SPDT instead of SPST.

Really, I'm just confused because different site says different things...

2 sites says that pin 3 has 3.3v running through it and that grounding it will eject (open) and 3.3v will close
1. http://i50.photobucket.com/albums/f320/RDCXBG/360DVDPowerConnectorToMolex.jpg
2. http://dwl.xbox-scene.com/tutorial/Xbox_360-HandC-V1_4.pdf

Yet another site says that grounding (0v) will close while 3.3v will eject (open)

http://www.hardwarebook.info/Xbox_360_DVD_Power

Although I'm pretty sure that grounding pin 3 will open the drive... Either way, I'm probably going to stick a multimeter probe into pin 3 and see if it constantly has a 3.3v running through or whether it's grounded before I do anything. If it turns out that pin 3 is grounded when closed, I'll just wire one terminal of the SPDT to pin 6 (3.3v) while the other continues on pin 3.

Here's my schematics (fixed)

Yep had me confused at first also. Read this http://www.kev.nu/360/dvd.html. (there is also a short version)
I think were the confusion lies is in this part
"8a = output : eject (falling edge (0V) closes, rising edge (+3.3V) opens)
8b = output : eject (normally 0V, rising edge of a +3.3V pulse opens/closes tray)
9a = input : tray_status (0V = opening/closing, +3.3V open/closed)
9b = input : tray_status (+3.3V = open, 0V = closed)"

Well good luck and let us know how you make out and if you come across any further info.

Managed to get mine sorted at last :). The probe I made (an old sewing needle) didn't work so I had to bridge the R707 point with a flathead screwdriver. Nethertheless, I managed to get the key first time with Jungle Flasher but I did it three times just to make sure :). Thanks for the help Driveembig.

@darkcurrent

Almost forgot to mention, if you are not interested in a full Ck then the easiest way to do it would be to just place a SPST in the 5v wire and since you will be using the 360 for power you can also use the eject button. That would also mean less things to stuff in the case when done flashing. Also the simple transistor and two resistor probe works just fine. Your schematic is a much better design, but both will work for the Lite-On just the same.

One thing that readers should keep in mind here is that we do this just because. Yes you may save a couple of bucks, but for the most part is that we enjoy this kind of thing. We could go and buy a CK and it would work great, but what would be the fun in that....lol. Just a thought.

As far as the 12v is concerned. The only function that is operating during this process is ejecting the drive. The 3.3v causes the drive to eject, but the eject motor is going to need the 12v to operate. I assume. I haven't verified this yet. I haven't had much time lately.

Can anyone verify this? Thanks.

One thing that I am trying to accomplish is to make everything external of my pc. So I can put the dang cover back on.....lol.

Ayo Umm this is my first post here and I just want to say to drivembig once i saw what you did i just had to do it myself and it worked THX ALOT I refused to pay 26 dollars or sumthin hahahah...mines is a lil bit more sloppy than everyone elses (Im not really a Electrical tape whiz like you) but it served its purpose...



I used cables from my OG Xbox for the tx and rx cables that go directly into the port that connects to the drive.

FYI I used my Xbox as the power supply just cuz I needed to do this quickly for a friend and it worked...

But I think in doing so when I tried to erase the flash it froze my computer and locked up my drive so in turn I had to use iprep v006 and dosflash to get it up and running again

conclusion dont use jungle flasher if you dont fully know what ur doing...

Now cut two more pieces of wire, either from the butchered cable or any wire and splice them into the 3.3v and the ground wire in the cable that you are going to use. You can see from the pic below which wires are which.
Click to expand...
I dont understand what to splice? You said before that the 2 wires put into the empty holes on the cable are going to the rx and tx points on the adapter, so why would we need to splice 2 more cables, and where would they go?

drivembig said:
You will need a standard serial cable for this also.
This goes from the serial to ttl converter to you pc's serial port.
Click to expand...
Where should each connection go? Does the standard go from the serial to pc or does the standard go from drive to adapter?

Here are the Pin connections. Just plug in your cable and the follow the pins to the other side and you will see it.

As I can see this is an old topic, but it would be useful enough.
I tried to read an search dozens of sites to figure out a simple way to give power to dvd from pc. Not found one that exactly explains wich cables of those ten(from xboxdvd) connect to those four from pc, and if required some fuses or other? If you could help me a little and explain I'll be thankful. I managed to do myself an "hardware" to extract the key and worked flawlesly(i used a NPN tranzistor BC547 and worked).
Thanks in advance
Best regards

I read somewhere that if you have a connectivity kit to power your liteon,then all you need to do is solder a piece of wire to a sewing needle,put the needle in the R707 hole,and the other end of the wire on the TX pad.Then open the drive half way,open JF and read the key.Does that seem like it would work?

hello i was just wondering if i can get get a source of 5 volts and ground and to use power a xbox drive
like use a flobby drive power and just use the 5 volts and and ground and remove the try status switch

or am i way out there on this one?
