you are doing something very wrong if your wires are getting hot. check that you are not shorting power to ground.
and are you sure you are connecting the wire to the right place on the dvd drive?
post links to pictures of your setup if you can't work it out

What means "not shorting power to ground" i'm sorry but my english is very bad
However i used:
transistor NPN bc338-25
R 1k
R 10k
i connected the ground between pin 5 on the dvd driver sata power and emitter,
5v between collector-resistor1k and a molex pc
Tx between base-resistor10k and pin 11 on the dvd drive sata power and another wire for connect at Tx the R707 pin on drive
pin 5 of serial port to emitter
pin 2 of serial port to collector
that's all  (IMG:style_emoticons/default/unsure.gif)

i connected pc case and xbox case with a wire

hmm doesn't sound like anything should be getting hot...
but pin 11 is ground on the dvd drive... check the pinout.

probably a good idea to take a picture

i have arduino usb board in hand. is it possible to read the keys using it?

possible, yes. you could program it to read the key and output it by the usb port. but it would be a lot easier to find a pc with a serial connection. or use a usb -> rs232 converter which are about $5 delivered from Dealextreme

pin 11 is Tx no ground and pin 12 is Rx i tested them

maybe you are counting them differently
I was using the pinout on here http://dwl.xbox-scen...-HandC-V1_4.pdf

so have you figured it out? is it working for you?

you are right i'm counting them differently, however i've connected gnd at 5v terrible mistake  (IMG:style_emoticons/default/ph34r.gif) i recheck it over and over again and then... (IMG:style_emoticons/default/rolleyes.gif) i'll test it tonight

new test result in:9
DVD key:
2132154a5s4da5s4d6a5...some numbers...
Seems not a good dvd key!!! ...bad serial port comunication B0 B0 ( or 00 00 some times )

i tried many times with the same error... (IMG:style_emoticons/default/unsure.gif)  help pls!!!

i connected tx in dvd drive right because if i don't connect it as result i have: no comunication with com or something like that

perhaps i put the transistor with collector and emitter in reverse, can be this the problem?

that could be the problem. you may have also damaged the transistor with excessive heat.

you can always test the circuit with a multimeter and a 3 volt battery to emulate  the output from the dvd player. but by the sounds of things, it's working but not reliably, which probably indicates the gain of the transistor is low. so yeah you may have the emitter and collector reversed.
it could also be that your serial port doesn't like the non negative voltages, so if the above doesn't work try making the circuit from the uc hobby page.

what i'd see from this test? i have to power up Tx with 3v and see the response from Rx serial port?
how i can see if the transistor was damaged?

perhaps i found the problem, when i open the tray and then push it in half way, then i shut down the power of xbox, then power up pc and then in dos power up again xbox360 with sata and rs232 cable already connected into pc with dvd tray already open in half way, could be this the problem?

basically you power the circuit with 5v as you would when using it. then you put a multimeter on the serial connector and apply 3v to the tx input and see what the multimeter reads, it should read 0v when the 3v is applied and 5v when there is no input.

the order you do things is quite important. see the origional post for the order i used to get it working.
I found that if you have the serial connected to the Tx pin on the dvd drive while booting, it never works. i only connect the serial just  before i press enter to execute dvdkey.
also try powering up the xbox at the same time as the pc

[emawind84]

I've the key!!!  (IMG:style_emoticons/default/tongue.gif)
steps:
-power up xbox360
-open tray dvd drive
-open pin 9
-push tray at half way with green led on xbox flash
-power down xbox360
-connect serial to pc
-connect Tx of rs232 at pin 2 on DVD power connector ( using the pinout here this http://dwl.xbox-scene.com/tutorial/Xbox_360-HandC-V1_4.pdf )
-power up PC
-power up xbox360
-in dos connect sata cable
-dosflash and take address
-connect Tx of rs232 ( another wire ) on R707 in the hole on dvd drive ( not need to solder on drive )
-dvdkey address
-that's all  (IMG:style_emoticons/default/laugh.gif)

thanks yaywoop for your help

[psykiller]

can i use old executer connectivity kit for powering the drive? and computer case for grounding the drive?

can we use maximus xtractor reader software to read the keys?

thanks in advance.
