Hahaha this is fantastic. Maximus is gonna have some sleepless nights over this one.

You can build a real RS232 with maxim chip for free as-well. The maxim website (http://www.maxim-ic.com/) gives out free samples of the maxim3232 chip. They take about 2-3 weeks to arrive. All you need is five 0.1uf capicators, a female serial cable, and this diagram below. Cheers.

I guess you can call this how to dump the lite on key for free part 2 eh yaywoop?

well your computer is already grounded. the issue is if the dvd drive is sharing the same ground as the case. if you are powering the drive from the pc you don't have to worry about the grounding clip.
if you are powering the dvd drive from the xbox, which is not grounded, you need to use the grounding clip.

an ungrounded xbox case  can have very large voltages with reference to ground which could fry your serial port.

I knew it could be Done!! Well Done m8.
For us less Tech, can you supply any codes for the NPN transistor? I have an old power supply here, seems to have loads on it. After taking two off there is a code on it stating C945 - 42E on it. Another i took of elsewere, states C331. All help is much Appreciated m8..

Many thxs
Dogz;)

The C945 is a 2SC945 and the C331 a 2SC331. Do a google for data sheet with pinout.

Yea, and so? U tell us plz.. R they ok. He states Any.. Well Dont seem that way. Only clearing things b4 someone goes BANG!

I was cable scene, most of the gear here talks RX + TX to Serial, but with MAX233 and Just Serial 2 Scart no chips, also MAX232CPE, ALL TX And RX. they May work also? Who knows..
 
SO Clearing Things up, not a crime..

Thx
Dogz;)

WELL COME ON! So called Xbox-Scene!!!
Such Cool Mods and Memz (Counters) But (Ruling out real People That Wanna Learn)... Not seen anything from ya all in this thread, So called Hackers! DO the Job as stated, and c If the "Simple Things Work"? Or are you all working 4 the Kits and getting little pennies to stay alive... (Bring bk real Peeps) I done it, and ALL WAS 4 FREE 2 (With Instructions!!) 1998-2005...... F>U>A

DOgz......

I don't really understand what you are trying to say there.
yes any npn transistor can be used. as long as you know or can work out the pinout.

yeah if the single transistor doesn't work for you you could use that.
I also made a single transistor converter which converts it to +/- 3V which should work with more serial ports.

100% solderless.

Gonna try it myself hopefully tomorrow, but i'm pretty sure that you can join that 2 spots drwaing a line with a simple graphite pencil.

And i guess if you don't even have a soldering iron on ur home, for less than $10 you can have a small bread board, 1 transistor or 2 (buy a backup just in case), the resistors and some cable for a 100% solderless solution. Not even the db9 is required, since it's only 2 pins, you can just stick the wire and put some tape while working. Even the ground wire can be a bridge between the pin and the case (asuming that you are getting the +5V from one of ur molex or anywhere in ur PC PSU).

Too bad i bought my RS232 yesterday for $3 at my local store.

yaywoop,

Nice try !  But is that guide completely solderless ?  It sure doesnt look so and still looks complicated !!?

Anyway, i rather will not do that this way.. It seems allot can go wrong whit the drive just connecting those parts to eachother even before i could get out the drive key for the FIRST time !!  It looks fun indeed , but i rather not want to damage my 3 weeks old box render it useless whitout the key !!


rgds,

i've problem, when i connect serial port into pc and power up my xbox with driver connected to it after some times pop up 3 red led and the serial's wire is hot, first that pop up the 3 red led i can do Dosflash in dos and the pc see my driver but when i try dvdkey it's result in output: d800 or something else and anything else, but after 2minutes pop up 3 red led again... i don't know where i'm wrong, i checked out my circuit in all parts and is all right, perhaps is my transistor too light? or perhaps i inverted connector with emitter?  
i connected rs232's gnd on power dvd drive and 5v on a molex in pc ( tried to connect it on power dvd driver too )

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

baltazor,

I didn't say you didn't have to solder, you still have to solder the converter together. but you don't have to solder anything in the dvd drive, which you could screw up easily if you have little experience soldering.

this is not complicated! it is as simple a DIY solution you will get! 3 components!
if you follow the instructions and do some reading on how transistors work it should be very straight forward.

Hey yaywoop,

This is great! Only thing I don't understand is why the transistor used is NPN. In this UC hobby schematic they show a PNP connected to the RX said of the PC? Can you help us understand how this works?

well you can actually use either NPN or PNP for this converter. but NPN are more common so i made th circuit to use them.

in my schematic, the transistor is acting as a switch. when there is no input, the collector is pulled to 5V by the 1k resistor.
when there is an input voltage, current flows through the base and turns the transistor on, which pulls the coollector low.

the uc hobby schematic has a negative supply which is supplied by the serial port. (rs232 specifies a negative voltage for 1 and a positive voltage for 0, so the negative voltage means it should work with all serial ports just like a max232 chip would)
when the input is high, no current flows through the base, and the output is pulled low by the negative supply.
when the input is low, the transistor is swiched on and the output is pulled high
this is the exact circuit i also tried. it had trouble with the 3V signals from the dvd drive, so i had to run it off 3V for Vcc to get it working. which also meant that it only outputted +/- 3V instead of the standard +/- 12V.. which might have been trouble.

if my one  doesn't work for you, you can try the uC hobby circuit. but you can 'status' and 'rs232 to ttl' sections. they are not needed.
