Worked on some xbox hacking gear. I tried to see if I could source parts and produce a cheaper version of other peoples hardware but it didn't fair to well.
Basically it is a power supply to power the xbox DVD drive in order to flash it (you can use the console to power it but you risk getting flagged and possibly banned).
You need to supply 3.3v, 5v and 12v to the dvd drive. I would of used a molex connector to bring in 12v and 5v and used a lm1117n33 regulator to drop the 5v to 3.3v. From there you can simply hook the voltages up the proper pins on the xbox header connector, although I wanted to include a dvd tray ejector switch and a MODE-B switch.
I screwed up on the switches they are wired in wrong, but meh. After I realized it would cost me around $11-$14 per board (I have to make 10 if I'm going to ask a pcb fab shop to print them for me) and a regular board I can buy online with the same features is only $15-$20. So not only would I be eating the cost for the 9 other boards, I wouldn't be saving a hell of allot of money.
Now don't get this wrong, I was trying to make this look pretty. If I wanted to I could hack together the adapter with the voltages, not include the extra features, and throw it on a piece of protoboard for less than 5$, but I wanted something pretty :<
Here's a broken schematic and a half done PCB trace.
edit:: Waiting for my parts from sparkfun, they should be here in the next few days. Then I can start really working on my main project.
