I live in the USA and need a few PAL power supplies for any model besides 1.6, I'd take 1 but would buy up to 3 if you have them available. Let me know if you can help!

Picked up another xbox that was sold for parts and untested. Noticed a switch hanging out of the bottom so took a chance. Xbox started up fine and booted up custom bios. Had to remove the motherboard to remove clock capacitor that has visibly failed. Does not appear to be any damage to the traces (version 1.4 or 1.5). Will reinstall the chip after cleaning up the xbox to see what I have. Already downloaded the install instruction that were on another thread.

So my friend and I are trying to replace the front panel LEDs with RGB LEDs using a separate microcontroller. We were able to read the status from the current front panel so we can react to error codes properly, so it isn't just a "dumb" LED replacement with an external controller. Our next goal was to send commands over the SMBus to the Arduino (Nano, ATmega328P) we use to control the RGB LEDs. I customized the XBMC code to send data to the new address I defined for the Arduino, in our case we used 0xE9. Since the Wire library of the Arduino already shifts the bits, we set the Arduino's address to 0xE9 too. The thing is, the Xbox sends the signal, but the Arduino isn't reacting to the given address. We already tried to analyze the signal and we can confirm that there is data being sent through the SMBus. OFC we wired up SDA and SCL correctly, we checked twice and since the logic analyzer is able to sniff data, it should be correct. Has anyone ever tried this yet? I've seen a couple of threads talking about controlling Ambilight over the SMBus but it seems like nobody has tried it yet. I guess we are doing something wrong, but we haven't yet figured out what it is that we are missing. Next thing would be buying a proper logic analyzer, but maybe somebody here has some experience and could lead us in the right direction before we spend the money. Is there any more documentation on the SMBus of the Xbox out there? I've just found the documented stuff on the xboxdevwiki. Thanks in advance!
