Help With Analogs and LEDs

MonMotha:

The XB360 uses USB for its controllers (and, sadly, will pretty much disown any "standard" USB gamepad), so you can just grab 5V from the VBUS connection in there.  It'll only have power when the device is plugged in and powered up.  Use LEDs with integral resistors for 5V or size your resistors for 5V, and you're good.  Shouldn't be too hard to find and tack down to that 5V line.  No tiny iron or AWG30 wire needed.

Donkbaca:

The 5v on usb is a constant 5v, even when the xbox is off.  At least on the pads I hacked


MonMotha:

Gah, I guess everybody wants to charge batteries and do remote wake-up these days.  That's...fricking annoying.

There are various tricks to make the buttons light up when pressed if you prefer that behavior.  The "easiest" solution involves a bunch of diodes, but there are other options, many involving a single transistor per lamp.

If you can find some sort of indicator on the controller as to whether it's "powered up" or not, you can use that as a signal to switch the lights on/off.  A smart strip seems like total overkill but is likely to work given how much of a power hog the XB360 is.

Of course, you could always just unplug the darned thing when not using it.  Seems like the easiest option, to me :)
