So I'm kind of new to electronics but I understand a fair bit. The power button he solders in connects the board directly to the ground through the grounding pad and one of pins for the port to the button. This bypasses the capacitive touch sensor on the 360 slim and allows you to turn the console on with a physical button.

How exactly is that happening?

How does capacitive touch work?

Isn't this the same as connecting the board->ground and pin->button->ground? As I understand, electricity takes the path of least resistance so both lines will flow to the ground, or is it different in circuitry than houses?

If so, could I wire to use a 2 pin mechanical keyboard button for the power button to connect the pin to the ground and just bar fuse the board and ground?

The touch pads have very easy to follow traces that connect 5:5 to the port I understand that capacitive touch is different somehow, but couldn't you just solder a button to the contacts on the port?

Any help would be appreciated, I'm working on a total overhaul of my old 360 slim and this is going to be a big part of the aesthetics when I'm done. I'd very much like to get a good tactile button for the power and eject.
