Xbox 360 controller hack problem - Looks like 3K are pressed

Tech Talk

Hi guys!

I have been reading through SRK a while now, and I am finishing my madcatz TE PS3/360 mod. Originally the stick is for PS3, I am adding a wireless controller to it.
Mainly because I had a spare wireless controller and I wanted to start right away.

I am running into one problem. Kicks are not working.
At first I thought it was a soldering issue with 3K (LT), so I undid the soldering. Now both LT and RT are clean. The thing is: when I go into USFIV practice mode it will show like LT is pressed. If I manually test LT it will signal only l.k and m.k (no h.k). When I try manually RT it gives no signal to the console. So it looks like there is a short in the RT, but it is not connected to any other wire.

Any idea? I ended up messing up the RT trail, so I will have to find another way to connect to RT. :disappointed:

Did you refer to this:

You might need to invert the triggers.

What Controller you are using for the PCB? I assume its the MS brand one but I ask and be sure.

And can you provide photos of your work? Maybe we could spot something you didn’t

It is M$, and looks like the early one.

I just uploaded the pictures to my flickr account: https://www.flickr.com/photos/leokorndorfer/sets/72157651692586808/
The last picture is just to prove there is no short between the RT and GND.

Thanks guys!

I know this PCB looks horrible, but know that this is my first mod ever. I probably used to mush hot glue also. :wink:

Your triggers need to be inverted

Hi Yenjoi, can you give a bit more detail or point somewhere I can find the information on what/how trigger invert?

Thanks!

ok, just to double check what I learned from here: http://forums.xbox-scene.com/index.php?/topic/581887-wireless-matrix-controller-button-trigger-solder-points/

I should add a 10k resistor between RT1 and RT3, LT1 and LT3. That’s it?

This is trigger inversion:

So basically I will just put a resistor there for now, while I don’t get the inverter chip.
But now I messed up the RT hole, the copper fell out and it broke from the trail. You can kind of see the before here: https://www.flickr.com/photos/leokorndorfer/16605384593/in/set-72157651692586808

When I took off the wire I somehow pulled out the copper from the RT hole. Now where can I with RT trail?
Something similar happened with “left”. As the area was too small I acidentally removed the copper from the dpad contact, then found the tiny hole the trail was going to, and welded there.
