First time builder, a few questions about matrix board layout and wiring technique

just a few quick questions about wiring the RB and LB and stick on a matrix wireless PCB xbox 360 controller.

first off ive successfully duped the ABXY buttons and the xbox guide and start, but im having trouble locating the correct points for the LB and RB solder points (im only using a 6 button layout and i dont really want to mess with the triggers).

also i got my arcade stick, Seimitsu LS-40-01 in the mail the other day and it has 5 wires, i understand one is for ground and im going to do a direct connection to the D-pad but i dont understand where the 5th wire goes in terms of ground.

this may or may not make much sense but any answers are greatly appreciated

guides ive been following:

Wireless Matrix Controller Button / Trigger Solder Points - Scenyx Entertainment Community
Xbox 360 Wireless Arcade Controller Tutorial - Revised - Scenyx Entertainment Community

if there isnt enough information about my situation listed here just tell me and il post pics of what my PCB currently looks like.

Well I don’t know what you mean saying cannot find LB and RB.
They are labeled in the pictures.

The Signal will be the top right points.
Looking at the back of the PCB, you see four solder points that make the LB and RB.

Now, the PCB is not Common Ground.
So you cannot do a Daisy-chain.

This means you cannot use your Wire Harness for LS-40-01.
To use your Joystick for this PCB, you will have to modify it.
You will have to cut the Ground Trace of Joystick PCB.
Or remove the Joystick PCB and use Microswitch.

Idea shown here using Sanwa JLF as example.

Here is the PCB you have.

See all the colors?
Each thing has a color.
Some share the same color.
That means like colors can share the Common Line.

Don’t know if you understand.
So I suggest you use two wires for each Button and each Direction.

So where does the Ground of your Wire Harness go?
Nowhere it will go; you will not use it, unless you do as above in link shown with JLF.
Here is shown using Wire Harness with LS-56-01 what I’m saying; apply same to LS-40-01.

One wire for Signal, and one wire for “Ground” (it not a real Ground).
Each Button or Direction will have two wires, so you will have twenty-six wires total.

thanks for your reply. i understand what you are saying but how can i use two wires each direction for the joystick when the stick only has 5 wires output?

disregard this, didn’t see the last picture. its all very confusing atm but il defiantly be able to work it out from the information supplied, thanks heaps

I showed you in my Post.

The colored circles are the “Ground” (not a real Ground).
Each colored letter can share the same colored “Ground.”

But it that does not make sense to you, then I suggest soldering two wires for each Arcade Stick Input.
One for Signal, one for “Ground.”

The point directly across from each Signal is the "Ground."
Example of “Ground” across each Signal is shown in colored circles.
Now imagine each Signal having a colored circle directly across from each.

thanks heaps, i think it all just clicked for me. Going to attempt to do this now

does it matter which colors i connect to each direction? is there a specific for each or can any of the colors go on any terminal

oh and its an LS-040 does that change anything?

My picture shows which color wire of Wire Harness goes to which Microswitch.
So solder accordingly to match the Microswitch to the Directional.

Directions depend on how you orient the Joystick.

My picture shows to cut only three spots on the Joystick PCB.
Do not cut spots that are not marked.
It has to be done shown to work.

The original Ground wire of Wire Harness is used for the Microswitch with red dot.
So do not cut anywhere near the red dot.

here is my pcb for the Seimitsu LS-40-01. No clue which lines on the pcb to cut or which of the 8 points i should solder or what color they would correspond to.

if the color layouts in regards to corners are the same as the above pic then i only really need to know which lines. thanks heaps in advance.http://img688.imageshack.us/img688/2305/aracdepcb.jpg

also, last terrible newbie and frustrating question. where are the “ground” terminals for each of the bumpers located?

Ground is the Trace that touches all four Microswitches.
You can follow.

Do not cut the Trace to the one that goes to first Microswitch it touch.
Since you will be using that.

can you just draw lines over which to cut? ive looked everywhere for a guide and dont fully understand what you have put forward. im a complete noob at this stuff and im helping someone else

correct?

The colors are right.
But the cuts are wrong.
Move every cut one Microswitch over.

I told you not to cut at where the Ground Trace touches its first Microswitch.
That would be the one marked Green.

I know my second Post above says different.
But that is for LS-56-01.

My first Post above says what this Post is saying.

It might be simpler to just solder directly to the microswitch points and forget about the wire harness altogether. Then you could grind away all the traces without worry.

itl look like this?

what should i grind the traces with?

If you doing rtdzign say, then yes.

I also told you that option.
But for some reason, you wanted the way with Wire Harness.

Remove the entire PCB if you do not want to grind.
Which I also told you above.

to use the VIAs on the PCB to i just solder a wire to each point shown on that xbox-scene link exactly the same as a button rep?

Yes.

You do not have to solder to the vias though.
Just solder to as shown here.

Scrape lightly to remove the black stuff.
Then solder to the copper revealed.

one of the copper pads came off on up and one on left so i have no choice but the vias
