2 PCB's in one stick - Possible?

thanks toodles, i guess my brain was too fried to check all the data cables again, the ones going to the cthulu were reversed

I am having the exact same problem. Can anyone shed some light on this?

The 360 side works perfect including the triggers, but the ps2 side won’t work at all.

In this wiring diagram (refer to the orange line), is it okay to split the dedicated home/guide button in which one wire goes to the cthulhu home terminal and the other goes to the guide terminal on the imp?

Im in the process of modding my ps3 TE stick.

I have finished everything but for some reason when i switch to the xbox 360 via the DPDT switch, and check the button configuration through windows, all of my buttons are marked down as being pressed. im really confused as to why this is. ive already tried redoing all of the buttons. i used the solderless trick for them btw

everything on the ps3 side works flawless, but its just when i turn on the 360 portion all of the buttons stay pushed down.

any help would be greatly appreciated

disregard, problem solved

Hey guys im pretty new to the modding scene. I was constantly looking through the thread but i cant seem to find a guide in dual modding a HRAP3+Xbox360(Madcatz)+Imp wiring.

Can anyone point me out? having a hard time finding it

I have a similar problem.

How do you solved it?

Hi, I was wondering if anyone here has a ps3 SE dual modded with a madcatz 360 controller + imp kit. If you do, do you mind posting a picture of the inside of your case? I’d like to see where and how you mounted the 360 PCB.

I am in process of dual modding my 360 TE. New sanwa buttons and JFL stick. I am using a Hori FS3 PCB and I don’t mind having 2 usb cables sticking out. I am about to start wiring them together by using the diagram below.

My question is do I have to connect the Ps3 PCB to the 360 PCB? I’ve read that some have done that, but I’m not sure why, and if I do, where do I wire them together? Never modding a stick before so this is all new to me. I have a diagram of the PS3 PCB here. http://i298.photobucket.com/albums/mm275/mountaindewfkr/FS3PCBLayout.jpg

Thanks for any help.

Please Help me…

ashura- you can use any ground off the PS3 pcb and connect it to any of the 360 grounds. You can either connect the two wires using a terminal strip or soldering the wires together.

I’m have all my parts now, and I just wanted some verification with how i’d wire up the x360 pcb to the cthulhu pcb and then to the imp switch. (I’m fairly sure it’s correct)

here’s a pic:

This is the modchipman pinouts for the screw-in terminals:

RIGHT SIDE TERMINAL (ABXY)

  1. Right Trigger (RT)
  2. Left Trigger (LT)
  3. Right Button (RB)
  4. START
  5. GUIDE/HOME
  6. Y
  7. X
  8. B
  9. A
  10. 5V

LEFT SIDE TERMINAL (Up, Down, etc)

  1. GROUND
  2. BACK
  3. Left Button (LB)
  4. UP
  5. LEFT
  6. RIGHT
  7. DOWN

and here is A-H and 1-9 for the Cthulhu:

A - VCC
B - D-pad Down
C - Ground
D - Select
E - D-pad Right
F - Roundhouse/3rd Kick. Recommend at RB.
G - Fierce/3rd Punch. Recommend LB.
H - Jab/1st Punch.

1 - D-pad Up
2 - 4th Punch. Recommend RT.
3 - D-pad Left
4 - 4th Kick. Recommend LT
5 - Start
6 - 2nd Kick/Forward.
7 - 1st Kick/Short
8 - 2nd Punch/Strong
9 - Home/Guide

The buttons and joystick are going to be hooked directly to the cthulhu’s screw-in terminals.

Is it all good?

OKay thanks, but where is the ground on the 360 PCB?

Alrighty…after much searching and reading, I finally have a breadboard setup for the light-up that I want to add to my new stick…a Cthulhu/MC4716. It looks like I’ll be using a DPDT for switching but there is a mod I’d like to add that I hope someone can help me with. The switch is hidden away on the case, and I would like to use, say a 7segment display showing digit 1 or 2 to indicate which pcb is switched.

I was considering a mux off of D+ from both pcb’s as selectors. Would this be the way to go? If so, which mux would be best suited? Can I do this without worrying about the boards ceasing or frying from too much current? Wiring advice? I know it’s a lot, but help much appreciated:).

Toodles?

Anyone?

:slight_smile:

Easy to do with an Imp involved, since you’ll have access to digital signals indicating which is in use, but you dont have anything like that with a DPDT.

So I take it that means that even though the DPDT is only engaging one set of D-wires, the voltage levels on the D’s of both pads is the same?

So I’m looking at this diagram.

I am using a HSF3 PCB and Madcatz Fightpad PCB (I got it cheap). I’ve sucessfully hacked the fightpad. I plan to dual mod. I also plan to use 2 seperate USB cords. No switches or anything. So I understand I don’t have to put a switch between the data.

I just had some questions.
1.Why do we connect the 5V on the two boards together?
2.Also why do we connect the ground on both the boards together?
3.Also since the buttons and stick are already soldered to the HSF3 PCB and it is common ground, Do I still have to daisy chain the grounds to the Terminal Strip or could I just link any common ground to the strip?

Hey Pocky…

I’m not an expert by any stretch, and the electronics stuff I studied was ages ago, so I may be oversimplifying, but the problem when using two pcb’s where only one is powered, is that the “off” pcb’s “0” states interfere with the “on” pcb’s “1” states, causing transients and unpredictable results, so that in effect, the active board isn’t receiving the signals it should be. The grounds need to be connected together so that both boards reference the same zero voltage, pretty much for the same reason we connect the 5Vs. As for your last question, assuming your buttons are already properly grounded, all you need do is link any point on that ground to the strip, and do the same for the second pcb to the same point on the strip. For all intents and purposes, in a proper common ground circuit, all ground points are already daisy-chained.

Well said.

sorry for quoting an image but can this be done with a psx/ps2 + 360 controller with 1 cable?

I was going to go with the rj45 method since psx isn’t USB but I noticed that this method used a MC Cthulu set up.

would I still go about the same wire up method but use a DPDT switch for the ground and voltage (pin 1 and pin 8 in acceptablerisk tutorial)?

EDIT: Or would I use different pins since I have read that I need to keep ground and 5VC connected to each board.
