Stick Adapter Mod SAM finished - Common Ground Mod

Hi,

I've assembled my common ground mod. Here're the pics. This circuit allows you to connect Seimitsu sticks like 32-01 or Sanwa JLF to non common ground PCBs.



Here's an closeup. Just connect the stick and PCB with standard delivered cables.



Yo, connected to a LS32-01



I've some more left: First com first serve

Say hello to SAM, TIM, LIM, SUC and the LiPo USB Charger

Hi out there,

yesterday I finally received my own bunch of self-made PCBs. Here they are:

SAM for xbox360 and others.



SAM is Stick Adapter MOD for Sanwa JLF and Seimitsu LS32-0 like sticks.
This is the solution for all xbox360 PCB. Since almost all known xbox360 pads are not common ground it's difficult to assemble xbox360 with premium stick like the Sanwa JLF or Semitsu LS32-01. This widley used sticks have a common ground 5 pin connector and are not compatible to the most xbox360 controllers. This adapter solves this problem.

LIM and TIM


LIM is a Led Inverter Mod. To separate your PCB and your LED Mods LIM can be used to secure your PCB. Bullet proof led mods can be also done with this PCB.

TIM stands for Trigger Inverter Mod. Some xbox360 Pads uses no common signals (high instead of low) for the trigger. Due to this the trigger can't be used in some xbox360 pads. TIM solves this issue.

LIPO-USB-Charger



Led Mods or circuits needs external power resources. With this PCB you can use LiPo batteries used in handys or digital cameras in your mods. Up time increases and your LiPo batteries are recharged via USB.

SUC


But you need 5V in your circuits. Of course you do! Here is SUC. SUC takes 1 AA (or more) and outputs 5V. SUC works of course with accumulator batteries and has built in protection against discharging.

All PCB have to assembled with parts. Contact me if your interested in this stuff.

Bye,

Ben

Tutorial: Assembling Sanwa Stick Adapter (CG Mod)

Hi,

many questions arose to the sanwa stick adapter. So here's a tutorial about assembling the adapter with many pics.



Step 1: Soldier the pcb. Locate the GND and Signals of the directions with a multimeter. I've marked the GND Points with a pencil. Summarizing there're 8 cables going from the PCB:

PCB 1 - Signal Up - White
PCB 2 - GND Up - Black
PCB 3 - Signal Down - Green
PCB 4 - GND Down - Blue
PCB 5 - Signal Left - Purple
PCB 6 - GND Left - Grey
PCB 7 - Signal Right - Orange
PCB 8 - GND Right - Yellow

Then on right hand side USB VSS and USB GND

9 - USB VSS - RED
10 - USB GND - BLACK



Step 2: Assemble 4 resistors and optocoppler on breadbord

Pin 1 - 1K Ohm - USB VSS
Pin 3 - 1K Ohm - USB VSS
Pin 5 - 1 K Ohm - USB VSS
Pin 7 - 1 K Ohm - USB VSS

Step 3: Connect cable to breadboard



Pin 16- PCB 7 - Signal Right - Orange
Pin 15 - PCB 8 - GND Right - Yellow
Pin 14 - PCB 3 - Signal Down - Green
Pin 13 - PCB 4 - GND Down - Blue
Pin 12 - PCB 5 - Signal Left - Purple
Pin 11 - PCB 6 - GND Left - Grey
Pin 10 - PCB 1 - Signal Up - White
Pin 9 - PCB 2 - GND Up - Black

Pin 2 - Black - Right
Pin 4 - White - Down
Pin 6 - Grey - Left
Pin 8 - Purple - Up

Cables are then connected to luster terminal (right hand side)

Port 1 - Black - Right
Port 2 - White - Down
Port 3 - Grey - Left
Port 4 - Purple - Up
Port 5 - BLACK thick - USB GND

Use this connector for the Sanwa Stick Cable.

Try to read the schematic




Of course one can use this adapter to make a dual pcb mod. Though set all needed signal to cg which are not cg.

New Stick Projects: Mad World and Final Showdown

So,

yesterday i finished the stick for Jens. Building this stick I've learned that plexi is sometimes sad to work with. If somebody has hints for scratch resistant plexi please leave a comment.

Second: the measurements are great! Next sticks for myself will've this measurement too.

Third: Mounting issues about countersinking and threaded caps.

But now to two new sticks:

- Mad World
- Final Showdown

We're starting with the parts and soldiering job.



Good part choice: Sanwa Sticks, Balltops in black and red. Functional Buttons in red and black from sanwa, too. Play Button are clear pushbuttons from seimitsu, really beautiful ones.



Heres the soldiering for the wireless pad. Commong Ground for the sanwa stick, headset support and tailored power pack on back side. Recharging will be done via USB connector.

Case pics will follow soon. Aaaand watch out for the really great artworks.... :) (cliffhanger done!)

common ground mod for wireless xbox360 pad

Hi,

here's the a common ground mod for wireless xbox360 pad. Thus now it's possible to connect Sanwa or Seimitsu 5 pin connector sticks without destroying the PCB. There exists even videos how to destroy your joystick pcb by cutting traces. There's no need for this action. ;)

Adjust the resistors to 220 ohm and enjoy common ground xbox360 wireless pads.

Common Ground Mod with Optocopplers

Hi,

common ground mod is used for various topics:

- connecting sanwa or seimitsu joysticks with 5 pin connector
- upcb piggyback
- dual pcb mods
- easy wiring



16 signals version


4 Signals Version

Common ground Mod with analog switch

This common ground mod are uses in arcade stick building for several reasons:

- keep the wiring easy (daisy chain for ground)
- dual PCB mod
- using the standard 5 pin connectors for sticks like sanwa jlf and seimitsu LS32-02
- connecting vintage joysticks like competition pro for sensible soccer ;)

This is just another approach comparing to the optocoppler approach. Optocoppler a little bit more expensive. Therefore wiring is here mor complex and more parts are used.

Layout Description:

Joystick in general have the states disconnected (undefined) and active low. To define a active high for the inverter pull-up resistors (R1 - R4) are used when stick is disconnected.

When joystick is moved to one direction signal is active low. Inverter changes it to active high. Active High is needed because 4066 switches only on Active High. The output pins are enabled and activate corresponding button on the xbox360 gamepad.

Common Ground Stick Seimitsu LS32-01 connected to non common ground xbox360 pad (Big Ben)

Okay,

when building arcade sticks common ground game pads are used for several reasons. One reason is to build up dual PCB in one arcade stick. Due to this for example PS2 and xbox360 can be connected to the stick. Next reason to use common ground pads is to connect common ground joysticks like seimitsu LS32-01 and Sanwa JLF sticks. These use common ground pcb interfaces. Also UPCB needs xbox360 common ground pads for piggyback.

Since there nearly exists no more common ground pads in europe I've found a solution to make out of non common ground pads common ground ones. In the prior post I've shown a scetch. No I soldiered a prototype on breadboard. The solution is cheap and needs only few part. Per signal you need one optocoppler and one resistor, thats all.

I'm using in the pics 1k ohm resistors and 4N 27 Optocopplers .



Here's the padhack connected to the optocopplers on the bread board. Every pad has two wires to the optocoppler ICs. Pad used is Big Ben xbox360 game pad.



Close-up: The thick wires goes to a seimitsu LS32-01 Stick which is common ground.



Yeah, it works fine :-)

Pin1 -> resistor 1k Ohm -> 5V USB
Pin 2 -> Signal Arcade Stick, i.E. Direction Down
Pin3 -> Not Connected
Pin4 -> GND line from gamepad for direction down
Pin 5 -> Signal line from gamepad for direction down
Pin 6 -> Not Connected

Common Ground Stick like Sanwa or Seimitsu LS32-01 connected to non common ground xbox360 pad

Hi,

several people ask me how to connect non common ground xbox360 pad (original ms ones) to common ground sanwa JLF or seimitsu LS32-01 sticks. Here's a scetch for an easy strip board solution. It makes use of optocopplers. Solution is based on this blogentry of gtpunch. Thanks mate.

The IC used is 4 in 1 optocoppler chip. Chip name in the legend is order name for reichelt.de.
