Nah, that won’t work. Gotta be a common ground.
3.3+ volt is for people wiring a Happ/IL joystick to a psx controller.
Your using a Hrap3 and i’m assuming your not switching your stick parts out so you don’t not need to worry about.
If you ever swap out for a sanwa or a seimitsu stick your never going to have to worry about wiring to a 3.3/5+ volt. However if you decide to use a Happ/IL your gonna need to use the 3.3+ volt(make sure to follow the various srk instructions on using a psx pad to power em). Likewise if your using some unknown stick, check to see if it requires 3.3/5+ volt to work.
Noob question but when hacking a PSone DS pad do I need second analog pc or can I take that off along with the rumble motors?
cool. thx for the reply. Should be an easy enough mod then.
^ ^ ^
Just a few quick add-ons to Twinniss’ response if you’re curious to know more…
It’s specifically the Perfect 360 model joystick (once made by Wico, now made by Happ) he’s referring to that requires the +3.3v line. Technically, it requires +5v but 3.3 is usually enough. The same applies to virtually any optical joystick, though other brands/types are hard to find these days; the Sanwa Flash is out of print, and ASCII made a respectable clone of it that can only be obtained by pulling it out of their premade controllers.
Optical sticks use the… uhh, “volt line” (I don’t think this is the proper term) to power their little brain and eyes; it literally sees where the joystick is positioned and relays the information as though switches were being triggered to cause functions. Basically it’s using fancy-ass techno stuff to simulate (well, surpass is the goal) actual physical microswitches.
A normal (microswitch) joystick doesn’t require the volt line at all. For the record, the line doesn’t need to be used for the controller to work, you can just not hook anything up to it.
I believe that you can actually use the volt line for just about anything though, since it’s really just a power supply. You could pimp out your stick with some little LED lights. I think one dude put up a small LCD display that does scrolling-marquee text, pretty ballin’. I might hook up dim-glow lights and a computer fan to mine so it will soften my skin and blow my hair around while I play, like a glamour photo shoot. Yea I’ve got game like that, don’t worry about it.
ROFL 
I was wondering why I didn’t need it for my HAPP competition modded stick, thanks for clearing that up, haha :rolleyes:
BTW, for the HAPP 360, since it’s optical, can you adjust the distance where it detects a direction so that you move the stick even less than say a sanwa stick to hit points, thus making it less effort to pull off moves? just wondering…
Also, any advice on how to go about adding the ps1 pad connections to the buttons and JLF? Should I get new QC’s and join the wires from the HRAP3 pcb and ps1 pcb then connect it to the buttons? As for the JLF, i’m guessing it’s using the 5-wire universal cable. How should I connect the new wires from the ps1 pcb to this? Any help would be greatly appreicated.
it is strongly suggested that you keep the analogs on. otherwise your gonna have to solder some resistors. Just remove the thumbstick part. rumble is okay to remove as well as the triggers(you even get lil holes(makes soldering really easy) to slip a wire in for triggers and a ground)
oh didn’t know it was specifically for the p360 and optical sticks
just solder directly on to them. If you have room and wanna be more clean(and make connections a little easier to change around) you can add a terminal strip in between the buttons/stick and the pcb
Will someone just sell me an arcade stick for xbox 360
I know bout them
I heard of them but idont like their sticks, i like the smooth sleek ones i see people making around here
Well, you weren’t being very specific, now were you? Go to Trading Outlet.
So if I’m looking for a cheap 360 controller to piggyback onto the UPCB, anyone have a suggestion? Or am I just better off doing my “buy from store, take apart, use multimeter, FAILS, reassemble, attempt to return” routine? I can completely understand how this sort of thing would not only be hard to catalog, but hard to make use out of the information as well.
I had a guy use that recently at it works just fine. Same on that’s in the Instructable.
Hi to all
Anyone known if its possible to Hack the first PSX controllers? I find one store to have this type of controllers for only 2$ approx, i like to known if this controllers have compatibility for PS2, PS3, and other console adapters.
Anyone built his stick whit this PCB?

Thanks!
You should check out the ‘padhacking’ thread. I hear they deal with hacking up old pads for use in sticks. You should read it in case someone else may have used one of those.

I’m also curious about those PS1 pads.
There’s all kinds of crap about hacking the psx pads in the first post and throughout this thread, guys.
Anyone have approximate size specs for a pcb from a regular or madcatz wired 360 pad? I’m using the giant madcatz arcade stick pcb right now, must be like 4" x 3", and I wanna use something smaller in my next sticks.
Anyone try the Alienware PS2/PC dual compatible controllers? I heard some things about missed inputs and such. Is this true? I took one apart and they’re easy enough to hack but is the PCB reliable?
Be a great way to get around finding a converter for PC for your playstation joysticks. They cost around $30+tax new.
The first post only talks about dualshocks, and the thread is 64 pages long so I was just hoping for a quick “it’s easy” or “it’s a pain in the ass, don’t bother.” 
Hey I’ve read this entire thread
regarding the DS model A
Can someone explain to me where does the other end of the resistor get soldered onto?
I’m electronicly retarded
If you anyone could help me out, I’d appreciate it very much
