Controller Technic / Re: Analogue twinsticks
« Last post by RDC on Today at 06:40:02 am »
Do you actually need the Analog function? As in there are some parts in the game where you actually have to press the stick only part way to do this or that?

If not, you can just wire the switches of the Dual Stick up to the POTs of whatever controller you're wanting to use (6 wires) and off you can go. It will only work Digital, aka full blast, in whatever direction the stick is pressed, but if the Analog feature isn't really necessary, that's one solution, albeit not really an Analog twinstick then.

If the Analog must be kept, I'm sure we can figure out something.

Got everything working like a charm. Thanks dude.

I put everything on my github so anyone can have a Wireless 3D controller, via the Dual Shock 4. Any capable person could edit the code and use any controller supported by the USB Shield library.

I'll second that. I've been running 100V devices on 110V for decades with no ill results.

You're right Japan is 100V (my mistake there). 10% difference should be fine though, so long as you're not running a high power device like a hair dryer or kettle.

I recalled my PSU recently, and referred to the schematic here : http://nfggames.com/X68000/Schematics/PSU/X68000_EXPERT_PSU_Schematics_v1.5.pdf

The 110V output appears to be connected straight through, and should not put any load on the PSU at all. I don't think you need to worry about the x68k PSU in this case. I'd be more worried about whether your step-down transformer can handle it (if you're in a 220V area).

You mean 100V output? I have already japanese step-down transformer coming soon which is capable of 1000Watt. It's surprising how many are refering to 110V transformers while 100V is needed. Doesn't 110V put too much stress on 100V device?

It's quite handy for external drives, such as CF/MO/CD-ROM

I was thinking to use my Famicom power supply on it when not using X68000.

I bought the pots but never installed them, I'll dive back in soon

What I have done is get the analog Arcade naomi Joysticks and put the xbox 360 pots in sequence with the existing pots on the naomi sticks, it works, but theres issues I don't know exactly how to describe, mostly in the manner of actuation without ever putting the joystick into motion... Im locked in to seeing the project through, just NEED MORE TIME TO MYSELF! LOL

I've started working on this project again, because Nex Machina is amazing.  It was sort of like starting over because (holy shit) it's been eight years since I did most of my hacking at it before...

Here's what I've done this time, using a Hori 360 pad. 

1. Wired it up direct, each pot a direct replacement for one in the pad.  It works, but movement range is restricted to about 50% of the original.  It doesn't go more than two thirds of the way to max on any axis.  As far as Nex Machina is concerned, this means I can shoot in all directions, but the player moves very slowly.  It is therefore critical that full range be restored.

2. Tried the 1k resistors, which made it much worse.  Movement was limited to little more than the deadzone.

3. The Hori pots run on 1.5V, so I shoved 5V from the USB cable into it instead.  This maxed it out, as you can imagine, but the full stick range was subsequently unable to move it very far from the diagonal corner it'd wedged itself into.  ;)

The issue is that the Sega sticks seem to use a linear 0-10k range for the full motion of the pot, but the Hori is limited to about 60 degrees move movement around the axis, but still goes 0-10k.

So the Sega stick gets ~2.5-5k range, far less than the Hori pad requires.

Before I go all DIY and create a whole new USB interface, I'm hoping to figure out a way to connect the Sega sticks to the Hori pad, thereby preserving both PC and X360 use.

Anyone else get this working in the last decade?  ;)
