"My biggest dream in life? To build black plywood habitrails"
lol, I was thinking the same thing as soon as I read that!
Except, of course, that Kenny's would have l.e.d.'s and be called a "princess wheel" and therefore could never be confused with SNK's proto
OT - although not for me, it's a great piece of info to release - thanks Tony!![]()

This is the only optical one they have. Quite expensive. However, hacking something like this is possible. I have some happ trackwheel stuff laying around that is basically the same thing. Once I get the parts in, I'll see how inexpensive we can get a wheel working.
Personally, my goal is to get one of these working on it. http://www.ultimarc.com/SpinTrak.html.
EDIT:
Please correct me if I'm wrong Tony. You arent hacking anything on the actual optical encoder are you, but pulling from the LR outputs of the encoder right?

I am very interested in this, if someone can put together a complete parts list to build one of these in a box with a Neo controller input, I'd be in hog heaven.
Thinking of some wheels that might work:
Pole Position games
Off Road
Think of any game that you could spin the wheel and it would keep spinning. Those are what you need to look for. You can get those cheap on ebay, but no idea if the encoders are working or not. So something similar to the link I posted earlier could replace the old encoder.
Awesome, dude.
Now my dream is a bit nearer, a true driving game on the neo "ala outrun" with a steering wheel.

very nice Tony!

The encoder I have in mind is like this: Incremental rotary encoder
Just so we're on the same page.
By "analog" I mean you don't at any point use a microcontroller, CPU etc. Just logic.

that is exactly the type, quadrature encoding system. Arkanoid, Pole Position, Top Speed use them.
NTM: there is no modification to the steering wheel assembly. The two photocell outputs simply go to the board inputs.
As an aside, granted the first licensing, a kewl member on here will be making and hopefully selling the boards. Plug and play fun.

I'm gonna have to look into how the flip-flop determines output pulse length, my digital logic skills are not very high so it's voodoo to me how you count pulses from the sensors in one direction and output that to left/right for a length of time depending on how long you're spinning for. Gonna have to get out a logic simulator and some notebook paper at some point.
This actually has implications for another project I've fiddled with off and on, I was thinking of using a microcontroller to decode quadrature encoder sensor outputs to button presses (variable length or not) but that's such a hackish and overkill solution..
edit: Misunderstood I think, so you don't send a single pulse of a length, but a bunch of small ones for a period of time? Makes a little more sense to me. Flipflops are still voodoo to me, so they're simultaneously a memory of the last sensor state and a state table to determine direction based on the next state? We did one lab with them in digital logic but it was way simpler than that.

the flip flop only steers for left and right. The one shot 74LS123 is what enables the actual joystick press through the AND gates. With too fast a time, it would make the control stutters so the 12K and 1K was the change to make it work out nicely.
and if you can use it to have into something different with ideas form it, please do. You got my respect on here for many years and am pleased to return the favor.

Edited my above post a bit but thanks for the info
FYI the project is adapting a PS2 beatmania IIDXcontroller to USB, it's a music game which has a turntable. The turntable uses a quatrature encoder, and some chip in the controller takes the sensor output and determines direction from it, then outputs left or right to the PS2. Unfortunately that chip that does that is also the main "talk to PS2" chip under a glop-top. So if I were to interface it to USB I would need to do the quadrature sensors -> direction handling on my own.
There's homebrew beatmania IIDX recrations on PC and the old "beatmania" (non-IIDX) series is emulated well in MAME, but using a PS2->USB converter introduces lag, I would rather natively interface it to USB by wiring the controller's buttons and turntable to a USB gamepad.

I'm not an EE but I was thinking a large capacitor to keep the output high for a while, while it waits for the next pulse. Just an idea after one minute of thinking.
It doesn't look like I could shove the circuit as-is into my idea and have it work exactly like I want, it'd take tweaking, but the groundwork is laid out.

This is really awesome! Thanks, Tony. Nice to see it got stickied at the top.
awesome Tony! Thanks for sharing
I clearly remember a neo drift out cab back in the time, here in Italy, using one of those steering wheels (spinning endlessy in both directions)... it was fun and stylish...![]()
anyone have pics of the cab?

Fucking awesome thread!
This is absolutely made of win. Thanks, Tony!
As I said in chat Tony, this is really cool! I really want to try the wheel out with Neo DriftOut; it would seriously never come out of the cab![]()
