I take it this uses SPST momentary switches and the state is held by the logic gates? That being the case where can I jack in LEDs to signal which switch is currently active ? Also, can you do a design with 5 states so I can map N to fourth gear? Lastly, any chance of some help with a shopping list ;D ? I'm still going to fiddle with my incoming mechanical switches but I think I need to build this for side by side play comparison. Thanks boss!

Well, actually the switch is held on by the relay. This circuit goes hand in hand with the very first drawing I made with the relay holding the button down. But instead of using two switches as in the first drawing, it uses one.
The button symbol in the second drawing is actually the N.O. limit switch on the left side of the button in the first drawing. (I got lazy in the second drawing).
I suppose you could use the second switch to turn on an led. Or just wire the led (with a dropping resistor) across the relay coil. When relay is on led is on.
As far as adding more switches, you will just need to add more AND gates, button/relay mods, and perhaps an OR gate for one of the NOR gate inputs.
When I know for sure you want to go this route I will look up part numbers for you.

Good deal, I'll take another look at it. Thanks!

So you have to rely on touch. But in many games, you cant keep your hands on the shifter, cause you need them for other functions. Even if you manage to get your hand in the correct area... remembering the position... and or even feeling it, isnt going to be a very quick and precise thing.
I also dont see how an ancient toggle switch system is anything to wow over. No offense, but It makes me laugh to think that anyone would want to use such a thing.
If you want to Wow, then make it so you cant shift at all, unless you are pressing a clutch mechanism down.
You can add put LEDs to show what gear your in on the dash. And or better yet, a digital readout of the simulated speed.
Other Wows...
- Coil based shock system when braking hard?, and or for when you get hit, as force feedback.
- Build in Engine sounds (and other sounds), into the unit. (analog throttle based pitch/changes + gear ratio)
- Transducers / bass shakers
- Blower fans that simulate wind via analog throttle speed
- Motorized system for movements.
- A ROTJ speeder game, thats actually worth playing.
- Use of three 3d-projectors in an enclosure, to fully immerse.
Anyways, remember, its not about looks. Its about good control. If people feel something isnt easy to control, they will be turned off by it, no matter how good they think it looks.

A few notes...
1) It is about looks. These are elaborate toys. You have to get the player on the thing and willing to pop a quarter in on looks alone. I'm not trying to make an end all be all car racing rig. I'm trying to design a large star wars toy that incidentally plays some racing games.
2) I'll keep my own counsel about what can wow an audience when properly executed. There are two different ways to wow you know. One is with unique, subtle, and well executed design within an identifiable theme. The other is to build something like this:

but that's not the type of wow I'm looking for.
3) You inability to imagine something as useful has no bearing on anyone else's ability to create a useful execution.
4) Speeders don't have dashes.
5) Blower fans? Seriously?
6) If you knew my comment in the very first post was about you and you did

Why did you show up where you weren't wanted?

Who can turn down a good blower?
fan that is.
I'm a fan of the fan on my dad's whirlwind. It's a neat addition to the game.

Lechuck,
If you are willing to give up the maintained button feature, you can use the same circuit to latch on the output for the button being pressed.
Of course the button will not stay in when pressed, but you could have it light up.
I have edited the drawing to show all 5 buttons, and the latching resistor (5 total). I also drew in the LEDs.
The outs will go to your PC or controller.
If the outs need to be pulsed instead always on, then you will need additional circuits to supply the pulse.
Le Chuck:
^ Excellent! Thanks so much, I'll start throwing together a parts list. This could be a great little side project.
