Inverted joystick - Nope, not this time

How could I wire the original n64 joystick to invert the y axis?

Don't think you can. This is why I had to make my joysticks rotate in my system as some systems have the joysticks in a different orientation. Why do you need to anyway, on a single system portable you just keep the orientation of the joystick in your case the same as it was in the controller.

Well, I cut the hole a little off and the only way it fits is upside down and it fits perfect.

... then you need to correct the hole, get the joystick in the right orientation and fill in the hole!

How confident are you that you can't flip it? I'm not saying you're wrong or anything, I just want to make sure that it can't be done. (I know it COULD be done, but I mean relatively easily) Anybody else ever tried this?

Yeah, it can be done. Never tried it myself necessarily, but can you probe all of the wires from the joystick to see what they measure when joystick is moved up/down?

Well thats what I was thinking, and then just trying to flip the wires for the y axis. Sounds pretty simple, but Im not 100% sure exactly how the components work, so it might not be easily possible. If I check the wires and post my results, think someone could help me figure out how to do this? It would be extremely useful to me, but others might find it useful too.

Nothing wrong with trying.

That is precisely the problem - it isn't wires it is wire - one for V and one for H. If it were two wires then you could invert, but hard when only one wire. That is why I said I thought it can't be done.

Ah, I see. That sucks. Actually after thinking a little bit, I would need to invert both the x and y axis for it to be right. Well, I might try some things. If I come up with anything, I'll share. Man, it sure would be nice if this were easy...

Found a solution. I have modified the joystick to be inverted. I'm trying to get a video of it uploaded now. I will post it when its done. This is just a prototype (it doesn't work the greatest, but it is 100% functional as far as moving the joystick and it being backwards) and I will either start over with new parts or use parts from this one. Anybody know of a good converter (free) that will convert HUGE avi's to something small?

Edit: Not quite a solution yet. I can't fit the circuit board right, so I'll have to make something different.

If you found the solution I would certainly like to see it. You don't have to made a video, just post lots of pics and descriptions of the work.

I found that Windows Movie Maker (free with XP) works great - converts .avi files of about 120Mb (the ones I took yesterday) to about 9.6Mb as .wma format; which uploads to PhotoBucket fine (they have a max for a video of 5 mins or 10Mb for a file).

Well what I did was used the guts from 2 different joysticks and added gears to it, so that instead of the things inside moving the wheels directly, there was a gear in between, so that both joysticks were inverted. The problem is, the way I made it, there is no way to put the circuit board where the wheels go into their receiver things. I'll probably post some pics later.

Edit: Here's the video I made. Not the greatest, but it works. Enjoy.

Any ideas to help with this would really be great by the way. I'm going to try a similar design now, hopefully with a nice result.

Since you seem to know, how does it measure? I haven't even taken one apart, so I dunno how it works. Is it some type of resistance or voltage?

And if it is voltage, does "down" measure as negative, and "up" as positive?
