PSP-Style Joystick Mod

After researching portables for a long time now, I've become really interested in learning the limiting factors and difficulties of making a small N64p. Clearly, after RCP wiring or board trimming the length and width are two dimensions that cannot be easily altered. And after expansion pack relocation, the depth of the portable is only really limited by the size of the joystick. Now the Gamecube joystick is fairly large and the N64 ones are even bigger, so I began to wonder how a smaller joystick could be incorporated. I read about a few cases where a PSP joystick was tested, but ultimately these attempts were abandoned because of pot resistance issues. So I began searching around for an alternative, and what I found was this:

The Genius Maxfire Pandora Pro USB gamepad (Review). I noticed that it had a very small profile and a PSP-style joystick, so I took a chance and bought it. It was very easy to open, just inserted a flat-head screwdriver in the hole on either side and popped the case apart. Then I desoldered the joystick from the board and determined that this was most likely the pinout:

The 3rd-party controller I used to test this mod was the Boomerang 64 by Nuby. This controller is very rare, but valuable for portablizing because it has 3 separate board (one for the D-pad, Mainboard, and other buttons). In any case, it had 4 input wires for its joystick. So I wired up the joystick like so:

And it works!!! It actually works quite well. The joystick quality is much better than that of the PSP, and it is slightly more sensitive than the original N64 sticks (which is a good thing IMO). I haven't been able to test with another controller, but I would suspect that it would with a controller like the one used in this guide.

Obviously this is a great space-saving mod for experienced portablizers who wish to slim down their designs. Look at the size comparison!!!

Sorry for the blurry pic.

It's literally 1/3 the size of a Gamecube joystick or smaller! I think that, with an expansion pack relocation, you could make an extremely thin portable using this baby. Since my skills have not quite reached that level, I'd be interested to see someone incorporate this in their design in the future. Anyways, that's all for now. Hope you enjoyed this mod. :cool:
 
Yup, sticks of that size are available in a few places.

Notably some slim controllers made by MadCatz, they seem to love 'em.

You can also buy 'em brand-spanking new from places like Digi-Key.

Do you have a digikey link to a joystick like this?????

If I can buy them spanking new and just the joystick that would be awesome!!!!
 
The joystick does rotate, but i believe that this is a good feature which allows you to move the joystick about without constantly readjusting your thumb. I also despise the PSP joystick, but let me assure you that the quality of this joystick is much better. I would also be interested in these other joysticks, if anyone can verify that they work :confused:

Linked to 'em in a Thread on BenHeck at least a year ago.
Again here, at least 3 months back.

They come in different resistances (including 10KOhm, and 20KOhm, which will work for most any application.)
They also come in different rotation Angles. 45, 50, and 60 degrees.
Depending on how compact you wanna go, this can be VERY helpful.

To get an idea of size, these things are 6mm tall.
6mm is roughly the width of a pencil.

Right now, NONE are in-stock on Digi-Key.
But if you wanna see anyway:

While Digi-Key may not have any in stock, I'm sure you could find some elsewhere.
Keep in mind, these are CTS Electrocomponents 253 Series joysticks.
 
hmmmm gonna mail digikey and ask them about these. They should be perfect for portables. Didn't quite catch it when you posted it before. Thanks for the links.
 
Alright thanks!! When I get them I'll test it.

Don't have allot of time on my hands so don't post much in general. I only post if I ned to know something and sometimes to help others. It's just that so many people ask stupid question's and don't really read the forum before they ask. Everything is explained!! Just search and find out for yourself!! I just can't be bothered...
 
Can't find the joystick anywhere! Is this one about the same size as the Madcatz PS2 joysticks?
 
Any idea what the travel on it is? The PSP has 2mm of travel, it would be sweet if this one had more.
 
What would be the best way to measure the travel? Is it the full travel distance from one side to another or from the center to the edge?
