Hi!
I would be also interested to buy some of them (5~10)
So disappointed to discover this topic only now...  :'(

There are a lot of smashers here (http://smashboards.com/threads/3rd-party-replacement-joystick-guide.336450/) looking for a solution like this that combines the durability of these 3rd party joysticks with the precision of the original n64 sticks. Let us know when you have more in stock!

Hi!

I just bought and installed a pair of these gamecube styled sticks and I was really disappointed that I can't play Goldeneye with them.  :'( I'd really want to save my N64 from the scrap heap.

Is there any of these circuit boards left? I'd be very interested in buying a couple.

As mentioned in the first post of this thread, the PCB's are currently sold out. So no, I don't have any left at the moment ;)

There will be a new batch, but I'm not sure when. Maybe early 2014? February? Check this thread for new informations once a month and you won't miss the next batch!  :)

Alright I just soldered an analog stick to one of the boards. Getting the solder to stick to the holes was a pain so some of the solder joints are a bit too thick. I'm fairly satisfied nonetheless.

Is this ok micro?(sorry about the blurriness)

Weird...my solder went on just fine...only needed a little. Iron not hot enough? Bad solder?

As long as none of then are bridged though, it should be fine.

Your solder joints are pretty big (you soldered both pads), but I agree with nathan. As long as there are no shorts between them you shouldn't have any problems.

Usually it should be easy to solder in the stick and the pin header. But there are 3 solder pads that are connected to a big ground plane.
Soldering these pins can be a little bit more difficult if you got a weak soldering iron. In that case it helps to set the temperature higher and/or to hold the soldering iron tip for a longer time to the pad & pin.

WHOOPS. Now I know what I did wrong. Instead of heating up the pin from the joystick and then applying solder directly to it I instead relied on the soldering iron to melt the solder. Guess I'll keep that in mind when I make the next one.

I carefully checked if there were any bridges but found none. I suppose it will work just fine. What heat do you usually use when you solder?

Unfortunately that's a very bad way to solder. Maybe you should think about removing the solder joints (with desolder braid or a desolder pump) and solder the pins again.
In order to get a good solder joint you have to heat the pin and the pad at the same time while applying fresh solder. Always use solder with flux! :D

This video explains it quite well:
How and WHY to Solder Correctly

My solder iron is set 350 °C for "normal" solder work. When dealing with really big ground planes I'm setting the temperature at 400 or even 450 °C. (The ground plane on the N64 stick converter PCB isn't really that big ;) )

Nice video. Very helpful! The solder I used were a few leftovers I brought home with me from school and they've been sitting in a cabinet for a couple of months. When I got the solder to stick to the board I held the soldering iron to the pin for a few seconds to even out the solder. Looking on the top of the plate you can see that the solder went through properly. I currently don't own a desoldering pump but I think the joints are passable for now. Thanks for the info!

One more question though. On most soldering irons I've seen, when you apply solder on to the tip it flows in a bright gray colour like the way it should. When I applied solder to my iron it instead just kind of burned with a brown colour(presumably the flux). Is it because the iron is too corroded? Or is the solder just too old?

I finally managed to assemble one of these joysticks and I'm really happy about the results! The joystick test app shows that the upper boundary a little bigger than the lower boundary, but I'm sure that's perfectly normal. Thanks Micro!  ;D

Glad you like it! If you didn't use too much force during calibration then your test app should show at least +/- 81 steps per axis and at most +/-84 steps. So yes, a small difference is absolutely ok!  :D

Hard to say, but the moment you apply fresh solder to your iron the tip shouldn't be brown already. Maybe the temperature is too high?

Micro: Made two controllers, every one of them works like charm. Thank you, now my Nintendo 64 is perfect, with RGB mod and this beautiful stick. Looking forward for the next batch!

Wait till February!  ;D

I predict there will be enough PCB's for everyone. The stock will probably last for at least 4 to 6 weeks, just like the last time(s).
Just keep an eye on this thread in February!

This is just brilliant, can't wait till you get these back in stock!

One thing I've been wondering about is the possibility of adding some non-linear mapping options that emulate the behavior of modern analogue controllers ps/xbox etc. particularly to make n64 shooters more controllable on these sticks.
 
I think the reason shooters like GE/PD feel twitchy on these modern analogue sticks is due to the controller/most games not taking advantage of any exponential curve to map the inputs.
*I may be completely wrong calling it exponential mapping but that's what I know from RC radios where the function of adding a more gradual input curve near the deadzone is called "expo"

The original n64 stick has what feels like some hardware expo built in since it's very easy to find the end of the deadzone and it has a precise resistance that's proportional to the amount of stick input. That combination makes small /precise inputs relatively easy. Playing n64 games/shooters on more modern analogues with linear mapping means making small movements is trickier especially near the higher resistance deadzone, I always feel like there's a "hump" of resistance right at the start of the movement which is annoying.

The hori minipad works better than others on n64 I think because the overall resistance on the stick is very light so that initial hump and deadzone imprecision is less noticeable, but I believe the mapping is still linear and I would bet a nonlinear mapping could help even there.

So my question is this... with a custom coded Atmel on one of these pcbs it should be possible to write some software into the controller itself to add some more gradual input mapping/expo right?
Have you considered doing something like this if it's possible, that would be very interesting to me!

Granted I haven't tried one of these pcb and your current firmware yet so maybe the issue is already solved with your calibration approach but if not I'd be interested in your comments.

Cheers

No, I definitely won't invest time and labor to try out non-linear mapping options. The x- and y-axis position of the original N64 stick is linear to the angle of the stick... IMO the different feeling is caused by the weaker spring inside potentiometer-based sticks. The original N64 stick had a strong spring and you had to use quite some force to move the stick...

Hi there, just joined after reading about this bit of brilliance. Have a couple of older sticks which are on the way out but more importantly, I got two chinese knock off controllers a year or so ago, which are both useless for goldeneye, because of the increased sensitivity etc... They have different pcbs than the original ones and only have 4 wires going to the joystick (i'm guessing no 3.3v and ground) like these ones http://www.ebay.co.uk/itm/Thumbstick-Joystick-Repair-Replacement-for-Nintendo-64-N64-Controller-/181276567563?pt=UK_VG_Replacement_Parts_Tools&hash=item2a34ece80b  I can provide pics if wanted. My question would be, is there any way to use this pcb or an attiny24 with these controllers or is it impossible because of the different design of the main pcb? Thanks
