Step 2: Easy A button

OK lets start with the A button. To follow this page I will list the steps in the order or the pictures.

1 Tri-wing screw driver. (just google tri-wing to find one to buy)
1 LED color of your choice
1 wiimote
1 15watt soldering iron
Electrical tape

First remove the screws from the wiimote. You'll notice that the wiimote won't open easy around the top and this is a real problem area for everyone, even me. The best think you can do is try to pull the case up as far as you can and put a butter knife uner the top and push down toward the bottom. If you break a peg off don't worry about it, when you done modding the wiimote just put a dab of superglue on the side and it'll hold fine.

Secondly bend your LED to look something like mine. Then your going to want to fit the LED around wiimote's PCB like image #3, once you have it aligned facing the a button solder it down. *remember what legs on the LED are Positive and Negative* (images 2 and 4 are not mine, taken form www.wiimotemods.com)
Test if you did it right by putting the PCB back in the bottom case of the wiimote and put some batterys in and push a button. If your light lights up... well you get the picture.

Next you need to break off a tab that will block your LED from fitting inside your wiimote. Look to images 5 and see for help. Put down electrical tape so the LED doesn't shine through the wiimote's case.

If its working you should see something like image #8.

Trouble shooting.
If you hit a button and your Player indicator lights come on but led doesn't.
check led connection.
Batterys are in but nothing is working.
You have most likely blown a fuse inside the wiimote.
How to fix this
First take some tweezers and look by your One and Two, there will be a little fuse with the letters F1 by it. Put your tweezer on the 2 outside points and press a button. Once your lights come on take wire and bridge the connection like i did.

Please ask for help if you need me to explain something further.
<p>Can I use smd 0603 leds for the a button and the nunchuck mod?</p>
<p>You can but I will urge against this because it will be more trouble then its worth trying to attach wires to the SMD and then isolate it so it doesnt short against the PCB (since the SMD contact are on its surface). I have tried doing something like that before and it was just to much effort and would never be reliable. If you want something lower profile then the 3MM led then buy some flat leds. If youre worried about price of 3mm leds dont be, they are very very cheap. </p>
<p>If I don't put a resistor, how fast do the batteries burn? (Nunchuck Mod)</p>
The resistor is mainly to help the LED not have to much voltage going to it causing it to burn out. The voltage on the nunchuck is 5v (if I remember right) and LEDs are usually 3v. So not using a resistor will not affect the battery in noticeable way.
Anything above 10k 1/4watt would be fine. Here is a link to some 10k ones- http://www.amazon.com/E-Projects-10k-Resistors-Watt-Pieces/dp/B00BWYS9BA/ref=sr_1_5?s=industrial&amp;ie=UTF8&amp;qid=1436792916&amp;sr=1-5&amp;keywords=resistor<br><br>However you only get 5 of them. Here is a link for 800 for 7$ more with various types (far better deal)- http://www.amazon.com/E-Projects-800-Piece-Value-Resistor/dp/B00PKCVCL4/ref=sr_1_17?s=industrial&amp;ie=UTF8&amp;qid=1436792916&amp;sr=1-17-spons&amp;keywords=resistor
<p>Would these be ok? <a href="http://www.amazon.ca/250V-Axial-Lead-Carbon-Resistors/dp/B0087ZDSV8/ref=sr_1_6?ie=UTF8&qid=1436809711&sr=8-6&keywords=resistor" rel="nofollow">http://www.amazon.ca/250V-Axial-Lead-Carbon-Resist...</a></p><p>I'm in Canada so I looked for a region friendly deal.</p>
<p>Thanks for replying! and what kind of resistor should I use? I'm fairly new to this stuff and I don't know which kind. </p>
to anyone with incompatable remotes, just solder a wire on pin 1 of the 6 pin plug on the back, and the other to ground.
Great instructable. You can get the tri wing screwdriver at <a href="http://nintendoscrewdriver.com" rel="nofollow">http://nintendoscrewdriver.com</a>
I'm surprised no one has noticed yet but the only controllers that work for the &quot;A&quot; button mod are the ones that came with wiiplay or if u bought it from store not the one that came with the console. <br/><br/>Check the link below<br/><br/><a rel="nofollow" href="http://www.wiimotemods.com/?p=6">http://www.wiimotemods.com/?p=6</a><br/>
Would love to use this but the site's images have been removed. Update link?
:( ur nunchuck is not made the same way as mine mine doesnt have the positive and negative at the same place
Mine was also different, but I figured it out. Look at where the wires come to the board. The red on one side is 3v and the black is ground. Wire it up in series with a 100 ohm resistor to get ~28ma.
it would be awesome if you could have color changing leds, is that even possible<br />
If you want to do that just get some leds from <a href="http://shop.ebay.com/i.html?LH_BIN=1&_trkparms=65%253A12%257C66%253A2%257C39%253A1%257C72%253A4727&rt=nc&_nkw=rgb+led+3mm&_sticky=1&_trksid=p3286.c0.m14&_sop=15&_sc=1">here</a>. Theyr'e pretty cheap but they do come from china usually so it takes 2-3 weeks to ship. Make sure you get some with 2 leads because the ones with 4 leads have each color control individual (Red, green, and blue) then a common anode or cathode. Using the 2 lead leds are just easier for something like this.
i have two types of colour changing leds <br>one where it just has two pins but you reverse the polarity of the terminals so +is - and - is + <br> <br>and a nother one with 3 pins and the middle is - and each of the outside pins are + fo each colour
yep! i see leds smaller than the one he used for the button mods in those solar color changing globes. they change color on their own, so its pretty cool to do
OMF!!! i only fried my wiimote and nunchuk
Try to sent it back to wal-mart and say you bought it broke. If you bought it there. If not, go buy a wiimote and a nunchuck return next day saying its broke. (And you didnt hear this from me.)
nice idea
Very Great idea! I just have one question. How many volts are going into the nunchuck and wii remote at the points you connected to? I want to find out what kind of resistors I'm going to need.
if it's 5 volts i would use a 240Ω resistor
I dont have a wiimote on hand right now but the wiimote uses 5vdc
Okay thanks
Do you know how to remotely wire a switch to operate the B (trigger button?)
can you do the same think but in a play station control?
wiimote master I have tried to mod my nunchuck and have failed constantly I will pay you $30 10 dollars a mod I will also pay for shipping if you accept please email me at kenz.lee123@yahoo.com
If you still want me to sure thing.
Was the fuse issue related to the smd leds?
So there's absolutely no way to do this if I have the remote that came with the console :-S ? I see that there is a "+" and "-" by where the vibration motor is connected, but wasn't sure if that would make the led turn on constant or not 8-} If anybody knows how to do this with the remote that came with the console, please reply.
Well if you want the led to light up when the remote vibrates then put the led on the plus and minus on the remote. But you can check the points on the remote and see if it lights up when the remote is on. I can show you what points to use if you don't have a remote with the inside that match up with the picture shown.
Oh, I know it'll flash and what not when you hook it up to the plus and mius. I just didn't know what contacts to solder to since it's a different remote. So, yeah, if you could I'd appreciate it if you could show me :)
Try connecting the LED through a rectifier, so it doesn't flash but stays on during the vibration.
If the vibration is triggered in bursts, then a capacitor is what you need, in parallel with the LED.
Man, this is great. You don't happen to live in the Dallas area, do you? I'd pay to have someone mod my controllers for me (hardly any soldering experience). I may give it a shot anyway, though.
I live in Missouri. If you really want me to make you one i can but i can't pay for shipping and ill have to have alittle money for supply's and labor. It would come around 70 bucks total. So i would try to do it yourself first and if you can't seem to get it, let me know and we'll work something out.
where in MO? around central?
More around St.Louis.
By the looks of it the resistor colours are green,blue, brown and goldso i think its 560ohms +/- 5% and i reckon 1/4 watt. If thats the samenunchuck used throughout the process (which im pretty sure it is) thatresistor should work. if this has already been posted im sorry<br />
its that led a 15-30 mcd or more?
oo thanks i gonna try
the led is flashing what do i do
on the a button
nvm fixed it
I just wanted to say thanks for the awesome easy guides! I finally finished putting in the flashing Tri-color LED into my nunchuck. Had a problem with the thumbstick pushing down on the LED, causing it to short and turn off, but fixed that by filing down the outside edge of the LED. Made a video of it to show off, so here it is:<br/><br/><a rel="nofollow" href="http://smg.photobucket.com/albums/v103/bratprince/WiiDev/?action=view&current=Wii_Nunchuck_Mod.flv">http://smg.photobucket.com/albums/v103/bratprince/WiiDev/?action=view&amp;current=Wii_Nunchuck_Mod.flv</a><br/><br/>P.S. Random shorts suck...lol.<br/>
Hey no problem, glad to help people. Great job on your mod by the way.
hi thanks for this guide, iv used it too light up one of my mote and it looks great, but my other mote differs from my first one, do u have a pic of the solder points for the differnet version of mote? thanks
There are other points on which you can solder but I haven't found them or can't remember. THe best thing to do is to make the other light up on rumble by attaching it to the rumble. Then your friends play with you and say "Why do you get the cool one?" then it rumbles and they say "O thats cool". Its what i did.
